Abstract

OBJECTIVETo examine ethnic disparities in diabetes management among patients with and without comorbid medical conditions after a period of sustained investment in quality improvement in the U.K.RESEARCH DESIGN AND METHODSThis cross-sectional study examined associations between ethnicity, comorbidity, and intermediate outcomes for mean A1C, total cholesterol, and blood pressure levels in 6,690 diabetes patients in South West London.RESULTSThe presence of ≥2 cardiovascular comorbidities was associated with similar blood pressure control among white and South Asian patients when compared with whites without comorbidity but with worse blood pressure control among black patients, with a mean difference in systolic blood pressure of +1.5, +1.4, and +6.2 mmHg, respectively.CONCLUSIONSDespite major reforms to improve quality, disparities in blood pressure management have persisted in the U.K., particularly among patients with cardiovascular comorbidities. Policy makers should consider the potential impacts of quality initiatives on high-risk groups.
