Prehospital Index (PHI) | Medicalalgorithms.com

Description

The Prehospital Index (PHI) is a trauma severity scoring system intended for triaging patients by emergency response personnel at the site of injury.

Parameters:

(1) systolic blood pressure

(2) pulse rate

(3) respiratory rate

(4) consciousness

(5) penetrating wounds to chest and/or abdomen

Parameter	Finding	Points
systolic blood pressure	> 100 mm Hg	0
	86-100 mm Hg	1
	75-85 mm Hg	2
	0-74 mm Hg	5
pulse	51-119 beats per minute	0
	>= 120 beats per minute	3
	<= 50 beats per minute	5
respirations	normal	0
	shallow and/or labored	3
	< 10 per minute, or intubated	5
consciousness	normal	0
	confused and/or combative	3
	no intelligible words	5
penetrating wounds to chest and/or abdomen	none	0
	present	4

prehospital index =

= (points for systolic blood pressure) + (points for pulse) + (points for respirations) + (points for consciousness) + (points for penetrating wounds)

Interpretation:

• maximum score (indicating most affected): 24

• minimum score (indicating least affected: 0

• A score > 3 indicates major trauma.

• A score <= 3 indicates minor trauma.
