Your First A&E Visit: What to Expect Step by Step

Overview

Walking into an Accident & Emergency department for the first time can be overwhelming. The environment is clinical and busy, there are multiple waiting areas, and the process involves several stages that are not always explained clearly. This guide takes you through every step from arrival to departure so you know what to expect and can prepare accordingly.

If you are bringing a child, our parent's guide to A&E covers additional considerations specific to paediatric departments. For older adults, our elderly A&E guide addresses mobility, medication and communication concerns.

Stage 1 — Arriving and checking in

When you walk through the main entrance, look for the reception desk. In busy departments there may be a short queue. A receptionist will ask for your basic details:

• Full name and date of birth
• Home address and a contact phone number
• NHS number (if you know it — do not worry if you do not)
• GP surgery name
• A brief description of why you are here

If paramedics brought you in by ambulance, they handle this handover directly with the clinical team. You skip reception entirely and are taken into the department by the ambulance crew, who pass your details and observations to the receiving nurse.

It is worth having your information ready before you reach the desk. Our what to bring guide covers the full list of useful documents and items.

Stage 2 — Triage assessment

A senior nurse — usually called the triage nurse — will see you shortly after check-in. The national target is within 15 minutes of arrival, though it can be faster or slower depending on how busy the department is. During triage, the nurse will:

• Measure your vital signs: blood pressure, pulse rate, temperature, blood-oxygen level (using a small clip on your finger) and respiratory rate
• Ask targeted questions about your symptoms: when they started, how they have changed, what makes them better or worse
• Ask about your medical history, current medications and allergies
• Examine the affected area if appropriate

Based on this assessment, you receive a clinical priority category. This category — not the clock on the wall or your position in any physical queue — determines when a doctor or advanced practitioner sees you. Our triage guide explains each category in detail, including typical wait targets for each level.

It is important to be honest and specific during triage. Downplaying your symptoms might result in a lower priority than your condition warrants; exaggerating them can lead to tests and interventions you do not need.

Stage 3 — The waiting room

After triage, you return to the waiting room until a clinician becomes available for your priority level. This is often the longest single wait in the process, and a few things are worth knowing:

Your place in the order depends on your triage category, when you were triaged relative to others in the same category, and how many clinicians are available. Two patients triaged at the same level will generally be seen in arrival order, but a new arrival assessed as more urgent will rightly be seen first.

You can step out briefly — for the toilet, to get fresh air or to fetch something from the car — but tell reception before you go so they know where to find you. If your name is called while you are away, staff will usually try once more before moving on.

If your symptoms change for the worse while you are waiting — new chest pain, sudden dizziness, vomiting, spreading numbness, worsening breathing — tell staff immediately. Walk to the triage desk and explain what has changed. You may be re-assessed and moved to a higher priority. Do not sit and wait in the hope that someone will notice from across the room.

Expect the wait to feel longer than it is. Hospitals are stressful environments, and anxiety stretches the perception of time. Having something to occupy you — a book, a podcast, a phone charger — helps. Our guide on reducing your A&E wait has practical tips for managing the time productively.

Accompaniment. You are entitled to have someone with you for support. If you are a child, a parent or legal guardian should stay. Some departments limit the number of visitors in the waiting room during busy periods, but a single accompanying person is almost always allowed.

Stage 4 — Clinical assessment and treatment

When your turn comes, a doctor, emergency nurse practitioner or physician associate will call you through. You may be taken to a curtained cubicle, a private room, or an assessment bay depending on your condition and what is available.

The clinician will take a more detailed history than triage, asking about:

• The exact timeline and nature of your symptoms
• Your full medical history, including operations, chronic conditions and family history
• All current medications, doses and when you last took them
• Allergies — both medications and other substances
• Social context — who you live with, whether you can manage at home, whether you drove yourself

They will then examine you and may order investigations:

• Blood tests — a nurse or phlebotomist takes samples, which are sent to the hospital laboratory. Results typically come back within 30 to 90 minutes depending on what was ordered.
• X-rays — you may be sent to the radiology department within the hospital. Wait times vary but are typically 15 to 45 minutes for the X-ray itself, with results reviewed shortly after.
• ECGs — a quick heart tracing done at the bedside, results available immediately
• CT or MRI scans — less common in A&E, reserved for suspected strokes, significant head injuries, pulmonary embolisms and similar. These take longer to arrange.
• Urine or swab samples — for suspected infections

The clinician may also begin immediate treatment: pain relief, wound cleaning and closure, splinting a fracture, starting intravenous fluids or medications.

Stage 5 — Waiting for results

If tests have been ordered, there is another wait while results come back. This can feel frustrating because you have already waited once, but it is a necessary part of the diagnostic process. Typical turnaround times:

• Blood tests: 30–90 minutes for routine panels, longer for specialised tests
• X-ray reports: 15–60 minutes
• CT scans: the scan itself takes minutes, but the radiologist's report may take 30–60 minutes
• Urine cultures: preliminary results in hours, full culture in 24–48 hours (but A&E does not usually wait for the full culture)

During this wait, your cubicle may be needed for another patient. You might be asked to return to the waiting room or moved to a different area. This does not mean you have been forgotten — your results will be tracked by the system.

Stage 6 — Decision and outcome

Once the clinical picture is clear, one of several things happens:

Discharge home. The most common outcome. You leave with:

• A diagnosis or working diagnosis
• Written or verbal advice about self-care and recovery
• A prescription if medications are needed (either to collect from the hospital pharmacy or your local pharmacy)
• Instructions about when to seek further medical help — the "safety net" advice
• A follow-up plan: this might be a referral letter for your GP, an outpatient clinic appointment, or advice to return if symptoms worsen

Read our after A&E discharge guide for what to expect in the days following your visit.

Admission to a ward. If your condition requires ongoing treatment, monitoring or surgery, you will be admitted. The A&E team arranges a bed on an appropriate ward, which can involve another wait if the hospital is full.

Transfer to another hospital. Occasionally, the specialist service you need is at a different site. The A&E team arranges ambulance transfer and communicates your details to the receiving hospital.

Referral to a specialist team within the hospital. You may stay in the A&E department while a specialist — such as an orthopaedic surgeon, cardiologist, or mental health team — comes to assess you.

How long does the whole process take?

The NHS operational standard aims for 76 per cent of patients to be admitted, transferred or discharged within four hours of arrival. In practice, many visits run longer. National data shows the median time for patients who go home is around 3 to 4 hours, while those admitted to a ward spend 6 to 8 hours in A&E on average.

Your actual time will depend on how busy the department is, what investigations you need, and whether you are waiting for a specialist opinion or a ward bed. You can get a sense of how busy departments are near you by checking our live wait time tracker.

Your rights during the visit

You have the right to be treated with dignity, to have your condition explained in language you understand, and to consent to or refuse treatment. If you have concerns about your care at any point, you can ask to speak to a senior clinician or the nurse in charge. Our patient rights guide covers this in full.

What to take away

A&E involves multiple sequential waits, and the total time is rarely under two hours even for straightforward cases. Preparing properly — bringing your medications list and essentials, being clear during triage, and understanding the stages — will make the experience considerably smoother. If your condition is not an emergency, consider whether an Urgent Treatment Centre or NHS 111 might get you treated faster.
