Summary
A low-cost gelatin breast model effectively trains medical students in ultrasound-guided breast biopsy. This simulation significantly boosts confidence and knowledge, offering an accessible training solution, especially for resource-limited settings.
Area of Science:
- Medical Education
- Surgical Simulation
- Biomedical Engineering
Background:
- An interdisciplinary team developed a low-cost gelatin breast model for ultrasound-guided breast biopsy training.
- The model utilizes readily available materials, costing approximately $4.40 USD per unit.
Purpose of the Study:
- To assess the efficacy of a novel, low-cost gelatin breast model in teaching ultrasound-guided breast biopsy.
- To evaluate the first-time user experience and perceptions of medical students using the simulation model.
Main Methods:
- A gelatin-based breast model was created using medical-grade gelatin, Jell-O™, water, olives, and surgical gloves.
- Thirty medical students participated in simulation-based training during their surgical clerkship.
- Pre- and post-training surveys assessed learner confidence, knowledge, and model perception.
Main Results:
- Confidence in performing ultrasound-guided breast biopsies under minimal supervision increased from 4% to 75%.
- All participants reported increased knowledge, and 71% found the model anatomically accurate and suitable for training.
- The study achieved a 93.3% survey response rate.
Conclusions:
- The low-cost gelatin breast model is effective in enhancing student confidence and knowledge for ultrasound-guided breast biopsies.
- This simulation provides a cost-effective and accessible training method, particularly beneficial for low- and middle-income countries.
