Abstract

OBJECTIVES:

To describe the length of time National Institute for Health and Care Excellence (NICE) clinical guidelines have remained valid.

STUDY DESIGN AND SETTING:

The present study is a survival analysis of a cohort of published NICE clinical guidelines. The National Health Service in England and Wales uses NICE clinical practice guidelines as a reference for treatment and care of individuals. They need to be updated as new evidence arises, to remain credible and relevant, and are currently assessed 3 years after publication.

RESULTS:

Survival analysis suggested that about 86% of guidelines are still up-to-date 3 years after their publication. The median life span was 60 months (95% confidence interval: 51, 69).

CONCLUSION:

These findings are similar to those in other studies of the life span of guidelines. Efficient mechanisms must be in place to detect the minority of guidelines that become outdated quickly.
