AIM
Although the number of global studies on ECMO, which is an important support system in the treatment of COVID-19 related respiratory failure, has increased in recent months, there is still no bibliometric study on the use of ECMO in COVID-19 in the literature. The aim of this study is to analyze the scientific articles on the use of ECMO in COVID-19 by statistical and bibliometric methods.
METHOD
Articles published between 2019-2022 about the use of ECMO in COVID-19 were obtained from the Web of Science (WoS) database and analyzed using statistical and bibliometric methods. Spearman correlation coefficient was used for correlation studies. Network visualization maps were used to identify effe analysis and trending topics.
RESULTS
A total of 1197 publications were found. 758 (63.3%) of these publications were articles. The top 3 contributing countries to the literature were USA (257, 33.9%), Germany (102, 13.4%) and Japan (87, 11.5%). The top 3 most active institutions were League of European Research Universities (90), Harvard University (50), and Udice French Research Universities (39). The top 3 journals with the highest count of publications were ASAIO Journal ( = 36), Frontiers in Medicine (22), and Perfusion-UK ( = 20). According to the average count of citations per article, the most influential journals were JAMA (1319), Intensive Care Medicine (327), and Lancet (95.7), respectively. We have shared a summary of 758 articles in this comprehensive bibliometric study on the use of ECMO in COVID-19.
CONCLUSION
It can be said that the use of ECMO in COVID-19 has been the trending topic recently and most of the studies are from countries in the ELSO Awards of Excellence list which indicates that the follow-up of ECMO in certain centers and teams can also be influencing the publications. This article can be a useful resource for clinicians, scientists, and students concerning global output for ECMO use in COVID-19.
目的
尽管近几个月来，关于 ECMO（COVID-19 相关呼吸衰竭治疗中重要的支持系统）的全球研究数量有所增加，但文献中仍没有关于 ECMO 在 COVID-19 中应用的文献计量学研究。本研究旨在通过统计和文献计量学方法分析 COVID-19 中使用 ECMO 的科学文献。
方法
从 Web of Science (WoS) 数据库中获取 2019 年至 2022 年期间发表的关于 COVID-19 中使用 ECMO 的文章，并使用统计和文献计量学方法进行分析。使用 Spearman 相关系数进行相关性研究。网络可视化地图用于识别分析和趋势主题。
结果
共发现 1197 篇出版物。其中，758 篇（63.3%）为文章。文献贡献最多的前 3 个国家是美国（257 篇，33.9%）、德国（102 篇，13.4%）和日本（87 篇，11.5%）。最活跃的前 3 个机构是欧洲研究型大学联盟（90 个）、哈佛大学（50 个）和法国 Udice 研究型大学（39 个）。发表文章数量最多的前 3 个期刊是 ASAIO 杂志（=36）、医学前沿（22）和英国灌注（=20）。根据每篇文章的平均引用次数，最有影响力的期刊分别是 JAMA（1319）、重症医学（327）和柳叶刀（95.7）。在这项关于 COVID-19 中 ECMO 使用的全面文献计量学研究中，我们分享了 758 篇文章的摘要。
结论
可以说，COVID-19 中 ECMO 的使用一直是最近的热门话题，而且大多数研究来自 ELSO 卓越奖名单中的国家，这表明某些中心和团队对 ECMO 的随访也会影响出版物。本文可为临床医生、科学家和学生提供有关 COVID-19 中 ECMO 使用的全球研究成果的有用资源。
