基于Web of Science检索和文献计量学方法的危重症医学热点初步研究

目的 分析全球危重症医学研究现状，挖掘该领域的研究热点。方法 检索2007－2017年危重症医学领域的研究论文，利用Web of Science、期刊引证报告（JCR）和Echarts软件等对其进行综合分析，采用VOSviewer软件提取与分析研究范围内论文的题目和摘要，并选择出高频关键词。同时分析2007－2017年危重症医学研究领域论文产出有重要贡献的国家变化。结果 符合入选标准的论文共51 928篇，其中论著45 696篇、综述6 232篇。通过生成高频关键词热图，发现当前的危重症医学术语热点包括管理、功能、观察研究、创伤、试验。2007－2017年，美国是危重症医学研究领域论文产出最多的国家。2007年和2017年，美国论文数量分别占论文总数的43.74%（1 872/4 280）和46.78%（2 288/4 891）。结论 当前的危重症医学术语热点包括管理、功能、观察研究、创伤、试验，美国在全球危重症医学研究领域依然占据首席地位。
Objective To analyze the current global status of critical care medicine and to explore the research focus. Methods The papers concerning critical care medicine published between 2007 and 2017 were retrieved and analyzed using Web of Science, Journal Citation Report (JCR) and Echarts software. The titles and abstracts were extracted and analyzed using VOSviewer software to identify the high frequency key words. Meanwhile, the changes of countries with important contribations in the output ranking of papers were analyzed in the field of critical care medicine research from 2007 to 2017. Results A total of 51 928 papers met the inclusion criteria, and 45 696 were original articles and 6 232 were reviews. The high frequency key word thermogram showed that the focuses of critical care medicine terminology included management, function, observational study, trauma and trial. The United States remained the leading role in critical care medicine paper output from 2007 to 2017. In 2007 and 2017, the paper number of United States accounted for 43.74% (1 872/4 280) and 46.78% (2 288/4 891) of total papers, respectively. Conclusion The management, function, observational study, trauma and trial are focuses in the field of critical care medicine research and the United States remains the leading role in critical care medicine research
