A timeline of triage phases
| Pre-triage | Triage | Re-triage |
|---|---|---|
| Establish medical need/urgency (inclusion criteria and medical indication) | Clinical scores | Medical indication (benefit outweighing harm for individual patient)/medical futility |
| Medical futility (exclusion criteria) | Ranking (first-order criteria) | Patient will |
| Patient will (e.g. advance directive and proxy decision) | Tiebreaker (second-order criteria) | Benefit/need compared with other patients (including new arrivals) |
