Prehospital Acute Stroke Severity (PASS) Scale of Hastrup et al

Description

Hastrup et al reported the Prehospital Acute Stroke Severity (PASS) scale for the prehospital evaluation of an acute stroke patient. This can help to identify a patient who has a large artery occlusion. The authors are from Aarhus University in Denmark.

Patient selection: acute stroke

Parameters (taken from the NIHSS):

(1) responses to the level of consciousness (LOC) questions (month, age)

(2) gaze palsy and/or deviation

(3) arm weakness

Parameter	Finding	Points
LOC questions	2 correct	0
	0 or 1 correct	1
gaze palsy/deviation	none	0
	any	1
arm weakness	none	0
	any	1

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 3

• A score >=2 is associated with a large artery occlusion.

Performance:

• The area under the ROC was 0.74.
