Delivery of index-linked HIV testing for children: learnings from a qualitative process evaluation of the B-GAP study in Zimbabwe.

BACKGROUND: Index-linked HIV testing for children, whereby HIV testing is offered to children of individuals living with HIV, has the potential to identify children living with undiagnosed HIV. The "Bridging the Gap in HIV Testing and Care for Children in Zimbabwe" (B-GAP) study implemented and evaluated the provision of index-linked HIV testing for children aged 2-18 years in Zimbabwe. We conducted a process evaluation to understand the considerations for programmatic delivery and scale-up of this strategy. METHODS: We used implementation documentation to explore experiences of the field teams and project manager who delivered the index-linked testing program, and to describe barriers and facilitators to index-linked testing from their perspectives. Qualitative data were drawn from weekly logs maintained by the field teams, monthly project meeting minutes, the project coordinator's incident reports and WhatsApp group chats between the study team and the coordinator. Data from each of the sources was analysed thematically and synthesised to inform the scale-up of this intervention. RESULTS: Five main themes were identified related to the implementation of the intervention: (1) there was reduced clinic attendance of potentially eligible indexes due to community-based differentiated HIV care delivery and collection of HIV treatment by proxy individuals; (2) some indexes reported that they did not live in the same household as their children, reflecting the high levels of community mobility; (3) there were also thought to be some instances of 'soft refusal'; (4) further, delivery of HIV testing was limited by difficulties faced by indexes in attending health facilities with their children for clinic-based testing, stigma around community-based testing, and the lack of familiarity of indexes with caregiver provided oral HIV testing; (5) and finally, test kit stockouts and inadequate staffing also constrained delivery of index-linked HIV testing. CONCLUSIONS: There was attrition along the index-linked HIV testing cascade of children. While challenges remain at all levels of implementation, programmatic adaptations of index-linked HIV testing approaches to suit patterns of clinic attendance and household structures may strengthen implementation of this strategy. Our findings highlight the need to tailor index-linked HIV testing to subpopulations and contexts to maximise its effectiveness.

Shortening "the Road" to Improve Engagement with HIV Testing Resources: A Qualitative Study Among Stakeholders in Rural Uganda.

In HIV-endemic areas, traditional healers are frequently used with, or instead of, biomedical resources for health care needs. Studies show healers are interested in and capable of supporting patients in the HIV care cascade. However, adults who receive care from healers have low engagement with HIV services. To achieve epidemic control, we must understand gaps between the needs of HIV-endemic communities and the potential for healers to improve HIV service uptake. This study's objective was to characterize stakeholder perspectives on barriers to HIV testing and approaches to mitigate barriers in a medically pluralistic, HIV-endemic region. This study was conducted in Mbarara District, a rural area of southwestern Uganda with high HIV prevalence. Participants included HIV clinical staff, traditional healers, and adults receiving care from healers. Fifty-six participants [N = 30 females (52%), median age 40 years (interquartile range, 32-51.5)] were recruited across three stakeholder groups for minimally structured interviews. Themes were identified using an inductive, grounded theory approach and linked together to create a framework explaining stakeholder perspectives on HIV testing. Stakeholders described the "road" to HIV testing as time-consuming, expensive, and stigmatizing. All agreed healers could mitigate barriers by delivering HIV testing at their practices. Collaborations between biomedical and traditional providers were considered essential to a successful healer-delivered HIV testing program. This work describes a novel approach to "shorten the road" to HIV testing, suggesting that traditional healer-delivered HIV testing holds promise to expand uptake of testing among communities with limited access to existing programs.
