General practice characteristics associated with pay-for-performance in the UK: a systematic review.

BACKGROUND

The Quality and Outcomes Framework (QOF), a pay-for-performance programme, has been the most widespread quality initiative in NHS general practice since 2004. It has contributed between 25% and 8% of practices' income during this time, but concerns about its effect on equity have been raised.

AIM: To understand which practice characteristics are associated with QOF performance.

DESIGN AND

SETTING

A systematic review was conducted, focusing on NHS general practice in the UK.

METHOD: MEDLINE, Embase, CINAHL+, Web of Science, and grey literature were searched for studies examining the association between general practice characteristics and QOF performance.

RESULTS

Twenty-two studies, published between 2006 and 2022, exploring the relationship between six population and 15 organisational characteristics and QOF measures were found. Most studies were cross-sectional, of English general practices, and used data from the early years of QOF. A negative association was frequently found between overall QOF performance and socioeconomic deprivation; increasing proportion of registered patients aged >65 years; increasing list size; increasing mean GP age; and Alternative Provider Medical Services contracts. Group practices (versus single-handed), more full-time equivalent (FTE) GPs, and being a training practice were frequently associated with better overall QOF performance. The associations of most other characteristics with performance were inconsistent.

CONCLUSION

Associations with characteristics both within and outside practices' control were identified. Pay-for-performance instruments may systematically disadvantage practices serving those at greatest risk of ill-health such as older and more deprived populations. Given the cross-sectional design of many studies and focus on the early years of QOF, more up-to-date evidence is needed to understand if and why these relationships persist.
