Objective: To evaluate an experimental heroin
maintenance programme.
Design: Randomised trial.
Setting: Outpatient clinic in Geneva, Switzerland.
Subjects: Heroin addicts recruited from the community
who were socially marginalised and in poor health and had failed in at
least two previous drug treatments.
Intervention: Patients in the experimental programme
(n=27) received intravenous heroin and other health and psychosocial services. Control patients (n=24) received any other conventional drug
treatment (usually methadone maintenance).
Main outcome measures: Self reported drug use, health
status (SF-36), and social functioning.
Results: 25 experimental patients completed 6 months
in the programme, receiving a median of 480 mg of heroin daily. One
experimental subject and 10 control subjects still used street heroin
daily at follow up (difference 44%; 95% confidence interval 16% to
71%). Health status scores that improved significantly more in
experimental subjects were mental health (0.58 SD; 0.07 to 1.10), role
limitations due to emotional problems (0.95 SD; 0.11 to 1.79), and
social functioning (0.65 SD; 0.03 to 1.26). Experimental subjects also
significantly reduced their illegal income and drug expenses and
committed fewer drug and property related offences. There were no
benefits in terms of work, housing situation, somatic health status,
and use of other drugs. Unexpectedly, only nine (38%) control subjects
entered the heroin maintenance programme at follow up.
Conclusions: A heroin maintenance programme is a
feasible and clinically effective treatment for heroin users who fail in conventional drug treatment programmes. Even in this population, however, another attempt at methadone maintenance may be successful and
help the patient to stop using injectable opioids.
