Abstract: To understand the interdisciplinary development trends in biomedical research across representative countries globally, this study focuses on the research outcomes of grants from exemplary funding institutions. Utilizing bibliometric indicators to measure the degree of interdisciplinary collaboration, a social network of disciplines is constructed to identify key and crucial supporting disciplines. The study reveals that from 2018 to 2022, the degree of interdisciplinary collaboration in biomedical research has gradually increased in the United States, Japan, the United Kingdom, Australia, European Union countries, and China. The number and scope of involved disciplines have expanded, though the intensity of the supporting role varies significantly among different disciplines. The increasing prominence of computer science including information technology, coupled with the ongoing crucial role of mathematics, particularly represented by statistics, along with the emergence of new materials, technologies, and equipment in the field of chemistry, collectively provide vital support for biomedical research. There are differences in the emphasis and supporting disciplines involved in research across different countries. Future planning of biomedical research grants and talent cultivation should pay more attention to the synergy of interdisciplinary knowledge and the integration of knowledge beyond the biomedical scope. To better support the innovation and development of the biomedical research paradigm, further exploration on deep collaboration models among researchers from different disciplines, interdisciplinary discipline setting in biomedical field, interdisciplinary training models for talent at different education stages, the arrangement of non-medical general supporting discipline courses, and scientifically optimize the content of medical teaching materials should be conducted.
