Abstract
Thailand is an aging society. An increasing incidence of hip fracture is a financial burden. This study aimed to evaluate the factors affecting to hospital reimbursement among geriatric hip fracture patients in Surat Thani Hospital. Our study analyzed hospital reimbursement using data from the Thailand Health Security Office. All patients aged >50 years admitted to Surat Thani Hospital were included in the study. A linear regression model was used to analyze factors affecting to hospital reimbursement with eight determinant factors: age, sex, length of stay, ICD10 principal diagnosis group, discharge status, number of comorbidities, number of procedures, and year of admission. All statistical analyses and graphical displays were performed using the R program, version 3.1.3. It revealed that 1,575 hip fracture patients were treated from October 2009–September 2016. 94.5% were females. About 38.9% of them were 80-89 years. Factors affecting to hospital reimbursement among geriatric hip fracture patients were as follows; sex, age, ICD10 principal diagnosis group, discharge status, number of comorbidities, number of procedures, and year of admission (p <0.001) and the predictive accuracy was 78.2%. The predictor of a number of procedures was the highest adjusted R square at 32.3% and length of stay at 71.3%.
