MOI stands for which term in trauma assessment?

• A. Mode of Injury
• B. Mechanism of Injury
• C. Magnitude of Injury
• D. Management of Injury

Answer: (B)

Mechanism of Injury is what MOI stands for in trauma assessment. It describes how the injury occurred—the event, forces, and energy transfer involved. Understanding the mechanism helps you anticipate injuries that may not be immediately obvious, guide the physical exam, and inform triage and transport decisions. For example, high-energy mechanisms like a high-speed vehicle crash or a fall from height raise concern for multi-system trauma and hidden injuries, while penetrating injuries have different risk profiles. While the term may seem similar to others, the standard meaning in trauma care is Mechanism of Injury, and the other options don’t reflect this concept.
