Clinical guidelines: ways ahead.

Abstract

Clinical guidelines are essential in promoting the implementation of evidence-based practice within the NHS. But there are two broad schools of thought about their development and implementation: the first argues that guidelines should be entirely evidence-based and tolerates a degree of complexity which may make the guideline impractical; the second argues that we need simple guidelines, and sacrifices the strength of evidence in favour of ease of application and dissemination. Both arguments have merits and flaws, which are discussed, and ways to integrate the strengths of both are considered.
