TRIAGE • 18TH century French: Trier = to separate out
• Minimal use until 1970’s
• Assign degrees of urgency to wounds/illness to
decide order of treatment in large group
• Rations treatment efficiently when resources are
insufficient to treat all
• Sorting based on need or likely benefit

Over Triage and Under Triage
• Overestimating
injuries
•
• Goal: 25-30%
• Discharge w/in 24/48 h
• No Surgery
• No ICU
• No Blood
• ISS less 15
• Underestimating
degree or urgency of
injuries
• Goal: less 5%
• Needed Resources
but didn’t get them
