Implementation and analysis of a multifaceted intervention for alcohol use disorder from a single academic urban emergency department.

ABSTRACT

BACKGROUND: From 2006 to 2014, alcohol-related visits to the emergency department (ED) increased by 76% in the United States, highlighting the need for improved ED-driven interventions addressing alcohol use disorder (AUD). Naltrexone is an FDA-approved medication for AUD shown to decrease craving and self-administration of alcohol. While oral naltrexone and extended-release naltrexone have been long utilized in primary care and inpatient hospital settings, the use of naltrexone in the ED is limited. METHODS: This study implemented and analyzed a multifaceted intervention regarding ED naltrexone prescribing at a large safety net, academic, urban hospital. A baseline assessment of preintervention conditions and perspectives on naltrexone prescribing was conducted through a chart review and standardized interviews with ED providers, respectively. The interview results guided design of interventions that addressed identified barriers. These included provider education, prescribing aids, and zero-cost naltrexone tablets supplied by the ED pharmacy to patients upon discharge. RESULTS: Between September 1, 2019, and August 31, 2020, of 753 unique patients who had a primary diagnosis or chief complaint containing the word "alcohol," only five (0.66%) were prescribed naltrexone. ED providers identified lack of training regarding naltrexone, lack of a prescribing protocol, and limited patient and provider education materials as barriers to prescribing naltrexone. Following the intervention, among 278 eligible patients, 11 oral naltrexone prescriptions were written (3.96%) between April 13, 2021, and August 1, 2021. This represents a sixfold increase over the preintervention period. CONCLUSIONS: An intervention to increase ED oral naltrexone prescriptions for AUD was successfully implemented, addressing lack of provider education, lack of prescribing resources, and patient barriers to accessing prescribed medications. Longer-term follow-up is needed to assess the efficacy and sustainability of these interventions. Nevertheless, ED clinicians are well positioned to initiate naltrexone prescriptions for patients presenting with AUD.
