The Triage supplement to the TCCC Guidelines presents a comprehensive guide to improve Mass Casualty Management (MCM) across the military continuum, emphasizing an integrated, command-directed approach to synchronize medical and nonmedical efforts. The MCM is not merely about casualty care but about managing an incident with limited resources, chaotic conditions, and diverse responder capabilities.
MCM is a leadership responsibility that includes coordinated planning, security, triage, treatment, communication, casualty movement, and evacuation. Nonmedical personnel—who are often the first responders—are critical in casualty care and system effectiveness, especially in far-forward or resource-limited settings.
MASCAL incidents are inherently unpredictable, dynamic, and overwhelming. These events can range from a dozen casualties to thousands, often disrupting preplanned capabilities. Factors like mechanism of injury, time to surgery, responder expertise, and environmental threats heavily influence triage priorities and casualty outcomes.
A classification model proposes three MASCAL classes:
MCM is expected to include preplanned casualty collection points (CCPs), adaptable evacuation plans (PACE), and procedures for expectant and end-of-life care.
The supplemental guideline recommends a two-pass triage approach based on TCCC principles:
Importantly, time is a triage tool—interventions like tourniquet application within minutes can be lifesaving, while delays in damage control surgery or blood transfusions (>1 hour) reduce survival odds significantly.
Expectant Casualty Care (ECC) is treated as a legitimate category, emphasizing comfort and re-triage over time. Ethical and psychological considerations are discussed, particularly for leadership and care teams making difficult prioritization decisions.
Effective MCM requires extensive planning that includes:
Training recommendations call for holistic, team-based scenarios involving command-level personnel, not just medical staff. Stress is placed on simulation fidelity, standard objectives, and performance outcomes (e.g., “all hemorrhagic shock patients received transfusion within 30 minutes”).
The supplemental guideline outlines detailed CCP setup principles, security protocols, and communication frameworks (internal and external). Movement of casualties must be addressed in both tactical and operational contexts, with thoughts on optimizing evacuation load plans, protecting human remains, and resource consolidation.
Additionally, support roles like the Unit Ministry Team (UMT) are incorporated into the model for spiritual and emotional care.
TCCC Triage advocates for a standardized, leader-driven, team-centric, and scenario-adaptable MCM system and stresses that preparedness—not perfection—is the cornerstone of success. Realistic training, frequent rehearsal, and integration of medical and nonmedical domains are required to transform chaos into coordinated response and improve outcomes in mass casualty events.
