Human Immunodeficiency Virus Clinical Trial
Official title:
A Stepped Care, Peer-Delivered Intervention to Improve ART Adherence and SUD in Primary Care
The purpose of this study is to evaluate a stepped care behavioral intervention for HIV medication adherence and substance use ("Khanya") integrated into an HIV primary care setting in South Africa. The intervention is specifically designed to be implemented by non-specialist counselors with lived substance use experience (i.e., peers), using a task sharing, stepped care model in local primary care clinics. The Khanya stepped care package will be compared to usual care, enhanced with referral to a local outpatient substance use treatment program (Enhanced Standard of Care - ESOC) over 12 months.
South Africa is home the highest number of people living with HIV in the world and has a high burden of substance use disorder (SUD). Globally, a SUD treatment gap exists, particularly in low and middle-income countries (LMICs), such as South Africa, where only 1-4% of individuals receive minimally adequate treatment. Workforce shortages are also severe in LMICS, and countries such as South Africa have responded to this through the implementation of task sharing models to expand access to antiretroviral therapy (ART) and mental health services. However, efforts to implement task shared, SUD treatment and ART adherence interventions that can be feasibly and sustainably integrated into primary care are limited. Therefore, the purpose of this study is to help fill this gap in care by evaluating Khanya, a peer-delivered, behavioral intervention to improve HIV care outcomes and reduce substance use. The present study is a hybrid effectiveness-implementation trial designed to evaluate Khanya compared to usual care, enhanced with referral to a local outpatient substance use treatment program (Enhanced Standard of Care - ESOC) over 12 months. To provide care for those most in need, participants will be patients with HIV who are struggling with ART adherence and have elevated SUD risk. In this study, Khanya will be delivered as a stepped-care package in which the least resource-intensive part of the intervention (i.e., a single session problem solving intervention for HIV medication adherence) will be delivered first. Only individuals randomized to the Khanya intervention who are still struggling with HIV medication adherence after the first session will be stepped up to receive the more comprehensive, resource-intensive part of the intervention (i.e., six additional sessions of the intervention). Primary effectiveness outcomes in this clinical trial include ART adherence and SUD. ;
