frequent flyer
What does frequent flyer mean?
ED slang for the patient who's back again, and again, and again. Sometimes it's chronic illness with no GP to fall back on. Sometimes it's mental health, addiction, or nowhere else to go. Sometimes it's just somebody who's worked out where the warmth and sandwiches are. Officially called 'super-utilisers' in polite write-ups; staff just say frequent flyer. A small handful drive a huge slice of total visits — one San Diego hospital found 3% of patients accounted for 16.5% of ED traffic.
Origin
Borrowed from airline loyalty programmes; widespread in US/UK emergency medicine since the 90s.
