目的 针对脑卒中后谵妄（post stroke delirium,PSD）的发生率进行Meta分析，为有效预防PSD提供科学依据。方法 检索中国知网、万方、维普、中国生物医学数据库、Pubmed、Web of Science、Embase、CINAHL、Scopus、Cochrane Library、PsycINFO等数据库中PSD的相关研究，检索限制为建库起至2023年10月1日。采用Stata 17.0软件对纳入文献进行Meta分析。结果 共纳入23篇文献，共9738例卒中患者，PSD的总体发生率为21%[95%CI（18%~25%）]。女性、欧洲、出血性卒中、全前循环梗死、评估工具为谵妄评定量表和发表时间在2014-2023年（与2003-2013年相比）的PSD发生率更高。结论 PSD的发生率较高，医护人员应加强对女性、全前循环梗死、出血性卒中患者的关注，制订针对性预防策略，以降低PSD发生率。

Objective A meta-analysis of the incidence of post stroke delirium (PSD) was conducted to provide reference for the effective prevention of PSD. Methods Literatures related to PSD were searched in CNKI,Wanfang,cqVIP,China Biomedical Database,Pubmed,Web of Science,Embase,CINAHL,Scopus,Cochrane Library,PsycINFO and other databases. The retrieval time was from the inception to October 1,2023. Stata 17 software was used for meta-analysis. Results A total of 23 studies were included,including 9738 stroke patients,and the overall incidence of PSD was 21% [95%CI(18%-25%)]. Results showed a higher incidence of PSD in women,Europe,hemorrhagic stroke,total anterior circulation infarction,Delirium Rating Scale (DRS),and publication in 2014-2023 (compared with 2003-2013). Conclusion The incidence of PSD is relatively high. Medical staff should pay more attention to women,total anterior circulation infarction and hemorrhagic stroke patients,and formulate targeted prevention strategies to reduce the incidence of PSD.
