Globally, organization and system-level interventions are needed to provide integrated services to address the needs of People Living with HIV who use drugs (PLHWUD) and other comorbid conditions. The community health and service workforce can be mobilized to promote service integration, which is particularly critical in low- and middle-income countries.

The proposed study will develop and pilot test multilevel integration strategies in Vietnam, including structural changes for better treatment coordination, strengthening treatment-provider networks for improved service collaboration, and involving community health workers (CHW) to support those in need throughout the treatment cascade. The study will be conducted in six provinces in Vietnam. Agency-level aggregated data will be collected and compared at the baseline and at 12 months after the intervention. In Phase 2b, we will implement and pilot test our intervention strategies that focus on CHW working at commune health centers (CHC) to enhance their networking and collaboration with providers at the treatment facilities. The intervention will also focus on improving CHW communication skills to support PLHWUD treatment initiation, retention, and adherence.
