A low-cost high-fidelity model for abscess simulation

Abstract

Background: Treatment of a subcutaneous abscess is a commonly encountered scenario across multiple specialties. Prior simulation models for abscess incision and drainage have been limited by their cost and reproducibility.

Methods: We developed a realistic abscess model with commonly available materials that can be utilized in fresh cadaver labs at a cost of less than $1 USD per use. The model was evaluated for content validity with pre- and post-measures by 25 pre-clinical medical students.

Results: The model described herein successfully simulates commonly encountered subcutaneous abscesses. Pre and post-training surveys demonstrated a significant increase in all outcomes measures.

Conclusions: The model presented in this manuscript can be easily incorporated into training programs that utilize a fresh cadaver lab for multi-procedural resident training. It provides a realistic abscess that can be placed in almost any anatomical location at a fraction of the cost, and significantly reduced preparation time compared to previously described models.
