Factors associated with closed head injury in a pediatric population.

The purpose of this study was to identify characteristic factors in children who sustained closed head injury (CHI) between birth and less than 15 years of age. A two-year retrospective audit of charts from a large metropolitan pediatric hospital with a trauma center yielded a sample of 138 charts that met the established criteria for inclusion in the study. Using a descriptive design, data were gathered on age, sex, race, cause of injury, severity of injury, season of accident, time of accident and length of hospital stay. Data analysis revealed that males were 1.5 times more likely to sustain CHI than females. Both sexes showed the highest incidence of CHI during the first year with a second less dramatic peak at around 6 years of age. Transportation-related causes accounted for 57.2% of the injuries with falls accounting for another 22.5%. Of the transportation-related injuries, 27.5% were associated with motor vehicle accidents. The lack of restraint use for subjects in the motor vehicle accident group was associated with 5 deaths as opposed to no deaths in subjects who were restrained. Over 70% of the injuries occurred in the time periods of 2:00-6:00 p.m. (31.9%) and 6:00-10:00 p.m. (40.7%). CHI occurred less frequently in the winter (13.8%) than any other season. Using the Glasgow Coma Scale scores, 56.5% of the injuries were categorized as mild, 17.4% were moderate and 26.1% were severe. There was an 8% mortality rate secondary to injury in the sample.
