IntroductionSimulation is becoming the cornerstone for teaching clinical technical skills.1,2 Although a number of obstetric and gynecologic training models exist, none has been described in the literature for second-trimester surgical abortion or dilation and evacuation (D&E). Because complications associated with D&E have been directly related to provider skill level, 3 preclinical training with an appropriate model may improve patient safety, decrease trainer and trainee anxiety, and reduce the number of cases needed to achieve competency.Models can be expensive and may not be available in low-resource settings where the provision of safe abortion services can be life-saving. An easily and inexpensively produced model for use in low-and high-resource settings would be a valuable tool. One low-fidelity model that has been widely adopted for first-trimester uterine aspiration training is the papaya model, 4 which was shown to improve confidence and knowledge base during a medical student workshop.5 Other simple models exist in family medicine, emergency medicine, and urology. [6][7][8][9][10][11] No low-fidelity model has been formally described or evaluated in the literature for second-trimester D&E training. A D&E procedure differs significantly from uterine aspiration because it involves mechanical skills beyond sensing uterine texture and a greater understanding of the contours of the uterus and fetal parts.At the time of this study, 3 standard, low-fidelity D&E models existed. All have been used with trainees, yet the models have not been formally evaluated by experts in the field. We surveyed experienced D&E providers to assess how realistic these models were in simulating a D&E procedure.12 Our goal was to create an ideal composite model, with the most realistic components from each model.
