Outcome Measures
Primary Outcomes (1)
Recruitment rate
The investigators will assess recruitment rate for IM naltrexone and oral naltrexone o Recruitment is defined as (\[number of participants enrolled / number of participants enrolled approached\] / 12 months)
12 months
Secondary Outcomes (3)
II. Acceptability and Feasibility Measures
prior to study implementation and after 50% enrollment is completed, approximately 6 months from study start date
III. Comparative Effectiveness: Combined all-cause 30-day readmission rate + all cause 30-day emergency department encounter rate.
30 days from time of last person enrolled in study
IV. Comparative Effectiveness: 90-day addiction treatment encounter rate for participants randomized to IM vs. oral naltrexone
90 days from time of last person enrolled in study
Study Arms (2)
Oral naltrexone
ACTIVE COMPARATORpatients will receive a 30 day supply of oral naltrexone 50 mg daily at hospital discharge. This medication was FDA approved in 1984 for the treatment of alcohol use disorder
injectable naltrexone
EXPERIMENTALpatient will receive 360 mg injection of naltrexone prior to hospital discharge
Interventions
360 mg dose to be given prior to hospital discharge
50 mg tab dispense 30 day supply to be given at hospital discharge
Eligibility Criteria
You may qualify if:
- Participants will include hospitalized adults, aged 18 to 65 years old, who receive care from the ACS during their hospitalization and who meet DSM - 5 criteria for alcohol use disorder.
You may not qualify if:
- Naltrexone is contraindicated in acute hepatitis or liver failure and its use in patients with active liver disease must be carefully considered in light of the potential for hepatotoxic effects.23 It is also contraindicated in patients taking opioids for pain due to its antagonism at the opioid receptor.23 The investigators will exclude people who meet the following criteria:
- Liver function test (AST/ALT) more than five times the upper limit of normal
- Decompensated liver failure defined as use of lactulose for prevention of hepatic encephalopathy, ascites, use of spironolactone and/or lasix for ascites, presence of hepatic encephalopathy, International Normalized Ratio (INR) \>2, or thrombocytopenia in the setting of known liver disease
- Renal failure, defined as a glomerular filtration rate of \<30 ml/min
- On opioids for acute or chronic pain at time of study enrollment
- Pregnancy, IM naltrexone is not FDA approved in pregnancy
