Patient and navigator experiences with the opioid use disorder treatment system in Philadelphia, PA.

BACKGROUND: In 2022, 1413 people in Philadelphia died of an unintentional drug overdose. Addressing the complex challenges within the opioid use disorder (OUD) treatment system requires a comprehensive grasp of multiple system-level siloes from the perspective of patients who are accessing services and certified recovery specialists. Identifying facilitators and barriers to treatment entry and retention are critical. METHODS: We conducted 13 focus groups with 70 people with a history of opioid use in Philadelphia, Pennsylvania. The study recruited participants from non-profit organizations, OUD treatment programs, and street intercept. Certified Recovery Specialists (CRS), people with experience in residential, outpatient, methadone, and buprenorphine programs in Philadelphia, identity-specific groups with Black women, Black men, and Latino men, pregnant and parenting people, and people accessing harm reduction services participated in focus groups. Focus group guides varied by group, but the overarching focus remained on understanding participants' experiences in navigating the OUD treatment system. The research team summarized and edited CRS focus groups and coded all other focus groups for thematic analysis. RESULTS: Most focus group participants (mean age = 45.1 years; 52.9 % men, 40 % Black) had a history with multiple treatment types and reported experiences with different modalities. Salient themes that emerged from analysis included frustrations with the assessment process; reflections on facilitators and barriers by treatment type (residential, methadone, and buprenorphine); and recommendations across treatment modalities. Assessment centers, rather than being easy points of treatment entry, were identified as a major barrier to OUD treatment initiation; issues discussed included length of assessment, limited operating hours, and inadequate withdrawal management. DISCUSSION: The data from the present study were used to develop recommendations for policymakers and other stakeholders of OUD treatment programs to improve care across the spectrum of services. Expansion of residential programs that can support patients with complex comorbid conditions and wounds is needed to prevent delays for patients deemed ineligible for lower levels of care. Housing and income were identified as significant deterrents to initiating drug treatment and greater resources are needed. Greater investment in the OUD workforce is needed, especially expanding staff with lived experience. Findings can enhance OUD treatment programs elsewhere.

Engaging healthcare teams to increase access to medications for opioid use disorder.

OBJECTIVE: To assess the effectiveness of evidence-based quality improvement (EBQI) as an implementation strategy to expand the use of medications for opioid use disorder (MOUD) within nonspecialty settings. DATA SOURCES AND STUDY SETTING: We studied eight facilities in one Veteran Health Administration (VHA) region from October 2015 to September 2022 using administrative data. STUDY DESIGN: Initially a pilot, we sequentially engaged seven of eight facilities from April 2018 to September 2022 using EBQI, consisting of multilevel stakeholder engagement, technical support, practice facilitation, and data feedback. We established facility-level interdisciplinary quality improvement (QI) teams and a regional-level cross-facility collaborative. We used a nonrandomized stepped wedge design with repeated cross sections to accommodate the phased implementation. Using aggregate facility-level data from October 2015 to September 2022, we analyzed changes in patients receiving MOUD using hierarchical multiple logistic regression. DATA COLLECTION/EXTRACTION METHODS: Eligible patients had an opioid use disorder (OUD) diagnosis from an outpatient or inpatient visit in the previous year. Receiving MOUD was defined as having been prescribed an opioid agonist or antagonist treatment or a visit to an opioid substitution clinic. PRINCIPAL FINDINGS: The probability of patients with OUD receiving MOUD improved significantly over time for all eight facilities (average marginal effect [AME]: 0.0057, 95% CI: 0.0044, 0.0070) due to ongoing VHA initiatives, with the probability of receiving MOUD increasing by 0.577 percentage points, on average, each quarter, totaling 16 percentage points during the evaluation period. The seven facilities engaging in EBQI experienced, on average, an additional 5.25 percentage point increase in the probability of receiving MOUD (AME: 0.0525, 95%CI: 0.0280, 0.0769). EBQI duration was not associated with changes. CONCLUSIONS: EBQI was effective for expanding access to MOUD in nonspecialty settings, resulting in increases in patients receiving MOUD exceeding those associated with temporal trends. Additional research is needed due to recent MOUD expansion legislation.

Knowledge of medications for opioid use disorder and associated stigma among primary care professionals.

BACKGROUND: Medications for opioid use disorder (MOUD) are the gold standard. However, significant barriers limit their use in the primary care setting, including limited knowledge of the medications and stigmatizing attitudes. In this study, we assess knowledge levels among primary care-aligned professionals (PCPs) currently in practice, and whether knowledge of MOUD is associated with stigma and treatment attitudes. PARTICIPANTS AND METHODS: Using rosters from the state of Ohio licensing boards, we surveyed 403 physicians, nurse practitioners, and physician associates in 2022, on the mechanism of different MOUD, as well as stigma and treatment attitudes. To assess MOUD knowledge, we employed descriptive and bivariate statistics. We fit four linear regression models, which controlled for empathy towards patients with OUD and provider demographics to assess the relationship between MOUD knowledge and four endpoints: stigma, perceived controllability of opioid use, perceived vulnerability to opioid use disorder, and support for abstinence-only treatment. RESULTS: 43% of participants correctly identified the mechanism of all 3 medications whereas 13% of participants did not identify the mechanism of any MOUD correctly. MOUD knowledge was higher among physicians as compared to nurse practitioners and physician associates. Lower MOUD knowledge was associated with more negative attitudes towards patients with OUD and MOUD treatment. CONCLUSION: Expanding access to MOUD treatment requires a trained and willing health-care professional (HCP) workforce. Our findings highlight considerable variation in clinician knowledge of MOUD and suggest that knowledge levels are also related to negative attitudes towards patients with OUD and MOUD. Training interventions that increase knowledge, as well as focus on stigma reduction, are critical for reducing the longstanding treatment gap for opioid use disorder.

Inpatient initiation of long-acting injectable buprenorphine at a community hospital: A retrospective case series.

OBJECTIVES: Determine if long-acting injectable buprenorphine (LAIB) can be successfully and safely administered in the hospital with minimal sublingual buprenorphine lead-in and potentially improve follow-up engagement in care. METHODS: We performed a retrospective case series of 46 patients who received LAIB while hospitalized at a safety-net community hospital. We abstracted demographic information, details about substance use disorder treatment history, in-hospital buprenorphine initiation methods and follow-up data from inpatient and outpatient electronic medical records. RESULTS: In total, 46 hospitalized patients received LAIB during the study period. The majority of our patients were older Black adults with Medicaid who self-reported intranasal heroin use. A low-dose buprenorphine initiation protocol was used most commonly, either in sublingual or intravenous form, with only two cases of precipitated withdrawal occurring during the buprenorphine initiation process and no cases of precipitated withdrawal after the administration of LAIB. 87% (40) of the patients received LAIB after receiving either sublingual or IV buprenorphine for fewer than the recommended seven days. Of the 46 hospitalized patients who received LAIB, 23 (50%) attended a follow-up addiction medicine appointment within 30 days of discharge. CONCLUSIONS: Hospital administration of LAIB could play an important role in retention in care after hospital discharge.

Racial Differences in Medications for Opioid Use Disorder Initiation in a Carceral Setting.

BACKGROUND: The opioid overdose crisis significantly affects marginalized communities, with people of color experiencing higher rates of overdose and barriers to treatment. The syndemic of opioid use disorder and mass incarceration exacerbates racial health disparities. Some carceral facilities offer medication for addiction treatment, though no significant research explores differences in type of treatment uptake by race in these settings. This study focuses on the racial differences in medications for opioid use disorder (MOUD) preferences among incarcerated individuals. METHODS: A retrospective cohort study was conducted at the Rhode Island Department of Corrections (RIDOC), examining MOUD-type preferences (buprenorphine or methadone) among incarcerated individuals. The study utilized RIDOC electronic medical records from January 1, 2017 to December 31, 2022, involving 3533 unique incarceration events. Participants were categorized by race (White vs non-White) and MOUD status (new initiation vs community continuation), with logistic regression models. RESULTS: The study found no direct racial disparity in preferences for MOUD type. However, an interaction between race and MOUD initiation status significantly influenced MOUD-type preference. Among those initiating MOUD during incarceration, non-White individuals were more likely to choose buprenorphine compared to their White counterparts. CONCLUSIONS: This research provides new insights into the intersection of race, incarceration, and MOUD preferences. While direct racial disparities in MOUD type were not observed, the analysis uncovered a notable interaction effect: race influences the relationship between MOUD initiation status and the selected MOUD treatment during incarceration. Specifically, data demonstrate that the likelihood of choosing buprenorphine varies significantly based on both racial background and whether the treatment was initiated during incarceration or in the community. Further research is needed in different geographic settings to understand the broader implications to help guide equitable healthcare delivery in jails and prisons.

Exploring the Lived Experiences of Medication for Opioid use Disorder Treatment: A Qualitative Study among a Crowdsourced Convenience Sample.

Given the effectiveness of medication for opioid use disorder (MOUD) and low engagement of treatment among people who use drugs (PWUD), it is important to better understand how to engage treatment clients with MOUD care. The current study aimed to achieve this goal by using qualitative methodology to characterize the MOUD treatment experiences. Participants (N = 52) were recruited for an online semi-structured interview. Qualitative analysis revealed varied treatment experiences, with the majority expressing irregular and intermittent MOUD treatment engagement. The therapeutic effects of MOUD in curbing withdrawal symptoms in conjunction with counseling services was frequently mentioned, as well as a preference for methadone maintenance treatment (MMT) to buprenorphine or naltrexone. Many participants described barriers to treatment and continuation of care, including failed drug screens for non-opioid drugs, perceived stigma, and physician-initiated discontinuation of treatment. The current study revealed that patients had favorable experiences with MOUD treatment, particularly when supplemented with counseling services.

Barriers and facilitators to implementing CareConnect: A telehealth, low-barrier buprenorphine bridge clinic in Philadelphia.

INTRODUCTION: Rates of fatal overdose continue to rise in the United States, and most people with opioid use disorder (OUD) are not engaged in evidence-based treatment with medications. In Philadelphia, a city with one of the highest fatal overdose rates in the country, many residents face significant care access barriers. The COVID-19 pandemic - which destabilized the street drug supply and forced many clinics to limit services - worsened this crisis, but also led to regulatory changes that allowed for buprenorphine induction and maintenance visits via telehealth in the U.S. To increase access to buprenorphine across the Philadelphia area and reach individuals who struggle to access care, Penn Medicine developed the CareConnect Warmline in October 2021. CareConnect is embedded in an existing virtual urgent care practice. Staffed by advanced practice providers and substance use navigators (SUNs), CareConnect provides same-day buprenorphine bridge (i.e., short-term) prescriptions and linkage to longitudinal OUD care. OBJECTIVE: To examine barriers and facilitators to implementing CareConnect from the perspective of key stakeholders, including CareConnect leadership, clinicians, and staff, and attitudes and beliefs about providing care for patients with OUD via this model. METHODS: In this qualitative descriptive study, we interviewed 14 participants and used thematic analysis to analyze the data. The sample included CareConnect prescribing clinicians, SUNs, and administrative staff. RESULTS: Our analysis yielded four themes: 1/ CareConnect is a unique program that fills an important care gap; 2/ Benefits of leveraging existing infrastructure; 3/ Importance of an interdisciplinary team; and 4/ Necessity of relationships with outside stakeholders. Prescribing clinicians and administrative staff - most of whom had little experience with OUD care before CareConnect - stressed how embedding the model within an existing virtual clinic and involving experienced SUNs increased their comfort prescribing buprenorphine. However, all participants highlighted how the program's effectiveness is contingent upon buy-in from outside stakeholders, including pharmacists who fill the prescriptions and longitudinal care providers in the community. CONCLUSIONS: Innovative delivery models can help expand OUD care access to individuals who are poorly served by traditional treatment infrastructure. Our findings provide valuable insight to improve and sustain CareConnect and can guide the development and implementation of future programs nationally.

Age and racial and ethnic disparities in filled buprenorphine prescriptions post-emergency department visit in Nevada.

Objectives: We described age, gender, race, and ethnicity associations with filling buprenorphine prescriptions post-emergency department (post-ED) visits. Methods: We analyzed 1.5 years (July 1, 2020-December 31, 2021) of encounter-level Medicaid ED and retail pharmacy claims data obtained from the Nevada Department of Health and Human Services. We studied ED patients with an opioid use disorder (OUD) diagnosis who did not fill a prescription for OUD medications within 6 months before the ED encounter. Using logistic regression, we modeled the associations between the patient's demographic characteristics and the outcome, filling a buprenorphine prescription at a community pharmacy within 14 or 30 days of the ED encounter. Results: Among 2781 ED visits, representing 2094 patients, the median age was 39 years, 54% were male, 18.5% were Black, 11.7% were Hispanic, and 62.3% were White. Only 4% of the ED visits were followed by a filled buprenorphine prescription. Increasing age (14-day window: adjusted odds ratio (aOR) = 0.965, 95% confidence interval [CI]: 0.948-0.983) and being a Black patient (14-day window: aOR: 0.114, 95% CI 0.036-0.361) were both associated with lower odds of filled buprenorphine prescriptions. These results were similar within 30 days of an ED visit. Conclusions: Initiation of buprenorphine following an ED visit remains low among Nevadan Medicaid patients and is less likely with increasing age and among Black patients, despite strong evidence supporting its use. Overburdened EDs, lack of attention from managers, and substance use stigma are among possible explanations. When ED clinicians do write buprenorphine prescriptions, peer recovery support could increase the fill rates.

Implementation of a rural emergency department-initiated buprenorphine program in the mountain west: a study protocol.

BACKGROUND: Opioid related overdose morbidity and mortality continue to significantly impact rural communities. Nationwide, emergency departments (EDs) have seen an increase in opioid use disorder (OUD)-related visits compared to other substance use disorders (SUD). ED-initiated buprenorphine is associated with increased treatment engagement at 30 days. However, few studies assess rural ED-initiated buprenorphine implementation, which has unique implementation barriers. This protocol outlines the rationale and methods of a rural ED-initiated buprenorphine program implementation study. METHODS: This is a two-year longitudinal implementation design with repeated qualitative and quantitative measures of an ED-initiated buprenorphine program in the rural Mountain West. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework outlines intervention assessments. The primary outcome is implementation measured by ED-initiated buprenorphine protocol core components. Reach, adoption, and maintenance are secondary outcomes. External facilitators from an academic institution with addiction medicine and prior program implementation expertise partnered with community hospital internal facilitators to form an implementation team. External facilitators provide ongoing support, recommendations, education, and academic detailing. The implementation team designed and implemented the rural ED-initiated buprenorphine program. The program includes OUD screening, low-threshold buprenorphine initiation, naloxone distribution and administration training, and patient navigator incorporation to provide warm hand off referrals for outpatient OUD management. To address rural based implementation barriers, we organized implementation strategies based on Expert Recommendations for Implementing Change (ERIC). Implementation strategies include ED workflow redesign, local needs assessments, ED staff education, hospital leadership and clinical champion involvement, as well as patient and community resources engagement. DISCUSSION: Most ED-initiated buprenorphine implementation studies have been conducted in urban settings, with few involving rural areas and none have been done in the rural Mountain West. Rural EDs face unique barriers, but tailored implementation strategies with external facilitation support may help address these. This protocol could help identify effective rural ED-initiated buprenorphine implementation strategies to integrate more accessible OUD treatment within rural communities to prevent further morbidity and mortality.

Association Between Length of Buprenorphine or Methadone Use and Nonprescribed Opioid Use Among Individuals with Opioid Use Disorder: A Cohort Study.

BACKGROUND: Opioid use disorder (OUD) affects millions of individuals each year in the United States. Patient retention in medications for opioid use disorder (MOUD) treatment is suboptimal. This study examines and quantifies the associations between each additional month of buprenorphine or methadone use and nonprescribed opioid use. METHODS: Data were obtained from an 18-month longitudinal, observational cohort study of patients (age ≥ 18 years) treated for OUD. Patients completed a baseline self-reported questionnaire between March 2018 and December 2019 and were asked to complete follow-up questionnaires at approximately 3-, 6-, 12-, and 18-months post-baseline until May 2021. Patients treated with buprenorphine or methadone, without taking other MOUD at least 12 months prior to baseline, were included. Outcomes included past 30-day use of prescription opioids nonmedically, heroin, or illegally made fentanyl. A multivariable, multilevel regression model with a binomial distribution and a logit link was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: This study included 353 patients taking buprenorphine (mean [standard deviation, SD] age 39 [11] years; 226 [64%] female), and 785 patients taking methadone (mean [SD] age 42 [12] years; 392 [50%] female). Each additional month of MOUD treatment was associated with a 25% decrease in the odds of past 30-day nonprescribed opioid use for patients taking buprenorphine (aOR [95% CI] = 0.75 [0.68-0.83]), and a 17% decrease for patients taking methadone (aOR = 0.83 [0.79-0.87]). The COVID-19 pandemic (aOR = 9.29 [2.96-29.17]; aOR = 3.19 [1.74-5.86]) and MOUD adverse reaction experiences (aOR = 3.07 [1.11-8.48]; aOR = 2.51 [1.01-6.22]) were significantly associated with higher odds of nonprescribed opioid use among buprenorphine and methadone groups. CONCLUSION: Among patients treated with buprenorphine or methadone, with each additional treatment month since baseline, those who continued with treatment appeared to be more likely to report 17% to 25% decreased odds of past 30-day nonprescribed opioid use. Our findings can be used by clinicians in the shared decision-making process with patients, emphasizing the value of sustained retention in MOUD.

Comparative effectiveness of extended-release naltrexone and sublingual buprenorphine for treatment of opioid use disorder among Medicaid patients.

BACKGROUND AND AIMS: Extended-release naltrexone (XR-NTX) and sublingual buprenorphine (SL-BUP) are both approved for opioid use disorder (OUD) treatment in any medical setting. We aimed to compare the real-world effectiveness of XR-NTX and SL-BUP. DESIGN AND SETTING: This was an observational active comparator, new user cohort study of Medicaid claims records for patients in New Jersey and California, USA, 2016-19. PARTICIPANTS/CASES: The participants were adult Medicaid patients aged 18-64 years who initiated XR-NTX or SL-BUP for maintenance treatment of OUD and did not use medications for OUD in the 90 days before initiation. Our cohort included 1755 XR-NTX and 9886 SL-BUP patients. MEASUREMENTS: We examined two outcomes up to 180 days after medication initiation: (1) composite of medication discontinuation and death and (2) composite of overdose and death. FINDINGS: In adjusted analyses, treatment with XR-NTX was more likely to result in discontinuation or death by the end of follow-up than treatment with SL-BUP: cumulative risk 75.9% [95% confidence interval (CI) = 73.9%, 77.9%] versus 62.2% (95% CI = 61.2%, 63.2%), respectively (risk difference = 13.7 percentage points, 95% CI = 11.4, 16.0). There was minimal difference in the cumulative risk of overdose or death by the end of follow-up: XR-NTX 3.9% (95% CI = 3.0%, 4.8%) versus SL-BUP 3.3% (95% CI = 2.9%, 3.7%); risk difference = 0.5 percentage points, 95% CI = -0.4, 1.5. Results were consistent across sensitivity analyses. CONCLUSIONS: Medicaid patients in California and New Jersey, USA, receiving treatment for opioid use disorder stayed in treatment longer on sublingual buprenorphine than on extended-release naltrexone, but the risk of overdose was similar. Most patients in this study discontinued medication within 6 months, regardless of which medication was initiated.

Healthcare utilisation and associated costs for methadone versus buprenorphine recipients: Examination of interlinked primary and secondary care electronic health records in England.

INTRODUCTION: More evidence for patterns of healthcare utilisation and associated costs among people receiving opioid agonist therapy (OAT) is needed. We investigated primary and secondary healthcare usage and costs among methadone and buprenorphine recipients in England. METHODS: We conducted a cohort study using the Clinical Practice Research Datalink GOLD and Aurum databases of patients who were prescribed OAT between 1 January 2007 and 31 July 2019. The cohort was linked to Hospital Episode Statistics admitted patient care, outpatient and emergency department data, neighbourhood- and practice-level Index of Multiple Deprivation quintiles and mortality records. Negative binomial regression models were applied to estimate weighted rate ratios (wRR) of healthcare utilisation. Total and mean costs were calculated using Unit Costs of Health and Social Care and the National Healthcare Service Payment by Results National Tariffs. RESULTS: Among 12,639 patients observed over 39,016 person-years, we found higher rate of hospital admissions (wRR 1.18; 1.08-1.28) among methadone compared with buprenorphine recipients. The commonest hospital discharge diagnoses among methadone patients were infectious diseases (19.2%), mental and behavioural disorders (17.0%) and drug-related poisoning (16.5%); the three commonest among buprenorphine patients were mental and behavioural diseases (21.5%), endocrine (13.8%) and genitourinary system diseases (13.1%). Methadone patients had similar mean costs compared with buprenorphine patients (cost difference: £539.01; 432.11-1006.69). DISCUSSION AND CONCLUSIONS: Differences in healthcare utilisation frequency for methadone versus buprenorphine recipients were observed. The differences in associated costs were mainly driven by hospital admissions. These findings offer valuable insights for optimising care strategies and resource allocation for OAT recipients.

Successful administration of extended-release buprenorphine in the emergency department.

INTRODUCTION: The ongoing opioid epidemic in the United States has resulted in a substantial increase in overdose deaths and related morbidity and mortality. Given that emergency departments (ED) frequently serve as the initial point of contact for individuals experiencing opioid overdose or seeking treatment for opioid use disorder (OUD), ED clinicians have a pivotal role to play in providing prompt and effective treatment for OUD. While ED clinicians routinely administer sublingual and other transmucosal formulations of buprenorphine, extended-release buprenorphine (BUP-XR) remains underutilized in the ED. CASE REPORT: We present a case involving the successful administration of BUP-XR in the ED to a patient experiencing spontaneous opioid withdrawal. The patient tolerated test dosing of sublingual buprenorphine (BUP-SL) and subsequently received BUP-XR in the ED. Following this intervention, the patient was referred to the hospital-affiliated substance use disorder outpatient clinic, where he has since demonstrated successful follow-up and retention in treatment. CONCLUSION: Our report adds to the existing limited literature on the administration of BUP-XR in the ED and highlights the need for more comprehensive clinician teaching and guidance, as well as the establishment of in-hospital protocols for BUP-XR. Despite these challenges, our case indicates that initiating BUP-XR could be a viable and effective option for ED patients with OUD.

Physician's Attitudes Toward Patients With Opioid Use Disorder and Use of Medications for Opioid Use Disorder Vary by Training.

OBJECTIVES: This study compared whether different addiction treatment educational experiences were associated with physicians' attitudes toward patients with opioid use disorder (OUD) and perceived efficacy of medications for opioid use disorder (MOUD). METHODS: Ohio physicians (n = 2757) with and without a waiver to prescribe buprenorphine (Drug Addiction Treatment Act 2000 [DATA 2000] waiver) were surveyed regarding their attitudes toward treating patients with OUD and on the effectiveness of MOUD. We divided physicians into 3 groups: physicians with DATA 2000 waivers, non-waivered physicians with experiential training, and non-waivered physicians without experiential training. We defined experiential training as educational experience directly working with individuals with OUD including those in recovery. Analysis of variance was used to detect statistically significant group differences. RESULTS: We found significant main effect differences in attitudes toward patients with OUD and perceived efficacy of MOUD between groups (P ≤ .01) for all but one attitude. Post hoc comparisons revealed waivered physicians had the most favorable attitudes. Among physicians without a waiver, those with experiential training had significantly more favorable attitudes toward treating OUD and perceived MOUD to be more effective, including items such as "OUD are treatable illnesses" and "medication assisted treatment is a crucial part of treatment for OUD." CONCLUSION: The results suggest that physicians with DATA 2000 waiver and experiential training, as compared to physicians without either a waiver or experiential training in OUD, are associated with less stigmatizing views of treating patients with OUD and prescribing MOUD. While legislation in December 2022 eliminated DATA 2000 waiver training requirement, these findings suggest an ongoing need for training opportunities.

Qualitative Assessment of Barriers to Buprenorphine Access: The Role of Pharmacies.

BACKGROUND: Patients continue to face challenges accessing medication for opioid use disorder (MOUD) despite attempts to loosen prescribing restrictions and streamline service provision. Past research has mainly focused on potential barriers surrounding prescribing practices for buprenorphine, but has had limited investigation into the role of pharmacies. OBJECTIVE: This study investigates the role of both pharmacists and pharmacies in creating or circumventing barriers to accessing buprenorphine for individuals in Georgia seeking medication for opioid use disorder (MOUD). METHODS: Semi-structured interviews of pharmacists across 12 access and no access pharmacies were used to create a codebook of 179 discreet statements. The (N = 12) 20-35-minute phone interviews included questions addressing substance use, pharmacy practices, treatment, harm reduction, and psychoeducation. RESULTS: Pharmacists widely agreed that opioid use has caused negative effects on community members (N = 11), that buprenorphine formulation stocking decisions are made based on patient needs (N = 11), and that buprenorphine is relatively easy to stock (N = 10). Additionally, respondents generally stated that buprenorphine is a helpful tool for treating opioid use disorder (OUD) (N = 12) but some reported positive experiences while others reported challenging or negative experiences with patients receiving buprenorphine (N = 7). Finally, few (N = 4) pharmacists agreed that they could benefit from extra training despite many asserting that training is important to inform their own practice (N = 8). CONCLUSION: Results from respondents generally show that training may be beneficial for pharmacists to develop an enhanced understanding of addiction and treatment. Enhanced effort to stock different formulations or dosages of buprenorphine and develop relationships with prescribers may increase community access.

Reconsidering the usefulness of long-term high-dose buprenorphine.

Buprenorphine has been successfully used for decades in the treatment of opioid use disorder, yet there are complexities to its use that warrant attention to maximize its utility. While the package insert of the combination product buprenorphine\naloxone continues to recommend a maximum dose of 16 mg daily for maintenance, the emergence of fentanyl and synthetic analogs in the current drug supply may be limiting the effectiveness of this standard dose. Many practitioners have embraced and appropriately implemented novel practices to mitigate the sequelae of our current crisis. It has become common clinical practice to stabilize patients with 24 - 32 mg of buprenorphine daily at treatment initiation. Many of these patients, however, are maintained on these high doses (>16 mg/d) indefinitely, even after prolonged stability. Although this may be a necessary strategy in the short term, there is little evidence to support its safety and efficacy, and these high doses may be exposing patients to more complications and side effects than standard doses. Commonly known side effects of buprenorphine that are likely dose-related include hyperhidrosis, sedation, decreased libido, constipation, and hypogonadism. There are also complications related to the active metabolite of buprenorphine (norbuprenorphine) which is a full agonist at the mu opioid receptor and does not have a ceiling on respiratory suppression. Such side effects can lead to medical morbidity as well as decreased medication adherence, and we, therefore, recommend that after a period of stabilization, practitioners consider a trial of decreasing the dose of buprenorphine toward standard dose recommendations. Some patients' path of recovery may never reach this stabilization phase (i.e., several months of adherence to medications, opioid abstinence, and other clinical indicators of stability). Side effects of buprenorphine may not have much salience when patients are struggling for survival and safety, but for those who are fortunate enough to advance in their recovery, the side effects become more problematic and can limit quality of life and adherence.

Impact of childhood adversity on acute subjective effects of stimulant and opioid drugs: Evidence from placebo-controlled studies in healthy volunteers.

BACKGROUND AND AIMS: Early-life adversities are known to alter drug reward processing in rodents. Despite the well-known link between early adversity and the risk of substance use disorder, few studies have measured how childhood adversity affects human drug reward. Here, we assessed the relationship between historical childhood adversities and responses to single doses of methamphetamine, d-amphetamine or buprenorphine in healthy participants. METHODS: Using a secondary analysis approach, we assessed the impact of childhood adversity on drug effects from three randomised, placebo-controlled studies in which healthy volunteers received methamphetamine (20 mg oral; n = 35), d-amphetamine (20 mg oral; n = 54) or buprenorphine (0.2 mg sublingual; n = 35). Ratings of feeling effect, liking, disliking, feeling high and wanting more of the drug were collected 15-210 min post-administration, and heart rate changes were analysed using random-intercept mixed-effect models. The area under the curve from these and previous studies was calculated to visualise the relationship between childhood adversity severity and drug effects. RESULTS: Greater childhood adversity was associated with reduced feel effects (significant three-way interactions b = -0.07, 95% CI [-0.12, -0.02], p = 0.009), like effects (b = -0.07, 95% CI [-0.13, -0.00], p = 0.038) and feel high (b = -0.06, 95% CI [-0.10, -0.01], p = 0.020) towards the stimulant drugs 90-180 min post-administration. CONCLUSIONS: Childhood adversity was not significantly associated with other subjective or heart rate responses to the drugs. Overall, participants with more childhood adversities reported dampened subjective responses to stimulant drugs, but not to buprenorphine. Future studies should examine the generalisability of these relationships, to identify the mechanisms underlying the link between childhood adversity and drug responsiveness.

Perioperative Management of Buprenorphine at an Urban Academic Medical Center.

INTRODUCTION: Buprenorphine is a partial mu opioid receptor agonist with high affinity to its receptor, which raises concerns of blocking or displacing full opioid agonists when used during the perioperative period of surgical patients. However, buprenorphine itself has high analgesic potency and discontinuing buprenorphine may lead to suboptimal pain control and risk for opioid use disorder relapse. There is limited data for the continuation of buprenorphine perioperatively. METHODS: This study is a retrospective cohort study of adult surgical patients taking buprenorphine for opioid use disorder at an urban, teaching, level 1 trauma center. Patients were split into two groups based on whether buprenorphine was continued (n = 46) or held (n = 28) within the first 48 h after surgery. RESULTS: Those who had buprenorphine continued in the first 48 h postoperatively required half the dose of nonbuprenorphine opioids compared to those who had buprenorphine held (113.25 versus 255.75 oral morphine equivalents, P = 0.0040). Both groups had a similar level of analgesia and incidence of adverse events. Nearly all patients who continued buprenorphine in the first 48 h postoperatively were discharged on this agent, while only half of patients who had buprenorphine held were restarted on it at discharge (92.68% versus 56.52%, P = 0.0013). CONCLUSIONS: This present study found lower nonbuprenorphine opioid requirements in patients with continued versus held perioperative buprenorphine use with no difference in degree of analgesia.
