This study examined the methadone maintenance therapy (MMT) retention rates of heroin users in Taiwan and the predictors for dropout in the 18-month period after starting MMT. We consecutively recruited 368 intravenous heroin users receiving MMT in 2007-2008 and applied Cox proportional hazards regression analysis to determine the predictive effect of pre- and in-treatment variables on early discontinuation of MMT. The retention rate at 18 months was 32.3%. High heroin expenses, more severe harm caused by heroin use, perceived lower family support, and lower methadone dosage at 3 months after starting MMT increased the risk of dropout in the follow-up period.

    ABSTRACT: Completion of addiction treatment is one of the most consistent factors associated with a favorable treatment outcome. Unfortunately, it is more common for a patient to drop-out of addiction treatment than to complete the treatment. To prevent drop-out, risk factors must be identified. This box-score review focuses on studies investigating the risk factors associated with drop-out from addiction treatment published in peer-reviewed journals from 1992 to 2013. A total of 122 studies involving 199,331 participants met the inclusion criteria. Contrary to recommendations from previous reviews, 91% of the included studies focused primarily on enduring patient factors, mainly demographics. The most consistent risk factors across the different study designs, samples, and measurement methods were cognitive deficits, low treatment alliance, personality disorder, and younger age. With the exception of younger age, none of the demographic factors emerged as consistent risk factors. Further research on the relationship between simple demographic factors and drop-out risk is of limited value. However, little is known about the potential risk factors related to treatment programs and to the treatment processes. Based on the review, clinical recommendations include assessing cognitive functioning and personality disorders at baseline and continuous monitoring of treatment alliance.

    ABSTRACT: While methadone maintenance treatment (MMT) is beneficial for heroin dependence, there is little information regarding the reductions in monetary cost and gains in productivity following MMT. The aim of this study was to evaluate the changes in the monetary cost of heroin addiction and productivity after one year of MMT. Twenty-nine participants from an MMT clinic were included. The monetary cost, productivity, quality of life (QOL) and mental health status were assessed at both baseline and one year follow-up. The average annual total cost was approximately US$26,485 (1.43 GDP per capita in 2010) at baseline, and decreased by 59.3% to US$10,784 (0.58 GDP) at follow-up. The mean number of months of unemployment dropped from 6.03 to 2.79, the mean income increased to exceed the basic salary, but only reached 45.3% of the national average monthly earnings. The participants׳ mental health improved, but their QOL scores did not increase significantly. After one year of MMT, the monetary cost of heroin addiction fell, both the productivity and mental health of the participants׳ improved, but limited gains were seen with regard to their QOL.

    ABSTRACT: Целью работы является исследование изменений в отношениях пациентов заместительной терапии метадоном с близкими им людьми. Исследование проводилось на базе УЗ «Городской клинический наркологический диспансер» г. Минска. Проведен опрос 47 человек, являющихся близкими людьми пациентов заместительной терапии метадоном. Результаты анонимного анкетного опроса показали улучшение отношений с пациентов с близкими людьми. Улучшились удовлетворенность респондентов своим материальным достатком, состоянием здоровья и внешностью пациентов. В исследовании показано позитивное изменение отношения близких пациентам людей к заместительной терапии метадоном как к способу лечения зависимости. The main purpose of this work is to study changes that were observed in relations with family members of the methadone maintenance treatment patients. The study was based on the data received from City Clinical Drug Dispensary of Minsk. There were questioned 47 relatives of methadone maintenance treatment patients. The anonymous survey showed that the relations between patients and their families became better. The respondents were better satisfied with their material prosperity and the patients’ health and appearance. In the study it was also marked that the relatives’ attitude to methadone maintenance treatment as a way an addiction cure was changed from negative to positive.
