RESULTS
Traumatic Brain Injury
There were 5,272 children with head injuries registered during the study period. There were 477 severe TBIs. In Figure 1
head injury registrations are plotted by severity and year.
Over the course of the study period, registrations of severe
and moderate head injuries were stable, but compared to more severe injuries, registrations of mild head injuries increased is an apparent breakpoint between 2006 and 2007 coinciding with the beginning of NAIDHC’s participation in the trauma system. Registrations of mild TBIs increased as a fraction of
all registrations from 1,737 of 2,038 (85.2 percent) before the incorporation of NAIDHC into the DTS to 2,894 of 3,230 (89.6 degrees of TBI between the period of NAIDHC’s Level 3 and mild TBI constituted 90 percent of registrations.

Severity of TBI is presented by age group in Table 1. After trend in severity of injury with increasing or decreasing age.
The mortality rate for severe pediatric TBI in Delaware dropped from 27 percent before incorporation of NAIDHC into the DTS to 19.5 percent in later years (Fisher’s exact test, p = 0.0624).
Substantive Admissions
Based on the criteria adopted for this study, 2,890 registrations were substantive, and 2,378 were non-substantive. In
Figure 2 substantive and non-substantive registrations are plotted by year. Both substantive (Pearson R = 0.69, p =
