对于护理随机对照试验 (RCT) 的偏见风险评估的分歧差异很大. 从RCT中提取不一致的信息是系统审查中这些差异的主要原因.
科学领域:
- 护理研究 护理研究
- 证据综合 证据综合
- 方法论 方法论 方法论
背景情况:
- 偏差风险 (RoB) 评估中的差异破坏了系统性审查 (SRs) 的可信度.
- 之前没有任何研究专门评估了护理研究中的RoB评估的可靠性.
研究的目的:
- 量化ROB评估中的分歧的程度和原因.
- 专注于随机对照试验 (RCT),这些试验出现在护理领域的多个Cochrane评论中.
主要方法:
- 使用现有研究报告进行二次数据分析.
- 包括参与过多次护理科克莱恩综述的RCT.
- 分析了分歧率,并调查了潜在的原因.
主要成果:
- 在多次审查中确定了23个RCT.
- 同意度差异很大,从选择性报告的36.84%到随机序列生成的91.30%.
- 对参与者/人员 (50.00%),对结果评估 (58.82%) 和不完整的结果数据 (66.67%) 的盲目化,注意到缺乏一致性.
- 从RCT中提取不完整或不同的信息是分歧的主要驱动因素.
结论:
- 在护理SR中RoB评估的可靠性是不一致的.
- 强调需要在SR进行过程中从RCT收集更全面,更准确的数据.
