This Statistical Brief presents data from the Healthcare Cost and Utilization Project (HCUP) on hospital stays related to child maltreatment in the U.S. in 2005. Child maltreatment includes both acts of abuse and acts of neglect perpetrated by a parent or caregiver. Utilization and resource use for pediatric hospitalizations related to maltreatment are compared to stays unrelated to maltreatment. Patient and payer characteristics of child maltreatment-related hospitalizations are also described. Finally, the most common diagnoses associated with maltreatment-related pediatric hospitalizations are identified. All differences between estimates noted in the text are statistically significant at the 0.05 level or better.
