2.1. What is a NICE clinical guideline?

NICE clinical guidelines are recommendations for the care of individuals in specific clinical conditions or circumstances within the NHS – from prevention and self-care through primary and secondary care to more specialised services. We base our clinical guidelines on the best available research evidence, with the aim of improving the quality of health care. We use predetermined and systematic methods to identify and evaluate the evidence relating to specific review questions.

NICE clinical guidelines can:

• provide recommendations for the treatment and care of people by health professionals
• be used to develop standards to assess the clinical practice of individual health professionals
• be used in the education and training of health professionals
• help patients to make informed decisions
• improve communication between patient and health professional

While guidelines assist the practice of healthcare professionals, they do not replace their knowledge and skills.

We produce our guidelines using the following steps:

• Guideline topic is referred to NICE from the Department of Health
• Stakeholders register an interest in the guideline and are consulted throughout the development process.
• The scope is prepared by the National Clinical Guideline Centre (NCGC)
• The NCGC establishes a guideline development group
• A draft guideline is produced after the group assesses the available evidence and makes recommendations
• There is a consultation on the draft guideline.
• The final guideline is produced.

The NCGC and NICE produce a number of versions of this guideline:

• the full guideline contains all the recommendations, plus details of the methods used and the underpinning evidence
• the NICE guideline lists the recommendations
• the quick reference guide (QRG) presents recommendations in a suitable format for health professionals
• information for the public (‘understanding NICE guidance’ or UNG) is written using suitable language for people without specialist medical knowledge.

This version is the full version. The other versions can be downloaded from NICE at www.nice.org.uk

2.2. Who developed this guideline?

A multidisciplinary Guideline Development Group (GDG) comprising professional group members and consumer representatives of the main stakeholders developed this guideline (see section on Guideline Development Group Membership and acknowledgements).

The National Institute for Health and Care Excellence funds the National Clinical Guideline Centre (NCGC) and thus supported the development of this guideline. The GDG was convened by the NCGC and chaired by Professor Philip Conaghan in accordance with guidance from the National Institute for Health and Care Excellence (NICE).

The group met every 6 weeks during the development of the guideline. At the start of the guideline development process all GDG members declared interests including consultancies, fee-paid work, share-holdings, fellowships and support from the healthcare industry. At all subsequent GDG meetings, members declared arising conflicts of interest, which were also recorded (Appendix B).

Members were either required to withdraw completely or for part of the discussion if their declared interest made it appropriate. The details of declared interests and the actions taken are shown in Appendix B.

Staff from the NCGC provided methodological support and guidance for the development process. The team working on the guideline included a project manager, systematic reviewers, health economists and information scientists. They undertook systematic searches of the literature, appraised the evidence, conducted Meta-analysis and cost effectiveness analysis where appropriate and drafted the guideline in collaboration with the GDG.

2.3. What this guideline covers
