摘要
目的用可视化方法系统、全面、直观地揭示和比较中外循证医学领域作者、所处位置、领域共同体及其演化,进一步揭示循证医学学科结构及其演绎,更好了解循证医学学科现状和人才梯队,规划学科和领域发展,为学科建设和培养循证医学人才队伍提供参考信息。方法构建中外高被引作者同被引矩阵和作者合作矩阵,采用整体网络分析法进行分析,将所得数据用UCINET软件实现可视化。结果循证医学的研究主要集中在发达国家和地区的大学。国外以SACKETT DL,GUYATT GH和MANCHIKANTI L为中心,先后发展成3个共同体,;被引作者主要分布在2003年前。国内循证医学核心作者可划分为9大学术共同体,在各个时段都有高被引作者出现,反映出梯队的传承。受时空限制,SCI核心作者的合作较松散;国内核心作者的合作关系结构分成4个部分,21个派系,但各部分的演变不同,网络核心作者主要在四川大学中国循证医学中心。结论国际循证医学核心研究者主要集中在发达国家的知名大学,加拿大的McMaster大学是循证医学的源头和制高点。国内循证医学的核心作者也主要分布在大学,四川大学中国循证医学中心是中国循证医学的培训基地和学术制高点。国外以SACKETT DL,GUYATT GH和MANCHIKANTI L为中心,先后发展成3个共同体。国内以李幼平、刘鸣和张鸣明为核心,先后发展成9大学术共同体;构建的循证医学合作网由4大部分组成,其中最重要和完善的合作子网是以李幼平为领导,刘鸣、张鸣明、李静、王莉、吴泰相、刘关键为核心的循证医学合作网。
Objective To investigate the output of evidence-based medicine(EBM) researchers in China and elsewhere by examining the EBM domains they work within and the networks that exist among them;using visualization methods to analyze these relationships.This maps the current situation and helps with the identification of areas for future growth.Method We used co-citation matrixes with Pathfinder networks and hierarchical clustering algorithms,and constructed a co-author matrix which were analyzed with a whole network approach.The analyzed matrixes were visualized with the UCINET program.Result Much of the development of EBM has been centered around three authors,David Sackett,Gordon Guyatt and L Manchikanti,within three different clusters.The main authors of EBM articles in China were divided into nine academic domains.The relations among core authors of articles indexed by the Science Citation Index(SCI) was loose.There was a stronger co-authorship network among core authors in the Chinese literature,with three groups and 21 cliques.Nine distinct academic communities appeared to have formed around Li Youping,Liu Ming and Zhang Mingming.Conclusion The EBM literature contains several key clusters,with universities in high-income countries being the source of the majority of articles.Outside China,McMaster University in Canada,the original home of EBM,is the dominant producer of EBM publications.In China,Sichuan University is the main source of EBM publications.The EBM cooperation network in China is comprised of three major groups,the largest and most productive in this sample is led by Li Youping with Liu Ming,Zhang Mingming,Li Jing,Wang Li,Wu Taixiang,and Liu Guanjian as central members.
