目的 通过文献计量学分析术后谵妄的研究现状、趋势和热点，为国内外研究提供新思路。方法 检索Web of Science核心数据库中2002-2022年发表的术后谵妄相关文献(检索日期为2023年7月10日)，对年度发表量、引用频率、发文国家、机构、期刊、作者、关键词、研究方向等方面进行分析，并运用CiteSpace软件对文献的总体特征性进行可视化分析。结果 共纳入1 208篇文献，2002-2022年术后谵妄相关文献年发表量呈上升趋势;美国是发文最多的国家，其次是中国;发文量前两位作者是Inouye Sharon和Marcantonio Edward R;发文最多的机构是哈佛大学;老年、长期住院、癌症、疼痛、髋关节骨折、心脏手术、腹部大手术和重症监护患者是术后谵妄研究的热点群体。术后谵妄预测模型的建立、预防性系统管理模型、患者远期结局等方面都具有较高的关注度。结论 术后谵妄的研究正逐步增加，但是我国和发达国家仍存在一定差距。针对术后谵妄的系统规范性评估、预防、治疗是未来重点关注的研究方向。
Bibliometrics analysis of current status of researches on postoperative delirium based on Web of Science database
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.
