Wikipedia defines Emergency medicine (also known as accident and emergency medicine) as: The medical specialty concerned with caring for undifferentiated, unscheduled patients with illnesses or injuries requiring immediate medical attention. In their role as first-line providers, emergency physicians are responsible for initiating resuscitation and stabilization, starting investigations and interventions to diagnose and treat illnesses in the acute phase, coordinating care with specialists, and determining disposition regarding patients' need for hospital admission, observation, or discharge.
Emergency physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units, but may also work in primary care settings such as urgent care clinics.
