Trauma triage: vehicle damage as an estimate of injury severity.
Field triage of injured patients has the objective of rapid identification of that 5-10% with injuries serious enough to pose a risk to life. The process requires not only the identification of patients with abnormal physiology, but also those whose physiology is normal despite the fact that significant anatomic injury may exist. This paper defines relationships by which vehicle damage information available at the accident may augment the physiologic measures used for triage decisions. Vehicle velocity changes of 20 m.p.h. or more in direct frontal collisions, 22 m.p.h. or more in offset frontal collisions, and 15 m.p.h. or more in side impacts captured 90% of the patients with Injury Severity Scores of 16 or greater. The amount of vehicle damage observed with these velocity changes was found to be 20 inches of crush in direct frontal collisions, 28 inches of crush in offset frontal collisions, and 15 inches of damage in side impacts. Incorporating these findings into triage of trauma patients who exhibit normal vital signs at the accident scene may provide a more structured basis for field triage.
