基于文献计量学的我国器官捐献学科建设现状分析与展望

Current research status and prospect of organ donation discipline construction in China:a bibliometric analysis

目的提炼和总结我国器官捐献学科的研究现状及学科发展趋势变化。方法以2018年1月1日至2022年12月31日中国知网学术期刊全文数据库(CNKI)和Web of Science核心合集数据库收录的有关器官捐献研究的中文和英文文献为样本,应用CiteSpace软件从发文量、关键词、期刊来源分布、核心作者合作网络、主要研究机构、重点文献被引等方面进行可视化分析。结果2018年至2022年共发表792篇,年均发文量达158篇,趋势呈现出迅速上升态势,以研究生毕业论文形式发表的论文达182篇(占23%)。常见的研究关键词包括器官移植、脑死亡、心死亡、意愿/认知/态度、法制、影响因素/危险因素、感染/并发症、器官获取组织、预后/质量、大学生/医学生教育、体外膜肺氧合、儿童、缺血-再灌注损伤、供者来源性感染、伦理、扩大标准供者、护理、协调员等,关键词聚类热点呈现围绕“器官捐献”这一主题向各个学科领域展开的趋势。研究成果发表刊物具有多元性和多样性的特点,研究内容以医学为核心,并跨越多个学科领域。大型器官移植机构团队发表的研究数量占绝大多数,机构内形成了相对紧密的合作关系;各机构间的合作强度较低,各作者之间的合作关系也较为松散,尚未能形成紧密的学术合作关系。全球“器官捐献”主题研究发文量前5的国家分别是美国(940篇)、英国(377篇)、西班牙(263篇)、加拿大(241篇)、中国(181篇),表明中国研究者在国际学术舞台上的发声已逐渐被认可。结论从近年文献发表的数量和内容来看,“器官捐献”在我国学术领域已有一定的研究基础,是我国多个学界关心和广泛研究的课题之一,且相关的研究问题具有跨界、多元和多样的特点。

Objective To refine and summarize the research status and development trend of organ donation discipline in China.Methods Relevant Chinese and English literatures related to organ donation were searched from China National Knowledge Infrastructure(CNKI)and Web of Science core collection database from January 1,2018 to December 31,2022.Visual analysis was performed by the CiteSpace software from the number of published articles,keywords,journal source distribution,cooperation network of core authors,main research institutions,and citation of key literatures,etc.Results A total of 792 articles were published from 2018 to 2022,with an average annual number of 158 articles,which showed a rapidly upward trend.Among them,182 articles were published in the form of postgraduate dissertation,accounting for 23%.Common keywords included organ transplantation,brain death,cardiac death,willingness/cognition/attitude,legal system,influencing factor/risk factor,infection/complication,Organ Procurement Organization,prognosis/quality,education for college students/medical students,extracorporeal membrane oxygenation,children,ischemia-reperfusion injury,donor-derived infection,ethics,expended criteria donor,nursing and coordinator,etc.Keyword clustering hotspots focused on the theme of“organ donation”and branched into multiple disciplines.The publications of research results were characterized with pluralism and diversity,and the research contents were centered on medicine and spanned a wide range of disciplines.A large proportion of researches were published by the teams from large-scale organ transplantation institutions,and relatively close cooperative relationship was formed within the institutions.However,the intensity of cooperation among different institutions was relatively low,and the cooperative relationship among authors was insufficient,which failed to form an intimate academic network.The top five countries worldwide regarding the number of published articles were the U.S.(n=940),U.K.(n=377),Spain(n=263),Canada(n=241)and China(n=181),indicating that the achievements of Chinese researchers have been gradually recognized in the international academic community.Conclusions From the quantity and content of published articles in recent years,“organ donation”has laid certain research foundation in China.It is one of the topics concerned and widely studied by multiple academic communities in China.Relevant research issues have multidisciplinary,plural and diverse characteristics.
