Critical care medicine research is reported in major medical journals that can be accessed via computerized search engines such as PubMed (National Library of Medicine) or Web of Science (Thomson ISI [Institute for Scientific Information]). The crediting of report citations to specific journals or individuals is a rapidly developing and highly controversial evaluative process.
We conducted a citation analysis to measure the research and publication accomplishments of critical care medicine investigators, by tallying their numbers of published reports and numbers of citations to their reports. Major investigators were identified from the author indexes of major critical care medicine publications. From the Web of Science the number of publications and citations of their works were determined for 224 investigators for the period 1997 through August 2003. We calculated the individual researcher's "impact factor" by dividing the number of citations (made by other researchers to a given researcher's reports) by the number of articles that researcher had published. To estimate which countries are producing the most research on mechanical ventilation, we studied the abstract books from the 2001, 2002, and 2003 American Thoracic Society annual international conferences and tallied the number of posters (pertaining to mechanical ventilation) from the various countries. We then calculated a "country factor" as the number of posters per million population of the source country.
We considered 44, 576 citations in 3,755 publications. Using criteria selected to recognize original works, J L Vincent published the greatest number of reports (129). M A Matthay received the most citations (2,056). G U Meduri had the highest impact factor (25.32). There was a balance between the number of leading investigators from Europe and North America. Relative to its population size, Canada warrants leadership acknowledgement in critical care medicine, considering its number of leading investigators and poster presentations.
From criteria selected to attribute original work to specific authors we identified 20 leading critical care medicine investigators, as measured by number of publications, citations, and impact factors. We also report a country factor based on posters (on mechanical ventilation) presented at the 2001-2003 international conferences of the American Thoracic Society.
重症医学研究成果发表在一些主要医学期刊上，可通过诸如PubMed（美国国立医学图书馆）或Web of Science（汤姆森ISI[科学信息研究所]）等计算机搜索引擎获取。将报告引用归功于特定期刊或个人是一个快速发展且极具争议的评估过程。
我们进行了一项引文分析，通过统计重症医学研究人员发表报告的数量及其报告被引用的次数，来衡量他们的研究和出版成就。主要研究人员从主要重症医学出版物的作者索引中确定。从Web of Science获取了1997年至2003年8月期间224名研究人员的作品发表数量和被引用次数。我们通过将（其他研究人员对给定研究人员报告的）引用次数除以该研究人员发表的文章数量来计算单个研究人员的“影响因子”。为了估计哪些国家在机械通气研究方面成果最多，我们研究了2001年、2002年和2003年美国胸科学会年度国际会议的摘要集，并统计了来自各个国家的（与机械通气相关的）海报数量。然后我们计算了一个“国家因子”，即来源国每百万人口的海报数量。
我们考虑了3755篇出版物中的44576次引用。按照用于识别原创作品的标准，J·L·文森特发表的报告数量最多（129篇）。M·A·马泰获得的引用次数最多（2056次）。G·U·梅杜里的影响因子最高（25.32）。欧洲和北美的主要研究人员数量相当。就其人口规模而言，考虑到其主要研究人员数量和海报展示数量，加拿大在重症医学领域应得到领先地位的认可。
根据用于将原创作品归功于特定作者的标准，我们确定了20位重症医学领域的主要研究人员，衡量标准为发表数量、引用次数和影响因子。我们还报告了基于2001 - 2003年美国胸科学会国际会议上展示的（关于机械通气的）海报得出的国家因子。
