What defines a mass casualty incident in trauma management?

A mass casualty incident is defined by the overwhelming number of casualties that exceed the available resources to effectively manage the situation. This means that the standard protocols and resources of emergency response teams are insufficient to provide adequate care for all the injured individuals, necessitating a shift in the usual emergency response strategies. In this context, triage becomes critical as responders prioritize care based on the severity of injuries and the potential for survival.

While the number of injured individuals might be a contributing factor, it is not the sole determinant. For instance, having at least 10 injured individuals may lead to a mass casualty scenario, but if the resources are sufficient to handle them, it wouldn't be classified as a mass casualty event. Similarly, location or the requirement for only emergency medical response does not inherently define a mass casualty incident. It's the imbalance between casualties and resource availability that truly defines this type of situation in trauma management.
