NCT02440256

Brief Summary

Opioid Substitution Treatment (OST) provides a critical opportunity for HIV testing and linkage to antiretroviral treatment. The EHOST study will evaluate a prescriber-focused intervention to increase HIV testing rates, and optimize antiretroviral treatment, re-engagement and retention outcomes among individuals engaged in OST. 46 OST sites in British Columbia will be randomly allocated into three clusters. Clusters will initiative the intervention at different time points, or steps, with every cluster receiving the intervention.

Outcome Measures

Primary Outcomes (3)

  • The HIV testing rate among those not known to be HIV positive

    24 months

  • The rate of Highly Active Antiretroviral (HAART) initiation among those not on HAART

    24 months

  • The rate of HAART adherence among those on HAART

    24 months

Study Arms (3)

Cluster 1

OTHER

Cluster 1 is the first OST cluster (with an estimated 15-16 OST sites) to receive the 'Expanded HIV care in Opioid Substitution Treatment' intervention, to be administered during the sixth month of the trial. Cluster 1 will be a 'no intervention' arm in the first 6 months of the study, and will cross-over to an experimental arm for months 6-24.

Other: Expanded HIV care in Opioid Substitution Treatment

Cluster 2

OTHER

Cluster 2 is the second OST cluster (with an estimated 15-16 OST sites) to receive the 'Expanded HIV care in Opioid Substitution Treatment' intervention, to be administered during the twelfth month of the trial. Cluster 2 will be a 'no intervention' arm in the first 12 months of the study, and will cross-over to a experimental arm for month 12-24.

Other: Expanded HIV care in Opioid Substitution Treatment

Cluster 3

OTHER

Cluster 3 is the final OST cluster (with an estimated 15-16 OST sites) to receive the 'Expanded HIV care in Opioid Substitution Treatment' intervention, to be administered during the 18th month of the trial. As such, Cluster 3 will be a 'no intervention' arm in the first 18 months of the study, and will cross-over to an experimental arm for months 18-24.

Other: Expanded HIV care in Opioid Substitution Treatment

Interventions

The EHOST intervention entails in-person presentations and consultation sessions with individual OST sites that will: (i) provide rationale for the study (ii) outline action items of the intervention; and (iii) describe guidelines around HIV testing and care. The EHOST intervention will be delivered at three distinct times: (i) at point of OST entry; (ii) following 7 days non-adherence; and (iii) at bi-annual intervals. The interventions are comprised of HIV test offers for individuals of unknown HIV status; offers of HIV-related care, including cluster of differentiation 4 (CD4), plasma viral load (pVL) and resistance tests, along with HAART initiation for those known to be HIV-positive, not on HAART; and regular monitoring for those known to be HIV positive, on HAART.
