|Administrative history||On 1 April 1994 a merger between The Royal London Hospital and Associated Community Services NHS Trust, St Bartholomew's Hospital and The London Chest Hospital resulted in the creation of a Trust formally known as The Royal Hospital of St Bartholomew, The Royal London Hospital and The London Chest Hospital NHS Trust. For everyday usage, the Trust was known as The Royal Hospitals NHS Trust. The Chairman of the new Trust was Sir Derek Boorman KCB, and the Chief Executive was Mr Gerry Green.|
Management of the Queen Elizabeth Hospital for Children came under the Trust in 1995 and the hospital was formally part of the Trust from April 1996 until the hospital's closure in 1998, whereupon children's services transferred to The Royal London Hospital.
In 1999 the Trust's name changed to Barts and The London NHS Trust. The Trust continued until a further merger with Whipps Cross University Hospital NHS Trust and Newham University Hospital NHS Trust in 2012. The new Trust created as a result of this merger was called Barts Health NHS Trust.
The Royal Hospitals/Barts and The London NHS Trust initially came under the North East Thames Regional Health Authority, and East London and The City District Health Authority more locally. From 1996-2002 it fell under NHS London Regional Health Authority and then North East London Strategic Health Authority until this was subsumed into NHS London Strategic Health Authority in 2006.
