Methadone treatment in clinical practice in Italy: need for improvement.
BACKGROUND
Methadone at appropriate doses has been demonstrated to be the most effective means for retaining patients in treatment and suppressing heroin use.


OBJECTIVE
To describe the modalities of day-to-day provision of methadone maintenance treatments (MMT) in Italian public health centres and to analyze the duration of MMTs by dose and by association with psychosocial treatments.


METHODS
We analyzed 8,378 subjects, 18 years of age or over, enrolled between September 1998 and March 2001 in one of 115 public treatment centres for heroin dependence in Italy. Treatment data were collected for each subject from enrolment to the end of the study period (maximum of 18 months).


RESULTS
Of the total of 29,495 treatments delivered, 21.0% were methadone maintenance, and 34.4% were methadone detoxification. Fifty percent of MMTs offered had a mean dose less than or equal to 40 mg/day, and only 19% had doses higher than or equal to 60 mg/day; treatments with doses higher than 60 mg/day lasted longer than treatments with lower doses. Differences in treatment length were observed between MMTs associated with a psychosocial treatment and those offered alone, only for doses <60 mg/day.


CONCLUSIONS
In Italy, MMTs are delivered at inappropriate doses in more than 80% of the cases. The increase of methadone doses to adequate levels as indicated by the literature is necessary to ensure proper and effective use of MMTs in public treatment centres for heroin users.
