Abstract
Eighty-six traumatically brain-injured children aged 6 to 15 years who were consecutively admitted to a pediatric Level I trauma center were recruited for participation in the study. A comprehensive battery of behavioral, cognitive, communicative, social, motoric, and neurological tests was administered to the children from 12 to 36 months postinjury. The performance of three severity indices, the Glasgow Coma Scale (GCS), the ASCOT probability of survival, and the head injury component of the Anatomic Profile, was compared with respect to their association with long-term outcomes in five neurological domains, as assessed by linear regression models. The ASCOT probability of survival was correlated to test scores in all five domains. The GCS and the head injury component of the Anatomic Profile were each correlated to outcome in only one domain. The ASCOT probability of survival, which includes coded variables for the GCS, systolic blood pressure, and respiratory rates on admission, as well as a measure of multisystem anatomic injury, was the most sensitive indicator of head injury severity and was associated with outcomes beyond survival and death in this population. Probability of survival is a promising brain injury severity index that may be useful in efforts to assess new medical and rehabilitative therapies for children with traumatic brain injury.
