Reviewing published clinical guidelines
This is a brief summary of how NICE reviews published clinical guidelines. See all published clinical guidelines.
Published guidelines are reviewed every three years to decide if an update is needed. This review decision is informed by a number of stages of intelligence gathering, including searches for evidence, related guidance and qualitative feedback from other NICE departments, from the original National Collaborating Centre (NCC) Developers and Guideline Development Group (GDG).
1. Review process begins
Searches take place for new evidence to inform review decisions for update, that may have emerged following publication of the initial guideline.
2. Stakeholders register interest
National organisations representing patients and carers, and also health professionals involved in their care can register as stakeholders. Stakeholders are consulted as part of the review process.
