A Neuropharmacological Model to Explain Buprenorphine Induction Challenges
We present data from clinical studies of buprenorphine induction and propose a neuropharmacologic working model, which posits that acute clinical success of buprenorphine induction (achieving a positive agonist-to-withdrawal balance) is a nonlinear outcome of the opioid balance at the time of initial buprenorphine dose and mu-opioid–receptor affinity, lipophilicity, and mu-opioid–receptor intrinsic efficacy (the “ALE value”) of the prior opioid.

The Social Context of Unhealthy Alcohol Use Among Emergency Department Patients: A Cross Sectional Study
Housing status and additional social determinants of health are important data for clinicians and policy makers to design and implement effective interventions for emergency department (ED) patients with unhealthy alcohol use (UAU).

Implementation of Oral and Extended-Release Naltrexone for the Treatment of Emergency Department Patients With Moderate to Severe Alcohol Use Disorder: Feasibility and Initial Outcomes
We implemented a clinical protocol for ED patients with moderate to severe alcohol use disorder using oral naltrexone and extended-release intramuscular naltrexone together with substance use navigation. Identification of alcohol use disorder, a brief intervention, and initiation of naltrexone resulted in a 15% follow-up rate in formal addiction treatment.

Rapid Adoption of Low-Threshold Buprenorphine Treatment at California Emergency Departments Participating in the CA Bridge Program
Low-threshold ED buprenorphine treatment implemented with a harm reduction approach and active navigation to outpatient addiction treatment was successful in achieving buprenorphine treatment for opioid use disorder in diverse California communities.

High-Dose Buprenorphine Induction in the Emergency Department for Treatment of Opioid Use Disorder
In this case series of 579 cases, 54 clinicians followed a high-dose buprenorphine (monoproduct) protocol. There were no documented episodes of respiratory depression or excessive sedation, and precipitated withdrawal was rare (0.8% of cases) and was not associated with dosing.

Voting with their feet: Social factors linked with treatment for opioid use disorder using same-day buprenorphine delivered in California hospitals
Our study found that a regionally diverse coalition of hospitals implemented a trauma-informed, low-threshold buprenorphine treatment program for patients with Medicaid, unstable housing, and co-methamphetamine use.

Sharp decline in hospital and emergency department initiated buprenorphine for opioid use disorder during COVID-19 state of emergency in California
The COVID-19 California statewide shutdown was associated with an abrupt and large decrease in the progress toward expanded access to OUD treatment.
