Melanoma trainer using simulated back skin: an innovative design.

Area of Science:

• Dermatology
• Medical Education
• Biomedical Engineering

Background:

• Developing effective training tools is crucial for medical education.
• Accurate identification of cutaneous pigmented lesions, including melanoma, requires specialized training.
• Simulated models offer a consistent and accessible method for practicing diagnostic skills.

Purpose of the Study:

• To present the creation and validation of a novel melanoma trainer using simulated back skin.
• To evaluate the reliability and fidelity of the simulated melanoma trainer for educational purposes.
• To provide medical students with a tool to practice differentiating benign and malignant pigmented lesions.

Main Methods:

• Melanoma trainers were constructed from flexible polyurethane foam and pigmented silicone rubber.
• Non-Hispanic and Hispanic white skin tones were simulated.
• Board-certified dermatologists and dermatology residents assessed the models' accuracy and reliability.

Main Results:

• The simulated skin models accurately represented normal nevi and clinically suspicious lesions, including melanomas.
• High inter-rater reliability was observed for identifying suspicious lesions (κ = 0.64) and melanomas (κ = 0.97).
• Excellent reliability was achieved in selecting melanomas for biopsy (κ = 0.96).

Conclusions:

• The simulated back skin melanoma trainer is a reliable and durable educational tool.
• The trainer allows for frequent use and provides exposure to a diverse range of pigmented lesions.
• This model enhances medical students' ability to diagnose cutaneous pigmented lesions effectively.
