2000—2023年国际老年人共病研究文献计量学分析

A Bibliometric Analysis of the Global Research on Multimorbidity in Older Adults from 2000 to 2023

摘要

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日的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，并绘制高产国家/地区(发文量≥30篇)、机构(发文量≥43篇)的合作网络图及高频关键词(出现频次≥74次)的共现关系时间线图。采用CiteSpace 6.1.R6软件对作者、研究机构、国家等信息进行共现和聚类分析。采用R语言“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年以来全球发文量快速增长，美国在该领域的发文量(35.02%，907/2590)及总被引频次(31 343次)均最多。加拿大多伦多大学的发文量最大(2.59%，67/2590)，加拿大麦克马斯特大学的Jenny Ploeg(1.24%，32/2590)是成果产出最多的作者。BMC Geriatr(3.82%，99/2590)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”“older adults”“frailty”“aging”和“polypharmacy”。
结论近年来，老年人共病研究的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展开研究。

Abstract:
Objective To analyze the research trends and cutting-edge hot spots in the field of multimorbidity in older adults from 2000 to 2023 to provide reference for related research.
Methods We conducted a search in the Web of Science Core Collection database, specifically looking for articles or reviews in English on multimorbidity in older adults published between January 1, 2000 and October 24, 2023. VOSviewer 1.6.18 software was used to extract the contents in the literature and draw the cooperative network diagram of high-producing countries(≥30 articles) and institutions(≥43 articles) as well as the timeline diagram of high-frequency keywords(≥74 occurrences) co-occurrence relationship. CiteSpace 6.1.R6 software was used to co-occur and cluster analyze the information of authors, research institutions and countries. The "bibliometrix" package in R was used to analyze the evolution of keywords in the literature.
Results A total of 2590 documents consisting of 2230 Articles and 360 Reviews were obtained. The worldwide publication count significantly increased since 2000. Among the countries, the United States had the highest number of publications (35.02%, 907/2590) and total citations(31 343 times) in this field. The University of Toronto in Canada had the largest number of articles(2.59%, 67/2590). Jenny Ploeg of McMaster University was recognized as the most prolific author(1.24%, 32/2590). When it came to journals, BMC Geriatrics had the highest amount of literature related to multimorbidity(3.82%, 99/2590). The key areas of research in this field included multimorbidity, older adults, frailty, aging, and polypharmacy. Notably, there was 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 delve into primary health care, comprehensive geriatric assessment for older adults with multimorbidities, and maintenance of their overall quality of life.
