Does orthopaedic resident efficiency improve with respect to decreased fluoroscopic times in tibial intramedullary nailing? A measure of an ACGME milestone

Abstract

Background: Intramedullary nailing of tibial fractures is a surgical milestone from the Accreditation Council for Graduate Medical Education (ACGME). Our purpose was to evaluate if fluoroscopic time decreased with increasing resident experience and could be used as a measure of this milestone. Methods: Current Procedural Terminology (CPT) codes were used to identify patients who underwent intramedullary nailing of tibial shaft fractures under the direction of fellowship-trained trauma attending staff. The data collected included patient demographics, fracture classification, fluoroscopic imaging total time, and the post-graduate years (PGY) of orthopaedic residency of the operating resident. Exclusions of patients included concomitant fluoroscopic procedures, inadequate records, or surgeries involving primary assisting residents with less than PGY-2 experience. We compared overall groups between half years and looked at individual resident years for each of the continuous variables. Results: When residents were grouped as senior (PGY-4 and PGY-5) or junior (PGY-2 and PGY-3), seniors used significantly less fluoroscopy than juniors (207.39 sec vs. 258.30 sec, P=0.018). In the first half of the academic year, PGY-2 residents completed tibial nailing slowest in terms of fluoroscopic usage (P=0.003). PGY-4 residents completed tibial nailing faster in terms of fluoroscopic usage than other years (P=0.031). In the second half of the academic year, PGY-5 residents used significantly less fluoroscopy than PGY-2 residents (P=0.035). Conclusions: As the ACGME currently has no measurement for resident progress and efficiency regarding tibial shaft intramedullary nailing, our data indicate that fluoroscopic measurements may be useful in assessing resident proficiency.
