Purpose: Toquantify the costof resident involvement in academic sports medicine by examining differences inoperative time, relative value units (RVUs) per case, and RVUs per hour between attending-only cases and cases with resident involvement. Methods: A retrospective analysis of common sports medicine procedures identified by Current Procedural Terminology code was performed using data from the American College of Surgeons National Surgical Quality Improvement Program database from 2006 to 2015. Matched cohorts were generated based on demographic variables, comorbidities, preoperative laboratory values, and surgical procedures. Bivariate analysis examined mean differences in operative time, RVUs per case, and RVUs per hour between attending-only cases and cases with resident involvement. A cost analysis was performed to quantify differences in RVUs generated per hour in terms of dollars per case. Results: A total of 14,840 attending-only cases and 2,230 resident-involved cases were used to generate 2 matched cohorts (N = 4,460). Resident cases had greater mean operative times than attending-only cases, with operative time increasing as residents became more senior (P <.01). Residents participated in cases with larger mean RVUs per case (P <.01). Cases with lone attendings showed greater RVUs per hour (P <.01). The cost of resident involvement increased nearly 8-fold from postgraduate year 1 to postgraduate year 6 residents ($25.70 vs $200.07). Conclusions: In academic sports medicine, the involvement of resident physicians increases operative time. The associated decrease in attending physician efficiency inRVUs per hour equates to an average cost per case of $159.18, with costs increasing as residents become more senior.
