中国导管相关血流感染研究文献的可视化分析

目的分析国内导管相关血流感染(CRBSI)的研究现状。方法于2017年10月对中国知网(CNKI)数据库、万方数据库、CBM数据库收录的CRBSI的期刊文献以及PubMed、Cochrane Library数据库收录的国内作者的相关英文文献进行文献检索及筛选,运用Excel建立基金、期刊、发文机构频次图,使用Ucinet软件、BICOMB软件、Netdraw软件生成作者、发文机构、研究地区和关键词可视化共线网络图。结果共检索到有效文献1 451篇。CRBSI领域作者合作较多,机构间合作密切。发文机构分布中四川大学华西医院位居第一(28篇),其次为解放军总医院(16篇)和中南大学湘雅医院(15篇);基金支持以省、市、自治区项目为主;文献发表期刊以中华医院感染学杂志为主;省市间联系较为密切,主要以华东、华北、华中地区为主;关键词以"中心静脉置管"、"ICU"、"医院感染"、"集束化干预"、"护理"、"目标性监测"和"危险因素"为高频词,揭示了领域研究热点。结论目前,CRBSI已引起国内学者的广泛关注,需加强跨地区机构及个人和科研团体之间的合作,关注该领域研究热点,提升研究质量。

Visualization analysis on research literatures about catheter related bloodstream infection in China

ObjectiveTo analyze the current research status of catheter related bloodstream infection (CRBSI) in China. MethodsOn October 2017, literatures about CRBSI from China National Knowledge Infrastructure（CNKI）, Wanfang Database, China Biomedical Literature Database(CBM), PubMed, and Cochrane Library were searched and screened. Frequency diagrams of funds, periodicals, and issuing agencies were constructed by using Excel, visualized collinear network diagram of authors, issuing agencies, research area, and key words were generated by Ucinet software, BICOMB software, and Netdraw software. ResultsA total of 1 451 effective literatures were retrieved. In the research field of CRBSI, cooperation among authors and close cooperation among agencies were frequent. Distribution of issuing agencies revealed that The West China Hospital of Sichuan University ranked first (28 articles), followed by the Chinese PLA General Hospital (16 articles) and Xiangya Hospital of Central South University (15 articles); funds were mainly supported by provincial, municipal, and autonomous regional projects; literatures were published mainly in Chinese Journal of Nosocomiology, and the links between provinces and cities were relatively close, mainly in East China, North China, and Central China. The high frequency key words were "central venous catheterization", "ICU", "healthcare associated infection", "bundle intervention", "nursing", "target monitoring", and "risk factor", which revealed the hot topics in the field of research. ConclusionAt present, CRBSI has attracted wide attention of domestic scholars, cooperation between regional institutions, individuals, and research groups needs to be strengthened, research in this field needs to be focused, and quality of research needs to be improved.
