AimsTo evaluate the diagnostic test accuracy of the Nursing Delirium Screening Scale through a systematic review and meta-analysis.DesignA systematic review with meta-analysis.Data SourcesArticles were searched systematically in the MEDLINE, EMBASE, PsycINFO, and CINAHL databases up to April 2019.Review MethodsData extraction and quality assessment were conducted using the Quality Assessment of the Diagnostic Accuracy Studies-2 tool. Pooled sensitivities, specificities, likelihood ratio, and diagnostic odds ratio for the tool were estimated and its hierarchical summary receiver-operating characteristic curve was derived through a bivariate model meta-analysis.ResultsEleven studies with a total of 2,245 patients were included in this review. The pooled estimates of sensitivity and specificity of the Nursing Delirium Screening Scale were 68.6% (95% confidence interval; 55.3%, 79.5%) and 89.4% (83.3%, 93.5%), respectively. The pooled estimate of the area under the hierarchical summary receiver-operating characteristic curve was 0.88.ConclusionUse of the Nursing Delirium Screening Scale provides moderate to high sensitivity and high specificity. This review supports the Nursing Delirium Screening Scale as a validate tool of screening for delirium.ImpactWith the best evidence of the accuracy of the Nursing Delirium Screening Scale, we recommend nursing leaders to use this easy-to-use and validated tool for daily screening of delirium in any hospital setting, which possibly contribute to an early detection of delirium and, ultimately, assist to obtain an accurate estimation of prevalence of delirium.© 2020 John Wiley & Sons Ltd.
