The relationship between addiction profile and parental attitudes in patients with opioid use disorder

ABSTRACT Background and objective We aimed to compare the perceived parental attitudes experienced by adults with opioid use disorder (OUD) with a healthy group and to examine its effect on the addiction profile. Methods Our study included 71 male patients diagnosed with OUD based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria and 71 male volunteers. Patients included in the study and healthy control group were subjected to the Sociodemographic Data Form (SDF), Young Parenting Inventory (YPI), Childhood Trauma Questionnaire (CTQ), and Addiction Profile Index (API) after the psychiatric examination. Results Most YPI subscales were significantly higher in the OUD group compared to the healthy control group (p < .05). A multivariate regression analyses model was statistically significant (x2 = 81,969, p < .001) with a Nagelkerke R2 value of 0.58. Family history of alcohol use disorder/substance use disorder (AUD/SUD), YPI belittling/criticizing (mother), YPI overprotective/anxious (mother), YPI pessimistic/fearful (mother), YPI restricted/emotionally inhibited (mother), and YPI pessimistic/fearful (father) were found to be independent predictors of the risk of developing OUD. Conclusion Critical, overprotective, and withdrawn parental attitudes, along with a family history of AUD/SUD, may predict OUD risk. This suggests the potential value of integrating parental-focused therapy into OUD treatment.

A novel Project ECHO curriculum on older adult pain management and opioid use disorder for outpatient clinicians

ABSTRACT Chronic pain, opioid use, and opioid use disorder (OUD) are increasingly common in older adults. Outpatient clinician education may improve outcomes. Our aim was to create and evaluate a novel curriculum for outpatient clinicians on older adult pain management, opioid prescribing, and OUD leveraging Project ECHO®, a model for delivering subspecialized medical knowledge to community outpatient clinicians via videoconferencing. The series is comprised of 8-hour-long sessions, each with an expert-led interactive lectures followed by participant-led case discussions. Topics include pain assessment & treatment, considerations in older adults (e.g. cognition, caregiver support), shared decision-making, behavioral health, and OUD diagnosis and treatment. Sixty-nine clinicians attended the series and completed the pre-series survey; 78% (n = 54) completed the post-series survey. Clinicians reported a significant increase in self-efficacy in 14/14 queried competencies and greater frequency of performing 7/10 practice behaviors regarding older adult pain management, opioid prescribing, and OUD management. The most liked curricular components were opportunities to learn with subspecialists and discussions with other community clinicians. Qualitative analysis suggests that clinicians may benefit from education on specific geriatrics-related content areas. This novel curriculum has potential to improve management of older adult chronic pain, opioid prescribing, and OUD in a virtual and scalable format.

Impact of an Education Module on the Knowledge and Attitudes of EM Physicians Towards Prescribing Buprenorphine/Naloxone for Opioid Use Disorder.

Opioid overdose continues to be a major cause of morbidity and mortality. Buprenorphine is an important treatment for patients with opioid-use disorder (OUD) and initiation in the emergency department (ED) has been shown to improve outcomes for these patients. Our objective was to assess the impact of a three-pronged education package on the knowledge and attitudes of emergency physicians towards using buprenorphine for treatment of OUD. Procedures/data/observations: We developed a three-pronged educational package including back- ground rationale for OUD treatment with buprenorphine, an evidence-based ED buprenorphine induction pathway and electronic medical record tools. This package was deployed to providers in an urban academic ED. A voluntary confidential pre-post survey was administered. Using a 6-point Likert Scale, participants were asked about their understanding, experience, and confidence with prescribing. A one-hour, three-pronged educational package changed the attitudes of emergency physicians towards buprenorphine treatment and demonstrated an increase in willingness and confidence to prescribe it for patients with OUD. Our findings suggest that healthcare entities that wish to boost buprenorphine prescribing can impact willingness and confidence to prescribe with a short education package.

Clinical characteristics associated with problematic pornography use among individuals seeking treatment for opioid use disorder.

Many jurisdictions are experiencing opioid epidemics. Opioid use disorder (OUD) often co-occurs with other psychiatric disorders including behavioral addictions like gambling disorder. However, little is known regarding the frequency and correlates of problematic pornography use (PPU) among people seeking treatment for OUD. Here we aimed to investigate PPU and its correlates in people seeking OUD treatment. From October 2018 to March 2020, 1,272 individuals seeking OUD treatment were screened for PPU by completing the Brief Pornography Screen (BPS), a 5-item instrument validated for assessing PPU. Self-reported data were used. Amongthe sample there were 707 (60%) males and 565 (40%) females. The mean age of participants was 37.9 ± 10.5 years (range 18-73), there were 707 (60%) males and 565 (40%) females, 9.9% (n = 126) exhibited low positive BPS scores (1 ≤ score < 4), and 4.5% of the sample (n = 57) screened positive for PPU (BPS score ≥4). Individuals screening positive for PPU versus negative were mostly male (77%), scored higher on measures of impulsivity in the domains of positive urgency, negative urgency, and sensation-seeking and demonstrated more psychopathology on measures of substance use,psychotic symptoms, emotional lability, depression/functioning and self-harm. A minority of individuals seeking treatment for OUD screened positive for PPU. Among individuals with OUD, those screening positive (versus negative) for PPU were more impulsive and experienced more psychiatric symptoms, suggesting the need for additional investigation and screening for and addressing PPU in people with OUD.

Buprenorphine for the Treatment of Military-related PTSD With Treatment-resistant Depression and Unexpected Benefit for Chronic Pain: Case Report.

The prevalence of treatment-resistant depression within global and military populations highlights the need for novel treatment approaches beyond monoamine neurotransmitter modulators. Buprenorphine (BUP), a semi-synthetic partial opioid agonist, is approved for the treatment of opioid use disorder and has shown promise in treating both depression and chronic pain. This case report discusses the use of transdermal BUP in treating a 36 year-old man with treatment-resistant depression with prominent anhedonia, military-related posttraumatic stress disorder, and chronic pain because of barosinusitis. Significant reductions in anxious and depressive symptoms, including in anhedonia, were observed with lasting effects. An unexpected finding was the discontinuation of prescribed hydromorphone for pain, suggesting the potential unique benefit of BUP in treating chronic pain and treatment resistant depression comorbidities. These findings implicate the diverse beneficial potential of BUP in psychiatric treatments for military populations.

Design and implementation of a Type-2 hybrid, prospective randomized trial of opioid agonist therapies integration into primary care clinics in Ukraine

IntroductionUkraine has high HIV prevalence, concentrated among people who inject drugs (PWID), mostly of opioids. Maintenance on opioid agonist therapies (OAT) is the most effective evidence-based treatment for opioid use disorder. As PWID experience high morbidity and mortality from preventable and treatable non-communicable diseases, international agencies recommend integrating OAT into primary care centers (PCC). MethodsA randomized, type-2 hybrid implementation trial was carried out to compare outcomes of OAT integration in PCC to OAT delivery at specialty treatment centers (STC) – standard-of-care. Tele-education supporting PCC providers in managing OAT, HIV, tuberculosis and non-communicable diseases along with pay-for-performance incentives were used to facilitate implementation. Consenting patients underwent 1:2 randomization to either STC or PCC. Quality health indicators (QHIs), a composite percentage of recommended primary and specialty services accessed by patients (blood/urine tests, cancer screenings, etc.), were defined as efficacy outcomes and were assessed by participant self-report at baseline and every 6 months over 24 months and electronic chart reviews after the completion of the follow-up. The primary outcome is defined as the difference in composite QHI scores at 24 months, in which a repeated measures likelihood-based mixed model with missing at random assumptions will be used. Providers at PCC completed surveys at baseline, 12 and 24 months to assess implementation outcomes including changes in stigma and attitudes towards OAT and PWID. Preliminary resultsAmong the 1459 participants allocated to STC (N = 509) or PCC (N = 950), there were no differences in clinical and demographic characteristics. Self-reported prevalences were available for HIV (42 %), HCV (57 %), and prior tuberculosis (17 %). Study retention at 6, 12, 18, and 24 months was as 91 %, 85 %, 80 %, and 74 %, respectively. ConclusionPWID have a high prevalence of medical comorbidities and integrating OAT into primary care settings has the potential to improve the health of PWID. Findings from this study can help guide implementation of integrated care in Ukraine and throughout similar low-resource, high-burden countries in the Eastern European and Central Asian region.

Barriers and Facilitators to Community Pharmacist-Provided Injectable Naltrexone for Formerly Incarcerated Individuals During Community Reentry in Wisconsin.

Medications for opioid use disorder (MOUD), including injectable naltrexone, are a key component in the treatment of opioid use disorder (OUD). These medications are especially important for individuals transitioning out of correctional facilities and back into their communities, as individuals receiving MOUD are 85% less likely to die due to drug overdose in the first month post-release and have a 32% lower risk of rearrest. Unfortunately, few formerly incarcerated individuals have access to MOUD upon reentry, incurring a 40-fold greater likelihood of overdose following release compared to the general population. While 84% of Wisconsin jails offering MOUD offer naltrexone, less than half provide linkage to community treatment for reentering individuals. In Wisconsin, community pharmacists have the authority to provide naltrexone injections. However, they have not been explored as a resource for improving access to this medication for formerly incarcerated individuals. As a first step, the goal of this study was to understand the barriers and facilitators impacting access to community pharmacist-provided injectable naltrexone for this patient population during community reentry period. The researcher conducted semi-structured interviews with 18 individuals representing five stakeholder groups. Deductive and inductive content analysis were used to identify barrier and facilitator categories across the five levels of the Socioecological Model. Overall, participants discussed factors at every level, and many barriers and facilitators confirmed findings from existing literature focused on MOUD access for formerly incarcerated individuals. Participants also identified factors more specific to community pharmacies, including 1) lack of interagency collaboration between pharmacists, prescribers, and correctional facilities and 2) lack of awareness of community pharmacist-provided MOUD services. Future research should explore interventions to address the barriers identified in this study and improve connections between community pharmacists and formerly incarcerated individuals. This work can help ensure that these individuals are given the chance to successfully reintegrate into society.

Pain, Substance Use Disorders, Mental Health, and Buprenorphine Treatment among Patients With and Without HIV

Treatment of opioid use disorder (OUD) with buprenorphine improves outcomes and mortality among people with HIV (PWH). However, engagement is low and is influenced by comorbidities. We examined the impact of patterns of co-occurring pain, substance use disorders (SUDs), and mental health diagnoses on buprenorphine initiation and retention in PWH. The Veterans Aging Cohort Study contained 7,875 patients (2,702 PWH and 5,173 without HIV) with new OUD clinical encounters (2008–2017). Buprenorphine initiation and retention were derived from prescription data. We identified patterns of co-occurring diagnoses (via ICD codes) and assessed the effects of class membership on both outcomes using latent class analysis and regression analyses. The mean age of patients was 55, 98% were male, 58% Black, 8% Hispanic, and only 8% initiated buprenorphine within 12 months of OUD diagnosis. Four classes of co-occurring diagnoses were identified: “Few Co-occurring Diagnoses” (42.3%); “Multiple Pain Conditions” (21.3%); “Pain + SUD” (18.4%) and “Pain + SUD + Mental Health” (18.0%). Patients in the “Pain + SUD” class and “Pain + SUD + Mental Health” class were significantly less likely to initiate buprenorphine and had 59% and 45% lower odds, respectively, of initiating buprenorphine compared with patients in the “Few Co-occurring Diagnoses” class; this effect did not vary by HIV status. Buprenorphine retention was not significantly associated with HIV status or class membership. However, Black Veterans were less likely to initiate or be retained in buprenorphine treatment. Higher comorbidity burden was negatively associated with buprenorphine initiation but not with retention. More research is warranted to determine other factors that may influence treatment retention.

Perceptions of extended-release buprenorphine among people who received medication for opioid use disorder in jail: a qualitative study

BackgroundIncarceration provides an opportunity for health interventions, including opioid use disorder (OUD) treatment and prevention of opioid-related overdoses post-release. All FDA-approved forms of medication for OUD (MOUD) treatment were mandated in several Massachusetts jails in 2019, with some jails offering extended-release buprenorphine (XR-Bup). Little is known about patient perspectives on and experiences with XR-Bup in carceral settings.MethodsWe conducted semi-structured interviews in 2022 with community-dwelling people who received MOUD during a recent incarceration in a Massachusetts jail. We asked participants about their experiences with and perspectives on XR-Bup while in jail. Qualitative data were double-coded deductively and reviewed inductively to identify emergent themes, which were structured using the Theoretical Framework of Acceptability (TFA).ResultsParticipants (n = 38) had a mean age of 41.5 years, were 86% male, 84% White, 24% Hispanic, and 95% continued to receive MOUD at the time of their interview, including 11% receiving XR-Bup. Participants who viewed XR-Bup favorably appreciated avoiding the taste of sublingual buprenorphine; avoiding procedural difficulties and indignities associated with daily dosing in carceral settings (e.g., mouth checks, stigmatizing treatment from correctional staff); avoiding daily reminders of their addiction; experiencing less withdrawal; having extra time for other activities, such as work; and reduction of diversion of MOUD within the jail setting. Participants who viewed XR-Bup less favorably preferred to maintain their daily dosing routine; liked daily time out of their housing unit; wanted to know what was “going into my body everyday”; and feared needles and adverse events. Participants also reported that jail clinicians used XR-Bup for patients who were previously caught diverting sublingual buprenorphine, suggesting limited patient participation in decision-making around XR-Bup initiation in some jails.ConclusionPeople who received MOUD in Massachusetts jails had both favorable and unfavorable views and experiences with XR-Bup. Understanding these preferences can inform protocols in jails that are considering implementation of XR-Bup treatment.

The impact of medication-assisted treatment for opioid use disorder on congestive heart failure outcomes

Congestive heart failure (CHF) and opioid use disorder (OUD) commonly coexist and are major contributors to high healthcare utilization in the United States. Medication assisted treatment (MAT; e.g., buprenorphine and methadone) reduces opioid-related mortality by about 50 %; yet little is known about how OUD treatment impacts CHF outcomes in patients with both CHF and OUD. We examined the impact of MAT (buprenorphine, methadone, and naltrexone) on CHF outcomes in patients diagnosed with OUD and CHF, and which MAT (buprenorphine or methadone) medication is associated with the fewest CHF outcomes. A retrospective cohort study of patients 18 years or older diagnosed with both CHF and OUD was conducted using Optum's de-identified Clinformatics® Data Mart Database. Multivariate logistic regression modeling was used to compared patients who were prescribed MAT to those who were not. The primary outcomes were CHF hospitalizations and CHF emergency department visits. No significant differences in the primary outcomes between the MAT and non-MAT cohorts were observed. In conclusion, the lack of association of MAT with negative CHF outcomes suggest that life-saving MAT can be safely used for OUD treatment in the CHF setting.

“I need as much support as I can get”: A qualitative study of young adult perspectives on family involvement in treatment for opioid use disorder

BackgroundOpioid use disorder (OUD) among young adults (YAs) continues to persist as a national health crisis. Best practice recommendations for YA OUD treatment highlight the importance of medication for OUD (MOUD) and family involvement across the treatment services continuum for better treatment retention and outcomes. Yet, concerned significant others (CSOs) such as family members, romantic partners, and family-of-choice members are not routinely involved in OUD and MOUD treatment for YAs. MethodWe used convenience sampling to recruit 25 YAs (ages 21 to 36) in treatment for OUD from two urban treatment centers. We discussed with YAs the identities of their CSOs and the dynamics of those relationships, their perspectives on CSO involvement in their OUD treatment, and the beliefs and attitudes they hold about family involvement in treatment and recovery. Thematic content analysis was deductive-dominant based on a semi-structured qualitative interview guide. Group consensus coding was followed by matrix analysis. ResultsWe identified five main themes: (1) YA and CSO relationships were supportive, evolving, and complex. (2) CSO support motivated treatment engagement and participation. (3) Only a small proportion of CSOs participated in treatment activities despite actively supporting treatment in other ways. (4) YAs experienced their CSOs as supportive of their treatment and recovery goals, including MOUD. (5) YAs believed family involvement is essential to treatment and many were unsatisfied with current family involvement in their care. ConclusionsIn this qualitative study of OUD treatment experiences among YAs, we learned that many YAs have CSOs who are invested in their treatment and recovery and yet are not routinely involved in treatment. Moreover, YAs often expressed family involvement is essential to OUD treatment, and many expressed a desire for greater family involvement in their own treatment. Clinical recommendations for relationship-oriented treatment are presented.

Barriers and facilitators to implementing treatment for opioid use disorder in community hospitals

IntroductionMethadone and buprenorphine are effective treatment for opioid use disorder (OUD), yet they are vastly under-utilized across US hospitals. To inform a national trial assessing the effectiveness of implementation strategies to increase adoption of an inpatient hospital-based opioid treatment (HBOT) model (NCT04921787), we explored barriers and facilitators to expanding medication for opioid use disorder (MOUD) within community hospitals across the United States. MethodsFrom November 2021 to March 2022, we used purposeful and snowball sampling to identify and interview participants involved in inpatient care of patients with OUD from twelve community hospitals. We conducted semi-structured interviews on providers' experiences and perspectives on current treatment approaches as well as potential influences on MOUD expansion in their hospitals. We used thematic analysis to identify key barriers and facilitators that could impact implementation of an HBOT model, and organized these findings based on the Consolidated Framework for Implementation Research (CFIR). ResultsFrom qualitative interviews with 57 participants (30 physicians, 7 pharmacists, 6 nurses, and 14 professionals involved in the care of patients with OUD), we identified key barriers and facilitators mapped to CFIR's internal and outer settings. The most salient inner setting domains included tension for change and relative priority, compatibility, available resources, organizational culture, access to knowledge and information, relational connections and communications, and information technology infrastructure. Outer setting domains included policies and laws, financing, and partnerships and connections. ConclusionsIdentifying potential barriers and facilitators can inform hospital-specific strategies to support implementation of HBOT. Implementation strategies that address barriers such as staff availability, knowledge, and attitudes may support increased HBOT adoption. On a broader scale, national policy changes such as increased financing and public reporting of quality metrics would address other barriers we identified and may also encourage hospitals to adopt HBOT models.

ADHD: prevalence and effect on opioid use disorder treatment outcome in a French sample of patients receiving medication for opioid use disorder—the influence of impulsivity as a mediating factor

BackgroundOpioid use disorder (OUD) poses a global health challenge, and despite medications for opioid use disorder (MOUD) and psychosocial interventions, relapse remains a significant concern. Comorbid psychiatric disorders, including attention deficit hyperactivity disorder (ADHD), are one of the major factors associated with poor OUD treatment outcome. We aimed to estimate the frequency of probable ADHD (in childhood and in adulthood) in patients with OUD; to assess the factors associated with this comorbidity; and to explore the factors that mediate the relationship between ADHD and OUD treatment outcome.MethodsWe conducted an observational study using a sample of 229 patients aged 18 years and older who were diagnosed with OUD and had received MOUD for at least six months. Participants were assessed through a structured interview and self-report questionnaires. Multivariate logistic regressions and a mediation analysis were performed.ResultsAlmost half of the participants reported probable ADHD in childhood, and ADHD persisted into adulthood among two-thirds of the patients. The factors associated with poor OUD treatment outcome included earlier onset of OUD, lower education, and greater impulsivity. There was no direct effect of probable ADHD in childhood on OUD treatment outcome, but there was an indirect effect through negative urgency, the tendency to respond impulsively to negatively connoted emotional experiences.ConclusionsThe findings suggest that ADHD symptoms, particularly impulsivity, may contribute to vulnerability in opioid use and play a crucial role in treatment outcomes for this population.Trial registration: ClinicalTrials identifier NCT01847729.

Self-Reported Illicitly Manufactured Fentanyl Use and Associated Health and Substance Use Risks in the United States, 2022

Objective Illicitly manufactured fentanyl (IMF) has emerged as a catalyst of the recent drug epidemic in the United States. To devise more targeted and effective prevention and treatment strategies, it is crucial to understand the demographics of the population who consumes IMF and their health and associated substance use risks. Therefore, this study explores the sociodemographic characteristics, health diagnoses, and drug injection practices of individuals reporting IMF use. Methods Data were derived from the 2022 National Survey on Drug Use Health, based on a nationally representative sample of non-institutionalized individuals aged 12 and older in the United States. Focusing on 306 adults who reported ever using IMF, we examined their sociodemographic characteristics, health diagnoses, and substance-related behaviors in comparison to adults with a drug use disorder who did not report IMF use, using logistic regression analyses. Results The majority of U.S. adults reporting IMF use were aged 35–64, male, non-Hispanic White, with a high school education or lower, never married, and had an annual household income below $40,000. Compared to adults with a drug use disorder who did not report IMF use, they were more likely to report heart conditions (AOR = 2.67, 95% CI = 1.29–5.54) and Hepatitis B or C (AOR = 8.35, 95% CI = 4.05–17.02). Nearly half of this group had an opioid use disorder (OUD) in the past year, and 65.7% (95% CI = 56.7–74.8) reported a history of injecting drugs. Conclusions To effectively curb the current drug epidemic, incorporating effective treatment for OUD and harm reduction strategies is crucial.

Medial prefrontal neuroplasticity during extended-release naltrexone treatment of opioid use disorder – a longitudinal structural magnetic resonance imaging study

Opioid use disorder (OUD) has been linked to macroscopic structural alterations in the brain. The monthly injectable, extended-release formulation of μ-opioid antagonist naltrexone (XR-NTX) is highly effective in reducing opioid craving and preventing opioid relapse. Here, we investigated the neuroanatomical effects of XR-NTX by examining changes in cortical thickness during treatment for OUD. Forty-seven OUD patients underwent structural magnetic resonance imaging and subjectively rated their opioid craving ≤1 day before (pre-treatment) and 11 ± 3 days after (on-treatment) the first XR-NTX injection. A sample of fifty-six non-OUD individuals completed a single imaging session and served as the comparison group. A publicly available [¹¹C]carfentanil positron emission tomography dataset was used to assess the relationship between changes in cortical thickness and μ-opioid receptor (MOR) binding potential across brain regions. We found that the thickness of the medial prefrontal and anterior cingulate cortices (mPFC/aCC; regions with high MOR binding potential) was comparable between the non-OUD individuals and the OUD patients at pre-treatment. However, among the OUD patients, mPFC/aCC thickness significantly decreased from pre-treatment to on-treatment. A greater reduction in mPFC/aCC thickness was associated with a greater reduction in opioid craving. Taken together, our study suggests XR-NTX-induced cortical thickness reduction in the mPFC/aCC regions in OUD patients. The reduction in thickness does not appear to indicate a restoration to the non-OUD level but rather reflects XR-NTX’s distinct therapeutic impact on an MOR-rich brain structure. Our findings highlight the neuroplastic effects of XR-NTX that may inform the development of novel OUD interventions.

Strategies to Improve Access to Care for Patients With Opioid Use Disorder.

Treatment of opioid use disorder (OUD) faces several challenges, including restricted access to medications, geographical and logistical barriers, and variability in treatment availability across different communities. This article outlines several strategies aimed at improving access to medications. Pharmacy-based care could potentially extend access to medications but would require regulatory changes to empower pharmacists. In addition, telemedicine has shown promise in improving access by mitigating geographic and transportation barriers. Mobile health clinics also offer a direct approach to delivering medication-based treatments to underserved communities. Furthermore, integrating OUD treatment into primary care settings could facilitate early detection and treatment. Policy changes have increased access to take-home medications and buprenorphine initiation at home. Community engagement would be crucial for tackling the social determinants of health to offer equitable care for patients. The implementation of these strategies has the potential to significantly enhance the accessibility and delivery of effective, timely and equitable treatment to patients with OUD.

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

BackgroundOpioid 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.MethodsThis 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.DiscussionMost 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.Trial RegistrationClinicalTrials.gov National Clinical Trials, NCT06087991.

Revisiting dezocine for opioid use disorder: A narrative review of its potential abuse liability.

Opioid use disorder (OUD) remains a serious public health problem. Opioid maintenance treatment is effective but under-utilized, hard to access under existing federal regulations, and, once patients achieve OUD stability, challenging to discontinue. Fewer than 2% of persons with OUD stop using opioids completely. There have been calls from public advocacy groups, governmental agencies, and public health officials for new treatments for OUD. Dezocine, a non-scheduled opioid previously used in the United States and currently widely prescribed in China for pain management, could be a candidate for a novel OUD treatment medication in the U.S. Nonetheless, to date, there have been no reviews of the clinical and preclinical literature detailing dezocine's abuse potential, a key consideration in assessing its clinical utility. There are no English language reports of human abuse, dependence, or overdose of dezocine, despite years of extensive clinical use. There are a few case reports of dezocine abuse in the Chinese literature, but there are no reports of overdose deaths. Dezocine is perceived as an opioid and is "liked" by opioid-experienced human and non-human primates, properties that are not dose-dependent and are mitigated by ceiling effects-higher doses do not result in more "liking." There is little withdrawal, spontaneous or precipitated, in humans, monkeys, rats, or mice treated chronically with dezocine alone. However, at some doses, dezocine can precipitate withdrawal in humans and monkeys dependent on other opioids. In rodents, dezocine reduces the severity of morphine withdrawal and the rewarding properties of other opioids. Although dezocine is reinforcing in humans and monkeys with prior or concurrent opioid use within a restricted dose range, there are only a few anecdotal reports of dezocine abuse despite of the long history of use in humans. Given the evidence of dezocine's limited abuse potential, it could be useful both as a treatment for OUD. However, in-depth studies would be required for dezocine to be re-considered for clinical use.

“I Really Didn’t See a Lot of This in My Training”: Family Medicine Residents’ and Recent Graduates’ Experiences of Training and Readiness to Deliver Treatment for Opioid Use Disorder

ABSTRACT Objective: Family physicians in Canada are often the first access point to health care for patients with opioid use disorders (OUDs). Patients receiving opioid agonist therapy from their family physician often have better treatment outcomes. This paper aims to evaluate the clinical and didactic training in the management of OUD for UofT family medicine trainees. Methods: This was a mixed methods study. Part 1 was an environmental scan of mandatory didactic and clinical teaching to family medicine residents across 15 teaching sites at the University of Toronto (UofT). Part 2 was a qualitative study assessing recent family medicine graduates’ comfort in treating OUD. The study was conducted at Canada’s largest postgraduate residency program. Family medicine postgraduate program directors and chief residents from all 15 teaching sites were invited to take part in the environmental scan. Using purposive sampling, 8 recent family medicine graduates were recruited to participate in qualitative interviews. Results: Of the 11 UofT teaching sites that responded, 3 had mandatory clinical rotations in addictions. Four reported no formal teaching during their weekly academic half days at their respective sites. Thematic analysis of interviews with recent UofT graduates highlighted 2 overarching themes: the structural marginalization of people with OUD and the invisibility of OUD within family practice. Conclusion: Our results highlight the significant variation in training experiences related to OUD and limited readiness to treat patients with OUD. Didactic and clinical training in the management of addictions, especially OUD, should be standardized across training sites in content and duration to ensure preparedness for practice. Objectif: Au Canada, les médecins de famille sont souvent le premier point d’accès aux soins de santé pour les patients souffrant de troubles liés à l’utilisation d’opioïdes (TUO). Les patients qui reçoivent un traitement par agoniste opioïde (TAO) de leur médecin de famille obtiennent souvent de meilleurs résultats thérapeutiques. Cet article vise à évaluer la formation clinique et didactique de gestion des TUO pour les stagiaires en médecine familiale de l’Université de Toronto. Méthodes: Il s’agit d’une étude à méthodes mixtes. La première partie consistait en une analyse de l’environnement de l’enseignement didactique et clinique obligatoire dispensé aux résidents de médecine familiale dans 15 sites d’enseignement de l’Université de Toronto (UofT). La deuxième partie était une étude qualitative évaluant l’aisance des récents diplômés en médecine familiale dans le traitement des TUO. L'étude a été menée dans le plus grand programme de résidence postuniversitaire du Canada. Les directeurs des programmes de formation postdoctorale en médecine familiale et les résidents en chef des 15 sites d’enseignement ont été invités à participer à l’analyse de l’environnement. À l’aide d’un échantillonnage descriptif, huit récents diplômés en médecine familiale ont été recrutés pour participer à des entrevues participatives. Résultats: Sur les 11 sites d’enseignement de l’UofT qui ont répondu, trois avaient des rotations obligatoires en cliniques d’addiction. Quatre d’entre eux ont déclaré n’avoir reçu aucun enseignement formel pendant leurs demi-journées d’enseignement hebdomadaires dans leurs sites respectifs. L’analyse thématique des entretiens avec les récents diplômés de l’UofT a mis en évidence deux thèmes principaux : la marginalisation structurelle des personnes souffrant de TUO et l’invisibilité de la TUO dans la pratique de la médecine familiale. Conclusion: Nos résultats mettent en évidence la variation significative des expériences de formation liées aux TUO et la préparation limitée au traitement des patients atteints de TUO. La formation didactique et clinique pour la gestion des addictions, en particulier des TUO, devrait être standardisée dans tous les sites de formation en termes de contenu et de durée afin d’assurer la préparation à la pratique.

Collaborating to heal addiction and mental health in primary care (CHAMP): A protocol for a hybrid type 2a trial

BackgroundThe gold-standard treatment for opioid use disorder (OUD) is medication for OUD (MOUD). However, less than a quarter of people with OUD initiate MOUD. Expanding the Collaborative Care Model (CoCM) to include primary care patients with OUD could improve access to and initiation of MOUD. This paper presents the methods and baseline sample characteristics of a Hybrid Type 2a trial comparing the effectiveness of CoCM for OUD and co-occurring mental health symptoms (MHS) to CoCM for MHS only. Method42 primary care clinics were cluster randomized and 254 primary care patients with OUD and elevated MHS were enrolled. Recruitment was terminated early by the Data and Safety Monitoring Board for futility. Participants completed research assessments at baseline, 3 months, and 6 months. The multiple primary outcomes were past-month number of days of nonmedical opioid use and SF12 Mental Health Component Summary (MCS) scores. ResultsMCS scores were over a standard deviation below the national mean (M = 34.5). Nearly half (47.6 %) of participants had previously overdosed in their lifetimes. Three quarters (76.0 %) were already being prescribed MOUD at baseline, only 30.4 % reported non-medical use of opioids, and only 33.9 % reported being bothered by opioid cravings. ConclusionThe unexpectedly high proportion of enrollees already prescribed MOUD at baseline indicates that most patients were in the maintenance rather than acute phase of treatment. Challenges identifying and enrolling patients in the acute phase of OUD treatment implies that intervention effectiveness will depend on its success preventing the discontinuation of MOUD rather than initiating MOUD.
