Innovative, Reproducible Simulation Model for Teaching Abdominal Hysterectomy
Purpose: Evaluate the impact of abdominal hysterectomy (TAH)
simulation model and curriculum on resident confidence, knowledge, and ability.
Background: Work hour restrictions, treatment advances and
increased utilization of minimally invasive surgery has led to completion of
fewer TAHs by Ob/Gyn residents. Simulation-based training can augment operative
Methods: At the start of their oncology rotation, residents
participated in a new TAH curriculum. Curriculum included instruction on
surgical instruments and performing a TAH using a low-fidelity, reproducible
simulation model. Pre-, post-, and end-of-rotation surveys were completed
evaluating confidence, knowledge, satisfaction, and educational impact.
Results: Production of TAH simulation models for 1 year of
curriculum required 2.5 hours of time at a cost of $3.25 per model. In the
first 6 months, 100% of residents (n=12) felt that the simulation was “very” or
“extremely effective” and 73% reported the overall quality of the simulation
was “excellent.” Overall confidence improved with mean composite confidence
scores of 12.25, 14.55, and 15.9, pre-sim, post-sim, and end-of-rotation
respectively (p=0.0451). Experienced residents ( >5 prior hysterectomies)
had higher confidence scores than inexperienced residents; however,
improvements in confidence were not impacted by level of experience (p=0.3442).
The majority of residents reported a high educational impact of the simulation,
with 91% of residents reporting a score of 4 or 5 (5-point Likert scale) for
the simulation’s impact on knowledge and visualization of the surgical steps.
Discussions: This low cost, reproducible TAH simulation curriculum
can be an effective adjunct in surgical education to improve residents’
confidence and knowledge in performing abdominal hysterectomies.
