摘　　要：目的 调查中文系统评价(Systematic review,SR)与Cochrane SR在脑卒中领域的重复性。方法 计算机检索CNKI、WanFang Data、CBM和Cochrane Library数据库,搜集脑卒中领域发表的中文SR与Cochrane SR,检索时限均为2012年至2022年。通过提取脑卒中领域所有干预性系统评价的人群(population,P)、干预(intervention,I)、对照(comparison,C)、结果(outcome,O),分析SR的重复性,并进一步提取PICO重复的SR的基本信息和研究信息,进行描述性分析。结果 共纳入1 303篇文献,其中1 192篇中文SR,111篇Cochrane SR。重复性分析结果显示,128篇中文SR与29篇Cochrane SR在PICO方面存在重复。大部分(127/128,99.2%)中文SR的发表时间晚于Cochrane SR,重复性SR的发表年份呈逐年增长趋势。结论 我国学者开展的SR工作存在不容忽视的重复性研究问题,在注册、计划书撰写、文献检索等方法方面缺少严格的规范和引导,造成极大的资源浪费,需要进一步加强规范约束和引导,坚持问题导向和质量意识,强化SR培训,减少重复性研究。Objective To investigate the extent of overlap between Chinese systematic reviews(SRs)and Cochrane SRs in the field of stroke.Methods The CNKI,WanFang Data,CBM and Cochrane Library databases were searched to collect Chinese SRs and Cochrane SRs in the field of stroke published from 2012 to 2022.By extracting population(P),intervention(I),comparison(C),and outcome(O)of all interventional SRs in the stroke field to analyse the extent of overlap of SRs.The basic information and research information of SRs with overlapping PICOs were further extracted to conduct descriptive analysis.Results A total of 1303 SRs were included,involving 1192 Chinese SRs and111 Cochrane SRs in the field of stroke.The overlapping analysis found that 128 Chinese SRs overlapped with 29(26.1%)of the 111 Cochrane SRs.Most(127/128,99.2%)Chinese SRs were published later than Cochrane SRs.The year of publication of overlapping SRs showed a trend of increasing year by year.Conclusion The SR work carried out by scholars in China has the problem of overlapping studies that cannot be ignored,and the lack of strict regulation and guidance in methods such as registration,protocol writing,and literature search has resulted in a great waste of resources.It is necessary to further strengthen regulatory constraints and guidance,adhere to problem orientation and quality awareness,strengthen SR training,and reduce overlapping research.
