Bibliometrics and Research Hotspots on Ventilator-Associated Pneumonia

呼吸机相关性肺炎(ventilator-associated pneumonia, VAP)是医院常见的获得性感染，是ICU内重症患者死亡的诱因之一。本研究旨在探讨过去已发表的文章，采用文献计量学方法和可视化分析来探索该领域的发展趋势和热点。方法：我们从SCI-Expanded of WoSCC中检索了过去十多年期间收录的关于呼吸机相关性肺炎所有文章，利用CiteSpace、bibliometrix和VOSviewer软件包分析文献计量数据。结果：共检索到1474篇文章，来自82个国家，其中“美国”以355篇文章位居第一，其次是中国(253篇)。“University of Barcelona”是最主要的学术机构，该研究主要发表在“Critical Care”等专业期刊上，“Torres A”以31篇已发表的出版物被评为最具生产力的作者。“mechanical ventilation”、“mortality”、“risk factors”、“acinetobacter baumannii”是最常见的关键词，“cefliderocol”、“COVID-19”“carbapenem-resistant acinetobacter baumannil”是近年来的研究热点。结论：通过本研究为全面理解呼吸机相关性肺炎提供了客观依据，不断开发、研究新的抗生素仍是当下重中之重，更好地完善治疗策略来改善临床结局。Ventilator-associated pneumonia (VAP) is a common acquired infection in hospitals and one of the causes of death in critically ill patients in the ICU. This study aims to explore the development trends and hotspots in this field by reviewing previously published articles using bibliometric methods and visual analysis. Methods: We retrieved all the articles on ventilator-associated pneumonia included in SCI-Expanded of WoSCC over the past decade, and analyzed the bibliometric data using the CiteSpace, bibliometrix, and VOSviewer software packages. Results: A total of 1474 articles were retrieved, coming from 82 countries. The United States ranked first with 355 articles, followed by China with 253. “University of Barcelona” is the most important academic institution. The research was mainly published in professional journals such as “Critical Care”. “Torres A” is the most productive author with 31 published papers. The most common keywords are “mechanical ventilation”, “mortality”, “risk factors”, and “Acinetobacter baumannii”. “Cefiderocol”, “COVID-19”, and “carbapenem-resistant Acinetobacter baumannii” have been research hotspots in recent years. Conclusion: This study provides an objective basis for a comprehensive understanding of ventilator-associated pneumonia, and the continuous development and research of new antibiotics remains a top priority. It is crucial to better refine treatment strategies to improve clinical outcomes.
