Some incidents require early deployment of emergency department personnel not designated as disaster medical assistance team (DMAT). Although not as trained as DMAT members, they should be aware of basic disaster response concepts and knowledge. Educating disaster readiness to every healthcare staff in emergency departments would be ideal but it is very costly in both time and expense. To overcome this problem, we tried to evaluate the effectiveness of teaching basic concept and knowledge to non-designated personnel in a short-session and measure the effect.

This study is a before-and-after comparison study. From July 2020 to July 2022, a two-hour education was given to volunteers among doctors, nurses, paramedics and administrative staff working in emergency departments across four hospitals in Korea. Educational sessions consisted of basic disaster concept, pre-deployment DMAT preparations, initial actions required on incident site, key elements of incident response (command, control, safety, communication), and triage. Attendees were given a pretest before the session and another test after the session. Chi-square test and Wilcoxon rank test were used to compare the results.

Total of 105 volunteers participated in the study. Participants were mostly nurses (62.9%) followed by paramedics (23.8%). Overall knowledge level reported to be increased, including knowledge regarding DMAT deployment (29.5% to 93.3%, p<0.001), DMAT personnel (26.7% to 94.3%, p<0.001), DMAT-designated equipment (23.8% to 60.0%, p<0.001), initial response (27.6% to 69.5%, p<0.001) and patient transport priority (74.3% to 94.3%, p<0.001). Questions testing triage and rate of participants answering every question showed improvement with post-test median score of 67% and rate of 1.0% to post-test median score of 100% and rate of 35.2%, respectively (both p<0.001).

Educating non-DMAT personnel in emergency departments with a short session showed significant improvement in basic knowledge of disaster response. It may help institutions with limited resources.
