Strengthening Addiction Care Continuum Through Community Consortium in Vietnam

The study will develop and test an intervention to strengthen a continuum of addiction services. The intervention, entitled "Community Care Consortium (CCC)," features community health workers' joint effort with family members to provide patient-centered, individualized addiction care and support. The intervention will be developed and tested through three phases in three regions of Vietnam (Ninh Binh, Da Nang, and Can Tho).

In Phase 1, we will conduct formative studies with commune (community) health workers (CHW), community representatives, PWUD, and their family members to identify barriers to addiction service utilization and discuss potential strategies to establish a continuum of addiction services. Based on the formative study findings, the CCC Intervention and its implementation plans will be developed through workgroup meetings with researchers, community members, and target users.

In Phase 2, the CCC Intervention will be piloted in three communes and revised based on acceptability/feasibility data, process evaluation, and feedback from field staff and participants.

In Phase 3, a randomized controlled trial of the CCC Intervention will be conducted in 60 communes, which will be randomized to either an intervention condition or a control condition (30 communes in each condition). A total of 720 PWUD, 720 of their family members, and 180 commune health workers (CHW) will participate in the study. The intervention outcomes on PWUD, CHW, and family members will be assessed with the data collected at baseline, 3-, 6-, 9- and 12-month follow-ups.
