The relationship between Quality and Outcomes Framework scores and socioeconomic deprivation: a longitudinal study.

Abstract

The Quality Outcomes Framework (QOF) is a pay incentive scheme in England designed to improve and standardise general practice. QOF attainment has been used as a proxy for primary care quality in previous research. To investigate whether there is a relationship between socioeconomic deprivation and QOF attainment in primary care in England. Retrospective longitudinal study of primary care providers in England. QOF scores were obtained for individual general practices in England from between 2007-2019 and linked to practice-level Indices of Multiple Deprivation (IMD) scores derived from census data. Beta regression analyses were used to analyse the relationship with either percentage of total QOF attainment or of domain-specific attainment with multivariate analyses, adjusting for additional practice-level demographics. QOF attainment in the most affluent quintile was used as the reference group. General practices in less deprived areas have consistently outperformed those in more deprived areas in terms of QOF achievement. Initially, the gap between least and most deprived practices decreased, however since 2015 there has been relatively little change in comparative performance. The magnitude of inequality was reduced after adjusting for demographic factors. Of the independent variables analysed, the proportion of patients aged >65 years ('over 65s') had the strongest relationship with QOF attainment. There remains an inequality in primary care quality by socioeconomic deprivation in England, even after accounting for demographic differences.
