trauma injury severity score

ABBR: TRISS. A calculation of the probability that an injured person will survive serious trauma. It is made on the basis of the patient’s age, the type of trauma (blunt versus penetrating), and the injury severity score and revised trauma score.

Trauma Score

Numerical grading system that combines the Glasgow Coma Scale and measurements of cardiopulmonary function as a gauge of severity of injury and as a predictor of survival after blunt trauma to the head. Each parameter is given a number (high for normal and low for impaired or absent function). Severity of injury is estimated by summing the numbers. The lowest score is 1, the highest 16. SEE: table.
