Abstract

Introduction: Cutaneous abscess incision and drainage and foreign body removal are 2 common procedures in a variety of outpatient settings. The goal of this project was to create a novel, clean, reusable task trainer that could more accurately reproduce all the steps necessary to perform cutaneous abscess drainage or foreign body removal including ultrasound to identify the abscess cavity or foreign body.

Methods: The novel task trainer was constructed using silicone for both the base and the top skin. Toothpaste mixed with saline was used for the abscess material as this produced an ultrasound image that mimicked purulent material. A piece of a metal paper clip was imbedded in the top skin to mimic a cutaneous foreign body. Physician assistant (PA) students given a didactic lecture then used the novel task trainer as part of a clinical skills course.

Results: After the activity, the PA students were asked to voluntarily complete a brief preretrospective/postretrospective survey comprised 8 questions that addressed their self-perceived knowledge and skills using a 5-point Likert scale. Survey data from an initial cohort of PA students at one university show effectiveness of the models when used with the associated curriculum.

Discussion: This study demonstrates the feasibility of constructing a practical, low-cost, non-animal-based task trainer for the purpose of training incision and drainage of cutaneous abscesses and removal of cutaneous foreign bodies. This novel task trainer allows for ultrasound skill development and provides realistic imaging experience.
