Abstract:

Objective　To offer novel insights for both domestic and international research endeavors examining the present research status, trends, and focal points pertaining to postoperative delirium (POD) by bibliometric analysis. Methods　On July 10, 2023, the Web of Science (WoS) core database was searched to identify the literatures on POD published between 2002 and 2022. The various aspects, including annual publication volume, citation frequency, country of publication, affiliated institutions, journals, authors, keywords, and direction, were examined. The CiteSpace software was applied to provide the visual representation of the overall characteristics. Results  This study included 1 208 publications. The analysis showed that the annual publication volume of literatures related to POD increased from 2002 to 2022; the United States is the country with the most publications, followed by China; Inouye Sharon and Marcantonio Edward R emerged as the two most prolific contributors in term of publication volume; Harvard University emerged as the institution with the highest number of publications; the elderly, long-term hospitalization, cancer, pain, hip fractures, cardiac surgery, abdominal surgery, and patients in intensive care were of particular interest in POD researches. Establishment of predictive model for POD, management model of preventive system, patients' long-term outcomes, etc. had high attention. Conclusions  Researches on POD are steadily expanding, but there is disparity between China and developed nations. The focal point of future research endeavors should be the implementation of systematic and standardized approaches to assess, prevent, and treat POD.
