Study of Integrating Antiretroviral Therapy With Methadone Treatment for People Who Inject Drugs — IMAT  

HIV Clinical Trial

Official title: Reducing Failure-to-Initiate ART Among People Who Inject Drugs: the IMAT Strategy

Status Enrolling by invitation

Clinical Trial Summary

To improve ART initiation among people who inject drugs, the investigators propose to develop and pilot a multi-component Integrated Methadone and Antiretroviral Therapy strategy (IMAT) in Dar es Salaam, Tanzania. In doing so, the investigators anticipate building a functional model of methadone and ART integration that improves the effectiveness and efficiency of service delivery.

Clinical Trial Description

The overarching goal of the proposed research is to develop and test an innovative implementation model (IMAT) for the effective integration of HIV care and treatment with methadone services in Dar es Salaam, Tanzania. The investigators will utilize the PRECEDE framework to inform the intervention to improve linkage of HIV-positive methadone patients to ART. This model suggests that strategies intended to improve health care delivery should consider a combination of three factors: 1) 'predisposing factors' - characteristics such as knowledge, attitudes, beliefs and motivation to change, 2) 'enabling factors' - characteristics that enable someone to act on their desired behavior and 3) 'reinforcing factors' - factors that encourage repetition or persistence of behavior. Therefore, our IMAT approach uses 1) targeted education and mentoring for providers that predispose them to timely ART initiation, 2) POC CD4 count platforms (PIMA, Alere) providing real-time screening and results that enable ART initiation and 3) an alerts and reminder dashboard (e.g., a summary of key indicators for improved decision making) for providers that reinforce ART initiation. Additionally, our approach will lay the foundation for developing implementation strategies for future point-of-care technologies such as viral load.

The study will combine a mixture of qualitative and quantitative methodologies to inform and evaluate the IMAT intervention.

A baseline qualitative study using in-depth interviews will be conducted among providers and methadone clients to understand predisposing, enabling and reinforcing factors related to integration of HIV care and treatment into the methadone clinic. Information gained from these qualitative assessments will inform and support the IMAT strategy. In addition, HIV-positive methadone clients will be randomly selected to complete a baseline cross-sectional survey to collect data on patient satisfaction, access to HIV care, current treatment navigation access, and HIV care literacy.

The investigators will assess the effectiveness of IMAT with a quasi-experimental pre-post cohort design and a pre-post cross-sectional survey to examine changes in patient- and provider-level outcomes after implementation of IMAT compared to before IMAT. In addition, The investigators will assess the feasibility and acceptability of the IMAT strategy using a post-implementation cross-sectional survey with a particular emphasis on satisfaction with services; a time motion study to understand the timeliness of care provision; and in-depth interviews with patients and providers to understand experiences with the IMAT strategy. ;
