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

Participants will receive MI-PrEP only will receive two 1-hour sessions with an intervention counselor. The first session will include information on PrEP and other HIV prevention and harm reduction strategies, and discussion on PrEP contemplation, importance, and confidence, and problem-solving around identified barriers to PrEP. The session will also include information on other available harm reduction strategies and services, including medications for opioid use disorder. The second session will focus on following up on any PrEP actions taken, challenges encountered, and problem-solving to address any challenges. Those ready to be linked to PrEP and/or harm reduction services will be offered an escort to a designated PrEP and/or opioid treatment clinic site or other harm reduction services.

Participants will receive CETA+MI-PrEP will receive 7 to 14 weekly one-hour sessions from an intervention counselor. Similar to the MI-PrEP group, women in this study arm will receive the two 1-hour MI-PrEP sessions with an intervention counselor with linkages to PrEP and/or harm reduction services. Women will then begin CETA sessions. The CETA intervention component is a modular and flexible approach comprised of nine elements that can be combined in various ways, including different sequences, to address clients' presenting symptoms and problem areas. CETA currently includes key engagement strategies, including MI, throughout the intervention. The intervention counselor will determine the specific intervention component sessions, sequence of sessions, and dose, or frequency of sessions, based on the primary problem area identified by the participant and intervention counselor as reported in the baseline assessment survey and initial discussions.
