There has been a burgeoning interest for implementing bundled payments for hip fractures being treated with hemiarthroplasty, percutaneous pinning, and/or open reduction and internal fixation. Concerns exist about how hip fracture bundles may impede access to care for patients who require more resources, such as those with pathologic/neoplastic fractures.
The 2011 to 2017 American College of Surgeons—National Surgical Quality Improvement Program database was queried to identify patients undergoing percutaneous pinning, hemiarthroplasty, plate/screw, and intramedullary nail for hip fractures. Multivariate regression analyses were used to identify notable differences in 30-day complications, readmissions, reoperations, mortality, length of stay, and nonhome discharges between native and pathologic/neoplastic hip fractures.
A total of 67,548 patients were included—of which 378 (0.6%) had a pathologic/neoplastic hip fracture. Pathologic fractures (versus native hip fractures) had significantly higher odds of experiencing a prolonged length of stay >5 days (odds ratio [OR] 1.57), pulmonary embolism (OR 3.67), deep vein thrombosis (OR 2.03), 30-day readmissions (OR 1.43), and 30-day mortality (OR 2.66).
Patients sustaining a pathologic/neoplastic hip fracture have a worse adverse event profile. Risk adjustment based on facture etiology will be necessary to ensure that providers taking care of pathologic/neoplastic fractures are appropriately reimbursed to minimize barriers to access of care for this vulnerable cohort.
