Unit
- Wilderness medicine: The practice of providing medical care in remote, resource-limited settings where definitive care may be hours or days away. It differs from urban emergency medicine by emphasizing prolonged care, improvisation, and evacuation planning.
- Provider roles: Wilderness medicine providers range from trained laypeople to medical professionals. Each operates within a defined scope based on training, certification, and local regulations. A wilderness first responder may initiate care but cannot perform invasive procedures.
- Key challenges: Limited equipment, environmental hazards, communication gaps, and psychological stress affect both patients and rescuers. Decision-making must balance patient needs with team safety.
- Evacuation timeline: In wilderness settings, transport to a hospital can take hours or days. Providers must plan for extended field care, including monitoring, shelter, and hydration.
- Legal framework: Good Samaritan laws protect providers acting in good faith without expectation of compensation. However, providers must not exceed their training or scope of practice.
- Medical direction: Many wilderness medicine protocols are developed with offline medical direction from physicians experienced in remote care. Standing orders guide treatments until communication is possible.
- Evidence base: Wilderness medicine relies on best available evidence, often extrapolated from urban studies and adapted for austere conditions. Research continues to evolve.
- Ethical principles: Autonomy, beneficence, nonmaleficence, and justice apply. In resource-limited settings, triage decisions may require prioritizing care for multiple casualties.
- Environmental hazards: Extreme temperatures, altitude, lightning, and wildlife encounters pose unique risks. Providers must integrate environmental assessment into every patient evaluation and adapt treatment plans accordingly, such as managing hypothermia in wet conditions or recognizing high altitude pulmonary edema.
- Patient assessment challenges: In wilderness settings, patient history may be unreliable due to altered mental status or language barriers. Physical exam is limited by lighting, weather, and lack of diagnostic tools. Providers rely on serial assessments and pattern recognition to detect changes over time.
- Resourcefulness and improvisation: Limited supplies force providers to improvise splints from trekking poles, use clothing for bandages, or create shelters from natural materials. Creativity and prior planning are essential to maintain sterility and function until evacuation.
Scope of Practice
Role: Wilderness First Responder (WFR)
Within scope:
- Conducting scene size-up and patient primary assessment
- Administering oxygen via non-rebreather mask
- Applying splints and bandages for extremity injuries
- Managing suspected spine injuries with cervical immobilization
- Communicating evacuation recommendations to incident command
Outside scope:
- Prescribing or administering prescription medications beyond standing orders
- Performing surgical procedures such as suturing or chest decompression
- Diagnosing specific medical conditions (e.g., pneumonia vs. bronchitis)
- Making definitive decisions to cancel evacuations without consultation
- Providing care beyond certification level without online medical direction
Terminology
- Definitive care
- Comprehensive medical treatment that resolves a condition, typically available at a hospital.
- Standing orders
- Pre-approved protocols allowing specific interventions without direct physician contact.
- Good Samaritan law
- Legal protection for providing reasonable emergency care without expectation of reward.
Quick Revision
- Wilderness medicine addresses medical care in remote settings with limited resources.
- Providers operate within defined scopes; exceeding them risks legal and ethical consequences.
- Evacuation timelines require extended field care planning.
- Good Samaritan laws provide protection but do not permit scope violations.
