INTEGRA: A Vanguard Study of Health Service Delivery in a Mobile Health Delivery Unit

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the efficacy of using a mobile health delivery unit (mobile unit) to deliver one stop integrated health services - particularly medication for opioid use disorder (MOUD) and medication for HIV treatment and prevention - to people who inject drugs (PWID) with opioid use disorder (OUD) to improve uptake and use of MOUD, and uptake and use of antiretroviral therapy (ART) or pre-exposure prophylaxis (PrEP).

Detailed Description
-----------------
The purpose of this study is to determine the efficacy of using a mobile health delivery unit (mobile unit) to deliver one stop integrated health services - particularly medication for opioid use disorder (MOUD) and medication for HIV treatment and prevention - to people who inject drugs (PWID) with opioid use disorder (OUD) to improve uptake and use of MOUD, and uptake and use of antiretroviral therapy (ART) or pre-exposure prophylaxis (PrEP). The intervention arm receiving health services in the mobile unit will be supported by peer navigation. An active control arm will receive peer navigation to health services available at community-based agencies. Impact (cost-effectiveness, mathematical modeling) and implementation factors (mixed methods to identify barriers and facilitators of the interventions) will contextualize findings from the efficacy analysis. The impact of the COVID-19 epidemic in the study population will also be assessed.
