This is a phase 4, open-label, feasibility study of extended release naltrexone (Vivitrol, Alkermes Pharmaceutical) and case management for treatment of alcohol use disorders in the ED.

Excess alcohol use is a major cause of morbidity and mortality and contributes to a large number of emergency department (ED) visits. The rate of alcohol-related ED visits is increasing, and there is evidence that this increase may be driven by a subset of patients who frequently visit the ED due to an underlying alcohol use disorder (AUD). The proposed study will assess the feasibility of implementing a multimodal treatment for AUD in the emergency department for 25 patients with AUD. The rationale for including each component of the multimodal treatment is outlined below.

Pharmacotherapy is recommended as the standard of care for alcohol use disorders. Of the four drugs approved by the FDA for treatment of alcohol use disorder, extended release naltrexone has been found to be superior at reducing healthcare utilization, increasing detoxification facility use, and reducing total cost. Fewer than 1 in 4 patients with AUD currently receives treatment with an FDA approved agent and use of these drugs in EDs is virtually non-existent.

ED patients with alcohol use disorders frequently suffer from multiple medical, mental health, and social problems that influence their health. Providing such patients with case management services has shown promise in improving health related outcomes while curbing ED utilization and healthcare costs.

Regardless of comorbidity, limited access to substance use and mental health services is a significant barrier to receiving treatment, and large disparities exist in access based on income level. Facilitated referrals, where a healthcare worker communicates with the patient and service providers and assists the patient with obtaining follow up, have been used effectively to improve access to specialty care after ED discharge. Case managers are familiar with community treatment resources and are well versed in providing facilitated referrals.

The primary hypothesis is that implementing this multimodal treatment will be feasible in an ED setting and will reduce alcohol use. Feasibility measures (recruitment, retention, continuation of treatment after the trial) are the primary outcomes. The intent of the intervention is to change drinking behavior in a way that benefits participants' health and quality of life. As such, we will conduct a limited efficacy assessment. Treatment efficacy will be assessed by comparing alcohol consumption, quality of life, and life consequences related to alcohol use before and after the intervention.

The primary efficacy outcome is change in total alcohol consumption measured by a 2 week timeline follow back. Change from baseline will be assessed after the 3 month intervention period, and at the conclusion of the study follow up period for all outcomes.
