In addition to the incentives of the Quality and Outcomes Framework, an integral part of the General Medical Services contract which remunerates GPs, there are a number of Directed Enhanced Services offering increased care for patients in which GP practices can participate and earn income over and above their global sum allocation from the boards. The extra remuneration given by NHS boards to GP practices to dispense to their patients is intended solely to cover the costs of delivering that service, and is not provided to cross-subsidise other services.
