Guidelines for Triage in Mass Casualty Situations?

April 5, 2026

Quick Answer

In mass casualty situations, triage is the process of quickly assessing and prioritizing patients for treatment based on the severity of their injuries. The goal is to provide the best possible care with limited resources. The triage process is often divided into four categories: immediate, delayed, walking, and expectant.

Triage Categories

In a mass casualty situation, the triage process is crucial for allocating limited medical resources effectively. The four primary categories for triage are immediate, delayed, walking, and expectant. Immediate care is provided to patients with life-threatening injuries that require immediate attention, such as severe bleeding or penetrating trauma. These patients are typically treated first.

Triage Techniques

The triage process involves a series of quick assessments and decisions. Medical personnel use a variety of techniques, including the START (Simple Triage and Rapid Treatment) method, which involves three simple questions: Is the patient breathing? Is the patient conscious? Is the patient walking? Patients who are conscious, able to walk, and have minor injuries are classified as walking and often do not require immediate treatment. Patients who are unconscious, unable to walk, or have severe injuries are typically classified as immediate or delayed.

Resource Allocation

Effective resource allocation is critical in mass casualty situations. Medical personnel must quickly assess the situation and allocate resources accordingly. This may involve prioritizing patients with life-threatening injuries, delegating tasks to other medical personnel, and implementing triage systems to manage the flow of patients. By allocating resources effectively, medical personnel can provide the best possible care to the greatest number of patients despite the limited availability of resources.
