High Incidence of Hemiarthroplasty for Shoulder Osteoarthritis Among Recently Graduated Orthopaedic Surgeons

BACKGROUND: Primary glenohumeral osteoarthritis is a common indication for shoulder arthroplasty. Historically, both total shoulder arthroplasty (TSA) and hemi-shoulder arthroplasty (HSA) have been used to treat primary glenohumeral osteoarthritis. The choice between procedures is a topic of debate, with HSA proponents arguing that it is less invasive, faster, less expensive, and technically less demanding, with quality of life outcomes equivalent to those of TSA. More recent evidence suggests TSA is superior in terms of pain relief, function, ROM, strength, and patient satisfaction. We therefore investigated the practice of recently graduated orthopaedic surgeons pertaining to the surgical treatment of this disease. QUESTIONS/PURPOSES: We hypothesized that (1) recently graduated, board eligible, orthopaedic surgeons with fellowship training in shoulder surgery are more likely to perform TSA than surgeons without this training; (2) younger patients are more likely to receive HSA than TSA; (3) patient sex affects the choice of surgery; (4) US geographic region affects practice patterns; and (5) complication rates for HSA and TSA are not different. METHODS: We queried the American Board of Orthopaedic Surgery's database to identify practice patterns of orthopaedic surgeons taking their board examination. We identified 771 patients with primary glenohumeral osteoarthritis treated with TSA or HSA from 2006 to 2011. The rates of TSA and HSA were compared based on the treating surgeon's fellowship training, patient age and sex, US geographic region, and reported surgical complications. RESULTS: Surgeons with fellowship training in shoulder surgery were more likely (86% versus 72%; OR 2.32; 95% CI, 1.56-3.45, p<0.001) than surgeons without this training to perform TSA rather than HSA. The mean age for patients receiving HSA was not different from that for patients receiving TSA (66 versus 68, years, p=0.057). Men were more likely to receive HSA than TSA when compared to women (RR 1.54; 95% CI, 1.19-2.00, p=0.0012). The proportions of TSA and HSA were similar regardless of US geographic region (Midwest HSA 21%, TSA 79%; Northeast HSA 25%, TSA 75%; Northwest HSA 16%, TSA 84%; South HSA 27%, TSA 73%; Southeast HSA 24%, TSA 76%; Southwest HSA 23%, TSA 77%; overall p=0.708). The overall complication rates were not different with the numbers available: 8.4% (15/179) for HSA and 8.1% (48/592) for TSA (p=0.7555). CONCLUSIONS: The findings of this study are at odds with the recommendations in the current clinical practice guidelines for the treatment of glenohumeral osteoarthritis published by the American Academy of Orthopaedic Surgeons. These guidelines favor using TSA over HSA in the treatment of shoulder arthritis. Further investigation is needed to clarify if these practice patterns are isolated to recently graduated board eligible orthopaedic surgeons or if the use of HSA continues with orthopaedic surgeons applying for recertification.

Use of the Behavior Assessment Tool in 18 Pilot Residency Programs

Background: The purpose of this study was to determine the feasibility and evaluate the effectiveness of the American Board of Orthopaedic Surgery Behavior Tool (ABOSBT) for measuring professionalism. Methods: Through collaboration between the American Board of Orthopaedic Surgery and American Orthopaedic Association\u27s Council of Residency Directors, 18 residency programs piloted the use of the ABOSBT. Residents requested assessments from faculty at the end of their clinical rotations, and a 360° request was performed near the end of the academic year. Program Directors (PDs) rated individual resident professionalism (based on historical observation) at the outset of the study, for comparison to the ABOSBT results. Results: Nine thousand eight hundred ninety-two evaluations were completed using the ABOSBT for 449 different residents by 1,012 evaluators. 97.6% of all evaluations were scored level 4 or 5 (high levels of professional behavior) across all of the 5 domains. In total, 2.4% of all evaluations scored level 3 or below reflecting poorer performance. Of 431 residents, the ABOSBT identified 26 of 32 residents who were low performers (2 or more \u3c level 3 scores in a domain) and who also scored below expectations by the PD at the start of the pilot project (81% sensitivity and 57% specificity), including 13 of these residents scoring poorly in all 5 domains. Evaluators found the ABOSBT was easy to use (96%) and that it was an effective tool to assess resident professional behavior (81%). Conclusions: The ABOSBT was able to identify 2.4% low score evaluations ( Level of Evidence: Level II

Operative Experience During Orthopaedic Residency Compared with Early Practice in the U.S.

BACKGROUND: The goal of surgical education is to prepare the trainee for independent practice; however, the relevance of the current residency experience to practice remains uncertain. The purpose of this study was to identify the surgical procedures most frequently performed in orthopaedic residency and in early surgical practice and to identify surgical procedures performed more often or less often in orthopaedic residency compared with early surgical practice. METHODS: This retrospective cohort study included American Medical Association (AMA) Current Procedural Terminology (CPT) codes (n = 4,329,561 procedures) reported by all U.S. orthopaedic surgery residents completing residency between 2010 and 2012 (n = 1,978) and AMA CPT codes for all procedures (n = 413,370) reported by U.S. orthopaedic surgeons who took the American Board of Orthopaedic Surgery Part II certifying examination between 2013 and 2015 (n = 2,205). Relative rates were determined for AMA CPT codes and AMA CPT code categories for adult and pediatric surgeries that had frequencies of ≥0.1% for both practitioners and residents. RESULTS: The top 25 adult AMA CPT code categories contributed 82.1% of the total case volume for residents and 82.4% for practitioners. Knee and shoulder arthroscopy were the most frequently performed procedures in adults in both residency and early practice. Humerus/elbow fracture and/or dislocation procedures and other musculoskeletal-introduction or removal procedures were the most frequently performed procedures in pediatric cases in both residency and early practice. Of the total 78 adult and 82 pediatric code categories included in our analysis that had a frequency of \u3e1% in residency or early practice, there were 4 adult and 6 pediatric code categories demonstrating 44% to 1,164% greater frequency in residency than in early practice, and there were 8 adult and 7 pediatric code categories demonstrating 26% to 73% less frequency in residency than in early practice. CONCLUSIONS: Similarity between residency and early practice experience is generally strong. However, we identified several AMA CPT code categories and individual CPT codes for which the level of exposure during residency varied substantially from early practice experience. These findings can help residencies ensure adequate trainee exposure to procedures performed commonly in early practice
