A Comparison of Two Statewide Datasets to Understand Population Prevalence of Substance Use in Pregnancy: Findings and Considerations for Policy Research

Mental health conditions including substance use disorder are the leading cause of pregnancy-related deaths in the U.S. Unfortunately, fears of child protective services’ involvement interfere with maternal self-disclosure of substance use in pregnancy. Seeking to identify more mothers with substance use disorder in pregnancy or at delivery, and responsive to changes to the federal Child Abuse Prevention and Treatment Act (CAPTA), Connecticut requires hospital personnel to submit a deidentified notification to CPS for all newborns with prenatal substance exposure. However, it is unknown whether this approach aligns with maternal self-report on substance use. For the present study, we compared population parameters derived from CAPTA notifications submitted between March-December 2019 with parameters derived from self-report data on substance use in pregnancy from mothers who gave birth during the same timeframe. Results revealed that three times as many mothers self-reported any alcohol or drug use in pregnancy compared to the rate measured with CAPTA notifications. Compared to mothers who self-reported drug use in the third trimester, CAPTA notifications were made for statistically similar rates of Black mothers but half the self-reported rate of White and Hispanic mothers. This disparity reflects that CAPTA notifications were made for twice as many Black mothers as White or Hispanic. Although CAPTA notifications are not punitive in nature, this disparity reveals that the public health aims of this policy are not yet achieved. Accurate and equitable identification of infants with prenatal substance exposure and their mothers, coupled with non-stigmatized, non-punitive intervention is central to any public health response.The current study relies on 2019 data from Connecticut to understand accuracy and equity in identification of these infants by comparing hospital-based notifications to self-report substance use in pregnancy. We found that hospital approaches to detecting prenatal substance exposure identified twice as many Black mothers as White or Hispanic mothers. Compared to self-reported substance use in pregnancy, which detected equivalent rates of substance use across race groups, White and Hispanic mothers’ substance use in pregnancy was under-identified in hospital settings.
