Lynch A1 - AB - OBJECTIVE:  This study aimed to evaluate the association between number of prenatal care visits and adverse perinatal outcome among pregnant individuals with opioid use disorder (OUD). STUDY DESIGN:  This is a retrospective cohort of singleton, nonanomalous pregnancies complicated by OUD that delivered from January 2015 to July 2020 at our academic medical center. Primary outcome was the presence of composite adverse perinatal outcome, defined as one or more of the following: stillbirth, placental abruption, perinatal death, neonatal respiratory distress syndrome, need for morphine treatment, and hyperbilirubinemia. Logistic and linear regression estimated the association between the number of prenatal care visits and the presence of adverse perinatal outcome. A Mann-Whitney U test evaluated the association between number of prenatal care visits and length of hospital stay for the neonate. RESULTS:  A total of 185 patients were identified, of which 35 neonates required morphine treatment for neonatal opioid withdrawal syndrome. During pregnancy, most individuals were treated with buprenorphine 107 (57.8%), whereas 64 (34.6%) received methadone, 13 (7.0%) received no treatment, and 1 (0.5%) received naltrexone. The median number of prenatal care visits was 8 (interquartile range: 4-10). With each additional visit per 10 weeks of gestational age, the risk of adverse perinatal outcome decreased by 38% (95% confidence interval [CI]: 0.451-0.854). The need for neonatal intensive care and hyperbilirubinemia also significantly decreased with additional prenatal visits. Neonatal hospital stay decreased by a median of 2 days (95% CI: 1-4) for individuals who received more than the median of eight prenatal care visits. CONCLUSION:  Pregnant individuals with OUD who attend fewer prenatal care visits experience more adverse perinatal outcome. Future research should focus on barriers to prenatal care and interventions to improve access in this high-risk population. KEY POINTS: · Use of prenatal care affects newborn outcomes.. · More prenatal care shortens neonatal hospital stay.. · Prenatal care reduces certain adverse outcomes..
