RESUMEN

BACKGROUND: HIV risk remains unacceptably high among adolescent girls and young women (AGYW) in southern and eastern Africa, reflecting structural and social inequities that drive new infections. In 2015, PEPFAR (the United States President's Emergency Plan for AIDS Relief) with private-sector partners launched the DREAMS Partnership, an ambitious package of interventions in 10 sub-Saharan African countries. DREAMS aims to reduce HIV incidence by 40% among AGYW over two years by addressing multiple causes of AGYW vulnerability. This protocol outlines an impact evaluation of DREAMS in four settings. METHODS: To achieve an impact evaluation that is credible and timely, we describe a mix of methods that build on longitudinal data available in existing surveillance sites prior to DREAMS roll-out. In three long-running surveillance sites (in rural and urban Kenya and rural South Africa), the evaluation will measure: (1) population-level changes over time in HIV incidence and socio-economic, behavioural and health outcomes among AGYW and young men (before, during, after DREAMS); and (2) causal pathways linking uptake of DREAMS interventions to 'mediators' of change such as empowerment, through to behavioural and health outcomes, using nested cohort studies with samples of ~ 1000-1500 AGYW selected randomly from the general population and followed for two years. In Zimbabwe, where DREAMS includes an offer of pre-exposure HIV prophylaxis (PrEP), cohorts of young women who sell sex will be followed for two years to measure the impact of 'DREAMS+PrEP' on HIV incidence among young women at highest risk of HIV. In all four settings, process evaluation and qualitative studies will monitor the delivery and context of DREAMS implementation. The primary evaluation outcome is HIV incidence, and secondary outcomes include indicators of sexual behavior change, and social and biological protection. DISCUSSION: DREAMS is, to date, the most ambitious effort to scale-up combinations or 'packages' of multi-sectoral interventions for HIV prevention. Evidence of its effectiveness in reducing HIV incidence among AGYW, and demonstrating which aspects of the lives of AGYW were changed, will offer valuable lessons for replication.

RESUMEN

OBJECTIVES: There are concerns that medical pluralism may delay patients' progression through the HIV cascade-of-care. However, the pathways of impact through which medical pluralism influence the care of people living with HIV (PLHIV) in African settings remain unclear. We sought to establish the manifestation of medical pluralism among PLHIV, and explore mechanisms through which medical pluralism contributes bottlenecks along the HIV care cascade. METHODS: We conducted a multicountry exploratory qualitative study in seven health and demographic surveillance sites in six eastern and southern African countries: Uganda, Kenya, Tanzania, Malawi, Zimbabwe and South Africa. We interviewed 258 PLHIV at different stages of the HIV cascade-of-care, 48 family members of deceased PLHIV and 53 HIV healthcare workers. Interviews were conducted using shared standardised topic guides, and data managed through NVIVO 8/10/11. We conducted a thematic analysis of healthcare pathways and bottlenecks related to medical pluralism. RESULTS: Medical pluralism, manifesting across traditional, faith-based and biomedical health-worlds, contributed to the care cascade bottlenecks for PLHIV through three pathways of impact. First, access to HIV treatment was delayed through the nature of health-related beliefs, knowledge and patient journeys. Second, HIV treatment was interrupted by availability of alternative options, perceived failed treatment and exploitation of PLHIV by opportunistic traders and healers. Lastly, the mixing of biomedical healthcare providers and treatment with traditional and faith-based options fuelled tensions driven by fear of drug-to-drug interactions and mistrust between providers operating in different health-worlds. CONCLUSION: Medical pluralism contributes to delays and interruptions of care along the HIV cascade, and mistrust between health providers. Region-wide interventions and policies are urgently needed in sub-Saharan Africa to minimise potential harm and consequences of medical pluralism for PLHIV. The role of sociocultural beliefs in mediating bottlenecks necessitate adoption of culture-sensitive approaches intervention designs and policy reforms appropriate to the context of sub-Saharan Africa.

RESUMEN

BACKGROUND: A prior randomized control trial showed financial incentives increase HIV testing rates for children of unknown HIV status. Translating evidence-based interventions such as these to scale requires an implementation science approach. METHODS: A qualitative study evaluating health care providers' perceptions of barriers and facilitators of a previously completed financial incentives intervention for pediatric HIV testing was conducted at health care facilities in Kisumu, Kenya. Six focus group discussions with 52 providers explored determinants of acceptability, feasibility, and sustainability of financial incentive scale-up for pediatric HIV testing using the Consolidated Framework for Implementation Research to inform question guides and thematic analysis. RESULTS: Providers found the use of financial incentive interventions for pediatric HIV testing to be highly acceptable. First, providers believed financial incentives had a relative advantage over existing strategies, because they overcame cost barriers and provided additional motivation to test; however, concerns about how financial incentives would be implemented influenced perceptions of feasibility and sustainability. Second, providers expressed concern that already overburdened staff and high costs of financial incentive programs would limit sustainability. Third, providers feared that financial incentives may negatively affect further care because of expectations of repeated financial support and program manipulation. CONCLUSIONS: Providers viewed financial incentives as an acceptable intervention to scale programmatically to increase uptake of pediatric testing. To ensure feasibility and sustainability of financial incentives in pediatric HIV testing programs, it will be important to clearly define target populations, manage expectations of continued financial support, and establish systems to track testing.

RESUMEN

BACKGROUND: The 'DREAMS Partnership' promotes a multi-sectoral approach to reduce adolescent girls and young women's (AGYW) vulnerability through a core package of interventions targeting multiple sources of HIV risk-to promote Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS) lives. Implementation of such multi-sectoral programmes is complex and requires adaptation to national and local contexts. We describe the early implementation of DREAMS in diverse settings, to identify lessons for the scale-up and replication of combination programmes for young people. METHODS: As part of evaluations underway in six DREAMS sites in three countries (Kenya, South Africa and Zimbabwe), we draw on process evaluation data collected from focus group discussions, key informant interviews, and in-depth interviews with beneficiaries, parents/caregivers, programme managers and opinion leaders. Additionally, structured observations were conducted and Gantt charts completed upon consultation with implementers. We concurrently reviewed documentation available on DREAMS and held cross-site discussions to interpret findings. FINDINGS: All sites sought to implement all components of the DREAMS core package, but how and when they were implemented varied by context. Models of delivery differed, with either multiple or single partners responsible for some or all interventions. Key challenges included the urgent and ambitious expectations of DREAMS; 'layering' multiple interventions across different sectors (health, education, social welfare); supporting individuals' journeys between services to improve uptake and retention; engaging communities beyond direct beneficiaries; avoiding perceived/actual exclusivity; and ensuring continuity of commitment and funding for DREAMS. Despite significant challenges, DREAMS was well-received in the communities and perceived by both beneficiaries and implementers to empower AGYW to remain HIV negative. Structures, protocols and tools were introduced to strengthen referrals and deliver services targeted to the age and circumstances of young people. CONCLUSIONS: The benefits of combinations or integrated 'packages' of interventions are increasingly recognised. Early implementation of DREAMS provides useful lessons for improving coordination across multiple partners using a phased, systematic approach, regular adaptions to each unique context, and ensuring community ownership.
