Bibliometric Analysis of Studies on Postoperative Delirium: A Web of Science Database Example

Abstract

Aim: Postoperative delirium is a complication that occurs acutely after surgical procedures, especially in elderly patients. The aim of this study is to scientifically analyze the publications on postoperative delirium. Method: For the purpose of the research, articles on postoperative delirium published in the Web of Science (WoS) Core database were analyzed using scientific mapping methodology. The articles were scanned in the “postoperative delirium” word group in the WoS database, and the obtained data were analyzed with the VOSViewer 1.6.19 program. Results: It was seen that the most used keywords related to postoperative delirium have been delirium (n=1131), postoperative delirium (n=444), elderly (n=209), cardiac surgery (n=199), hip fracture (n=184). On the subject of postoperative delirium, Edward R Marcantonio was the author with the most publications with 83 articles, and Harvard Medical School was determined as the institution with the most publications with 142 publications. Conclusion: The number of publications on postoperative delirium has increased especially in the last ten years. While this situation shows the importance of postoperative delirium in anesthesia studies, it is important that researchers who have published in recent years on postoperative delirium have been from different countries.
