基于CiteSpace的血液透析相关感染文献的可视化分析

Visual Analysis of Hemodialysis-related Infection Literature Based on CiteSpace

目的基于CiteSpace对2012-2021年血液透析相关感染文献进行可视化图谱分析,分析其研究现状、热点及变化趋势。方法以hemodialysis、infection为主题,检索Web of Science核心数据库相关文献,检索时间设置为2012年1月1日-2021年12月30日。应用CiteSpace 5.8.R3软件对作者、机构、国家、关键词、分类等进行可视化分析。结果共纳入3716篇相关文献。从发文趋势可知,血液透析相关感染一直为研究重点,近10年年发文量总体呈增长趋势,且年发文量维持在300篇以上。从国家与机构可知,排名前3的国家分别是美国、中国、日本,且美国中介中心性最高,而研究机构中以多伦多大学发文量最多。Fabrizio Fabrizi是发文量最多的作者,其主要研究方向为血液透析患者丙型病毒性肝炎感染。对关键词进行可视化分析,血液透析、感染、终末期肾病、死亡率、危险因素、预防、血管通路为高频关键词。关键词突现中肝炎、抗病毒治疗可能为未来研究重点。科目分类中社会科学、机械工程中心性较高。结论血液透析相关感染近几年发文量升高,丙型病毒性肝炎感染一直为研究热点,抗病毒治疗的研究未来仍具有发展前景。

Objective To analyze the literature on hemodialysis-related infections from 2012 to 2021 based on CiteSpace,and to analyze the research status,hotspots and trends.Methods With the theme of hemodialysis and infection,the relevant literatures in the core database of Web of Science were retrieved.The retrieval time was set from January 1,2012 to December 30,2021.CiteSpace 5.8.R3 software was used to visually analyze authors,institutions,countries,keywords,classifications,etc.Results A total of 3716 related literatures were included.From the analysis of the trend of publications,hemodialysis-related infections had always been the focus of research.In the past 10 years,the annual number of publications had generally shown an increasing trend,and the annual number of publications had remained at more than 300.From the perspective of countries and institutions,the top three countries were the United States,China and Japan,and the United States had the highest degree of intermediary centrality,while the University of Toronto had the largest number of publications among research institutions.Fabrizio Fabrizi was the author with the largest number of publications,the main research direction was hepatitis C virus infection in hemodialysis patients.Visual analysis of keywords showed that hemodialysis,infection,end-stage renal disease,mortality,risk factors,prevention,and vascular access were high-frequency keywords.Keywords burst showed that hepatitis and antiviral therapy might be the focus of future research.In the classification of subjects,the centrality of social science and mechanical engineering was higher.Conclusion The annual number of published papers on hemodialysis-related infections has increased in recent years.Hepatitis C infection has always been a research hotspot,and the research on antiviral therapy may still have development prospects.
