Patient choice is a concept introduced into the NHS in England. Most patients are supposed to be able to choose the clinician whom they want to provide them with healthcare and that money to pay for the service should follow their choice. Before the advent of the internal market, in principle, a GP could refer a patient to any specialist in the UK. When contracts were introduced in 1990 these were called extracontractual referrals. From 1999 the concept of Out of Area Treatments was developed. These referrals were not necessarily related to choice made by a patient. Specialised treatments were not, and are not, available in every area.
