Drivers of Hospital Length of Stay in Medicaid and Commercially Insured Mother-Infant Pairs With a Diagnosis of Neonatal Abstinence Syndrome.

Background: The occurrence of neonatal abstinence syndrome (NAS) mirrors the growing opioid epidemic in the United States. As Medicaid covers a majority of cases, the commercially insured population has largely been ignored for NAS risk.

Objective: The objective of this study was to examine Medicaid and commercially insured mother-infant pairs to determine demographic and clinical characteristics associated with NAS length of stay (LOS).
