NICE clinical guidelines are recommendations about the treatment and care of people with specific diseases and conditions.
NICE guidelines are developed in accordance with a scope that defines what the guideline will and will not cover.
This guideline was developed by the NICE Internal Clinical Guidelines Programme. The Internal Clinical Guidelines Programme worked with a Guideline Development Group, comprising healthcare professionals (including consultants, GPs and nurses), patients and carers, and technical staff, which 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.
NICE produces guidance, standards and information on commissioning and providing high‑quality healthcare, social care, and public health services. We have agreements to provide certain NICE services to Wales, Scotland and Northern Ireland. Decisions on how NICE guidance and other products apply in those countries are made by ministers in the Welsh government, Scottish government, and Northern Ireland Executive. NICE guidance or other products may include references to organisations or people responsible for commissioning or providing care that may be relevant only to England.
This guidance updates and replaces NICE guidelines CG10 (published January 2004) and CG119 (published March 2011), and the recommendations on foot care in NICE guideline CG15 (published July 2004).
Recommendations marked  indicates that the evidence has not been reviewed since 2011.
