What is the emergency room (ER)?
An emergency room (ER)—or emergency department—is a place where you go for a medical emergency. It's not for routine health care. An ER is often open 24 hours a day. You don't need an appointment.
What should you consider when choosing an emergency room?
In an emergency, it's usually best to go to the nearest emergency room (ER). But if there are several in your area, it's good to do some comparisons ahead of time.
Ask your doctor if some ERs have different medical equipment or services, such as a trauma center. Ask your doctor which ER they would take a family member to.
