Key Points

This research aims to analyze factors influencing the orthopedic discharge patients' disease groups based on admission routes using KDRG.
Analyzed orthopedic discharge patients from Hospital A from January 1 to December 31, 2023, based on claims to the Health Insurance Review and Assessment Service.
Used variables including general characteristics, admission characteristics, MDC characteristics, and severity characteristics.
Performed chi-square tests, independent sample t-tests, decision tree analysis, and ROC curve AUC assessment.
The highest disease group ratio occurred in the case with a length of stay longer than 7 days, admission via the emergency room, and age 85 years or older, with a percentage of 89.7%.
The ROC curve AUC value was 0.800, indicating good predictive model performance.

Implication

Analyzes factors affecting DRG A in orthopedic patients, suggesting improved resource management.
