Abstract
OBJECTIVES: Given the paucity of data on resource utilization among children with encephalitis, the objective of this study was to describe the epidemiology and evaluate resource utilization and discharge data of children with encephalitis admitted to US hospitals from 2004 to 2013. METHODS: We conducted a retrospective cohort study utilizing the Pediatric Health Information System database of children aged 0 to 18 years with the International Classification of Diseases, Ninth Revision codes for encephalitis from 2004 to 2013. Only the initial admissions were included, and the age group analyzed was 0 to 18 years. RESULTS: Among 7298 children with encephalitis, 2933 (40%) were admitted to a pediatric intensive care unit. The median age was nine years, the overall median length of stay was 16 days, and children requiring critical care had a median length of stay of 25 days. Children in the pediatric intensive care unit were more likely to have seizures (P <0.001) and head magnetic resonance imaging (P <0.001) than children on the floor. Similarly, children requiring critical care were more likely to have a broad diagnostic evaluation sent including cerebrospinal fluid cultures, blood bacterial and fungal cultures, western equine encephalitis antibody, St. Louis equine encephalitis antibody, varicella-zoster serology, human immunodeficiency virus 1 antibody, human immunodeficiency virus DNA polymerase chain reaction, acid-fast stain, and Lyme disease serology. Seventeen percent of children were treated with intravenous immunoglobulin, and 4% underwent plasmapheresis. There was a trend of increasing use of intravenous immunoglobulin and plasmapheresis in children with encephalitis over the study period. A total of 5944 (81%) children were discharged home, and the mortality in this cohort was 3% (230). The mean charges for hospitalization for a child with encephalitis was $64,604 and for those requiring critical care was $260,012. CONCLUSIONS: Encephalitis is a significant cause of morbidity and mortality in children. Children with encephalitis admitted to the pediatric intensive care unit are more likely to have seizures and to undergo a more extensive evaluation to determine the cause of encephalitis. Use of plasmapheresis and intravenous immunoglobulin is on the rise in hospitalized children. Prospective studies are necessary to better understand treatment and intervention strategies for children with encephalitis and their impact on outcomes.
