Trauma Center Utilization for Children 1998-2004: Trends and Areas for Further Analysis
Background: While trauma systems improve the outcome of injury in children, there is a paucity of information regarding trauma regionalization system function amid dramatic changes in the financial structure of health care.
Objective: To describe the distribution of acute hospitalization of children with severe trauma by level of hospital trauma care designation in California.
Methods: Retrospective observational study of a population-based cohort from 1998 to 2004. The California Office of Statewide Health Planning and Development (OSHPD) patient Discharge Data Set 1998-2004 was used. Patients were included if: age 0-19 years, trauma International Classification of Diseases, 9th Edition (ICD-9) diagnostic codes, and e-codes (n = 127,841). Differential rates of hospitalization in trauma-designated hospitals vs. non-trauma-designated hospitals were calculated for death and injury severity score. Injury severity scores (ISSs) were calculated from ICD-9 codes. Primary outcomes were hospitalization in a trauma center and death.
Results: From 1998 to 2004, 55%-60% of children 0-14 years and 55%-70% of children 15-19 years with trauma requiring hospitalization were discharged from trauma-designated hospitals. Children with severe injury were consistently hospitalized in trauma-designated hospitals (70%-78%) at a rate higher than children with moderate (60%-70%) and mild (50%-60%) injury. Trends for hospitalization in trauma-designated hospitals increased over the time span of the study (p 0.05). Approximately 20% of hospitalized children who died (I = 1,426) died 2 or more days after injury in non-trauma-designated hospitals.
Conclusions: A majority of children with trauma were cared for in trauma-designated hospitals over the study period. However, 20% of children with severe injuries and 20% of pediatric deaths greater than 2 days after injury were cared for in non-trauma-designated hospitals. Further investigation is warranted in order to enhance clinical protocols and policies that ensure access to appropriate regional trauma care for all children in need.
