- Abstract
Introduction: Compared with hemiarthroplasty (HA), reverse total shoulder arthroplasty (RTSA) may provide greater cost and health-related benefits for patients with complex three- and four-part proximal humeral fractures. This study set out to compare RTSA versus HA for the incremental cost per incremental improvement in quality adjusted life years (QALYs) for a hypothetical cohort of patients with proximal humerus fractures., Methods: Parameters and characteristics for a hypothetical cohort of elderly patients with proximal humerus fractures were collected through the literature. A cohort-level Markov decision model was constructed. Incremental cost-effectiveness ratios representing the difference in cost divided by the difference in QALYs were calculated, and scenario, one-way, and probabilistic analysis were conducted., Results: RTSA was associated with lower cost and greater effectiveness compared with HA. The predicted cost difference corresponded to a saving of $99,626 per 100 individuals treated, and the predicted difference in QALY was 16.8 per 100 individuals treated. Results were sensitive to the discount rate, the health-related quality of life assigned to health states, and the cost of the surgical procedures. In probabilistic analysis, 77.1% of iterations were cost-effective at a threshold willingness-to-pay for a QALY of $100,000 US dollars., Discussion: Findings suggest that RTSA may be a cost-effective alternative to HA for treating elderly patients requiring surgery for proximal humerus fractures., Data Availability: The model and corresponding code are available on request to the corresponding author., Level of Evidence Using the Journal of the American Academy of Orthopedic Surgeons Guidance: Level III., (Copyright © 2021 by the American Academy of Orthopaedic Surgeons.)
