As bundled reimbursement models continue to evolve, there is a continued effort to increase the value of care for patients undergoing arthroplasty. The authors sought to evaluate the effect of surgeon specialization (arthroplasty vs non-arthroplasty) on acute outcomes for patients with hip fracture who underwent total hip arthroplasty (THA), in an effort to determine whether the value of care can be improved by surgeons specializing in these procedures. They performed a multicenter retrospective cohort study of patients who had hip fracture and were treated with THA between June 2013 and February 2018 at 2 academic institutions that were involved in bundled reimbursement initiatives. Patients were stratified based on the subspecialty training of the operative surgeon (fellowship-trained adult reconstruction vs other orthopedic sub-specialty), and 90-day readmissions, length of stay, and discharge disposition were compared between groups. A total of 291 patients were included in the final cohort, with 120 (41.2%) undergoing surgery performed by a fellowship-trained adult reconstruction surgeon. No significant difference was found in age, sex, race, or American Society of Anesthesiologists score between the 2 groups. In addition, no significant difference was found in length of stay, discharge to a facility, or 90-day readmissions on univariable or multivariable analysis when adjusted for age, sex, body mass index, and American Society of Anesthesiologists score. This study showed that the acute outcomes used to assess the value of care for patients undergoing THA were not significantly different when the surgery was performed by an adult reconstruction specialist compared with other orthopedic surgeons at 2 high-volume academic centers with perioperative care pathways. Alternative modalities to significantly improve acute postoperative outcomes in a bundled reimbursement model must be investigated. [Orthopedics. 2020;43(5):e442-e446.].
