Future research should focus on the relationship between diagnostic groups (eg, mothers with long-term methadone use) and neonatal outcomes, including but not limited to NAS. Different outcomes—with quite different costs—may occur for neonates of women who are untreated or misusing opioids vs those maintained on opioid agonists or medicated for pain. While many of the clinical conditions in Table 1 of the article may occur in infants born to methadone-stabilized women, their frequency in infants born to methadone-stabilized women is lower2 than the frequency reported for all infants born with NAS.
