RESUMEN
(1) Background: This study aims to understand the factors influencing hospitalization cost related to diabetes mellitus in two traditional Chinese medicine (TCM) hospitals, and to provide a scientific basis for TCM hospitals to control the hospitalization cost of chronic diseases, including diabetes mellitus. (2) Methods: Univariate analysis was used to preliminarily screen the factors related to hospitalization cost, and then multiple linear regression and path models were comprehensively used to analyze the influencing factors of hospitalization cost. (3) Results: The cost of hospitalization for diabetic patients was mainly affected by hospital level, length of stay, type of diabetes, and complications and comorbidities, and hospital level was the most critical influencing factor. (4) Conclusions: The higher the Chinese medicine hospital level, the longer the length of stay, and the more severe the complications and comorbidities, the higher the hospitalization cost for diabetic patients. The Chinese government should continue to promote the tiered medical treatment system and improve the standard of treatment at TCM hospitals to reduce the economic burden of chronic diseases, including diabetes mellitus.
