Emergency Triage: How Paramedics Prioritise Care When Every Patient Is Critical

What happens when there are many people injured from a severe accident? This is when paramedics face the realisation that not everyone can be treated at once. Read on to discover how care is prioritised when every patient is critical.

What is Triage?

Triage is the process used to determine the order of priority for providing treatment to casualties in multi-injury incidents. The urgency of deciding who will receive treatment first requires consideration of various factors. For instance, the severity of the injuries, the rate of survival and how the treatment will be administered.

Triage is an essential part of emergency trauma support, where it allows response teams to prioritise limited resources, such as medical supplies, time, personnel, and transport, when your survival depends on it. It is also a multilayered process because your triage category can change as your condition improves or deteriorates.

When and Where Is Triage Used?

Triage often works differently depending on whether you are still at the scene or in the hospital. There’s a criterion that assesses the patterns of each injury, vital signs and mental status to decide whether you fall in a high-risk level. This classification process isn’t limited only to large-scale incidents and can be used in:

• Motor vehicle accidents with multiple casualties.
• Natural disasters like floods, earthquakes, and fires.
• Terror attacks or mass shootings.
• Overburdened emergency departments.
• Disease outbreaks or pandemics.

Types of Triage Systems

There are several established triage models, each adapted to specific environments and emergency response systems. The most used in the field include:

1. START (Simple Triage and Rapid Treatment)

Widely used in mass casualty situations, START helps responders quickly categorise patients into four colour-coded groups:

• Red (Immediate) – Life-threatening but treatable injuries requiring rapid intervention.
• Yellow (Delayed) – Serious injuries that need care but are not immediately life-threatening.
• Green (Minor) – Walking wounded with minor injuries who can wait or self-evacuate.
• Black (Deceased/Expectant) – Victims who are fatal or whose injuries are so severe that survival is unlikely with available resources.

This system relies on quick assessments of breathing, circulation, and mental status. It allows responders to process large numbers of patients in minutes.

2. SALT (Sort, Assess, Lifesaving Interventions, Treatment/Transport)

An updated alternative to START, SALT adds a sorting step before triage and allows for lifesaving interventions on-site (such as airway opening or tourniquet application) before assigning a category.

3. Emergency Department Triage

In hospital settings, nurses use a more detailed 5-level triage system, such as the Emergency Severity Index (ESI), to determine the order in which patients are seen and the resources they’ll require.

How Paramedics Perform Triage on the Scene

When dealing with challenges associated with multiple casualties, paramedics must follow this approach:

1. Scene Assessment

They must ensure the area is safe for responders and assess the overall scale of the incident. This includes estimating the number of people injured and determining whether they will require additional resources.

2. Triage Officer Assignment

A senior paramedic or specially trained responder may be designated as the triage officer, taking charge of patient classification while others focus on lifesaving interventions.

3. Rapid Triage

Based on specific signs, patients are tagged with a colour or triage card. In some systems, patients may receive barcoded tags for digital tracking. Using different protocols like START or SALT can help assess each patient for:

• Obstructed airway passages.
• If the respiratory rate is fast or slow.
• Perfusion to assess their pulse and whether there’s internal bleeding.
• The degree of their mental status and whether any signs of head trauma are present.

4. Reassessment

As more personnel arrive and conditions stabilise, patients are re-triaged. A red-tagged patient may deteriorate or stabilise; a yellow may become red. Triage is fluid.

The Ethics and Burden of Triage

Triage means making hard choices that can feel wrong to people trained to save every life, like giving a black tag to someone who is still breathing but too badly hurt to help without using up all the resources. These choices are made to help as many people as possible, and paramedics in many countries practise for this with special training and drills. It’s not about who deserves care; it’s about who is most likely to survive and how to use limited help in the best way.

Triage is made to be fast, clear, and focused on saving lives. It helps keep things organised during big emergencies. It ensures that people with the best chance of survival receive help first. In contrast, others are assisted as more support becomes available. Even though it may appear chaotic from the outside, trained paramedics and first responders dispatched by Affinity Rescue are making careful, informed decisions to help save your life.
