The authors performed a bibliometric analysis of 3,458 medical school educational environment (MSLE) publications from the Web of Science, Scopus, and PubMed databases from 2000 to 2025. They used the Bibliometrix R package to visualize networks, analyze publication trends, top countries, institutions, journals, authors, and keywords. MSLE research has steadily expanded over the past two decades with contributions from various global regions. Significant keywords relate to curriculum, medical education, medical students, learning environment, and perception. New topics include program evaluation, digital pedagogy, student well-being, online learning, and simulation. Thematic mapping revealed central domains such as professionalism and program evaluation. The study emphasizes the need for long-term multi-institutional studies, international cooperation and the involvement of underrepresented regions.
