Impact of Federal and State Medications for Opioid Use Disorder (MOUD) Policy Changes During the Pandemic

"Gold-standard" medications for opioid use disorder (MOUD) treatment combines FDA-approved medications, primarily methadone and buprenorphine, with behavioral therapies to provide "whole-patient" treatment. Prior to the pandemic, methadone and buprenorphine were subject to greater federal regulations than medications for other substance use disorders, including medication for alcohol use disorder (MAUD), which created barriers to MOUD initiation and retention. These barriers were exacerbated by physical distancing and diminished clinic capacities during the COVID-19 pandemic. To prevent healthcare disruption and expand access to MOUD treatment during the public health emergency, federal and state authorities implemented several MOUD policy changes during the pandemic to reduce barriers to MOUD initiation and retention, which subsequently became permanent. This study is an evaluation of the impacts of these policies on treatment use, retention, and patient outcomes pre- and post-MOUD policy implementation.

Ketones for Opioid Craving

The goal of this clinical trial is to learn if ketone supplementation (KS) works to reduce craving for opioids for adults with opioid use disorder (OUD) undergoing in-patient acute withdrawal management. The main questions it aims to answer are: * Does KS reduce craving for opioids in patients with opioid use disorder? * Does KS reduce symptoms of opioid withdrawal such as low mood and pain? Researchers will compare KS to a placebo to see if KS works to reduce craving for opioids and reduce withdrawal symptoms in adults entering in-patient acute withdrawal management for opioid use disorder. Participants will: * Be given KS or a placebo three (3) times daily for seven (7) days * Complete mood, pain tolerance, and subjective opioid withdrawal assessments

Using Clinical Decision Support to Provide Social Risk-Informed Care for Opioid Use Disorder in the Emergency Department

The overarching goal of this proposal is to integrate patient social risk information into an existing electronic health record (EHR)-based clinical decision support (CDS) tool (CDSv1) to facilitate emergency department (ED)-initiated, social risk-informed opioid use disorder (OUD) medication treatment and ultimately improve treatment adherence and follow up. The investigators will evaluate the feasibility and acceptability of the social care-enhanced CDS tool, CDSv2, (compared to CDSv1) at a single study site (UCSF) as an intervention to increase medication treatment adherence and follow up for adult ED patients experiencing opioid use disorder using a mixed-methods, before-after approach.

tDCS to Decrease Opioid Relapse (UH3)

Investigators will measure behavioral and brain responses following transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex (DLPFC) (anode on right DLPFC, cathode on the left DLPFC) delivered during cognitive control network (CCN) priming. In Phase I, the EEG provided validation of expected changes in these networks following tDCS stimulation of the DLPFC. In this current phase (II), the investigators will perform a larger randomized clinical trial (RCT) (active vs. sham control) to address long-term neurobehavioral outcomes, including opioid relapse, craving, and sustained EEG changes.

Smartphones for Opiate Addiction Recovery

Treatments for opioid addiction exist, but effectiveness is compromised when subjects use illicit opiates during treatment. Reuse rates during treatment can be high, and reducing illicit opiate use during treatment has thus recently become a major NIDA policy goal. The 5-minute battery indicates the numerical probability that a patient will reuse illicit opiates within the next 7-10 days.

Buprenorphine Implementation at Syringe Service Programs to Reduce Overdoses

This study is testing whether offering buprenorphine treatment directly at syringe service programs (SSPs) helps more people start and stay in treatment for opioid use disorder (OUD) than referring them to community buprenorphine treatment providers. Buprenorphine is a medication that helps reduce opioid cravings and withdrawal symptoms. The study compares two ways of connecting people to treatment: Referral to a community treatment provider (usual care before the new program begins). Onsite, low-threshold buprenorphine treatment at the SSP, which allows participants to start medication quickly and without having to establish care at another provider. Participants will be adults who have opioid use disorder and are SSP clients. Each SSP will begin offering the new onsite buprenorphine program at different times during the study. Researchers will collect information before and after the new program begins to see how it affects treatment engagement and health outcomes. The study will also examine how easy or difficult it is for SSPs to start and run the new program, how acceptable it is to staff and participants, and whether it is cost-effective. The overall goal is to find better ways to expand access to life-saving opioid treatment in community-based settings.

Brief Digitally-Enhanced Intervention for Reducing Alcohol Use During MOUD

The goal of this clinical trial is to reduce heavy drinking and enhance medication for opioid use disorder (MOUD) outcomes in individuals receiving MOUD. The main questions it aims to answer are: * Does the brief, digitally-enhanced, virtual psychotherapeutic intervention, called Managing Physical Reactions to Overwhelming Emotions (IMPROVE), impact daily alcohol use and MOUD adherence? * Does the intervention change self-report and physiological responses to intolerance to uncertainty and anxiety sensitivity? Researchers will compare IMPROVE to a control intervention (health education treatment) to see if IMPROVE impacts daily alcohol use and MOUD adherence. Participants will: * Complete a baseline electroencephalography (EEG) and self-report questionnaires. * Complete three one-hour intervention sessions (IMPROVE or control) each one week a part. * Complete a post-intervention EEG and self-report questionnaires. * Complete five ecological momentary assessment (EMA) surveys a day for 21 days. * Complete self-report questionnaires one-month after their last intervention session.

A Bundled Intervention to End Opioid Overdoses

Opioid overdose deaths have reached historically high records in the United States and are particularly concentrated among patients after emergency department (ED) discharge. Evidence-based treatment modules to reduce repeat opioid overdose and mortality are lacking in this patient population. A bundled intervention is proposed, including telehealth, peer support specialist, buprenorphine, and linkage for definitive care, that is designed to increase treatment uptake in this patient population post-ED discharge, reduce repeat opioid overdoses, and end overdose deaths.

Opioid Use Disorder and Pain

The goal of this observational study is to characterize the brain processes of pain avoidance learning dysfunctions in individuals with opioid use disorder (OUD). The main questions it aims to answer are: Compared with healthy controls, do those with OUD exhibit impaired avoidance learning in response to pain? What are the brain processes that are associated with this avoidance learning dysfunction? Do these brain processes serve to predict future use or relapse? Researchers will compare those with OUD and healthy controls to determine avoidance learning dysfunction and its relationship with opioid use. Participants will be performing a learning task inside an fMRI scanner. Those with OUD will also be followed up for a year to determine future opioid use.

Coordinating Outpatient bupreNorphiNe for Emergency Care and Continuing Treatment

The main purpose of this stepped wedge trial will be to test the impact of a bundle of implementation strategies designed to improve ED-outpatient care coordination on long-term buprenorphine retention among adult patients who start buprenorphine for opioid use disorder in a hospital emergency department (ED) and then are referred for continued outpatient buprenorphine treatment after they leave the ED. Our hypothesis is that adopting the bundle of implementation strategies will be associated with subsequent increases in: A) Cumulative number of days with active buprenorphine prescription at 3, 6, and 12 months after patients' initial ED visit (6 months = primary outcome) B) Proportion of patients with active buprenorphine prescriptions without gaps in buprenorphine coverage of more than 7 days at 3, 6, and 12 months after patients' initial ED visit C) Proportion of patients who fill at least 1 outpatient buprenorphine prescription within 30 days of their ED visit D) Clinician reported quality of ED-outpatient care coordination and care transitions

Adaptive Decision Support for Addiction Treatment Master

This study refines and optimizes the EMBED\* clinical decision support (CDS; see NCT03658642) to increase number of ED physicians following standard of care for the administration of buprenorphine to appropriate patients with opioid use disorder. This study does not have open enrollment. Investigators will use a Multiphase Optimization STrategy (MOST) framework study with preparation, optimization, and confirmatory phases. Optimization Phase: This phase has two stages. In stage 1, investigators will conduct a 2x2x2 factorial trial to expand EMBED is expanded to include sustainable implementation strategies: nurse prompt for withdrawal assessment, and targeted clinician prompts to use the CDS along with individualized patient resources to promote equity and motivate readiness to start treatment. In Stage 2, investigators will improve CDS usability via serial randomized testing to inform iterative refinement of the CDS interface and workflow to minimize user errors, task disruption, and abandonment through identification of specific targets for improvement via application of novel CDS outcome measures in serial randomized tests. Evaluation phase: Investigators will conduct a randomized trial to compare the efficacy effectiveness of the optimized package compared to the original on ED-initiation of buprenorphine rates in patients with OUD. \*EMBED is a user user-centered, clinician clinician-facing clinical decision support system integrated into the electronic health record workflow to facilitate initiating buprenorphine in the emergency department by: diagnosing opioid use disorder with a checklist based on the diagnostic criteria of the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, fifth edition), assessing the severity of withdrawal with the Clinical Opioid Withdrawal Scale (COWS), motivating patients to accept treatment with a scripted brief negotiation interview, and automating the electronic health record workflow, including clinical and after visit documentation, order entry, prescribing, and referral for ongoing treatment in the community
