基于科学知识图谱的多病共存研究趋势与热点可视化分析

Visualized analysis on trend and hot spot of research on multimorbidity using knowledge map

目的:展示与分析多病共存的研究趋势和研究热点主题。方法:以“多病共存”“慢病共病”“慢性病共病”“multimorbidity”“multiple chronic conditions”等为检索词,检索中国知网、万方数据及Web of Science发表的多病共存相关的中英文文献,检索年限为建库至2022年7月,运用科学知识图谱软件VOSviewer从地区、中英文关键词、突现词等多个方面进行科学知识图谱共现网络分析,总结和比较国内外多病共存研究的现状和热点趋势。结果:共纳入251篇中文文献和6351篇英文文献。从研究趋势上看相关文献发表量总体呈波动上升趋势,但发展步伐不一;美国、英国、加拿大、中国、日本、澳大利亚等国家为代表的合作网络为最大的地区合作网络,德国、荷兰、美国、澳大利亚等为最早开展多病共存研究的地区。关键词聚类图谱结果显示,多病共存相关中文文献主要围绕多病共存诊疗与照护相关研究、多病共存研究常见疾病管理、多病共存研究方法3个主题聚类进行研究;英文文献主要以多病共存诊疗与照护相关研究、多病共存管理模式研究、共存疾病相关研究3个主题聚类为热点方向展开研究。突现词分析结果显示,多病共存近期研究热点主要为公共卫生(public health)、机器学习(machine learning)、老年医学(geriatric medicine)等。结论:国内外多病共存相关研究数量快速增加,我国在该领域研究相较于国外仍处在初级发展阶段。在研究热点上,多病共存研究主题从现象描述,逐步向多病共存医疗服务、研究方法等主题发展。

Objective To analyze the trend and hot spots of research on multimorbidity.Methods The Chinese and English literature in databases of CNKI,Wanfang data and Web of science from inception to July 2022 were retrieved using"multimorbidity"and"multiple chronic conditions"as the search terms.The scientific knowledge mapping software VOSviewer was used to analyze the co-occurrence network of scientific knowledge from the aspects of countries,Chinese and English keywords,burst terms and existing research results;and the status quo and hot trends of studies on multimorbidity at home and abroad were summarized and compared.Results A total of 251 Chinese publications and 6351 English publications were included.From the perspective of research trends,the overall trend of domestic and international publications showed a fluctuating upward trend in general,but the pace of development was different.The cooperation network represented by the United States,England,Canada,China,Japan,Australia and other countries was the largest regional cooperation network.Germany,the Netherlands,the United States,Australia and other countries were the first regions to carry out studies on multimorbidity.Studies on multimorbidity in China mainly focused on three topics:diagnosis,treatment and care of multimorbidity,common disease management of multimorbidity,and research methods of multimorbidity.The English literature mainly focused on the clustering of three topics:multi-disease co-diagnosis and care research,multi-disease co-management model research,and multimorbidity related research.The analysis of burst terms indicated the research focus and trend change in different time periods.The results of the outburst word analysis showed that the recent research hotspots of multimorbidity were public health,machine learning,geriatric medicine and so on.Conclusions The number of studies on the multimorbidity is rapidly increasing both domestically and internationally,and related research in China is still in the early stages of development.In terms of research hotspots,the research of multimorbidity has gradually shifted from phenomenon description to topics such as medical services and research methods of multimorbidity.
