Hospitalizations of high-risk infants are among the most expensive in the United States, with many requiring surgery and months of intensive care. Healthcare costs and resource use associated with hospitalized infant opioid exposure are less well known. A retrospective cohort of high-risk infants aged <1 y admitted from 47 children's hospitals from 2010 to 2020 was identified from Pediatric Healthcare Information System. High-risk infants were identified by International Classification of Diseases 9/10 codes for congenital heart disease procedures, medical and surgical necrotizing enterocolitis, extremely low birth weight, very low birth weight, hypoxemic ischemic encephalopathy, extracorporeal membrane oxygenation, and gastrointestinal tract malformations. Healthcare resource utilization was estimated using standardized unit costs (SUCs). The impact of opioid use on SUC was examined using general linear models and an instrumental variable. Overall, 126,897 high-risk infants were identified. The cohort was majority White (57.1%), non-Hispanic (72.0%), and male (55.4%). Prematurity occurred in 26.4% and a majority underwent surgery (77.9%). Median SUC was $120,585 (interquartile range: $57,602-$276,562) per infant. On instrumental variable analysis, each day of opioid use was associated with an increase of $4406 in SUC. When adjusting for biologic sex, race, ethnicity, insurance type, diagnosis category, number of comorbidities, mechanical ventilation, and total parental nutrition use, each day of opioid use was associated with an increase of $2177 per infant. Prolonged opioid use is significantly associated with healthcare utilization and costs for high-risk infants, even when accounting for comorbidities, intensive care, ventilation, and total parental nutrition use. Future studies are needed to estimate the long-term complications and additional costs resulting from prolonged opioid exposures in high-risk infants. Copyright © 2024. Published by Elsevier Inc.
