The purpose of this study is to compare two implementation approaches [Standard Approach (SA) vs. Tailored Approach (TA)] for scaling-up the evidence-based systems navigation and psychosocial counseling integrated intervention (SNaP) in HIV test sites in Vietnam.


This is a cluster randomized, controlled implementation trial to compare two implementation approaches (standard and tailored) for scaling-up the SNaP intervention in 42 HIV test sites in Vietnam. The SNaP intervention combines systems navigation and psychosocial counseling for people who inject drugs (PWID), and it is designed to facilitate PWID's engagement in HIV and substance use care.

The two implementation approaches being compared are:

  • Standard Approach (SA); vs.
  • Tailored Approach (TA)

SNaP is an evidence-based intervention (EBI) that combines systems navigation and psychosocial counseling to facilitate the engagement of HIV-infected people who inject drugs (PWID) into HIV and substance use care.

The 42 HIV test sites will be randomized in a 1:1 ratio to either the standard approach (SA) procedure or a tailored approach (TA).

At the HIV test sites, the study will enroll:

  • Approximately 6200 HIV-infected PWID who are newly diagnosed and not currently on antiretroviral therapy (ART), who consent for medical record assessments. Of those PWID enrolled, a subsample cohort of 1500 PWID will also be enrolled for detailed assessments, including viral load determination, at baseline, 12 and 24 months.
  • HIV test site director boards and staff.

Study activities will span across 5 years, with approximately 27 months at each site and recruitment of PWID participants over 21 months. For PWID not in the subsample cohort, participation is a one-time visit. For the subsample cohort PWID or PWID selected for qualitative interviews, maximum study participation time is 24-27 months. For HIV test site director boards and staff, maximum time in the study is 24-27 months.
