Adolescents and young adults (AYA) with HIV face unique challenges to engagement in care and their ability to achieve optimal health outcomes. The investigators hypothesize that developmentally-tailored behavioral interventions will improve engagement in HIV care and viral suppression (per current MOH guidelines) among AYA with HIV in Kenya. This two stage study will initially randomize 880 AYA with HIV to either standard of care (SOC) or electronic navigation to prevent treatment lapse. Participants who have a lapse will be re-randomized to SOC, in-person peer navigation, or conditional cash transfers. Formative work will be conducted initially to tailor the interventions to AYA and then later to assess AYA perception, experience, and satisfaction with the interventions. We will evaluate the most effective and cost-effective intervention and sequence of interventions to inform HIV program managers, public policy makers, and other key stakeholders the best approaches to improve engagement of care of AYA with HIV.
While the global response to HIV has reached close to 20 million persons with life-saving antiretroviral therapy (ART) and saved upwards of 60 million life-years, progress has been uneven and adolescents and young adults (AYA) aged 14-24 years represent a key group left behind. Compared to adults, AYA with HIV face more numerous, more diverse and more intense barriers to adherence and retention. The investigators will utilize a SMART study design in two stages among 880 AYA with HIV in Kenya to improve retention and viral suppression per the current MOH guidelines. In stage 1 AYA will be randomized 1:1 to either (1) standard of care education or counseling vs. (2) electronic navigation. Participants who do well (no lapses in retention, medication pick up and viral suppression) will be maintained on these low-intensity interventions, whereas those who fail will be re-randomized a second time to one of three re-engagement interventions (stage 2): (1) standard of care tracing, (2) a conditional cash transfer and (3) in-person peer navigation. The primary outcomes include (1) for prevention: lapse in engagement or viral non-suppression following current MOH guidelines; (2) for re-engagement: viral suppression six months after re-randomization; and (3) across six strategies: sustained viral suppression and sustained engagement in care at two years. The investigators anticipate that enrolling 880 AYA will result in 99% power to detect a 15% difference in the primary outcome between intervention groups. The investigators believe this study will yield evidence specific to AYA with HIV, quantify the relative magnitude of different sequenced interventions, capture the costs, and have direct relevance for public health programming to end the AIDS epidemic through engaging adolescents and young adults with HIV.

Standard of care - routine education and counseling (SOC-REC)/SOC-Outreach and Intensified Counseling (OIC). SOC-REC is a stage 1 intervention to prevent lapses in HIV engagement through routine care. If an adolescent (1) misses an appointment \>14 days, or (2) who have unsuppressed HIV RNA as per current MOH viral load threshold or (3) clinically documented non-adherence after \>3 months of treatment he/she is re-randomized to a stage 2 intervention. SOC-OIC is a stage 2 intervention to treat lapses in HIV engagement through routine care which may include tracing and counseling to return to the clinic.
SOC-REC/Conditional Cash Transfer (CCT). SOC-REC is a stage 1 intervention to prevent lapses in HIV engagement through routine care. If an adolescent (1) misses an appointment \>14 days, or (2) who have unsuppressed HIV RNA as per current MOH viral load threshold or (3) clinically documented non-adherence after \>3 months of treatment he/she is re-randomized to a stage 2 intervention. CCT is a stage 2 intervention to treat lapses in HIV engagement by providing a small cash incentive for on-time clinic attendance and/or viral load suppression (following per current MOH guidelines).
SOC-REC/In-Person Peer Navigation (IP-NAV). SOC-REC is a stage 1 intervention (routine care) to prevent lapses in HIV engagement. If an adolescent (1) misses an appointment \>14 days, or (2) who have unsuppressed HIV RNA as per current MOH viral load threshold or (3) clinically documented non-adherence after \>3 months of treatment he/she is re-randomized to a stage 2 intervention. IP-NAV is a stage 2 intervention to treat lapses in HIV engagement. Trained peer navigators will develop rapport with the participants and provide psychosocial support, case management, and assess retention and adherence barriers in a systematic manner and work with the participant to develop social support and clear, feasible plans to address barriers. The peer navigator will meet with the participant at least monthly, and no more than weekly, until HIV care engagement is demonstrated.
E-Nav is a stage 1 intervention to prevent lapses in HIV engagement. Trained e-peer navigators will develop rapport and provide support through phone calls and/or patient preferred social media platforms. They will meet once in person and then weekly electronically for 8 weeks, and then monthly. If an adolescent (1) misses an appointment \>14 days, or (2) who have unsuppressed HIV RNA as per current MOH viral load threshold or (3) clinically documented non-adherence after \>3 months of treatment he/she is re-randomized to a stage 2 intervention.
