In the context of trauma, what is the mechanism of injury (MOI)?

The mechanism of injury (MOI) refers specifically to the process or method by which a patient has sustained their injuries. Understanding the MOI is crucial for medical professionals because it provides insight into the forces that caused the injuries, which can influence diagnosis, treatment, and prognosis. For example, knowing whether a patient was involved in a high-velocity motor vehicle collision or a low-energy fall can help in anticipating types of injuries and the potential for specific complications.

This focus on the way injuries occurred allows healthcare providers to create a more effective assessment and treatment plan, ensuring that they address not only the visible injuries but also the underlying issues that may not be immediately apparent.
