Abstract：Objective To understand the current status and hotspots of DRG research in China in order to provide reference for the focus and direction of subsequent research.Methods The literatures related to DRG were retrieved from China National Knowledge Network (CNKI). Descriptive analysis was made on the number of DRG literatures and the years of publication. Social network analysis was used to analyze the core authors, cooperative groups, high-frequency keywords and their relationships in DRG literatures.Results There were 2 602 journal articles with the theme of ‘DRG’ or ‘diagnosis related groups’. After 2015, the number of DRG literatures in China showed a multiple increase, with the annual literatures in 2021 and 2022 exceeding 500. There were 1 072 articles from core journals (41.20%) and 1 530 articles from non-core journals (58.80%). There were 188 core authors in the field of DRG research, mainly forming 7 cooperative groups led by Hu Mu and Guo Moning, with a total of 1 425 publications (54.77%). The network cograph and centrality analysis of high-frequency keywords showed that payment method, DRG prepaid, first page of medical records , hospital management, hospitalization cost and performance evaluation were the high-frequency keywords in the field of DRG research, and their point degree centrality and proximity centrality ranked first. However, the first page of medical records and CMI were more mediation-centered.Conclusion The number of literatures in the field of DRG research increases rapidly in recent years, but the quality of literatures needs to be evaluated and improved. The core authors are relatively concentrated and have strong overall influence and academic leading role. The research hotspot of DRG focuses on DRG payment and DRG performance evaluation and hospital management.
