Core Tip

Core Tip: This retrospective study investigated the composition and factors of the hospitalization costs of fall-related injuries in elderly inpatients and established a factor-based, cost-related group. The total hospitalization costs were 180479203.03 RMB. The quantile regression (QR) results showed that patient age, gender, length of hospital stay, payment method, wound position, wound type, operation times and operation type significantly influenced the inpatient cost (P < 0.05). The cost grouping model was established based on the QR results, and the cost of each combination varied significantly. Our grouping model of hospitalization costs clearly reflects the key factors affecting hospitalization costs.
