Provider Perceptions toward Extended-Release Buprenorphine for Treatment of Opioid Use Disorder.

OBJECTIVES: The persistence of the opioid crisis and the proliferation of synthetic fentanyl have heightened the demand for the implementation of novel delivery mechanisms of pharmacotherapy for the treatment of opioid use disorder, including injectable extended-release buprenorphine (buprenorphine-ER). The purpose of this study was to understand provider-level barriers to prescribing buprenorphine in order to facilitate targeted strategies to improve implementation for patients who would benefit from this novel formulation. METHODS: Using an interview template adapted from the Consolidated Framework for Implementation Research (CFIR), we conducted structured focus group interviews with 20 providers in an outpatient addiction clinic across 4 sessions to assess providers' perceptions of buprenorphine-ER. Ninety-four unique comments were identified and deductively coded using standardized CFIR constructs. RESULTS: Providers expressed mixed receptivity and confidence in using buprenorphine-ER. Although providers could identify a number of theoretical advantages to the injectable formulation over sublingual buprenorphine, many expressed reservations about using it due to inexperience, negative patient experiences, uncertainties about patient candidacy, cost, and logistical constraints. CONCLUSIONS: Provider concerns about buprenorphine-ER may limit utilization. Some concerns may be mitigated through improved education, research, and logistical support. Given the putative benefits of buprenorphine-ER, future research should target barriers to implementation, in part based on hypotheses generated by these findings.

Hepatitis C Cascade of Care in a Multidisciplinary Substance Use Bridge Clinic Model in Tennessee.

Many barriers prevent individuals with substance use disorders from receiving hepatitis C virus (HCV) treatment. This study describes 96 patients with active HCV treated in an opioid use disorder bridge clinic model. Of 33 patients who initiated treatment, 25 patients completed treatment, and 13 patients achieved sustained virologic response.

Impact of inpatient addiction psychiatry consultation on opioid use disorder outcomes.

BACKGROUND AND OBJECTIVES: Addiction consultation services provide access to specialty addiction care during general hospital admission. This study assessed opioid use disorder (OUD) outcomes associated with addiction consultation. METHODS: Retrospective cohort study of individuals with OUD admitted to an academic medical center between 2018 and 2023. The exposure was addiction consultation. Outcomes included initiating medication for OUD (MOUD), hospital length of stay, before-medically-advised (BMA) discharge, and 30- and 90-day postdischarge acute care utilization. RESULTS: Of 26,766 admissions (10,501 patients) with OUD, 2826 addiction consultations were completed. Consultation cohort was more likely to be young, male, and White than controls. Consultation was associated with greater MOUD initiation (adjusted odds ratio [aOR], 5.07; 95% confidence interval [CI], 4.41-5.82), fewer emergency department visits at 30 (aOR, 0.78; 95% CI, 0.67-0.92) and 90 (aOR, 0.79; 95% CI, 0.69-0.89) days, and fewer hospitalizations at 30 (aOR, 0.65; 95% CI, 0.56 to 0.76) and 90 (aOR, 0.67; 95% CI, 0.59-0.76) days. Additionally, consultation patients were more likely to have a longer hospital stay and leave BMA. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Addiction consultation was associated with increased MOUD initiation and reduced postdischarge acute care utilization. This is the largest study to date showing a significant association between addiction psychiatry consultation and improved OUD outcomes when compared to controls. The observed reduction in postdischarge acute care utilization remains even after adjusting for MOUD initiation. Disparities in access to addiction consultation warrant further study.

Effect of a Co-Located Bridging Recovery Initiative on Hospital Length of Stay Among Patients With Opioid Use Disorder: The BRIDGE Randomized Clinical Trial.

Importance: Co-located bridge clinics aim to facilitate a timely transition to outpatient care for inpatients with opioid use disorder (OUD); however, their effect on hospital length of stay (LOS) and postdischarge outcomes remains unclear. Objective: To evaluate the effect of a co-located bridge clinic on hospital LOS among inpatients with OUD. Design, Setting, and Participants: This parallel-group randomized clinical trial recruited 335 adult inpatients with OUD seen by an addiction consultation service and without an existing outpatient clinician to provide medication for OUD (MOUD) between November 25, 2019, and September 28, 2021, at a tertiary care hospital affiliated with a large academic medical center and its bridge clinic. Intervention: The bridge clinic included enhanced case management before and after hospital discharge, MOUD prescription, and referral to a co-located bridge clinic. Usual care included MOUD prescription and referrals to community health care professionals who provided MOUD. Main Outcomes and Measures: The primary outcome was the index admission LOS. Secondary outcomes, assessed at 16 weeks, were linkage to health care professionals who provided MOUD, MOUD refills, same-center emergency department (ED) and hospital use, recurrent opioid use, quality of life (measured by the Schwartz Outcome Scale-10), overdose, mortality, and cost. Analysis was performed on an intent-to-treat basis. Results: Of 335 participants recruited (167 randomized to the bridge clinic and 168 to usual care), the median age was 38.0 years (IQR, 31.9-45.7 years), and 194 (57.9%) were male. The median LOS did not differ between arms (adjusted odds ratio [AOR], 0.94 [95% CI, 0.65-1.37]; P = .74). At the 16-week follow-up, participants referred to the bridge clinic had fewer hospital-free days (AOR, 0.54 [95% CI, 0.32-0.92]), more readmissions (AOR, 2.17 [95% CI, 1.25-3.76]), and higher care costs (AOR, 2.25 [95% CI, 1.51-3.35]), with no differences in ED visits (AOR, 1.15 [95% CI, 0.68-1.94]) or deaths (AOR, 0.48 [95% CI, 0.08-2.72]) compared with those receiving usual care. Follow-up calls were completed for 88 participants (26.3%). Participants referred to the bridge clinic were more likely to receive linkage to health care professionals who provided MOUD (AOR, 2.37 [95% CI, 1.32-4.26]) and have more MOUD refills (AOR, 6.17 [95% CI, 3.69-10.30]) and less likely to experience an overdose (AOR, 0.11 [95% CI, 0.03-0.41]). Conclusions and Relevance: This randomized clinical trial found that among inpatients with OUD, bridge clinic referrals did not improve hospital LOS. Referrals may improve outpatient metrics but with higher resource use and expenditure. Bending the cost curve may require broader community and regional partnerships. Trial Registration: ClinicalTrials.gov Identifier: NCT04084392.

Medical and genetic correlates of long-term buprenorphine treatment in the electronic health records.

Despite the benefits associated with longer buprenorphine treatment duration (i.e., >180 days) (BTD) for opioid use disorder (OUD), retention remains poor. Research on the impact of co-occurring psychiatric issues on BTD has yielded mixed results. It is also unknown whether the genetic risk in the form of polygenic scores (PGS) for OUD and other comorbid conditions, including problematic alcohol use (PAU) are associated with BTD. We tested the association between somatic and psychiatric comorbidities and long BTD and determined whether PGS for OUD-related conditions was associated with BTD. The study included 6686 individuals with a buprenorphine prescription that lasted for less than 6 months (short-BTD) and 1282 individuals with a buprenorphine prescription that lasted for at least 6 months (long-BTD). Recorded diagnosis of substance addiction and disorders (Odds Ratio (95% CI) = 22.14 (21.88-22.41), P = 2.8 × 10-116), tobacco use disorder (OR (95% CI) = 23.4 (23.13-23.68), P = 4.5 × 10-111), and bipolar disorder (OR(95% CI) = 9.70 (9.48-9.92), P = 1.3 × 10-91), among others, were associated with longer BTD. The PGS of OUD and several OUD co-morbid conditions were associated with any buprenorphine prescription. A higher PGS for OUD (OR per SD increase in PGS (95%CI) = 1.43(1.16-1.77), P = 0.0009), loneliness (OR(95% CI) = 1.39(1.13-1.72), P = 0.002), problematic alcohol use (OR(95%CI) = 1.47(1.19-1.83), P = 0.0004), and externalizing disorders (OR(95%CI) = 1.52(1.23 to 1.89), P = 0.0001) was significantly associated with long-BTD. Associations between BTD and the PGS of depression, chronic pain, nicotine dependence, cannabis use disorder, and bipolar disorder did not survive correction for multiple testing. Longer BTD is associated with diagnoses of psychiatric and somatic conditions in the EHR, as is the genetic score for OUD, loneliness, problematic alcohol use, and externalizing disorders.

Comparison of phenobarbital monotherapy to a benzodiazepine-based regimen for management of alcohol withdrawal syndrome in trauma patients.

BACKGROUND: Alcohol withdrawal syndrome (AWS) is associated with increased morbidity and mortality in the trauma population. Benzodiazepines (BZDs) are standard of care for AWS; however, given the risk of delirium with BZDs and reports of BZD-refractory withdrawal, phenobarbital (PHB) has emerged as an alternative therapy for AWS. Safety and efficacy studies of PHB for AWS in trauma patients are lacking. Our aim was to compare a BZD versus PHB protocol in the management of AWS in trauma patients. METHODS: We performed a retrospective cohort study at a level 1 trauma center of patients at risk for AWS managed with either a BZD or a low-dose oral PHB regimen. Patients were excluded if they were taking BZDs or barbiturates before admission, received propofol or dexmedetomidine before initiation of the study drug, presented with delirium tremens or seizures, or died or discharged within 24 hours of presentation. The primary outcome was complicated AWS (seizures or alcohol withdrawal delirium/delirium tremens). Secondary outcomes included uncomplicated AWS; therapy escalation; oversedation; delirium-, intensive care unit-, and ventilator-free days; and length of stay. RESULTS: A total of 411 patients were identified; 118 received BZD, and 293 received PHB. The odds of developing complicated AWS with PHB versus BZD-based therapy were not statistically significant (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.21-1.39); however, patients receiving PHB were less likely to develop uncomplicated AWS (OR, 0.08; 95% CI, 0.04-0.14) and less likely to require escalation of therapy (OR, 0.45; 95% CI, 0.24-0.84). The PHB group had a length of stay 3.1 days shorter than the BZD group ( p = 0.002). There was no difference in intensive care unit-, ventilator-, or delirium-free days. CONCLUSION: A PHB-based protocol for the management of AWS is a safe and effective alternative to BZD-based regimens in trauma patients. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

More Effective Communication During Inpatient Addiction Treatment.

In this commentary, the authors argue that historical approaches to inpatient addiction treatment favoring more confrontational, expert-centric, or paternalistic undercurrents continue to permeate the hidden curriculum in medical training. These older approaches unfortunately continue to inform how many trainees learn to approach inpatient addiction treatment. The authors go on to provide several examples of how clinical challenges specific to inpatient addiction treatment can be addressed by employing principles of motivational interviewing, harm reduction, and psychodynamic thought. Key skills are described including accurate reflection, recognition of countertransference, and assisting patients to sit with important dialectics. The authors call for greater training of attending physicians, precepting advanced practice providers, and trainees across these disciplines, as well as further study of whether systematic improvements in such provider communication may alter patient outcomes.

Rewriting the Hidden Curriculum via Addiction Consult Services: Meeting Patients Where They Are At.

Addiction Consult Services (ACS) deliver evidence-based care for patients with substance use disorder (SUD) during the course of general hospital admissions. Stigma toward patients with SUD is a known phenomenon and is part of the "hidden curriculum" that permeates medical training and healthcare settings. ACS have the potential to rewrite the hidden curriculum around SUD and to teach medical students and other trainees how to compassionately care for this patient population. Here, the authors explore the role of stigma within the hidden curriculum of medical training and outline how ACS can successfully contribute to combatting this stigma. The authors highlight two institutions' approaches to educational initiatives that incorporate health professional trainees into ACS. The authors end by providing a vision of how expansion of ACS can promote interdisciplinary learning for healthcare providers amidst the changing landscape of SUD treatment in the USA.

Implementation of a hospital-based intervention for MOUD initiation and referral to a Bridge Clinic for opioid use disorder.

INTRODUCTION: Individuals struggling with opioid use disorder (OUD) utilize the adult emergency department (ED) and psychiatric emergency department at high rates. In 2019, Vanderbilt University Medical Center created a system for individuals identified in the emergency department with OUD to transition care to a Bridge Clinic for up to three months of comprehensive behavioral health treatment, alongside primary care, infectious diseases, and pain management, regardless of their insurance status. METHODS: We conducted 20 interviews with patients enrolled in treatment in our Bridge Clinic and 13 providers in the psychiatric emergency department and emergency department. Our provider interviews focused on understanding experiences identifying people with OUD and referring them to care at the Bridge Clinic. Our patient interviews focused on understanding their experiences of care-seeking, the referral process, and their satisfaction with treatment at the Bridge Clinic. RESULTS: Our analysis generated 3 major themes around patient identification, referral, and quality of care from providers and patients. The study found general agreement between both groups around the high quality of care delivered in the Bridge Clinic compared with OUD treatment at nearby treatment facilities, specifically because it offered a stigma-free environment for the delivery of medication for addiction therapy and psychosocial support. Providers highlighted the lack of a systematic strategy for identifying people with OUD in an ED setting. They also found the referral process cumbersome because it could not be done through EPIC and there were limited patient slots available. In contrast, patients reported a smooth and simple referral from the ED to the Bridge Clinic. CONCLUSIONS: Creating a Bridge Clinic for comprehensive OUD treatment at a large university medical center has been challenging but has resulted in the creation of a comprehensive care system that prioritizes quality care. Funding to increase the number of patient slots available, coupled with an electronic system of patient referral, will increase the reach of the program to some of Nashville's most vulnerable constituents.

Assessment of a Naloxone Coprescribing Alert for Patients at Risk of Opioid Overdose: A Quality Improvement Project.

BACKGROUND: Patients taking high doses of opioids, or taking opioids in combination with other central nervous system depressants, are at increased risk of opioid overdose. Coprescribing the opioid-reversal agent naloxone is an essential safety measure, recommended by the surgeon general, but the rate of naloxone coprescribing is low. Therefore, we set out to determine whether a targeted clinical decision support alert could increase the rate of naloxone coprescribing. METHODS: We conducted a before-after study from January 2019 to April 2021 at a large academic health system in the Southeast. We developed a targeted point of care decision support notification in the electronic health record to suggest ordering naloxone for patients who have a high risk of opioid overdose based on a high morphine equivalent daily dose (MEDD) ≥90 mg, concomitant benzodiazepine prescription, or a history of opioid use disorder or opioid overdose. We measured the rate of outpatient naloxone prescribing as our primary measure. A multivariable logistic regression model with robust variance to adjust for prescriptions within the same prescriber was implemented to estimate the association between alerts and naloxone coprescribing. RESULTS: The baseline naloxone coprescribing rate in 2019 was 0.28 (95% confidence interval [CI], 0.24-0.31) naloxone prescriptions per 100 opioid prescriptions. After alert implementation, the naloxone coprescribing rate increased to 4.51 (95% CI, 4.33-4.68) naloxone prescriptions per 100 opioid prescriptions (P < .001). The adjusted odds of naloxone coprescribing after alert implementation were approximately 28 times those during the baseline period (95% CI, 15-52). CONCLUSIONS: A targeted decision support alert for patients at risk for opioid overdose significantly increased the rate of naloxone coprescribing and was relatively easy to build.

Implementation of a Hub-and-Spoke Partnership for Opioid Use Disorder Treatment in a Medicaid Nonexpansion State.

Hub-and-spoke (H&S) partnerships for managing opioid use disorder vary by U.S. state. This column provides the first description of the development of an H&S partnership in Tennessee, a Medicaid nonexpansion state. Medicaid expansion allows states to fund evidence-based substance use disorder treatment and community-based psychosocial interventions. In an H&S model in a Medicaid nonexpansion context, federal grant support must fund not only treatment itself but also the creation and maintenance of parallel billing and documentation processes for various partners, reducing the funds available for patient care.

Bridging Recovery Initiative Despite Gaps in Entry (BRIDGE): study protocol for a randomized controlled trial of a bridge clinic compared with usual care for patients with opioid use disorder.

BACKGROUND: Patients with substance use disorders are overrepresented among general hospital inpatients, and their admissions are associated with longer lengths of stay and increased readmission rates. Amid the national opioid crisis, increased attention has been given to the integration of addiction with routine medical care in order to better engage such patients and minimize fragmentation of care. General hospital addiction consultation services and transitional, hospital-based "bridge" clinics have emerged as potential solutions. We designed the Bridging Recovery Initiative Despite Gaps in Entry (BRIDGE) trial to determine if these clinics are superior to usual care for these patients. METHODS: This single-center, pragmatic, randomized controlled clinical trial is enrolling hospitalized patients with opioid use disorder (OUD) who are initiating medication for OUD (MOUD) in consultation with the addiction consult service. Patients are randomized for referral to a co-located, transitional, multidisciplinary bridge clinic or to usual care, with the assignment probability being determined by clinic capacity. The primary endpoint is hospital length of stay. Secondary endpoints include quality of life, linkage to care, self-reported buprenorphine or naltrexone fills, rate of known recurrent opioid use, readmission rates, and costs. Implementation endpoints include willingness to be referred to the bridge clinic, attendance rates among those referred, and reasons why patients were not eligible for referral. The main analysis will use an intent-to-treat approach with full covariate adjustment. DISCUSSION: This ongoing pragmatic trial will provide evidence on the effectiveness of proactive linkage to a bridge clinic intervention for hospitalized patients with OUD initiating evidence-based pharmacotherapy in consultation with the addiction consult service. TRIAL REGISTRATION: ClinicalTrials.gov NCT04084392 . Registered on 10 September 2019. The study has been approved by the Vanderbilt Institutional Review Board. The current approved protocol is dated version May 12, 2021.

The Need for Biochemical Testing for Alcohol in Integrated Addiction Treatment Settings During the Opioid Epidemic.

As the opioid crisis drives expansion of integrated opioid use disorder (OUD) treatment programs in generalist settings, these programs will contend with significant rates of co-occurring alcohol use. The authors present a brief literature review and commentary regarding nondisordered and disordered alcohol use in OUD treatment settings and biochemical detection techniques. Biochemical testing for alcohol in integrated OUD treatment settings is both important for detecting alcohol use disorder and feasible. Breathalyzer testing may assist with management of acutely intoxicated patients. Biochemical testing for alcohol is an important part of integrated OUD treatment. More research is needed on the impact of alcohol use on OUD treatment outcomes and the role of breathalyzer testing in management of intoxicated patients in the outpatient setting.

Overlapping Mechanisms of Recovery Between Professional Psychotherapies and Alcoholics Anonymous.

BACKGROUND: Much research over the past 25 years has focused on elucidating the mechanisms by which Alcoholics Anonymous (AA) affects behavioral change in its participants. In addition to research on the spiritual mechanisms for which AA is best known in the popular conception, research on mechanisms of recovery (MOR) has predominantly supported social, cognitive, and affective mechanisms that are also present in many professional psychotherapies. AIM: This paper compares and contrasts the theorized MOR of AA with those found in several common professional psychotherapies to illustrate analogous elements. METHODS: Literature review, summary, and synthesis of studies examining the MOR of both AA and common psychotherapies including analytic/dynamic therapies, cognitive-behavioral therapies, and acceptance and mindfulness-based therapies. RESULTS: There exists a significant overlap in theorized MOR of AA and mainstream, professional psychotherapies. Mechanisms with the greatest overlap include those mobilizing stress and coping theory, behavioral choice theory, and social learning theory, while mechanisms more unique to AA compared to professional psychotherapies mobilize social control theory to a greater degree. CONCLUSIONS: In caring for patients with addiction, practicing clinicians will find it useful to be aware of overlapping analogous elements found in the AA program and professional psychotherapies and how they can complement one another.

Correlates of Opioid Abstinence in a 42-Month Posttreatment Naturalistic Follow-Up Study of Prescription Opioid Dependence.

OBJECTIVE: The natural course of prescription opioid use disorder has not been examined in longitudinal studies. The current study examined correlates of opioid abstinence over time after completion of a treatment trial for prescription opioid dependence. METHODS: The multisite Prescription Opioid Addiction Treatment Study examined different durations of buprenorphine-naloxone treatment and different intensities of counseling to treat prescription opioid dependence, as assessed by DSM-IV; following the clinical trial, a longitudinal study was conducted from March 2009-January 2013. At 18, 30, and 42 months after treatment entry, telephone interviews were conducted (N = 375). In this exploratory, naturalistic study, logistic regression analyses examined the association between treatment modality (including formal treatment and mutual help) and opioid abstinence rates at the follow-up assessments. RESULTS: At the 3 follow-up assessments, approximately half of the participants reported engaging in current substance use disorder treatment (47%-50%). The most common treatments were buprenorphine maintenance (27%-35%) and mutual-help group attendance (27%-30%), followed by outpatient counseling (18%-23%) and methadone maintenance (4%). In adjusted analyses, current opioid agonist treatment showed the strongest association with current opioid abstinence (odds ratios [ORs] = 5.4, 4.6, and 2.8 at the 3 assessments), followed by current mutual-help attendance (ORs = 2.2, 2.7, and 1.9); current outpatient counseling was not significantly associated with abstinence in the adjusted models. CONCLUSIONS: While opioid agonist treatment was most strongly associated with opioid abstinence among patients with prescription opioid dependence over time, mutual-help group attendance was independently associated with opioid abstinence. Clinicians should consider recommending both of these interventions to patients with opioid use disorder. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00316277​.
