The bibliometrics of the anesthesiology literature has shifted substantially during the past 3 decades. The present authors analyzed the Journal of Cardiothoracic and Vascular Anesthesia (JCVA) at selected time intervals from 1990 to 2011 to quantify temporal variations in geographic publication patterns. The authors also determined whether previously described reductions in North American research productivity were accompanied by similar decreases in the number of other forms of publication in JCVA.
An observational study.
Internet analysis.
None.
The number of research articles, case reports and conferences, review articles, and letters in each issue of the journal were quantified in each of 4 time intervals consisting of consecutive 4-year periods (1990-1993, 1996-1999, 2002-2005, and 2008-2011). Forty-three countries published a total of 2,587 articles (ie, 1,141 research articles, 735 case reports, 175 review articles, and 536 letters) during the 4 time periods examined. Progressive decreases in the percentage of research articles, case reports, and letters, but not review articles, from North America were observed over time. Significant increases in the percentage of research articles and letters contributed by European authors in 2008 to 2011 were observed compared with 1990 to 1993. The percentage of all publications from the Middle East and Australasia increased significantly, whereas South America and Africa were relatively minor contributors to JCVA throughout the study period.
The present bibliometric analysis indicates that JCVA has changed from a journal that primarily published work from countries in North America and Europe to one in which the Middle East and Australasia now make a substantial number of contributions. These results suggest that JCVA has evolved into a truly international journal since its inception in 1987.
在过去的 30 年中，麻醉学文献的文献计量学发生了重大变化。本研究作者分析了《心胸血管麻醉杂志》（JCVA）从 1990 年到 2011 年的选定时间间隔，以量化地理出版模式的时间变化。作者还确定了北美研究生产力的先前描述的减少是否伴随着 JCVA 中其他形式的出版物数量的类似减少。
观察性研究。
互联网分析。
无。
在每个 4 年时间段（1990-1993 年、1996-1999 年、2002-2005 年和 2008-2011 年）中，定量了期刊每期的研究文章、病例报告和会议、评论文章和信件的数量。来自 43 个国家的作者总共发表了 2587 篇文章（即 1141 篇研究文章、735 篇病例报告、175 篇评论文章和 536 篇信件）。观察到研究文章、病例报告和信件的百分比从北美的百分比逐渐减少，但评论文章的百分比却有所增加。与 1990 年至 1993 年相比，2008 年至 2011 年欧洲作者的研究文章和信件百分比显着增加。中东和澳大拉西亚的所有出版物的百分比显着增加，而南美洲和非洲在整个研究期间对 JCVA 的贡献相对较小。
本文献计量学分析表明，JCVA 已从主要发表来自北美和欧洲国家的工作的期刊转变为中东和澳大拉西亚现在做出大量贡献的期刊。这些结果表明，自 1987 年成立以来，JCVA 已发展成为一本真正的国际期刊。
