Wolf ER, Tong ST, Sabo RT, et al. - As adult opioid use and neonatal abstinence syndrome (NAS; a drug withdrawal syndrome experienced by newborns whose mothers have taken opioids or other substances during pregnancy) are increasing public health problems in the United States, researchers discovered how opioid use disorder treatment access impacts the connection between adult opioid use and NAS. Using 36 states with available Healthcare Cost and Utilization Project State Inpatient Databases in 2014, researchers carried out a cross-sectional state-level ecologic study. Findings suggested a positive association of unmet need for substance use disorder treatment with NAS. For states with higher levels of access to opioid use disorder treatment, the association between adult illicit drug use/dependence and NAS has been dampened. Future studies using community or individual-level data may be better able to address whether NAS occurrence can be minimized by incorporating opioid use disorder treatment programs or buprenorphine-waivered physicians. Since NAS results in significant infant morbidity and healthcare costs, consideration should be given to the impact of NAS when considering public health measures that would improve access to treatment for opioid use disorder.
