Utilization of the Neonatal Intensive Care Unit (NICU) varies widely in the United States. Over recent decades, there has been a growth in NICUs, that varies by region, and has not been correlated to changes in demand or illness severity. Unnecessary NICU admissions are costly, stressful to families, may increase the risk of hospital acquired morbidities, and decrease breast feeding. Most of the variation in NICU utilization is based on the care of late preterm, early term, and term babies and is related to hospital level factors, including financial incentives, driving utilization. Improvement strategies to reduce variation include regionalization of care, certificate of need legislation, improving discharge processes, and caring for babies with some conditions such as Neonatal Opioid Withdrawal Syndrome or those with risk factors for sepsis outside of the NICU.
