目的调查中国临床实践指南的更新周期、方法和步骤。方法在WanFang Data、VIP、CNKI中,以“指南、指引”为检索词在题名中进行检索,在CBM数据库中以“指南”为主题词进行检索,纳入符合标准的文献,统计分析其更新情况。结果共纳入指南380个,报道已更新的指南仅有38个(10%),平均更新周期为5.1年,更新周期最长为10年,最短为1年;38个已更新指南中有8个(2%)进行过多次更新,其平均更新次数为3次,平均更新周期为4.9年。在342个未更新过的指南中,提及未来会更新的指南有42个(12%)。将已更新指南按临床用途分:预防类指南1个(0.3%),更新周期为4年;治疗类指南8个(2%),平均更新周期为4.3年;防治指南5个(1%),平均更新周期6.8年;诊疗类指南18个(5%),平均更新周期5.3年;技术类指南4个(1%),平均更新周期为5.5年;综合指南2个(0.5%),平均更新周期为2.5年。所有指南中,有40个(10%)在文中描述了更新方法。结论分析国际与国内指南更新情况发现,中国临床实践指南更新比例低,更新周期长,且参差不齐;更新方法和步骤报道不规范,描述不充分;不同类别的指南和不同机构制定的指南更新情况差异大。
