Comparing Training Techniques in Chemical Disaster Preparedness

Abstract

Introduction:

Currently, there are no universally accepted personal protective equipment (PPE) training guidelines for Emergency Medicine physicians, though many hospitals offer training through a brief didactic presentation. Physicians’ response to hazmat events requires PPE utilization to ensure the safety of victims, facilities, and providers; providing effective and accessible training is crucial. In the event of a real disaster, time constraints may not allow a brief in-person presentation and an accessible video training may be the only resource available.

Aim:

To assess the effectiveness of video versus in-person training of 20 Emergency Medicine Residents in Level C PPE donning and doffing (chemical-resistant coverall, butyl gloves, boots, and an air-purifying respirator).

Methods:

A prospective observational study was performed with 20 Emergency Medicine residents as part of Emergency Preparedness training. Residents were divided into two groups, with Group A viewing a demonstration video developed by the emergency preparedness team, and Group B receiving in-person training by a Hazmat Team Member. Evaluators assessed critical tasks of donning and doffing PPE utilizing a prepared evaluation tool. At the drill’s conclusion, all participants completed a self-evaluation to determine their confidence in their respective trainings.

Results:

Both video and in-person training modalities showed significant improvement in participants’ confidence in doffing and donning a PPE suit (p>0.05). However, no statistically significant difference was seen between training modalities in the performance of donning or doffing (p>0.05).

Discussion:

Video and in-person training are equally effective in preparing residents for donning and doffing Level C PPE, with similar error rates in both modalities. Future trainings should focus on decreasing the overall rate of breaches across all training modalities.
