Red flags

  • The mass casualty incident changes the standard of care from the individual to the population — the greatest good for the greatest number
  • The START triage categorises in under 60 seconds per patient: the immediate, the delayed, the minimal and the expectant
  • The first patient to walk into the ED is often the least injured — the most injured arrive later by ambulance
  • The incident commander does not treat patients — the commander coordinates
  • The chemical, biological or radiological incident requires the decontamination before the entry to the ED

The disaster and the mass casualty incident (the MCI) is the event in which the number or the type of casualties exceeds the normal capacity of the emergency medical services, and it requires the shift from the individual standard of care to the population standard — the greatest good for the greatest number. The Fellowship candidate must know the disaster cycle, the START triage, the incident command system, the surge capacity, and the decontamination, because the MCI is the ultimate test of the emergency physician's ability to manage the system, not just the patient.[1]

The disaster cycle

The disaster management is a cycle of four phases. Prevention: the mitigation of the hazard (the building codes, fire safety, public health). Preparedness: the planning, training, stockpiling, drills, mutual aid agreements. Response: the activation, triage, treatment, transport, incident command. Recovery: the return to the normal, psychological support, debrief, review and the improvement. The emergency physician is involved primarily in the response, but the preparedness (the drills and the plans) determines the quality of the response.[1]
