Evaluating medical service performance of hospitals in Sichuan Province, China: exploratory factor analysis and hierarchical clustering analysis based on diagnosis-related groups

Significant regional and hierarchical disparities in medical service performance were observed across Sichuan Province, with Chengdu region demonstrating optimal performance. For TGHs, hospitals in the "Inferior" cluster are recommended to enhance their medical ability and efficiency compared to those in the "Excellent" cluster. Conversely, hospitals in the "Excellent" cluster should focus on controlling medical costs compared to those in the "Inferior" cluster. For SGHs, hospitals in the "Inferior" cluster should concentrate on improving medical security and ensuring patient safety compared to those in the "Middle" and "Excellent" clusters.
