Trends and Resource Utilization for Neonatal Jaundice Hospitalizations in the United States.

OBJECTIVES: To evaluate the trends in hospitalization for neonatal jaundice and its management with phototherapy and exchange transfusion in the United States from 2006 through 2016. METHODS: Repeated, cross-sectional analysis of the 2006 to 2016 editions of the Kids' Inpatient Database. All neonatal hospitalizations with an International Classification of Diseases, 9th or 10th Revision, Clinical Modification code for jaundice and admitted at age ≤28 days were included. The outcome measures were changes in the diagnosis of jaundice (expressed as a proportion) and its management over the years. RESULTS: Among 16 094 653 neonatal hospitalizations from 2006 to 2016, 20.5% were diagnosed with jaundice. While the incidence of jaundice remained stable over the years, 20.9% to 20.5% (P = .1), the proportion with jaundice who received phototherapy increased from 22.5% to 27.0% (P < .0001) between 2006 and 2016. There was no significant change in the exchange transfusion rate per year among neonatal hospitalizations with jaundice. CONCLUSIONS: While the proportion of newborns with jaundice remained stable between 2006 and 2016, the use of phototherapy significantly increased with no significant change in exchange transfusion rate. The impact of these changes on the prevention of acute bilirubin encephalopathy needs further examination in future studies.
