Families affected by substance misuse are at increased risk for child maltreatment and child welfare system involvement. The Enhancing Permanency in Children and Families (EPIC) program uses four evidence-based and informed multi-system practices to promote safety and permanency outcomes for children involved with the child welfare system due to parental substance misuse: 1) Peer Recovery Support (PRS), 2) Family Treatment Drug Court (FTDC), 3) Medications for Opioid Use Disorder (MOUD) and 4) Nurturing Parent Program (NPP) relational skill-building. The purpose of the current study was to identify barriers, facilitators, and lessons learned in the implementation of and client engagement with the main components of EPIC.
