Rule of Thumb of Nelson et al for Outcome for a Patient with Traumatic Brain Injury (TBI)

Description

Nelson et al reported a rule of thumb for predicting the outcome for a patient with traumatic brain injury (TBI). The authors are from Karolinska Institute in Stockholm and Imperial College London.

Patient selection: adult with traumatic brain injury

Parameters:

(1) age in years

(2) Glasgow coma scale (GCS)

(3) midline shift in mm

(4) "10 rule"

(4a) nonresponsive pupils

(4b) subarchnoid and/or intraventricular hemorrhage

(4c) diffuse axonal injury

(4d) epidural hemorrhage

Parameter	Finding	Points
age in years		(age)
GCS		- 3 * (GCS)
midline shift		(shift in mm)
nonresponsive pupils	absent	0
	present	10
subarachnoid and/or intra-ventricular hemorrhage	absent	0
	present	10
diffuse axonal injury	absent	0
	present	10
epidural hemorrhage	absent	0
	present	-10

total score =

= SUM(points for all of the parameters)

final score =

= MIN(100, MAX(0, score))

Interpretation:

• The total score reflects the probability of an unfavorable outcome (Glasgow outcome scale of 1, 2 or 3).
