FAST-ED Scale for Large Vessel Occlusion

Field Assessment Stroke Triage for Emergency Destination (FAST-ED). Identifies large vessel occlusion (LVO) stroke for prehospital triage to thrombectomy-capable centre.

Used in: Stroke & TIA

Score interpretation

LVO Less Likely 0–3

FAST-ED < 4 — lower probability of large vessel occlusion (NPV 82% at the ≥ 4 cut-off in the derivation cohort).

→ Route to nearest stroke centre; CT brain and standard stroke assessment

LVO Likely 4–9

FAST-ED ≥ 4 — sensitivity 60%, specificity 89%, PPV 72% for large vessel occlusion (Lima 2016).

→ Bypass nearest hospital if needed; route directly to thrombectomy-capable comprehensive stroke centre; pre-alert team

Interpretation bands for the FAST-ED. Apply clinical judgement and local guidance.
