  Abstract: Objective: To systematically sort out the research hotspots and progress in the field of the impact of DRGs payment model on medical service quality. Methods: Based on the Web of Science (WOS) Core Collection database, this study used the CitNetExplorer bibliometric software to conduct citation network analysis and visual mining of 206 relevant literatures published between 1986 and October 2025.Results: Research on the impact of the DRGs payment model on medical service quality has a long time span and has entered a period of rapid growth in recent years. Current research hotspots can be divided into four categories: (1) Research on the application of the DRGs payment model in medical quality evaluation; (2) Research on the actual impact of the DRGs payment model on medical service quality; (3) Research on the heterogeneous impact of the DRGs payment model on medical service quality; (4) Research on the impact mechanism and path of the DRGs payment model on medical service quality. In the future, it is necessary to attempt to construct a multi-dimensional analysis model, identify key contextual factors affecting policy effectiveness, and focus on core issues to deeply analyze complex causal mechanisms, so as to provide more solid theoretical support for the optimization of the DRGs payment model and the improvement of medical service quality.
