List of District Health Authorities in England and Wales
District Health Authorities were administrative units of the National Health Service in England and Wales from 1982 to 1996.
The districts were a second tier below the health regions. They replaced the Area Health Authorities (which generally corresponded to non-metropolitan counties, metropolitan boroughs or groups of London Boroughs) and the District Management Teams that ran the hospitals on a day to day basis. These two layers of administration had been introduced in 1974.
The Districts were reorganised on a number of occasions in the 1990s, and were abolished in 1996, when new single-tier Health Authorities replaced both Districts and Regions.
