Purpose: To characterize the number and type of cases staffed by PGY-6 residents in the OBL setting in an academic IR practice.

Materials and Methods: Cases performed in the OBL setting for the 2023-2024 academic year and staffed by a PGY-6 resident were tallied. Cases were then categorized based on case type.

Results: Three PGY-6 residents were included in this analysis, one integrated IR/DR resident and two independent IR residents. Each PGY-6 resident was assigned to the OBL on average 80 days for the 2023-2024 academic year, during which they staffed a total of 1572 cases (avg 524 cases/resident). Most common cases staffed by PGY-6 residents in the OBL setting included venous access interventions (448 cases) and ultrasound guided biopsies (434 cases). Additionally, PGY-6 residents staffed more advanced complex procedures in the OBL setting including 109 interventional oncology procedures (TARE, TACE, immuno-embolization) and 65 non-oncologic embolization procedures (UFE, PAE, GAE, HAE, pelvic congestions and varicocele embolization). Furthermore, PGY-6 residents staffed 50 superficial venous interventions, which are primarily performed in the OBL setting in our practice.

Conclusion: This study demonstrates the large number and heterogenous case-mix encountered by PGY-6 residents at our institution during the 2023-2024 academic year. Given the increasing interest in and demand for performing outpatient IR cases in the OBL setting, we believe the large number and heterogenous case-mix, including both basic and complex cases, staffed by PGY-6 residents at our institution well equips them for the ever-evolving IR practice patterns. This cross-sectional study is limited by its evaluation of a single academic year and only PGY-6 residents. Further studies will aim to characterize the longitudinal experience of integrated IR/DR residents across their training in the OBL setting.
