基于文献计量分析软件VOSviewer的腹膜透析研究现状的可视化分析

Visual analysis of current research status of peritoneal dialysis based on VOSviewer

目的旨在探讨近十年腹膜透析的研究现状和研究热点。方法通过Web of Science核心合集的科学引文扩展数据库检索2010年~2019年关于腹膜透析的相关文献,应用文献计量学的研究方法和文献计量分析软件VOSviewer软件对期刊、作者、研究机构、关键词等进行提取分析及可视化展示,分析腹膜透析研究领域的热点及发展历史。结果本研究共筛选纳入6864篇研究。总体而言,近十年腹膜透析研究产出波动式增长。其中美国在该领域的研究保持领先地位,其发文量、期刊分布、被引频次及H指数及基金资助产出均排名前列。我国腹膜透析研究发展迅速,研究机构及作者主要集中在中国,但国内研究机构与国际相关机构合作较少,研究作者间合作较为分散。腹膜透析研究热点主要集中在治疗预后、病理机制、并发症、透析质量及生活质量评价研究。结论采用文献计量学方法进行研究,可以更加清晰、直观地了解到全球腹膜透析的研究现状和热点。

Objective To evaluate the current research status and research hotspots of peritoneal dialysis in the past decade.Methods In the Science Citation Index Expanded database of the Web of Science,this study applied the relevant researches on peritoneal dialysis from 2010 to 2019 to extract and analyze according to journals,authors,research institutions,keywords by bibliometrics and VOSviewer software.We analyzed the hotspots and development history of the research field of peritoneal dialysis by visual display.Results A total of 6,864 studies were retrieved.In general,the output of peritoneal dialysis research has fluctuated in the past decade.Number of studies on peritoneal dialysis ranked top 1 country is the United States,and the publication volume,journal distribution,frequency of citations,H index and fund-funded output of peritoneal dialysis research in the United States are all ranked in the forefront.The research on peritoneal dialysis is developing rapidly in China,and the research institutions and authors are mainly concentrated in our country.But domestic research institutions have little cooperation with related international institutions,and the cooperation between research authors is relatively scattered.The hotspots of peritoneal dialysis research mainly focus on the evaluation of treatment prognosis,pathological mechanisms,complications,dialysis quality and quality of life.Conclusions Using bibliometric methods,we can get a clearer and more intuitive understanding of the current of global research status and hotspots of peritoneal dialysis.
