What Happens if You Leave A&E Prematurely?

It is a question many people ask after sitting for six hours in a plastic chair: “Can I leave A&E without being seen?” The short answer is yes.

An Accident & Emergency department is not a prison, and as an adult with mental capacity, you have the legal right to leave at any time. However, while no one will physically stop you, leaving “Against Medical Advice” (AMA) carries significant risks.

Before you grab your coat, here is everything you need to know about the process, the statistics, and the medical implications of walking out.


So. What Happens if You Leave A&E Prematurely?

If you decide the wait is simply too long, the hospital has a standard procedure they must follow:

1. The Self-Discharge Form

If you inform the staff you are leaving, they will likely ask you to sign a “Self-Discharge Form.” This document legally protects the hospital by confirming that you are leaving against their recommendation and that you understand the potential risks to your health.

2. Removal from the Triage System

The moment you leave, you are taken off the A&E clinical system. This means you lose your place in the queue. If you change your mind two hours later because your pain has worsened, you will have to check in again and start the waiting process from the very beginning.

3. Notification of Your GP

In many cases, the hospital will send an electronic note to your GP stating that you attended A&E but left before being seen. This is done to ensure there is a “paper trail” for your medical safety.


Is It Wise to Leave? The “Wait vs. Risk” Balance

At MyHSN, our general advice is: Try to stick it out. While the wait times are frustrating, there are several reasons why staying is usually the safer bet:

  • The “Weekend Gap”: If you leave A&E on a Friday night or a Saturday, you may find it impossible to get a GP appointment until Monday or Tuesday. A&E is often the only place to get definitive care during weekends and bank holidays.

  • Hidden Dangers: Some conditions (like internal bleeding or certain cardiac issues) can feel manageable at first but deteriorate rapidly. By staying, you are in the safest possible place if things take a turn for the worse.

  • Diagnostic Tools: A&E has immediate access to X-rays, CT scans, and blood labs that a GP surgery does not. Leaving means delaying these vital tests.

A Note on Triage: If you have been waiting for a very long time, it usually means the “Triage Nurse” has categorized your vitals as stable. While this is frustrating, it is actually a good sign—it means you aren’t currently considered to be in immediate life-threatening danger.


Why More People are Walking Out (The Stats)

You are not alone in your frustration. Recent data shows a sharp rise in “left before being seen” (LBBS) rates in the UK:

  • In 2019: Only 2% of patients left A&E without completing their treatment.

  • By 2024: This number jumped to 5%.

This increase is a direct reflection of the mounting pressure on the NHS and the resulting 8-to-12-hour wait times in many urban departments.


Alternatives: What Should You Do Instead?

Before you walk out the door, consider these steps:

  1. Speak to the Triage Nurse: Ask for an update. Say: “I’ve been here for six hours and I’m struggling. Is there an estimated time for me to be seen?” While they can’t always be precise, they can re-check your symptoms.

  2. Call a Friend: Sometimes having someone to talk to or bring you a charger/snack can make the final few hours of a long wait more bearable.

  3. Check 111 Online: If you truly feel you can leave, check the NHS 111 website first. They may be able to book you into an Urgent Treatment Centre (UTC) or a “Minor Injuries Unit,” where the wait times are often significantly shorter than a major A&E.


Summary: Should You Leave?

If you feel well enough to walk out and drive home, it is a sign that your condition might not have been a true “emergency.” However, if you originally went to A&E because you were scared or in significant pain, staying is the only way to get a definitive diagnosis.
