Which category of Mechanism of Injury (MOI) includes environmental factors?

The category of Mechanism of Injury (MOI) that includes environmental factors is the one that focuses specifically on how environmental elements can impact a person's health and safety. Environmental factors can include natural occurrences such as extreme weather conditions, terrain hazards, exposure to elements like heat or cold, and other external conditions that can lead to injuries or health issues.

Understanding the role of environmental factors is essential for wilderness first responders as these factors can significantly influence patient assessment and management. For instance, a hiker suffering from hypothermia is experiencing an injury directly related to environmental conditions, emphasizing the importance of recognizing and addressing the environment's role in MOI.

In contrast, trauma is more focused on physical injuries typically resulting from direct external force, while medical pertains to illnesses or conditions not influenced directly by external environmental factors. Psychological refers to mental health issues, which do not stem from physical mechanisms like environmental exposures. Thus, the environmental category is crucial as it encompasses the unique challenges faced in wilderness settings.
