Influence of Procedure Volumes and Adherence to Process of Care “Quality” Measures on Patient Outcomes in Total Joint Arthroplasty (TJA)

The relationship between surgeon and hospital procedure volumes and clinical outcomes in total joint replacement (TJR) has become the focus of payer-driven proposals to regionalize care. At the same time, many national policy initiatives are focusing on improving quality by encouraging adherence to evidence-based processes of care. The purpose of this study was to evaluate the independent contributions of surgeon procedure volume, hospital procedure volume, and standardization of care on short-term postoperative outcomes and resource utilization in lower TJR.
