A 2018 poll by the American College of Emergency Physicians shows 93% of surveyed doctors believe their emergency department is not fully prepared for patient surge capacity in the event of a natural or man-made disaster. While an emergency disaster plan is activated during any incident where resources are overwhelmed, many US emergency physicians today think of a mass casualty incident (MCI) as the inciting event. To better prepare our communities, an MCI simulation took place in Chicago 2018 with participation from local and federal representatives. Included were Chicago fire, police, and emergency medical services agencies, emergency medicine physicians, resident participants, and medical student volunteer victims.

The study’s aim was to determine whether resource intensive moulage was an expected component or a beneficial adjunct, if moulage-based training would improve physician preparedness, and if such a training would increase the likelihood of future involvement in local disaster preparations. Analysis was performed on pre- and post-training surveys completed by participants. By reviewing the benefits versus cost, future MCI simulation planners can efficiently use their funds to achieve training goals.

Thirty-two emergency medicine physicians were surveyed before and after a five-hour training session on October 20, 2018, which included 89 moulage victims. Twenty-four after-event surveys were completed. All completed surveys were utilized in data analysis.

Of polled participants, a 68% improvement in general preparedness was achieved. While only 19% of participants cited current involvement in their facility’s disaster planning in pre-event survey, the likelihood of involvement after training was 8.2/10. Overall, the importance of moulage an essential component to such trainings remained constant.

Moulage is an expected and crucial element to MCI training and should be incorporated as extensively as resources allow. MCI trainings improve physician preparedness and potentially increase physician involvement in disaster planning at home institutions.
