Model of Nemunaitis et al for Early Prediction of Functional Impairment After Trauma

Description

Nemunaitis et al reported a model for predicting funcitonal impairment after trauma. This can help to identify a patient who may have more severe disability. The authors are from Case Western Reserve University and MetroHealth Medical Center in Cleveland.

Patient selection: major trauma

Outcome: Functional Independence Measure (FIM), with maximum score 126

Parameters from the linear regression model:

(1) age in years

(2) gender

(3) race

(4) marital status

(5) insurance

(6) injury severity score (ISS, from 0 to 75

(7) drug/alcohol test

(8) Glasgow coma scale

(9) systolic blood pressure

(10) injury type

(11) intubation at scene

(12) time of the squad at the scene in minutes

Parameter	Finding	Points
age in years		-0.286 * (age)
gender	female	0.365
	male	0
race	non-white	-0.076
	white	0
marital status	married	0.636

drug/alcohol test	negative	0

GCS		0.488* (GCS)
systolic blood pressure	< 90 mm Hg	-2.634
	>= 90 mm Hg	0
injury type	blunt	-0.455
	penetrating	0
intubated at scene	no	0
	yes	-4.590
scene time in minutes		0.023 * (time)

score =

= SUM(points for all of the parameters) + 103.93

Interpretation:

• The higher the FIM score the better the functional outcome.
