This study reports hospitalization costs of fracture in Chinese patients aged over 45 years and evaluates their related factors in different fracture groups.
Purpose: To report hospitalization costs of treating fractures in Chinese patients aged over 45 years and to investigate the sociodemographic and health system factors related to variation in the costs.
Methods: Study participants were selected from the 2016 Health Accounts Database in Jiangsu in which patients' hospitalization costs were kept at various levels in hospitals. A multi-stage stratified sampling method was used to select study participants. Electronic medical records of patients aged 45 years and over with fractures were included. The International Classification of Diseases, Tenth Revision (ICD-10) was used to identify patients who were hospitalized due to fractures. A generalized linear model was used to estimate the extent to which a range of health system and sociodemographic factors were associated with the variation on hospitalization costs. Costs data were presented and analyzed using 2016 U.S. dollars.
Results: A total of 39,300 patients were included in the study. Vertebra, tibia/fibula, and hip were the most frequent fracture sites. The mean (median) of hospitalization cost of included fractures ranged from USD 3142 (USD 2420) for hand and wrist fractures to USD 10,355 (USD 9673) for hip fractures. Longer length of hospital stay, higher hospital level, and being covered by a health insurance were associated with higher hospitalization costs for all fracture types.
Conclusion: Our study reports hospital costs of the fracture using a large health accounts database in China and investigates the associated factors of hospital costs. Our results may inform cost-of-illness studies and economic evaluations of fracture preventions.
