ObjectivesTraumatic brain injury is a leading cause of death in children. On the basis of evidence of better outcomes, the American College of Surgery Committee on Trauma recommends that children with severe traumatic brain injury receive care at high-level trauma centers. We assessed rates of adherence to these recommendations and factors associated with adherence.MethodsWe studied population and hospital discharge data from 2001 from all of the health care referral regions (n = 68) in 6 US states (Florida, Massachusetts, New Jersey, New York, Texas, and Virginia). We identified children with severe traumatic brain injury by using International Classification of Diseases, Ninth Revision, Clinical Modification, codes and American College of Surgery Committee on Trauma criteria. We defined "high-level centers" as either level I or pediatric trauma centers. We considered an area to be well regionalized if >or=90% of severe traumatic brain injury hospitalizations were in high-level centers. We also explored how use of level II trauma centers affected rates of care at high-level centers.ResultsOf 2117 admissions for severe pediatric traumatic brain injury, 67.3% were in high-level centers, and 87.3% were in either high-level or level II centers. Among states, 56.4% to 93.6% of severe traumatic brain injury admissions were in high-level centers. Only 2 states, Massachusetts and Virginia, were well regionalized. Across health care referral regions, 0% to 100% of severe traumatic brain injury admissions were in high-level centers, and only 19.1% of health care referral regions were well regionalized. Only a weak relationship existed between the distance to the nearest high-level center and regionalization. The age of statewide trauma systems had no relationship to the extent of regionalization.ConclusionsDespite evidence for improved outcomes of severely injured children admitted to high-level trauma centers, we found that almost one third of the children with severe traumatic brain injury failed to receive care in such centers. Only 2 of 6 states and less than one fifth of 68 health care referral regions were well regionalized. This study highlights problems with current pediatric trauma care that can serve as a basis for additional research and health care policy.
