Having estimated the number of CHD events likely to occur in the different target
groups, attention is now turned to the measurement of the effectiveness of the four
interventions. The effectiveness evidence on each intervention stems from the relevant
papers, discussed in section 3.2. This paper has used the effectiveness measures (that is,
reduction in risk factors) of these studies and translated them into the epidemiological
profile of the South Western Sydney region.
For the ‘high-risk individual’ intervention, the population estimates do not take into
account the overlap which may exist between risk factors. That is, a large group of
people may have multiple risk factors. Hence, the figures in Table 5 can not be
aggregated to obtain the total number of CHD deaths. This rule applies to the “high-
risk individuals” and the “high-risk groups” interventions.
To overcome this problem, it has been assumed that for “high-risk individuals” there is
an overlap of people with multiple risk factors of approximately 30 %. In the “high-risk
group” intervention, we have assumed there is 100 % overlap between people living in
low SES areas, ethnicity and Aboriginal and Torres Strait Islander people.
