Heroin Dependence, Mortality, Quality of Life, Sleep Impairment, Treatment Outcome

Methadone maintenance treatment (MMT) has been one of the most effective treatment choices for opioid addicts to reduce their heroin use, criminality and spread of HIV. In Taiwan, MMT has been introduced since 2006. To date, more than 30,000 opioid addicts have ever participated in MMT, but only around 10,000 retains in treatment. Outcomes of the ever-treated MMT patients remain unclear. It is crucial to trace the opioid addicts' treatment career, outcomes and unmet treatment needs for the service providers to modify treatment strategy to help these individual to maintain abstinence. Moreover, understanding of the determinants for these subjects' long-term outcomes is important for policy makers to implement realistic policies to motivate the service providers and patients. From the results of previous research, the research team found that early dropout, defined as stayed in-treatment less than one month, of MMT participants were 14.4%. The rate of maintaining in treatment at 3rd , 6th, and 12th month were 65.7%、51.3% and 33.8%, respectively. Average treatment days for 12-month is 186.9±141.2. This result showed that the effectiveness of the MMT was varied among different facilities. On the other hand, the quality of the MMT can be improved largely through different dimensions. Besides, if one participant can enhance its motivation in staying in-treatment, it could reduce 15% early dropout. Above all, the result also showed that though the quality of life was recorded as improved after MMT, it appeared to be significantly lower than their healthy counterparties. The assessments of health outcomes after participating MMT are rare, but in need. It is necessary to make some modification to improve the effectiveness. Moreover, the evaluation of the needs shall not limit to patients, but also extend to their family members. Therefore, in this study, the research team plans to probe the dimensions from physical, psychiatric, to social conditions by assessing patients and their family members after treated by MMT for five years. The research team would like to know more about the outcomes of those who attended MMT five years ago, their physical and mental health conditions, also health status of their family members.
