Relevance: Pediatric ED visits for MH issues are increasing, but the current system of managing these patients is not optimal. More information is needed to accelerate change and to efficiently invest in improving services available to MH patients. Specifically, information is needed on which MH populations need to be targeted, and on simple, reproducible interventions which improve connection with community resources. The proposed study will collect vital information needed to develop programs that improve outcomes and reduce ED revisits in pediatric patients visiting the EDs at CH with primary MH concerns, and will set the stage for future work focused on improving core and outcomes for MH youth.
