The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) score was developed in the hospital setting to be used in the prehospital setting. It has been shown to have higher predictive value than comparable stroke scales, including the National Institutes of Health Stroke Scale, for identifying large vessel occlusion strokes. ⋯ The findings validate that prehospital FAST-ED scores are comparable in predictive value to FAST-ED scores calculated in the ED for prediction of large vessel occlusion strokes.
