The National Institute for Clinical Excellence (NICE) was one of the better known of the new agencies but this did not prevent it merging, in April 2005, with Health Development Agency to create this new body. It retains the NICE acronym.
The purpose is to create a single organisation for excellence in practice in health. It offers national guidance on the promotion of good health and the treatment of ill health. It will concentrate on three areas of health: public health; health technologies; and clinical practice. For this purpose it has created three centres: the Centre for Public Health Excellence; the Centre for Health Technology Evaluation; and the Centre for Clinical Excellence.
