TRAGIC+ Score of Evans et al for Predicting Mortality of a Pediatric Patient After Trauma

Description

Evans et al reported the TRAGIC+ score for evaluating a pediatric patient after traumatic injury. It can help to identify a patient who may require more aggressive management. The authors are from the University of Texas Houston, University of Pennsylvania, Texas A&M University and University of Texas San Antonio.

Patient selection: 0 to 18 years status post trauma

Parameters:

(1) Glasgow Coma Scale (GCS)

(2) systolic blood pressure in mm Hg

(3) body temperature in °C

(4) sex

(5) race

(6) age

(7) injury type

(8) mechanism

poisoning	-1.313
suffocation	0.753
drowning or submersion	0.204
adverse effect medical care	-13.212
other	0.275

value of X =

= SUM(points for all of the parameters) + 2.866

probability of mortality =

= 1 / ( 1 + EXP((-1) * X))

Performance:

• The area under the ROC curve is 0.96.
