Plain English Summary
Background and study aims
People who are addicted to opiates such as heroin can be prescribed a heroin substitute such as methadone or buprenorphine to help them stop their drug use. The rapid increase in the use of opioid substitution treatment for drug users, mainly achieved through prescribing buprenorphine in primary care, has been successful in reducing HIV prevalence among drug users but is still inadequate for reducing the spread of hepatitis C. In France methadone treatment can currently only be started in drug centres but GPs can prescribe methadone after stabilisation of dosages. The main aim of this study is to compare patients who start methadone treatment in primary care and patients who start methadone treatment in Specialized Drug Addiction Treatment Centers, in order to find out whether the proportion of patients not using opioids after 1 year of treatment is the same. The other aims include assessing adherence to treatment, addictive behaviours, quality of life, psychiatric conditions, reduction in criminal acts, and cost effectiveness.
Who can participate?
Patients aged between 18 and 70 who need methadone treatment for their opioid dependence, and who have either never received methadone, have not had any methadone for at least 1 month, or need to switch from buprenorphine to methadone
What does the study involve?
Participants are randomly allocated to start taking methadone either in primary care or a specialised centre for opioid dependence. After stabilisation of dosages the participants can choose whether to change groups. The study lasts for 12 months with examinations and interviews at the start of the study and after 3, 6 and 12 months. The prevalence of daily opioid use after one year of treatment is compared between groups. The prevalence of other addictive behaviors, adherence to treatment, improvement in quality of life, psychiatric conditions, reduction in criminal acts and cost-effectiveness are also assessed.

Scientific title
Induction of methadone in primary care (ANRS-METHAVILLE): a phase III randomized non-inferiority trial in France
Acronym
Study hypothesis
The main hypothesis is that the delivery model used for first prescription (primo-prescription) of methadone does not influence injection relapses nor treatment´s effectiveness. More specifically, we hypothesize a non-inferiority after one year treatment in patients who were inducted in primary compared to those who initiated methadone in specialized centers in terms of prevalence of daily opioid users.

Primary outcome measure
1. Daily opioid use
2. Method of measurement: Opiate Treatment Index (OTI) - a multi-dimensional questionnaire based in patients self-report (REF OTI- Darke et al, 1992) 12 months after enrolment (visit M12)
3. Prevalence (%) of opioid users at M12
Secondary outcome measures
1. The prevalence of other hepatitis C virus (HCV) risk transmission practices is being documented using a series of questions extracted from a standardized questionnaire specific for this purpose, the BBV-TRAQ (Fry and Lintzeris, 2003; Tucker et al, 2004) at M12
2. Other indicators relevant for the purpose of this thesis are being collected:
2.1. Depressive symptoms Becks H questionnaire (Beck et al, 1985)
2.2. Alcohol consumption with the AUDIT questionnaire (Saunders et al, 1993)
2.3. Patient-health care provider relationship (Smith et al, 2006)
2.4. Adherence to methadone
2.5. Urinary drug screening and socio-demographic information on history of incarceration and contact with associations
