The Association Between Hospital Length of Stay and 90-Day Readmission Risk for Femoral Neck Fracture Patients: Within a Total Joint Arthroplasty Bundled Payment Initiative

摘要

Background: Hip arthroplasty is increasingly performed as a treatment for femoral neck fractures (FNFs). However, these cases have higher complication rates than elective total hip arthroplasties (THAs). The Center for Medicare and Medicaid Services has created the Comprehensive Care for Joint Replacement model to increase the value of patient care. This model risk stratifies FNF patients in an attempt to appropriately allocate resources, but the formula has not been disclosed. The goal of this study was to ascertain if patients with FNFs have different readmission rates compared to patients undergoing elective THA so that the resource utilization can be assessed.
