Abstract
Background: Bibliometrics allows for the evaluation of the editorial performance and thematic organization of health journals with an institutional function.
Objective: To analyze the scientific output of the IMSS Medical Journal, indexed in PubMed (2005-2025), to describe its temporal evolution and publication patterns (productivity, typology, authorship, citations, and topics).
Materials and methods: A descriptive and longitudinal bibliometric study was conducted using records retrieved from PubMed. Indicator processing was performed using Anne O' Tate; thematic analysis was based on the co-occurrence of keywords and MeSH terms, with clustering and visualization in VOSviewer.
Results: A total of 2,661 articles were identified. Annual output showed variations, with a peak in 2023 (205), followed by 2024 (171) and 2025 (107). Observational clinical-epidemiological designs predominated. Authorship was primarily collaborative (average: 4.1; median: 4), with a concentration in teams of 3-6 authors. Production was centralized in Mexico, particularly in Mexico City (1276). 47.65% of articles received ≥ 1 citation (iCite), with an estimated 3,592 citations and 1.35 citations per article.
Conclusions: The journal exhibits a predominantly national, territorially centralized, and methodologically observational profile, with concentrated citations and a broad thematic agenda. These findings provide evidence to guide thematic priorities and actions to strengthen editorial quality and visibility.
[文献计量学分析]. PubMed中revsta m dica del IMSS的科学产出（2005-2025）。
背景：文献计量学允许对具有机构功能的卫生期刊的编辑表现和专题组织进行评估。目的：分析PubMed检索的IMSS医学期刊（2005-2025）的科学产出，描述其时间演变和出版模式（生产力、类型学、作者、引文和主题）。材料和方法：使用PubMed检索的记录进行描述性和纵向文献计量学研究。使用Anne O' Tate进行指标处理；主题分析基于关键词和MeSH术语的共现，并在VOSviewer中进行聚类和可视化。结果：共鉴定2661篇文献。年产量变化较大，2023年（205）达到峰值，2024年（171）和2025年（107）达到峰值。观察性临床流行病学设计占主导地位。作者身份主要是合作的（平均：4.1；中位数：4），集中在3-6个作者的团队中。生产集中在墨西哥，特别是墨西哥城（1276年）。47.65%的文章被引用次数≥1次（iCite），估计被引用3592次，每篇文章被引用1.35次。结论：该期刊展示了一个主要的国家、地区集中和方法观察概况，具有集中的引用和广泛的主题议程。这些调查结果为指导专题优先事项和加强编辑质量和知名度的行动提供了证据。
