对于核心结果集 (COS) 的认识在科克伦系统审查作者中越来越多,但它们在选择结果中的使用仍然很低. 促进者包括意识和积极的看法,而障碍则涉及范围不匹配.
科学领域:
- 基于证据的医学是基于证据的医学.
- 系统审查是系统的审查.
- 健康研究方法的方法论.
背景情况:
- 核心成果集 (COS) 旨在在健康研究中规范结果选择.
- 之前的研究表明,Cochrane系统综述 (SRs) 中COS的引用率较低.
研究的目的:
- 评估Cochrane干预SR协议和完成的SR中COS的当前考虑情况.
- 确定影响作者使用COS进行结果选择的促进者和障碍.
主要方法:
- 在2022年发表的294个Cochrane SRs (协议和完成的审查) 的分析.
- 检查COS引用,搜索和结果利用的情况.
- 在线调查236名SR作者,以确定意识,促进者和障碍.
主要成果:
- 13%的SR引用了COS;5%搜索了COS.
- 相关的COS被确定为39%的SRs没有引用它们.
- 关键的促进因素包括对COS的认识 (59%) 和积极的看法 (52%).
- 障碍包括COS和SR群体/干预措施之间的范围不匹配 (29%/21%).
- 87%的作者会考虑在未来的更新中纳入缺失的核心成果.
结论:
- 自2019年以来,Cochrane SRs中对COS的考虑和意识有所增加,但采用率仍然很低.
- 提高COS利用率对于结果标准化和减少研究浪费至关重要.
- 解决范围不匹配障碍可以提高COS在证据综合中的有效使用.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
