Peer support for patients with opioid use disorder in the emergency department: A narrative review

Abstract

Faced with a growing opioid overdose crisis, emergency departments (EDs) are increasingly hiring peers-people with lived experiences of addiction and recovery-to work with patients in the ED who have opioid use disorders (OUDs) or who have experienced an opioid overdose. Despite a clear need for more support for patients with OUD and rapid expansion in grant funding for peer programs, there are limited data on how these programs affect clinical outcomes and how they are best implemented within the ED. In this narrative review, we synthesize the existing evidence on how to develop and implement peer programs for OUD in the ED setting. We describe the key activities peers can undertake in the ED, outline requirements of the peer role and best practices for peer supervision and hiring, detail how ED administrators have built financial and political support for peer programs, and summarize the limited evidence on clinical and care linkage outcomes of peer programs. We highlight key resources that ED clinicians and administrators can use to develop peer programs and key areas where additional research is needed.
