Pediatric Brain Injuries: The Nature, Clinical Course, and Early Outcomes in a Defined United States' Population

Abstract

Acute brain injury is the cause of approximately 100,000 pediatric hospital admissions per year in the United States. This report examines the nature of the brain injury, clinical diagnosis, hospital course, and discharge outcome of all pediatric cases in the population of San Diego County, California, for 1981 (N = 709). Brain-injured children were identified from hospital records, death certificates, and coroners' records. Severity of injury was determined using the Abbreviated Injury Scale and the Glasgow Coma Scale. Three percent of brain-injured children died at the accident site; an additional 3% died in the hospital. All in-hospital deaths occurred among the 5% of children with Glascow Coma Scale scores of 8 or less, and in this group the case fatality rate was 59%. Fractures of the skull, present in 23% of cases, seemed to be associated with excess mortality even after type of lesion was considered. Type of lesion, but not presence or absence of a skull fracture, had some predictive power for disability among survivors. Concussion was the most frequent diagnosis. Mildly brain-injured children accounted for 93% of all cases and about 90% of all hospital days.
