Emergency medicine is the medical specialty with the principal mission of evaluating, managing, treating and preventing unexpected illness and injury. It encompasses a unique body of knowledge, reflected in the "Model of the Clinical Practice of Emergency Medicine."1 Clinical emergency medicine may be practiced in emergency departments, urgent care clinics, and other settings. The clinical practice of emergency medicine encompasses the initial evaluation, treatment, and disposition of any person at any time for any symptom, event, or disorder deemed by the person - or someone acting on his or her behalf - to require expeditious medical, surgical, or psychiatric attention.
Emergency medicine provides valuable clinical and administrative services to the health care delivery system, including care for individuals who lack other access to health care, pre-hospital care planning and medical control, and patient-care coordination - across venues and among providers. Consequently, emergency medicine serves as America's health care safety net. Emergency physicians develop a deep understanding of health care systems and are uniquely positioned to plan, implement, and evaluate them.
