DRG Payment Records from a Chinese Tertiary Hospital, 2022-2024

Lixiang Wu's dataset comprises 251,811 Diagnosis-Related Group (DRG) payment records from a large tertiary hospital in an early-adopter region of China, covering 2022 to 2024. It was used to analyze the association between DRG payment reform and low-value inpatient admissions. The data includes the DRG Medical Expense Ratio (DER) as a key financial signal.

Use Cases

• Modeling the probability of low-value hospitalizations based on the DRG Medical Expense Ratio (DER).
• Analyzing temporal trends in low-value care incidence over a three-year period.
• Investigating the financial drivers behind 'check-up dominated' admissions within a DRG system.

Strengths

• Contains 251,811 payment records, providing a substantial sample size for analysis.
• Covers a three-year time span (2022-2024), allowing for longitudinal study of reform effects.
• Focuses on a specific, policy-relevant metric: the DRG Medical Expense Ratio (DER).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known, but the number of features or columns is unknown, limiting suitability assessment.
• Data is from a single hospital in one region, which may limit generalizability to other contexts.
