An evaluation of opioid replacement pharmacotherapy in an urban Aboriginal Health Service.
OBJECTIVE
This study aimed to evaluate the opioid replacement pharmacotherapy at Winnunga Nimmityjah Aboriginal Health Service (Winnunga) in the Australian Capital Territory.


METHODS
Existing and new adult patients at Winnunga who were receiving opioid replacement pharmacotherapy were recruited. Twenty-one of 30 eligible patients participated in this cohort study. The Brief Treatment Outcome Measure was administered to patients twice with an interval of at least three months. Primary outcome measures were retention rate in the program and self-reported heroin use.


RESULTS
Eighty-one per cent (17/21) of patients remained in treatment at three months. Median self-reported heroin use for existing patients was 0 days/month at initial interview and follow-up (95% CI 0-1). There was no significant difference between self-reported heroin use at initial and follow-up interview (paired Wilcoxon test, R=10, alpha=0.05). Mean self-reported heroin use was 1.5 days/month at initial interview and 2.4 days/month at follow-up.


CONCLUSIONS
The retention rate of 81% and low levels of heroin use suggest that opioid replacement pharmacotherapy at Winnunga is comparable to the outcomes of mainstream treatment programs.


CONCLUSIONS
Opioid replacement pharmacotherapy is beneficial to opioid-dependent Aboriginal people in urban settings. Access to this treatment in culturally appropriate settings needs to be expanded.
