To examine the policy-driven evolution of death education for medical students in China, this study employed CiteSpace software to conduct a diachronic visual analysis of literature from the CNKI database between 2007 and 2024. By comparing research hotspots, collaborative networks, and keyword bursts before and after the implementation of the "Healthy China 2030" initiative (2007–2017 vs. 2017–2024), the study reveals a paradigm shift in medical humanities education under policy guidance. Findings indicate that post-2017, research focus shifted from theoretical themes like "view of life" and "attitudes toward death" to practice-oriented topics such as "ideological and political education in curricula" and "life attitudes." Changes in keyword centrality reflect a refinement of research subjects, while collaborative networks expanded from university-led efforts to include primary medical institutions. Burst keyword analysis further demonstrates a transition from generalized teaching models to deeper integration with specific courses. The study concludes that policy impetus has redirected research from theoretical exploration to practical application, reconstructing educational pathways through the modern transformation of traditional cultural resources. These findings provide empirical evidence for optimizing medical humanities education policies within the context of holistic health management across the life course.
