The Caldicott Committee's Report on the Review of Patient-Identifiable Information, usually referred to as the Caldicott Report was a review commissioned in 1997 by the Chief Medical Officer of England due to increasing worries concerning the use of patient information in the National Health Service in England and Wales and the need to avoid the undermining of confidentiality because of the development of information technology in the NHS, and its ability to propagate information concerning patients in a rapid and extensive way.
