A Novel Abdominal Hysterectomy Simulator and Its Impact on Obstetrics and Gynecology Residents' Surgical Confidence

INTRODUCTION: The number of abdominal hysterectomies (AHs) performed by OB/GYN residents has decreased dramatically. Thus, there is a need for simulation training to complement operating room experience. METHODS: A low-fidelity AH simulator was constructed from craft-store supplies costing less than $40. OB/GYN residents in a single academic program completed the simulation between July and September of 2015. The 1-hour simulation experience included a pretest, a 5-minute presentation, the simulation, and a posttest. On the pre- and posttests, participants rated their confidence with the steps of AH as not at all, somewhat, or very confident. RESULTS: Eighty-six percent (32 of 37) of possible residents completed the session, with even representation from all levels of training (nine PGY 1, seven PGY 2, eight PGY 3, and eight 8 PGY 4 residents). Knowledge of the steps of the procedure and instrumentation improved for all levels of trainees (p < .001). One hundred percent (16 out of 16) of the PGY 1 and PGY 2 residents rated their confidence as increased afterwards, while only 25% (four out of 16) of the PGY 3 and PGY 4 residents did so. Ninety-four percent (30 out of 32) rated the session as very helpful on a scale of not at all, somewhat, or very helpful. DISCUSSION: A low-fidelity, low-cost simulator showed an increase in trainee confidence with AH, particularly in the first- and second-year trainees. Nearly all participants found the exercise helpful, suggesting that it may be beneficial to incorporate into OB/GYN training programs nationwide.
