Optimizing HIV Pre-exposure Prophylaxis (PrEP) Among Women Who Use Drugs in Tanzania

Plain-language summary

This study is testing two different approaches to help women who use drugs in Tanzania take and continue using HIV prevention medication called pre-exposure prophylaxis (PrEP). Women who use drugs face a higher risk of HIV infection, but many do not start or continue PrEP due to barriers like stigma, mental health challenges, and lack of support. The study will enroll 200 women who use drugs in Dar es Salaam, Tanzania. These women will be randomly assigned to one of three groups: Motivational Interviewing for PrEP (MI-PrEP) Only - Women in this group will receive two one-hour counseling sessions focused on HIV prevention, PrEP education, and problem-solving to help the women start and continue using PrEP. Common Elements Treatment Approach (CETA) + MI-PrEP - Women in this group will receive the same MI-PrEP counseling sessions plus additional mental health counseling (up to 14 sessions) tailored to the women's individual needs, addressing issues like depression, anxiety, trauma, and substance use. Treatment as Usual (TAU) - Women in this group will receive basic information on PrEP, mental health, and harm reduction, along with optional referrals to PrEP or drug treatment clinics. The study will evaluate feasibility of administering MI-PrEP and CETA+MI-PrEP and how well these interventions help women start and stay on PrEP, as well as the intervention's impact on mental health and drug use. Researchers will also interview participants and counselors to understand the participants and counselors experiences with the program. The goal is to find effective ways to support PrEP use among women who use drugs and to develop a model that could be used in similar settings to reduce HIV risk. This pilot study is approved by ethics committees in the United States and Tanzania, and results will be shared with communities, policymakers, and researchers.
