A Bibliometric Analysis of the Global Research on Multimorbidity in Older Adults From 2000 to 2023
-
摘要: 目的 分析2000—2023年老年人共病领域的国际研究趋势及前沿热点,以期为老年人共病研究提供借鉴。 方法 检索Web of Science数据库,将文献类型限制为“ Article”或“ Review”,纳入发表时间为2000年1月1日—2023年10月24日老年人共病相关英文文献。采用VOSviewer 1.6.18软件对文献中的内容进行提取,并绘制国家(地区)、机构的合作网络图及关键词共现关系时间线图。采用CiteSpace 6.1.R6软件对作者、研究机构、国家(地区)等信息进行共现和聚类分析。采用R语言的“bibliometrix”包分析文献的关键词演变趋势。 结果 共获得老年人共病相关文献2590篇(包括Article 2230篇、Review 360篇)。自2000年来全球发文量快速增长,美国在该领域的发文量(907篇,35.02%)及总被引频次(31343次)均最多。加拿大多伦多大学(67篇,2.59%)的发文量最大,加拿大麦克马斯特大学的Jenny Ploeg(32篇,1.24%)是成果产出最多的作者。BMC Geriatr(99篇,3.82%)是收录老年人共病相关文献最多的期刊。该领域高频关键词主要为multimorbidity、olderadults、frailty、aging和polypharmacy。 结论 近年来,老年人共病的研究热点主要集中于老年人共病与衰老的关系,以及与共病相关的衰弱和多重用药方面。未来可更多围绕老年综合评估、初级卫生保健以及生活质量等内容进行研究。Abstract: Objective This study aims to analyze the research trends and cutting-edge hot spots in the field of multimorbidity in older adults from 2000 to 2023. Methods We conducted a search in the Web of Science Core Collection database, specifically looking for articles or reviews in English literature on multimorbidity in older adults published between January 1, 2000, and October 24, 2023. VOSviewer 1.6.18 software was used to extract the content in the literature and to draw the cooperative network diagram of countries(regions) and institutions and the timeline diagram of keyword co-occurrence relationship. CiteSpace 6.1.R6 software was used to co-occur and cluster analyse the information of authors, research institutions and countries(regions). The "bibliometrix" package in R was used to analyse the evolution of keywords in the literature. Results A total of 2590 documents were obtained, consisting of 2230 Articles and 360 Reviews. The worldwide publication count has significantly increased since 2000. Among the countries(regions), the United States has the highest number of publications (907 articles, accounting for 35.02% of the total) and total citations (31,343 times) in this field. In terms of institutions, the University of Toronto stands out with 67 articles (2.59%) as the top contributor. McMaster University's author, Jenny Ploeg is recognized as the most prolific authors, having published 32 articles (1.24%). When it comes to journals, BMC Geriatrics has the highest amount of literature related to multimorbidity (99 articles). The key areas of research in this field include multimorbidity, older adults, frailty, aging, and polypharmacy. Notably, there is growing interest in studying the relationship between multimorbidity and aging in older adults, as well as the impact of frailty and polypharmacy on multimorbidities. Conclusions In recent years, research on multimorbidities in the elderly has primarily centered around examining the correlation between comorbidities and aging, as well as exploring the impact of frailty and polypharmacy on individuals with multimorbidities. Future research could potentially delve into the significance of primary health care and comprehensive geriatric assessment in effectively managing comorbidities among older adults, while also emphasizing the importance of maintaining their overall quality of life.
