ACS COT Field Triage Guidelines

EMS TRIAGEACS COT Field Triage

Step 1: Physiology

GCS ≤ 13, SBP < 90 mmHg, or abnormal Respiratory Rate

Criteria Present?

Step 2: Anatomy

Penetrating injury, flail chest, amputation, crushed limb, etc.

Criteria Present?

Step 3: Mechanism

Falls > 20ft, high-risk crash, auto vs ped > 20mph

Criteria Present?

Step 4: Considerations

Age, anticoagulation, pregnancy, or EMS judgment

Criteria Present?

Awaiting Field Data

Select any positive criteria from Physiology, Anatomy, Mechanism, or Special Considerations.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

All injured patients evaluated in the prehospital setting (EMS, first responders)

Blunt or penetrating trauma of any mechanism

Patients requiring decision-making regarding destination trauma facility

Mass casualty triage systems (adapted use)

Interfacility transfer triage reassessment

Rural and urban trauma systems to optimize resource allocation

Purpose of the Guidelines

Objective	Clinical Impact
Identify severe injury (ISS ≥ 15)	Ensures transport to trauma centers
Reduce undertriage	Prevents missed critical injuries
Minimize overtriage	Avoids unnecessary trauma center burden
Standardize EMS decisions	Improves system-wide efficiency

Limitations

Primarily designed for prehospital use—not definitive hospital diagnosis

Sensitivity favored over specificity (intentional overtriage)

Less accurate in elderly and pediatric populations

Does not replace clinical judgment

May underperform in low-energy mechanisms (e.g., ground-level falls in elderly)

Key Principle

The Field Triage Guidelines prioritize early identification of potentially life-threatening injuries using a stepwise algorithm: physiologic criteria → anatomic criteria → mechanism of injury → special considerations.
