Title : Predictors and cost-effectiveness of 1-year postoperative mortality and readmission of hip fracture in the elderly: A comparison of different treatments
Abstract:
Hip fractures, especially femoral neck fractures (FNF), are common and have high mortality rates within a year, causing significant financial and social costs. We conducted a retrospective cohort study using competing risk analysis on FNF patients aged 60 or above who underwent primary hemiarthroplasty or internal fixation. The internal fixation group had significantly lower 1-year mortality rates (10.46%) than the arthroplasty group (11.08%), with higher mortality hazard ratios in men, increasing age, and Charlson Comorbidity Index (CCI). Surgical complication incidence was 11.13% and 7.57%, with a higher hazard ratio in the internal fixation group and with increasing CCI and in men. Medical complication rates at 90-day were 6.33% and 7.04%. The arthroplasty group spent over 197,677.82 USD in medical costs, leading to a reduction of 1 person-year in survival time and a higher incremental cost-effectiveness ratio.
