FAST-ED (field LVO triage)
Field Assessment Stroke Triage for Emergency Destination (Lima 2016).
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Facial palsy
- Partial or complete paralysis (1)
- Arm weakness
- No effort against gravity / no movement (2)
- Speech changes
- Severe, global aphasia, or mute (2)
- Eye deviation
- Absent (0)
- Neglect
- Absent (0)
Result: FAST-ED 5/9: a total >= 4 predicts a large-vessel occlusion -- supports comprehensive-stroke-center triage per protocol.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Threshold
- a total of 4 or more predicts a large-vessel occlusion and supports comprehensive-center triage (sensitivity ~0.60, specificity ~0.89, PPV ~0.72).
What you enter
- Facial palsy
- Arm weakness
- Speech changes
- Eye deviation
- Neglect
How this is calculated
- Components
- Facial palsy (0-1), Arm weakness (0-2), Speech changes (0-2), Eye deviation (0-2), Denial/Neglect (0-2); total 0-9.
