Epidemiology of pediatric trauma: importance of population-based statistics.

To determine the validity of using hospital-based pediatric trauma registry data to draw specific inferences with regard to regional pediatric trauma system design, we compared statistical data on the incidence and mortality of pediatric and adult injuries and burns calculated by the New York State Department of Health, based on legally mandated reports of injury deaths and hospital discharges for 1989. During this year, some 488 children, aged 0 to 14 years, died as a result of injuries, a rate of 13.8 per 100,000 annually, of whom 408 (11.6/100,000) died as a result of traumatic injuries or burns, a population-based rate 20% of that observed in adults. During the same period, 16,402 children were hospitalized for treatment of traumatic injuries and burns, a rate of 465 per 100,000 annually, a population-based rate 56% of that observed in adults; and of this number, some 90 children died, yielding an in-hospital mortality "rate" (ie, case fatality ratio) of 0.55%, and a population-based rate of 2.6 per 100,000 annually. Thus, 9.0 of the 11.6 per 100,000 children who died in New York State in 1989 as a result of traumatic injuries and burns were not admitted to the hospital and, therefore, were unknown to the statewide hospital reporting system.(ABSTRACT TRUNCATED AT 250 WORDS)
