Wilderness medicine is the practice of medicine, typically in austere conditions and environments, with limited resources. Wilderness medicine has many overlaps with various aspects of emergency medicine, such as pre-hospital/EMS, disaster medicine, sports medicine, dive and hyperbaric medicine, global health, trauma, etc., and has a wide range of practice areas from the true backcountry, to the heart of a metropolis. The practice of wilderness medicine focuses on the pathophysiology and injury patterns that patients encounter in these environments. The wilderness provider learns to hone her skills through focus on not only strong clinical judgment based on a firm educational foundation, but also improvisational skills to efficiently triage, stabilize, evacuate, and otherwise provide care to patients in a resource-poor environment.
