To describe the length of time National Institute for Health and Care Excellence (NICE) clinical guidelines have remained valid.
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.
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).
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 Efficient mechanisms must be in place to detect the minority of guidelines that become outdated quickly.
描述国家卫生与保健优化研究所（NICE）临床指南的有效期有多长。
本研究是对一组已发表的 NICE 临床指南进行的生存分析。英格兰和威尔士的国民保健制度（NHS）将 NICE 临床实践指南用作治疗和护理个人的参考。随着新证据的出现，它们需要进行更新，以保持可信性和相关性，目前在发布后 3 年内进行评估。
生存分析表明，大约 86%的指南在发布 3 年后仍然是最新的。中位寿命为 60 个月（95%置信区间：51，69）。
这些发现与其他指南寿命研究的结果相似。必须建立有效的机制来发现少数迅速过时的指南。
