Delirium is a reversible impairment of metabolism in the human brain. Early detection is important, and an effective screening tool for nurses is crucial. The Delirium Observation Screening (DOS) scale is one such screening tool; however, its diagnostic test accuracy has not yet been thoroughly examined. This study, therefore, aimed to evaluate the accuracy of the scale through a systematic review and meta-analysis. In July 2019, a search was conducted in the MEDLINE, CINAHL, Embase, and PsycARTICLES databases, and following a review against pre-defined eligibility criteria, eight studies were finally included. The quality assessment tool of diagnostic accuracy studies was applied to each study and a hierarchical regression model was used to calculate the pooled estimates of sensitivity (90%; 76%-97%, CI 95%) and specificity (92%; 88%-94%, CI 95%). The findings indicated a high diagnostic test accuracy for the DOS scale.
谵妄是人类大脑中一种可逆的代谢障碍。早期检测很重要，对护士来说，一种有效的筛查工具至关重要。谵妄观察筛查（DOS）量表就是这样一种筛查工具；然而，其诊断测试准确性尚未得到充分检验。因此，本研究旨在通过系统评价和荟萃分析评估该量表的准确性。2019年7月，在MEDLINE、CINAHL、Embase和PsycARTICLES数据库中进行了检索，根据预先定义的纳入标准进行审查后，最终纳入了八项研究。将诊断准确性研究的质量评估工具应用于每项研究，并使用分层回归模型计算敏感性（90%；76%-97%，95%CI）和特异性（92%；88%-94%，95%CI）的合并估计值。研究结果表明，DOS量表具有较高的诊断测试准确性。
