Objective:To evaluate the impact of clustering nursing on stroke-related pneumonia by Meta-analysis, and provide a scientific basis for improving the prognosis of stroke patients.Methods:We searched in Wanfang database, CNKI, China Biomedical Literature database, PubMed, Web of Science, EMbase, and Cochrane Library database. The objects were patients with stroke. The trials (RCTs) included randomized controlled was about clustering nursing intervention for stroke-related pneumonia. The search period is from the construction of the database to January,2018. The main outcome indicators were the incidence of stroke-related pneumonia, the incidence of aspiration, and the hospitalization, the secondary outcome indicators were hospitalization costs, mortality, and swallowing function. Two researchers independently screened the literature, extracted the data, and evaluated the quality of the included studies. The quality evaluation used the Cochrane Collaboration's bias risk assessment tool. The data was analyzed using RevMan 5.3 statistical software. The continuous variables used standardized mean difference (SMD) and 95%CI as the effect indicators. The dichotomous variables used odds ratio (OR) and 95%CI as the effect indicators. If the homogeneity between the studies was good (P≥0.1, I2≤50%), select the fixed effect model, if there was heterogeneity between these studies (PI2>50%), analyze the source of heterogeneity, and if there was no clinical heterogeneity, choose a random effects model.Results:A total of 11 clinical randomized controlled trial literatures were finally included. They were all in Chinese, with a total of 1 048 patients. Meta analysis results showed that the incidence of SAP in the cluster care group was[OR=0.31, 95%CI (0.22,0.44), POR=0.19, 95%CI (0.10,0.33), PSMD=-0.82, 95%CI (-1.09,-0.54), PSMD=-5.38, 95%CI (-6.02,-4.74), PP
