Introducing the Atlas of Variation in Healthcare for People
with Liver Disease

- 38 indicators mapped
- Covering topics ranging from
Transplantation, alcohol, prescribing,
and obesity, amongst other
- Produced with NHS Liver and the
Health Protection Agency
- contributions from 24 other
organisations

Preface

[This Atlas] will highlight gaps in prevention
initiatives and the provision of health services
and will draw attention to localities where
improvements are needed. Most importantly, it
will empower patients to ask questions about
the healthcare they receive and the options
available to them.

A key issue for population health

In the Annual Report of
the Chief Medical Officer
(CMO), Volume 1, 2011,
liver disease was
identified as one of three
key issues for population
health because it is:

“the only major cause of
mortality and morbidity
which is on the increase
in England...”

4

…whilst it is decreasing in our European partners

5

Mortality from liver disease has been increasing for the past 20 years.
During the last few years, it appears to have reached a plateau,
although it is not known whether this trend in mortality can be
reversed

6

The key facts

• 1993-2010: 88% rise in England in age-standardised mortality
rate from chronic liver disease
• Up to 10-20% of the population are potentially at some risk
of developing some liver damage, while 600,000-700,000
individuals actually have a significant degree of damage.
• Over 24% of the population (33% of men, 16% of women)
consume alcohol in a way that is potentially or actually
harmful
• In England, there are potentially 1.4m adults with fatty liver
disease. 26% of the adult population in England is thought to
be obese
• Up to 500,000 children may already be at risk of liver disease
because of their weight
7

Key Themes

• There is significant local variation in these mortality
rates, with deprivation a key factor. (Maps 1-5)
• Major evidence of alcohol abuse by children, with big
local variations in the numbers admitted to hospital for
alcohol-related problems. (Map 10)
• Unexplained variations in local prescribing patterns for
people with harmful drinking (Maps 12 & 14)
• Not all babies at risk of hepatitis B are being immunised
to protect them. (Map 17)
• Growing obesity in children is increasing the risk of
serious liver disease in later life. (Maps 28-29)

8

Why Variation matters…

Maps of variation in healthcare matter because they
support an understanding that different resources or
solutions may be required in different localities, but
they also serve as a powerful tool for orientation, a
comparator and a benchmark to show commissioners,
clinicians and providers where they stand among their
peers.

Maps can help to highlight localities where variation in
outcomes may require more detailed investigation or
a different solution.

9

Much more needs to be done at an earlier stage of liver disease to
reduce premature mortality. Indeed, the opportunities for
intervention and the effect of intervention probably diminish with
the progression of liver disease, whereas the relative costs of the
interventions that can be applied increase

10

Selected Maps of Variation

11

Emergency Admissions

In some localities, people are twice as
likely to be admitted to hospital as an
emergency attributable to liver disease.
Reasons could include differences in:

›› the distribution of risk factors for
liver disease;
›› the prevalence of liver disease in
different populations;
›› the types and volumes of liver
disease;
›› the coding of cases.

The degree of variation observed,
however, probably includes
unwarranted variation due to
differences in the organisation and
management of care for people with
liver disease in local health services.
12

Chronic Liver Disease

Premature death from chronic
liver disease has been rising -
between 1993 and 2010 the
directly age-standardised
mortality rate in England
increased by 88%.

There is a 9-fold variation in rates
for PCTs. When the five PCTs with
the highest rates and the five
PCTs with the lowest rates are
excluded, the variation is 3.9-fold.

13

Sources of Variation

Potential reasons for the degree of variation observed
include differences in:

›› the prevalence of diabetes, obesity, hepatitis B and
hepatitis C;
›› the level of alcohol consumption;
›› the level of investment in preventative measures;
›› the configuration of services;
›› the timing of diagnosis;
›› degree of adherence to clinical guidance;
›› level of patient compliance with prevention or treatment.

14

Chronic Liver Disease

Cirrhosis of the liver is an important
cause of illness and death.

In 2010, it killed more people than
were killed in transport accidents and
more women than cancer of the
cervix.

The rate of people admitted to
hospital at least once for cirrhosis
varied 3.9-fold.When the five PCTs
with the highest rates and the five
PCTs with the lowest rates are
excluded, the range is 60.7–171.6 per
100,000 population, and the variation
is 2.8-fold.

15

Liver Cancer

Around 3,900 people every year are
diagnosed with primary liver cancer
each year in the UK, which accounts
for about 1% of all cancers in the UK.

Secondary liver cancer, spreading
from elsewhere in the body, is far
more common than primary liver
cancer.

For PCTs in England, the rate of liver
cancer mortality in people aged under
75 years ranged from 0.5 to 5.3 per
100,000 population (10-fold
variation). When the 5 PCTs with the
highest rates and the 5 PCTs with the
lowest rates are excluded, the range is
0.8–3.6 per 100,000 population, and
the variation is 4.6-fold.
16

Transplantation

For PCTs in England, the rate of liver
transplants from all donors ranged
from 4.5 to 28.5 per million population
(pmp) (6-fold variation)

When the five PCTs with the highest
rates and the five PCTs with the lowest
rates are excluded, the range is 6.0–
22.5 pmp, and the variation is 3.7-fold.

Potential reasons for variation include
differences in:

›› access to local expertise in liver
disease;
›› criteria for selection for
consideration for liver transplant;
›› care pathways for people who may
require a liver transplant.
17

Alcohol Dependency

In England, alcohol dependence affects 4% of people aged
between 16 and 64 years (6% of men and 2% of women); over
24% of the population (33% of men and 16% of women) consume
alcohol in a way that is potentially or actually harmful to their
health or well-being.

In England, of the 1 million people aged 16–64 years who are
alcohol dependent, only about 6% per year receive treatment:

›› there is often a long period between developing alcohol
dependence and seeking help;
›› there is limited availability of specialist alcohol treatment
services in some parts of the country;
›› alcohol misuse is under-identified by health and social care
professionals.
18

Admissions for Alcohol Use

Alcohol misuse costs the country around
£21 billion a year1. In 2011, the
Department of Health estimated the cost
to the NHS of alcohol-related harm as
£3.5 billion.

The rate of alcohol-related admissions
ranged from 1048.1 to 3557.3 per
100,000 population (3.4-fold variation).
When the 5 PCTs with the highest rates
and the 5 PCTs with the variation is
2.1-fold.

Some of the variation is likely to be due to
differences in alcohol use, although other
factors such as differences in coding for
association with alcohol could explain
some of the variation.

32/132we02.htm
19

Admissions for Alcohol use
For PCTs in England, the rate of
alcohol-specific conditions in people
aged under 18 years ranged from 16.9
to 138.3 per 100,000 population (8-
fold variation). When the 5 PCTs with
the highest rates and the 5 PCTs with
the lowest rates are excluded, the
variation is 4.7-fold.

Much of the variation observed is likely
to be due to differences in the rate of
alcohol use. Other reasons for
variation include the level of
deprivation, which appears to have an
adverse impact, the level of obesity,
which can worsen the impact of
alcohol, demography, and coding for
association with alcohol

20

Hepatitis and Drug Use

People who inject drugs are at greatest risk of hepatitis C infection.
Infections are acquired when people share contaminated injecting
equipment.

Ensuring people who use drugs do not contract hepatitis is one way of
ensuring their safety and that of the local community before and during
their recovery. Preventing transmission also has benefits for civil
society by reducing:

›› harms to health;
›› treatment costs.

When people who inject drugs receive treatment for their addiction, it
provides an opportunity to undertake hepatitis C testing to identify
new cases.

21

Hepatitis

For PCTs in England, the percentage of
hepatitis C test uptake among people who
inject drugs receiving drug treatment
ranged from 14.8% to 87.4% (6-
fold variation).

percentages and the five PCTs with the
lowest percentages are excluded, the
range is 26.5–74.2%, and the variation is
2.8-fold.

When interpreting the magnitude of
variation, it is important to note:

›› the indicator does not include people
who do not start treatment at all and/or
who are not in touch with services;
›› some people who inject drugs are very
mobile and may present to different
services at different times.
22

Hepatitis
Although hepatitis C virus is a chronic
infection, antiviral treatments are available
that will successfully clear the virus in the
majority of patients. However, unless there
is a considerable increase in people
receiving effective treatment, the future
burden of hepatitis C-related disease will
be substantial.

Admission to hospital for hepatitis C and
end-stage liver disease (ESLD) is an
outcome indicator of how successful the
identification and care of people with
hepatitis C and its prevention have been.

There is an 11 fold variation in the rate of
hospital admissions for hepatitis C-related
ESLD when the five PCTs with the highest
rates and the five PCTs with the lowest
rates are excluded.

23

The Obesity Epidemic

In England, there are potentially 1.4 million adults with fatty liver
disease which may in some cases to lead to cirrhosis (non-alcoholic
steatohepatitis) over the long term. We also estimate that there could
be 60,000 10-year-olds with fatty liver. Extrapolating this for children
aged 5–15 years, up to 500,000 children may already be at risk of
developing an underlying liver disease that could lead to cirrhosis in the
future.
Obesity is closely related to
the development of fatty
liver disease, and 26% of the
adult population, around
14.3 million people in
England, is thought to be
obese

24

Obesity
For PCTs in England, the percentage
of children in school year 6 classified
as overweight or obese ranged from
24.6% to 41.8% (1.7-fold variation).

percentages and the five PCTs with
the lowest percentages are excluded,
the range is 28.8–40.3%, and the

25

Obesity
For PCTs in England, the
percentage of estimated adult
obesity ranged from 14.0% to
30.7% (2.2-fold variation).

When the five PCTs with the
highest estimated
percentages and the five PCTs
with the lowest estimated
percentages are excluded, the
range is 15.6–29.0%, and the

26

Cholecystectomy
The degree of variation observed in total
rates of cholecystectomy after exclusion is
2.4-fold whereas it is 8-fold for the
percentage of elective adult day-case
laparoscopic cholecystectomy per all
elective cholecystectomies. If total rates of
cholecystectomy are considered as a proxy
for the burden of disease, it would appear
that there is less variation in the burden of
disease when compared with the variation
in the type of care given.

Further investigation is needed into the
possible causes of lower rates of day-case
surgery.

If all providers in England were to match
the day case performance of those in the
upper quartile of day-case surgery rates for
the BADS set of procedures, the estimated
annual saving could release more than £64
million.
28

Endoscopic Retrograde
Cholangiopancreatography

ERCP is a procedure in which an
endoscope and X-rays are used to
visualise the bile duct and the
pancreatic duct. It can be used to
diagnose or treat various conditions
such as bile duct stones or pancreatic
cancer. There should be no reason
why the majority of patients
undergoing the intervention as an
elective procedure require an
overnight stay.

For PCTs in England, the variation is
28-fold. When the five PCTs with the
highest percentages and the five
PCTs with the lowest percentages are
excluded, the variation is 13-fold.

29

Endoscopic Retrograde
Cholangiopancreatography

The degree of variation observed in total rates of cholecystectomy after
exclusion is 2.4-fold (see Map 31) whereas it is 8-fold for the percentage of
elective adult
day-case laparoscopic cholecystectomy per all elective
cholecystectomies.

The degree of variation observed in total rates of ERCP procedures after
exclusion is 2.2-fold (see Map 33) whereas it is 13-fold for the percentage
of elective ERCP procedures performed as day cases.

If total rates of cholesystectomy and ERCP are considered as a proxy for
the burden of disease, it would appear that there is less variation
in the burden of disease when compared with the variation in
the type of care given. Further investigation is needed into the
possible causes of lower rates of day-case procedures.

30

Reasons for variation
The degree of variation observed in total rates of cholecystectomy
after exclusion is 2.4-fold (see Map 31) whereas it is 8-fold for the
percentage of elective adult day-case laparoscopic cholecystectomy
per all elective cholecystectomies.

The degree of variation observed in total rates of ERCP procedures
after exclusion is 2.2-fold (see Map 33) whereas it is 13-fold for the
percentage of elective ERCP procedures performed as day cases.

If total rates of cholecystectomy and ERCP are considered as a proxy
for the burden of disease, it would appear that there is less variation
in the burden of disease when compared with the variation in
the type of care given.

Further investigation is needed into the possible causes of lower
rates of day-case procedures.
31

Innovations and models of good practice in services
While working on the National Liver Disease Strategy, many models of good
practice and some innovations likely to be helpful in tackling unwarranted
variation were identified (Figure CS.1). They are presented in this Atlas as
exemplars so that commissioners, clinicians and service providers can
consider how they may be applied in their locality.

32

Identifying liver disease earlier

Risk assessment and early recognition of liver disease has been promoted
by Liverpool PCT-CCG through the use of a locally enhanced service payment
to minimise late diagnosis.

Incentives are available to all participating primary care groups who:

›› identify patients at risk;
›› undertake relevant blood tests;
›› refer only those patients who meet the criteria for referral that have been
agreed with local secondary care services – other patients are managed
entirely in the community

It was found that practices had different criteria and standards for referral within
the PCT. Referral criteria and information standards were agreed with
secondary care providers who agreed to provide a consultant-level opinion.

Up to 40% of patients can be discharged with an advisory care plan at first
consultation.
33

Nottingham

A variation of this type of service model was developed in
Nottingham where all CCG referrals from individual practices were
centralised at a single practice.

A two-level triage system was used, in which a general practitioner
with an interest in gastroenterology screened referrals. In cases
where there was uncertainty, a brief synopsis of the case was
emailed to 1 of 5 consultant hepatologists/gastroenterologists who
screened the scenario and made clinical recommendations.

Of a total of 354 potential referrals screened using this system during
one year, 75% of hepatology referrals were dealt with by giving
advice, blood tests, recommendations and appropriate community
management plans.

34

Alcohol abuse - Delivering brief interventions

The introduction of alcohol liaison nurses has been recommended by
the British Society of Gastroenterology and accepted by NHS
Evidence as a QIPP example.

In Nottingham, the introduction of an alcohol liaison nurse reduced
readmission rates and drinking rates during a 12-month follow-up
period.

Similar models have proved effective in Bolton and Liverpool.

In Salford, an extension of this process has been used to identify
frequent attendees at A&E who are also known to other local
authority agencies: a coordinated approach with key workers has
decreased attendances and readmission rates.

35

Triage of patients to secondary care…

In Southampton, an algorithm was developed to triage patients to no fibrosis
(green), cirrhosis (red), or an in-between group (amber) to whom
interventions could be targeted to impede progression of scarring disease in
the liver.
Three tests were used - hyaluronic acid, collagen P3 peptide, and platelet
count
Ten thousand people in primary care were contacted by their own GPs and
had their alcohol intake assessed:

›› just over 30% were assigned to the green category of
risk of liver disease;
›› just over 40% were assigned to the amber category
of risk of liver disease;
›› just under 30% were assigned to the red category of
risk of liver disease.

36

…Triage of patients to secondary care

After assessment at one year, it was found that the initial categorisation was
accurate with respect to not only the proportion of people assigned to each
category of risk but also the severity of liver disease attributed to each
individual.

By identifying people in each category, preliminary results suggest that the
higher the risk category identified, the greater is the impact of interventions
aimed at reducing alcohol consumption in each group. This and other
evidence points to the importance of individualising the information and risk
assessment for people at risk of liver disease.

37

Patient involvement: shared decision-making…

Involvement of patients in the decision-making process leads to higher
satisfaction, improved outcomes, greater knowledge of their condition and
increased adherence to treatments.

At University Hospitals Birmingham, patients were provided with the tools to
engage in the decision making process, including access to their own health
records, the ability to communicate with patients who have similar conditions
and access to appropriate healthcare resources.

A shadow hospital IT system was created that included the electronic
prescribing and electronic outpatient note-keeping systems, so that patients
could view their letters, appointments and blood-test results. As well as
being able to access their health records, patients can also communicate
with their healthcare team and learn about their long-term condition and its
management.

38

… Patient involvement: shared decision-making

After successful feedback about the pilot, the system went live in July 2012
to patients being treated within the entire liver medicine specialty and also 10
other specialities within the Trust.

After this initial rollout phase, there will be an external evaluation of the
project. This is the first such project for patients with liver disease, although
patients with kidney disease have experienced the benefits of a similar
system, known as Renal PatientView4, for many years1.
