EMS physicians transport themselves to the scene, rather than the scene being brought to them as in standard medical practice. They many times initially perform the functions their triage nurse otherwise would, in a deliberate and expedited fashion. Patients in the field are seen at first in parallel rather than in series. The physician is given the opportunity to see the scene as a reflection of the general health of the patient, or as a first-hand account of mechanism of injury. Consequently, the physician is subject to the unique environmental dangers associated with patient care in the field that often contributed to, or are a result of, the patient’s injury or illness. A successful EMS physician in active field operations assesses the scene, acts on this assessment, and mitigates danger prior to the provision of any patient care or evaluation.
