[PMID: 32289189 PMCID: PMC7554123 DOI: 10.1111/add.15087] [Citation(s) in RCA: 46] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 11/28/2019] [Accepted: 04/03/2020] [Indexed: 01/30/2023]
Abstract
AIMS We assessed how opioid agonist treatment (OAT) for opioid use disorder (OUD), specifically methadone and buprenorphine, including buprenorphine-naloxone, is delivered in routine clinical practice, with a focus on factors that affect access to and delivery of these services. The aims of this review were to summarize eligibility criteria for entry to OAT, doses in routine clinical practice, access to and eligibility for unsupervised dosing and urine drug screening practices in OAT programs globally. METHODS We completed searches of PubMed, Embase, and grey literature databases for cross-sectional or observational cohort studies of OAT using either methadone or buprenorphine. Dose data extracted from eligible studies were compared with guidelines provided by WHO. RESULTS We found 140 reports from 41 countries that contained data for at least one of the relevant indicators. A diagnosis of opioid dependence or opioid use disorder was the most common eligibility requirement for OAT (13 or 17 countries). Reported mean or median doses for methadone ranged from 16-131 mg whereas range for buprenorphine was 2.5-19 mg. Access to unsupervised dosing under some conditions was reported in 18 of 27 countries. Frequency of regular urine drug screenings (UDS) ranged from several times a week to eight times per year (methadone) or as clinically indicated. CONCLUSIONS Opioid agonist treatment practices, including doses prescribed, vary greatly both within and across countries. Of particular concern is the persistence of lower dose prescribing practices, in which patients may be prescribed doses below those proven to yield significant clinical benefits.

Effectiveness of a Psycho-Social Intervention Aimed at Reducing Attrition at Methadone Maintenance Treatment Clinics: A Propensity Score Matching Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E4337. [PMID: 31703302 PMCID: PMC6888175 DOI: 10.3390/ijerph16224337] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/19/2019] [Revised: 10/30/2019] [Accepted: 11/04/2019] [Indexed: 12/16/2022]
Abstract
Methadone maintenance treatment (MMT) is an important approach to address opioid dependence. However, MMT clinics usually report high attrition rates. Our previous randomized controlled trial demonstrated additional psycho-social services delivered by social workers could reduce attrition rates compared to MMT alone. This study aimed to evaluate the effectiveness of psycho-social service in a real-world context. A quasi-experimental design and propensity score matching was adopted. 359 clients were recruited from five MMT clinics in Guangzhou from July 2013 to April 2015. One 20-minute counseling session was offered to the control group after enrolment. The intervention group received six sessions of psycho-social services. The baseline characteristics were unbalanced between two arms in the original sample. After propensity score matching, 248 participants remained in the analysis. At month six, the intervention group had a lower attrition rate [intervention (39.5%) versus control (52.4%), P = 0.041], higher monthly income [monthly income of 1000 CNY or higher: intervention (55.9%) versus control (39.0%), P = 0.028)], higher detoxification intention score [full intention score: intervention (51.6%) versus control (32.5%), P = 0.012)], higher family support in MMT participation [intervention (77.9%) versus control (61.4%), P = 0.049)]. This study demonstrated that psycho-social services delivered by social workers can reduce MMT clients' attrition and improve their well-being in real-world settings.

Similarities and changes between 15- and 24-year survival and retention rates of patients in a large medical-affiliated methadone maintenance treatment (MMT) center. Drug Alcohol Depend 2018; 185:112-119. [PMID: 29432974 DOI: 10.1016/j.drugalcdep.2017.11.034] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Revised: 11/26/2017] [Accepted: 11/28/2017] [Indexed: 12/30/2022]
Abstract
BACKGROUND Environmental and social trends and patients' characteristics may affect predictors for methadone maintenance treatment (MMT) outcome. METHODS We have expanded our previous study of predictors for MMT outcome (from 619 to 890 patients) and the study period (from 15 to 24 years). Survival and retention in MMT since admission to the MMT clinic (6/1993-6/2016) and until death or study closure (6/2017) were compiled and analyzed. RESULTS Of 890 patients ever admitted (10,146.9 person-years (py)), 237 passed away (116 while in MMT). The mortality rate did not differ between those who stayed or left (2.6 vs. 2.1 per 100 py, p = 0.1), but it was lower among those who stayed ≥1 year during any admission (2.1 vs. 3.3 per 100 py, respectively, p = 0.004). Age <40 years, no hepatitis C or B, no HIV, and no benzodiazepine abuse after one year predicted longer survival (multivariate analyses). No opiate or benzodiazepine abuse after one year, methadone dose ≥100 mg/d, no DSM-IV-TR Axis II diagnosis only, and no direct hospital referral predicted longer retention. Cocaine abuse predicted poor retention and survival among 271 patients admitted during the extended part of the study period. CONCLUSIONS Predictors for retention (associated with MMT outcome) and mortality (associated with pre-treatment comorbidity) after 24 years were similar to those after 15 years. Cocaine abuse as a predictor of both poor retention and poor survival in the later period may reflect the escalating trend for cocaine abuse and should be studied if related to other unmonitored substances.

Abstract
Background The rapid expansion of methadone maintenance treatment (MMT) services has significantly improved health status and quality of life of patients. However, little is known about its impacts on addiction-related stigma and associated factors. Methods A cross-sectional survey was conducted in 2013 in Vietnam’s capital, Hanoi, and Nam Dinh province among 1016 methadone maintenance patients; 26.6 % at provincial AIDS centers (PAC) and 73.4 % at district health centers (DHC), respectively. Drug addiction history and related stigma, health status, MMT-related covariates, and sociodemographic characteristics were interviewed. Results More than one-sixth of the sample reported experiencing felt or enacted stigma, including Blame or Judgement (17.2 %), Shame (19.9 %), or Others’ fear of HIV transmission (17.1 %). These proportions were higher in PACs than in DHCs, which are integrated with other HIV or general health care services. Very few patients reported being discriminated at the workplace (2.5 %) or at health care services (1.7 %); however, 15.6 % of patients at PACs and 10.6 % of patients at DHCs reported discrimination in their communities. Drug users taking MMT for longer periods were less likely to report felt stigma. Other factors associated with stigma against MMT patients included the lack of comprehensive services, higher education, presence of pain/discomfort, and anxiety/depression, self-reported HIV positive, and number of previous drug rehabilitation episodes. Conclusion The study shows a high level of stigma against MMT patients and emphasizes the necessity to integrate MMT with comprehensive health and support services. Mass communication campaigns to reduce stigma against people with drug addiction and HIV/AIDS, as well as vocational trainings and jobs referrals for MMT patients, are needed to maximize the benefits of MMT programs in Vietnam.

Abstract
BACKGROUND Integrating HIV/AIDS and methadone maintenance treatment (MMT) services with existing health care delivery system is critical in sustaining efforts to fight HIV/AIDS in large injection-driven epidemics. However, efficiency of different integrative service models is unknown. This study assessed behavioral and health-related quality-of-life (HRQOL) outcomes of MMT in four service delivery models and explored factors associated with these outcomes of interest. METHODS A cross-sectional survey was conducted in two HIV epicenters in Vietnam: Hanoi and Nam Dinh Province. All patients in five selected MMT clinics were invited to participate, and 1016 were interviewed (80-90% response rate). RESULTS Respondents had a mean age of 35.8, taken MMT for average 16.5 months and 3.3% on MMT for 36-60 months. The MMT integrated with rural district health center (DHC) has the highest prevalence of concurrent drug use (11.3%). The percentage of condom use (last sexual intercourse) with primary and casual partners was lowest in the MMT at urban DHCs. Patients at the rural DHC reported very high proportions of pain/discomfort (37.8%), anxiety/depression (43.1%), and mobility (13.3%). In regression models, poorer HRQOL outcomes were found in MMT models in the rural areas or without general health care, and among those patients who were HIV positive, reported concurrent drug use, and had higher numbers of previous drug rehabilitation episodes. Mobility and anxiety/depression are factors that increased the likelihood of concurrent drug use among MMT patients. CONCLUSIONS Outcomes of MMT were diverse across different integrative service models. Policies on rapid expansion of the MMT program in Vietnam should also emphasize on the integration with comprehensive health care services including psychological supports for patients.
