[Scientific output of the Revista Médica del IMSS in PubMed (2005-2025): a bibliometric analysis].

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.
