In the past few years, an emerging body of research has begun to document potential spillover effects of the ongoing opioid crisis on child welfare. This webinar will discuss recently published research in the Journal of Pediatrics showing that state implementation of PDMPs has been associated with reductions in child maltreatment prevalence at the population level. The webinar will also describe broader trends in substance-use related child welfare involvement—including prenatal substance use and foster care—as well as discussing policy implications and areas for future evaluation research.
