The purpose of this research is to inform a review of the General Medical Services (GMS) contract formula in England. The current contract includes a formula (the “Carr-Hill” formula) designed to reflect workload at practice level. This formula is now recognised to be out of date as the nature of General Practice (GP) workload has changed since this was developed. The proposed research will produce a new model measured either by total ‘case opening’ time or ‘number of file openings’ and will include age, sex, new registrations and deprivation, alongside practice characteristics such as QOF disease prevalence as explanatory variables in the new workload formula. Generalised linear models will be developed to model the relationship between case opening times and model parameters in a training dataset. The final model will be evaluated in a test and independent dataset. The GP workload formula will be combined with a formula for cost (developed in a separate non-CPRD study) to inform both CCG level primary care resource allocation and resource allocation for each GMS practice.
The expectation is that the new formula will better allocate resources to CCGs and practices to better meet need across primary care, benefitting patients across the whole system.
