Determining the mechanism of injury is crucial for first responders upon arrival at a trauma scene. Understanding the mechanism helps responders assess the potential extent and nature of the injuries sustained by the victim. This information is vital in making informed decisions about the necessary medical interventions and the urgency of transport to a medical facility.

Knowledge of the mechanism of injury allows responders to anticipate complications and prioritize care. For instance, if a victim was involved in a high-impact collision, there may be a higher likelihood of life-threatening injuries, such as internal bleeding or traumatic brain injury. This critical assessment enables emergency personnel to focus their efforts effectively and allocate resources accordingly.

Other actions, such as administering medications, transporting the patient, or gathering personal history, are important but typically occur after the mechanism of injury has been established and initial assessments have been made. Initially, responders need a clear understanding of the situation to provide the most effective care.
