INTRODUCTION:
Multiple victim incidents (MVIs) stress emergency systems, necessitating swift and coordinated action. In 2023, a bus fell off a viaduct from a height of approximately 8 meters, causing 36 victims. This incident complicated response efforts due to the unique challenges MVIs pose in resource allocation and care.
OBJECTIVES:
To profile the victims regarding initial triage and injuries and evaluate hospital allocation based on the required care level.
MATERIAL & METHODS:
A retrospective, observational study was conducted analyzing the data from the bus incident. Information on each victim"s START classification, primary injury, transport mode, and destination was recorded. Some data points were missing due to the victim count.
RESULTS:
Using START, 33 victims were labeled "green" (91.6%) and 3 "yellow" (8.3%). No victims were "red" or "gray". 89% of victims, including all "yellow" ones, were transported by basic units. One transport mode wasn"t noted. Post-incident, 69% went to an Emergency Care Unit with an ER and X-ray. 8.3% were sent to regional hospital with general surgery and CT capabilities, while 16.6% were directed to trauma center with specialists. Two victims' destinations (5%) weren't recorded. Most injuries were facial traumas and TBIs, aligning with the event's dynamics: passengers thrust forward inside the bus.
CONCLUSION:
Despite the traumatic mechanism of the accident, over 90% of victims were triaged as "green." Analyzing accident kinematics is crucial to identify injury types, aiding initial evaluation and resource management. The transportation of "yellow" victims by basic ambulances hints at triage issues or resource misutilization. Yet, all victims were initially directed to suitable facilities based on on-site evaluations, even if later transfers were required.
