Preferences and uptake of home-based HIV self-testing for maternal retesting in Kenya.

OBJECTIVE: To compare preferences, uptake, and cofactors for unassisted home-based oral self-testing (HB-HIVST) versus clinic-based rapid diagnostic blood tests (CB-RDT) for maternal HIV retesting. DESIGN: Prospective cohort. METHODS: Between November 2017 and June 2019, HIV-negative pregnant Kenyan women receiving antenatal care were enrolled and given a choice to retest with HB-HIVST or CB-RDT. Women were asked to retest between 36 weeks gestation and 1-week post-delivery if the last HIV test was <24 weeks gestation or at 6 weeks postpartum if ≥24 weeks gestation, and self-report on retesting at a 14-week postpartum. RESULTS: Overall, 994 women enrolled and 33% (n = 330) selected HB-HIVST. HB-HIVST was selected because it was private (n = 224, 68%), convenient (n = 211, 63%), and offered flexibility in the timing of retesting (n = 207, 63%), whereas CB-RDT was selected due to the trust of providers to administer the test (n = 510, 77%) and convenience of clinic testing (n = 423, 64%). Among 905 women who reported retesting at follow-up, 135 (15%) used HB-HIVST. Most (n = 595, 94%) who selected CB-RDT retested with this strategy, compared to 39% (n = 120) who selected HB-HIVST retesting with HB-HIVST. HB-HIVST retesting was more common among women with higher household income and those who may have been unable to test during pregnancy (both retested postpartum and delivered <37 weeks gestation) and less common among women who were depressed. Most women said they would retest in the future using the test selected at enrollment (99% [n = 133] HB-HIVST; 93% [n = 715] CB-RDT-RDT). CONCLUSIONS: While most women preferred CB-RDT for maternal retesting, HB-HIVST was acceptable and feasible and could be used to expand HIV retesting options.

Acceptability, usability, and willingness to pay for HIV self-test kits distributed through community-based, PLHIV network-led and private practitioners models in India: Results from the STAR III Initiative.

INTRODUCTION: HIV self-testing (HIVST) has been shown to increase the uptake of HIV testing and help achieve the UNAIDS 95-95-95 targets. This study assessed the acceptability, usability (ease of use and result interpretation) and the willingness to pay for HIVST kits distributed through three distribution models, namely the community-based, PLHIV network-led and private practitioners models, in India. METHODS: This cross-sectional study was implemented across 14 states in India between September 2021 and June 2022. All participants could choose between blood-based or oral-fluid-based test kits. Participants were shown a test-kit usage demonstration video, and pre- and post-test counselling was provided for all. Participants were followed-up after testing, and if reported reactive, were further supported for linkage to confirmatory testing and antiretroviral therapy (ART) initiation. RESULTS: Among the 90,605 participants found eligible, 88,080 (97%) accepted an HIVST kit. Among the 87,976 who reported using an HIVST kit, 45,207 (51%) preferred a blood-based kit, and 42,120 (48%) reported testing for the first time. For future testing, 77,064 (88%) reported preferring HIVST over other HIV testing methods. Among those who used the kit, 83,308 (95%) found the kit easy to use, and 83,237 (95%) reported that the test results were easy to interpret. Among those who preferred HIVST for future use, 52,136 (69%) were willing to pay for the kit, with 35,854 (69%) of those willing to pay less than US$ 1.20. Only one instance of social harm was reported, with a participant reporting suicidal tendencies due to discord with their partner. Out of 328 participants (0.4%) who tested reactive with HIVST, 291 (89%) were linked to confirmatory testing; of these, 254 were confirmed HIV positive, and 216 (85%) successfully initiated ART. CONCLUSIONS: Overall, we report that nearly all participants were willing to accept HIVST, found the test kits easy to use and interpret, and about two-thirds were willing to pay for HIVST. Given the high levels of acceptance and the ability to reach a large proportion of first-time testers, HIVST in India could contribute to achieving the UNAIDS first 95 and ending the HIV epidemic.

Index Case HIV Testing Uptake and its Associated Factors at Oromia, Ethiopia.

BACKGROUND: Lack of index case testing increased the risk of contracting HIV among the families of index clients, partners, and biological children. The aim of this study was to determine the prevalence of index case HIV testing uptake and its associated factors at Oromia, Ethiopia. METHODS: An institutional-based cross-sectional study was conducted. A face-to-face interviewer administered structured questionnaire and chart review checklist were used to collect data. The data were analyzed using SPSS version 25. Logistic regressions were executed and statistical significance was declared at P < .05. RESULTS: The prevalence of index case testing was 80.2%. Factors associated with index case HIV testing uptake included HIV status disclosure (AOR = 5.4, 95% CI: 2.1, 14.0), discussed about HIV with family (AOR = 3.1, 95% CI: 1.2, 7.5), counseling of the index case (AOR = 3.3, 95% CI: 1.7, 10.6), perceived benefit of the index case tested (AOR = 3.2, 95% CI: 1.5, 8.7), being on ART 12 months or more (AOR = 2.6, 95% CI: 1.1, 6.1), and maintained privacy (AOR = 3.1, 95% CI: 1.3, 7.1). CONCLUSIONS: The uptake of index case HIV testing was moderately high. Additionally, factors such as HIV status disclosure, discussion of HIV with family, counseling of the index case, perception of the benefits of HIV testing for the index case, duration of clients on ART, and privacy maintenance during service delivery were significantly associated with index case HIV testing. To enhance index case testing, it is crucial to raise awareness and ensure client privacy during the initial HTC visit. Encouraging HIV status disclosure through discussion and promoting adherence to HIV medication is also recommended.

A typology of HIV self-testing support systems: a scoping review.

To maximise the benefits of HIV self-testing (HIVST), it is critical to support self-testers in the testing process and ensure that they access appropriate prevention and care. To summarise systems and tools supporting HIVST (hereafter, 'support systems') and categorise them for future analysis, we synthesised the global data on HIVST support systems and proposed a typology. We searched five databases for articles reporting on one or more HIVST support systems and included 314 publications from 224 studies. Across 189 studies, there were 539 reports of systems supporting HIVST use; while across 115 studies, there were 171 reports of systems supporting result interpretation. Most commonly, these were pictorial instructions, followed by in-person demonstrations and in-person assistance while self-testing or reading self-test results. Less commonly, virtual interventions were also identified, including online video conferencing and smartphone apps. Smartphone-based automated result readers have been used in the USA, China, and South Africa. Across 173 studies, there were 987 reports of systems supporting post-test linkage to care; most commonly, these were in-person referrals/counselling, written referrals, and phone helplines. In the USA, Bluetooth beacons have been trialled to monitor self-test use and facilitate follow-up. We found that, globally, HIVST support systems use a range of methods, including static media, virtual tools, and in-person engagement. In-person and printed approaches were more common than virtual tools. Other considerations, such as linguistic and cultural appropriateness, may also be important in the development of effective HIVST programs.

Barriers and facilitators to the implementation of rapid HIV testing in Canadian Emergency Departments: a mixed methods study.

OBJECTIVES: 1 in 7 Canadians with Human Immunodeficiency Virus (HIV) do not know their status. Patients at increased risk of HIV routinely access the emergency department (ED), yet few are tested, representing a missed opportunity for diagnosis and linkage-to-care. Rapid HIV testing provides reliable results within the same ED encounter but is not routinely implemented. The objective of this study was to identify barriers and facilitators to rapid HIV testing in Ontario EDs. METHODS: We employed a mixed-methods, convergent, parallel design study including online surveys and semi-structured interviews of physicians, nurses, and allied health across four hospitals in Toronto and Thunder Bay, Ontario. Data were analyzed in equal priority using descriptive statistics for quantitative data and thematic analysis for qualitative data guided by the Theoretical Domains framework and Capability, Opportunity, Motivation Behaviour change model. RESULTS: Among 187 survey respondents, 150 (80%) felt implementing rapid HIV testing would be helpful in the ED. Facilitators included availability of resources to link patients to care after testing (71%), testing early in patient encounters (41%), and having dedicated staff with lived experience support testing (34%). Motivation to offer testing included opportunities to support an underserved population (66%). Challenges to implementation included limited time during ED patient encounters (51%) and a lack of knowledge around HIV testing (42%) including stigma. Interview themes confirmed education, and integration of people with lived experience being essential to provide rapid HIV testing and linkage-to-care in the ED. CONCLUSIONS: Implementation of rapid HIV testing in the ED is perceived to be important irrespective of practice location or profession. Intrinsic motivations to support underserved populations and providing linkage-to-care are novel insights to facilitate testing in the ED. Streamlined implementation, including clear testing guidelines and improved access to follow-up care, is felt to be necessary for implementation.

ABSTRAIT: OBJECTIFS: 1 Canadien sur 7 atteint du virus de l'immunodéficience humaine (VIH) ne connaît pas son statut. Les patients présentant un risque accru de contracter le VIH ont régulièrement accès au service des urgences (SU), mais peu d'entre eux sont testés, ce qui représente une occasion manquée de diagnostic et de lien avec les soins. Le dépistage rapide du VIH fournit des résultats fiables dans la même situation d'urgence, mais n'est pas systématiquement mis en œuvre. L'objectif de cette étude était d'identifier les obstacles et les facilitateurs au dépistage rapide du VIH dans les urgences de l'Ontario. MéTHODES: Nous avons utilisé une étude de conception mixte, convergente et parallèle, y compris des sondages en ligne et des entrevues semi-structurées auprès de médecins, d'infirmières et d'auxiliaires de la santé dans quatre hôpitaux de Toronto et de Thunder Bay, en Ontario. Les données ont été analysées en priorité égale à l'aide de statistiques descriptives pour les données quantitatives et d'analyses thématiques pour les données qualitatives guidées par le cadre des domaines théoriques et le modèle de changement de capacité, d'opportunité et de motivation. RéSULTATS: Parmi 187 répondants au sondage, 150 (80 %) étaient d'avis que la mise en œuvre d'un dépistage rapide du VIH serait utile à l'urgence. Les facilitateurs comprenaient la disponibilité de ressources pour lier les patients aux soins après le test (71 %), le dépistage précoce lors des rencontres avec les patients (41 %) et la présence d'un personnel dévoué avec des tests de soutien de l'expérience vécue (34 %). La motivation à offrir des tests comprenait des occasions de soutenir une population mal desservie (66 %). Les difficultés de mise en œuvre comprenaient un temps limité pendant les rencontres avec les patients aux urgences (51 %) et un manque de connaissances sur le dépistage du VIH (42 %), y compris la stigmatisation. Les thèmes des entrevues ont confirmé que l'éducation et l'intégration des personnes ayant une expérience vécue sont essentielles pour fournir un dépistage rapide du VIH et un lien avec les soins aux urgences. CONCLUSIONS: La mise en œuvre du dépistage rapide du VIH aux urgences est perçue comme importante, quel que soit le lieu de pratique ou la profession. Les motivations intrinsèques à soutenir les populations mal desservies et à fournir un lien avec les soins sont de nouvelles idées pour faciliter les tests à l'urgence. Une mise en œuvre simplifiée, y compris des lignes directrices claires sur les tests et un meilleur accès aux soins de suivi, est jugée nécessaire pour la mise en œuvre.

Providing HIV-assisted partner services to partners of partners in western Kenya: an implementation science study.

INTRODUCTION: Assisted partner services (APS), or exposure notification and HIV testing for sexual partners of persons diagnosed HIV positive (index clients), is recommended by the World Health Organization. Most APS literature focuses on outcomes among index clients and their partners. There is little data on the benefits of providing APS to partners of partners diagnosed with HIV. METHODS: We utilized data from a large-scale APS implementation project across 31 facilities in western Kenya from 2018 to 2022. Females testing HIV positive at facilities were offered APS; those who consented provided contact information for all male sexual partners in the last 3 years. Male partners were notified of their potential HIV exposure and offered HIV testing services (HTS). Males newly testing positive were also offered APS and asked to provide contact information for their female partners in the last 3 years. Female partners of male partners (FPPs) were provided exposure notification and HTS. All participants with HIV were followed up at 12 months post-enrolment to assess linkage-to antiretroviral treatment (ART) and viral suppression. We compared HIV positivity, demographics and linkage outcomes among female index clients and FPPs. RESULTS: Overall, 5708 FPPs were elicited from male partners, of whom 4951 received HTS through APS (87% coverage); 291 FPPs newly tested HIV positive (6% yield), an additional 1743 (35.2%) reported a prior HIV diagnosis, of whom 99% were on ART at baseline. At 12 months follow-up, most FPPs were taking ART (92%) with very few adverse events: <1% reported intimate partner violence or reported relationship dissolution. FPPs were more likely than female index clients to report HIV risk behaviours including no condom use at last sex (45% vs. 30%) and multiple partners (38% vs. 19%). CONCLUSIONS: Providing HIV testing via APS to FPP is a safe and effective strategy to identify newly diagnosed females and achieve high linkage and retention to ART and can be an efficient means of identifying HIV cases in the era of declining HIV incidence. The high proportion of FPPs reporting HIV risk behaviours suggests APS may help interrupt community HIV transmission via increased knowledge of HIV status and linkage to treatment.

Effectiveness of HIV self-testing when offered within assisted partner services in Western Kenya (APS-HIVST Study): a cluster randomized controlled trial.

INTRODUCTION: Assisted partner services (APS) is an effective strategy for increasing HIV testing, new diagnosis, and linkage to care among sexual partners of people living with HIV (PLWH). APS can be resource intensive as it requires community tracing to locate each partner named and offer them testing. There is limited evidence for the effectiveness of offering HIV self-testing (HIVST) as an option for partner testing within APS. METHODS: We conducted a cluster randomized controlled trial comparing provider-delivered HIV testing (Standard APS) versus offering partners the option of provider-delivered testing or HIVST (APS+HIVST) at 24 health facilities in Western Kenya. Facilities were randomized 1:1 and we conducted intent-to-treat analyses using Poisson generalized linear mixed models to estimate intervention impact on HIV testing, new HIV diagnoses, and linkage to care. All models accounted for clustering at the clinic level and new diagnoses and linkage models were adjusted for individual-level age, sex, and income a priori. RESULTS: From March to December 2021, 755 index clients received APS and named 5054 unique partners. Among these, 1408 partners reporting a prior HIV diagnosis were not eligible for HIV testing and were excluded from analyses. Of the remaining 3646 partners, 96.9% were successfully contacted for APS and tested for HIV: 2111 (97.9%) of 2157 in the APS+HIVST arm and 1422 (95.5%) of 1489 in the Standard APS arm. In the APS+HIVST arm, 84.6% (1785/2111) tested via HIVST and 15.4% (326/2111) received provider-delivered testing. Overall, 16.7% of the 3533 who tested were newly diagnosed with HIV (APS+HIVST = 357/2111 [16.9%]; Standard APS = 232/1422 [16.3%]). Of the 589 partners who were newly diagnosed, 90.7% were linked to care (APS+HIVST = 309/357 [86.6%]; Standard APS = 225/232 [97.0%]). There were no significant differences between the two arms in HIV testing (relative risk [RR]: 1.02, 95% CI: 0.96-1.10), new HIV diagnoses (adjusted RR [aRR]: 1.03, 95% CI: 0.76-1.39) or linkage to care (aRR: 0.88, 95% CI: 0.74-1.06). CONCLUSIONS: There were no differences between APS+HIVST and Standard APS, demonstrating that integrating HIVST into APS continues to be an effective strategy for identifying PLWH by successfully reaching and HIV testing >95% of elicited partners, newly diagnosing with HIV one in six of those tested, >90% of whom were linked to care. CLINICAL TRIAL NUMBER: NCT04774835.

Estimating the potential value of MSM-focused evidence-based implementation interventions in three Ending the HIV Epidemic jurisdictions in the United States: a model-based analysis.

INTRODUCTION: Improving the delivery of existing evidence-based interventions to prevent and diagnose HIV is key to Ending the HIV Epidemic in the United States. Structural barriers in the access and delivery of related health services require municipal or state-level policy changes; however, suboptimal implementation can be addressed directly through interventions designed to improve the reach, effectiveness, adoption or maintenance of available interventions. Our objective was to estimate the cost-effectiveness and potential epidemiological impact of six real-world implementation interventions designed to address these barriers and increase the scale of delivery of interventions for HIV testing and pre-exposure prophylaxis (PrEP) in three US metropolitan areas. METHODS: We used a dynamic HIV transmission model calibrated to replicate HIV microepidemics in Atlanta, Los Angeles (LA) and Miami. We identified six implementation interventions designed to improve HIV testing uptake ("Academic detailing for HIV testing," "CyBER/testing," "All About Me") and PrEP uptake/persistence ("Project SLIP," "PrEPmate," "PrEP patient navigation"). Our comparator scenario reflected a scale-up of interventions with no additional efforts to mitigate implementation and structural barriers. We accounted for potential heterogeneity in population-level effectiveness across jurisdictions. We sustained implementation interventions over a 10-year period and evaluated HIV acquisitions averted, costs, quality-adjusted life years and incremental cost-effectiveness ratios over a 20-year time horizon (2023-2042). RESULTS: Across jurisdictions, implementation interventions to improve the scale of HIV testing were most cost-effective in Atlanta and LA (CyBER/testing cost-saving and All About Me cost-effective), while interventions for PrEP were most cost-effective in Miami (two of three were cost-saving). We estimated that the most impactful HIV testing intervention, CyBER/testing, was projected to avert 111 (95% credible interval: 110-111), 230 (228-233) and 101 (101-103) acquisitions over 20 years in Atlanta, LA and Miami, respectively. The most impactful implementation intervention to improve PrEP engagement, PrEPmate, averted an estimated 936 (929-943), 860 (853-867) and 2152 (2127-2178) acquisitions over 20 years, in Atlanta, LA and Miami, respectively. CONCLUSIONS: Our results highlight the potential impact of interventions to enhance the implementation of existing evidence-based interventions for the prevention and diagnosis of HIV.

Advancing Programme Science approaches to understand gaps in HIV prevention programme coverage for key populations in 12 Nigerian states: findings from the 2020 Integrated Biological and Behavioural Surveillance Survey.

INTRODUCTION: Effective HIV prevention programme coverage is necessary to achieve Nigeria's goal of ending the epidemic by 2030. Recent evidence highlights gaps in service coverage and utilization across the country. The Effective Programme Coverage framework is a Programme Science tool to optimize a programme's population-level impact by examining gaps in programme coverage using data generated through programme-embedded research and learning. We apply the framework using Integrated Biological and Behavioural Surveillance Survey (IBBSS) data from Nigeria to examine coverage of four prevention interventions-condoms, HIV testing, and needle and syringe programmes (NSP)-among four key population groups-female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID) and transgender people. METHODS: Data from Nigeria's 2020 IBBSS, implemented in 12 states, were analysed to examine HIV prevention programme coverage among key populations. For each key population group and prevention intervention of interest, weighted IBBSS data were used to retrospectively generate coverage cascades that identify and quantify coverage gaps. Required coverage targets were informed by targets articulated in Nigeria's National HIV/AIDS Strategic Framework or, in their absence, by guidelines from policy normative bodies. Availability-, outreach- and utilization coverage proxy indicators were defined using variables from IBBSS data collection tools. Sankey diagrams are presented to visualize pathways followed by participants between coverage cascade steps. RESULTS: Required coverage targets were missed for HIV testing and NSP among all key population groups. Condom availability coverage surpassed required coverage targets among FSW and MSM, while utilization coverage only among FSW exceeded the 90% required coverage target. Outreach coverage was low for all key population groups, falling below all required coverage targets. CONCLUSIONS: Our findings identify critical gaps in HIV prevention programme coverage for key populations in Nigeria and demonstrate non-linear movement across coverage cascades, signalling the need for innovative solutions to optimize coverage of prevention services. Programme-embedded research is required to better understand how key population groups in Nigeria access and use different HIV prevention services so that programmes, policies and resource allocation decisions can be optimized to achieve effective programme coverage and population-level impact.

A citizen science approach to develop a digital intervention to reduce HIV stigma and promote HIV self-testing among adolescents and young adults: a mixed methods analysis from Kazakhstan.

INTRODUCTION: Kazakhstan has one of the fastest-growing HIV epidemics in the world, with increasing rates among adolescents and young adults (AYA). Innovative strategies are needed to increase HIV testing uptake and decrease HIV stigma among AYA. Citizen science, defined as the active engagement of the general public in scientific research tasks, promotes and facilitates community engagement throughout the research process. This citizen science study used crowdsourcing to engage AYA in Kazakhstan to develop a digital intervention to reduce HIV stigma and promote HIV self-testing. Our objectives in this paper are to describe the approach used, its feasibility and acceptability, and AYA motivations for and lessons learned collaborating on the study. METHODS: From October 2021 to July 2022, in collaboration with a Community Collaborative Research Board and a Youth Advisory Board, we developed an open call requesting multimedia submissions to reduce HIV testing stigma. Eligible submissions were separated by age group (13-19 or 20-29 years) and judged by a panel composed of AYA (n = 23), healthcare professionals (n = 12), and representatives from the local government and non-governmental organizations (n = 17). Each entry was reviewed by at least four judges and ranked on a 5-point scale. The top 20 open call contestants were asked to submit self-recordings sharing their motivation for and experience participating in the contest and lessons learned. Descriptive statistics were calculated for quantitative data. Qualitative data were coded using open coding. RESULTS: We received 96 submissions from 77 youth across Kazakhstan. Roughly, three-quarters (n = 75/96) of entries met judging eligibility criteria. Of the eligible entries, over half (n = 39/75) scored 3.5 or higher on a 5-point scale (70.0%). The most frequent types of entries were video (n = 36/96, 37.5%), image (n = 28/96, 29.2%) and text (n = 24/96, 25.0%). AYA's primary motivations for collaborating on the study included a desire to improve society and help youth. The main challenges included creating content to address complex information using simple language, finding reliable information online and technological limitations. CONCLUSIONS: Crowdsourcing was feasible and highly acceptable among AYA in Kazakhstan. Citizen science approaches hold great promise for addressing the increasingly complex health and social challenges facing communities today.

The effects of regular home delivery of HIV self-testing and follow-up counselling on HIV testing and prevention outcomes in men who have sex with men who test infrequently in the United States: a pragmatic, virtual randomized controlled trial.

INTRODUCTION: Past research shows that HIV self-testing (HIVST) can increase testing and facilitate more HIV diagnoses relative to clinic testing. However, in the United States, the use of HIVSTs is limited due to concerns that those who use HIVST could be less likely to be linked to care. METHODS: From January 2019 to April 2022, we recruited 811 men who have sex with men (MSM) in the United States who tested infrequently using an online marketing campaign and randomized them 1:1:1 to receive one of the following every 3 months for a year: (1) text message reminders to get tested at a local clinic (control); (2) mailed HIVST kits with access to a free helpline (standard HIVST); and (3) mailed HIVST kits with counselling provided within 24 hours of opening a kit (eTest). Quarterly follow-up surveys assessed HIV testing, sexually transmitted infection (STI) testing, pre-exposure prophylaxis (PrEP) use and sexual risk behaviour. FINDINGS: Eight participants were diagnosed with HIV, and all but one were through HIVST. Participants in either HIVST condition, standard or eTest, had significantly higher odds of any testing (OR = 7.9, 95% CI = 4.9-12.9 and OR = 6.6, 95% CI = 4.2-10.5) and repeat testing (>1 test; OR = 8.5, 95% CI = 5.7-12.6; OR = 8.9, 95% CI = 6.1-13.4) over 12 months relative to the control group. Rates of STI testing and PrEP uptake did not differ across study condition, but those in the eTest condition reported 27% fewer sexual risk events across the study period relative to other groups. CONCLUSIONS: HIVST vastly increased testing, encouraged more regular testing among MSM, and identified nearly all new cases, suggesting that HIVST could diagnose HIV acquisition earlier. Providing timely follow-up counselling after HIVST did not increase rates of STI testing or PrEP use, but some evidence suggested that counselling may have reduced sexual risk behaviour. To encourage more optimal testing, programmes should incorporate HIVST and ship kits directly to recipients at regular intervals.

Effectiveness of Using Additional HIV Self-Test Kits as an Incentive to Increase HIV Testing Within Assisted Partner Services.

BACKGROUND: Incentives have shown mixed results in increasing HIV testing rates in low-resource settings. We investigated the effectiveness of offering additional self-tests (HIVSTs) as an incentive to increase testing among partners receiving assisted partner services (APS). SETTING: Western Kenya. METHODS: We conducted a single-crossover study nested within a cluster-randomized controlled trial. Twenty-four facilities were randomized 1:1 to (1) control: provider-delivered testing or (2) intervention: offered 1 HIVST or provider-delivered testing for 6 months (pre-implementation), then switched to offering 2 HIVSTs for 6 months (post-implementation). A difference-in-differences approach using generalized linear mixed models, accounting for facility clustering and adjusting for age, sex, and income, was used to estimate the effect of the incentive on HIV testing and first-time testing among partners in APS. RESULTS: March 2021-June 2022, 1127 index clients received APS and named 8155 partners, among whom 2333 reported a prior HIV diagnosis and were excluded from analyses, resulting in 5822 remaining partners: 3646 (62.6%) and 2176 (37.4%) in the pre-implementation and post-implementation periods, respectively. Overall, 944/2176 partners (43%) were offered a second HIVST during post-preimplementation, of whom 34.3% picked up 2 kits, of whom 71.7% reported that the second kit encouraged HIV testing. Comparing partners offered 1 vs. two HIVSTs showed no difference in HIV testing (relative risk: 1.01, 95% confidence interval: 0.951 to 1.07) or HIV testing for the first time (relative risk: 1.23, 95% confidence interval: 0.671 to 2.24). CONCLUSIONS: Offering a second HIVST as an incentive within APS did not significantly impact HIV testing or first-time testing, although those opting for 2 kits reported it incentivized them to test.

Reaching for 90:90:90 in Correctional Facilities in South Africa and Zambia: Virtual Cross-Section of Coverage of HIV Testing and Antiretroviral Therapy During Universal Test and Treat Implementation.

BACKGROUND: People in correctional settings are a key population for HIV epidemic control. We sought to demonstrate scale-up of universal test and treat in correctional facilities in South Africa and Zambia through a virtual cross-sectional analysis. METHODS: We used routine data on 2 dates: At the start of universal test and treat implementation (time 1, T1) and 1 year later (time 2, T2). We obtained correctional facility census lists for the selected dates and matched HIV testing and treatment data to generate virtual cross-sections of HIV care continuum indicators. RESULTS: In the South African site, there were 4193 and 3868 people in the facility at times T1 and T2; 43% and 36% were matched with HIV testing or treatment data, respectively. At T1 and T2, respectively, 1803 (43%) and 1386 (36%) had known HIV status, 804 (19%) and 845 (21%) were known to be living with HIV, and 60% and 56% of those with known HIV were receiving antiretroviral therapy (ART). In the Zambian site, there were 1467 and 1366 people in the facility at times T1 and T2; 58% and 92% were matched with HIV testing or treatment data, respectively. At T1 and T2, respectively, 857 (59%) and 1263 (92%) had known HIV status, 277 (19%) and 647 (47%) were known to be living with HIV, and 68% and 68% of those with known HIV were receiving ART. CONCLUSIONS: This virtual cross-sectional analysis identified gaps in HIV testing coverage, and ART initiation that was not clearly demonstrated by prior cohort-based studies.

Social network strategies to distribute HIV self-testing kits: a global systematic review and network meta-analysis.

INTRODUCTION: Social network strategies, in which social networks are utilized to influence individuals or communities, are increasingly being used to deliver human immunodeficiency virus (HIV) interventions to key populations. We summarized and critically assessed existing research on the effectiveness of social network strategies in promoting HIV self-testing (HIVST). METHODS: Using search terms related to social network interventions and HIVST, we searched five databases for trials published between 1st January 2010 and 30th June 2023. Outcomes included uptake of HIV testing, HIV prevalence and linkage to antiretroviral therapy (ART) or HIV care. We used network meta-analysis to assess the uptake of HIV testing through social network strategies compared with control methods. A pairwise meta-analysis of studies with a comparison arm that reported outcomes was performed to assess relative risks (RR) and their corresponding 95% confidence intervals (CI). RESULTS: Among the 4496 manuscripts identified, 39 studies fulfilled the inclusion criteria, including one quasi-experimental study, 22 randomized controlled trials and 16 observational studies. Networks HIVST testing was organized by peers (distributed to known peers, 15 studies), partners (distributed to their sexual partners, 16 studies) and peer educators (distributed to unknown peers, 8 studies). Among social networks, simulating the possibilities of ranking position, peer distribution had the highest uptake of HIV testing (84% probability), followed by partner distribution (80% probability) and peer educator distribution (74% probability). Pairwise meta-analysis showed that peer distribution (RR 2.29, 95% CI 1.54-3.39, 5 studies) and partner distribution (RR 1.76, 95% CI 1.50-2.07, 10 studies) also increased the probability of detecting HIV reactivity during testing within the key population when compared to the control. DISCUSSION: All of the three social network distribution strategies enhanced the uptake of HIV testing compared to standard facility-based testing. Linkage to ART or HIV care remained comparable to facility-based testing across the three HIVST distribution strategies. CONCLUSIONS: Network-based HIVST distribution is considered effective in augmenting HIV testing rates and reaching marginalized populations compared to facility-based testing. These strategies can be integrated with the existing HIV care services, to fill the testing gap among key populations globally. PROSPERO NUMBER: CRD42022361782.

Effectiveness of integrating HIV prevention within sexual reproductive health services with or without peer support among adolescents and young adults in rural KwaZulu-Natal, South Africa (Isisekelo Sempilo): 2 × 2 factorial, open-label, randomised controlled trial.

BACKGROUND: Approximately 200 000 South Africans acquired HIV in 2021 despite the availability of universal HIV test and treat and pre-exposure prophylaxis (PrEP). The aim of this study was to test the effectiveness of sexual and reproductive health services or peer support, or both, on the uptake of serostatus neutral HIV services or reduction of sexually transmissible HIV. METHODS: We did an open-label, 2 × 2 randomised factorial trial among young people in a mostly rural area of KwaZulu-Natal, South Africa. Inclusion criteria included being aged 16-29 years, living in the mapped geographical areas that were accessible to the area-based peer navigators, being willing and able to provide informed consent, and being willing to provide a dried blood spot for anonymous HIV testing and HIV viral load measurement at 12 months. Participants were randomly allocated by computer-generated algorithm to one of four groups: those in the standard-of-care group were referred to youth-friendly services for differentiated HIV prevention (condoms, universal HIV test and treat with antiretroviral therapy, and PrEP if eligible); those in the sexual and reproductive health services group received baseline self-collected specimens for sexually transmitted infection (STI) testing and referral to integrated sexual and reproductive health and HIV prevention services; those in the peer support group were referred to peer navigators for health promotion, condom provision, and facilitation of attendance for differentiated HIV prevention services; and those in the final group received a combination of sexual and reproductive health services and peer support. Coprimary outcomes were linkage to clinical services within 60 days of enrolment, proportion of participants who had sexually transmissible HIV at 12 months after enrolment, and proportion of sampled individuals who consented to participation and gave a dried blood spot for HIV testing at 12 months. Logistic regression was used for analyses, and adjusted for age, sex, and rural or peri-urban area of residence. This study is registered with ClinicalTrials.gov (NCT04532307) and is closed. FINDINGS: Between March 2, 2020, and July 7, 2022, 1743 (75·7%) of 2301 eligible individuals were enrolled and followed up. 12-month dried blood spots were collected from 1168 participants (67·0%). The median age of the participants was 21 years (IQR 18-25), 51·4% were female, and 51·1% had secondary level education. Baseline characteristics and 12-month outcome ascertainment were similar between groups. 755 (43·3%) linked to services by 60 days. 430 (49·8%) of 863 who were in the sexual reproductive health services group were linked to care compared with 325 (36·9%) of 880 who were not in the sexual and reproductive health services group (adjusted odds ratio [aOR] 1·68; 95% CI 1·39-2·04); peer support had no effect: 385 (43·5%) of 858 compared with 370 (43·1%) of 885 (1·02, 0·84-1·23). At 12 months, 227 (19%) tested ELISA-positive for HIV, of whom 41 (18%) had viral loads of 400 copies per mL; overall prevalence of transmissible HIV was 3·5%. 22 (3·7%) of 578 participants in the sexual and reproductive health services group had transmissible HIV compared with 19 (3·3%) of 590 not in the sexual and reproductive health services group (aOR 1·12; 95% CI 0·60-2·11). The findings were also non-significant for peer support: 21 (3·3%) of 565 compared with 20 (3·3%) of 603 (aOR 1·03; 95% CI 0·55-1·94). There were no serious adverse events or deaths during the study. INTERPRETATION: This study provides evidence that STI testing and sexual and reproductive health services create demand for serostatus neutral HIV prevention in adolescents and young adults in Africa. STI testing and integration of HIV and sexual health has the potential to reach those at risk and tackle unmet sexual health needs.

Qualitative evaluation of digital vending machines to improve access to STI and HIV testing in South West England: using a Person-Based Approach.

OBJECTIVES: To report the development, implementation, acceptability and feasibility of vending machines offering HIV and sexually transmitted infection (STI) testing kits. DESIGN: A qualitative study using the Person-Based Approach with patient and public involvement workshops and stakeholder involvement and interviews with machine users, sexual health service (SHS) staff, venue staff and local authority sexual health commissioners. Transcripts were analysed thematically. SETTING: Bristol, North Somerset and South Gloucestershire (BNSSG). PARTICIPANTS: 15 machine users, 5 SHS staff, 3 venue staff and 3 local authority commissioners. INTERVENTION: Four vending machines dispensing free HIV self-testing and STI self-sampling kits in publicly accessible venues across BNSSG were introduced to increase access to testing for groups at higher risk of HIV and STI infection who are less likely to access SHS clinic testing services (young people, people from black communities, and gay, bisexual and other men who have sex with men). RESULTS: Machine users reported the service was convenient, easy to use and accessible; however, concerns regarding privacy related to machine placement within the venues and issues of maintenance were raised. Promotional material was inclusive and informative; however, awareness of the service through the promotional campaign was limited. Vending machines were acceptable to venue staff once clear processes for their management were agreed with the SHS. SHS staff identified challenges with the implementation of the service related to the limited involvement of the whole SHS team in the planning and development. CONCLUSIONS: The codeveloped vending machine service was acceptable, addressing some barriers to testing. Resources and protected staff time are needed to support greater involvement of the whole SHS team and service providers in venues. Adopting a similarly robust coproduction approach to the implementation of the machines could avoid the challenges reported. The placement of the machines to assure users privacy and repeated, targeted promotion could encourage service use among target groups.

HIV self-testing in India: implementation and qualitative evaluation of a web-based programme with virtual counsellor support.

INTRODUCTION: To achieve epidemic control of infectious diseases, engaging higher-burden populations with accessible diagnostic services is critical. HIV self-testing (HIVST) is a promising option. METHODS: We implemented an online HIVST programme for key populations across India. Eligible clients were 18 years or older, self-reported a negative or unknown HIV status and reported not taking antiretroviral therapy. Clients who reported a prior HIV diagnosis were not eligible to receive an HIVST kit. HIVST clients received kits via courier or in person at pre-determined pick-up points supported by trained counselling staff. Virtual counsellors engaged clients online and by phone and offered support to register, access, and complete HIVST free of cost. Virtual counsellors supported clients to report results and engage with follow-up services. Follow-up included linking clients with a positive result to confirmatory testing and HIV care services. We assessed programmatic data across HIV continuum outcomes and conducted a qualitative evaluation through interviews with purposively sampled clients. RESULTS: Between 30 June 2021 and 30 September 2022, 5324 clients ordered an HIVST kit (76% men, 13% women, 7% transgender people, 4% unknown gender). Of the 4282 clients reporting results (94% of those who received a kit), 6% screened positive, among whom 72% (n = 184) completed confirmatory testing. Themes from 41 client interviews included satisfaction about the convenience and privacy of services and the discreet nature of kit delivery. Respondents were drawn to the convenience of HIVST and appreciated gaining courage and comfort throughout the process from virtual counsellor support. For respondents who screened positive, challenges to care linkage included fearing judgemental questions from public providers and wanting more time before starting treatment. Clients shared concerns about kit accuracy and suggested that instructional materials be provided with more diverse language options. CONCLUSIONS: Web-based HIVST services with tailored support appeared to facilitate HIV service access and engagement of harder-to-reach populations across India. Assistance from a community-oriented counsellor proved important to overcome literacy barriers and mistrust  in order to support the HIVST process and service linkage. Learnings can inform global efforts to improve the critical step of diagnosis in achieving epidemic control for HIV and other infectious diseases.

Results of the Sukuma Ndoda ("Stand up, Man") HIV Self-Screening and Assisted Linkage to Care Project in Johannesburg: A Quasi-Experimental Pre-Post Evaluation.

BACKGROUND: HIV testing rates among South African men lag behind rates for women and national targets. Community-based HIV self-screening (HIVSS) distribution and follow-up by community health workers (CHWs) is a scalable option to increase testing coverage, diagnosis, and treatment initiation. We provided HIVSS and assisted linkage to care to men not recently tested (within the past 12 months) residing in high-HIV-burden areas of Johannesburg. METHODS: CHWs distributed HIVSS in 6 clinic catchment areas. Follow-up to encourage confirmatory testing and antiretroviral therapy initiation was conducted through personal support (PS) or an automated short message service (SMS) follow-up and linkage system in 3 clinic areas each. Using a quasi-experimental pre-post design, we compared differences in the proportion of men testing in the clinic catchment areas during the HIVSS campaign (June-August 2019) to the 3 months prior (March-May 2019) and compared treatment initiations by assisted linkage strategy. RESULTS: Among 4793 participants accepting HIVSS, 62% had never tested. Among 3993 participants with follow-up data, 90.6% reported using their HIVSS kit. Testing coverage among men increased by 156%, from under 4% when only clinic-based HIV testing services were available to 9.5% when HIVSS and HIV testing services were available (z = -11.6; P < 0.01). Reported test use was higher for men followed through PS (99% vs. 68% in SMS); however, significantly more men reported reactive self-test results in the SMS group compared with PS (6.4% vs. 2.0%), resulting in more antiretroviral therapy initiations in the SMS group compared with PS (23 vs. 9; P < 0.01). CONCLUSIONS: CHW HIVSS distribution significantly increases testing among men. While PS enabled personalized follow-up, reporting differences indicate SMS is more acceptable and better aligned with expectations of privacy associated with HIVSS.
