Raum et al reported the Emergency Trauma Score (EMTRAS) for early estimation of trauma severity. The score can help to identify a patient who may benefit from more aggressive management. The authors are from the Polytraums Study Group of the German Trauma Society.
Patient selection: adult trauma patients
Parameters were selected that could be available within 30 minutes of arrival.
Parameters:
(1) age in years
(2) Glasgow Coma Score
(3) base excess in mmol/L (the more negative the number the greater the metabolic acidosis)
(4) percent prothrombin activity

where:
• The prothrombin activity can be estimated from a curve plotting prothrombin time versus percent activity.
total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 12
• The higher the score the more severe the trauma.
Performance:
• The area under the ROC curve was 0.83.
