Chemical exposures can cause direct and indirect injuries to responding medical personnel. Therefore, hospital healthcare providers should be provided with disaster response training that includes identification of chemical hazards, establishment of the hazard zone, personal protective equipment use, decontamination, and chemical injury antidote use. This study evaluates the educational effectiveness of the chemical-mass casualty incident response education module (C-MCIREM) for hospital healthcare providers.

This was a retrospective quasi-experimental study. Subjects were hospital providers who enrolled in the C-MCIREM program between May 1, 2021, and July 26, 2022. Subjects were hospital providers from Bucheon, Mokpo, Iksan, Jeonju, and Dae-gu cities in South Korea. Subjects completed pre, post, and three-month knowledge retention and self-assessments of readiness tests, as well as evaluations on tabletop exercises (TTX), and a satisfaction survey (11-point Likert) after the course. The instructors scored teamwork measures via standardized evaluations on TTX throughout the course. The K-paired Sample Friedman test was used to compare samples.

127 respondents were enrolled. The median knowledge score rose from 51/100 (39, 66) to 85.5/100 (73.75, 90) with a median retention score of 74/100 (64, 88) (p<0.001). Participants felt their readiness to respond increased in all facets (all p<0.001) on the post and retention test for the MCI situation. All three hospital teams showed significant increases in teamwork between the median of the 1st and 4th TTX as 27/100 (23.5, 29) and 69/100 (66.75, 69.5) (p<0.05). Participants were overall satisfied (9.1/10 SD 1.13) and would recommend the training to others (9.15/10 SD 1.2).

C-MCIREM participants had high satisfaction with a significant increase and persistence in knowledge, improved teamwork, and self-assessed readiness to respond to a chemical mass casualty incident.
