Algorithm of Follin et al for Prehospital Triage of a Polytrauma Patient

Description

Follin et al reported a tree-based algorithm for prehospital triage of a patient with polytrauma. The authors are from Universite Paris 5 Descartes, University of California San Francisco, Universite Paris Diderot, Universite de Versailles St Quentin and the University of California Berkeley.

Patient selection: polytrauma

Outcome: percent of patients who need to be referred to a trauma center

Parameters:

(1) need for mechanical ventilation

(2) spinal cord injury

(3) mechanism of trauma (penetrating, fall, blunt)

(4) hemoglobin in g/dL

(5) heart rate in beats per minute

(6) sex

(7) age in years

(8) type of crash (pedestrian, car, motorcycle)

(9) systolic blood pressure in mm Hg

(10) percent oxygen saturation

N	N	blunt	<= 11.5	100-120	F	> 27				12

N	N	blunt	> 11.5	<= 99				<= 99	> 95	16
N	N	blunt	> 14.1	<= 99					<= 95	17
N	N	blunt	11.6-14.1	<= 99					<= 95	18
N	N	blunt	<= 11.5	<= 99						19

where:

• The original spinal cord determination was for fall and penetrating injury. Added blunt as well.

• The type of crash listed is pedestrian, car and motor cycle. None is not an option in the original table.
