Diagnosis-related groups (DRGs) research in China is rapidly advancing, focusing on payment mechanisms and cost evaluation. However, implementation depth lags behind global standards, indicating a need for further development in DRG system research.
Area of Science:
- Health Economics
- Health Services Research
- Public Health Policy
Background:
- Diagnosis-related groups (DRGs) represent a significant shift in healthcare payment systems.
- Understanding the global and domestic research landscape of DRGs is crucial for policy development and implementation.
- This study provides a comprehensive review of DRG research status and evolutionary trends.
Purpose of the Study:
- To analyze the current research status of the DRGs payment system in China and globally.
- To identify topical issues and evolutionary trends in DRG research across different developmental stages.
- To compare the depth and focus of DRG research between China and other countries.
Main Methods:
- A systematic literature review was conducted using data from CNKI and Web of Science.
- Latent Dirichlet Allocation (LDA) topic modeling was employed to identify key research themes.
- Topic intensity and cosine similarity were used to analyze topic evolution and trends.
Main Results:
- Global DRG research emphasizes grouping optimization, implementation effects, and influencing factors.
- Chinese DRG research focuses on payment mechanisms, cost evaluation, quality control, and reform exploration.
- A total of 10,079 articles (6,758 English, 3,321 Chinese) were analyzed.
Conclusions:
- DRG research in China is experiencing rapid growth and increasing attention.
- Despite rapid development, the implementation depth of DRG research in China is less advanced compared to international research.
- Further research is needed to deepen the implementation and impact of DRG systems in China.
