Preface
The WHO Centre for Health Development (WHO Kobe Centre) is a research
arm of the World Health Organization based in Kobe, Japan, and has a global
mandate to conduct research into the health consequences of social, economic,
environmental and technological change and their implications for health policies.
Rapid population ageing is undeniably exerting new pressures on existing health
systems. To be effective, health systems, in considering the welfare needs of older
persons and the social services for them, must respond in timely and creative ways
to this global phenomenon and its health and socioeconomic impacts.
Today, providing adequate and cost-effective care for the growing number of
older persons, their families and community involves and requires multisectoral and
interdisciplinary integration and cooperation. But it poses challenges as well. While,
on one hand, the heterogeneity of the ageing and older population’s health status
and welfare needs differ according to their cultural and socioeconomic settings, on
the other, there is a lack of well-defined, standardized definitions and terminology for
evaluation of diversified effective models.
This obstacle to cross-sectional dialogue and exchange of ideas and views is
affecting policy formulation, research and education, as well as budgetary allocation
to implement and deliver comprehensive and integrated services in a coherent
manner. In recent years, the pressing need for standardization of terminology in
community health care for older persons has received increased attention from local
and national governments, international agencies, NGOs, the scientific and service
communities and the general public.
In response to this need, the Ageing and Health Programme of the WHO
Kobe Centre, in collaboration with the WHO Collaborating Centre for Population
Ageing: Research, Education and Policy in Adelaide, Australia, initiated a project to
develop an international glossary of terms applying to community health care and
services for older persons through consultation with global experts, both via the
Internet and in face-to-face meetings. This publication aims to define and
standardize the basic concepts and functions of community health care for older
persons and organize them into a glossary, utilizing existing WHO definitions where
appropriate, to promote a common language for cross-programme description and
information dissemination. This glossary is the first step towards the pursuit of
further collaboration in community health care development.
It is my pleasure, therefore, to release this document, entitled Glossary of
terms for community health care and services for older persons. I would also like to
take this opportunity to thank all those who made valuable contributions to this
important publication. I sincerely hope that it will be meaningful and useful in
complementing the global work of WHO.

INTRODUCTION
In recent years, the provision of adequate and cost-effective care for the
rapidly increasing number of older persons in societies has received enhanced
attention from national and local governments, international organizations,
nongovernmental organizations (NGOs), and the scientific and service communities,
as well as the general public. Major issues concern the need for an integrated and
more comprehensive approach towards meeting the special needs of older persons,
their families and communities. This requires multisectoral and interdisciplinary
cooperation. However, cross-sectional dialogue and exchange of ideas and views on
policy formulation, research, education and budgetary allocation is being hampered
by a lack of common or shared definitions and terminology.
While a number of glossaries and dictionaries relating to health and
community care have been produced by various authorities in different constituencies,
at present there is no internationally accepted common set of definitions for many of
the relevant terms used to describe health, health care and services, including
primary health care and community health care for older persons. The WHO Kobe
Centre International Meeting on Community Health Care for Older Persons in Urban
Areas, held in Bangkok, Thailand, from 10 to 12 July 2001, identified a pressing need
for standardization of terminology in community health care for older persons and, as
a major recommendation, proposed:
“Definition and standardization of basic concepts and functions and
functions of community health care for older persons into a glossary,
utilizing existing WHO definitions where appropriate, in order to
promote a common language for cross-city programme description
and information dissemination. This glossary development will be the
first step towards further collaboration”1
.
This project is the result of the WHO Kobe Centre’s commitment to produce a
glossary that, it is hoped, will facilitate international and within-country exchange in
this important area.
As a first step, the glossary was constructed via a search of the literature.
Where appropriate, existing WHO definitions have been included, but the glossary
has been expanded by reference to a number of sources, as listed in the References.
The second stage of the process involved professional review of the draft
glossary. The aim of that review was to examine:
• the relevance of the terms included;
• the choice and arrangement of words and phrases for each term; and
• identification of terms not included in the draft.
An invitation to comment on the draft glossary was sent to more than 100
individuals around the world who were identified as experts in the field of community
health care and services for older persons. Around one quarter (Appendix A)
responded with comments about individual definitions and suggestions for additional
terms.
The glossary was then the subject of a critical comprehensive review by a

meeting of experts, held in Kobe, Japan, in October 2003. A list of participants in the
workshop is included in Appendix B. As a result of that meeting, a further draft was
prepared and this final version was produced after further consultation with the
participants of the expert meeting.
The glossary is structured in a number of sections, reflecting the nature of the
terminology. The first and most expansive section provides health and community
care terms. The other sections include administrative, management and financial
terms; and statistical / research terms in community health care. The glossary
begins with a discussion of the concepts and overarching perspectives that have
guided the development of community health care for older persons.
This final glossary is the result of a collaborative effort and thanks is given to
all those who provided their time and expertise.

GUIDING CONCEPTS AND PRINCIPLES
The development of community health care for older persons is a worldwide
phenomenon that has seen the emergence of a range of programmes and services
in many different settings, principally in the developed world, but increasingly also in
developing countries. Recognizing the need for a more community-based approach
and more orientation towards older persons and their families in the delivery of
coordinated health and social services, a variety of models for community care for
ageing populations has evolved.
These developments have been guided, to varying degrees, by a range of
concepts and principles that have influenced the way in which programmes and
services have been shaped. The WHO definition of health as “…a state of complete
physical, mental and social well-being and not merely the absence of disease or
infirmity”2
has been a seminal influence, as has the WHO Alma Ata Declaration on
Primary Health Care. A range of other declarations and policy statements has also
influenced the process, including the United Nations Principles for Older Persons and
the WHO Active Ageing Policy Framework.
In addition, a broad definition of what is encompassed by community health
care has been enunciated by the WHO Centre for Health Development as
“Community health care aims to add new scope and value to the existing primary
health care approach in providing integrated health and social services by public and
private partnership to meet the increasing health and welfare needs of older persons
and their families at community level”.
There are also a number of overarching perspectives which need to be kept
in mind in development of community health care for older persons, including the
following:
Rights of older persons
Older people must be acknowledged as integral members of society and must
have the right to enjoy a good quality of life and full equity in access to the services
necessary for optimal health. The positive contribution of older persons to
development, and as a resource for their families, communities and society, must be
recognized.
Life-course perspective
Health in old age is determined by patterns of living, exposures and
opportunities for health protection over the life course. Thus, the health of older
persons should be viewed in the context of the whole of life. The life-course
perspective recognizes that ageing takes place within a sociohistorical context that
differentially provides resources to individuals based on gender, socioeconomic
status and race/ethnicity. The lifelong impact of differences in access, as well as
individual choices, can create disparities in health and well-being in later life.
Programmes directed towards health of older persons, to be ultimately effective, will
need to work collaboratively and facilitate the efforts of those seeking to improve the
lifestyles, environmental risk exposures and opportunities for health protection at
earlier ages. This is especially true for the prevention of those disorders that, at least

Records, no. 2, p. 100) and entered into force on 7 April 1948.

in part, have their origins in earlier life, such as osteoporosis, vascular diseases and
most cancers.
Healthy ageing
The primary objective of health policies directed towards older persons must
be to promote the attainment and maintenance of ‘healthy’ and ‘successful’ ageing in
advanced years. The emphasis should be on people-centred health maintenance
and improvement through promotion of a positive approach to health and healthy
lifestyles, in addition to the traditional goals of disease prevention, treatment and
rehabilitation. The challenge is to understand and promote those factors that keep
people healthy, with a focus on both personal and external resources.
Access to comprehensive care
Comprehensive health care must be available to people as they age. These
services should be aimed at minimizing the deleterious effects of disease and should
promote the achievement of personal health potential and a high quality of life for the
whole of the population.
Family / community orientation
Recognition and support should be given to the networks of older persons,
that is, their families, neighbourhoods and communities, as it is often these informal
sources of support that offer significant assistance. In the developing nations in
particular, many of the older population are an integral part of family structure and
thus intergenerational relationships and exchanges are very important.
There are also changes occurring in patterns of intergenerational co-
residence and the strength of family linkages in many places. Social changes, such
as migration, urbanization and increasing numbers of women joining the labour force,
have meant that generations of a family may live separately and, therefore,
increasing numbers of older people, particularly women, are living alone. Community
services, such as home help, community centres and day care should, therefore, be
oriented towards helping older people remain in the community as long as possible.
Cultural perspective
There is an extraordinary diversity of cultures throughout the world and within
many nations and communities. Beliefs, behaviours and attitudes to health and
ageing are greatly influenced by traditions, religious beliefs and values. These
elements must be taken into account in any approach to deal with the issues
associated with ageing. There are many positive influences upon ageing, such as
traditional respect for elders and the role of families in providing care, which need to
be fostered and utilized to contribute to attainment of improved quality of life for older
persons. Traditional health practices should be recognized and, where appropriate
and demonstrably safe, should be incorporated as complementary or alternative
treatment modalities.
Gender variation
The importance of recognizing and responding to the differences in
experience of ageing between men and women has been increasingly acknowledged.
Differentials in mortality, morbidity and disability have been widely described.
Women are more likely than men to suffer poverty and reduced lifetime economic
4

opportunities that negatively impact on late life resources. In addition, the vital role of
women as carers is an important consideration.
Cohort perspective
Research studies have demonstrated substantial variation between different
cohorts of older people. Any analysis of ageing issues and programmes designed to
deal with these should take account, as far as possible, of cohort variations.
Planning processes need to consider that the recipients of programmes now at the
planning stage may ultimately be younger cohorts with somewhat differing
experiences, attitudes and expectations of ageing than the present older persons.
This is especially true of countries that are rapidly developing demographically and
socioeconomically.
Age-friendly services
The WHO Perth Framework for Age-Friendly Community-Based Health Care
2002 notes:
“As an overarching principle, health care services must aim to provide
the highest attainable standards of health, conducive to promoting
active ageing and health over the life course and to maintaining life in
dignity. Towards this end, health care services must meet the
following essential criteria: availability; accessibility;
comprehensiveness; quality; efficiency; non-discrimination; and age-
responsiveness…. The principle of non-discrimination should be
upheld to ensure equal distribution and treatment, as well as the
prevention of abuse, taking into account the economic, social,
psychological and physical vulnerability of older persons”.
Integration of community health and welfare services
“Systems that integrate and coordinate health and welfare
programmes will be both more effective and efficient in addressing the
type of health care needs of many older persons. Integration is a
basic requirement both in and among health and welfare sectors. The
community health care (CHC) framework is proposed as a means of
updating the PHC approach to better address the needs of older
adults. The proposed approach provides a framework for integrating
health and welfare systems and strengthens older peoples’
connections to their family and communities regardless of abilities or
disabilities”3
.
The formulation of this glossary has, wherever possible and appropriate, been
guided by the broad principles set out above.

HEALTH AND COMMUNITY CARE TERMS
A
abuse Mistreatment or neglect of an older person(s) through the intentional or
unintentional behaviour of another person(s). Abuse may be collectively
perpetrated or politically motivated. This abuse may be physical, psychological,
sexual, financial and/or systemic. One type of abuse is usually accompanied by
other types.
See also “neglect”.
access The ability of an individual or a defined population to obtain or receive
appropriate health care. This involves the availability of programmes, services,
facilities and records. Access can be influenced by such factors as finances
(insufficient monetary resources); geography (distance to providers); education
(lack of knowledge of services available); appropriateness and acceptability of
service to individuals and the population; and sociological factors (discrimination,
language or cultural barriers).
accessibility Removal of the barriers to entering and receiving services or working
within any health care setting.
active ageing The process of optimizing opportunities for health, participation and
security in order to enhance quality of life as people age.
activities of daily living (ADL) A concept of functioning – activities of daily living
are basic activities that are necessary to independent living, including eating,
bathing and toileting. This concept has several assessment tools to determine an
individual’s ability to perform the activity with or without assistance.
See related “instrumental activities of daily living (IADL)”.
activity coordinator A trained staff member who is responsible for leisure activities
in a health care programme. Activity coordinators develop programmes for
people based on individual abilities and interests.
acute care / acute health care Care that is generally provided for a short period of
time to treat a new illness or a flare-up of an existing condition. This type of care
may include treatment at home, short-term hospital stays, professional care,
surgery, X-rays and scans, as well as emergency medical services.
acute disease / illness A disease which is characterized by a single or repeated
episode of relatively rapid onset and short duration from which the patient usually
returns to his/her normal or previous state or level of activity. An acute episode of
a chronic disease (for example, an episode of diabetic coma in a patient with
diabetes) is often treated as an acute disease.
adaptation (of residence) Permanent fixtures or alterations to a home to help
someone get about or manage better (distinguished from ‘aids’ or ‘equipment’,
which are more portable).
adapted living facility / housing Housing that has been specially built for, or
changed to a certain standard to accommodate people with disabilities.
admission The initiation of care, usually referring to inpatient care, although the
term may be used for day or community care as well.
7

adult care home / residential facility A residence which offers housing and
personal care services to a number of residents. Services (such as meals,
supervision and transportation) are usually provided by the owner or manager.
Usually 24-hour professional health care is not provided on site.
See also “assisted living facility”.
adult day care See “day care centre”.
adult placement A type of foster care in which an older person lives with an
approved family.
advance care planning Planning in advance for decisions that may have to be
made prior to incapability or at the end of life. People may choose to do this
planning formally, by means of advance directives, or informally, through
discussions with family members, friends and health care and social service
providers, or a combination of both methods.
advance directive A mechanism by which a competent individual expresses his or
her wishes should circumstances arise in which he or she no longer is able to
make rational and sound decisions regarding his or her medical treatment.
Usually ‘advance directive’ refers to orders for withholding and/or withdrawing life
support treatments at the end of life, made by writing living wills and/or granting
power of attorney to another individual.
adverse event / reaction Any undesirable or unwanted consequence of a
preventive, diagnostic or therapeutic procedure.
advocacy for health A combination of individual and social actions designed to
gain political commitment, policy support, social acceptance and systems support
for a particular health goal or programme. Advocacy also has a role in creating
awareness in the minds of the community regarding the rights of older persons.
advocacy scheme Services which seek to ensure that a person’s views are heard
and his or her interests represented.
advocate 1 A person who acts on behalf of another, usually for a cause or plea.
2 To support or suggest an idea, development or way of doing something.
aetiology / aetiological See “etiology”.
after-care Care provided to individuals after their release from institutional care.
age discrimination Unfair or unequal treatment of people on the grounds of age.
aged The state of being old. A person may be defined as aged on a number of
criteria including chronological age, functional assessment, legislation or cultural
considerations.
aged care Services provided to people deemed to be aged or elderly.
aged care assessment team Multidisciplinary team of health professionals that is
responsible for comprehensive assessments of the needs of older persons,
including their suitability for hospital, home or institutional care.
ageing / aging The lifelong process of growing older at cellular, organ or whole-
body level throughout the life span.
8

ageing / aging in place Meeting the desire and ability of people, through the
provision of appropriate services and assistance, to remain living relatively
independently in the community in his or her current home or an appropriate level
of housing. Ageing in place is designed to prevent or delay more traumatic
moves to a dependent facility, such as a nursing home.
ageing of the population See “population ageing”.
ageism The negative stereotyping or discrimination of people on the basis of age.
agent (of disease) A factor, such as a micro-organism, chemical substance, form
of radiation, or excessive cold or heat, which is essential for the occurrence of a
disease. A disease may be caused by more than one agent acting together or, in
the case of deficiency diseases, by the absence of an agent.
aid An item, such as a walking frame or a shower chair, which helps people to
manage the activities of daily living.
alarm See “emergency alarm”.
allied health personnel Specially trained and licensed (when necessary) people in
occupations that support and supplement the functions of health professionals.
For the older population, such health personnel may include home health workers
and nursing assistants.
See also “auxiliary worker”.
allopathy A system of medicine based on the theory that successful therapy
depends on creating a condition antagonistic to, or incompatible with, the
condition to be treated. Thus, drugs such as antibiotics are given to combat
diseases caused by the organisms to which they are antagonistic.
alternative and complementary health care / medicine / therapies Health care
practices that are not currently an integral part of conventional medicine. The list
of these practices changes over time as the practices and therapies are proven
safe and effective and become accepted as mainstream health care practices.
These unorthodox approaches to health care are not based on biomedical
explanations for their effectiveness. Examples include homeopathy, herbal
formulas, and use of other natural products as preventive and treatment agents.
alternative medical system A complete system of theory and practices that has
evolved independently of, and often prior to, the conventional biological approach.
Many are traditional systems of medicine that are practised by individual cultures
throughout the world. Traditional Oriental medicine and Ayurveda, India’s
traditional system of medicine, are two examples.
ambulatory care Health services provided on an outpatient basis in contrast to
services provided in the home or to persons who are inpatients. While many
inpatients may be ambulatory, the term ambulatory care usually implies the
patient travels to a location to receive services and no overnight stay in hospital is
required. Many surgeries and treatments are now provided on an outpatient
basis, while previously they were considered reason for inpatient hospitalization.
ambulatory setting A type of institutional organized health setting in which health
services are provided on an outpatient basis. Ambulatory care settings may be
either mobile (when the facility is capable of being moved to different locations) or
fixed (when the person seeking care must travel to a fixed service site).
9

ancillary service Support service provided in conjunction with medical or hospital
care. Such services include laboratory, radiology, physical therapy and inhalation
therapy, among others.
anthropometrics The measurement of the size and proportions of the human body.
appraisal See “geriatric assessment”.
appropriate health technology Methods, procedures, techniques and equipment
that are scientifically valid, adapted to local needs and acceptable to those who
use them and to those for whom they are used, and that can be maintained and
utilized with resources the community or country can afford.
assessment See “geriatric assessment”.
assessment appeal process A process that allows a person who has been
assessed to dispute the assessment, and which provides for the assessment to
be changed.
assessment system A structured process developed to ensure that assessment is
relevant, consistent, fair and valid. The system requires rules of operation, a
regular review process and competent assessors.
assisted living See “residential care services”; “assisted living facility”.
assisted living facility / assisted care living facility Establishment which
provides accommodation and care for older or disabled persons who cannot live
independently but do not need nursing care. Residents are also provided with
domestic assistance (meals, laundry, personal care).
assisted suicide The act of intentionally killing oneself with the assistance of
another who provides the knowledge, means or both.
assistive device Equipment that enables an individual who requires assistance to
perform the daily activities essential to maintain health and autonomy and to live
as full a life as possible. Such equipment may include, for example, motorized
scooters, walkers, walking sticks, grab rails and tilt-and-lift chairs.
assistive technology An umbrella term for any device or system that allows
individuals to perform tasks they would otherwise be unable to do or increases
the ease and safety with which tasks can be performed.
attendant care Personal care for people with disabilities in non-institutionalized
settings generally by paid, non-family carers.
autonomy The perceived ability to control, cope with and make personal decisions
about how one lives on a daily basis, according to one’s own rules and
preferences.
auxiliary worker A worker who has less than full professional qualifications in a
particular field and is supervised by a professional worker.
avoidable hospital condition / admission A medical condition for which
hospitalization could have been avoided if ambulatory care had been provided in
a timely and efficient manner.
10

B
basic health service A network of health units providing essential health care to a
population. Basic health services include communicable disease control,
environmental sanitation, maintenance of records for statistical purposes, health
education of the public, public health nursing and medical care.
bereavement A process of loss, grief and recovery, usually associated with death.
board and care home See “adult care home”.
burden of disease The total significance of disease for society beyond the
immediate cost of treatment. It measures years of life lost to ill-health as the
difference between total life expectancy and disability-adjusted life expectancy.
C
care The application of knowledge to the benefit of a community or individual.
There are various levels of care:
intermediate care: A short period of intensive rehabilitation and treatment to
enable people to return home following hospitalization or to prevent admission to
hospital or residential care.
primary care: Basic or general health care focused on the point at which a
patient ideally first seeks assistance from the medical care system. It is the basis
for referrals to secondary and tertiary level care.
secondary care: Specialist care provided on an ambulatory or inpatient basis,
usually following a referral from primary care.
tertiary care: The provision of highly specialized services in ambulatory and
hospital settings.
care chain / chain of care 1 A well planned entity of inter- and intra-organizational
care processes to solve the complexity of problems of an individual, and
accompanied by systematic follow-up actions. Care chains are integrated to the
extent that there are no gaps, barriers or breaks in the process leaving the older
person without proper care. 2 A description of the different parts of care.
care-dependent Persons with chronic illnesses and/or impairments which lead to
long-lasting disabilities in functioning and reliance on care (personal care,
domestic life, mobility, self direction).
care home A residential facility that provides accommodation and offers a range of
care and support services. Care homes may provide a limited number of services
to support low dependency or may provide a wide range of services to cater for
the continuum from low to high dependency care.
See “assisted living facility”; “high dependency care facility”.
care management See “case management”.
care need Some state of deficiency decreasing quality of life and affecting a
demand for certain goods and services. For the older population, lowered
functional and mental abilities are decisive factors that lead to the need for
external help.
11

care package A combination of services designed to meet a person’s assessed
needs.
care pathway An agreed and explicit route an individual takes through health and
social care services. Agreements between the various providers involved will
typically cover the type of care and treatment, which professional will be involved
and their level of skills, and where treatment or care will take place.
See also “care plan”; “care programme”.
care plan A dynamic document based on an assessment which outlines the types
and frequency of care services that a client receives. It may include strategies,
interventions, continued evaluation and actions intended to help an older person
to achieve or maintain goals.
care programme A documented arrangement of integrated care, based on the
analysed needs of a specific group of people, from intake to supply of care and
services, as well as the intended outcomes, and including a description of the way
the arrangement should be applied in order to match the needs of individual
persons.
caregiver A person who provides support and assistance, formal or informal, with
various activities to persons with disabilities or long-term conditions, or persons
who are elderly. This person may provide emotional or financial support, as well
as hands-on help with different tasks. Caregiving may also be done from long
distance.
See also “formal assistance”; “informal assistance”.
caregiver burden The emotional, physical and financial demands and
responsibilities of an individual’s illness that are placed on family members,
friends or other individuals involved with the individual outside the health care
system.

intervention to enable care to continue.
carer See “caregiver”; “formal assistance”; “informal assistance”.
case conference A meeting of all professionals (often including carers) interested
in an individual’s care.
case management A continuous process of planning, arranging and coordinating
multiple health care services across time, place and discipline for persons with
high-risk conditions or complex needs in order to ensure appropriate care and
optimum quality, as well as to contain costs.
case mix A method by which a health care provider measures the service needs of
the patient population. It may be based on such things as age, medical diagnosis,
severity of illness or length of stay.
case severity A measure of intensity or gravity of a given condition or diagnosis for
an older person.
12

catchment area A geographic area defined and served by a health programme or
institution, such as a hospital or community health centre, which is delineated on
the basis of such factors as population distribution, natural geographic boundaries,
and transportation accessibility. By definition, all residents of the area needing
the services of the programme are usually eligible for them, although eligibility
may also depend on additional criteria.
cause of death For the purpose of national mortality statistics, every death is
attributed to one underlying condition, based on information reported on the death
certificate and using the international rules for selecting the underlying cause of
death from the reported conditions.
See “International Statistical Classification of Diseases and Related Health
Problems, tenth revision (ICD-10)”.
cause-of-death ranking Cause-of-death ranking for adults is based on the List of
72 Selected Causes of Death, HIV Infection, and Alzheimer's Disease. The List
was adapted from one of the special lists for mortality tabulations recommended
for use with the International Classification of Diseases, ninth revision. Two group
titles – “Major cardiovascular diseases” and “Symptoms, signs, and ill-defined
conditions” – are not ranked based on the list of 72 selected causes. In addition,
category titles that begin with the words “other” and “all other” are not ranked.
The remaining category titles are ranked according to number of deaths to
determine the leading causes of death. When one of the titles that represents a
subtotal is ranked (for example, unintentional injuries), its component parts are
not ranked (in this case, motor vehicle crashes and all other unintentional injuries).
centenarian A person who is 100 years or older.
challenging behaviour Behaviour which is difficult and complex to manage, even
within a therapeutic environment. The behaviour may be related to organic or
non-organic predisposing factors.
chiropody See “podiatry”.
chiropractice A system of medicine based on the theory that disease is caused by
malfunction of the nervous system, and that normal function of the nervous
system can be achieved by manipulation and other treatment of the structures of
the body, primarily the spinal column. A practitioner is a chiropractor, Doctor of
Chiropractic (DC).
choice Those seeking care have options between and within health care units,
including opportunities for gaining specialist care and second opinions, or to deny
care.

cleaning.
chronic care The ongoing provision of medical, functional, psychological, social,
environmental and spiritual care services that enable people with serious and
persistent health and/or mental conditions to optimize their functional
independence and well-being, from the time of condition onset until problem

complex and ongoing.
13

chronic condition / disease A disease which has one or more of the following
characteristics: is permanent; leaves residual disability; is caused by non-
reversible pathological alternation; requires special training of the patient for
rehabilitation; or may be expected to require a long period of supervision,
observation or care.
chronic hospital A facility that serves patients who do not need acute care or care
in another kind of specialty hospital and whose needs for frequency of monitoring
by a medical practitioner and for frequency and duration of nursing care exceed
the requirements for care in a comprehensive care or extended care facility.
classification of disease Arrangement of diseases into groups having common
characteristics. Useful in efforts to achieve standardization in the methods of
presenting mortality and morbidity data from different sources and, therefore, in
comparability. May include a systematic numerical notation for each disease
entry. Examples include the International Statistical Classification of Diseases,
Injuries and Causes of Death.
client A person who seeks or receives services or advice.
client group A category in a classification or typology of clients. Clients can be
classified in various dimensions, e.g. by dependency level, by diagnosis.
client quality The outcome of care/service from an individual/user’s point of view.
It is how well the care service supports the client/user to improve his/her quality of
life.
clinic A facility, or part of one, devoted to diagnosis and treatment or rehabilitation
of outpatients.
See “outpatient services”; “ambulatory care”.
clinical care Professional specialized or therapeutic care that requires ongoing
assessment, planning, intervention and evaluation by health care professionals.

accountable for continuously improving the quality of their services and
safeguarding high standards of care.
clinical information system An information system that collects, stores and
transmits information that is used to support clinical applications (e.g.
transmission of laboratory test results, radiology results, prescription drug orders).
Electronic medical records are one method by which clinical information systems
can be created.
14

clinical observation Clinical information, excluding information about treatment
and intervention. Clinical information that does not record an intervention is by
nature a clinical observation. The observer may be the patient or related person
(information about symptoms, family history, occupation or lifestyle) or a health
care professional (information about physical signs, measurements, properties
observed or diagnoses). While information about the nature of a planned or
performed treatment is excluded by the definition, clinical observations may be
recorded on the results of a treatment, on progress during the course of a
treatment, or on the result of a treatment.
clinical pathway A multidisciplinary set of daily prescriptions and outcome targets
for managing the overall care of a specific type of patient, e.g. from pre-admission
to post-discharge for patients receiving inpatient care. Clinical pathways are often
intended to maintain or improve quality of care and decrease costs for patients in
particular diagnosis-related groups.
clinical performance measure An instrument that estimates the extent to which a
health care provider delivers clinical services that are appropriate for each
patient's condition; provides them safely, competently and in an appropriate time-
frame; and achieves desired outcomes in terms of those aspects of patient health
and patient satisfaction that can be affected by clinical services.
clinical practice guideline A systematically developed statement to assist
practitioner and patient decisions about appropriate health care for one or more
specific clinical circumstances.
clinical significance A conclusion that an intervention has an effect that is of
practical meaning to older persons and health care providers. Even though an
intervention is found to have a statistically significant effect, this effect may not be
clinically significant. In a trial with a large number of participants, a small
difference between treatment and control groups may be statistically significant,
but clinically unimportant. In a trial with few participants, an important clinical
difference may be observed that does not achieve statistical significance. (A
larger trial may be needed to confirm that this is a statistically significant
difference).
clinical trial A controlled research study of the safety and effectiveness of drugs,
devices or techniques that occurs in four phases, starting with the enrolment of a
small number of people, to the later stages in which thousands of people are
involved prior to approval by the licensing authorities (for example, the Food and
Drug Administration).

members of a group or society. Other members of the group or society generally
provide care on a voluntary basis.
community A group of people, often living in a defined geographical area, who may
share a common culture, values and norms, and are arranged in a social
structure according to relationships which the community has developed over a
period of time. Members of a community gain their personal and social identity by
sharing common beliefs, values and norms which have been developed by the
community in the past and may be modified in the future. They exhibit some
awareness of their identity as a group, and share common needs and a
commitment to meeting them.
community action for health Collective efforts by communities which are directed
towards increasing community control over the determinants of health and
thereby improving health.

sites, visiting nurses or home health aides, adult day care and homemaker
services.
community care Services and support to help people with care needs to live as
independently as possible in their communities.
community empowerment Involves individuals acting collectively to gain greater
influence and control over the determinants of health and the quality of life in their
communities. Community empowerment is an important goal in community action
for health.
community equipment See “aid”.
community health The combination of sciences, skills and beliefs directed towards
the maintenance and improvement of the health of all the people through
collective or social actions. The programmes, services and institutions involved
emphasize the prevention of disease and the health needs of the population as a
whole. Community health activities change with changing technology and social
values, but the goals remain the same.
community health care Includes health services and integrates social care. It
promotes self care, independence and family support networks.
16

community health centre An ambulatory health care programme, usually serving a
catchment area which has scarce or non-existent health services or a population
with special health needs. These centres attempt to coordinate federal, state and
local resources in a single organization capable of delivering both health and

community health needs assessment The ongoing process of evaluating the
health needs of a community. Usually facilitates prioritization of needs and a
strategy to address them.
community health worker A trained health worker who works with other health
and development workers as a team. The community health worker provides the
first contact between the individual and the health system. The types of
community health worker vary between countries and communities according to
their needs and the resources available to meet them. In many societies, these
workers come from and are chosen by the community in which they work. In
some countries they work as volunteers; normally those who work part-time or
full-time are rewarded, in cash or in kind, by the community and the formal health
services.
community involvement The active involvement of people living together in some
form of social organization and cohesion in the planning, operation and control of
primary health care, using local, national and other resources. In community
involvement, individuals and families assume responsibility for their and their
communities' health and welfare, and develop the capacity to contribute to their
own and their communities’ development.
community medicine The study of health and disease in the population of a
defined community or group and the practice of medicine concerned with groups
or populations rather than individual patients.
community mental health centre An entity which provides comprehensive mental
health services (principally ambulatory), primarily to individuals residing or
employed in a defined catchment area.
community visitor scheme A scheme utilizing volunteers to visit, spend time with
and become friends with an older person in his/her place of residence.
co-morbid condition Conditions that exist at the same time as the primary
condition in the same patient (e.g. hypertension is a co-morbidity of many
conditions, such as diabetes, ischemic heart disease, end-stage renal disease,
etc.). Two or more conditions may interact in such a way as to prolong a stay in
hospital or hinder successful rehabilitation.
compliance A measure of the extent to which persons undergo an assigned
treatment or regimen, e.g. taking drugs, undergoing a medical or surgical
procedure, following an exercise regimen, or abstaining from smoking.
comprehensive geriatric assessment (CGA) A process which includes a

diagnosis to rehabilitation.
comprehensive health system A health system that includes all the elements
required to meet all the health needs of the population.
computer-assisted diagnosis The use of information technology to assist health
care professionals in diagnosis. This usually involves a dialogue between a
computer system and a clinician. The systems are generally regarded as support
systems for clinicians; the final responsibility for decision-making resides with the
clinician.
computer-assisted therapy The application of computer technology to therapy.
concurrent review A review that occurs during the course of patient treatment.
Concurrent review enables the medical practitioner or other health care provider
to evaluate whether the course of treatment is consistent with expectations for the
usual management of a clinical case. The review may also facilitate early
identification of negative consequences of treatment (e.g. complications, failure to
respond to therapy) that will affect the length of the care episode and outcomes.
confidence A sense of assurance, faith or trust in a person, thing or oneself.
confidentiality Privacy in the context of privileged communication (such as patient-
doctor consultations) and medical records is safeguarded.
congregate housing Individual apartments in which residents may receive some
services, such as a daily meal with other tenants. Buildings usually have some
communal areas, such as a dining room and lounge, as well as additional safety
measures such as an emergency call system.
congregate meals programme Delivery of meals and socialization activities to
older adults in a designated location.
consensus development Various forms of group judgement in which a group (or
panel) of experts interacts in assessing an intervention and formulating findings
by vote or other informal or formal means, involving such techniques as the
nominal group and Delphi techniques.

health care services over any given period of time, with the level of care varying
according to individual needs.
continuum of care The entire spectrum of specialized health, rehabilitative and
residential services available to the frail and chronically ill. The services focus on
the social, residential, rehabilitative and supportive needs of individuals, as well
as needs that are essentially medical in nature.
contraindication A clinical symptom, circumstance, condition indicating that the
use of an otherwise advisable intervention would be inappropriate. A
contraindication may be absolute or relative. An absolute contraindication is a
situation which makes a particular treatment or procedure absolutely inadvisable.
A relative contraindication is a condition which makes a particular treatment or
procedure somewhat inadvisable, but does not rule it out (for example, X-rays in
pregnancy).
conventional medicine Medicine as practised by holders of a medical degree and
their allied health professionals, some of whom may also practise complementary
and alternative medicine.
See “alternative and complementary health care”.
coordinated care A collaborative process that promotes quality care, continuity of
care and cost-effective outcomes which enhance the physical, psychosocial and
vocational health of individuals. It includes assessing, planning, implementing,
coordinating, monitoring and evaluating health-related service options. It may
also include advocating for the older person.
coordination within the health sector Organized collaboration, as necessary,
among those providing the services at the same and different levels of the health
system in order to make the most efficient use of resources, as well as within and
among the various categories of health workers following agreement on the
division of labour. It also means coordination of programmes or services to avoid
duplication or inconsistency.
coping An adaptive or otherwise successful method of dealing with individual or
environmental situations that involve psychological and physiological stress or
threat.
core activities Activities which are essential for daily living, such as self care,
mobility and communication.
cost of illness The personal cost of acute or chronic disease. The cost to the
patient may be an economic, social or psychological cost or loss to himself, his
family or community. The cost of illness may be reflected in absenteeism,
productivity, response to treatment, peace of mind, quality of life, etc. It differs
from health care costs in that this concept is restricted to the cost of providing
services related to the delivery of health care, rather than the impact on the
personal life of the patient.
See “burden of disease”.
19

counselling Interaction offering an opportunity for a person to explore, discover
and clarify ways of living with greater well-being, usually in a one-to-one
discussion with a trained counsellor.

density, fertility, mortality, growth, age distribution, migration and vital statistics,
and the interaction of all of these with social and economic conditions.
dependency Reliance on others to provide physical, mental and/or social support.
dependency ratio An indicator used in population studies to measure the portion of
the population which is economically dependent on active age groups. It is
calculated as the sum of the 0-14 year-olds and the over 60 or 65 year-olds,
depending on the working age limit considered, divided by the number of people
aged between 15 and 59 or 64, respectively.
developmental disability A severe, chronic disability which is attributable to a
mental or physical impairment or combination of mental and physical
impairments; is manifested before the person attains the age of 22; is likely to
continue indefinitely; results in substantial functional limitations in three or more of
the following areas of major life activity: self care, receptive and expressive
language, learning, mobility, self direction, capacity of independent living,
economic self-sufficiency; and reflects the person's need for a combination and
sequence of special, interdisciplinary or generic care treatments or services which
are of lifelong or extended duration and are individually planned and coordinated.
diagnosis The process of determining health status and the factors responsible for
producing it. It may be applied to an individual, family, group or community. The
term is applied both to the process of determination and to its findings.
See also “principal diagnosis”.
diagnosis-related group (DRG) 1 Represents classes of hospital patients with
similar clinical characteristics. DRGs form a clinical grouping system which
describes hospital discharges according to medical condition. 2 A system used
for payment under prospective payment systems. It classifies treatments by

principal diagnosis, secondary diagnosis, surgical procedures, age, sex and
presence of complications.
dignity The right of individuals to be treated with respect as persons in their own
right.
direct patient care Any activities by a health professional involving direct
interaction, treatment, administration of medications or other therapy or
involvement with a patient.
21

disability Any restriction or lack (resulting from an impairment) of ability to perform
an activity in the manner, or within the range, considered to be normal for a
human being. The term disability reflects the consequences of impairment in
terms of functional performance and activity by the individual. Disabilities thus
represent disturbances at the level of the person.
See also “handicap”; “impairment”.
disability-adjusted life expectancy A modification of conventional life expectancy
to account for time lived with disability. It is the number of healthy years of life
that can be expected on average in a given population. It is generally calculated

expectation of years of life for the loss on account of disability, using explicit
weights for different health states.
disability-adjusted life years (DALYs) The number of healthy years of life lost due
to premature death and disability.
disability postponement Measures that can be initiated among those with a
disease, usually a chronic disease, to lessen or delay the impact of disability from
that disease, e.g. averting renal complications among those with diabetes.
discharge The release of a patient from a provider's care, usually referring to the
date at which a patient checks out of a hospital.
discharge planning A process by which an admitted inpatient's needs on
discharge are anticipated, planned for or arranged.
disease A failure of the adaptive mechanisms of an organism to counteract
adequately, normally or appropriately to stimuli and stresses to which the
organism is subjected, resulting in a disturbance in the function or structure of
some part of the organism. This definition emphasizes that disease is
multifactorial and may be prevented or treated by changing any or a combination
of the factors. Disease is a very elusive and difficult concept to define, being
largely socially defined. Thus, criminality and drug dependence are presently
seen by some as diseases, when they were previously considered to be moral or
legal problems.
disease control All the measures designed to prevent or reduce as much as
possible the incidence, prevalence and consequences of disease, such as the
control of disease vectors, the removal or reduction of the influence of
predisposing factors in the environment, immunization and curative care.
disease management The process of identifying and delivering, within selected
populations (e.g. people with asthma or diabetes), the most efficient, effective
combination of resources, interventions or pharmaceuticals for the treatment or
prevention of a disease. Disease management could include team-based care,
where medical practitioners and/or other health professionals participate in the
delivery and management of care. It also includes the appropriate use of
pharmaceuticals.
disease prevention See “prevention”.
dissemination Any process by which information is transmitted (made available or
accessible) to intended audiences or target groups.
22

do not resuscitate order An advance directive based on the premise that a person
may prefer to die than live when the quality of life available after cardiopulmonary
resuscitation (CPR) is likely to be worse than before. In such circumstances, a
patient has the right not to be resuscitated and to be allowed to die.
domiciliary care Care provided in an individual’s own home.
drug therapy The use of drugs to treat a medical problem, to improve a person’s
condition or to otherwise produce a therapeutic effect.
drug utilization review (DUR) A formal programme for assessing drug prescription
and use patterns. DURs typically examine patterns of drug misuse, monitor
current therapies, and intervene when prescription or utilization patterns fall
outside pre-established standards. DUR is usually retrospective, but can also be
performed before drugs are dispensed.
durable power of attorney (enduring power of attorney) A written legal
document in which a person appoints another individual to act as his/her agent for
the purposes of health care decision-making in the event that he/she is unable or
unwilling to make such decisions.
See also “advance directive”.
duty of care A legal requirement that a person act towards others and the public
with the watchfulness, attention, caution and prudence that a reasonable person
would use in the circumstance. If a person’s actions do not meet this standard of
care, then the acts are considered negligent, and any damages resulting may be
claimed in a lawsuit for negligence.
dying well Dying in a way the person prefers. Dying well may include pain relief,
operating at the highest possible level of functioning, resolving long-standing
conflicts and satisfying final wishes.
E

assert their rights.
enabling Taking action in partnership with individuals or groups to empower them,
through the mobilization of human and material resources, to promote and protect
their health.
encounter A contact between an individual and a care provider.

biological, social, cultural and other factors.
epidemic A group of cases of a specific disease or illness clearly in excess of what
one would normally expect in a particular geographic area. There is no absolute
criterion for using the term epidemic; as standards and expectations change, so
might the definition of an epidemic, e.g. an epidemic of violence.
epidemiology The study of the various factors influencing the occurrence,
distribution, prevention and control of disease, injury and other health-related
events in a defined population. Epidemiology utilizes biology, clinical medicine,
and statistics in an effort to understand the etiology (causes) and course of illness
and/or disease. The ultimate goal of the epidemiologist is, not merely to identify
underlying causes of a disease, but to apply findings to disease prevention and
health promotion.
episode The period in which a health problem or illness exists, from its outset to its
resolution.
episode of care The description and measurement of the various health care
services and encounters rendered in connection with an identified injury or period

Principles typically refer to respect for, and the dignity of, human beings. Basic
dimensions are “autonomy” (respect for self determination), “well-being” (respect
for happiness, health and mental integrity) and “social justice” (justifiable
distribution of scarce goods and services). More specifically, ethics of care refer
to ethical standards developed for the care professions which are designed to
implement ethical principles in the practice of care provision.
ethics committee A committee that can have a number of roles in relation to ethics.
For example, it may develop policy relative to the use and limitation of treatment;
serve as a resource for individuals and their families regarding options for
terminal illness; or assess research projects with respect to the appropriate
application of ethical principles.
ethnicity A social group within a cultural and social system that shares complex
traits of religious, linguistic, ancestral and/or physical characteristics.
etiology / etiologic Causes or causality, usually applying to disease.
euthanasia A deliberate act undertaken by one person with the intention of either
painlessly putting to death or failing to prevent death from natural causes in cases
of terminal illness or irreversible coma of another person. The term comes from
the Greek expression for “good death”.
evidence-based care The conscientious, explicit and judicious use of current best
evidence in making decisions about the care of individuals. This approach must
balance the best external evidence with the desires of the individual and the
clinical expertise of health care providers.
evidence-based decision-making In a policy context, evidence-based decision-
making is the application of the best available scientific evidence to policy
decisions about specific treatments or care, as well as changes in the delivery
system.
expectation of life The average number of years an individual of a given age is
expected to live if current mortality rates continue to apply.
See “life expectancy”.

in the form of guidelines for diagnosis, treatment and care indications, about older
persons, or other authoritative information (for example, a computer database on
drug indications, contraindications and interactions).
family practice A form of specialty practice in which medical practitioners provide
continuing comprehensive primary care within the context of the family unit.
25

formal assistance Help provided to persons with one or more disability by
organizations, or individuals representing organizations (whether profit-making or
non-profit-making, government or private), or by other persons (excluding family,
friends or neighbours as described in informal help) who provide assistance on a
regular, paid basis and who are not associated with any organization.
formal care See “formal assistance”.
formulary A list of drugs, usually by their generic names, and indications for their
use. A formulary is intended to include a sufficient range of medicines to enable
medical practitioners, dentists and, as appropriate, other practitioners to prescribe
all medically appropriate treatment for all reasonably common illnesses. In some
health plans, providers are limited to prescribing only drugs listed on the plan's
formulary.

and occupied by individuals or families, offering a place of residence, meals,
housekeeping services, minimum supervision, and personal care for a fee to non-
family members who do not require supervision by skilled medical personnel.
frail older person An older person in need of a substantial level of care and
support.
functional status The extent to which an individual is able to perform activities that
are associated with the routines of daily living.
See “activities of daily living”; and “instrumental activities of daily living”.
functionally disabled A person with a physical or mental impairment that limits the
individual's capacity for independent living.
futile medical treatment Treatment that is usually considered unable to produce
the desired benefit either because it cannot achieve its physiological aim or
because the burdens of the treatment are considered to outweigh the benefits for
the particular individual. There are necessary value judgements involved in
coming to an assessment of futility. These judgements must consider the
individual’s, or proxy’s, assessment of worthwhile outcome. They should also
take into account the medical practitioner or other provider’s perception of intent
in treatment. They may also take into account community and institutional
standards, which in turn may have used physiological or functional outcome
measures.
G
gatekeeper A health professional, who may be a medical practitioner, nurse or
other professional, who has the first encounter with an individual and controls the
individual's entry into the health care system.
general hospital A hospital providing a variety of services, including medicine and

ADMINISTRATIVE, MANAGEMENT AND FINANCIAL
TERMS
A
acceptable risk A risk that has minimal detrimental effects or for which the benefits
outweigh the potential hazards.
accreditation A process whereby a programme of study or an institution is
recognized by an external body as meeting certain predetermined standards.
Accreditation is often carried out by organizations created for the purpose of
assuring the public of the quality of the accredited institution or programme. The
state or federal governments can recognize accreditation in lieu of, or as the basis
for licensure or other mandatory approvals. Public or private payment
programmes often require accreditation as a condition of payment for covered
services. Accreditation may either be permanent or may be given for a specified
period of time.
See also “licence”.
accreditation standard A standard against which facilities or programmes are
evaluated to determine if they will be accredited.
administrative costs Costs which are not attributable to the direct delivery of
health services and are not direct clinical care or service costs.
administrative record A record concerned with administrative matters, such as
length of stay, details of accommodation, or billing.
admitting privileges The authorization given by a health care organization’s
governing body to medical practitioners and, in some cases, other professionals
who request the privilege of admitting and/or treating patients. Privileges are
based on a provider’s licence, training, experience and education.
affiliation An agreement (usually formal) between two or more otherwise
independent entities or individuals, or an individual and an entity, which defines
how they will relate to each other.
all payer system A system in which prices for health services and payment
methods are the same, regardless of who is paying. For instance, in an all payer
system, federal or state government, a private insurer, a self-insured employer
plan, an individual, or any other payer could pay the same rates. The uniform fee
bars health care providers from shifting costs from one payer to another.
See “cost shifting”.
allocative tool A means by which resources are allocated, which may be used in a
number of ways. For example, an allocative tool may be a health policy in which
there is a direct provision of income, services, or goods to groups of individuals
who usually reap benefits in receiving them.
allowance 1 A sum granted as reimbursement for expenses. 2 An amount added
or deducted on the basis of qualifying circumstances.
amortization The act or process of retiring a debt, usually by equal payments at
regular intervals over a specific period of time.

resources such as clinicians and facilities and patients. It is used in order to
minimize waiting times, prioritize appointments and optimize the utilization of
resources.
appraisal The process of assessing the level of subsidy to be paid for a resident on
the basis of his or her relative care needs.
average cost See “cost”.
average daily census The average number of hospital beds occupied per day.
This measure provides an estimate of the number of inpatients receiving care
each day at a hospital.
average length of stay (ALOS) A measure of how many days a patient, on
average, spends in the hospital. Hence, this measure, when applied to
individuals or specific groups of patients, may be an indicator of the severity of
illness and resource use. It is often used as a comparison to assess efficiency of
resource usage between hospitals.
avoided cost See “cost”.
B
balance billing The practice of medical practitioners, dentists and other
independent practitioners to seek payment from the patient for that portion of the
patient’s bill not covered by the government or other third party payers.

budgeted amounts and the regulations for spending them.
C
capital Fixed or durable non-labour inputs or factors used in the production of
goods and services, the value of such factors, or the money specifically allocated
for their acquisition or development. Capital costs include, for example, the
buildings, beds and equipment used in the provision of hospital services. Capital
assets are usually thought of as permanent and durable, as distinguished from
consumables, such as supplies.
58

capital depreciation The decline in value of capital assets (assets of a permanent
or fixed nature, such as goods and plant) with use over time. The rate and
amount of depreciation is calculated by a variety of different methods (e.g.
straight line, sum of the digits, declining balance), which often give quite different
results.
capital expenditure Expenditure for the acquisition, replacement, modernization or
expansion of facilities or equipment which, under generally accepted accounting
principles, is not properly chargeable as an expense of operation and
maintenance.
capitation A method of payment for health care services in which an individual or
institutional provider is paid a fixed amount for each person served in a set period
of time, without regard to the actual number or nature of services provided to
each person.
care supply The types and volumes of services available.
carrier An insurer; an underwriter of risk, who finances health care. Also refers to
any organization which underwrites or administers life, health or other insurance
programmes.
case payment Fixed cost for a case.
See also “fee for service”.
catastrophic health insurance Health insurance which provides protection against
the high cost of treating severe or lengthy illnesses or disabilities. Generally such
policies cover all, or a specified percentage of medical expenses above an
amount that is the responsibility of another insurance policy, up to a maximum
limit of liability.
certification The process by which a government or nongovernmental agency or
association evaluates and recognizes an individual, institution or educational
programme as meeting predetermined standards. One so recognized is said to
be “certified”. It is essentially synonymous with accreditation, except that
certification is usually applied to individuals and accreditation to institutions.
Certification programmes are generally nongovernmental and do not exclude the
uncertified from practice, as do licensure programmes.
charge In health care, a charge is the monetary amount that is billed to the user of
a product or service by the provider.
co-insurance A cost-sharing requirement under a health insurance policy. It
provides that the insured party will assume a portion or percentage of the costs of
covered services.
commercial insurance In health care, usually any insurance for hospital or medical
care which has the objective of making a profit.
commissioning The process of drawing up contracts with service providers to
provide care.
community rating A method for the determination of health insurance premiums
that spreads the risk among members of a large community and establishes
premiums based on the utilization experience of the whole community. For a set
of benefits, the same rate applies to everyone regardless of age, gender,
occupation or any other indicator of health risk.
59

consolidation A concentration of control by a few organizations over other existing
organizations through consolidation of facility assets that already exist.
Acquisitions, mergers, alliances and formation of contractual networks are
examples of consolidation.
co-payment The specified portion (cost amount or percentage) that health
insurance, or a service programme, may require a person to pay towards his or
her medical bills or services.
cost Actual expenses incurred to provide a health care product or service. Cost
can be divided into a number of types including:
average cost: The average cost per unit; equals the total cost divided by the
units of production.
avoided cost: Cost caused by a health problem that is avoided by a health care
intervention.
direct cost: Cost borne by the health care system, the community and families,
e.g. diagnosis and treatment costs. A cost that is identifiable directly with a
particular activity, service or product.
fixed cost: Costs that, within a defined period, do not vary with the quantity
produced, e.g. overhead costs of maintaining a building.
incremental cost: The difference between marginal costs of alternative
interventions.
indirect cost: Cost which cannot be identified directly with a particular activity,
service or product of the programme experiencing the cost. Indirect costs are
usually apportioned among the programme's services in proportion to each
service's share of direct costs.
intangible cost: The cost of pain and suffering resulting from a disease, condition
or intervention.
marginal cost: The additional cost required to produce an additional unit of
benefit (e.g. unit of health outcome).
operating cost: In the health field, the financial requirements necessary to
operate an activity that provides health services. These costs normally include
costs of personnel, materials, overheads, depreciation and interest.
opportunity cost: The benefit foregone, or value of opportunities lost, by
engaging resources in a service. It is usually quantified by considering the benefit
that would accrue by investing the same resources in the best alternative manner.
recurrent cost: An item of expenditure that recurs year after year, such as the
remuneration of health workers and other staff; the cost of food and other goods
and services; the cost of vaccines, medicines, appliances and other supplies; the
replacement of equipment; and the maintenance of buildings and equipment.
tangible cost: Objective elements in the production of care, i.e. number of
personnel, beds, consumables, technologies, staff qualifications.
total cost: The sum of all costs incurred in producing a set quantity of service.
60

cost-benefit The relationship between the cost of an activity and the benefit that
accrues from it.
cost-benefit analysis The systematic comparison, in monetary terms, of all the
costs and benefits of proposed alternative schemes with a view to determining:
which scheme or combination of schemes will contribute most to the achievement
of predetermined objectives at a fixed level of investment; or the magnitude of the
benefit that can result from schemes requiring the minimum investment. The
resources required per unit of benefit must be determined, account being taken of
the fact that costs and benefits accrue with time. For example, the cost of
establishing a home and community care programme might be compared with the
total cost of building residential facilities. Cost-benefit analysis can also be
applied to specific medical tests and treatments.
cost centre An accounting device whereby all related costs attributable to some
“financial centre” within an organization, such as a department, centre or
programme, are segregated for accounting or reimbursement purposes.
cost containment A set of steps to control or reduce inefficiencies in the
consumption, allocation or production of health care services which contribute to
higher than necessary costs.

possible.
cost minimization analysis A determination of the least costly among alternative
interventions that are assumed to produce equivalent outcomes.
cost-of-illness analysis A determination of the economic impact of a disease or
health condition, including treatment costs.
cost-of-living adjustment (COLA) Increase to a monthly long-term disability
benefit, usually after the first year of payments. May be a flat percentage (e.g.
3%) or tied to changes in inflation.
cost outlier A case which is more costly to treat compared with other persons in a
particular diagnosis-related group. Outliers also refer to any unusual occurrence
of cost, cases which skew average costs or unusual procedures.
cost sharing Payment method whereby a person is required to pay some health
costs in order to receive medical care. The general set of financing arrangements
whereby the consumer must pay out-of-pocket to receive care, either at the time
of initiating care or during the provision of health care services, or both. Cost
sharing can also occur when an insured person pays a portion of the monthly
premium for health care insurance.
cost shifting Recouping the cost of providing uncompensated care by increasing
revenues from some payers to offset losses and lower net payments from other
payers.
costing Methods and processes for calculating costs (actual and estimated)
required to achieve certain goals, obtain certain products or carry out certain
processes, or for maintenance of the health service.
61

coverage The guarantee against specific losses provided under the terms of an
insurance policy. Coverage is sometimes used interchangeably with benefits or
protection, and is also used to mean insurance or insurance contract.
credentialing The recognition of professional or technical competence. The
credentialing process may include registration, certification, licensure,
professional association membership or the award of a degree in the field.
criterion An attribute or rule that serves as a basis for evaluation, definition or
classification of something; an evaluation standard.
D
deductible The amount of loss or expense that must be incurred by an insured
individual before an insurer will assume any liability for all or part of the remaining
cost of covered services. Deductibles may be either fixed monetary amounts or
the value of specified services (such as two days of hospital care or one medical
practitioner visit). Deductibles are usually tied to some reference period over
which they must be incurred.
diagnosis-related group A system used for payment under prospective payment
systems. It classifies treatments by diagnosis, measuring the relative complexity
of a hospital procedure and accounting for the resources used in the procedure.
The system accounts for principal diagnosis, secondary diagnosis, surgical
procedures, age, sex and presence of complications.
direct cost See “cost”.
E
economic evaluation A feasibility study which recognizes the interrelationship of
capital cost, recurrent cost, investment and return, and lifecycle costs for
individual facilities and services.
economy of care Costs are the measure of the economic function of care. Total
costs and unit costs are the basic indicators.
effective / effectiveness The degree to which a treatment plan, programme or
project has achieved its purpose within the limits set for reaching its objective.
For example, an expression of the desired effect of a programme, service or
institution in reducing a health problem or improving an unsatisfactory health
situation.

as possible, the relevance, effectiveness and impact of activities in the light of
their objectives. Several varieties of evaluation can be distinguished, e.g.
evaluation of structure, process and outcome.
experience rating A method of adjusting health plan premiums based on historical
utilization data.

F
fair financing Where members of society should pay the same share of their
disposal income to cover their health costs.
fee for service (FFS) Method of billing for health services under which a medical
practitioner or other practitioner charges separately for each patient encounter or
service rendered. Under a fee-for-service payment system, expenditures
increase if the fees themselves increase, if more units of service are provided, or
if more expensive services are substituted for less expensive ones. This system
contrasts with salary, per capita, or other prepayment systems, where the
payment to the medical practitioner is not changed according to the number of
services actually used.
fee schedule A listing of accepted fees or established allowances for specified
medical or other professional procedures and services. As used in medical care
plans, it usually represents the maximum amounts the programme will pay for the
specified procedures.

produced in a country. It is an indicator of total economic production.
general liability insurance Insurance which covers the risk of loss for most
accidents and injuries to third parties (the insured and its employees are not
covered) which arise from the actions or negligence of the insured, and for which
the insured may have legal liability, except those injuries directly related to the
provision of professional health care services (the latter risks are covered by
professional liability insurance).

disease or accidental bodily injury. Such insurance usually covers all or part of
the costs of treating the disease or injury. Insurance may be obtained on either
an individual or a group basis.
horizontal integration Merging of two or more firms at the same level of production
in some formal, legal relationship. In hospital networks, this may refer to the
grouping of several hospitals, the grouping of outpatient clinics with the hospital,
or a geographic network of various health care services. Integrated systems seek
to integrate both vertically with some organizations and horizontally with others.
See “vertical integration”.
I
incremental cost See “cost”.
indemnity Health insurance benefits provided in the form of cash payments rather
than services. An indemnity insurance contract usually defines the maximum
amounts which will be paid for covered services.

expenses actually incurred.
indirect cost See “cost”.
internal benchmark See “benchmark”.
inventory A list of quantities and locations of different kinds of facilities, major

determines what levels should be maintained, replaced and ordered.
L
licence/licensure A permission granted to an individual or organization by a
competent authority, usually public, to engage lawfully in a practice, occupation or
activity. Licensure is the process by which the licence is granted. It is usually
granted on the basis of examination and/or proof of education rather than on
measures of performance. A licence is usually permanent, but may be
conditional on annual payment of a fee, proof of continuing education, or proof of
competence.
See also “accreditation”.
life insurance Insurance providing for payment of a stipulated sum to a designated
beneficiary upon death of the insured.

revenue-producing operations of the entity, but which are not directly attributable
to a single activity. For example, overhead costs normally include maintenance of
plant, occupancy costs, housekeeping, administration and others.
P
per diem Reimbursement where payment is based on a per day set fee schedule.
planning ratio Service provision targets established by an authority on a population
basis.
portability Requirement in benefit plans that allow benefit rights to be transferred
without waiting periods for persons moving between plans, regions or countries.

policy holder to an insurer or third party payer for insurance coverage under an
insurance policy. Premiums are paid for coverage whether benefits are used or
not.
prepayment Fee paid by a potential consumer of services in anticipation of
services that may be required.
prior authorization A requirement imposed by a third party payer under many
systems of utilization review in which a provider must justify, before a peer review
committee, insurance company representative or state agent, the need to deliver
a particular service to a person before actually providing the service in order to
receive reimbursement.

professional liability Insurance Liability insurance to protect professionals for loss
or expense resulting from claims arising from mistakes, errors or omissions
committed or alleged to have been committed by the insured in his professional
activities.
programme budgeting The process of making resources available to attain the
objectives of programmes. Programme budgeting differs from ordinary budgeting
in that the emphasis is on the results to be achieved rather than on unconnected
budgetary items. The objectives and targets of the programme are defined
clearly and, in order to attain them, the resources required are grouped together,
those who will receive them specified, and their sources determined.
programme evaluation / review The systematic assessment of the relevance,
adequacy, progress, efficiency, effectiveness and impact of a programme.
programme management A system of management which involves the integration
of planning, resourcing and evaluation processes to achieve stated outcomes.
prospective payment system A system whereby reimbursement rates are set for
a given period of time prior to the circumstances giving rise to actual
reimbursement claims.
Q
quality assessment and performance improvement programme (QAPI) QAPI
establishes strategies for promoting high quality health care. First, each
organization must meet certain required levels of performance when providing
specific health care and related services. Second, organizations must conduct
performance improvement projects that are outcome-oriented and that achieve
demonstrable and sustained improvement in care and services. It is expected
that an organization will continuously monitor its own performance on a variety of
dimensions of care and services, identify its own areas for potential improvement,
carry out individual projects to undertake system interventions to improve care,
and monitor the effectiveness of those interventions.
66

quality assurance (QA) Standardized procedures, methods or philosophy for
collecting, processing or analysing data, which is performed on an ongoing basis
and aimed at maintaining or improving the appropriateness and reliability of
health care services.
quality circle An instrument for quality enhancement and quality assurance which
uses groups of peers to assess and discuss the quality of their own work and
develop strategies for improvement.
quality control (QC) The sum of all the activities which prevent unwanted change
in quality. In the health care setting, quality control requires a repeated series of
feedback loops which monitor and evaluate the care of the individual (and other
elements in the health care process). These feedback loops involve checking the
care being delivered against standards of care, identification of any problems or
opportunities for improvement, and prompt corrective action, so that the quality is
maintained.
quality improvement / continuous quality improvement The sum of all the
activities which create desired change in quality. In the health care setting,
quality improvement requires a feedback loop which involves the identification of
patterns of the care of individuals (or of the performance of other systems
involved in care), the analysis of those patterns in order to identify opportunities
for improvement (or instances of departure from standards of care), and then
action to improve the quality of care for future patients. An effective quality
improvement system results in step-by-step increases in quality of care.
quality of basic amenities The quality of non-clinical attributes of health care units,
such as cleanliness of the facility, adequacy of the furniture and quality of the
food.
quality of care The degree to which delivered health services meet established
professional standards and are judged to be of value to the consumer. Quality
may also be seen as the degree to which actions taken or not taken maximize the
probability of beneficial health outcomes and minimize risk and other outcomes,
given the existing state of medical science and art.
R
rate review Review by a government or private agency of a hospital’s or health
service’s budget and financial data, performed for the purpose of determining if
the rates are reasonable of the rates and evaluating proposed rate increases.
rate setting A method of paying health care providers in which the government
establishes payment rates for all payers for various categories of health service.
readmission The re-entry of a person to a hospital or other health facility within a
specified interval after discharge with the same diagnosis.
readmission rate The proportion of a hospital’s patients (or a subset, such as
those with asthma) who are readmitted to the hospital following discharge with the
same diagnosis. It is used as a performance measure where a higher rate
indicates lower quality of care.
recurrent cost See “cost”.
67

reimbursement 1 The process by which health care providers receive payment for
their services. Because of the nature of the health care environment, providers
are often reimbursed by third parties who insure and represent patients/clients.
2 The process whereby patients/clients receive payment for services used, most
often through health insurance.
reinsurance A mechanism whereby an insurer can cover high-risk losses through
insurance from another insurer.
resident classification instrument An instrument which assesses recipient's care
needs. It has a number of classification levels, ranging from high to low care.
These classification levels are sometimes used for placement, staffing level and
reimbursement purposes.
resource management The process of trying to attain the most rational use of
manpower, knowledge, facilities and funds to achieve the intended purposes with
the greatest effect with the least outlay.
revenue The gross amount of earnings received by an entity for the operation of a
specific activity. It does not include any deductions for such items as expenses,
bad debts or contractual allowances.
risk approach An approach consisting of identifying and devoting more care to
individuals or groups who, for biological, environmental or socioeconomic reasons,
are at special risk of having their health impaired, contracting a specific disease,
or having inadequate attention paid to their health problems.
risk assessment The qualitative or quantitative estimation of the likelihood of
adverse effects that may result from exposure to specified health hazards or from
the absence of beneficial influences.
risk management The function of identifying and assessing problems that could
occur and bring about losses legally, clinically or financially.
risk pooling The practice of bringing several risks together for insurance purposes
in order to balance the consequences of the realization of each individual risk.
risk rating Risk rating means that high-risk individuals will pay more than the
average premium price.
risk selection The practice of singling out or disaggregating a particular risk from a
pool of insured risks.
risk sharing The distribution of financial risk among parties furnishing a service.
For example, if a hospital and a group of medical practitioners form a corporation
to provide health care at a fixed price, a risk-sharing arrangement would entail
both the hospital and the group being held liable if expenses were to exceed
revenues.
root-cause analysis A process for identifying the basic or causal factor(s) that
underlie variations in performance, including the occurrence or possible
occurrence of an error.
S
subscriber See “enrollee”.
68

T
total quality management (TQM) TQM is synonymous with continuous quality
improvement (CQI). It is an integrative management concept of continuously
improving the quality of delivered goods and services through the participation of
all level and functions of the organization to meet the needs and expectations of
the customer.
treatment episode The period of treatment between admission and discharge from
a facility, such as inpatient, residential, partial hospitalization and outpatient, or
the period of time between the first procedure and last procedure on an outpatient
basis for a given diagnosis. Many health care statistics and profiles use this unit
as a base for comparisons.
trending Method of estimating future costs of health services by reviewing past
trends in cost and utilization of those services.
U
underwriting In insurance, the process of selecting, classifying, evaluating and
assuming risks according to their insurability. Its purpose is to make sure that the
insured group or individual has the same probability of loss and probable amount
of loss, within reasonable limits, as the universe on which premium rates are
based. Since premium rates are based on an expectation of loss, the
underwriting process must classify risks into groups with about the same
expectation of loss.
utilization Use of services and supplies. Utilization is commonly examined in terms
of patterns or rates of use of a single service or type of service, such as hospital
care, medical practitioner visits or prescription drugs. Measurement of utilization
of all medical services in combination is usually done in terms of economic costs.
Use is expressed in rates per unit of population at risk for a given period, such as
the number of admissions to hospital per 1000 persons over age 65 per year, or
the number of visits to a medical practitioner per person per year.
utilization review Evaluation of the necessity, appropriateness and efficiency of the
use of health care services, procedures and facilities. In a hospital, this includes
review of the appropriateness of admissions, services ordered and provided,
length of a stay, and discharge practices, both on a concurrent and retrospective
basis. Utilization review can be done by a peer review group or a public agency.
V
vertical integration The organization of production whereby one entity controls or
owns all stages of the production and distribution of goods or services. In health
care, vertical integration can take many forms, but generally implies that medical
practitioners, hospitals and health plans have combined their organizations or
processes in some manner to increase efficiencies, increase competitive strength,
or improve quality of care. Integrated delivery systems or health care networks
are generally vertically integrated.
See “horizontal integration”.
69

W
working capital The sum of the institution’s short-term or current assets, including
cash, marketable (short-term) securities, accounts receivable and inventories.

great variation (i.e. not close in magnitude to each other).
action research A family of research methodologies which pursue action (or
change) and research (or understanding) at the same time.
alpha (α) error See “Type I error”.
alpha (α) statistic A statistic commonly used to reflect the reliability of a
measurement scale.
See “reliability”.
analytic study A study designed to examine associations, commonly putative or
hypothesized causal relationships. An analytic study is usually concerned with
identifying or measuring the effect of risk factors, or is concerned with the health
effects of specific exposure(s).
anecdotal evidence Evidence derived from descriptions of cases or events rather
than systematically collected data that can be submitted to statistical tests.
arithmetic mean See “mean”.
association A term signifying a relationship between two or more events or
variables. Events are said to be associated when they occur more frequently
together than one would expect by chance. Association does not necessarily
imply a causal relationship. Statistical significance testing enables a researcher
to determine the likelihood of observing the sample relationship by chance if in
fact no association exists in the population that was sampled. The terms
“association” and “relationship” are often used interchangeably.
attributable risk In a total population, the proportion of disease incidence, or risk of
the disease, that can be attributed to exposure to a specific risk factor; the
difference between the risk in the total population and the risk in the unexposed
group.
71

B
baseline An observation or value that represents the background level of a
measurable quantity.
beta (β) error See “Type II error”.
bias In general, any factor that distorts the true nature of an event or observation.
In clinical observations, a bias is any systematic factor other than the intervention
of interest that affects the magnitude of an observed difference (i.e. trends to
increase or decrease) in the outcomes of a treatment group and control group.
Bias diminishes the accuracy (though not necessarily the precision) of an
observation. Randomization is a technique used to decrease this form of bias.
Bias also refers to a prejudiced or partial viewpoint that would affect someone’s
interpretation of a problem. Double-blinding is a technique used to decrease this
type of bias.
See “blinding”.
bibliographic database An indexed computer or printed source of citations of
journal articles and other reports in the literature. Bibliographic citations typically
include author, title, source, abstract and/or related information (including full text
in some cases).
blinding The concealment of group assignment (to either the treatment or control
group) from the knowledge of participants and/or investigators in a clinical trial.
Blinding eliminates the possibility that knowledge of assignment may affect
individual response to treatment or investigator behaviours that may affect
outcomes. Blinding is not always practical (e.g. when comparing surgery to drug
treatment) but it should be used whenever it is possible and compatible with
optimal care. There are various kinds of blinding:
single-blind trial: one in which knowledge of group assignment is withheld only
from participants
double-blind trial: one in which the knowledge is withheld from participants and
investigators
triple-blind trial: one in which the knowledge is withheld from participants,
investigators and those assessing outcomes of the assignment.
C
case control study A study that starts with the identification of persons with the
disease (or other outcome variable) of interest, and a suitable control (comparison,
reference) group of persons without the disease. The relationship of an attribute
to the disease is examined by comparing the diseased and non-diseased with
regard to how frequently the attribute is present or, if quantitative, the level of the
attribute, in each of the groups.
case study An in-depth study of an individual, group, institution, organization or
programme. The advantage of the case study method is that it allows more
intensive analyses of specific empirical details. However, it is difficult to use the
results to generalize to other cases.
causality Relating causes to the effects they produce.
72

census The enumeration of an entire population, usually with details being
recorded on residence, age, sex, occupation, ethnic group, marital status, birth
history and relationship to head of household.
citation The record of an article, book or other report in a bibliographic database
that includes summary descriptive information, e.g. author, title, abstract, source
and indexing terms.
class The total number of observations of a particular variable may be grouped
according to convenient divisions of the variable range. A group so determined is
called a class.
class interval The difference between the lower and upper limits of a class.
classification Assignment to predesignated classes on the basis of perceived
common characteristics. A means of giving order to a group of disconnected
facts.
cluster An aggregation of cases of a disease or other health-related condition
which are closely grouped in time and place. The number of cases may or may
not exceed the expected number; frequently the expected number is not known.
cohort study An observational study in which outcomes in a group of participants
that received an intervention are compared with outcomes in a similar group (i.e.
the cohort) of participants, either contemporary or historical, that did not receive
the intervention. In an adjusted (or matched) cohort study, investigators identify
(or make statistical adjustments to provide) a cohort group that has characteristics
(e.g. age, gender, disease severity) that are as similar as possible to the group
that experienced the intervention.
concurrent nonrandomized control A control group that is observed by
investigators at the same time as the treatment group but that was not
established using random assignment of participants to control and treatment
groups. Differences in the composition of the treatment and control groups may
result.
confidence interval A range of values for a variable of interest, e.g. a rate,
constructed so that this range has a specified probability of including the true
value of the variable. The specified probability is called the confidence level, and
the end points of the confidence interval are called the confidence limits.
confidence limit The minimum and maximum value of a confidence interval.
confounding variable A variable or fact that confuses a result. A confounder
distorts the ability to attribute cause to a treatment, for example, because it is
likely something else is confusing the result.
consensus development Various forms of group judgement in which a group (or
panel) of experts interacts in assessing an intervention and formulating findings
by vote or other process of reaching an agreement. These processes may be
informal or formal, involving such techniques as the nominal group and Delphi
techniques.
73

consent The granting of permission, agreement, assent or approval. In any
research on human beings, each potential subject must be adequately informed
of the aims, methods, sources of funding, any possible conflicts of interest,
institutional affiliations of the researcher, the anticipated benefits and potential
risks of the study, and the discomfort it may entail. The subject should be
informed of the right to abstain from participation in the study or to withdraw
consent to participate at any time without reprisal. After ensuring the subject has
understood the information, the researcher should then obtain the subject’s freely
given informed consent, preferably in writing. If the consent cannot be obtained in
writing, the non-written consent must be formally documented and witnessed.
construct validity See “validity”.
contamination Occurs when the treatment assigned to people in one study group
is also used by some or all members of another group.
content analysis A systematic analysis of the content rather than the structure of a
communication, such as a written work, speech or film, including the study of
thematic and symbolic elements to determine the objective or meaning of the
communication.
content validity See “validity”.
continuous data (variable) See “data”.
control group A group of participants that serves as the basis of comparison when
assessing the effects of the intervention of interest that is given to the participants
in the treatment group. Depending upon the circumstances of the trial, a control
group may receive no treatment, a ‘usual’ or ‘standard’ treatment, or a placebo.
To make the comparison valid, the composition of the control group should
resemble that of the treatment group as closely as possible.
convenience sample A population being studied because they are conveniently
accessible (for example, all the people at a certain hospital or attending a
particular support centre). As they are not a random sample of the whole
population, they may be unrepresentative.
correlation Most generally, the degree to which one phenomenon or random
variable is associated with, or can be predicted from, another. In statistics,
correlation usually refers to the degree to which a linear predictive relationship
exists between random variables, as measured by a correlation coefficient (q.v.).
Correlation may be positive (but never larger than 1), i.e. both variables increase
or decrease together; negative or inverse (but never smaller than -1), i.e. one
variable increases when the other decreases; or zero, i.e. a change in one
variable does not affect the other.
criterion validity See “validity”.
critical appraisal The process of assessing and interpreting evidence by
systematically considering its validity, results and relevance.
crossover bias Occurs when some participants who are assigned to the treatment
group in a clinical study do not receive the intervention or receive another
intervention, or when some participants in the control group receive the
intervention (e.g. outside the trial). If these crossover participants are analysed
with their original groups, this type of bias can “dilute” (diminish) the observed
treatment effect.
74

crossover trial A trial in which each of the groups involved will receive each of the
treatments, but in a randomized order: that is, they will start in one arm of the trial,
but will deliberately ‘cross over’ to the other arm(s) in turn.
cross-sectional study A study that measures the prevalence of health outcomes
or determinants of health, or both and other variables of interest in a population at
a point in time or over a short period.
cross-utility analysis A form of cost-effectiveness analysis of alternative
interventions in which costs are measured in monetary units and outcomes are
measured in terms of their utility, usually to the individual, e.g. using QALYs.
D
data Items of information.
continuous data: Data with a potentially infinite number of possible values along
a continuum (e.g. height, weight).
discrete data: Data that can be arranged into naturally occurring or arbitrarily
groups or sets of values.
individual data: Data that have not been put into a frequency distribution or rank
ordered.
database (or register) Any of a wide variety of repositories (often computerized) for
observations and related information about a group of individuals, a disease, an
intervention or other events or characteristics, typically organized for easy search
and retrieval.
death rate The proportion of deaths in a specified population. The death rate is
calculated by dividing the number of deaths in a population in a year by the
midyear resident population. Death rates are often expressed as the number of
deaths per 100 000 persons. The rate may be restricted to deaths in specific age,
race, sex, or geographic groups or deaths from specific causes of death (specific
rate), or it may be related to the entire population (crude rate).
Delphi technique An iterative group judgment technique in which a central source
forwards surveys or questionnaires to isolated, anonymous (to each other)
participants whose responses are collated/summarized and recirculated to the
participants in multiple rounds for further modification/critique, producing a final
group response (sometimes statistical).
denominator 1 The lower portion of a fraction used to calculate a rate or ratio. In a
rate, the denominator is usually the population at risk. 2 For a performance
measure, the sample of cases that will be observed (e.g. the number of patients
discharged alive with a confirmed diagnosis of acute myocardial infarction,
excluding patients with bleeding or other specified conditions).
See “numerator”.
dependent variable In a statistical analysis, the outcome variable(s) or the
variable(s) whose values are a function of, or dependent on the effect of other
variable(s) (called independent variables) in the relationship under study.
descriptive study A study concerned with and designed only to describe the
existing distribution of variables, without regard to causal or other hypotheses.
75

determinant Any factor, whether event, characteristic or other definable entity, that
brings about change in a health condition or other defined characteristic.
dichotomous scale See “measurement scale”.
discrete data See “data”.
discussion In a research paper/study, a discussion connects the various aspects of
the data analysis, shows the commonality across groups, uniqueness,
inconsistencies, etc., and identifies the limits to the study resulting from the
design and data analysis.
distribution The frequency and pattern of health-related characteristics and events
in a population.
double-blind trial See “blinding”.
E
economic evaluation A feasibility study which recognizes the interrelationship of
capital cost, recurrent cost, investment and return, and life-cycle costs for
individual facilities and services.
eligibility criteria An explicit statement of the conditions under which persons are
admitted to a study.
empirical Based directly on experience, e.g. observation or experiment, rather than
on reasoning alone.
empirical methods Research based on critical evaluation through observation or
experimentation, not opinion or speculation.
endpoint A measure or indicator chosen to determine an effect of an intervention.
ethnographic research The collection of extensive narrative data on many
variables over an extended period of time in a naturalistic setting in order to gain
insights not possible using other types of research. For this type of research,
observations are undertaken at particular points of time. Data would include
observations, recordings and interpretations of what is seen.
experimental study A study in which conditions are under the direct control of the
investigator.
explanatory study A study where the main objective is to explain, rather than
merely describe, a situation by isolating the effects of specific variables and
understanding the mechanisms of action.
external validity See “validity”.
F
face validity See “validity”.
factual database An indexed computer or printed source that provides information
in the form of guidelines for diagnosis and treatment, patient indications, or other
authoritative information. Examples are PDQ, a computer database on cancer
management, and DRUGLINE, a computer database on drug indications,
contraindications and interactions.
76

feasibility study Preliminary study to determine the practicability of a proposed
health programme or procedure, or of a larger study, and to appraise the factors
that may influence its practicability.
focus group A type of group discussion that is designed to elicit information about
the wants, needs, viewpoints, beliefs and experiences of the intended audience.
Focus groups can aid in better understanding the expressions and terminology
commonly used by people in the audience, as well as their attitudes and beliefs
about health care. They are useful for helping uncover the reasons behind
people’s responses.
follow-up study A study in which individuals or populations, selected on the basis
of whether they have been exposed to risk, have received a specified preventive
or therapeutic procedure, or possess a certain characteristic, are followed to
assess the outcome of exposure, the procedure or the effect of the characteristic,
e.g. occurrence of disease.
frequency See “occurrence”.
frequency distribution A complete summary of the frequencies of the values or
categories of a variable. Often displayed in a two-column table: the left column
lists the individual values or categories, the right column indicates the number of
observations in each category.
G
graph A way to show quantitative data visually, using a system of coordinates.
H
handsearching Looking for articles, not by searching electronic databases, but by
systematically going through journals.
health research Research on all aspects of health, the factors affecting it, and
ways of promoting, protecting and improving it. It is an essential part of national
health development. It includes medical and biomedical research relating to a
wide variety of medical matters and involving various life sciences, such as
molecular biology and biophysics; clinical research, which is based on the
observation and treatment of patients or volunteers; epidemiological research,
which is concerned with the study and control of diseases and of situations that
are suspected of being harmful to health; and socioeconomic and behavioural
research, which investigates the social, economic, psychological and cultural
determinants of health and disease with a view to promoting health and
preventing disease. Often a multidisciplinary combination of the above kinds of
research is needed to solve a health problem.
health services research The multidisciplinary field of scientific investigation that
studies how social factors, financing systems, organizational structures and
processes, health technologies, and personal behaviours affect access to health
care, the quality and cost of health care, and ultimately health and well-being. Its
research domains are individuals, families, organizations, institutions,
communities and populations.
health survey A survey designed to provide information on the health status of a
population. It may be descriptive, exploratory or explanatory.
77

health systems research Research dealing with the entire health system or only
part of it, the object being to ensure that the system is optimally planned and
organized and that programmes are carried out by the health system
infrastructure efficiently and effectively and with appropriate technology.
histogram A graphic representation of the frequency distribution of a variable.
Rectangles are drawn in such a way that their bases lie on a linear scale,
representing different intervals, and their heights are proportional to the
frequencies of the values within each of the intervals.
human-factor research The study of the interrelationships between humans, the
tools they use, and the environment in which they live and work.
hypothesis A supposition that appears to explain a group of phenomena and is
advanced as a basis for further investigation; a proposition that is subject to proof
or to an experimental or statistical test. Studies are often framed to test a ‘null’
hypothesis (for example “subjects will experience no change in blood pressure as
a result of administration of a test product”) to rule out every possibility except the
one the researcher is trying to prove, an assumption about a research population
that may or may not be rejected as a result of testing. A null hypothesis is used
because most statistical methods are less able to prove something true than to
provide strong evidence it is false.
See also “theory”; “null hypothesis”.
I
incidence The number of cases of disease, infection or some other event having
their onset during a prescribed period of time. It is often expressed as a rate (for
example, the incidence of cardiovascular disease per 1000 population aged 65-74
years during a specified year). Incidence is a measure of morbidity or other
events that occur within a specified period of time.
See also “prevalence”.
independence In statistical terms, two events are said to be independent if the
occurrence of one is in no way predictable from the occurrence of the other.
Independence is the antonym of association.
independent variable A variable that precedes, influences or predicts the
dependent variable.
index In epidemiology and related sciences, this word usually means a rating scale,
e.g. a set of numbers derived from a series of observations of specified variables.
indicator A variable, with characteristics of quality, quantity and time, used to
measure, directly or indirectly, changes in a situation and to appreciate the
progress made in addressing it. It also provides a basis for developing adequate
plans for improvement. It is a variable that helps to measure changes in a health
situation directly or indirectly and to assess the extent to which the objectives and
targets of a programme are being attained.
individual data See “data”.
inference The process of passing from observations and axioms to generalizations.
In statistics, the development of generalizations from sample data, usually with
calculated degrees of uncertainty.
integrative study See “synthetic study”.
78

internal validity See “validity”.
interquartile range The central portion of a distribution, calculated as the difference
between the third quartile and the first quartile; this range includes about one half
of the observations in the set, leaving one quarter of the observations on each
side.
interval scale See “measurement scale”.
interview schedule The precisely designed set of questions used in an interview.
K
key informant A person chosen to answer a survey on the grounds of a better
knowledge and understanding of the issues under consideration.
knowledge Knowledge may be regarded as the distillation of information that has
been collected, classified, organized, integrated, abstracted and value added.
Knowledge is at a level of abstraction higher than the data and information on
which it is based and can be used to deduce new information and new knowledge.
When considering knowledge, it is usually within the context of human expertise
used in solving problems.
L
length of stay (LOS) The number of days between a patient's admission and
discharge. This abbreviation is often misused when the intent is to refer to
average length of stay (ALOS).
Likert scale An ordinal scale of responses to a question or statement ordered in a
hierarchical sequence, such as from “strongly agree” through “no opinion” to
“strongly disagree”.
literature review A summary and interpretation of research findings reported in the
literature. It may include unstructured qualitative reviews by single authors as
well as various systematic and quantitative procedures, such as meta-analysis.
M
mean, arithmetric A measure of central tendency. The sum of all the values in a
set of measurements divided by the number of values in the set.
mean, geometric A measure of central tendency. The average of a set of data
measured on a logarithmic scale.
measurement The procedure of applying a standard scale to a variable or to a set
of values.
79

measurement scale The complete range of possible values for a measurement
(e.g. the set of possible responses to a question, the physically possible range for
a set of body weights). Measurement scales are sometimes classified into five
major types, according to the quantitative character of the scale:
dichotomous scale: One that arranges items into either of two mutually
exclusive categories.
nominal scale: Classification into unordered qualitative categories, such as race,
religion, and country of birth, as measurements of individual attributes are purely
nominal scales, as there is no inherent order to their categories.
ordinal scale: Classification into ordered qualitative categories, such as social
class, where the values have a distinct order, but their categories are qualitative
in that there is no natural (numerical) distance between their possible values.
interval scale: An (equal) interval involving assignment of values with a natural
distance between them, so that a particular distance (interval) between two
values in one region of the scale meaningfully represents the same distance
between two values in another region of the scale. An example is date of birth.
ratio scale: A ratio is an interval scale with a true zero point, so that ratios
between values are meaningfully defined. Examples are weight, height, blood
count and income, as in each case it is meaningful to speak of one value as being
so many times greater or less than another.
median A measure of central tendency. The median is found by arranging the
values in order and then selecting the one in the middle. If the total number of
values is even, then the median is the mean of the two middle numbers. The
median is useful where the distribution has extreme values which otherwise skew
the data.
meta-analysis A statistical procedure to combine results from different studies on a
similar topic. The combination of results from multiple studies may produce a
stronger conclusion than can be provided by any singular study. Meta-analysis is
generally most appropriate when there are no definitive studies on a topic and
non-definitive studies are in some disagreement.
methodology The scientific study of methods.
midrange The halfway point or midpoint in a set of observations. For most types of
data, it is calculated as the sum of the smallest observation and the largest
observation, divided by two. For age data, one is added to the numerator. The
midrange is usually calculated as an intermediate step in determining other
measures.
missing data Information not available for a subject (or case) about whom other
information is available.
mode A measure of central tendency. The most frequently occurring value in a set
of observations.
mortality rate See “death rate”.
multivariate analysis A set of techniques used when the variation in several
variables has to be studied simultaneously. In statistics, any analytic method that
allows the simultaneous study of two or more independent variables.
80

N
nominal group technique A face-to-face group judgement technique in which
participants generate silently, in writing, responses to a given question/problem;
responses are collected and posted, but not identified by author, for all to see;
responses are openly clarified, often in a round robin format; further iterations
may follow; and a final set of responses is established by voting/ranking.
nominal scale See “measurement scale”.
nonparametric statistics Statistical techniques designed to be used when the data
being analysed depart from the distribution that can be analysed with parametric
statistics.
normal curve A bell shaped curve that results when a normal distribution is
graphed.
normal distribution The symmetrical clustering of values around a central location.
The properties of a normal distribution include: (1) it is a continuous, symmetrical
distribution: both tails extend to infinity; (2) the arithmetic mean, mode and
median are identical; and (3) its shape is completely determined by the mean and
standard deviation.
null hypothesis The statistical hypothesis that one variable has no association with
another variable or set of variables, or that two or more population distributions do
not differ from one another. In simplest terms, the null hypothesis states that the
results observed in a study, experiment or test are no different from what might
have occurred by chance alone.
numerator 1 The upper portion of a fraction used to calculate a rate or ratio. 2 For
a performance measure, the cases in the denominator group that experience
events specified in a review criterion.
See “denominator”.
O
observational study A study in which the investigators do not manipulate the use
of an intervention (e.g. do not randomize people to treatment and control groups)
but only observe people who are (and sometimes people who are not) exposed to
the intervention, and interpret the results.
occupancy rate A measure of the use of facilities, most often inpatient health
facility use, determined by dividing the number of patient days by the number of
bed days (or places) available, on average, per unit of time, multiplied by 100.
occurrence In epidemiology, a general term describing the frequency of a disease
or other attribute or event in a population, without distinguishing between
incidence and prevalence.
odds ratio 1 A measure of association which quantifies the relationship between an
exposure and outcome from a comparative study; also known as the cross-
product ratio. 2 Comparison of the presence of a risk factor in a sample.
ordinal scale See “measurement scale”.
outcome A possible result that may stem from exposure to a causal factor, or from
preventive or therapeutic interventions.
81

outcome research Research on measures of changes in outcomes, that is, health
status and satisfaction, resulting from specific interventions.
outlier Observation differing widely from the rest of the data.
P
parametric statistics Statistical techniques designed for use when data have
certain characteristics.
P value See “probability”.
parity Data parity is a term used by researchers to describe the degree to which
different data measures are equivalent.
participant observation A qualitative data collection technique in which the
researcher participates in activities in a setting to observe and record (or simply
study) actors' behaviour. Not all participant observation requires the researcher
to conceal his/her identity (thus participate as a member of the group).
participatory research A process in which the researcher facilitates analysis by a
range of stakeholder groups of the themes being investigated.
patient-origin study A study, generally undertaken by an individual health
programme or health planning agency to determine the geographic distribution of
the residences of the patients served by one or more health programmes. Such
studies help define catchment and medical trade areas and are useful in locating
and planning the development of new services.
peer review (in research) The process by which manuscripts submitted to a
publisher or research applications are evaluated by experts in appropriate fields
(usually anonymous to the authors) to ensure quality.
percentage The proportion multiplied by 100.
See “proportion”.
percentile The set of numbers from 0 to 100 that divide a distribution into 100 parts
of equal area, or divide a set of ranked data into 100 class intervals, with each
interval containing 1/100 of the observations. For example, the 5th
percentile, is a
cut point with 5% of the observations below it and the remaining 95% of the
observations above it.
pilot study A small-scale test of the methods and procedures to be used on a
larger scale if the pilot study demonstrates that these methods and procedures
can work.
population pyramid A graphic presentation of the age and sex composition of the
population.
precision 1 The quality of being sharply defined or stated. One measure of
precision is the number of distinguishable alternatives from which a measurement
was selected, sometimes indicated by the number of significant digits in the
measurement. Another measure of precision is the standard error of
measurement, the standard deviation of a series of replicate determinations of the
same quantity. Precision does not imply accuracy. 2 In statistics, precision is
defined as the inverse of the variance of a measurement or estimate.
82

predictive value 1 The statistic generated by dividing the number of true positives
by the sum of the true positives and false positives. For example, the number of
cases with truly good care divided by the sum of the cases with truly good care
plus those cases classified with good care who did not receive it i.e. the likelihood
that a person classified as the recipient of good care actually received good care.
2 In screening and diagnostic tests, the probability that a person with a positive
test result is a true positive (i.e. does have the disease) is referred to as the
“predictive value of a positive test”. The predictive value of a negative test is the
probability that a person with a negative test does not have the condition or
disease. The predictive value of a screening test is determined by the sensitivity
and specificity of the test, and by the prevalence of the condition for which the
test is used.
prevalence The number of events, such as instances of a given disease, condition
or other attribute, present at a particular time. Sometimes used to mean
prevalence rate. When used without qualification, the term usually refers to the
situation at a specified point in time (point prevalence).
annual prevalence: The total number of persons with a given disease or attribute
at any time during a year.
lifetime prevalence: The total number of persons known to have had a given
disease or attribute for at least part of their lives.
period prevalence: The total number of persons known to have had a given
disease or attribute at any time during a specified period.
point prevalence: The total number of persons with a given disease or attribute
at a specified point in time.
See also “incidence”.
prevalence study See “cross-sectional study”.
primary study An investigation that collects original (primary) data from subjects,
e.g. randomized controlled trials, observational studies, series of cases, etc.
See “secondary data analysis”.
probability (P value) The likelihood that an event will occur. When looking at
differences between data samples, statistical techniques are used to determine if
the differences are likely to reflect real differences in the whole group from which
the sample is drawn, or if they are simply the result of random variation in the
samples. It is the probability that a test statistic would be as extreme as, or more
extreme than that observed if the null hypothesis were true. The letter P, followed
by the abbreviation n.s. (not significant) or by the symbol < (less than) and a
decimal notation such as 0.01, 0.05, is a statement of the probability that the
difference observed could have occurred by chance, if the groups are really alike,
i.e. under the null hypothesis. Although investigators may choose their own
significance levels in most studies, a result whose probability value is less than
5% (P<0.05) or 1% (P<0.01) is considered sufficiently unlikely to have occurred
by chance to justify the designation “statistically significant”. For example, a
probability (or P value) of 1% indicates that the differences observed would have
occurred by chance in one out of a hundred samples drawn from the same data.
proportion A number ranging between 0 and 0.1 calculated by dividing the number
of subjects having a certain characteristic by the total number of subjects.
See also “percentage”.
83

prospective study See “cohort study”.
publication bias Unrepresentative publication of research reports that is not due to
the quality of the research but to other characteristics, e.g. tendencies of
investigators to submit, and publishers to accept, positive research reports (i.e.
ones with results showing a beneficial treatment effect of a new intervention).
Q
qualitative research Involves the use of non-numerical data, such as those
collected in unstructured and in-depth interviews, focus group discussions,
participant observation, participatory research, and the study of documents.
quality-adjusted life years (QALYs) Years of life saved by a medical technology
or service, adjusted according to the quality of those years (as determined by
some evaluative measure). QALYs are the most commonly used unit to express
the results in some types of cost-effectiveness analysis.
quantitative research Involves the use of data in numerical quantities such as
continuous measurements or counts.
quartile Division of the total cases or observations in a study into four groups of
equal size.
questionnaire A predetermined set of questions used to collect data – clinical data,
socioeconomic status etc. The instrument is either administered by an
interviewer in an interview situation or is self-administered (by a subject).
R
random / random sample A sample that is arrived at by selecting sample units
such that each possible unit has a fixed and determined probability of selection.
random variation / random error The tendency for the estimated magnitude of a
parameter (e.g. based upon the average of a sample of observations of a
treatment or intervention effect) to deviate randomly from the true magnitude of
that parameter. Random variation is independent of the effects of systematic
biases. In general, the larger the sample size, the lower the random variation of
the estimate of a parameter. As random variation decreases, precision increases.
randomization A technique of assigning subjects to intervention and control groups
that is based only on chance distribution. It is used to diminish selection bias.
range In statistics, the difference between the largest and smallest values in a
distribution. In common use, the span of values from smallest to biggest.
rate A measure of the frequency of a phenomenon. In epidemiology, demography
and vital statistics, a rate is an expression of the frequency with which an event
occurs in a defined population. Rates are usually expressed using a standard
denominator such as 1000 or 100 000 persons. Rates may also be expressed as
percentages. The use of rates rather than raw numbers is essential for
comparison of experience between populations at different times or in different
places, or among different classes of persons.
ratio The value obtained by dividing one quantity by another: a general term of
which rate, proportion, percentage, etc. are subsets. A ratio is an expression of
the relationship between a numerator and a denominator where the two usually
are separate and distinct quantities, neither being included in the other.
84

ratio scale See “measurement scale”.
raw data The entire set of information that has been collected, before any cleaning,
editing or statistical manipulation begins.
reference population The base population from which a sample is drawn at the
time of initial sampling. The standard against which a population that is being
studied can be compared.
See “population”.
register See “database”.
regression analysis A tool to estimate the relationships among a dependent
variable Y and one (or many) independent variable(s) X. The purpose of
regression analysis is to find the “best fit” data points from a straight line drawn on
an XY graph.
relative risk The ratio of the risk of disease or death among the exposed to the risk
among the unexposed; this usage is synonymous with risk ratio.
reliability The degree of stability exhibited when a measurement is repeated under
identical conditions. Reliability refers to the degree to which the results obtained
by a measurement procedure can be replicated. Lack of reliability may arise from
divergences between observers or instruments of measurement, or instability of
the attribute being measured.
replication Research that attempts to reproduce the findings of previous
investigators so as to increase confidence in (or refute) those findings.
representative sample The term “representative”, as it is commonly used, is
undefined in the statistical or mathematical sense; it means simply that the
sample resembles the population in some way. The use of probability sampling
will not ensure that any single sample will be “representative” of the population in
all possible aspects. A common fallacy lies in the unwarranted assumption that, if
the sample resembles the population closely on those factors that have been
checked, it is “totally representative” and no differences exist between the sample
and the universal or reference population.
research design The procedures and methods, including ethical considerations,
predetermined by an investigator, to be adhered to in conducting a research
project.
response rate The number of completed or returned survey instruments
(questionnaires, interviews, etc) divided by the total number of persons who
would have been surveyed if all had participated. Usually expressed as a
percentage.
retrospective study A research design used to test hypotheses in which inferences
about exposure to the putative causal factor(s) are derived from data relating to
characteristics of the persons under study or to events or experiences in their
past. The essential feature is that some of the persons under study have the
disease or other outcome condition of interest, and their characteristics and past
experiences are compared with those of other, unaffected persons.
risk The probability that an event will occur.
85

risk-benefit analysis The process of analysing and comparing, on a single scale,
the expected positive (benefits) and negative (risks, costs) results of an action, or
lack of an action.
risk factor An aspect of personal behaviour or lifestyle, an environmental exposure,
or an inborn or inherited characteristic, which, on the basis of scientific evidence,
is known to be associated with health-related condition(s) considered important to
prevent.
S
sample A select subset of a population. A sample may be random or non-random
and may be representative or non-representative. There are several types of
samples.
See “representative sample”; “random sample”.
sampling The procedure of selecting a number of subjects from all the subjects in a
particular group or “universe”.
scale A set of numbers or other symbols used to designate characteristics of a
variable that is used in measurement. A system for measuring equal portions.
scatter diagram A graph in which each dot represents paired values for two
continuous variables, with the X axis representing one variable and the Y axis
representing the other; used to display the relationship between two variables;
also called a scattergram.
search engine An online service that compares search criteria with its database of
information on the Internet and displays the results.
secondary data analysis This type of analysis utilizes existing data sources either
through synthesis or integration; meta-analysis is an example of secondary data
analysis.
secular trend Changes over a long period of time, generally years or decades.
Examples include the decline of tuberculosis mortality and the rise, followed by a
decline, in coronary hearth disease mortality in Western countries.
selection See “sampling”.
selection bias Error due to systematic differences in characteristics between those
who take part in a study and those who do not. Selection bias invalidates
conclusions and generalizations that might otherwise be drawn from such studies.
self-rated health status / perceived health status Health status is usually
obtained from survey data by asking the respondent if his/her health is excellent,
very good, good, fair or poor (or similar questions).
sensitivity A high rate of detection of “true positives”, for example, the fraction of
subjects who actually received good care who are classified as recipients of good
care. For medical screening tests, sensitivity is the proportion of truly diseased
persons in the screened population who are identified as diseased by the
screening test. Sensitivity is a measure of the probability of correctly diagnosing
a case, or the probability that any given case will be identified by the test
(synonymous with ‘true positive rate’).
sex ratio The ratio of one sex to another. Usually defined as the ratio of males to
females.
86

single-blind trial See “blinding”.
skewed A distribution that is asymmetrical.
specificity A high rate of detection of “true negatives”, for example, the fraction of
subjects who actually received bad care who are classified as recipients of bad
care. For medical screening tests, the proportion of truly non-diseased persons
who are so identified by the screening test. It is a measure of the probability of
correctly identifying a non-diseased person with a screening test (synonymous
with ‘true negative rate’).
standard deviation A measure of the amount by which each value deviates from
the mean; equal to the square root of the variance, i.e. the square root of the
average of the squared deviations from the mean. It is the most commonly used
measure of dispersion of statistical data.
standard error In statistics, the standard error is defined as the standard deviation
of an estimate. That is, multiple measurements of a given value will generally
group around the mean (or average) value in a normal distribution. The shape of
this distribution is known as the standard error.
standard population A population in which the age and sex composition is known
precisely, as a result of a census. A standard population is used as a comparison
group in the procedure for standardizing mortality rates.
standardization A set of techniques used to remove, as far as possible, the effects
of differences in age or other confounding variables when comparing two or more
populations. The common method uses weighted averaging of rates specific for
age, sex, or some other potential confounding variable(s) according to some
specified distribution of those variables. The two main methods are direct and
indirect standardization.
statistical significance See “probability”.
statistical test A mathematical formula (or function) that is used to determine if the
difference between outcomes of a treatment or intervention and a control group is
great enough to conclude that the difference is statistically significant. Statistical
tests generate a value that is associated with a particular P value. Among the
variety of common statistical tests are: F, t, Z, and chi-square. The choice of a
test depends upon the conditions of the study, e.g. what type of outcome variable
is used, whether or not the subjects are randomly selected from a larger
population, and whether it can be assumed that the outcome values of the
population have a normal distribution or other type of distribution.
statistics The science and art of collecting, summarizing and analysing data that
are subject to random variation. The term is also applied to data themselves and
to summarizations of data.
stratification The process or result of separating a sample into sub-samples
according to specified criteria, such as age or occupational group.
surrogate measure The substitution of one measure for one that cannot be
measured in the course of a study.
87

survey / survey instrument An investigation in which information is systematically
collected but in which the experimental method is not used. A population survey
may be conducted by face-to-face inquiry, by self-completed questionnaires, by
telephone, by postal service, or in some other way. Each method has its
advantages and disadvantages. The ability to generalize from the results
depends upon the extent to which those surveyed are representative of the entire
population.
synthetic study A study that does not generate primary data but that involves the
qualitative or quantitative consolidation of findings from multiple primary studies.
Examples are literature review, meta-analysis, decision analysis and consensus
development.
systematic review A review of studies in which evidence has been systematically
searched for, studied, assessed and summarized according to predetermined
criteria.
systems error An error that is not the result of an individual's actions, but the
predictable outcome of a series of actions and factors that comprise a diagnostic
or treatment process.
T
targeting / target population / target group The collection of individuals, items,
measurements, etc., about which one wants to make inferences. The term is
sometimes used to indicate the population from which a sample is drawn and
sometimes to denote any “reference” population about which inferences are
required.
temporal trend See “secular trend”.
theory In science, an explanation for some phenomenon which is based on
observation, experimentation and reasoning. In popular use, a theory is often
assumed to imply mere speculation, but in science, something is not called a
theory until it has been confirmed over the course of many independent
experiments. Theories are more certain than hypotheses, but less certain than
laws.
treatment effect The effect of a treatment (intervention) on outcomes, i.e.
attributable only to the effect of the intervention. Investigators seek to estimate
the true treatment effect using the difference between the observed outcomes of
a treatment group and a control group.
trend A long-term movement in an ordered series, such as a time series. An
essential feature is that movement, while possibly irregular in the short term,
shows movement consistently in the same direction over a longer term. The term
is also used loosely to refer to an association which is consistent in several
samples or strata, but is not statistically significant.
triple-blind trial See “blinding”.
Type I error Also known as “false positive” or “alpha (α) error”. An incorrect
judgment or conclusion that occurs when an association is found between
variables where, in fact, no association exists. In an experiment, for example, if
the experimental procedure does not really have any effect, chance or random
error may cause the researcher to conclude that the experimental procedure did
have an effect. The error of rejecting a true null hypothesis.
88

Type II error Also known as “false negative” or “beta (β) error”. An incorrect
judgement or conclusion that occurs when no association is found between
variables where an association does, in fact, exist. In a medical screening, for
example, a negative test result may occur by chance in a subject who possesses
the attribute for which the test is conducted. The error of failing to reject a false
null hypothesis.
U
unit (of analysis) The unit to which a performance measure is applied (e.g.
subjects, patients, clinicians, group of professionals).
univariate Studying the distribution of cases of one variable only.
V
validity The extent to which a measurement, test or study measures what it
purports to measure. There are various types of validity:
construct validity: The degree to which an instrument measures the
characteristic being investigated; the extent to which the conceptual definition
matches the operational definition.
content validity: Verification that the method of measurement actually measures
what it is expected to measure, covering all areas under investigation reasonably
and thoroughly.
criterion validity: Verification that the instrument correlates with external criteria
of the phenomenon under study, either concurrently or predictively.
external validity: The extent to which study results can be generalized beyond
the sample used in the study.
face validity: A type of content validity, determining the suitability of a given
instrument as a source of data on the subject under investigation, using
commonsense criteria.
internal validity: the extent to which the effects detected in a study are truly
caused by the treatment or exposure in the study sample, rather than being due
to other biasing effects of extraneous variables.
variable Any quantity that varies. Any attribute, phenomenon or event that can
have different values.
variance A measure of the variation shown by a set of observations, defined by the
sum of the squares of deviations from the mean, divided by the number of
degrees of freedom in the set of observations.
vital statistics Systematically tabulated information concerning births, marriages,
divorces, separations and deaths, based on registrations of those vital events.
W
weighted data Any information given different weights in calculation or data in
which values for some cases have been adjusted to reflect differences in the
number of population units that each case represents.
89

Z
Z score Score expressed as a deviation from the mean value, in standard deviation
units.
