Abstract


OBJECTIVE
The aim of this study was to evaluate the characteristics of the emergency medical services (EMS) response and clinical information on mass casualty chemical incidents in Korea.
METHODS
This retrospective observational study analyzed the integrated data of the EMS rescue records and EMS-treated severe trauma registry from January 2012 to December 2013. Two databases were integrated using the unique accident identification number. Chemical incidents were defined by an in-depth review of the EMS rescue records according to a previous study. Mass casualty incidents were defined as more than 6 injured individuals. The rescue, EMS, and hospital variables of mass casualty chemical incidents were analyzed.
RESULTS
A total of 8 mass casualty chemical incidents and 73 patients were included. The mean responded rescue vehicles and EMS vehicles were 2.4 and 3.5, respectively. The 4 incidents were an oil spill due to traffic accidents and most patients suffered minor trauma. A carbon monoxide leak caused the largest number of patients (23 people). The explosion caused by flammable polyethylene leaks showed the highest severity. In that explosion, the mortality rate was 40% and 8 patients had a disability at discharge.
CONCLUSION
This study evaluated the characteristics of the EMS response and clinical information on mass casualty chemical incidents in Korea.
