Assessing predictors of adequate individual buprenorphine maintenance dosage for the treatment of opioid use disorder: Listening to the patient. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 130:104519. [PMID: 39024687 DOI: 10.1016/j.drugpo.2024.104519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 05/27/2024] [Accepted: 07/02/2024] [Indexed: 07/20/2024]
Abstract
OBJECTIVE Dose optimization plays a key role in determining clinical outcomes in patients on opioid agonist treatment (OAT). The objective of this study was to identify the variables independently associated with buprenorphine/naloxone (B/N) dose adequacy in patients with opiate use disorder (OUD). METHOD Cross-sectional study of a convenience sample of patients with OUD treated with B/N (n = 315) in four regions in Spain. The Opiate Dosage Adequacy Scale (ODAS) was used to determine B/N dose adequacy. The ODAS evaluate the six components of the "dose adequacy" construct, as follows: continued use of heroin; narcotic blockade or crossed tolerance; objective opioid withdrawal symptoms (OWS); subjective OWS; craving for heroin; and overmedication. A binomial logistic regression analysis was performed to identify the variables associated with the condition "ODAS Adequate B/N dose". Participants completed a battery of instruments to assess sociodemographic, substance use, clinical, and treatment variables. RESULTS The B/N dose was considered adequate in 231 of the 315 participants (73.3 %). Two variables, satisfaction with B/N as a medication (OR=5.764, 95 % CI=2.211-15.030) and patient-perceived participation in B/N dose decisions (OR=1.790, 95 % CI=1221-2623), were independently, significantly, and positively associated with the "ODAS Adequate B/N dose" condition. While the severity of heroin dependence was significantly associated with buprenorphine dose adequacy in the bivariate analyses, significance was lost in the full regression model. CONCLUSION Satisfaction with B/N as a medication and patient-perceived involvement in the dose decision are associated with clinician-assessed dose adequacy. In the context of good clinical practice, it is important to take into account both of these variables to individualize the prescribed dose through a shared decision-making process.

JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2024; 163:209361. [PMID: 38703949 DOI: 10.1016/j.josat.2024.209361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 03/04/2024] [Accepted: 03/27/2024] [Indexed: 05/06/2024]
Abstract
INTRODUCTION Medications for opioid use disorder (MOUD) including methadone (MMT), buprenorphine (BUP), and naltrexone (NTX) are safe and effective. However, there are significant negative perceptions surrounding MOUD, creating barriers to uptake. While research on MOUD stigma has largely focused on provider and patient experiences, fewer studies have explored MOUD perceptions among the general public. Given that MOUD stigma expressed by social ties surrounding individuals with OUD can influence treatment choices, we assessed MOUD perceptions among U.S. adults to determine how beliefs impacted treatment preference. We further explored how MOUD perceptions may be amplified among racialized groups with histories of experiencing drug-related discrimination. METHODS The study collected survey data from a diverse sample of U.S. adults (n = 1508) between October 2020 and January 2021. The survey measured knowledge of MOUD and non-medication treatments, relative agreement with common MOUD perceptions, and treatment preferences. Multinomial logistic regression analysis tested associations with treatment preference, stratified by race/ethnicity. RESULTS Descriptive results indicated that across groups, many respondents (66.8 %) had knowledge of MOUD, but believed MOUD was a "substitute" for opioids and had some degree of concern about misuse. Multivariable results showed knowledge of non-medication treatments was positively associated with MOUD preference among White (MMT OR = 3.16, 95 % CI = 1.35-7.39; BUP OR = 2.69, CI = 1.11-6.47), Black (MMT OR = 3.91, CI = 1.58-9.69), and Latino/a (MMT OR = 5.12, CI = 1.99-13.2; BUP OR = 3.85, CI = 1.5-9.87; NTX OR = 4.51, CI = 1.44-14.06) respondents. Among White respondents, we identified positive associations between MOUD experience and buprenorphine preference (OR = 4.33, CI = 1.17-16.06); non-medication treatment experience and preference for buprenorphine (OR = 2.86, CI = 1.03-7.94) and naltrexone (OR = 3.17, CI = 1.08-9.28). Concerns around misuse of methadone were negatively associated with methadone preference among White (OR = 0.65, CI = 0.43-0.98) and Latino/a (OR = 0.49, CI = 0.34-0.7), and concerns around misuse of buprenorphine was negatively associated with preference for MOUD among White (MMT OR = 0.62, CI = 0.39-0.99; BUP OR = 0.48, CI = 0.3-0.77; NTX OR = 0.6, CI = 0.36-0.99) and Latino/a (BUP OR = 0.59, CI = 0.39-0.89) respondents. CONCLUSIONS This analysis offers critical insights into treatment perceptions beyond the patient population, finding that negative beliefs around MOUD are common and negatively associated with preferences for medication-based treatment. These findings highlight implications for public support of evidence-based treatment and lay the groundwork for future interventions addressing public stigma toward MOUD.

Impact of jail-based methadone or buprenorphine treatment on non-fatal opioid overdose after incarceration. Drug Alcohol Depend 2024; 259:111274. [PMID: 38643529 PMCID: PMC11111329 DOI: 10.1016/j.drugalcdep.2024.111274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 02/13/2024] [Accepted: 03/18/2024] [Indexed: 04/23/2024]
Abstract
BACKGROUND Non-fatal overdose is a leading predictor of subsequent fatal overdose. For individuals who are incarcerated, the risk of experiencing an overdose is highest when transitioning from a correctional setting to the community. We assessed if enrollment in jail-based medications for opioid use disorder (MOUD) is associated with lower risk of non-fatal opioid overdoses after jail release among individuals with opioid use disorder (OUD). METHODS This was a retrospective, observational cohort study of adults with OUD who were incarcerated in New York City jails and received MOUD or did not receive any MOUD (out-of-treatment) within the last three days before release to the community in 2011-2017. The outcome was the first non-fatal opioid overdose emergency department (ED) visit within 1 year of jail release during 2011-2017. Covariates included demographic, clinical, incarceration-related, and other characteristics. We performed multivariable cause-specific Cox proportional hazards regression analysis to compare the risk of non-fatal opioid overdose ED visits within 1 year after jail release between groups. RESULTS MOUD group included 8660 individuals with 17,119 incarcerations; out-of-treatment group included 10,163 individuals with 14,263 incarcerations. Controlling for covariates and accounting for competing risks, in-jail MOUD was associated with lower non-fatal opioid overdose risk within 14 days after jail release (adjusted HR=0.49, 95% confidence interval=0.33-0.74). We found no significant differences 15-28, 29-56, or 57-365 days post-release. CONCLUSION MOUD group had lower risk of non-fatal opioid overdose immediately after jail release. Wider implementation of MOUD in US jails could potentially reduce post-release overdoses, ED utilization, and associated healthcare costs.

Changes in daily dose in open-label compared to double-blind: The role of clients' expectations in injectable opioid agonist treatment. Addict Behav Rep 2023; 17:100490. [PMID: 37124402 PMCID: PMC10140796 DOI: 10.1016/j.abrep.2023.100490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 04/03/2023] [Accepted: 04/11/2023] [Indexed: 05/02/2023] Open
Abstract
Introduction Though double-blind studies have indicated that hydromorphone and diacetylmorphine produce similar effects when administered through injectable opioid agonist treatment (iOAT) programs, participant preference may influence some aspects of medication dispensation such as dose. Methods This is a retrospective longitudinal analysis. Participants (n = 131) were previously enrolled in a double-blind clinical trial for iOAT who continued to receive treatment in an open-label follow up study. Data included medication dispensation records from 2012 to 2020. Using linear regression and paired t-tests, average daily dose totals of hydromorphone and diacetylmorphine were examined comparatively between double-blind and open-label periods. A subgroup analysis explored dose difference by preference using the proxy, blinding guess, a variable used to facilitate the measurement of treatment masking during the clinical trial by asking which medication the participant thought they received. Results During the open-label period, participants prescribed diacetylmorphine received 49.5 mg less than during the double-blind period (95% CI -12.6,-86.4). Participants receiving hydromorphone did not see a significant dose decrease. Participants who guessed they received hydromorphone during the clinical trial, but learned they were on diacetylmorphine during the open-label period, saw a decrease in total daily dose of 78.3 mg less (95% CI -134.3,-22.4) during the open-label period. Conclusion If client preference is considered in the treatment of chronic opioid use disorder, clients may be able to better moderate their dose to suit their individual needs. Together with their healthcare providers, clients can participate in their treatment trajectories collaboratively to optimize client outcomes and promote person-centered treatment options.

Abstract
Background Medications for Opioid Use Disorder (MOUD) are efficacious, however only one-third of individuals with an opioid use disorder (OUD) enter into treatment. Low rates of MOUD utilization are partially due to stigma. This study examines provider-based stigma toward MOUD and identifies factors associated with experiencing stigma related to MOUD from substance use treatment and healthcare providers among people receiving methadone. Methods Clients receiving MOUD at an opioid treatment program (N = 247) were recruited to complete a cross-sectional computer-based survey assessing socio-demographics, substance use, depression and anxiety symptoms, self-stigma, and recovery supports/barriers. Logistic regression was used to examine factors associated with hearing negative comments about MOUD from substance use treatment and healthcare providers. Results 27.9% and 56.7% of respondents reported they sometimes/often hear negative comments about MOUD from substance use treatment and healthcare providers, respectively. Logistic regression results indicate that individuals who experience more negative consequences resulting from their OUD (OR=1.09, p=.019) had greater odds of hearing negative comments from substance use treatment providers. Age (OR=0.966, p=.017) and treatment stigma (OR=1.42, p=.030) were associated with greater odds of hearing negative comments from healthcare providers. Conclusions Stigma can be a deterrent to seeking substance use treatment, healthcare, and recovery support. Understanding factors associated with experiencing stigma from substance use treatment providers and healthcare providers is important as these individuals may act as advocates for those with OUD. This study highlights individual factors associated with hearing negative comments about methadone and other MOUD and point to areas for targeted education.

J Subst Abuse Treat 2023; 144:108918. [PMID: 36403456 DOI: 10.1016/j.jsat.2022.108918] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Revised: 08/17/2022] [Accepted: 10/23/2022] [Indexed: 11/18/2022]
Abstract
INTRODUCTION Clinical guidelines strongly recommend opioid agonist treatment (OAT) as first-line treatment for opioid use disorder (OUD). However, racial/ethnic minoritized patients are less likely to receive OAT compared to non-Hispanic White patients. Reasons for this treatment gap must be elucidated to address racial/ethnic disparities in OAT. Our objective is to evaluate perceptions of and barriers to OAT across racial/ethnic groups in individuals with OUD (not on OAT). METHODS This qualitative study used semi-structured telephone interviews of adult patients (n = 41) with OUD (not currently being treated with OAT) from the Boston area from September 2020 through February 2021. We developed a codebook through author consensus based on review of themes in initial transcripts. We performed qualitative thematic analysis of the transcripts. We evaluated patients' perceptions of treatment for OUD across the study population and analyzed differences and similarities in perceptions between racial and ethnic groups. RESULTS Across all racial/ethnic categories in our sample, anticipated stigma was the most frequently reported barrier to OAT and most patients preferred non-OAT methods for treatment. Non-Hispanic White participants had more favorable opinions of OAT compared to racial/ethnic minoritized participants. Racial/ethnic minoritized participants reported social support as the main facilitator to addiction treatment, while non-Hispanic White participants reported self-motivation as the most important factor. Racial/ethnic minoritized participants preferred treatment for OUD via non-OAT treatments and their second most preferred option was residential treatment. Non-Hispanic White participants preferred naltrexone and their second most preferred option was non-OAT treatments. CONCLUSIONS Racial/ethnic minoritized patients' preference for residential treatment and social support, along with their distrust of OAT, illustrates a desire for psychosocial and peer recovery-based care that addresses social determinants of health. Addiction specialists may improve engagement with and treatment of racial/ethnic minoritized groups with culturally tailored interventions for OUD that offer psychosocial treatment in combination with OAT, and by partnering with organizations with strong ties to racial/ethnic minoritized communities. This kind of response would reflect the structural and cultural humility that is needed to adequately address the OUD needs of these underserved populations.

Abstract
BACKGROUND Medication treatment for opioid use disorder (OUD) (MOUD; buprenorphine and methadone) reduces opioid use and overdose. Discontinuation of MOUD can quickly lead to relapse, overdose and death. Few persons who initiate MOUD are retained on treatment, thus it is critical to identify factors associated with retention. METHODS Evaluated data was from an ongoing prospective cohort study of adults aged 18 or older with DSM-5 moderate to severe OUD seeking MOUD in the community and followed for 6 months. Participants were considered retained on MOUD through 6 months if they reported taking MOUD at every study interview without discontinuation. A high dose of MOUD was defined as a methadone dose > 85 mg or buprenorphine dose ≥ 16 mg. Multivariable logistic regression was conducted to assess factors associated with 6-month MOUD retention. RESULTS A total of 118 participants (73% male, 58% white, 36% with HIV) were included. Buprenorphine was initiated by 58% and 42% started methadone. MOUD retention was 49% and 58% among buprenorphine and methadone, respectively, at 6-months. In adjusted models, a high MOUD dose (OR = 4.71, 95% CI 2.05-10.84) and higher pain interference (OR = 1.59, 95% CI 1.15-2.19) was associated with MOUD retention. CONCLUSIONS Adequate dosing of MOUD leads to improved retention on MOUD. Further, persons with high pain interference at baseline had higher odds of retention on MOUD. Both methadone and buprenorphine have analgesic effects, thus those with high pain interference could have dual benefits of MOUD for treating OUD and pain. Interventions should be tailored to improve adequate MOUD dosing to improve retention on MOUD.

Treatment options and shared decision-making in the treatment of opioid use disorder: A scoping review. J Subst Abuse Treat 2021; 135:108646. [PMID: 34810044 DOI: 10.1016/j.jsat.2021.108646] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 09/17/2021] [Accepted: 10/13/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Shared decision-making (SDM) is an approach to clinical decision-making that includes patients' values and preferences during health-related decisions. Previous research suggests that SDM may be beneficial in the treatment of substance use disorders; however, the impact of SDM in the treatment of opioid use disorder (OUD) remains unclear. OBJECTIVES To identify relevant peer-reviewed literature related to SDM in the treatment of adults with OUD, and to summarize the main findings according to patient outcomes. METHODS The research team conducted a scoping review. The team searched five electronic health databases from database inception until September 2019 using MeSH and keywords related to SDM. The team included only peer-reviewed studies where adults (≥18 years) with OUD were provided a choice and/or allowed input into their treatment plan. Two independent reviewers screened, extracted, and assessed the quality of included studies. RESULTS Fourteen studies (n = 1748 participants) met inclusion criteria, including seven randomized controlled trials, three non-randomized controlled trials, two observational studies, and one qualitative study. Treatment options included: patient regulated methadone dosing vs. fixed dosing (n = 4 studies), optional vs. mandatory counseling (n = 4 studies), home vs. office buprenorphine inductions (n = 2 studies), and inpatient vs. outpatient treatment (n = 1 study). None of the studies measured SDM with a validated instrument. Seven of 14 studies reported at least one improved patient outcome. CONCLUSIONS The review found few studies that explored whether providing treatment options and/or encouraging participation in decision-making are beneficial for adults with OUD. Preliminary evidence suggests that SDM may be promising for this population. However, the field needs more research on person-centered care and SDM.

Abstract
OBJECTIVE To summarize the available conceptual models for factors contributing to medication adherence based on the World Health Organization (WHO)'s five dimensions of medication adherence via a systematic review, identify the patient groups described in available conceptual models, and present an adaptable conceptual model that describes the factors contributing to medication adherence in the identified patient groups. METHODS We searched PubMed®, Embase®, CINAHL®, and PsycINFO® for English language articles published from inception until 31 March 2020. Full-text original publications in English that presented theoretical or conceptual models for factors contributing to medication adherence were included. Studies that presented statistical models were excluded. Two authors independently extracted the data. RESULTS We identified 102 conceptual models, and classified the factors contributing to medication adherence using the WHO's five dimensions of medication adherence, namely patient-related, medication-related, condition-related, healthcare system/healthcare provider-related, and socioeconomic factors. Eight patient groups were identified based on age and disease condition. The most universally addressed factors were patient-related factors. Medication-related, condition-related, healthcare system-related, and socioeconomic factors were represented to various extents depending on the patient group. By systematically examining how the WHO's five dimensions of medication adherence were applied differently across the eight different patient groups, we present a conceptual model that can be adapted to summarize the common factors contributing to medication adherence in different patient groups. CONCLUSION Our conceptual models can be utilized as a guide for clinicians and researchers in identifying the facilitators and barriers to medication adherence and developing future interventions to improve medication adherence.

Abstract
Medications for opioid use disorder (MOUD) are evidence-based treatments, yet can be controversial among some populations. This study provides a systematic review of prejudice and discrimination toward MOUD, a form of "intervention stigma," or stigma associated with a particular medical treatment. A systematic search strategy was used in PsychInfo and PubMed to identify studies published between 1998 and 2018. Studies that empirically examined stigma toward MOUD were included if the manuscript was of moderate or high quality. Studies were analyzed using thematic synthesis. The search yielded 972 studies, of which 28 were included. Most studies utilized qualitative methods to examine intervention stigma toward methadone or buprenorphine, with one including naltrexone. Studies demonstrated that intervention stigma among healthcare providers was influenced by lack of training and abstinent treatment preferences. Providers equated MOUD with illicit substance use and at times refused to care for MOUD patients. Stigma among peer patients seeking treatment was also influenced by abstinent treatment preferences, and among the general public stigma was influenced by lack of MOUD knowledge. Intervention stigma was also driven at the policy level by high regulation of methadone, which fueled diversion and hindered social functioning among patients. Few studies indicated how to reduce intervention stigma toward MOUD. Intervention stigma affects both provision and perceptions of methadone and buprenorphine, decreasing access and utilization of MOUD. Future research should further develop and test MOUD stigma reduction interventions in a variety of social contexts to improve access to care and reduce patient barriers.

J Subst Abuse Treat 2020; 119:108146. [PMID: 33138929 PMCID: PMC7609980 DOI: 10.1016/j.jsat.2020.108146] [Citation(s) in RCA: 81] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 07/02/2020] [Accepted: 09/10/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND The opioid epidemic is a public health crisis. Medications for opioid use disorder (MOUD) include: 1) buprenorphine, 2) methadone, and 3) extended-release naltrexone (XR-NTX). Research should investigate patients' and providers' perspectives of MOUD since they can influence prescription, retention, and recovery. METHODS This systematic review focused on patients' and providers' perceptions of MOUD. The review eligibility criteria included inclusion of the outcome of interest, in English, and involving persons ≥18 years. A PubMed database search yielded 1692 results; we included 152 articles in the final review. RESULTS There were 63 articles about buprenorphine, 115 articles about methadone, and 16 about naltrexone. Misinformation and stigma associated with MOUD were common patient themes. Providers reported lack of training and resources as barriers to MOUD. CONCLUSION This review suggests that patients have significant misinformation regarding MOUD. Due to the severity of the opioid epidemic, research must consider the effects of patients' and providers' perspectives on treatment for OUD, including the effects on the type of MOUD prescribed, patient retention and adherence, and ultimately the number of patients treated for OUD, which will aid in curbing the opioid epidemic.

Abstract
BACKGROUND Opioid agonist treatment is considered important in preventing acquisition of hepatitis C virus (HCV) among people who inject drugs; however, the role of dosage in opioid agonist treatment is unclear. We investigated the joint association of prescribed dosage of opioid agonist treatment and patient-perceived dosage adequacy with risk of HCV infection among people who inject drugs. METHODS We followed prospectively people who inject drugs at risk of acquiring HCV infection (who were RNA negative and HCV-antibody negative or positive) in Montréal, Canada (2004-2017). At 6-month, then 3-month intervals, participants were tested for HCV antibodies or RNA, and completed an interviewer-administered behavioural questionnaire, reporting the following: current exposure to opioid agonist treatment (yes/no), prescribed dosage either high (methadone ≥ 60 mg/d or buprenorphine ≥ 16 mg/d) or low, and perceived dosage adequacy (adequate/inadequate). We then assigned participants to 1 of 5 exposure categories: no opioid agonist treatment, high dosage of opioid agonist treatment perceived to be adequate, high dosage perceived to be inadequate, low dosage perceived to be adequate or low dosage perceived to be inadequate. To estimate associations between categories of opioid agonist treatment dosage and incident HCV infection, we conducted Cox regression analyses, adjusting for multiple confounding factors. RESULTS Of 513 participants (median age 35.0 yr, 77.6% male), 168 acquired HCV over 1422.6 person-years of follow-up (incidence 11.8/100 person-years, 95% confidence interval [CI] 10.1-13.7). We observed a gradient in the relative risks of HCV infection across categories of opioid agonist treatment dosage. Compared with people who inject drugs not receiving opioid agonist treatment, adjusted hazard ratios were 0.43 (95% CI 0.23-0.84) for those receiving high dosages perceived to be adequate, 0.61 (95% CI 0.25-1.50) for those receiving high dosages perceived to be inadequate, 1.22 (95% CI 0.74-2.00) for those receiving low dosages perceived to be adequate and 1.94 (95% CI 1.11-3.39) for those receiving low dosages perceived to be inadequate. INTERPRETATION Risk of HCV infection varies considerably according to dosage of opioid agonist treatment and patient-perceived adequacy, with associations indicating both protective and harmful effects relative to no exposure to opioid agonist treatment.

Abstract
INTRODUCTION Integration of HIV- and opioid use disorder (OUD)-related care is associated with improved patient outcomes. Our goal was to develop a novel instrument for measuring quality of integration of HIV and OUD-related care that would be applicable across diverse care settings. METHODS Grounded in community-based participatory research principles, we conducted a qualitative study from August through November 2017 to inform modification of the Behavioral Health Integration in Medical Care (BHIMC) instrument, a validated measure of quality of integration of behavioral health in primary care. We conducted semi-structured interviews of patients (n = 22), focus groups with clinical staff (n = 24), and semi-structured interviews of clinic leadership (n = 5) in two urban centers in Connecticut. RESULTS We identified three themes that characterize optimal integration of HIV- and OUD-related care: (1) importance of mitigating mismatches in resources and knowledge, particularly resources to address social risks and knowledge gaps about evidence-based treatments for OUD; (2) need for patient-centered policies and inter-organization communication, and (3) importance of meeting people where they are, geographically and at their stage of change. These themes highlighted aspects of integrated care for HIV and OUD not captured in the original BHIMC. CONCLUSIONS Patients, clinical staff, and organization leadership perceive that addressing social risks, communication across agencies, and meeting patients in their psychosocial and structural context are important for optimizing integration of HIV and OUD-related care. Our proposed, novel instrument is a step towards measuring and improving service delivery locally and nationally for this vulnerable population.

Abstract
Substance use disorders (SUDs) take a heavy toll on those who have them and on society more broadly. These disorders are often difficult to treat, and relapse is common. Perhaps, because of these factors, these disorders are highly stigmatized worldwide. The purpose of this study is to examine empirical work intended to determine the impact of perceived social stigma and self-stigma on the process of recovering from SUDs with the assistance of formal treatment services. Qualitative studies confirmed that stigma experiences are common among those with these disorders and that these experiences can negatively impact feelings and beliefs about treatment. One quantitative study provided good statistical support for a direct effect of stigma on outcomes, but this was contradicted by other longitudinal data. In general, quantitative articles suggested an indirect effect of stigma on treatment outcomes, via negative emotions and cognitive mechanisms such as feelings of self-efficacy. However, it was notable that there was little consistency in the literature as to definitions and measurement of the constructs of recovery, perceived social stigma, and self-stigma. Future work should focus on bringing clarity, and validated measures, to this problem in order to better determine the nature of these relationships.

Abstract
BACKGROUND Buprenorphine dosage is a crucial factor influencing outcomes of buprenorphine treatment for heroin use disorders. Therefore, the aim of the present study is to identify naturally occurring profiles of heroin-dependent patients regarding individualized management of buprenorphine dosage in clinical practice of buprenorphine-naloxone maintenance treatment. METHODS 316 patients receiving buprenorphine-naloxone maintenance treatment were surveyed at 16 Spanish centers during the stabilization phase of this treatment. Patients were grouped using cluster analysis based on three key indicators of buprenorphine dosage management: dose, adequacy according to physician, and adjustment according to patient. The clusters obtained were compared regarding different facets of patient clinical condition. RESULTS Four clusters were identified and labeled as follows (buprenorphine average dose and percentage of participants in each cluster are given in brackets): "Clinically Adequate and Adjusted to Patient Desired Low Dosage" (2.60 mg/d, 37.05%); "Clinically Adequate and Adjusted to Patient Desired High Dosage" (10.71 mg/d, 29.18%); "Clinically Adequate and Patient Desired Reduction of Low Dosage" (3.38 mg/d, 20.0%); and "Clinically Inadequate and Adjusted to Patient Desired Moderate Dosage" (7.55 mg/d, 13.77%). Compared to patients from the other three clusters, participants in the latter cluster reported more frequent use of heroin and cocaine during last week, lower satisfaction with buprenorphine-naloxone as a medication, higher prevalence of buprenorphine-naloxone adverse effects and poorer psychological adjustment. CONCLUSIONS Our results show notable differences between clusters of heroin-dependent patients regarding buprenorphine dosage management. We also identified a group of patients receiving clinically inadequate buprenorphine dosage, which was related to poorer clinical condition.

Evidence of validity and reliability of the Opiate Dosage Adequacy Scale (ODAS) in a sample of heroin addicted patients in buprenorphine/naloxone maintenance treatment. Drug Alcohol Depend 2018; 183:127-133. [PMID: 29247974 DOI: 10.1016/j.drugalcdep.2017.10.035] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2017] [Revised: 10/21/2017] [Accepted: 10/24/2017] [Indexed: 10/18/2022]
Abstract
OBJECTIVE The Opiate Dosage Adequacy Scale (ODAS) is a clinical tool to individually measure the "adequacy" of opioid doses in patients on maintenance treatment. The aim of this paper is to provide evidence for the validity and reliability of the ODAS in a sample of patients in buprenorphine/naloxone (B/N) maintenance treatment. METHOD Cross-sectional study of a convenience sample of B/N-treated patients (n = 316) from four Autonomous Communities in Spain. Participants completed a battery of instruments to assess the following: buprenorphine dose adequacy; heroin dependence severity; psychological adjustment; and patient-desired adjustment of buprenorphine dose. RESULTS Exploratory Factor Analysis identified four factors from the ODAS that together account for 85.4% of the total variance: "Heroin craving and use"; "Overmedication"; "Objective opiate withdrawal symptoms (OWS)" and 'Subjective OWS'. Compared to patients with an "inadequate" B/N dose (ODAS), patients with "adequate" doses had less heroin use in the last week (0.01 vs. 0.40; t = -2.73; p < 0.01, 95% CI: -0.67, -0.10), less severe heroin dependence (2.20 vs. 5.26, t = -5.14, p < 0.001; 95% CI: -4.23, -1.88), less psychological distress (3.00 vs. 6.31, t = -4.37, p < 0.001; 95% CI: -4.80, -1.81), and greater satisfaction with their doses (42.1% vs. 13.6%, χ2 = 14.44, p < 0.01). Cronbach's alpha coefficient was 0.76 (0.81, 0.92, 0.94, and 0.93, respectively, for the four factor dimensions). CONCLUSION These findings support the validity and reliability of the ODAS as a tool to measure and assess buprenorphine dose adequacy in the context of an opioid dependency treatment program.

Patient perception of methadone dose adequacy in methadone maintenance treatment: The role of perceived participation in dosage decisions. PATIENT EDUCATION AND COUNSELING 2017; 100:981-986.

Abstract
OBJECTIVE In clinical practice, methadone maintenance treatment (MMT) entails tailoring the methadone dose to the patient's specific needs, thereby individualizing treatment. The aim of this study was to identify the independent factors that may significantly explain methadone dose adequacy from the patient's perspective. METHOD Secondary analysis of data collected in a treatment satisfaction survey carried out among a representative sample of MMT patients (n=122) from the region of La Rioja (Spain). As part of the original study protocol, participants completed a comprehensive battery to assess satisfaction with MMT, psychological distress, opinion of methadone as a medication, participation in dosage decisions, and perception of dose adequacy. RESULTS Multivariate binary logistic regression showed that the only variable independently associated with the likelihood of a patient perceiving methadone dose as inadequate was the variable perceived-participation in methadone dosage decisions (OR=0.538, 95% CI=0.349-0.828). CONCLUSION Patient participation in methadone dosage decisions was predictive of perceived adequacy of methadone dose beyond the contribution of other socio-demographic, clinical, and MMT variables. PRACTICE IMPLICATIONS Patient participation in methadone dosage decision-making is valuable for developing a genuinely patient-centred MMT.

Abstract
SETTING Thirteen methadone maintenance treatment (MMT) clinics across Yunnan, the province with the highest human immunodeficiency virus (HIV) burden in China. OBJECTIVES To determine, among HIV-negative participants on MMT, the proportion lost to follow-up (defined as those who missed the 6-monthly follow-up examination), factors associated with loss to follow-up (LFU), HIV seroconversion rate and factors associated with seroconversion. DESIGN Prospective cohort study from October 2008 to April 2011. All participants were administered a pre-tested structured questionnaire to capture associated factors and offered HIV testing every 6 months. χ(2) test and log-binomial regression were used for data analysis. RESULTS Of 1146 participants, 541 (47%) were lost to follow-up in 2.5 years. Factors associated with higher LFU proportion include <6 months of previous MMT, inconvenient location of the MMT clinic and average methadone dose ⩽60 mg/day, with adjusted relative risks (RRs) of respectively 1.4 (95%CI 1.2-1.5), 1.2 (95%CI 1.0-1.4) and 1.1 (95%CI 1.0-1.3). The overall HIV seroconversion rate was 6.6 (95%CI 3.7-11.0) per 1000 person-years. Not living with a partner contributed to higher HIV rates, with an adjusted RR of 3.6 (95%CI 1.0-12.8). CONCLUSION The retention rate of MMT participants in Yunnan was not satisfactory. Decentralising service delivery in the community and making directly observed treatment more convenient has the potential to improve retention.

Abstract
OBJECTIVES To identify factors associated with Opioid Agonist Treatment (OAT) satisfaction and to determine whether these relationships are gender specific. METHODS This study was based on data collected in a cross-sectional study among long-term opioid-dependent individuals (n = 160; 46.3% women). Participants completed the Client Satisfaction Questionnaire in reference to OAT episodes. Sociodemographic, illicit substance use, health, and addiction treatment history data were collected. Multivariable linear regression was used to determine the relationship between these variables and treatment satisfaction. To explore the potential role of gender in these identified relationships stratified multivariable models were tested. Additional open-ended questions regarding positive and negative perceptions of treatment were collected, and a thematic analysis was conducted. RESULTS In the multivariable linear regression model, participants who were older, of Aboriginal ancestry, and currently receiving OAT had higher OAT satisfaction scores, whereas participants who had methadone dose preferences of 30 mg or less had lower OAT satisfaction. In stratified analyses among women, the relationship between preferred methadone dose and current OAT remained significantly associated with satisfaction. Open-ended positive and negative perceptions complemented and provided further valuable data to interpret these identified relationships. CONCLUSIONS To our knowledge, this is the first study to explore the potential role of gender in factors associated with OAT satisfaction. These findings provide valuable information to health care providers working in OAT settings regarding how to address women and men's OAT needs and improve treatment satisfaction.

Dose-response relationship between methadone dose and adherence to antiretroviral therapy among HIV-positive people who use illicit opioids. Addiction 2015; 110:1330-9. [PMID: 25940906 PMCID: PMC4503496 DOI: 10.1111/add.12970] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2014] [Revised: 03/12/2015] [Accepted: 04/27/2015] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND AIMS For HIV-positive individuals who use illicit opioids, engagement in methadone maintenance therapy (MMT) can contribute to improved HIV treatment outcomes. However, to our knowledge, the role of methadone dosing in adherence to antiretroviral therapy (ART) has not yet been investigated. We sought to examine the relationship between methadone dose and ART adherence among a cohort of people who use illicit opioids. DESIGN AND SETTING We used data from the AIDS Care Cohort to Evaluate Access to Survival Services (ACCESS) study, an ongoing prospective observational cohort of HIV-positive people who use illicit drugs in Vancouver, Canada, linked confidentially to comprehensive HIV treatment data in a setting of universal no-cost medical care, including medications. We evaluated the longitudinal relationship between methadone dose and the likelihood of ≥ 95% adherence to ART among ART-exposed participants during periods of engagement in MMT. PARTICIPANTS Two hundred and ninety-seven ART-exposed individuals on MMT were recruited between December 2005 and May 2013 and followed for a median of 42.1 months. MEASUREMENTS We measured methadone dose at ≥ 100 versus < 100 mg/day and the likelihood of ≥ 95% adherence to ART. FINDINGS In adjusted generalized estimating equation (GEE) analyses, MMT dose ≥ 100 mg/day was associated independently with optimal adherence to ART [adjusted odds ratio (AOR) = 1.38; 95% confidence interval (CI) = 1.08-1.77). In a subanalysis, we observed a dose-response relationship between increasing MMT dose and ART adherence (AOR = 1.06 per 20 mg/day increase, 95% CI = 1.00-1.12). CONCLUSION Among HIV-positive individuals in methadone maintenance therapy, those receiving higher doses of methadone (≥ 100 mg/day) are more likely to achieve ≥ 95% adherence to antiretroviral therapy than those receiving lower doses.
