1. The Finding the five Thousand project
Health inequality audits in Barnet of deaths from coronary heart disease (CHD) (and thus, by
implication, also from stroke) show a persisting higher death rate in those aged under 75 years
who live in the more deprived parts of the borough. We have also identified that the post code
of Barnet GP-registered patients admitted to hospital with heart attacks has no relationship to
the treatment they receive. Our hypothesis is thus that higher CHD death rates amongst those
living in more deprived areas reflect higher levels of unrecognised and/or unmanaged CHD and
stroke risk factors.
We have identified the full post codes of some 13,500 households living in social housing, i.e.
in some of the borough’s most deprived areas.
About 85% of Barnet residents living in social housing are registered with Barnet GPs. The
majority are registered in 21 out of a total of 72 practices, which are located in or adjacent to
some of the most deprived parts of the borough, as shown in Figure 1.
Quality and Outcomes Framework (QoF) data in these practices show that most are achieving
above-maximum threshold performance in terms of controlling blood pressure in people known
to have high blood pressure, a past history of CHD or stroke, diabetes and/or chronic kidney
disease. Put another way, QoF data suggest that these practices are providing good quality
care for all those patients with an established disease that increases the risk of heart attack or
stroke.

2. With help from Pfizer Ltd, we have obtained Health Acorn data and used this to model various
characteristics of the populations in these areas. Modelling with these data suggests that there
are many more people in these practices who are smokers and/or who are obese than is
currently recognised. Put another way, in these practices there is likely to be a large number of
people with unidentified and thus currently unmodified risk factors for CHD and stroke, such as
smoking, hyperlipidaemia, pre-diabetes, diabetes and hypertension. This is shown in Figure 2.
The ethnic makeup of the people registered in these practices also differs from the Barnet
average. This is shown in Table 1. This is relevant because (i) people in different ethnic groups
can have different likelihoods of developing certain conditions, such as diabetes and high blood
pressure, and (ii) people in different ethnic groups have different beliefs and cultural values and
behaviours that require different approaches if we are to engage them effectively in reducing
vascular disease risk factors.
It is important to note that the expected prevalences of risk factors are modelled; they do not
represent actual data for individual people. However, they tend to corroborate our hypothesis
that higher CHD death rates amongst people living in the more deprived parts of the borough
are probably due to unrecognised and/or unmanaged CHD and stroke risk factors.

obesity and who smoke
We also think it likely that the majority of these people do not visit their GP surgery. We
therefore need to find ways to engage them individually in the community, identify those at risk
(e.g. by measuring their blood pressure and body mass index and identifying smokers) and
encourage and enable them to attend their GP surgery for management.
We further think it likely that many of these people will not yet have identifiable disease, such
as diabetes or a history of heart attack or stroke. Targeted work by their GP practices to

aspects of the GP contract and thus require a local enhanced service payment. I recommend
that any such payment should be based on the achievement of pre-defined blood pressure,
lipid and glycosylated haemoglobin levels as well as the identification of those with abnormal
metrics such as raised blood cholesterol. Smoking cessation is covered by existing
arrangements.

Barnet has been selected as a pilot site by the London Social Marketing Group (engaged by
NHS London). In collaboration with Pfizer Ltd and Barnet Council, we are currently undertaking
a social marketing research exercise with two companies, TNS and thinkpublic.
The TNS work is concentrating on issues such as:

4.  do people recognise heath risks? What is important? What is not? What matters to them in
health terms?
 what might influence them to see health as an important issue (especially in terms of heart
disease and stroke and in relation to smoking and problems like raised blood cholesterol,
diabetes and high blood pressure)?
 what might influence them to have aspects of their health checked? and
 where might they go for such checks?
The thinkpublic work is looking to:
 explore the lives of people at risk from vascular problems in relation to accessing support
services;
 identify the reasons why these people do not access the vascular check service;
 aim to identify how people internalise Barnet’s existing messages and the drivers behind the
target audiences’ behaviours;
 explore different approaches to communicating with the target audience; and
 produce a clear set of recommendations for Barnet’s social marketing campaign.
Using Health Acorn data, and to enable better targeted research of the main population
segments, we have identified streets in Barnet in these social housing areas where there are
much higher proportions of White, Asian or Black people.
The outcomes of this market research will be used to inform pilot work with the London Social
Marketing Group and the PCT working collaboratively with Barnet Council. This will probably
include activities such as:
 leaflet drops in specific streets targeted at the population segments most likely to be living
there;
 letters to individuals, probably through or on behalf of their GP surgery, inviting them for a
health check;
 posters at bus stops, on the back of public toilet doors (e.g. in pubs and shopping centres)
and elsewhere, targeted at the population segments most likely to be living/working/going
there, publicising the issue;
 publicity in public places, e.g. supermarkets, shopping malls, targeted at the population
segments most likely to be going there, publicising the issue;
 posters in GP surgeries and community pharmacies, targeted at the population segments
most likely to be attending there, publicising the issue;
 publicity in work places, e.g. Barnet PCT, Barnet Council, public transport depots, targeted at
the population segments most likely to be working there, publicising the issue; and
 advertorial in local papers and, as may be possible, items on local radio, publicising the
issue.
