National Health Service

The National Health Service (NHS) is the umbrella term for the publicly funded healthcare systems of the United Kingdom, comprising the NHS in England, NHS Scotland and NHS Wales. Health and Social Care in Northern Ireland was created separately and is often locally referred to as "the NHS". The original three systems were established in 1948 as part of major social reforms following the Second World War. The founding principles were that services should be comprehensive, universal and free at the point of delivery—a health service based on clinical need, not ability to pay. Each service provides a comprehensive range of health services, provided without charge for residents of the United Kingdom apart from dental treatment and optical care. In England, NHS patients have to pay prescription charges; some, such as those aged over 60, or those on certain state benefits, are exempt.
