Explain the concept of a Just Culture
Review definitions related to medication safety

4. Occupational injuries cause 6,000 deaths per year
7,000 deaths yearly are caused by medication errors1

5. Human Factors – Confront Two Myths
If people try hard
enough they will not
commit medication
errors.
If we punish people
when they make an error
they will make fewer of
them.
The perfection myth: The punishment myth:
6. Human Factors – Error Types
Rule & knowledge based
errors arise when a
situation is
misinterpreted or a rule
is misapplied
Errors resulting from
intended deviation from
accepted standards,
procedure and rules
Unintended Actions
(Right idea, wrongly
actioned)
Intended
Actions
Lapses
Slips
Errors in performance of
a skill based behaviour,
typically occur when
attention is diverted
Mistakes
(wrong idea)
Violation
(rule breaking)
Unsafe
actions

Product of Our Current
System Design and
Behavioral Choices
Manage through
changes in:
• Choices
• Processes
• Procedures
• Training
• Design
• Environment
A Choice: Risk Believed
Insignificant or Justified
Manage through:
• Removing incentives
for at-risk behaviors
• Creating incentives
for healthy behaviors
• Increasing situational
awareness
Conscious Disregard of
Substantial and
Unjustifiable Risk
Manage through:
• Remedial action
• Punitive action
The Three Behaviors
8. 1436-05 Just / Accountabillity Culture
Just Culture / Culture Of Accountability
Punitive Culture
• Before the 1990s
• Frontline workers were
afraid to report their
own errors or those of
a colleague
• Missed enormous
opportunities to learn
about Errors
• Little insight into
System-based causes
Blame-Free Culture
•By the mid 1990s
•Supported a "no-
blame" response to
errors
•Unsafe acts were the
result of mental slips or
lapses, or honest
mistakes
•Fails to tackle
individuals who make
unsafe / reckless
behavioral choices
Just Culture
• NEW
• Recognize that humans
are imperfect so errors
will and can happen to
anyone
• Staff are encouraged
(even rewarded) for
reporting errors
• There is a well-
established system of
accountability
• High insight into
System-based causes

Adverse Drug
Reaction (ADR)
10. Definitions
Adverse Drug Event (ADE)
An injury from a drug-related intervention, and can include
Adverse Drug Reaction and can result from errors in prescribing,
dispensing and administration.
Adverse Drug Reaction (ADR)
A response to a medicinal product which is noxious and
unintended and which occurs at doses normally used for the
prophylaxis, diagnosis or therapy of disease or for restoration,
correction or modification of physiological function.
(APP 1434-07 Adverse Drug Events)
11. Definitions
Medication Error
Medication Error refers to any preventable event that may cause
or lead to inappropriate medication use or patient harm while the
medication is in the control of the health care professional, patient
or consumer.
Such events may be related to professional practice, health care
products, procedures, and systems, including prescribing; order
communication; product labeling, packaging, and nomenclature;
compounding; dispensing; distribution; administration; education;
monitoring; and use (ISMP, ASHSP, NCC MERP). Significant
medication errors are all medication errors.
(APP 1434-07 Adverse Drug Events)
12. Definitions
Near Miss (Close Call)
An event, situation, or error that took place but was captured BEFORE
reaching the patient.
Example: The wrong drug was dispensed by pharmacy, and a nurse
caught the error before it was administered to the patient.
Hazardous situations
refers to circumstances or events that have the capacity to cause error
(e.g., confusion over LASA drugs or similar packaging).
Defective Medicine
It is a medicine where the product presentation and quality is not in
accordance with regulation and professional standards.
(National Patient Safety Agency, UK)
(APP 1434-07 Adverse Drug Events)
13. Definitions
Latent Failure (hidden / dormant errors)
Refer to less apparent failures of organization or design
that contributed to the occurrence of errors or allowed
them to cause harm to patients. (Agency for Healthcare Research and Quality)
Environmental Factors (e.g. Noise, poor light, etc.)
Technology Factors
Lack of and / or complex policies and procedures
Communication Factors

Errors NOT Intercepted (ADE)

84%
High incidence for ADEs due to medication administration errors justify the need to
target interventions to prevent these errors in a hospital setting.

17. Verbal and Telephone Orders
Why Standardize Verbal / Telephone Orders?
Inherently problematic: Different accents and limited short-term
memory.
When do you take a telephone order?
Emergent situation
Urgent situation: The prescribing practitioner has determined
that the patient is in need of a medication within a specific time
period and he / she is unable to physically enter the order in the
patient's clinical record due to his / her physical location.
APP 1429-03 Prescribing and Dispensing Medication Guidelines
18. Verbal and Telephone Orders
Telephone Order Procedure
1st Nurse records, 2nd Nurse “Reads Back”
“Read Back” – NOT repeat back
Spell out 1- 5 for 15 [confused with 50]
NOT allowed for the following:
Chemotherapeutic agents
Parenteral nutrition
Initiation of:
Epidural medications
Patient Controlled Analgesia / narcotic drips
Parenteral pressor agents
Parenteral skeletal muscle relaxants
19. System Focused Thinking
Humans are imperfect
Accept that errors will occur
Focus on the system, not
the people
