Emergency Department

An emergency department (ED), also known as accident & emergency (A&E), emergency room (ER), or casualty department, is a medical treatment facility specialising in acute care of patients who present without prior appointment, either by their own means or by ambulance. The emergency department is usually found in a hospital or other primary care centre.

Due to the unplanned nature of patient attendance, the department must provide initial treatment for a broad spectrum of illnesses and injuries, some of which may be life-threatening and require immediate attention. In some countries, emergency departments have become important entry points for those without other means of access to medical care.

The emergency departments of most hospitals operate 24 hours a day, although staffing levels may be varied in an attempt to mirror patient volume.

Famous quotes containing the words emergency and/or department:

    War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.
    Susan Sontag (b. 1933)

    ... the Department of Justice is committed to asking one central question of everything we do: What is the right thing to do? Now that can produce debate, and I want it to be spirited debate. I want the lawyers of America to be able to call me and tell me: Janet, have you lost your mind?
    Janet Wood Reno (b. 1938)
