10.1.3.6 Diagnosed Prevalence in Relation to Deprivation
It is possible to assign a deprivation score to each general practice using the Index of
Multiple Deprivation 2007 score assigned to each patient (based on their postcode) and
calculate the mean IMD 2007 score for each practice (i.e. weighted by patient
population). Table 212 shows the prevalence of diagnosed stroke and TIA on the
practice disease registers for 2009/10 grouping the practices into five groups. Figure
193 shows the practice IMD 2007 scores and the prevalence of diagnosed stroke and
TIA for each practice. The linear regression line is also shown and indicates that there
is no association between the deprivation score and the prevalence of diagnosed stroke
and TIA (p=0.63). One would expect an association to exist, so this could suggest that
patients are more likely in the most deprived areas to have stroke and TIA which is
undiagnosed. However, overall mortality rates in the more deprived areas are higher,
including mortality rates from stroke, so people in the more deprived areas may be less
likely to be „living with a previous stroke‟ and also to have lived with a stroke a shorter
length of time (as a higher proportion of them die sooner than in more deprived areas).
The underlying data for the figure is given in the APPENDIX on page 908.
This information is for 2009/10 and comes from the Quality Management and Analysis
System (QMAS) from which an extract is taken at the end of March and should be
equivalent to the extract taken nationally which forms the QOF.
The latest list size refers to the registered population as at 1 st January 2010, but the
number and prevalence on the disease register is as at 31 st March 2010 (the same
definitions used in QOF), and this means that the prevalence can be biased if large
population changes have occurred over this three month period. This is the case for
practices Y02747, Y02786, Y02896 and Y02748 which all opened between 5 th October
2009 and 11 th January 2010, so these four practices have not been included.
