PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0003588.

Abstract
Caregiver-assisted testing using HIV self-test (CG-HIVST) kits has been proposed to enhance paediatric HIV case finding and contribute toward ending paediatric HIV/AIDS by 2030. We conducted a systematic review to assess the risks and benefits of CG-HIVST. We searched nine electronic databases and consulted experts to identify relevant articles through 5 February, 2022. Studies comparing CG-HIVST to other testing services among children over 18-months, or to no intervention, were included. Outcomes included uptake, acceptability, diagnostic accuracy, feasibility, HIV positivity, linkage to care, social harm, values and preferences, costs, and cost-effectiveness. Risk of bias was assessed using relevant Cochrane tools and certainty of evidence was evaluated with GRADE. Among 2203 screened articles, nine observational studies from sub-Saharan Africa were included. All studies used and assessed caregiver-assisted testing using oral fluid-based HIVST. In one non-randomized intervention study of 6062 children, overall CG-HIVST uptake was lower than other standard testing services (3.30% vs. 56.71%). In the same study, HIV positivity following CG-HIVST appeared lower or comparable to standard testing (RR = 0.44; 95% CI: 0.06, 3.20). Two single-arm studies reported high linkage to confirmatory testing (97.48%) and treatment initiation (97.7%) among children reported positive with CG-HIVST. Pooled positive predictive value was 36.72% across three non-randomized intervention studies. Reported social harms were rare, and acceptability appeared high among caregivers taking up the intervention, but feasibility was unclear as some reported anxiety in relation to reactive results. Evidence was appraised very low certainty. Average CG-HIVST costs varied widely and were consistently higher than standard testing services. CG-HIVST may be acceptable, but feasibility remains uncertain with potential higher costs. Current evidence favours standard testing for uptake and positivity. Low positive predictive values raise concerns about false positives and potential harm. Programmes should prioritize evidence-based approaches for paediatric case-finding, while research to fully evaluate this approach continues.

Abstract
PURPOSE OF REVIEW Expanding access to HIV testing services and linking newly diagnosed positive adolescents to antiretroviral therapy is critical to epidemic control. However, testing coverage and treatment initiation rates continue to lag behind adult counterparts. This article synthesizes evidence on facilitative policies and service delivery practices focused on adolescents to inform programming. RECENT FINDINGS Our narrative review found that national policies are growing more adolescent-inclusive but barriers around the age of consent, waiver frameworks and dissemination constrain translate into practice. Facility-based provider-initiated testing through integrated sexual health services and dedicated youth centres demonstrates uptake effectiveness if confidentiality and youth-friendly adaptations are assured. Supportive policies, youth-responsive adaptations across testing models and strengthening age-disaggregated monitoring are vital to improving adolescents' engagement across the HIV testing and treatment cascade. Further implementation research is imperative to expand the reach of adolescent HIV testing in sub-Saharan Africa.

Abstract
Introduction Point-of-Care Tests (POCTs) are utilized daily in resource abundant regions, however, are limited in the global south, particularly in the prehospital setting. Few studies exist on the use of non-malarial POCTs by Community Health Workers (CHWs). The purpose of this scoping review is to delineate the current diversity in and breadth of POCTs evaluated in the prehospital setting. Methods A medical subject heading (MeSH) analysis of known key articles was done by an experienced medical librarian and scoping searches were performed in each database to capture "point of care testing" and "community health workers." This review was guided by the PRISMA Extension for scoping reviews. Results 2735 publications were returned, 185 were nominated for full-text review, and 110 studies were confirmed to meet study criteria. Majority focused on malaria (74/110; 67%) or HIV (25/110; 23%); 9/110 (8%) described other tests administered. Results from this review demonstrate a broad geographic range with significant heterogeneity in terminology for local CHWs. Conclusion The use of new POCTs is on the rise and may improve early risk stratification in limited resource settings. Current evidence from decades of malaria POCTs can guide future implementation strategies.

Abstract
Objective To estimate the feasibility, positivity rate and cost of offering child testing for human immunodeficiency virus (HIV) to mothers living with HIV attending outpatient clinics in Burkina Faso. Methods We conducted this implementation study in nine outpatient clinics between October 2021 and June 2022. We identified all women ≤ 45 years who were attending these clinics for their routine HIV care and who had at least one living child aged between 18 months and 5 years whose HIV status was not known. We offered these mothers an HIV test for their child at their next outpatient visit. We calculated intervention uptake, HIV positivity rate and costs. Findings Of 799 eligible children, we tested 663 (83.0%) and identified 16 new HIV infections: 2.5% (95% confidence interval, CI: 1.5-4.1). Compared with HIV-negative children, significantly more HIV-infected children were breastfed beyond 12 months (P-value: 0.003) and they had not been tested before (P-value: 0.003). A significantly greater proportion of mothers of HIV-infected children were unaware of the availability of child testing at 18 months (P-value: < 0.001) and had more recently learnt their HIV status (P-value: 0.01) than mothers of HIV-negative children. The intervention cost 98.1 United States dollars for one child testing HIV-positive. Barriers to implementing this strategy included shortages of HIV tests, increased workload for health-care workers and difficulty accessing children not living with their mothers. Conclusion Testing HIV-exposed children through their mothers in outpatient clinics is feasible and effective in a low HIV-prevalence setting such as Burkina Faso. Implementation of this strategy to detect undiagnosed HIV-infected children is recommended.

Abstract
BACKGROUND Globally, two out of five children living with HIV (CLHIV) are unaware of their HIV status, and a little more than 50% are receiving antiretroviral therapy (ART). This paper describes case-finding strategies and their contribution to identifying CLHIV and linking them to ART in Nigeria. METHODS This before-after study used program data abstracted during the implementation of different paediatric-focused strategies (provider-initiated testing and counselling, orphans and vulnerable children testing, family-based index testing, early infant diagnosis (EID), community-driven EID, and community-based testing) delivered in health facilities and in communities to improve HIV case identification. Data were abstracted for children (0 to 14 years) who received HIV testing services and were initiated on ART in Akwa Ibom State, Nigeria during the pre-implementation period (April-June 2021) and during the implementation period (July-September 2021). Descriptive statistics were used to describe the testing coverage, positivity rate (proportion of tests that were positive for HIV), linkage to ART, and ART coverage, by age, sex, and testing modality. Interrupted time series analysis (ITSA) on STATA 14 was used to estimate the effect of the implementation of these strategies on HIV testing uptake and positivity rate at a 0.05 significance level. RESULTS A total of 70,210 children were tested for HIV within the six-month period, and 1,012 CLHIV were identified. A total of 78% (n = 54,821) of the tests and 83.4% (n = 844) CLHIV were diagnosed during the implementation period. During implementation, the HIV positivity rate increased from 1.09% (168/15,389) to 1.54% (844/54,821), while linkage to ART increased from 99.4% (167/168) to 99.8% (842/844). The contribution from community-based modalities to CLHIV identified increased from 63% (106/168) to 84% (709/844) during the implementation, with the majority, 60.8% (431/709), from community-based index testing. Overall, ART coverage increased from 39.7 to 55.6% at the end of the intervention period. CONCLUSION The findings show that expanding differentiated HIV testing approaches provided mostly in the community significantly increased pediatric case identification. However, ART coverage remains low, especially for younger age groups, and requires further efforts.

Delivery of index-linked HIV testing for children: learnings from a qualitative process evaluation of the B-GAP study in Zimbabwe. BMC Infect Dis 2023; 23:262. [PMID: 37101147 PMCID: PMC10131435 DOI: 10.1186/s12879-023-08088-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Accepted: 02/16/2023] [Indexed: 04/28/2023] Open
Abstract
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.

Abstract
Purpose of Review HIV testing is the critical first step to direct people living with HIV (PLWH) to treatment. However, progress is still being made towards the UNAIDS benchmark of 95% of PLWH knowing their status by 2030. Here, we discuss recent interventions to improve HIV testing uptake in global settings. Recent Findings Successful facility-based HIV testing interventions involve couples and index testing, partner notification, and offering of incentives. Community-based interventions such as home-based self-testing, mobile outreach, and hybrid approaches have improved HIV testing in low-resource settings and among priority populations. Partnerships with trusted community leaders have also increased testing among populations disproportionally impacted by HIV. Summary Recent HIV testing interventions span a breadth of facility- and community-based approaches. Continued research is needed to engage men in sub-Saharan Africa, people who inject drugs, and people who avoid biomedical care. Interventions should consider supporting linkage to care for newly diagnosed PLWH.
