摘要目的 分析我国区域医疗信息化研究领域内合著群体的规模、范围和主要研究内容,掌握该领域中科研人员、机构、地区间的合作情况.方法 在中国期刊全文数据库、万方数据库、PubMed中检索相关文献,运用文献计量学、共词分析、社会网络分析法进行分析.结果 ①共筛选出11 482篇相关文献,相关作者16 449位;平均每篇1.43个作者,每个作者0.70篇文献.合著7741篇(占67.42％).文献数量和合著情况随时间呈上升趋势.②构建了由150位高产作者组成的合著网络图,最大的成分包含43位作者(28％,43/156).57位(37％)作者中间中心度＞0.③凝聚子群分析发现了230个2-plexes.其中,65个2-plexes规模≥4.多数2-plexes之间存在重叠和合作,其中军队机构合作广泛,集中了大量区域医疗信息化研究人才.E-I Index=-0.901,表明国内该领域中派系林立程度小,关系趋向于发生在群体之内.④全国各省市之间建立了合作网络,北京、广东、江苏、湖北为研究的核心地区.⑤作者之间的平均距离=3.155,符合小世界特征.⑥最大网络成分的研究内容可以归纳为3类:医院信息系统(HIS)相关的研究,与电子病历相关的研究,区域医疗信息化相关的研究.结论 虽然我国区域医疗信息化研究领域的研究者和科研成果分布广泛,总体合作呈上升趋势,但合作群体规模小,仍需进一步拓展合作,政策制定者和相关研究者可参考相关信息,促进合作,提高区域医疗信息化研究和建设的能力.

abstractsObjective To reveal the status quo and emerging issues of co-authorship in regional health informatization research community in China.Methods The terms or keywords describing and covering regional health informatization were used to search the most relevant literatures about the subject in CNKI,Wanfang database and PubMed.Software tools were used to extract bibliographic,Social network analysis (SNA);co-authorship,and co-word analysis were used in this study.Results ①11,482 articles with 16,449 authors in the period of 1984-2013 were found.Each publication has an average of 1.43 authors,and each author has 0.70 publications.The number of coauthored literature was 7741 (67.42 ％).Both production and collaboration have been growing steadily.② Coauthored knowledge network was build which composed by 150 high-yielding Authors.The largest component comprises 43 authors(28％,43/156).The intermediate centrality of 57 authors were above 0.③ 230 2-plexes were found,and 65 2-plexes scale was 4 and over;and there was overlap among them.There were extensive cooperation between the military institutions,a large number of regional health information technology research talent were found in army research institutes..Cohesive subgroups density showed an E-I index=-0.901,which indicated that factionalism was comparatively weaker in this field,and the relationship tended to occur among subgroups.④ Cooperative network was established between the provinces and municipalities.Beijing,Guangdong,Jiangsu,Hubei were the core area.⑤ The average distance between the author=3.155,and it consistent with the small-world characteristics.⑥ The largest component of the network research can be summarized into three categories:HIS-related research,electronic medical records related research,and regional health informatization related research.Conclusions Although such collaboration is growing steadily,the collaboration behavior about regional health informatization study needs to be enhanced.Policy makers and researchers can refer to the relevant information and promote cooperation,improve the capacity of regional health information research and construction.
