Multicenter Study
Determinants of primary medical care quality measured under the new UK contract: cross sectional study.
To identify factors associated with the quality of primary medical care incentivised under the new UK general medical services contract. ⋯ Population characteristics showed little association with the quality of primary medical care incentivised under the UK general medical services contract. Larger clinical teams delivered higher quality clinical care, but the nurse-doctor composition of the clinical team did not influence quality. Practices that were more likely to respond to financial incentives because of previous behaviour or lower income from other sources recorded higher quality. If generalisable, the results suggest that initiatives to improve primary medical care quality should focus on the structure and resourcing of providers.
