Pre-natal and post-natal screening and testing in neonatal abstinence syndrome.

The way we enact screening for substance use during pregnancy within our healthcare systems can work by decreasing stigma, promoting engagement, and supporting people with reaching the end of their pregnancy in a manner where the newborn can be well supported. The way we enact biochemical specimen toxicology testing for substance use during pregnancy and in newborns contributes to increased stigma, disengagement from care, and potential continuation of uncontrolled substance use up until delivery such that the newborn may not be able to be well supported in the family environment. These effects are inequitably distributed, leading to worse outcomes for families of color and families living in poverty. Serial screening with a validated questionnaire starting at the first prenatal visit and continuing through the delivery hospitalization should occur and be followed up with service connections and substance use disorder diagnosis and treatment. Newborn toxicology testing as a diagnostic tool for risk of withdrawal or the etiology of potential withdrawal symptoms represents a failure in the effectiveness of compassionate communication by healthcare providers with the birthing person. Given the current level of evidence of clinical utility and the inequitable consequences specific to these tests, they are rarely needed.
