The significance of patient appearance in predicting severity of injury.

The observations of pallor, sweating, agitation and restlessness, at the time of an injured patient's admission to the resuscitation room, were compared with other more complex indices of injury severity and the ability of each observation to predict mortality was observed. The number of positive observations was significantly related to the Revised Trauma Score and the Injury Severity Score, and pallor was significantly related to mortality. The observation that an injured patient is pale is an important index of severity.
