Overview :
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

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.
