Abstract
BACKGROUND: Alcohol use disorder (AUD) is ubiquitous and its sequelae contribute to high levels of healthcare utilization, yet AUD remains undertreated. The ED encounter represents a missed opportunity to initiate medication assisted treatment (MAT) for patients with AUD. The aims of this study are to identify barriers and facilitators to the treatment of AUD in the ED, and to design interventions to address identified barriers. METHODS: Using an implementation science approach based on the Behavior Change Wheel framework, we conducted qualitative interviews with staff to interrogate their perspectives on ED initiation of AUD treatment. Subjects included physicians, nurses, nurse practitioners, clinical social workers, and pharmacists. Interviews were thematically coded using both inductive and deductive approaches and constant comparative analysis. Themes were further categorized as relating to providers' capabilities, opportunities, or motivations. Barriers were then mapped to corresponding intervention functions. RESULTS: Facilitators at our institution included time allotted for continuing education, the availability of clinical social workers, and favorable opinions of MAT based on previous experiences implementing buprenorphine for opioid use disorder. Capability barriers included limited familiarity with naltrexone and difficulty determining which patients are candidates for therapy. Opportunity barriers included the limited supply of naltrexone and a lack of clarity as to who should introduce naltrexone and assess readiness for change. Motivation barriers included a sense of futility in treating patients with AUD and stigmas associated with alcohol use. Evidence-based interventions included multi-modal provider education, a standardized treatment algorithm and order set, selection of clinical champions, and clarification of roles among providers on the team. CONCLUSIONS: A large evidence-practice gap exists for the treatment of AUD with Naltrexone, and the ED visit is a missed opportunity for intervention. ED providers are optimistic about implementing AUD treatment in the ED but described many barriers, especially related to knowledge, clarification of roles, and stigma associated with AUD. Applying a formal implementation science approach guided by the Behavior Change Wheel allowed us to transform qualitative interview data into evidence-based interventions for the implementation of an ED-based program for the treatment of AUD.
