In a mass casualty incident (MCI) exercise, live-actor patients (LAPs) simulated different scenarios in the exercise. This study compared the benefit to LAPs with that to exercise players (EPs) and nonparticipants (NPs). An MCI exercise was conducted in 2018. Emergency department (ED) nurses were assigned as EPs, LAPs, or NPs and asked to attend a pre-exercise lecture. A pre-exercise survey evaluated all ED nurses' background, confidence level, and knowledge of MCI management. Knowledge assessment included disaster medicine knowledge (DMK) and on emergency operation plan familiarity (EOPF). The same survey was conducted again after the exercise. A paired t-test was used to analyze the difference before and after the exercise in the 3 groups. Twenty-nine ED nurses completed both surveys. Confidence improved significantly for both the EP and LAP groups. The DMK of the LAP group improved significantly. EOPF also improved significantly for all 3 groups. A comparison of the improvement levels showed no significant difference between the EP and LAP groups for confidence, DMK, and EOPF. ED nurses can benefit from participating as LAPs in full-scale MCI exercises. Having ED nurses act as LAPs makes it possible to train more staff in 1 exercise.
