2010—2020年脓毒症研究文献计量学分析

Bibliometrics analysis of the research progress on sepsis from 2010 to 2020

目的:了解脓毒症的研究现状和发展趋势,为该领域后续研究提供参考依据。方法:在Web of Science数据库检索脓毒症相关文献,使用科学引文索引扩展版(Science Citation Index Expanded,SCI-E)提取并分析数据,纳入文献类型为论著。对文献概况、国家和地区、机构、作者、文献来源出版物、文献研究方向、被引频次、影响因子、H指数和关键词等进行分析。结果:共纳入Web of Science数据库2010—2020年发表的脓毒症相关文献10965篇,美国发文量居首位(3318篇,30.260%),中国发文量居第2位(2404篇,21.924%);发文量最多的机构为匹兹堡大学(222篇,2.025%);发文量居首位的作者为荷兰阿姆斯特丹大学的Tom van der Poll(89篇,0.812%);脓毒症相关文献涉及的主要学科为普通内科学(2872篇,26.192%)、免疫学(1171篇,10.679%)、实验医学(963篇,8.782%)、外科学(887篇,8.089%)和儿科学(819篇,7.469%)等。脓毒症相关文献刊发数量居前10位的期刊2019年影响因子平均为5.252,刊发数量占此研究检索结果的21.61%(2369/10965)。此研究检索结果中,美国的H指数为124,文献总被引用114594次,平均每项被引33.78次,H指数和被引频次明显高于其他国家。VOSviewer软件分析结果表明,脓毒症相关文献的关键词主要集中于"疾病相关""发病机制相关""诊治相关""实验研究相关""预后相关"等。结论:2010—2020年脓毒症相关文献发文量以美国、中国和德国最多,其中中国发文量增速最快。近十余年,中国脓毒症相关文献总量位居世界第2位,且中国2020年单年发文量已超过美国跃居全球首位,但文献质量与西方国家文献仍存在较大差距。

Objective To investigate the current research and development trend of sepsis,so as to provide reference for future studies.Methods Sepsis-related articles were retrieved from the Web of Science database,extracted and analyzed on the basis of the Science Citation Index Expanded(SCI-E).The included articles were research articles.Then,literature overview,countries and regions,institutions,authors,literature source publications,literature research direction,citation frequency,impact factors,H index and key words were analyzed.Results From 2010 to 2020,a total of 10965 articles were collected from the Web of Science database.The country with the largest number of publication was the United States(3318 papers,30.260%),followed by China(2404 papers,21.924%).The institution with the largest number of publication was University of Pittsburgh(222 papers,2.025%).Meanwhile,the author with the most published articles was Tom van der Poll(89 papers,0.812%)from University of Amsterdam in the Netherlands.The main subjects associated with sepsis were internal medicine(2872 papers,26.192%),immunology(1171 papers,10.679%),experimental medicine(963 papers,8.782%),surgery(887 papers,8.089%)and pediatrics(819 papers,7.469%).In 2019,the average impact factor of the top ten journals based on the number of publication was 5.252,and articles from the top ten journals accounted for 21.61%(2369/10965)of the retrieval results.The H index of American authors was 124,with a total citation frequency of 114594 times and an average of 33.78 times per item,whose H index and citation frequency were remarkably higher than those in other countries.According to the results of VOSviewer software,the key words associated with sepsis were mainly"disease related","pathogenesis related","diagnosis and treatment related","experiment related",and"prognosis related".Conclusions The United States,China,and Germany published the most sepsis-related articles from 2010 to 2020,with the fastest increase in publication in China.Although China had the second largest number of publication in recent ten year,and the largest volume of publication in 2020,there is still a certain quality gap of the publications between China and Western countries.
