General medical services (GMS) is the range of healthcare that is provided by general practitioners (GPs or family doctors) as part of the National Health Service in the United Kingdom. The NHS specifies what GPs, as independent contractors, are expected to do and provides funding for this work through arrangements known as the General Medical Services Contract. Today, the GMS contract is a UK-wide arrangement with minor differences negotiated by each of the four UK health departments. In 2013 60% of practices had a GMS contract as their principle contract. The contract has sub-sections and not all are compulsory. The other forms of contract are the Personal Medical Services or Alternative Provider Medical Services contracts. They are designed to encourage practices to offer services over and above the standard contract. Alternative Provider Medical Services contracts, unlike the other contracts, can be awarded to anyone, not just GPs, don't specify standard essential services, and are time limited. A new contract is issued each year.
