A & E stands for Accident and Emergency, and “A & E department” is simply the fuller name for the same place. It is the part of a hospital that treats people who arrive with sudden, serious, or urgent medical problems — the unit you turn to in an emergency, day or night, without an appointment.

The abbreviation is used mainly in the UK and Ireland. It is the front door of the hospital for emergencies, open 24 hours a day, every day of the year, and it accepts anyone who walks in or is brought in by ambulance, regardless of whether they have seen a doctor before.

What it’s for

The A & E department is designed for situations that cannot safely wait for a normal doctor’s appointment. Typical reasons people go include:

• Serious injuries from accidents — broken bones, deep cuts, burns, or head injuries
• Chest pain or difficulty breathing
• Severe or uncontrolled bleeding
• Loss of consciousness or fainting
• Signs of a stroke (sudden weakness, slurred speech, drooping face)
• Signs of a heart attack
• Severe allergic reactions
• Sudden, severe illness, high fever in vulnerable people, or a serious worsening of an existing condition

It is not meant for minor problems that a family doctor (GP), pharmacist, or walk-in clinic could handle — such as a mild cold, a small rash, or a repeat prescription. Using A & E for non-urgent issues adds to crowding and longer waits for everyone.

How it works

When you arrive, you don’t simply wait in line. A nurse usually assesses you first in a process called triage. This sorts patients by how urgent their condition is, rather than by who arrived first. Someone with a life-threatening problem is seen ahead of someone with a minor injury — which is the main reason waiting times can feel long and unpredictable.

After triage, the typical path looks something like this:

1. Registration — your details and the reason for your visit are recorded.
2. Assessment — a doctor or specialist nurse examines you and may order tests.
3. Tests — these can include blood tests, X-rays, or scans to find out what’s wrong.
4. Treatment — you might be treated and sent home, kept for observation, referred to a specialist, or admitted to a hospital ward if you need to stay.

Many A & E departments work alongside an ambulance service, a resuscitation area for the most critical patients, and minor injuries sections for less severe cases.

A note on names

The same kind of department goes by different names around the world, even though the job is essentially identical:

• United States → Emergency Room (ER) or Emergency Department (ED)
• UK & Ireland → A & E, sometimes still called Casualty
• Many other countries → Emergency Department or the local equivalent

So if you hear “ER” in an American film and “A & E” in a British one, they’re talking about the same place.
