Field Assessment Stroke Triage for Emergency Destination (FAST-ED)

Description

The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) can aid the assessment of a patient with a suspected stroke. It can help to identify patients with a large vessel occlusion stroke (LVOS). The authors are from multiple institutions in Brazil and the United States.

Patient selection: patient with suspected stroke prior to hospital transport

Parameters:

(1) facial palsy

(2) arm weakness

(3) voice change

(4) eye deviation

(5) denial/neglect

Parameters	Findings	Points
facial palsy	normal or minor paralysis	0
	partial or complete paralysis	1
arm weakness	no drift	0
	drift or some effort against gravity	1
	no effort against gravity or no movement	2
speech changes	absent	0
	mild to moderate	1
	severe, global aphasia or mute	2
eye deviation	absent	0
	partial	1
	forced deviation	2
denial/neglect	absent	0
	extinction to bilateral simultaneous stimulation in only one sensory modality	1
	does not recognize own hand or orients only to one side of the body	2

total score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 0

• maximum score: 9

• The higher the score the greater the chance of a large vessel occlusion stroke (LVOS).

Score	Percent LVOS
0	9%
1	13%
2	30%
3	32%
4	59%
5	70%
6 to 9	80%

Performance:

• The area under the ROC was 0.81.

• A score >= 4 has a sensitivity of 0.60 and specificity of 0.89.
