High Quality Content by WIKIPEDIA articles! The National Health Service or NHS is the publicly-funded healthcare system in England (though the term is also used to refer to three of the four national health services in the UK, collectively). The NHS provides healthcare to anyone normally resident in the United Kingdom with most services free at the point of use for the patient though there are charges associated with eye tests, dental care, prescriptions, and many aspects of personal care. The NHS has agreed a formal constitution which sets out the legal rights and responsibilities of the NHS, its staff, and users of the service and makes additional non-binding pledges regarding many key aspects of its operations.
