Study information

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 measures

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 Beck’s 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
