ED Initiated Oral Naltrexone for AUD

August 7, 2025 updated by: Ethan Cowan, Icahn School of Medicine at Mount Sinai

Emergency Department Initiated Oral Naltrexone for Patients With Moderate to Severe Alcohol Use Disorder: A Pilot Feasibility Study

This study will recruit Emergency Department (ED) patients with moderate to severe alcohol use disorder (AUD) who are interested in initiating medication assisted treatment (MAT). The study is split into two phases. The first phase (N=10) will use implementation science strategies to strengthen existing non-targeted ED based AUD screening program and optimize feasibility, acceptability, and linkage pathways. The second phase (N=20) will incorporate lessons learned from phase 1 to initiate ED patients on MAT for AUD in the form of oral naltrexone. The primary outcome for both phase 1 and phase 2 is engagement in comprehensive addiction treatment at 14 and 30 days post enrollment.

Detailed Description

Overview

The study will be comprised of two components outlined below:

  1. Site Implementation Component

    In this component implementation science strategies will be used to strengthen existing non-targeted ED based AUD screening program and optimize feasibility, acceptability and linkage pathways. Three specific aims are to, 1) optimize registered nurse (RN) driven non-targeted alcohol use screening supplemented with secondary screening using DSM-5 criteria for AUD and an SBIRT (screening, brief intervention and referral to treatment) intervention administered by trained staff. 2) During a 3-month period, use continuous quality improvement methods to decrease the time for completion of AUD screening to an interval that is acceptable to ED patients and ED providers and 3) Assess willingness to initiate oral naltrexone among ED patients with moderate to severe AUD. Ten (10) patients will be enrolled in phase 1.

  2. Oral Naltrexone Feasibility Component

In this component the study team aims to assess the feasibility of initiating treatment in ED patients with moderate to severe AUD on oral naltrexone, an evidence based and accepted standard of care treatment for AUD. Specifically, 1) over an 8-month period the study team aims to identify 20 patients with moderate to severe AUD eligible and interested in immediate initiation of oral naltrexone. Consenting patients will be receive a standard SBIRT intervention and be provided with immediate oral naltrexone initiation in the ED with a 14-day starter pack at the time of ED discharge. All participants will receive facilitated linkage to comprehensive out-patient care. 2) The study team aims will evaluate the impact of immediate ED initiated oral naltrexone with the primary outcome being engagement in comprehensive addiction care at 14 and 30 days post enrollment. Secondary outcomes include medication adherence, changes in daily alcohol consumption, number of heavy drinking days, hospital admissions and ED utilization, transition to long-acting injectable naltrexone and alcohol craving. 3) Lastly, the study team will collect data on recruitment and attrition rates, as well as means and standard deviations for key measures that will be needed to plan a definitive randomized controlled trial of ED-initiated oral naltrexone.

Health Services Utilization Survey
Time Frame: up to 30-days
Participants indicated the number of inpatient admissions, outpatient visits and emergency department visits over the preceding 7-days at baseline up to 30-days. Comparison of total reported admissions or visits were made using the Friedman test. No admissions or visits counted as a 0 for comparing across timepoints. If no response was provided at any of the three time points, the participant data was not used in the comparison.

Time Frame: Day 30
Number of unhealthy days using the HRQoL. The HRQoL assesses core health days and activity limitations. Self-reported general health was collected on a 5-item scale ranging from: excellent, very good, good, fair, and poor. An unhealthy days score was obtained by summing the number of physically unhealthy and mentally unhealthy days. The minimum score is 0 and the maximum score is 30 unhealthy days, even if the number of unhealthy days totals more than 30. If no response was provided at the time points under comparison, the participant data was not used in the comparison.
Day 30
The Patient Rated Inventory of Side Effects (PRISE) Survey
Time Frame: Day 30
Medication side effects of oral naltrexone measured using PRISE survey - is a patient self-report measure used to identify and evaluate the tolerability of side effect symptom. This scale is a 7-item assessment of the side effects in the following symptom areas; gastrointestinal, heart, skin, nervous system, eyes/ears, genital/urinary, sleep, sexual functioning, and other. Each domain has multiple symptoms and for each domain the patient rates whether these symptoms are tolerable or distressing. Higher score represents more side-effects. What is reported below are the number of participants reporting side effects for each symptom.
Day 30

Time Frame: Baseline
Three elements of satisfaction were assessed: 1) convenience of screening, 2) difficulty of screening and 3) satisfaction with screening. Each question could be scored on scale of 0-6. For convenience of screening, lower numbers indicated more convenience. For difficulty of screening, lower numbers represent less difficulty. For satisfaction, higher numbers represent greater satisfaction.
