NICE 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 Clinical Guideline Centre. The Centre 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 guidelines are described in the guidelines manual.
