Triage
Also known as: Emergency triage, Patient prioritisation, Manchester Triage System, ESI (Emergency Severity Index)
Triage is the process hospitals use to prioritise patients by urgency — it determines how long you wait.

Real-world example
You're in a hospital A&E in Barcelona with a suspected broken wrist. At the triage desk, a nurse checks your pain level, takes your vitals, and assigns you a category. You wait 3 hours. Meanwhile, a patient who arrived after you with chest pain is taken straight through. Nothing went wrong — triage worked exactly as designed.
Why travellers need to know
Triage systems vary between countries, and visitors who don't understand the process often assume long waits mean they've been forgotten. In reality, being made to wait is good news — it means your condition isn't life-threatening. Knowing how triage works helps you stay calm, communicate your symptoms clearly at the triage desk, and understand that arrival order has no bearing on treatment order.
Country-specific notes
Manchester Triage System: 5 urgency categories
UK emergency departments use the Manchester Triage System. Category 1 (immediate, life-threatening) is seen within seconds. Category 3-4 (urgent but stable) can wait 2-4 hours. NHS A&E treats everyone regardless of residency or insurance.
Tip
NHS 111 (phone or online) can assess whether you need A&E at all. Many conditions can be handled by a walk-in urgent care centre with shorter waits.
