In-home TB Testing Using GeneXpert Edge is Acceptable, Feasible, and Improves the Proportion of Symptomatic Household Contacts Tested for TB: A Proof-of-Concept Study.

Background: Household contact investigations are effective for finding tuberculosis (TB) cases but are hindered by low referral uptake for clinic-based evaluation and testing. We assessed the acceptability and feasibility of in-home testing of household contacts (HHC) using the GeneXpert Edge platform. Methods: We conducted a 2-arm, randomized study in Eastern Cape, South Africa. HHCs were verbally assessed using the World Health Organization-recommended 4-symptom screen. Households with ≥1 eligible symptomatic contact were randomized. Intervention households received in-home GeneXpert MTB/RIF molecular testing. GeneXpert-positive HHCs were referred for clinic-based treatment. Standard-of-care households were referred for clinic-based sputum collection and testing. We defined acceptability as agreeing to in-home testing and feasibility as generation of valid Xpert MTB/RIF results. The proportion and timeliness of test results received was compared between groups. Results: Eighty-four households were randomized (n = 42 per arm). Of 100 eligible HHCs identified, 98/100 (98%) provided consent. Of 51 HHCs allocated to the intervention arm, all accepted in-home testing; of those, 24/51 (47%) were sputum productive and 23/24 (96%) received their test results. Of 47 HCCs allocated to standard-of-care, 7 (15%) presented for clinic-based TB evaluation, 6/47 (13%) were tested, and 4/6 (67%) returned for their results. The median (interquartile range) number of days from screening to receiving test results was 0 (0) and 16.5 (11-15) in the intervention and standard-of-care arms, respectively. Conclusions: In-home testing for TB was acceptable, feasible, and increased HHCs with a molecular test result. In-home testing mitigates a major limitation of household contact investigations (dependency on clinic-based referral), revealing new strategies for enhancing early case detection.

"I know why I am taking this pill": Young women navigation of disclosure and support for PrEP uptake and adherence in Eastern Cape Province, South Africa.

There is limited understanding of the dynamic interplay between adolescent girl's and young women's (AGYW) disclosure and social support for using oral pre-exposure prophylaxis (PrEP) and adherence. Towards this, we conducted interviews with 42 AGYW enrolled in The Community PrEP Study who exhibited either high or low blood concentrations of tenofovir-diphosphate (TFV-DP) in dried blood spots. Guided by Theories of Practice, interviews and analysis focused on AGYW perspectives and experiences with PrEP disclosure, support and adherence. AGYW with high TFV-DP blood concentrations described larger social support networks and disclosure events. In contrast, those with low TFV-DP blood concentrations described disclosing to fewer people, resulting in limited social support. Participants discussed partner support, however, this support was not described as consequential to adherence, irrespective of TFV-DP levels. Those with high levels of TFV-DP in their blood described the ability to navigate social scrutiny and changes in social support, while those with low levels of TFV-DP in their blood were more likely to question their own continued use of PrEP. To facilitate AGYW's prevention-effective use of PrEP, expanded skill-building for disclosure and resiliency against changes to social support should be examined as part of PrEP services.

Qualitative Identification of Intervention Preferences to Support Men's Engagement and Retention in TB Care in South Africa.

Globally and in South African specifically, men account for 56% and 62% of all tuberculosis (TB) cases, respectively. Men are at increased risk of not accessing TB testing or treatment, and having poor treatment outcomes. Unfortunately, no interventions exist to address these issues. Toward the development of targeted, patient-centered TB care and support interventions, we used semistructured interviews to explored men's social network composition, TB testing behaviors, disclosure and treatment support, clinical experiences, and TB's influence on daily living. Data were analyzed using a thematic approach guided by the Network Individual Resource Model to identify mental and tangible resources influential and preferred during engagement in TB treatment. Men emphasized the desire for peer-to-peer support to navigate TB-related stigma and unhealthy masculinity norms. Men advocated for awareness events to educate communities about their challenges with TB. Men strongly suggested that interventions be delivered in familiar locations where men congregate. Since 2022, no TB treatment support interventions have included the preferred components or delivery modes described by men in our study. To improve men's TB-related health outcomes, the global TB community must identify and address men's unique challenges when designing interventions.

Acceptability and feasibility of leveraging community-based HIV counselling and testing platforms for same-day oral PrEP initiation among adolescent girls and young women in Eastern Cape, South Africa.

INTRODUCTION: Community-based delivery of HIV pre-exposure prophylaxis (PrEP) to South African adolescent girls and young women's (AGYW) could increase access but needs evaluation. We integrated PrEP services via home-based services and pop-up tents into existing community-based HIV testing services (CB-HTS) in Eastern Cape Province, South Africa. METHODS: After accessing CB-HTS via a "pop-up" tent or home-based services, HIV-negative AGYW aged 16-25 years were invited to complete a baseline questionnaire and referred for PrEP services at a community-based PrEP site co-located with pop-up HTS tents. A 30-day supply of PrEP was dispensed. PrEP uptake, time-to-initiation, cohort characteristics and first medication refill within 90 days were measured using descriptive statistics. RESULTS: Of the 1164 AGYW who tested for HIV, 825 (74.3%) completed a questionnaire and 806 (97.7%) were referred for community-based PrEP. Of those, 624 (77.4%) presented for PrEP (482/483 [99.8%] from pop-up HTS and 142/323 [44.0%] from home-based HTS), of which 603 (96.6%) initiated PrEP. Of those initiating PrEP following home-based HTS, 59.1% initiated within 0-3 days, 25.6% within 4-14 days and 15.3% took ≥15 days to initiate; 100% of AGYW who used pop-up HTS initiated PrEP the same day. Among AGWY initiating PrEP, 37.5% had a detectable sexually transmitted infection (STI). Although AGYW reported a low self-perception of HIV risk, post-hoc application of HIV risk assessment measures to available data classified most study participants as high risk for HIV acquisition. Cumulatively, 329 (54.6%) AGYW presented for a first medication refill within 90 days of accepting their first bottle of PrEP. CONCLUSIONS: Leveraging CB-HTS platforms to provide same-day PrEP initiation and refill services was acceptable to AGYW. A higher proportion of AGYW initiated PrEP when co-located with CB-HTS sites compared to those referred following home-based HTS, suggesting that proximity of CB-HTS and PrEP services facilitates PrEP uptake among AGYW. The high prevalence of STIs among those initiating PrEP necessitates the integration of STI and HIV prevention programs for AGYW. Eligibility for PrEP initiation should not be required among AHYW in high HIV burden communities. Community-based service delivery will be crucial to maintaining access to PrEP services during the COVID-19 pandemic and future health and humanitarian emergencies.

Improving Healthcare Worker Resilience and Well-Being During COVID-19 Using a Self-Directed E-Learning Intervention.

Introduction: High rates of burnout, depression, anxiety, and insomnia in healthcare workers responding to the COVID-19 pandemic have been reported globally. Methods: Responding to the crisis, the Foundation for Professional Development (FPD) developed an e-learning course to support healthcare worker well-being and resilience. A self-paced, asynchronous learning model was used as the training intervention. Each module included practical, skill-building activities. An outcome evaluation was conducted to determine if completing the course improved healthcare worker knowledge of and confidence in the learning outcomes of the course, their use of resilience-building behaviours, their resilience, and their well-being. A secondary objective was to explore if there were any associations between behaviours, resilience, and well-being. Participants completed pre- and post-course questionnaires to measure knowledge of and confidence in the learning outcomes, y, frequency of self-reported resilience-building behaviours, and levels of resilience (CD-RISC) and well-being (WHO-5). Results were analysed in STATA using paired T-tests, univariate and multivariate linear regression models. Results: Participants (n = 474; 77.6% female; 55.7% primary care) exhibited significant increases in knowledge, confidence, resilience-building behaviour, resilience, and well-being scores. Statistically significant improvements in the frequency of resilience-building behaviours led to significant improvements in resilience (0.25 points; 95% CI: 0.06, 0.43) and well-being (0.21 points; 95% CI: 0.05, 0.36). Increasing changes in well-being scores had a positive effect on change in resilience scores (ß = 0.20; 95% CI: 0.11, 0.29), and vice versa (ß = 0.28; 95% CI: 0.14, 0.41). Conclusion: A healthcare worker e-learning course can build knowledge and skills that may prompt changes in resilience-building behaviours and improvements in well-being and resilience scores. The findings suggest that e-learning courses may improve more than competency-based outcomes alone but further research is warranted to further explore these relationships.

The Community PrEP Study: a randomized control trial leveraging community-based platforms to improve access and adherence to pre-exposure prophylaxis to prevent HIV among adolescent girls and young women in South Africa-study protocol.

BACKGROUND: HIV incidence among South African adolescent girls and young women (AGYW) remains high, but could be reduced by highly effective pre-exposure prophylaxis (PrEP). Unfortunately, AGYW report significant barriers to clinic-based sexual and reproductive health services. Even when AGYW access PrEP as an HIV prevention method, poor prevention-effective use was a serious barrier to achieving its optimal HIV prevention benefits. Determining the acceptability and feasibility of community-based platforms to increase AGYW's access to PrEP, and evaluating behavioural interventions to improve prevention-effective use of PrEP are needed. METHODS: We propose a mixed-methods study among AGYW aged 16-25 years in Eastern Cape Province, South Africa. In the first component, a cross-sectional study will assess the acceptability and feasibility of leveraging community-based HIV counselling and testing (CBCT) platforms to refer HIV-negative, at-risk AGYW to non-clinic-based, same-day PrEP initiation services. In the second component, we will enrol 480 AGYW initiating PrEP via our CBCT platforms into a three-armed (1:1:1) randomized control trial (RCT) that will evaluate the effectiveness of adherence support interventions to improve the prevention-effective use of PrEP. Adherence will be measured over 24 months via tenofovir-diphosphate blood concentration levels. Qualitative investigations will explore participant, staff, and community experiences associated with community-based PrEP services, adherence support activities, study implementation, and community awareness. Costs and scalability of service platforms and interventions will be evaluated. DISCUSSION: This will be the first study to assess the acceptability and feasibility of leveraging CBCT platforms to identify and refer at-risk AGYW to community-based, same-day PrEP initiation services. It will also provide quantitative and qualitative results to inform adherence support activities and services that promote the prevention-effective use of PrEP among AGYW. By applying principles of implementation science, behavioural science, and health economics research, we aim to inform strategies to improve access to and prevention-effective use of PrEP by AGYW.

Outcomes from a multimodal, at-scale community-based HIV counselling and testing programme in twelve high HIV burden districts in South Africa.

INTRODUCTION: Facility-based HIV testing services (HTS) have been less acceptable and accessible by adolescents, men and key populations in South Africa. Community-based HIV counselling and testing (CBCT) modalities, including mobile unit and home-based testing, have been proposed to decrease barriers to HIV testing uptake. CBCT modalities and approaches may be differentially acceptable to men and women based on age. Implementation of multimodal CBCT services may improve HIV testing rates among adolescents and men, and support the roll-out of prevention services. METHODS: A cross-sectional analysis was conducted using aggregate, routine programmatic data collected from 1 October 2015 through 31 March 2017 from a multimodal, at-scale CBCT programme implemented in 12 high-burden districts throughout South Africa. Data collection tools were aligned to reporting standards for the National Department of Health and donor requirements. HIV testing rates (i.e. number of tests performed per 100,000 population using South African census data) and testing proportions by modality were stratified by sex, age groups and heath districts. Descriptive statistics were performed using STATA 13.0. RESULTS: Overall, 944,487 tests were performed during the 1.5-year testing period reported. More tests were conducted among females than males (53.6% vs. 46.4%). Overall, 8206 tests per 100,000 population (95% CI: 8190.2 to 8221.9) were performed; female-to-male (F:M) testing ratio was 1.11. Testing rates were highest among young women age 20 to 24 years (16,328.4; 95% CI: 16,237.9 to 16,419.1) and adolescent girls aged 15 to 19 years (12,817.0; 95% CI: 12,727.9 to 12,906.6). Home-based testing accounted for 61.3% of HIV tests, followed by near-home mobile unit testing (30.2%) and workplace mobile unit testing (4.7%). More women received HTS via home-based testing (F:M ratio = 1.29), whereas more men accessed work-place mobile testing (M:F ratio = 1.35). No sex differential was observed among those accessing near-home mobile testing (F:M ratio = 0.98). CONCLUSIONS: Concurrent implementation of multiple, targeted CBCT modalities can reduce sex disparities in HIV testing in South Africa. Given the acceptability and accessibility of these CBCT services to adolescent girls and young women, evident from their high testing rates, leveraging community-based services delivery platforms to increase access to HIV prevention services, including pre-exposure prophylaxis (PrEP), should be considered.

"I got tested at home, the help came to me": acceptability and feasibility of home-based TB testing of household contacts using portable molecular diagnostics in South Africa.

OBJECTIVE: The effectiveness of household contact investigations is limited by low referral uptake for clinic-based TB testing by symptomatic household contacts. We qualitatively investigated the acceptability and perceived benefits of home-based TB testing using a portable GeneXpert-I instrument (GX-I) in an urban South African township. METHODS: In-depth interviews were conducted with household contacts tested and those that observed testing. Semi-structured interviews explored household contact's understanding of TB, perceptions of the GX-I device and testing procedures, confidentiality, willingness to refer others, and views on home- vs. clinic-based testing. Focus group discussions with home-based TB testing implementing staff assessed operational considerations for scale-up. Data were analysed using a constant comparison approach to qualitatively evaluate the acceptability and feasibility of home-based TB testing. RESULTS: Thirty in-depth interviews and two focus group discussions were conducted. Observing one's own sputum being tested resulted in an emergent trust in home-based TB testing, the GX-I device and one's test results. Home-based TB testing was considered convenient, helped to overcome apathy towards testing and mitigated barriers to clinic-based testing. Perceptions that home-based TB testing contributes to improved household and community health resulted in an emergent theme of alleviation of health insecurities. Operational concerns regarding inadvertent disclosure of one's diagnosis to household members and time spent in people's homes were identified. CONCLUSIONS: Home-based TB testing was acceptable and feasible. Individuals expressed belief in the machine by being able to witness the testing process. Though most themes mirrored qualitative studies of home-based HIV testing, the alleviation of health insecurities theme is unique to home-based TB testing. Future research must evaluate the impact of home-based TB testing on case finding yield, time-to-treatment initiation and household outcomes.

OBJECTIF: L'efficacité des enquêtes sur les contacts familiaux est limitée par le faible taux de respect de l'orientation pour le dépistage de la tuberculose (TB) en clinique par les contacts familiaux symptomatiques. Nous avons investigué qualitativement l'acceptabilité et les avantages perçus du dépistage de la TB à domicile à l'aide d'un dispositif portable GeneXpert-I (GX-I) dans une ville urbaine sud-africaine. MÉTHODES: Des entretiens approfondis ont été menés avec des contacts familiaux testés et ceux qui ont observé la pratique des tests. Des entretiens semi-structurés ont permis d'explorer la compréhension de la TB par les contacts familiaux, les perceptions sur le dispositif GX-I et les procédures de test, la confidentialité, la volonté de référer d'autres personnes et les opinions sur le dépistage à domicile ou en clinique. Des discussions de groupe focalisées avec le personnel chargé de la mise en œuvre du dépistage de la TB à domicile ont évalué les considérations opérationnelles pour le déploiement. Les données ont été analysées en utilisant une approche de comparaison constante pour évaluer qualitativement l'acceptabilité et la faisabilité du dépistage de la TB à domicile. RÉSULTATS: Trente entretiens approfondis et deux discussions de groupe ont été menés. L'observation de ses propres expectorations testées a conduit à une émergente de confiance dans le dépistage de la TB à domicile, le dispositif GX-I et les résultats des tests. Le dépistage de la TB à domicile était considéré comme pratique, aidait à surmonter l'apathie envers le dépistage et atténuait les obstacles au dépistage en clinique. La perception selon laquelle le dépistage de la TB à domicile contribue à l'amélioration de la santé des ménages et de la communauté a donné lieu à l'émergence du thème de la réduction des insécurités sanitaires. Des préoccupations opérationnelles concernant la divulgation par inadvertance de son diagnostic aux membres du ménage et le temps passé au domicile des personnes ont été identifiées. CONCLUSION: Le dépistage de la TB à domicile était acceptable et faisable. Les individus ont exprimé leur croyance en la machine en étant en mesure d'assister au processus de test. Bien que la plupart des thèmes reflètent des études qualitatives sur le dépistage du VIH à domicile, le thème de l'atténuation des insécurités sanitaires est unique au dépistage de la TB à domicile. Les recherches futures doivent évaluer l'impact du dépistage de la TB à domicile sur le rendement de la recherche des cas, le délai de mise en route du traitement et les résultats au sein des ménages.
