Abstract

Total shoulder arthroplasty (TSA) has proved a cost-effective, reproducible procedure for multiple shoulder pathologies. As utilization of TSA continues to grow, it is important to investigate procedure diversity, training, and other characteristics of surgeons performing TSA. To identify surgeons performing TSA in the Medicare population, the Medicare Provider Utilization and Payment Databases from 2012 through 2014 were used. This dataset includes any provider who bills Medicare >10 times with a single billing code. A web-based search was performed for each physician performing >10 TSA in all years of the study to identify their surgical training characteristics. Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year (71,973 TSA). Only 44.3% (609/1374) of surgeons met this threshold for all 3 years (55,538 TSA). Of these 609 surgeons, 191 (31.3%) were shoulder and elbow fellowship trained (21,444 TSA). Shoulder and elbow fellowship-trained surgeons were at earlier points in their careers and practiced in large referral-based centers with other surgeons performing TSA. In addition to TSA, surgeons performed other non-arthroplasty shoulder procedures (80.2% of surgeons), total knee arthroplasty (46.3%), repairs of traumatic injuries (29.8%), total hip arthroplasty (27.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%) during the study period. With less than one-third of TSA performed by shoulder and elbow fellowship-trained surgeons with consistent moderate-volume practices, the impact of consistent high-volume practices and targeted fellowship training on quality must be determined.
