Summary
A novel, low-fidelity simulation model for second-trimester dilation and evacuation (D&E) procedures demonstrates realistic tactile feedback. This cost-effective training tool, made from accessible materials, is highly favored by physicians for improving patient safety and provider competency.
Area of Science:
- Medical Simulation
- Surgical Training
- Gynecologic Procedures
Background:
- Simulation training enhances patient safety and reduces training case requirements.
- Dilation and Evacuation (D&E) complications correlate with provider skill.
- No validated low-fidelity D&E training models exist for second-trimester procedures.
Purpose of the Study:
- To assess physician perceptions of 3 D&E simulation models.
- To establish a composite training model based on realism.
- To evaluate the potential utility of D&E simulation models in medical education.
Main Methods:
- Experienced obstetrics-gynecology and family medicine physicians were surveyed.
- Three distinct D&E models were evaluated at national conferences.
- Model components were rated using a Likert scale for realism.
Main Results:
- 80% of participants favored one model for training over two others.
- The preferred model featured components like fetal parts (82% realism) and placenta (60% realism).
- Respondents found the preferred model to have tactile similarities to the D&E procedure.
Conclusions:
- A D&E simulation model constructed from a plastic bottle with fabric components is a promising training tool.
- This low-fidelity model offers tactile realism for D&E training.
- Further development and testing are recommended for this cost-effective simulation model.
