NICE clinical guidelines are recommendations about the treatment and care of people with specific diseases and conditions in the NHS in England and Wales.
The guideline was developed by the National Collaborating Centre for Mental Health and the National Collaborating Centre for Primary Care. The Collaborating Centres worked with a group of healthcare professionals (including consultants, GPs and nurses), patients and carers, and technical staff, who reviewed the evidence and drafted the recommendations. The recommendations were finalised after public consultation.
The methods and processes for developing NICE clinical guidelines are described in the guidelines manual.
This guideline updates and replaces NICE clinical guideline 22 (published published December 2004; amended April 2007).
