Multimorbidity is frequently seen in primary care. We aimed to identify and analyze publications on multimorbidity, including those that most influenced this field.
A bibliometric analysis of publications from 2005 to 2019 in the PubMed database containing "multimorbidity" or "multi-morbidity" identified with the tool iCite. We analyzed the number of publications, total citations, the article-level metric Relative Citation Ratio (RCR), type of study, and journals with the most cited articles.
The number of publications using "multimorbidity" has continuously increased since 2005 (2005-2009: 138; 2010-2014: 823; 2015-2019: 3068). The median number of total citations per article was 3. The median RCR was 1.04. Articles with RCR at or above the 97th percentile (RCR = 7.43) were analyzed in detail (n = 104). In 34 publications of this subgroup (33%), the word multimorbidity was used but was not the subject of study. The remaining top 70 publications included 32 observational studies, 22 reviews, five guideline statements, three analysis papers, two randomized trials, three qualitative studies, two measurement development reports, and one conceptual framework development report. The publications were produced by authors from 32 countries. They were published in 37 different journals, ranging from one to four articles in the same journal.
We found a continuous increase in the number of publications about multimorbidity since 2005. However, our study suggests that the numbers should be considered only a general trend because multimorbidity was not the main subject in 33% of publications in a subgroup of 104 analyzed in detail.
多重疾病在初级保健中很常见。我们旨在识别和分析关于多重疾病的出版物，包括那些对该领域影响最大的出版物。
使用iCite工具对2005年至2019年PubMed数据库中包含“多重疾病”或“多种合并症”的出版物进行文献计量分析。我们分析了出版物数量、总被引次数、文章层面指标相对引用率（RCR）、研究类型以及被引次数最多的文章所在期刊。
自2005年以来，使用“多重疾病”的出版物数量持续增加（2005 - 2009年：138篇；2010 - 2014年：823篇；2015 - 2019年：3068篇）。每篇文章的总被引次数中位数为3次。RCR中位数为1.04。对RCR处于或高于第97百分位数（RCR = 7.43）的文章进行了详细分析（n = 104）。在该亚组的34篇出版物（33%）中，使用了“多重疾病”一词，但它并非研究主题。其余排名前70的出版物包括32项观察性研究、22篇综述、5篇指南声明、3篇分析论文、2项随机试验、3项定性研究、2项测量开发报告和1项概念框架开发报告。这些出版物由来自32个国家的作者撰写。它们发表在37种不同的期刊上，同一期刊发表的文章数量从1篇到4篇不等。
我们发现自2005年以来关于多重疾病的出版物数量持续增加。然而，我们的研究表明，这些数字仅应被视为一种总体趋势，因为在详细分析的104篇亚组出版物中，有33%的出版物中多重疾病并非主要研究主题。
