Summary

The specific aims of this pragmatic randomized controlled trial are to compare initiating injectable extended release naltrexone (XR-NTX) or oral naltrexone (PO-NTX) at the time of discharge from a medical hospitalization for patients with alcohol use disorder (AUD) on: 1) alcohol consumption and consequences, and 2) acute healthcare utilization (including hospital readmission and emergency visits) and cost-effectiveness. In exploratory analyses, the investigators will assess moderators of medication effects including demographic, behavioral, and genetic factors.

Clinical Details

Official title: Oral v. Injection Naltrexone in Hospital Comparative Effectiveness for Alcoholism

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: percent heavy drinking days (%HDDs) over the past 30 days assessed at 3 month follow-up by the Timeline Follow-Back

Secondary outcome: Acute care hospital utilization

Detailed description: Hospitalization for medical illness is a unique and missed opportunity for intervention for alcohol use disorders (AUDs). Referrals can help link patients from hospitals to alcohol treatment. But most patients return to heavy drinking after hospital discharge and do not follow-up with alcohol treatment, risking hospital readmission. Pharmacotherapy has efficacy for alcohol dependence, but adherence to these medications is poor. Furthermore, these medications are rarely prescribed in general medical settings, during or after hospitalization. Beginning treatment for alcohol dependence during a hospitalization for medical illness could broaden the reach of effective treatment and is likely to be more effective than delaying treatment until a specialist visit or treatment program entry. Hospital discharge is a time of both risk (i. e., for drinking and non-adherence to medical care) and opportunity (i. e., to begin alcohol treatment and complete medical treatments). Interventions that work quickly and improve adherence could improve medical and alcohol-related outcomes. Oral naltrexone (PO-NTX), and the more-costly-per-dose long-acting injectable extended release naltrexone (XR-NTX) are Food and Drug Administration (FDA)-approved efficacious treatments for alcohol dependence. The XR-NTX half-life is 5-10 days and is dosed monthly, whereas the PO-NTX half-life is 13 hours and is dosed daily. The longer half-life of XR-NTX translates into patients receiving effective pharmacotherapy for a longer time without having to adhere to a daily dose. Thus, although more costly per dose, greater effectiveness could mean overall reduced costs of care (including alcohol-related health consequences and healthcare utilization). Despite potential differences in costs and patient preferences, PO-NTX and XR-NTX have not been directly compared in a randomized controlled trial (RCT), they have not been studied as treatments at medical hospital discharge, and their effectiveness in real world practice settings compared with standard care is unknown. This trial is significant because it will address the clinically relevant comparative effectiveness question and lead to greater adoption of the most effective and cost-effective approach for treating AUD with pharmacotherapy in general hospitals.
