Primary objective: To examine the hospitalization costs and discharge outcomes of US children with TBI and to evaluate a severity measure, the predictive mortality likelihood level.
Research design: Data from the 2006 Healthcare Cost and Utilization Project Kids' Inpatient Database (KID) were used to report the national estimates and characteristics of TBI-associated hospitalizations among US children < or =20 years of age. The percentage of children with TBI caused by motor vehicle crashes (MVC) and falls was calculated according to the predictive mortality likelihood levels (PMLL), death in hospital and discharge into long-term rehabilitation facilities. Associations with the PMLL, discharge outcomes and average hospital charges were examined.
Results: In 2006, there were an estimated 58 900 TBI-associated hospitalizations among US children, accounting for $2.56 billion in hospital charges. MVCs caused 38.9% and falls caused 21.2% of TBI hospitalizations. The PMLL was strongly associated with TBI type, length of hospital stay, hospital charges and discharge disposition. About 4% of children with fall or MVC related TBIs died in hospital and 9% were discharged into long-term facilities.
Conclusion: The PMLL may provide a useful tool to assess characteristics and treatment outcomes of hospitalized TBI children, but more research is still needed.
