    Abstract:
    OBJECTIVES: To estimate the effect of early childhood abuse (ie, inflicted injury) on medical costs of head trauma. METHODS: Abstracts of patient records were drawn from the annual 1993-2000 Colorado state-mandated hospital discharge database maintained by the Colorado Hospital Association. The 2 dependent variables were total charges (TC) and length of stay. Our key independent variable was the nature of injury, ie, inflicted or unintentional; other independent variables were age, severity level, death, and trauma designation of the hospital. Comparisons of variables between patients with inflicted and unintentional head trauma were performed using Student's t tests or chi2 statistics. Ordinary least squares regression was used to estimate the marginal and total effects of inflicted injury on TC and LOS. RESULTS: Of the 1097 head trauma patients <3 years old, 814 had unintentional and 283 had inflicted head trauma. Head trauma was defined using the Centers for Disease Control definition of traumatic brain injury. Patients with inflicted injuries were younger and had a higher average severity level and overall mortality rate than did patients with unintentional head trauma. The regression models showed that, controlling for age and severity, patients with inflicted head trauma stayed in the hospital 52% longer (2 days), and had a mean total bill 89% higher (4232 dollars more) than did patients with unintentional head trauma. CONCLUSIONS: The findings from multivariate models of TC and length of stay corroborate the simpler univariate findings of earlier studies. By focusing on the impact of those cases of child abuse that lead to a specific, severe clinical entity (traumatic brain injury), we isolated a significant economic impact of abuse on health care expenditures for injury.
