【摘要】 目的:利用CiteSpace软件对国内外老年人多重慢病的研究热点及其变化进行可视化分析。方法:检索2000-2020年中国知网、万方、维普数据库及PubMed和Web of Science数据库中老年人多重慢病相关的研究文献，筛选并提取文献信息，应用CiteSpace软件对纳入的文献进行关键词共现、突现分析。结果:共筛选出中文文献349篇，发文量整体呈现波动上升趋势；共筛选出英文文献761篇，发文量呈现平缓上升趋势。英文文献在临床医学领域、流行性病学领域、卫生管理领域中出现频次前两位的关键词均为多重用药(强度为6.42)及衰弱(强度为6.73),近年来对住院(强度为1.35)、生活质量(强度为1.19)和抑郁(强度为0.94)的关注度提升。而中文文献在以上3个领域最高频的关键词分别为多重用药(频次为17)、影响因素(频次为47)、生活质量和社区护理(频次均为4),文献多集中于研究综合评估(强度为0.97)、疾病管理(强度为1.13)和医养结合(强度为0.53)。结论:相比于英文文献关注老年人的复合健康问题，提出建立以人群为导向，与多重慢病相适应的整合型诊疗模式，中文文献仍侧重于从单一疾病视角出发进行研究。因此国内有必要基于跨学科交叉交流环境，在政策的合理引导下拓展老年人健康问题认识视角和研究现状，建立更适应多重慢病老年人健康需求的服务模式。更多还原

【Abstract】 Objective: To conduct a visualization analysis on the research hotspots and changes of multimorbidity of the elderly at home and abroad using the CiteSpace software.Methods: The research literature related to multimorbidity of the elderly from 2000 to 2020 was searched in databases including CNKI, Wanfang, Weipu, PubMed and Web of Science, and literature information was screened and extracted. CiteSpace was used to present the keywords co-occurrence and burst detection of the included literature. Results: The Chinese literature was screened with 349 articles, and the overall number of articles showed a fluctuating increase trend. The English literature was screened with 761 articles, and the number of articles showed a steady upward trend. The top two high-frequency keywords in English literature in the fields of clinical medicine, epidemiology and health management were polypharmacy(intensity 6.42) and frailty(intensity 6.73). The focus on hospitalization(intensity 1.35), quality of life(intensity 1.19) and depression(intensity 0.94) had increased in recent years. The most frequent keywords in Chinese literature in the above three fields were multiple polypharmacy(frequency 17), influencing factors(frequency 47), and quality of life and community care(both frequency 4). The literature mostly focused on comprehensive assessment(intensity 0.97), disease management(intensity 1.13) and health care integration(intensity 0.53). Conclusion: Compared with the English literature, which concentrates more on the complex health problems of the elderly and proposes to establish an integrated treatment model compatible with multimorbidity, the Chinese literature still focuses on research from a single disease perspective. Therefore, it is necessary to expand the understanding perspective and research status of elderly health problems based on the interdisciplinary cross-communication environment and under the reasonable guidance of policies in China, and to establish a service model that is more adapted to the health demands of the elderly with multimorbidity.更多还原
