RESUMEN
INTRODUCTION: Appropriate faculty supervision and conditional independence of residents during training are required for autonomous and independent postgraduate practice. However, there is a growing concern that competence for transition to independent practice is not universally met. We hypothesize that surgery residents play a significant and active role in achieving their own independent status. METHODS: Over seven academic years (July 2014 through June 2021), 46 surgeons supervised and intraoperatively assessed the performance of 51 residents using validated Objective Structured Assessment of Technical Skill (OSATS) and Zwisch Operative Autonomy (ROA) assessments. Resident readiness to perform procedures independently (RRI) was graded as yes, no, or not applicable. Data were analyzed using descriptive statistics with categorical variables reported as frequencies and percentages. RESULTS: A total of 1657 elective procedures were performed by residents supervised by faculty. Association between RRI and postgraduate year (PGY), OSATS scores, ROA, resident and faculty gender, and case complexity was analyzed. Results indicated positive correlation between RRI and summative OSATS score (r = 0.510, P < 0.001), PGY (r = 0.535, P < 0.001) and ROA (r = 0.473, P < 0.001). Percentage of overall RRI increased from 7% at PGY1 to 87.4% at PGY5. Meaningful autonomy ratings increased from 23.6% at PGY1 to 92.5% at PGY5. Variations in ratings was observed when considering case category and complexity. CONCLUSIONS: RRI increases with years of training with variation when considering the specialty/The Accreditation Council for Graduate Medical Education procedure category and the complexity of cases. Specialty fellowships are a viable option to address the gap in The Accreditation Council for Graduate Medical Education categories when residency alone cannot reach appropriate independence. Residents' technical skills play a crucial role in evaluating RRI and granting operative autonomy.
