Neonatal Abstinence Syndrome in North Carolina: Incidence and Characteristics among Infants and Mothers.

The objective of this study was to determine the incidence of NAS, as well as infant and maternal characteristics associated with NAS in North Carolina (NC). This retrospective, cross-sectional, observational study used the State Inpatient Database (SID) to compare the incidence rates of NAS for NC for the year 2016 to historical data (years 2000 to 2013).
