Kahnamoui et al reported the TRAAGIC score for predicting inpatient mortality for a trauma patient. The authors are from McMaster University and Hamilton Health Services in Canada.
TRAAGIC = transfusion, age, airway, hyperglycemia, INR, creatiniine
Patient selection: adult trauma patient
Parameters:
(1) transfusion (TR)
(2) age (A)
(3) airway (A), with or without endotracheal intubation
(4) blood glucose (G) on arrival, in mmol/L
(5) INR (I)
(6) serum creatinine (C) within first 24 hours, in µmol/L

unweighted score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum unweighted score: 0
• maximum unweighted score: 6
• The higher the score the greater the risk of inpatient mortality.
