High-fidelity low-cost modules for cellulitis and abscess

Introduction In the emergency departments, skin and soft tissue infections are highly common. Incision and drainage (I&D) are a critical procedural skill for emergency medicine trainees. Simulation-based training offers a practical and safe method for developing this skill. The objective was to assess the effectiveness of a newly developed, low-cost, ultrasound-compatible simulation model for abscess and cellulitis across four domains, including self-efficacy, fidelity, educational value and teaching quality, using the Michigan Standard Simulation Experience Scale (MiSSES). Methods A low-cost simulation model was developed using accessible materials such as Jell-O, psyllium husk, food colouring, povidone-iodine, and mayonnaise with maple syrup and used during structured training sessions. This model was employed in a prospective survey study among emergency medicine residents in Riyadh, Saudi Arabia. Participants completed the MiSSES, which assessed their self-efficacy, fidelity, educational value and teaching quality. Results A total of 107 residents participated. High average scores were reported in all domains: self-efficacy (mean 4.54 ± 0.52), fidelity (4.59 ± 0.49), educational value (4.60 ± 0.50) and teaching quality (4.64 ± 0.52). There were no significant differences by gender or previous experience. However, third-year residents reported lower self-efficacy than others (p = 0.012). Conclusions The newly developed simulation model was well received by learners and rated highly for educational effectiveness. Findings support its potential utility in resident training programmes, though further evaluation is needed to assess long-term outcomes and compare against other training methods.
