RESUMO

BACKGROUND: Persons with polysubstance use problems are at high suicide risk, which may complicate substance use treatment. The purpose of this study was to a) examine cross-sectional and longitudinal risk factors for suicidality among persons in methadone maintenance treatment who present with co-occurring cocaine use disorder and b) evaluate whether suicidality impacts substance use outcomes independently and differentially depending on treatment type (i.e. standard methadone care [SC] vs. contingency management plus standard care [CM + SC]). METHODS: Data come from five randomized controlled trials of CM conducted within methadone clinics (N = 562). Participants were categorized (mutually exclusive) as no history of suicidality (56.4%, n=317), past suicidal ideation (SI; 11%, n=62), recent SI (3.6%, n=20), or lifetime suicide attempt (29%, n=163). RESULTS: Suicidality groups differed by sex and baseline employment, income, trauma history, and psychosocial functioning. Suicide attempt history was positively associated with years of polysubstance use, prior drug treatments, and unintentional overdose history. Baseline psychological problem severity and emotional abuse history were associated with SI likelihood 12 weeks later. Past SI was associated with longer durations of abstinence than no suicidality. Unexpectedly, those with recent SI reported lower drug use severity at 12 week if they received SC compared to CM + SC. Effects were small to medium. CONCLUSIONS: Despite greater polysubstance use history, patients with suicide attempts did not show worse substance use outcomes than persons without suicidality. Patients with past SI fared better than those without suicidality on abstinence over 12 wk. Methadone clinics could be key points of entrance and continued services for suicide prevention.

RESUMO

Background: Treatment with methadone is effective in reducing heroin use, HIV risk, and death; however, not all patients respond to treatment. Better outcomes may emerge with personalized treatment based on factors that influence treatment courses. Objectives: To investigate psychosocial variables contributing to treatment response, using a comprehensive definition of treatment response. Methods: Seventy participants seeking treatment for heroin and cocaine addiction completed up to 40 weeks of daily methadone. At week 22, we administered a semi-structured interview for DSM-IV symptoms. We defined opioid treatment responders as people still enrolled at 22 weeks, not meeting past 30-day criteria for DSM-IV opioid abuse or dependence or DSM-5 opioid use disorder, and providing ≥75% opioid-negative urine samples in the 30 days prior to week 22. The same criteria were applied to assess cocaine treatment response. Results: Sample was 71% male, 41% White, and averaged 39.4 ± 7.9 years old. Opioid treatment response was more likely in participants who had been employed over the past 3 years (OR: 8.1, 95% CI: 1.2-55) and less likely in those who spent more time on hobbies (OR: 0.45, 95% CI: 0.23-0.88). Cocaine treatment response was more likely in participants who had a good relationship with their father (OR: 5.3, 95% CI: 1.2-24) and less likely if positive for hepatitis C (OR: 0.15, 95% CI: 0.03-0.75). Conclusions: Pretreatment characteristics differentially predict treatment response for heroin and cocaine use. Similar research in diverse patient groups may aid in the development of personalized treatment combining biologic treatment with targeted psychosocial interventions.

RESUMO

Pharmacotherapy for opioid addiction with methadone, buprenorphine, and naltrexone has proven efficacy in reducing illicit opioid use. These treatments are under-utilized among opioid-addicted individuals on parole, probation, or in drug courts. This paper examines the peer-reviewed literature on the effectiveness of pharmacotherapy for opioid addiction of adults under community-based criminal justice supervision in the US. Compared to general populations, there are relatively few papers addressing the separate impact of pharmacotherapy on individuals under community supervision. Tentative conclusions can be drawn from the extant literature. Reasonable evidence exists that illicit opioid use and self-reported criminal behaviour decline after treatment entry, and that these outcomes are as favourable among individuals under criminal justice supervision as the general treatment population. Surprisingly, there is no conclusive evidence regarding the extent to which pharmacotherapy impacts the likelihood of arrest and incarceration among individuals under supervision. However, given the proven efficacy of these three medications in reducing illicit opioid use and the evidence that, in the general population, methadone and buprenorphine treatment are associated with reduction in overdose mortality, the use of all three pharmacotherapies among patients under criminal justice supervision should be expanded while more data are collected on their impact on arrest and incarceration.

RESUMO

BACKGROUND: Opioid dependence is a major health concern across the world and does also occur in adolescents. While opioid substitution treatment (OST) has been thoroughly evaluated in adult populations, very few studies have examined its use in adolescents. There are concerns that OST is underutilised in adolescents with heroin dependence. We sought to measure changes in drug use among adolescents receiving OST and also to examine treatment attrition during the first 12 months of this treatment. METHODS: We included all heroin dependent patients aged under 18.5 years commencing OST at one outpatient multidisciplinary adolescent addiction treatment service in Dublin, Ireland. Psycho-social needs were also addressed during treatment. Drug use was monitored by twice weekly urine drugs screens (UDS). Change in the proportion of UDS negative for heroin was examined using the Wilcoxon signed rank test. Attrition was explored via a Cox Regression multivariate analysis. RESULTS: OST was commenced by 120 patients (51% female and mean age 17.3 years). Among the 39 patients who persisted with OST until month 12, heroin abstinence was 21% (95% confidence interval [CI] = 9-36%) at month three and it was 46% (95% CI = 30-63%) at month 12. Heroin use declined significantly from baseline to month three (p < 0.001) and from month three to month 12 (p = 0.01). Use of other drugs did not change significantly. People using cocaine during month 12 were more likely to be also using heroin (p = 0.02). Unplanned exit occurred in 25% patients by 120 days. The independent predictors of attrition were having children, single parent family of origin, not being in an intimate relationship with another heroin user and evidence of cocaine use just before treatment entry. CONCLUSIONS: We found that heroin dependent adolescent patients achieved significant reductions in heroin use within three months of starting OST and this improved further after a year of treatment, about half being heroin abstinent at that stage. Patient drop out from treatment remains a challenge, as it is in adults. Cocaine use before and during treatment may be a negative prognostic factor.

RESUMO

BACKGROUND: Treatment for opioid dependence in Ireland is provided predominantly by general practitioners (GP) who have undergone additional training in opioid agonist treatment (OAT) and substance misuse. The National Methadone Treatment Programme (MTP) was introduced in 1998, and was designed to treat the opioid dependent population and to regulate the prescribing regimes at the time. The past two decades have seen the increased prescribing of methadone in primary care and changes in type of opioid abused, in particular, the increased use of over the counter (OTC) and prescription medications. Despite the scaling up of OAT in Ireland, drug related deaths however have increased and waiting lists for treatment exist in some areas outside the capital, Dublin. Two previous MTP reviews have made recommendations aimed at improving and scaling up of OAT in Ireland. This study updates these recommendations and is the first time that a group of national experts have engaged in structured research to identify barriers to OAT delivery in Ireland. The aim was to explore the views of national statutory and non-statutory stakeholders and experts on current barriers within the MTP and broader OAT delivery structures in order to inform their future design and implementation. METHODS: A single focus group with a chosen group of national key stakeholders and experts with a broad range of expertise (clinical, addiction and social inclusion management, harm reduction, homelessness, specialist GPs, academics) (n = 11) was conducted. The group included national representation from the areas of drug treatment delivery, service design, policy and practice in Ireland. RESULTS: Four themes emerged from the narrative analysis, and centred on OAT Choices and Patient Characteristics; Systemic Barriers to Optimal OAT Service Provision; GP Training and Registration in the MTP, and Solutions and Models of Good Practice: Using What You Have. CONCLUSION: The study identified a series of improvement strategies which could reduce barriers to access and the stigma associated with OAT, optimise therapeutic choices, enhance interagency care planning within the MTP, utilise the strengths of community pharmacy and nurse prescribers, and recruit and support methadone prescribing GPs in Ireland.

RESUMO

Under the leadership of Drs. Vincent P. Dole, Marie Nyswander, and Mary Jeanne Kreek, in collaboration with the psychologist, Norman Gordon and sociologist, Herman Joseph at The Rockefeller University beginning in the 1960s, the first medical treatment for heroin addiction was developed. Drs. Dole, Nyswander and Kreek also developed the first hypothesis of opiate addiction as a metabolic disease. This biological revolution challenged beliefs about addiction, spurred further research and challenged legal positions of the judiciary and the broader criminal justice system (Dole & Nyswander, 1967 ).

RESUMO

BACKGROUND: Opioid misuse and dependence is a global issue with a huge negative impact. In Malaysia, heroin is still the main illicit drug used, and methadone maintenance treatment (MMT) has been used since 2005. OBJECTIVE: To evaluate the effectiveness of MMT. METHODS: This was a cross-sectional study conducted in 103 treatment centers between October and December 2014 using a set of standard questionnaires. Data were analyzed using SPSS Statistics 20. RESULTS: There were 3254 respondents (93.6% response rate); of these 17.5% (n = 570) transferred to another treatment center, 8.6% (n = 280) died, 29.2% (n = 950) defaulted, and 7.6% (n = 247) were terminated for various reasons. Hence, 1233 (37%) respondents' baseline and follow-up data were further analyzed. Respondents had a mean age of 39.2 years old and were mainly male, Malay, Muslim, married (51.1%, n = 617), and currently employed. Few showed viral seroconversion after they started MMT (HIV: 0.5%, n = 6; Hepatitis B: 0.3%, n = 4; Hepatitis C: 2.7%, n = 29). There were significant reductions in opioid use, HIV risk-taking score (p < 0.01), social functioning (p < 0.01), crime (p < 0.01), and health (p < 0.01). However, there were significant improvements in quality of life in the physical, psychological, social, and environmental domains. Factors associated with change were being married, employed, consuming alcohol, and high criminality at baseline. Lower methadone dosage was significantly associated with improvements in the physical, psychological, and environmental domains. Conclusion/Importance: The MMT program was found to be successful; hence, it should be expanded.

RESUMO

This article concentrates on methadone maintenance as a normalizer for the impairments of opioid addiction, and the misunderstandings of it as a substitute for heroin that continues an opiate addiction. Methadone treatment was developed by Drs. Dole, Nyswander, and Kreek. Their cutting-edge theory transformed the way that opioid addiction is perceived and their work changed methadone from a narcotic to withdraw addicts to a medication that is a maintenance normalizer for a chronic condition. Their extensive research involved the physiological and sociological normalizing effects of methadone and medical safety of the medication (Dole & Nyswander, 1967).

RESUMO

BACKGROUND: In Vietnam, like many countries in Southeast Asia, the commonly used approach of center-based compulsory drug treatment (CCT) has been criticized on human rights ground. Meanwhile, community-based voluntary methadone maintenance treatment (MMT) has been implemented for nearly a decade with promising results. Reform-minded leaders have been seeking empirical evidence of the costs and effectiveness associated with these two main treatment modalities. Conducting evaluations of these treatments, especially where randomization is not ethical, presents challenges. The aim of this paper is to discuss political challenges and methodological issues when conducting cost-effectiveness studies within the context of a non-democratic Southeast Asian country. METHODS: A retrospective analysis of the political and scientific challenges that were experienced in the study design, sample size determination, government approval and ethics approvals, participant recruitment, data collection, and determination of sources, and quantification of cost and effectiveness data was undertaken. As a consequence of the non-randomized design, analysis of patient characteristics for both treatment types was undertaken to identify the magnitude of baseline group differences. Concordance between self-reported heroin use and urine drug testing was undertaken to determine the reliability of self-report data in a politically challenging environment. RESULTS: We demonstrate that conducting research around compulsory treatment in a non-democratic society is feasible, yet it is politically challenging and requires navigation between science and politics. We also demonstrate that engagement with the government decision makers in the research conception, implementation, and dissemination of the results increases the likelihood of research evidence being considered for change in a contentious drug policy area. CONCLUSIONS: Local empirical evidence on the comparative cost-effectiveness of CCT and MMT in a Southeast Asian setting is critical to consideration of more holistic, humane, and effective drug-dependence treatment approaches, but the garnering of such evidence is very challenging.

RESUMO

BACKGROUND: Benzodiazepine use disorders are a common clinical problem among methadone maintenance treatment patients and have adverse effects on clinical outcomes. OBJECTIVES: To evaluate gabapentin for the outpatient treatment of benzodiazepine abuse or dependence in methadone maintenance patients. METHODS: Participants (n = 19) using benzodiazepines at least 4 days per week were enrolled into an 8-week randomized double-blind placebo-controlled outpatient pilot trial. All participants received a manual-guided supportive psychotherapy aimed to promote abstinence. Study medication was titrated over a 2-week period to a maximum dose of gabapentin 1200 mg or placebo three times a day. Benzodiazepine use was assessed using urine toxicology confirmed self-report. Benzodiazepines were not provided as part of study participation; participants were provided guidance to gradually reduce benzodiazepine intake. RESULTS: Sixteen participants had post-randomization data for analysis. Retention at week eight was 50%. The mean dose of gabapentin achieved by titration was 2666 mg/day (SD = ± 1446). There were no significant between group differences on benzodiazepine use outcomes (amount benzodiazepine per day [Mann-Whitney U = 27, p = 0.745], abstinent days per week [U = 28, p = 0.811]) and Clinical Instrument Withdrawal Assessment (CIWA)-benzodiazepines scale (U = 29.0, p = 0.913). One participant in the gabapentin group discontinued study medication because of peripheral edema. Two participants in the placebo group requested admission for inpatient detoxification treatment. CONCLUSION: In outpatient methadone-maintained patients with benzodiazepine use disorder, gabapentin did significantly decrease benzodiazepine use relative to placebo. The small sample recruited for this trial may have limited the ability to detect a group difference.

RESUMO

UNLABELLED: The safety of varenicline in the treatment of tobacco dependence has been questioned, in psychiatric patients. However, most published studies have not included psychiatric patients. OBJECTIVE: Assess the safety of varenicline for smoking cessation in patients with psychiatric disorders. METHODS: This is a prospective, longitudinal, multicenter study. The sample is composed of three groups (patients with psychotic disorder, patients with alcohol dependence disorder and patients addicts in methadone maintenance treatment). Patients were recruited consecutively between September 2008 and June 2009 from 11 centers. All patients received a standardized smoking cessation program with varenicline and psychological support. Adverse events of the drug were monitored at weeks 1, 2, 4, 6, 8, and 12 of treatment. Bivariate analysis has been used. RESULTS: None of the 90 patients included, presented a serious adverse event. The most frequent adverse effect was dry mouth (28.9%), followed by the presence of flatulence (27.8%), abnormal dreams (27.8%), and nausea (22%), especially between weeks 2 and 6 of treatment. None of the patients referred intense suicidal ideation, although two referred to moderate suicidal ideation, which was solved in one case and in the other, treatment was discontinued. Four participants (4.4%) abandoned treatment because of gastrointestinal symptoms. The initial dose of varenicline was reduced in 25% of patients during the study. CONCLUSIONS: Gastrointestinal adverse events are the most incident in this sample of psychiatric patients and no exacerbation of psychiatric symptoms was detected, thus indicating a good safety record for varenicline use for smoking cessation in psychiatric patients.

RESUMO

BACKGROUND: Childhood sexual abuse (CSA) is often considered an important distal factor in HIV sexual risk behaviors; however, there are limited and mixed findings regarding this relationship among women experiencing substance use problems. In addition, research with this population of women has yet to examine differences in observed CSA-HIV sexual risk behaviors relationships by CSA type and characteristics. OBJECTIVES: This study examines relationships between CSA coding, type, and characteristics and HIV sexual risk behaviors with main intimate partners among a random sample of 390 women in methadone treatment in New York City who completed individual interviews with trained female interviewers. RESULTS: Findings from logistic regression analyses indicate that CSA predicts substance use with sexual activity, with variations by CSA coding, type, and characteristics; however, the role of CSA is more limited than expected. Having a main partner with HIV risk mediates some relationships between CSA and drinking four or more drinks prior to sex. Intimate partner violence is the most consistent predictor of sexual risk behaviors. Other salient factors include polysubstance use, depression, social support, recent incarceration, relationship characteristics, and HIV status. CONCLUSIONS/IMPORTANCE: This study contributes to understanding of relationships between CSA and HIV sexual risk behaviors and key correlates associated with HIV sexual risk behaviors among women in methadone treatment. It also highlights the complexity of measuring CSA and its association with sexual risk behaviors and the importance of comprehensive approaches to HIV prevention that address psychological, relational, situational, and substance use experiences associated with sexual risk behaviors among this population.

RESUMO

A common treatment intervention for heroin addiction is methadone maintenance. In recent years a wider perspective has been adapted to understand and evaluate addiction through quality of life. This article examines quality of life conditions of 170 male former Soviet Union and Israeli origin drug users in methadone maintenance and provides an understanding of conditions linked to the World Health Organization Quality of Life project's best available techniques reference document. Having a partner or spouse and less chronic illness are positive factors affecting quality of life regardless of country of origin. Israeli born drug users reported better quality of life based on their psychological health and environment domain responses; no difference was found for the physical health and social relationship domains of the Israeli and former Soviet Union origin males. Because heroin addiction is a chronic and relapsing illness, one of the goals of methadone maintenance is to address patients' health status from a broad perspective. Based on clinical observations, the treatment of special populations may be enhanced if their particular needs are considered and met. Quality of life factors are relevant for assessing high risk groups, including those from different ethnic origins, in poor physical and psychological health, their treatment and personal adjustment, and their service personnel training needs.

RESUMO

The monitoring of essential and toxic elements in patients with Opioid Use Disorder (OUD) undergoing methadone treatment (MT) is important, and there is limited previous research on the urinary levels of these elements in MT patients. Therefore, the present study aimed to analyze certain elements in the context of methadone treatment compared to a healthy group. In this study, patients with opioid use disorder undergoing MT (n = 67) were compared with a healthy group of companions (n = 62) in terms of urinary concentrations of some essential elements (selenium (Se), zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), calcium (Ca)) and toxic elements (lead (Pb), cadmium (Cd), arsenic (As), and chromium (Cr)). Urine samples were prepared using the acid digestion method with a mixture of nitric acid and perchloric acid and assessed using the ICP-MS method. Our results showed that the two groups had no significant differences in terms of gender, education level, occupation, and smoking status. Urinary concentrations of Se, Cu, and Fe levels were significantly lower in the MT group compared to the healthy subjects. However, the concentrations of Pb, Cd, As, Mn, Cr, and Ca in the MT group were higher than in the healthy group (p < 0.05). No significant difference was established between the levels of Zn in the two groups (p = 0.232). The results of regression analysis revealed that the differences between the concentration levels of all metals (except Zn) between two groups were still remained significant after adjusting for all variables (p < 0.05). The data obtained in the current study showed lower urinary concentrations of some essential elements and higher levels of some toxic elements in the MT group compared to the healthy subjects. These findings should be incorporated into harm-reduction interventions.

RESUMO

AIM: To assess the effectiveness and cost-effectiveness of buprenorphine and methadone treatment in the U.S. if exemptions expanding coverage for substance use disorder services via telehealth and allowing opioid treatment programs to supply a greater number of take-home doses of medications for opioid use disorder (OUD) continue (Notice of Proposed Rule Making, NPRM). DESIGN SETTING AND PARTICIPANTS: Model-based analysis of buprenorphine and methadone treatment for a cohort of 100,000 individuals with OUD, varying treatment retention and overdose risk among individuals receiving and not receiving methadone treatment compared to the status quo (no NPRM). INTERVENTION: Buprenorphine and methadone treatment under NPRM. MEASUREMENTS: Fatal and nonfatal overdoses and deaths over five years, discounted lifetime per person QALYs and costs. FINDINGS: For buprenorphine treatment under the status quo, 1.21 QALYs are gained at a cost of $19,200/QALY gained compared to no treatment; with 20% higher treatment retention, 1.28 QALYs are gained at a cost of $17,900/QALY gained compared to no treatment, and the strategy dominates the status quo. For methadone treatment under the status quo, 1.11 QALYs are gained at a cost of $17,900/QALY gained compared to no treatment. In all scenarios, methadone provision cost less than $20,000/QALY gained compared to no treatment, and less than $50,000/QALY gained compared to status quo methadone treatment. CONCLUSIONS: Buprenorphine and methadone OUD treatment under NPRM are likely to be effective and cost-effective. Increases in overdose risk with take-home methadone would reduce health benefits. Clinical and technological strategies could mitigate this risk.

RESUMO

INTRODUCTION: People seeking treatment at opioid treatment programs (OTPs) can face admission delays. Interim methadone (IM) treatment, an effective approach to expedite admissions when programs lack sufficient counseling staff, has been seldom implemented. A study of implementation facilitation to spur the use of IM was conducted among six OTPs and their state opioid treatment authorities (SOTAs) in four US states. Between study recruitment and launch, organizational changes at three OTPs eliminated their need for IM. Two OTPs' requests to their states to provide IM (one prior to study launch and one following launch) were deferred by the states due to internal issues that required resolution to comply with federal IM regulations. During the study, another OTP's delays resolved, and one OTP streamlined its admissions procedures. METHODS: Virtual interviews were conducted with 16 OTP staff and SOTAs from six OTPs in four US states following their participation in the parent study. Interviews focused on the feasibility and acceptability of the implementation intervention for IM. We analyzed data using a constant comparative approach. RESULTS: Two overarching themes emerged from the qualitative data with respect to the role that organizational culture plays in OTP staff views of efforts to implement interim methadone: (1) the contrasting views of interim methadone based on whether staff adopt a traditional treatment vs. harm reduction philosophy and (2) the importance of reconciling these philosophies in addressing the culture shift that would accompany the process of implementing IM. CONCLUSIONS: Organizational treatment philosophy and program culture emerged as important factors determining the OTPs' staff's willingness to adopt new approaches to expedite admissions. Participants noted a tension between traditional treatment and harm reduction philosophies that impacted their views of IM, in part based on when they entered the drug treatment field. While understanding and addressing treatment philosophy and organizational culture and willingness to change is of importance when implementing new approaches in OTPs, leadership at the state and OTP level are powerful drivers of change.

RESUMO

INTRODUCTION: Following the March 2020 federal declaration of a COVID-19 public health emergency, in line with recommendations for social distancing and decreased congregation, federal agencies issued sweeping regulation changes to facilitate access to medications for opioid use disorder (MOUD) treatment. These changes allowed patients new to treatment to receive multiple days of take-home medications (THM) and to use remote technology for treatment encounters-allowances that previously had been reserved exclusively for "stable" patients who met minimum adherence and time-in-treatment criteria. The impact of these changes on low-income, minoritized patients (frequently the largest recipients of opioid treatment program [OTP]-based addiction care), however, is not well characterized. We aimed to explore the experiences of patients who were enrolled in treatment prior to COVID-19 OTP regulation changes, with the goal of understanding patients' perceptions of the impact of these changes on treatment. METHODS: This study included semistructured, qualitative interviews with 28 patients. We used a purposeful sampling method to recruit individuals who were active in treatment just before COVID-19-related policy changes went into effect, and who were still in treatment several months later. To ensure a diverse array of perspectives, we interviewed individuals who either had or had not experienced challenges with methadone medication adherence from 3/24/21 to 6/8/21, approximately 12-15 months following the onset of COVID-19. Interviews were transcribed and coded using thematic analysis. RESULTS: Participants were majority male (57 %), Black/African American (57 %), with a mean age of 50.1 (SD = 9.3). Fifty percent received THM prior to COVID-19, which increased to 93 % during the pandemic. COVID-19 program changes had mixed effects on treatment and recovery experiences. Themes identified convenience, safety, and employment as reasons for preferring THM. Challenges included difficulty with managing/storing medications, experiencing isolation, and concern about relapse. Furthermore, some participants reported that telebehavioral health encounters felt less personal. CONCLUSIONS: Policymakers should consider patients' perspectives to foster a more patient-centered approach to methadone dosing that is safe, flexible, and accommodating to a diverse array of patients' needs. Additionally, technical support should be provided to OTPs to ensure interpersonal connections are maintained in the patient-provider relationship beyond the pandemic.

RESUMO

BACKGROUND: Although medications for opioid use disorder (MOUD) are efficacious treatments for opioid use disorder, retention remains low. Peer recovery specialists (PRSs), individuals with lived substance use and recovery experience, may be particularly well-suited to support patients receiving MOUD. While PRSs are rarely trained in evidence-based behavioral interventions other than motivational interviewing, preliminary evidence suggests that peers can deliver brief behavioral interventions, such as behavioral activation, with efficacy and fidelity. This qualitative study sought to explore patient perspectives on receiving an adapted PRS-delivered behavioral activation intervention (Peer Activate) to support patients receiving methadone treatment. METHODS: The sample (N = 26) included patients recently starting or demonstrating challenges with adherence at a community-based methadone treatment program who received the Peer Activate intervention in a pilot trial. Participants were invited to participate in in-depth, semi-structured interviews at study completion or discontinuation, assessing perceived acceptability and feasibility of Peer Activate, and stigma-related barriers. Interview transcripts were coded using codebook/template thematic analysis. RESULTS: Analysis revealed the importance of two areas to promote intervention acceptability: 1) connection with intervention content and skill building, and 2) valued PRS-specific qualities. Intervention flexibility was found to promote feasibility of the intervention in the context of chaotic and challenging life circumstances. Additionally, participants described stigma towards substance use and methadone treatment as potential barriers to engaging in methadone treatment. CONCLUSION: Results support the acceptability and feasibility to patients of this PRS-delivered behavioral activation intervention in the context of outpatient MOUD treatment among a low-income, majority racially minoritized patient population. Future intervention adaptation and implementation should focus on incorporating content related to relationships and interpersonal skills; balancing behavioral intervention content with system navigation support; maintaining flexibility; and further investigation of the impact of individual PRS attributes, including shared lived experiences, on intervention acceptability and shifts in stigma.

RESUMO

BACKGROUND: During the COVID-19 pandemic, federal regulations in the USA for methadone treatment of opioid use disorder (OUD) were temporarily revised to reduce clinic crowding and promote access to treatment. METHODS: As part of a study seeking to implement interim methadone without routine counseling to hasten treatment access in Opioid Treatment Programs with admission delays, semi-structured qualitative interviews were conducted via Zoom with participating staff (N = 11) in six OTPs and their State Opioid Treatment Authorities (SOTAs; N = 5) responsible for overseeing the OTPs' federal regulatory compliance. Participants discussed their views on the response of OTPs in their states to the pandemic and the impact of the COVID-related regulatory flexibilities on staff, established patients, and new program applicants. Interviews were audio recorded, transcribed, and a content analysis was conducted using ATLAS.ti. RESULTS: All SOTAs requested the blanket take-home exemption and supported the use of telehealth for counseling. Participants noted that these changes were more beneficial for established patients than program applicants. Established patients were able to obtain a greater number of take-homes and attend individual counseling remotely. Patients with limited resources had greater difficulty or were unable to access remote counseling. The convenience of intake through telehealth did not extend to new program applicants because the admission physical exam requirement was not waived. CONCLUSIONS: The experienced reflections of SOTAs and OTP providers on methadone practice changes during the COVID-19 pandemic offer insights on SAMHSA's proposed revisions to its OTP regulations.

RESUMO

Background: This study aimed to investigate the prevalence of domestic violence (DV) against women who are undergoing methadone maintenance therapy (MMT) and its related risk factors. Methods: This case-control study was conducted on 195 women who were under MMT and a control group consisting of 195 women who were not under it in the city of Zahedan from 22 May to 1 December 2019. Data were collected using a questionnaire for the measurement of violence against women and a sociodemographic questionnaire. In order to analyze the data, the t test, analysis of variance (ANOVA), Pearson's correlation, and multiple regression analysis were used. Findings: In the case group, 67.2% of participants had experienced DV during the past year. In the control group, the prevalence was 78.5%. The rate of more than one occasion of DV was significantly higher in the group who were under MMT (P<0.05). The most common type of violence was mental abuse. Physical, sexual, and economic abuses were in the next ranks. Important predictors of DV, in order of importance, were: the women's low educational level, smoking, income level, and polygamy (P<0.05). Conclusion: MMT is not a risk factor for DV. It seems that the rate of DV against women in Zahedan is very high. The prevalence of recurrent DV in women under MMT was higher than in the general population.
