Community Health Worker And MHealth to ImProve Viral Suppression

Study Overview
=================
Brief Summary
-----------------
The overall goal of this study is to evaluate the effects of the CHAMPS intervention for people living with HIV (PLWH) in a randomized controlled trial. The proposed trial is scientifically significant in representing a principled and systematic effort to test the efficacy of a combined community health worker (CHW) and smartphone intervention linked to a smart pill box for antiretroviral (ART) adherence in PLWH in the United States (US). Guided by a rigorous theoretical model of supportive accountability and building on preliminary work, this intervention has the potential to enable PLWH to self-manage their ART regimens while CHW monitor their ART adherence in real-time ultimately leading to viral suppression and ART adherence.

Detailed Description
-----------------
Persons living with HIV (PLWH) now achieve a near-normal life expectancy due to antiretroviral therapy (ART) which has transformed HIV from a terminal diagnosis to a manageable chronic condition. Despite widespread availability of ART in the United States (US), many of the country's approximate 1.1 million PLWH are not fully benefitting from ART due to poor adherence. These suboptimal HIV health outcomes occur at a time when clinicians have limited time and the US healthcare system remains fragmented, further exacerbating the challenges inherent in the lives of underserved, marginalized groups, such as PLWH. Therefore, the development and evaluation of interventions using a cadre of community health workers (CHW) holds promise for addressing these challenges in the US. This study addresses limitations in current research on CHW interventions to improve viral suppression and ART adherence. The investigators propose to build on strong preliminary data to strengthen a community health worker (CHW) intervention using an existing mHealth approach, and provide further information regarding the successful wide-scale implementation of this combination intervention.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Viral Load | Using blood samples obtained during study visits, viral load levels will be used to asses ART adherence. | Baseline, 6 month follow up, 12 month follow up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in ART adherence - CleverCap | The CleverCapTM dispenser will automatically record each time a participant opens the dispenser. The investigators will collect adherence data each day from the start to the end of trial (day 1 to 12 months), and it is a count response (number of times taking medication each day). | Up to 12 months | 
| Change in Score on the Self-Rating Scale Item (SRSI) | The Self-Rating Scale Item is a single-item self-report adherence measure that uses a 5-point Likert scale to describe medication adherence over the past 4 weeks. Scores range from 1(very poor) to 6 (excellent). | 6 month follow up, 12 month follow up |
