The Caldicott Guardian

The purpose of the Caldicott Guardian originated from the 1997 report produced by the Caldicott Committee and chaired by Fiona Caldicott which dealt with the use of Patient Identifiable Information held by NHS organisations.

The idea of a Guardian was to have in each NHS organisation a senior person responsible for the oversight of the arrangements in that organisation for the use and sharing of clinical information. Subsequent work extended the requirement in 2002 to appoint Guardians into councils with social services responsibilities (Local Authority Circular LAC 2002/2).

In 2005 an elected body was created made up of Caldicott Guardians from organisations involved in the provision of health and social care services in the United Kingdom. It was set up to facilitate the sharing of good confidentiality practice and the promotion of a national approach to confidentiality and information sharing.
