Ratio of obsevred vs. expected prevalenceThere is an under-reporting of prevalence, especially for hypertension (Table 1).Looking at practice level data, there is an association between deprivation andpractice performance in the recording of prevalence for some of the vasculardiseases. Practices in more deprived areas tended to have higher levels ofunrecorded prevalence for CHD and stroke (Figure 5 & 6) resulting in poorer accessto treatment. An opposite association was seen for diabetes (Figure 7) with practicesin the least deprived areas more likely to have higher levels of unrecordedprevalence.Figure 5:Prevalence Recording Ratios for CHD (r=0.537,r 2 = 28%)38491.131.030.930.83218316412 3142 3330 10 3275243475126462145535410.730.630.531352064414131937172482894825273936232240341115500.430 10 20 30 40 50 60 70Percentage of GP population in most deprived IMD quintile29CHD Ratio Mid Range IMD1 CHD Dudley Average Ratio CHD England Average RatioSource: Quality Outcomes Framework disease register 2008/09Primary Care Mortality Data GP Registered PopulationDepartment of Communities & Local Government Indices of Deprivation 200765
