目的 分析急性缺血性卒中后认知障碍预测模型的研究现状，为相关研究的发展及应用提供参考。 方法 计算机检索PubMed、Web of Science、Ovid、EBSCOhost、中国知网、万方、维普数据库中关于急性缺血性卒中后认知障碍预测模型的文献，进行总结与分析，检索时限为建库至2022年9月。 结果 共检索获得8个预测模型，国外和国内各4个，主要用于预测轻型急性缺血性卒中患者3~6个月是否发生认知障碍。预测模型纳入的危险因素主要包括一般人口学资料和影像学指标等不可干预因素。预测模型均是通过多因素Logistic回归分析构建，且尚未被应用于护理工作。 结论 急性缺血性卒中后认知障碍预测模型预测效能较好，但研究较为单一，建议结合临床实际情况，增加可干预因素研究，完善研究设计，应用于护理工作，为高危人群的识别、预防和干预提供科学参考依据。

Objective To analyze the status of predictive models for cognitive impairment after acute ischemic stroke and provide a reference for the development and application of related research. Methods The databases of PubMed,Web of Science,Ovid,EBSCOhost,CNKI,Wanfang and VIP were searched for literature on prediction models of cognitive impairment after acute ischemic stroke from the inception up to September 2022. Results A total of 8 prediction models were retrieved,including 4 domestic models and 4 abroad models,which were mainly used to predict whether cognitive impairment occurred in patients with mild acute ischemic stroke for 3 to 6 months.The risk factors included in the prediction model mainly included non-intervening factors such as general demographic data and imaging parameters.Predictive models were developed by multivariate logistic regression analysis and had not been applied to nursing work. Conclusions The predictive model of cognitive impairment after acute ischemic stroke has a good predictive effect,but the study is relatively simple.It is recommended to increase the study of intervenable factors,improve the study design,promote the application in nursing work,and provide a scientific reference for the identification,prevention and intervention of high-risk groups in combination with the actual clinical situation.
