Postoperative delirium (POD) is one of the most frequent complications after surgery which is closely associated with many adverse outcomes, including high mortality and low quality of life. This study aims to carry out a bibliometric analysis of POD and its risk factors from 2012 to 2022 to reveal the research status and hot spots.
This study is a bibliometric and visualized analysis.
Relevant publications between 2012 and 2022 were extracted from the Web of Science Core Collection database. CiteSpace software (v6.1. R2, Drexel University), VOSviewer software (v1.6.18, Leiden University), and the Online Analysis Platform of Literature Metrology were used to analyze research attributes. These publications were used to analyze research attributes, including countries, journals, institutions, authors, keywords, and burst detection, to predict trends and hot spots.
We included a total of 1,324 related documents from 2012 to 2022. The literature on POD has increased significantly since 2016. The United States and Harvard University were the leading literature publishing country (436/1324, 32.9%) and institution (112/1324, 8.5%). Anesthesia and Analgesia was the most frequently published journal. Keywords analysis with VOSviewer revealed that the keywords could be divided into five clusters, including anesthesia techniques, cardiac surgery, risk factors, intraoperative anesthesia monitoring, and postoperative cognitive dysfunction. We included a total of 198 POD risk factors documents, and the literature on POD risk factors increased. The People's Republic of China and Harvard University were the leading literature publishing country (53/198, 26.8%) and institution (12/198, 6.1%). Elderly, hip surgery, frailty, postoperative pain, cardiac surgery, dementia, and depression are keywords that are risk factors for POD.
The number of literature on POD in the field of anesthesia has increased significantly. Risk factors and anesthesia techniques are still key areas of research. Encephalogram, the use of sedatives, and perioperative nursing may be the new research focus. Older adults, hip fractures, cardiac surgery, liver transplants, dementia, and depression are hot words in the field of POD risk factors.
术后谵妄（POD）是手术后最常见的并发症之一，与许多不良后果密切相关，包括高死亡率和低生活质量。本研究旨在对2012年至2022年期间POD及其危险因素进行文献计量分析，以揭示研究现状和热点。
本研究为文献计量与可视化分析。
从Web of Science核心合集数据库中提取2012年至2022年期间的相关出版物。使用CiteSpace软件（v6.1.R2，德雷塞尔大学）、VOSviewer软件（v1.6.18，莱顿大学）和文献计量在线分析平台对研究属性进行分析。这些出版物用于分析研究属性，包括国家、期刊、机构、作者、关键词和突发检测，以预测趋势和热点。
我们共纳入了2012年至2022年期间的1324篇相关文献。自2016年以来，关于POD的文献显著增加。美国和哈佛大学是主要的文献发表国家（436/1324，32.9%）和机构（112/1324，8.5%）。《麻醉与镇痛》是发表频率最高的期刊。使用VOSviewer进行关键词分析表明，关键词可分为五个聚类，包括麻醉技术、心脏手术、危险因素、术中麻醉监测和术后认知功能障碍。我们共纳入了198篇关于POD危险因素的文献，且关于POD危险因素的文献有所增加。中华人民共和国和哈佛大学是主要的文献发表国家（53/198，26.8%）和机构（12/198，6.1%）。老年人、髋关节手术、虚弱、术后疼痛、心脏手术、痴呆和抑郁是POD危险因素的关键词。
麻醉领域关于POD的文献数量显著增加。危险因素和麻醉技术仍是关键研究领域。脑电图、镇静剂的使用和围手术期护理可能是新的研究重点。老年人、髋部骨折、心脏手术、肝移植、痴呆和抑郁是POD危险因素领域的热门词汇。
