Does general practice reduce health inequalities? Analysis of quality and outcomes framework data

The government set a series of targets to reduce health inequalities in England by 2010. Primary care has an important role in reducing health inequalities. The aim of the study was to assess the impact of general practice on reducing area-based health inequalities.

Analysis of differences in achievement on clinical indicators between practices in Spearhead and non-Spearhead Primary Care Trusts (PCTs) using data from the Quality and Outcomes Framework (QOF) for 2004/05 and 2005/06, practice characteristics and Spearhead status of PCTs. The study used data on 8339 primary care practices in England. Unweighted mean reported achievement on subset of 26 clinical indicators was calculated. The study analysed differences in achievement by Spearhead status and deprivation in both years and the change between years. Multiple regression analysis of relationship between Spearhead status, income deprivation, reported achievement and other factors also were carried out.

Practices in Spearhead PCTs performed worse than practices in non-Spearhead PCTs in both years but showed greater improvement. Among the most deprived practices, there were no differences in QOF achievement between Spearhead and non-Spearhead PCTs. Previous year's achievement was the strongest predictor of performance.

The narrowing in performance between practices in Spearhead and non-Spearhead PCTs may have indirectly contributed to a reduction in area-based health inequalities but the differences are small. The lack of difference between the most deprived practices in Spearhead and non-Spearhead PCTs suggest that area-based initiatives to tackle inequalities have not yet had an observable impact on deprived practices. Unobserved factors explain most of the variation in achievement.
