What criteria determine evacuation priority in a deployed setting?

• A. Proximity to evacuation routes
• B. Time since injury
• C. Life-threatening conditions, need for advanced care, stability, mission risk, and evacuation feasibility
• D. Patient age

Answer: (C)

In deployed settings, evacuation priority is driven by clinical urgency combined with what the mission and transport capabilities allow. The most appropriate criteria bring together the severity of the condition (life-threatening issues that need rapid higher-level care), whether the patient truly needs to be moved to access that care (need for advanced care), whether the patient can safely tolerate transport (stability for transport), how evacuating them affects the mission (mission risk), and whether evacuation is actually feasible given the current resources and conditions (evacuation feasibility). This combination ensures those in the direst medical need are moved promptly to the right care while considering the practical realities of operating in a combat or remote environment.

For example, a patient with airway obstruction or uncontrolled bleeding is prioritized because both the condition is life-threatening and higher-level care is required, and if transport is possible without compromising care. Conversely, a stable injury that can be managed on site, or a patient for whom evacuation would expose the unit to unacceptable risk or is not currently feasible, would not take priority over those in genuine need of emergent care.

Proximity to evacuation routes, time since injury, or patient age alone do not determine priority. Proximity might influence feasibility, time since injury can inform urgency in some contexts but isn’t the primary driver, and age isn’t the main factor in determining who should be evacuated first.
