The last few years have been a time of considerable change for general practitioners in England. In 2004, general practitioners negotiated a new contract with the United Kingdom's National Health Service. In came a new pay for performance scheme, along with the option of opting out of after-hours primary care. General practitioners' pay increased and job satisfaction improved. However, rather than then entering a period of stability, general practitioners subsequently found themselves facing even more changes in their working practices. Workload has increased, new responsibilities for commissioning health services have been given to general practitioners, and their income has fallen.
