Scaling up an Evidence-based Intervention for Antiretroviral Therapy for PWID in Vietnam: an Implementation Trial

The multifaceted implementation strategies for SA sites were identified through centralized Intervention Mapping. Before SNaP implementation starts, the specific set of one-size-fits-all implementation strategies was determined through a formal process with investigators, government stakeholders, and clinical representatives.

The Tailored Approach includes the multifaceted strategy that will be offered to the Standard Approach condition. It will also be tailored to match site-specific barriers to implementation of SNaP at that site. The strategy for TA sites involves a 2-day site-specific training, monthly coaching calls, and an external technical assistance hotline to help organizations to tailor implementation strategies to address their site-specific needs. At the 2-day TA training, the TA sites will be guided on developing site-specific implementation plans, in which they may use additional implementation strategies that they have identified themselves or selected from a list developed by the central team.
