2 Notes on the scope of the guidance
NICE guidelines are developed in accordance with a scope that defines what the guideline will and will not cover. The scope of this guideline is available (see 'How this guidance was produced').
How this guideline was developed
NICE commissioned the National Clinical Guideline Centre for Acute and Chronic Conditions to develop this guideline. The Centre established a Guideline Development Group (see appendix A), which reviewed the evidence and developed the recommendations. An independent Guideline Review Panel oversaw the development of the guideline (see appendix B).
There is more information about how NICE clinical guidelines are developed on the NICE website. A booklet, 'How NICE clinical guidelines are developed: an overview for stakeholders, the public and the NHS' is available.
