The Quality and Outcomes Framework (QOF) is a financial incentive scheme for general practitioners in the UK. It was introduced in 2004 with the aim of improving the quality of primary care and reducing health inequalities in primary care delivery. There is relatively little evidence to support the hypothesis that practices with higher quality of care measured by the QOF score have better health outcomes. However some studies have shown that higher QOF scores are associated with lower admission (Bottle et al. 2008b; Kiran et al. 2010). In both studies the association was stronger in practices with higher deprivation/lower socioeconomic distribution. The aim of this study is to assess whether high quality primary care, measured using quality of care measures, is associated with lower coronary heart disease morbidity and mortality in an area of relatively low deprivation. This is an ecological study using data from four years before and four years after the introduction of QOF. The study will compare these time periods for any change in CHD admissions and mortality. The study will also assess whether there is an association between quality of care measures on specific coronary heart disease and associated hospital admission rates and mortality rates. The study will also assess whether any association is affected by the practice based deprivation score. Results of this study will be presented at the conference.
