The number of abdominal hysterectomies (AH) performed by Obstetrics and Gynecology (OB/GYN) residents has decreased dramatically. Thus, there is a need for simulation training to compliment operating room experience. The objective of this study is to evaluate the impact of an AH simulator on resident surgeon confidence.


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 2015. The 1-hour simulation experience included a pre-test, a 5 minute presentation, the simulation, and a post-test. On the pre and post-tests, participants rated their confidence with the steps of AH as Not at All, Somewhat or Very confident.


Eighty-six percent (32/37) of possible residents completed the session with even representation from all levels of training (9 PGY-1, 7 PGY-2, 8 PGY-3 and 8 PGY-4). Knowledge of the steps of the procedure and instrumentation improved for all levels of trainees (P=.001). One hundred percent (16/16) of the PGY-1 and PGY-2 residents rated their confidence as increased afterwards, while only 25% (4/16) of the PGY-3 and PGY-4 residents did so. Ninety-four percent (30/32) rated the session as Very helpful on a scale of Not at All, Somewhat or Very Helpful.


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.
