DETERMINANTS OF METHADONE TREATMENT ASSIGNMENT AMONG HEROIN ADDICT ON FIRST ADMISSION TO PUBLIC TREATMENT CENTRES IN ITALY.

Abstract

Aims: To identify factors associated with entering any methadone treatment at first admission at an NHS treatment centre in Italy and to investigate determinants of receiving detoxification or maintenance methadone treatments. Methods: Data were analysed from 565 heroin addicts who entered for the first time one of 90 NHS treatment centres in 12 Italian regions between September 1998 and March 2001. Subjects were interviewed at admission by the centre's staff and followed-up for 18 months. Details on treatments provided were recorded using a standardised form. Random effects logistic regression analysis was applied. Results: Factors positively associated with any methadone treatment assignment were: being younger than 25 years and using heroin more than twice a day, having been recently incarcerated, and living with a partner. Independent predictors of admission to methadone maintenance were injecting heroin, having sex without a condom in the previous six months, being HIV positive and having been enrolled at a NHS TC where a psychiatrist was present. Using heroin once a day or more and using cocaine were factors associated with enrolment into detoxification treatment. A significant heterogeneity between centres was observed. Conclusions: Results from this study give an insight into different patient profiles who are enrolled in methadone treatments. The observed heterogeneity between centres indicates the need to develop and implement common guidelines for the access of heroin addicts to substitution treatment. © 2005 Elsevier Ireland Ltd.
