Community-based antiretroviral therapy versus standard clinic-based services for HIV in South Africa and Uganda (DO ART): a randomised trial

Strengthening person-centered care through quality improvement: a mixed-methods study examining implementation of the Person-Centered Care Assessment Tool in Zambian health facilities

INTRODUCTION

Person-centered care (PCC) is considered a fundamental approach to address clients' needs. There is a dearth of data on specific actions that HIV treatment providers identify as priorities to strengthen PCC.

OBJECTIVE

This study team developed the Person-Centered Care Assessment Tool (PCC-AT), which measures PCC service delivery within HIV treatment settings. The PCC-AT, including subsequent group action planning, was implemented across 29 facilities in Zambia among 173 HIV treatment providers. Mixed-methods study objectives included: (1) identify types of PCC-strengthening activities prioritized based upon low and high PCC-AT scores; (2) identify common themes in PCC implementation challenges and action plan activities by low and high PCC-AT score; and (3) determine differences in priority actions by facility ART clinic volume or geographic type.

METHODS

The study team conducted thematic analysis of action plan data and cross-tabulation queries to observe patterns across themes, PCC-AT scores, and key study variables.

RESULTS

The qualitative analysis identified 39 themes across 29 action plans. A higher proportion of rural compared to urban facilities identified actions related to stigma and clients' rights training; accessibility of educational materials and gender-based violence training. A higher proportion of urban and peri-urban compared to rural facilities identified actions related to community-led monitoring.

DISCUSSION

Findings provide a basis to understand common PCC weaknesses and activities providers perceive as opportunities to strengthen experiences in care.

CONCLUSION

To effectively support clients across the care continuum, systematic assessment of PCC services, action planning, continuous quality improvement interventions and re-measurements may be an important approach.

Preferences for Hypertension Care in Malawi: A Discrete Choice Experiment Among People Living with Hypertension, With and Without HIV

Hypertension is the most common non-communicable disease diagnosed among people in sub-Saharan Africa. However, little is known about client preferences for hypertension care. We performed a discrete choice experiment in Malawi among people with hypertension, with and without HIV. Participants were asked to select between two care scenarios, each with six attributes: distance, waiting time, provider friendliness, individual or group care, antihypertensive medication supply, and antihypertensive medication dispensing frequency (three versus one month). Eight choice sets (each with two scenarios) were presented to each individual. Mixed effects logit models quantified preferences for each attribute. Estimated model coefficients were used to predict uptake of hypothetical models of care. Between July 2021 and April 2022 we enrolled 1003 adults from 14 facilities in Malawi; half were living with HIV and on ART for a median of 11 years. Median age of respondents was 57 years (IQR 49-63), 58.2% were female, and median duration on antihypertensive medications was 4 years (IQR 2-7). Participants strongly preferred seeing a provider alone versus in a group (OR 11.3, 95% CI 10.4-12.3), with stronger preference for individual care among those with HIV (OR 15.4 versus 8.6, p < 0.001). Three-month versus monthly dispensing was also strongly preferred (OR 4.2; 95% CI 3.9-4.5). 72% of respondents would choose group care if all other facility attributes were favorable, although PLHIV were less likely to make this trade-off (66% versus 77%). These findings have implications for the scale-up of hypertension care in Malawi and similar settings.

Continuity of care during severe civil unrest with a model of community-based HIV care: a retrospective cohort study from Haiti

Background

There are limited data on the effectiveness of differentiated service delivery (DSD) for HIV care during sociopolitical turmoil. We assessed outcomes with a DSD model of care that includes patient choice between community-based antiretroviral therapy (ART) centres, home-based ART dispensing, or facility-based care at GHESKIO clinic during a period of severe civil unrest in Port-au-Prince, Haiti.

Methods

This retrospective analysis included data on patients with at least one HIV visit at GHESKIO between May 1, 2019, and December 31, 2021. Multivariable logistic regression models were used to assess predictors of attending ≥1 community visit during the study period, and failure to attend timely visits. HIV-1 RNA test results were reported among patients who had been ART for ≥3 months at last visit.

Findings

Of the 18,625 patients included in the analysis, 9659 (51.9%) attended at least one community visit. The proportion of community visits ranged from 0.3% (2019) to 44.1% (2021). Predictors of ≥1 community visit included male sex (aOR: 1.13; 95% CI: 1.06, 1.20), secondary education (aOR: 1.07; 95% CI: 1.01, 1.14), income > $USD 1.00/day (aOR: 1.24; 95% CI: 1.14, 1.35), longer duration on ART (aOR: 1.08 per additional year; 95% CI: 1.07, 1.09), and residence in Carrefour/Gressier (p < 0.0001 in comparisons with all other zones). Younger age and shorter time on ART were associated with late visits and loss to follow-up. Among 12,586 patients with an on-time final visit who had been on ART for ≥3 months, 11,131 (88.4%) received a viral load test and 9639 (86.6%) had HIV-1 RNA < 1000 copies/mL.

Interpretation

The socio-political situation in Haiti has presented extraordinary challenges to the health care system, but retention and viral suppression rates remain high with a model of community-based HIV care. Additional interventions are needed to improve outcomes for younger patients, and those with shorter time on ART.

'Not taking medications and taking medication, it was the same thing:' perspectives of antiretroviral therapy among people hospitalised with advanced HIV disease

BACKGROUND

Despite HIV's evolution to a chronic disease, the burden of advanced HIV disease (AHD, defined as a CD4 count of < 200 cells/uL or WHO clinical Stage 3 or 4 disease), remains high among People Living with HIV (PLHIV) who have previously been prescribed antiretroviral therapy (ART). As little is known about the experiences of patients hospitalised with AHD, this study sought to discern social forces driving hospitalisation with AHD. Understanding such forces could inform strategies to reduce HIV-related morbidity and mortality.

METHODS

We conducted a qualitative study with patients hospitalised with AHD who had a history of poor adherence. Semi-structured interviews were conducted between October 1 and November 30, 2023. The Patient Health Engagement and socio-ecological theoretical models were used to guide a thematic analysis of interview transcripts.

RESULTS

Twenty individuals participated in the research. Most reported repeated periods of disengagement with HIV services. The major themes identified as driving disengagement included: 1) feeling physically well; 2) life circumstances and relationships; and 3) health system factors, such as clinic staff attitudes and a perceived lack of flexible care. Re-engagement with care was often driven by new physical symptoms but was mediated through life circumstances/relationships and aspects of the health care system.

CONCLUSIONS

Current practices fail to address the challenges to lifelong engagement in HIV care. A bold strategy for holistic care which involves people living with advanced HIV as active members of the health care team (i.e. 'PLHIV as Partners'), could contribute to ensuring health care services are compatible with their lives, reducing periods of disengagement from care.

A mixed methods process evaluation: understanding the implementation and delivery of HIV prevention services integrated within sexual reproductive health (SRH) with or without peer support amongst adolescents and young adults in rural KwaZulu-Natal, South Africa

BACKGROUND

Combination prevention interventions, when integrated with community-based support, have been shown to be particularly beneficial to adolescent and young peoples' sexual and reproductive health. Between 2020 and 2022, the Africa Health Research Institute in rural South Africa conducted a 2 × 2 randomised factorial trial among young people aged 16-29 years old (Isisekelo Sempilo) to evaluate whether integrated HIV and sexual and reproductive health (HIV/SRH) with or without peer support will optimise delivery of HIV prevention and care. Using mixed methods, we conducted a process evaluation to provide insights to and describe the implementation of a community-based peer-led HIV care and prevention intervention targeting adolescents and young people.

METHODS

The process evaluation was conducted in accordance with the Medical Research Council guidelines using quantitative and qualitative approaches. Self-completed surveys and clinic and programmatic data were used to quantify the uptake of each component of the intervention and to understand intervention fidelity and reach. In-depth individual interviews were used to understand intervention experiences. Baseline sociodemographic factors were summarised for each trial arm, and proportions of participants who accepted and actively engaged in various components of the intervention as well as those who successfully linked to care were calculated. Qualitative data were thematically analysed.

RESULTS

The intervention was feasible and acceptable to young people and intervention implementing teams. In particular, the STI testing and SRH components of the intervention were popular. The main challenges with the peer support implementation were due to fidelity, mainly because of the COVID-19 pandemic. The study found that it was important to incorporate familial support into interventions for young people's sexual health. Moreover, it was found that psychological and social support was an essential component to combination HIV prevention packages for young people.

CONCLUSION

The results demonstrated that peer-led community-based care that integrates SRH services with HIV is a versatile model to decentralise health and social care. The family could be a platform to target restrictive gender and sexual norms, by challenging not only attitudes and behaviours related to gender among young people but also the gendered structures that surround them.

The impact of primary health care on AIDS incidence and mortality: A cohort study of 3.4 million Brazilians

BACKGROUND

Primary Health Care (PHC) is essential for effective, efficient, and more equitable health systems for all people, including those living with HIV/AIDS. This study evaluated the impact of the exposure to one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality.

METHODS AND FINDINGS

A retrospective cohort study carried out in Brazil from January 1, 2007 to December 31, 2015. We conducted an impact evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the impact of FHS on AIDS incidence and mortality and compared outcomes between residents of municipalities with low or no FHS coverage (unexposed) with those in municipalities with 100% FHS coverage (exposed). We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated the FHS impact by sex and age and performed a wide range of sensitivity and triangulation analyses; 100% FHS coverage was associated with lower AIDS incidence (rate ratio [RR]: 0.76, 95% CI: 0.68 to 0.84) and mortality (RR: 0.68, 95%CI: 0.56 to 0.82). FHS impact was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR: 0.62, 95% CI: 0.53 to 0.72) and mortality (RR: 0.56, 95% CI: 0.43 to 0.72). The absence of important confounding variables (e.g., sexual behavior) is a key limitation of this study.

CONCLUSIONS

AIDS should be an avoidable outcome for most people living with HIV today and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

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.

Traditional healer support to improve HIV viral suppression in rural Uganda (Omuyambi): study protocol for a cluster randomized hybrid effectiveness-implementation trial

BACKGROUND

Rural African people living with HIV face significant challenges in entering and remaining in HIV care. In rural Uganda, for example, there is a threefold higher prevalence of HIV compared to the national average and lower engagement throughout the HIV continuum of care. There is an urgent need for appropriate interventions to improve entry and retention in HIV care for rural Ugandans with HIV. Though many adults living with HIV in rural areas prioritize seeking care services from traditional healers over formal clinical services, healers have not been integrated into HIV care programs. The Omuyambi trial is investigating the effectiveness of psychosocial support delivered by traditional healers as an adjunct to standard HIV care versus standard clinic-based HIV care alone. Additionally, we are evaluating the implementation process and outcomes, following the Consolidated Framework for Implementation Research.

METHODS

This cluster randomized hybrid type 1 effectiveness-implementation trial will be conducted among 44 traditional healers in two districts of southwestern Uganda. Healers were randomized 1:1 into study arms, where healers in the intervention arm will provide 12 months of psychosocial support to adults with unsuppressed HIV viral loads receiving care at their practices. A total of 650 adults with unsuppressed HIV viral loads will be recruited from healer clusters in the Mbarara and Rwampara districts. The primary study outcome is HIV viral load measured at 12 months after enrollment, which will be analyzed by intention-to-treat. Secondary clinical outcome measures include (re)initiation of HIV care, antiretroviral therapy adherence, and retention in care. The implementation outcomes of adoption, fidelity, appropriateness, and acceptability will be evaluated through key informant interviews and structured surveys at baseline, 3, 9, 12, and 24 months. Sustainability will be measured through HIV viral load measurements at 24 months following enrollment.

DISCUSSION

The Omuyambi trial is evaluating an approach that could improve HIV outcomes by incorporating previously overlooked community lay supporters into the HIV cascade of care. These findings could provide effectiveness and implementation evidence to guide the development of policies and programs aimed at improving HIV outcomes in rural Uganda and other countries where healers play an essential role in community health.

Increasing HIV testing and linkage to care among men in rural South Africa using conditional financial incentives and a decision support app: A process evaluation

Men in sub-Saharan Africa are less likely to accept HIV testing and link to HIV care than women. We conducted a trial to investigate the impact of conditional financial incentives and a decision support application, called EPIC-HIV, on HIV testing and linkage to care. We report the findings of the trial process evaluation to explore whether the interventions were delivered as intended, identify mechanisms of impact and any contextual factors that may have impacted the trial outcomes. Between August 2018 and March 2019, we conducted in-depth interviews and focus group discussions with trial participants (n = 31) and staff (n = 14) to examine views on the implementation process, participant responses to the interventions and the external factors that may have impacted the implementation and outcomes of the study. Interviews were audio-recorded, transcribed, and translated where necessary, and thematically analyzed using ATLAS-ti and NVivo. Both interventions were perceived to be acceptable and useful by participants and implementers. EPIC-HIV proved challenging to implement as intended because it was difficult to ensure consistent use of earphones, and maintenance of privacy. Some participants struggled to navigate the EPIC-HIV app independently and select stories that appealed to them without support. Some participants stopped exploring the app before the end, resulting in an incomplete use of EPIC-HIV. While the financial incentive was implemented as intended, there were challenges with eligibility. The convenience and privacy of home testing influenced the uptake of HIV testing. Contextual barriers including fear of HIV stigma and disclosure if diagnosed with HIV, and expectations of poor treatment in clinics may have inhibited linkage to care. Financial incentives were relatively straightforward to implement and increased uptake of home-based rapid HIV testing but were not sufficient as a 'stand-alone' intervention. Barriers like fear of stigma should be addressed to facilitate linkage to care.

Costs of home-delivered antiretroviral therapy refills for persons living with HIV: evidence from a pilot randomized controlled trial in KwaZulu-Natal, South Africa

Antiretroviral therapy (ART) is needed across the lifetime to maintain viral suppression for people living with HIV. In South Africa, obstacles to reliable access to ART persist and are magnified in rural areas, where HIV services are also typically costlier to deliver. A recent pilot randomized study (the Deliver Health Study) found that home-delivered ART refills, provided at a low user fee, effectively overcame logistical barriers to access and improved clinical outcomes in rural South Africa. In the present costing study using the payer perspective, we conducted retrospective activity-based micro-costing of home-delivered ART within the Deliver Health Study and when provided at-scale (in a rural setting), and compared to facility-based costs using provincial expenditure data (covering both rural and urban settings). Within the context of the pilot Deliver Health Study which had an average of three deliveries per day for three days a week, home-delivered ART cost (in 2022 USD) $794 in the first year and $714 for subsequent years per client after subtracting client fees, compared with $167 per client in provincial clinic-based care. We estimated that home-delivered ART can reasonably be scaled up to 12 home deliveries per day for five days per week in the rural setting. When delivered at scale, home-delivered ART cost $267 in the first year and $183 for subsequent years per client. Average costs of home delivery further decreased when increasing the duration of refills from three-months to six- and 12-month scripts (from $183 to $177 and $135 per client, respectively). Personnel costs were the largest cost for home-delivered refills while ART drug costs were the largest cost of clinic-based refills. When provided at scale, home-delivered ART in a rural setting not only offers clinical benefits for a hard-to-reach population but is also comparable in cost to the provincial standard of care.

Preventing tuberculosis with community-based care in an HIV-endemic setting: a modelling analysis

INTRODUCTION

Antiretroviral therapy (ART) and tuberculosis preventive treatment (TPT) both prevent tuberculosis (TB) disease and deaths among people living with HIV. Differentiated care models, including community-based care, can increase the uptake of ART and TPT to prevent TB in settings with a high burden of HIV-associated TB, particularly among men.

METHODS

We developed a gender-stratified dynamic model of TB and HIV transmission and disease progression among 100,000 adults ages 15-59 in KwaZulu-Natal, South Africa. We drew model parameters from a community-based ART initiation and resupply trial in sub-Saharan Africa (Delivery Optimization for Antiretroviral Therapy, DO ART) and other scientific literature. We simulated the impacts of community-based ART and TPT care programmes during 2018-2027, assuming that community-based ART and TPT care were scaled up to similar levels as in the DO ART trial (i.e. ART coverage increasing from 49% to 82% among men and from 69% to 83% among women) and sustained for 10 years. We projected the number of TB cases, deaths and disability-adjusted life years (DALYs) averted relative to standard, clinic-based care. We calculated programme costs and incremental cost-effectiveness ratios from the provider perspective.

RESULTS

If community-based ART care could be implemented with similar effectiveness to the DO ART trial, increased ART coverage could reduce TB incidence by 27.0% (range 21.3%-34.1%) and TB mortality by 34.6% (range 24.8%-42.2%) after 10 years. Increasing both ART and TPT uptake through community-based ART with TPT care could reduce TB incidence by 29.7% (range 23.9%-36.0%) and TB mortality by 36.0% (range 26.9%-43.8%). Community-based ART with TPT care reduced gender disparities in TB mortality rates, with a projected 54 more deaths annually among men than women (range 11-103) after 10 years of community-based care versus 109 (range 41-182) in standard care. Over 10 years, the mean cost per DALY averted by community-based ART with TPT care was $846 USD (range $709-$1012).

CONCLUSIONS

By substantially increasing coverage of ART and TPT, community-based care for people living with HIV could reduce TB incidence and mortality in settings with high burdens of HIV-associated TB and reduce TB gender disparities.

Improving linkage to HIV care following a reactive HIV self-testing result among men in KwaZulu-Natal, South Africa

BACKGROUND

Despite the many interventions that have been implemented in sub-Saharan Africa to improve the uptake of HIV testing and antiretroviral (ART) initiation services, the rates at which men are tested for HIV and initiated on ART have remained consistently lower compared to those for women. We aim to investigate barriers and facilitators for linkage to care following HIVST positive results among men aged between 18 and 49 years, and use these findings to design an intervention to improve linkage to care among men in a high-HIV prevalent district in KwaZulu-Natal province, South Africa.

METHODS

This multi-method study will be conducted over 24 months in eight purposively selected HIV testing and treatment facilities from December 2023 to November 2025. For the quantitative component, a sample of 197 HIV positive men aged 18-49 years old who link to care after HIV self-test (HIVST) will be recruited into the study. HIVST kits will be distributed to a minimum of 3000 men attending community services through mobile clinics that are supported by the Health Systems Trust, at different service delivery points, including schools, taxi ranks and other hotspots. The qualitative component will consist of in-depth interviews (IDIs) with 15 HIVST users and IDIs with 15 key informants. To design and develop acceptable, feasible, effective, and sustainable models for improving linkage to care, three groups of HIVST users (2*positive (N = 12) and 1*negative (N = 12)) will be purposively select to participate in a design workshop. Chi square tests will be used to identify social and demographic factors associated with linkage, while logistic regression will be used to identify independent factors. Kaplan Meier curves and cox proportional hazard models will be used to identify factors associated with time to event. Content and thematic approaches will be used to analyze the qualitative data.

DISCUSSION

There remains an urgent need for designing and implementing innovative intervention strategies that are convenient and tailored for addressing the needs of men for improving HIV testing and linkage to care at early stages in resource-limited settings, to improve individual health outcomes, reduce transmission from HIV and minimize HIV-related mortality rates. Our proposed study offers several important innovations aimed at improving linkage to care among men. Our study targets men, as they lag the HIV continuum but are also under-researched in public health studies.

Comparing PrEP initiation rates by service delivery models among high risk adolescent boys and young men in KwaZulu-Natal, South Africa: findings from a population-based prospective study

INTRODUCTION

Pre-exposure prophylaxis (PrEP) is an HIV prevention strategy that can reduce the risk of HIV acquisition by more than 90% if taken consistently. Although South Africa has been implementing PrEP since 2016, initially for selected population groups before expanding access to more people, there is a dearth of research focused on PrEP among adolescent boys and young men (ABYM), despite them experiencing high rates of HIV infection. To address this gap, we compared PrEP initiation rates by service delivery points (SDPs) among ABYM in KwaZulu-Natal, South Africa.

METHODS

We conducted a population-based prospective study in 22 SDPs from July 2021 to July 2022 in KwaZulu-Natal, South Africa. Sexually active ABYM aged 15-35 years who tested HIV negative were recruited at purposively selected PrEP SDPs (i.e., healthcare facilities, secondary schools and Technical Vocational Education and Training (TVET) colleges, and community-based youth zones). We collected baseline quantitative data from each participant using self-administered electronic questionnaires built into REDCap, including demographic information such as age, sex, employment status and level of education, as well as PrEP initiation outcomes. We extracted data from REDCap and exported it to Stata version 17.0 for analysis, and then eliminated discrepancies and removed duplicates. We described baseline characteristics using summary and descriptive statistics (median, interquartile range [IQR] and proportions) and reported PrEP initiation proportions overall and by SDPs.

RESULTS

The study included 1104 ABYM, with a median age of 24 years (interquartile range (IQR): 21-28)). Almost all participants were black African (n = 1090, 99%), with more than half aged 15-24 years (n = 603, 55%) and 45% (n = 501) aged 25-35 years. The majority (n = 963; 87%) had attained a secondary level of education. Overall PREP initiation rate among adolescent boys and young men was low: among 1078 participants who were eligible for PrEP, 13% (n = 141) were started on PrEP. Among the participants who were initiated on PrEP, over three quarters (78%, n = 58) were initiated from high schools, compared with community-based youth zones (40%, n = 37), TVET colleges (26%, n = 16) and healthcare facilities (4%, n = 30).

CONCLUSIONS

This study provided evidence suggesting that expanding PrEP services to non-traditional settings, such as high schools, TVET colleges, and community-based organizations, may have a potential to increase PrEP access among ABYM in South Africa.

HIV Viral Load Patterns and Risk Factors Among Women in Prevention of Mother-To-Child Transmission Programs to Inform Differentiated Service Delivery

BACKGROUND

Differentiated service delivery (DSD) approaches decrease frequency of clinic visits for individuals who are stable on antiretroviral therapy. It is unclear how to optimize DSD models for postpartum women living with HIV (PWLH). We evaluated longitudinal HIV viral load (VL) and cofactors, and modelled DSD eligibility with virologic failure (VF) among PWLH in prevention of mother-to-child transmission programs.

METHODS

This analysis used programmatic data from participants in the Mobile WAChX trial (NCT02400671). Women were assessed for DSD eligibility using the World Health Organization criteria among general people living with HIV (receiving antiretroviral therapy for ≥6 months and having at least 1 suppressed VL [<1000 copies/mL] within the past 6 months). Longitudinal VL patterns were summarized using group-based trajectory modelling. VF was defined as having a subsequent VL ≥1000 copies/mL after being assessed as DSD-eligible. Predictors of VF were determined using log-binomial models among DSD-eligible PWLH.

RESULTS

Among 761 women with 3359 VL results (median 5 VL per woman), a 3-trajectory model optimally summarized longitudinal VL, with most (80.8%) women having sustained low probability of unsuppressed VL. Among women who met DSD criteria at 6 months postpartum, most (83.8%) maintained viral suppression until 24 months. Residence in Western Kenya, depression, reported interpersonal abuse, unintended pregnancy, nevirapine-based antiretroviral therapy, low-level viremia (VL 200-1000 copies/mL), and drug resistance were associated with VF among DSD-eligible PWLH.

CONCLUSIONS

Most postpartum women maintained viral suppression from early postpartum to 24 months and may be suitable for DSD referral. Women with depression, drug resistance, and detectable VL need enhanced services.

Differentiated care for youth in Zimbabwe: Outcomes across the HIV care cascade

Youth living with HIV are at higher risk than adults of disengaging from HIV care. Differentiated models of care such as community delivery of antiretroviral therapy (ART) may improve treatment outcomes. We investigated outcomes across the HIV cascade among youth accessing HIV services in a community-based setting. This study was nested in a cluster-randomised controlled trial (CHIEDZA: Clinicaltrials.gov, Registration Number: NCT03719521) conducted in three provinces in Zimbabwe and aimed to investigate the impact of a youth-friendly community-based package of HIV services, integrated with sexual and reproductive health services for youth (16-24 years), on population-level HIV viral load (VL). HIV services included HIV testing, ART initiation and continuous care, VL testing, and adherence support. Overall 377 clients were newly diagnosed with HIV at CHIEDZA, and linkage to HIV care was confirmed for 265 (70.7%, 234 accessed care at CHIEDZA and 31 with other providers); of these 250 (94.3%) started ART. Among those starting ART at CHIEDZA who did not transfer out and had enough follow up time (>6 months), 38% (68/177) were lost-to-follow-up within six months. Viral suppression (HIV Viral Load <1000 copies/ml) among those who had a test at 6 months was 90% (96/107). In addition 1162 clients previously diagnosed with HIV accessed CHIEDZA; 714 (61.4%) had a VL test, of whom 565 (79.1%) were virally suppressed. This study shows that provision of differentiated services for youth in the community is feasible. Linkage to care and retention during the initial months of ART was the main challenge and needs concerted attention to achieve the ambitious 95-95-95 UNAIDS targets.

HIV epidemiology, prevention, treatment, and implementation strategies for public health

The global HIV response has made tremendous progress but is entering a new phase with additional challenges. Scientific innovations have led to multiple safe, effective, and durable options for treatment and prevention, and long-acting formulations for 2-monthly and 6-monthly dosing are becoming available with even longer dosing intervals possible on the horizon. The scientific agenda for HIV cure and remission strategies is moving forward but faces uncertain thresholds for success and acceptability. Nonetheless, innovations in prevention and treatment have often failed to reach large segments of the global population (eg, key and marginalised populations), and these major disparities in access and uptake at multiple levels have caused progress to fall short of their potential to affect public health. Moving forward, sharper epidemiologic tools based on longitudinal, person-centred data are needed to more accurately characterise remaining gaps and guide continued progress against the HIV epidemic. We should also increase prioritisation of strategies that address socio-behavioural challenges and can lead to effective and equitable implementation of existing interventions with high levels of quality that better match individual needs. We review HIV epidemiologic trends; advances in HIV prevention, treatment, and care delivery; and discuss emerging challenges for ending the HIV epidemic over the next decade that are relevant for general practitioners and others involved in HIV care.

Factors associated with HIV-positive status awareness among adults with long term HIV infection in four countries in the East and Southern Africa region: A multilevel approach

Antiretroviral treatment (ART) appropriately and regularly used decreases the human immunodeficiency virus (HIV) viral load in the bloodstream, preventing HIV-infected people from spreading the infection to others. Disparities in ART adoption persists in East and Southern Africa, with low HIV-positive status knowledge being the primary factor. We investigated individual and household characteristics of HIV-positive status awareness among adults with long-term HIV infection in four East and Southern African countries: Eswatini, Malawi, Tanzania, and Zimbabwe. The study analyzed data from surveys conducted in Eswatini, Malawi, Tanzania, and Zimbabwe in 2015-2016. Only individuals who tested positive for HIV through rapid tests were included in the analysis. Those who already knew they were HIV-positive were categorized as aware, while those who reported being negative, never tested, or didn't know their status were categorized as unaware. Statistical models were used to examine various factors related to HIV awareness. Pooled and country-specific odds ratios were computed. The percentage of people who knew they had HIV ranged from 58% (Tanzania and Malawi) to 87% (Eswatini). After adjusting for other variables, young persons in all countries were less likely to be aware of their HIV-positive status. Gender, marital status, education, working status, household wealth, and urbanization level of households were also associated with HIV-positive status awareness but inconsistent across countries. HIV-positive status awareness in these four East and Southern African nations remained unsatisfactory as compared to the United Nations' 95% guideline, indicating that testing and knowledge of HIV testing in this region still has a lot of potential for improvement. The observed variations among nations may be attributable to differences in HIV pandemic culture and policies. The findings of this study will assist governments determining which subpopulations to target to boost adoption of HIV testing services, as well as in designing and development of policies.

Systematic Review and Meta-analysis of Linkage to HIV Care Interventions in the United States, Canada, and Ukraine (2010-2021)

We conducted a systematic review and meta-analysis of interventions targeting linkage to HIV care in the US, Canada, and Europe. We searched six databases (PubMed, Embase, Cochrane Library, Web of Science and CINAHL). Inclusion criteria were English language studies in adults in the US, Canada, or Europe, published January 1, 2010 to January 1, 2021. We synthesized interventions by type and linkage to care outcome. The outcome was cumulative incidence of 3-month linkage. We estimated cumulative incidence ratios of linkage with 95% confidence intervals (CIs). We screened 945 studies; 13 met selection criteria (n = 1 from Canada, n = 1 from Ukraine, n = 11 from the US) and were included after full text review (total 37,549 individuals). The cumulative incidence of 3-month linkage in the intervention group was 0.82 (95% CI 0.68-0.94) and control group 0.71 (95% CI 0.50-0.90); cIR of linkage for intervention versus control was 1.30 (95% CI 1.13, 1.49). Interventions to improve linkage to care after HIV diagnosis warrant further attention.

Barriers and facilitators for interventions to improve ART adherence in Sub-Saharan African countries: A systematic review and meta-analysis

BACKGROUND

The HIV/AIDS pandemic remains a significant public health issue, with sub-Saharan Africa (SSA) at its epicentre. Although antiretroviral therapy (ART) has been introduced to decrease new infections and deaths, SSA reports the highest incidence of HIV/AIDS, constituting two-thirds of the global new infections. This review aimed to elucidate the predominant barriers and facilitators influencing ART adherence and to identify effective strategies to enhance ART adherence across SSA.

METHODS

A comprehensive review was conducted on studies examining barriers to ART adherence and interventions to boost adherence among HIV-positive adults aged 15 and above in SSA, published from January 2010 onwards. The research utilized databases like Medline Ovid, CINAHL, Embase, and Scopus. Included were experimental and quasi-experimental studies, randomized and non-randomized controlled trials, comparative before and after studies, and observational studies such as cross-sectional, cohort, prospective and retrospective studies. Two independent reviewers screened the articles, extracted pertinent data, and evaluated the studies' methodological integrity using Joanna Briggs Institute's standardized appraisal tools. The compiled data underwent both meta-analysis and narrative synthesis.

RESULTS

From an initial pool of 12,538 papers, 45 were selected (30 for narrative synthesis and 15 for meta-analysis). The identified barriers and facilitators to ART adherence were categorized into seven principal factors: patient-related, health system-related, medication-related, stigma, poor mental health, socioeconomic and socio-cultural-related factors. Noteworthy interventions enhancing ART adherence encompassed counselling, incentives, mobile phone short message service (SMS), peer delivered behavioural intervention, community ART delivery intervention, electronic adherence service monitoring device, lay health worker lead group intervention and food assistance. The meta-analysis revealed a statistically significant difference in ART adherence between the intervention and control groups (pooled OR = 1.56, 95%CI:1.35-1.80, p = <0.01), with evidence of low none statistically significant heterogeneity between studies (I2 = 0%, p = 0.49).

CONCLUSION

ART adherence in SSA is influenced by seven key factors. Multiple interventions, either standalone or combined, have shown effectiveness in enhancing ART adherence. To optimize ART's impact and mitigate HIV's prevalence in SSA, stakeholders must consider these barriers, facilitators, and interventions when formulating policies or treatment modalities. For sustained positive ART outcomes, future research should target specific underrepresented groups like HIV-infected children, adolescents, and pregnant women in SSA to further delve into the barriers, facilitators and interventions promoting ART adherence.

Same-day ART initiation, loss to follow-up and viral load suppression among people living with HIV in low- and middle-income countries: systematic review and meta-analysis

Introduction

in 2015, the World Health Organization recommended early antiretroviral therapy (ART) initiation after HIV diagnosis. Mixed results on the effect of same-day ART initiation (SDI) over non-same-day ART initiation (NSDI) on loss to follow-up (LTFU) and viral load suppression (VLS) necessitate further evaluation.

Methods

this was a systematic review and meta-analysis of people living with HIV in low- and middle-income countries (LMICs). Multiple databases were searched from January 2016 to December 2022. VLS was defined as HIV RNA <1,000 or <400 cells/ml, depending on the study. Forest plots were used to present the pooled prevalence and 95% confidence intervals (CIs). Heterogeneity was tested by an I2 statistic and a p-value of <0.05 indicated its presence. Analyses were performed in STATA.

Results

sixteen studies (5 clinical trials, 10 cohorts, and 1 cross-sectional) were included in the final analysis. Nine studies with 157,633 people living with HIV were analyzed for LTFU and the pooled prevalence of LTFU was 22.0% (95%CI; 18.5-25.7). The pooled prevalence of VLS was 72.7% (95%CI; 65.4-79.5%). The I2 statistic had a Q value of 200.62 (p<0.001) and 44.63 (p<0.001) for pooled prevalence of LTFU and VLS, respectively. Overall, compared to those who received NSDI, SDI had a significantly increased risk of LTFU (risk difference (RD)=0.04; 95%CI: 0.01-0.07). Although observational studies showed an increased risk of LTFU among SDI compared to NSDI (RD=0.05, 95%CI: 0.02-0.08), clinical trials did not. There was no statistically significant difference in VLS comparing those who received SDI vs NSDI (RD= 0.02, 95%CI: -0.03 - 0.07).

Conclusion

nearly two in ten people living with HIV in LMICs who initiated ART were LTFU. SDI was associated with increased risk of LTFU. Efforts to prevent LTFU among those who receive SDI are critical to maximize its potential benefits.

Prior exposure to antiretroviral therapy among adult patients presenting for HIV treatment initiation or reinitiation in sub-Saharan Africa: a systematic review

OBJECTIVES

As countries have scaled up access to antiretroviral therapy (ART) for HIV, attrition rates of up to 30% annually have created a large pool of individuals who initiate treatment with prior ART experience. Little is known about the proportion of non-naïve reinitiators within the population presenting for treatment initiation.

DESIGN

Systematic review of published articles and abstracts reporting proportions of non-naïve adult patients initiating ART in sub-Saharan Africa.

DATA SOURCES

PubMed, Embase Elsevier, Web of Science Core Collection, International AIDS Society conferences, Conference on Retroviruses and Opportunistic Infections conferences.

ELIGIBILITY CRITERIA

Clinical trials and observational studies; reporting on adults in sub-Saharan Africa who initiated lifelong ART; published in English between 1 January 2018 and 11 July 2023 and with data collected after January 2016. Initiator self-report, laboratory discernment of antiretroviral metabolites, and viral suppression at initiation or in the medical record were accepted as evidence of prior exposure.

DATA EXTRACTION AND SYNTHESIS

We captured study and sample characteristics, proportions with previous ART exposure and the indicator of previous exposure reported. We report results of each eligible study, estimate the risk of bias and identify gaps in the literature.

RESULTS

Of 2740 articles, 11 articles describing 12 cohorts contained sufficient information for the review. Proportions of initiators with evidence of prior ART use ranged from 5% (self-report only) to 53% (presence of ART metabolites in hair or blood sample). The vast majority of screened studies did not report naïve/non-naïve status. Metrics used to determine and report non-naïve proportions were inconsistent and difficult to interpret.

CONCLUSIONS

The proportion of patients initiating HIV treatment who are truly ART naïve is not well documented. It is likely that 20%-50% of ART patients who present for ART are reinitiators. Standard reporting metrics and diligence in reporting are needed, as is research to understand the reluctance of patients to report prior ART exposure.

The prevalence of suicidal behaviour and its associated risk factors among school-going adolescents resident in the United Arab Emirates

Suicidal behaviour which includes suicidal ideation, having a plan to commit suicide and suicide attempts remains a global public health issue as it substantially impacts adolescent health and wellbeing. Suicidal behaviour, however, remains understudied in Middle Eastern contexts. This study analysed data from the 2016 Global School-based Student Health Survey collected in the United Arab Emirates (UAE). A sample of 5826 adolescents aged between 11 and 18 years were sampled. Potential risk factors associated with an elevated risk for engagement in suicidal behaviour were examined. These factors were stratified into categories for analysis (demographics, psychosocial, risky health, and socio-environmental). The age-adjusted prevalence of suicidal behaviour amongst the school-going adolescent population in the UAE was 54%. Analyses indicated that elevated risk was significantly associated with anxiety difficulties, the experience of loneliness, and amongst those who smoked tobacco. None of the socio-environmental factors emerged as significant. A dose-dependent relationship was evident in that the degree of risk that was evident appeared to compound as the number of adverse risk factors increased. The data suggest that suicidal behaviour may be highly prevalent in this location. Findings highlight the immense need to develop preventative interventions, some of which may be school-delivered and targeted at parents. Our findings provide initial indications as to which risk factors could be targeted for remediation in developing these interventions.

Adapting a community-based intervention to address social determinants of health influencing pre-exposure prophylaxis services for Black adults in Washington, District of Columbia: A study protocol

Community-based HIV treatment initiation and continuation helps to address social determinants of health (SDOH) barriers to care and increase antiretroviral therapy (ART) uptake and adherence. Similarly, community-based pre-exposure prophylaxis (cbPrEP) services can help address SDOH barriers such as transportation costs and stigma. However, few studies have examined cbPrEP programming in the Washington, District of Columbia (DC) area where more Blacks are disproportionately affected by HIV and have low PrEP uptake. This study aims to adapt and pilot a community-based ART intervention (cbART) intervention for cbPrEP service delivery for Black adults in the Washington, DC area. The adaptation of the cbART intervention will be informed by the ADAPT-ITT framework and the Consolidated Framework for Implementation Research. For Aim 1, in-depth and key informant interviews will be conducted with PrEP program managers at community-based organizations (N = 10), DC health department representatives (N = 8), PrEP providers (N = 10) and current and potential Black PrEP users (n = 24). The interviews will provide an initial assessment of barriers and facilitators to PrEP services and inform the decisions on how to adapt the cbART intervention for cbPrEP services. In Aim 2, we will train and pilot test the cbPrEP intervention for acceptability, feasibility, and appropriateness with Black adults (n = 60). Enrolled participants will complete a survey at baseline and at 45 days post-enrollment. In-depth interviews will be conducted with a subset (N = 16) of participants, those who did not enroll (N = 10) and providers implementing the cbPrEP intervention (N = 8). Alternative strategies to PrEP service delivery are needed to increase PrEP uptake among those most in need in the DC area. If cbPrEP delivery is found to be acceptable, feasible, and appropriate, it could have a significant impact on DC's Ending the HIV Epidemic efforts and will inform future efforts to investigate the intervention's efficacy on PrEP uptake and continuation among Black adults in DC.

HIV Care Profiling and Delivery Status in the Mobile Health Clinics of eThekwini District in KwaZulu Natal, South Africa: A Descriptive Evaluation Study

Mobile health clinics (MHCs) serve as an alternative HIV care delivery method for the HIV-burdened eThekwini district. This study aimed to describe and profile the HIV care services provided by the MHCs through process evaluation. A descriptive cross-sectional quantitative evaluation study was performed on 137 MHCs using total population sampling. An online data collection method using a validated 50-item researcher-developed instrument was administered to professional nurses who are MHC team leaders, following ethical approval from the local university and departments of health. Descriptive statistics were used to analyze the data. The results described that HIV care services are offered in open spaces (43%), community buildings (37%), solid built buildings called health posts (15%), vehicles (9%), and tents (2%) with no electricity (77%), water (55%), and sanitation (64%). Adults (97%) are the main recipients of HIV care in MHCs (90%) offering antiretroviral therapy (95%). Staff, monitoring, and retaining care challenges were noted, with good linkage (91%) and referral pathways (n = 123.90%). In conclusion, the standardization and prioritization of HIV care with specific contextual practice guidelines are vital.

The effect of primary health care on AIDS incidence and mortality: a cohort study of 3.4 million Brazilians

Background

Primary Health Care (PHC) is essential for the health and wellbeing of people living with HIV/AIDS. This study evaluated the effects of one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality.

Methods

A retrospective cohort study carried out in Brazil, from January 1 2007 to December 31 2015. We conducted a quasi-experimental effect evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the effect of FHS on AIDS incidence and mortality and comparing outcomes between residents of municipalities with no FHS coverage with those in municipalities with full FHS coverage. We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated FHS effect by sex and age, and performed a wide range of sensitivity and triangulation analyses.

Findings

FHS coverage was associated with lower AIDS incidence (rate ratio [RR]:0.76, 95%CI:0.68-0.84) and mortality (RR:0.68,95%CI:0.56-0.82). FHS effect was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR 0.62, 95%CI:0.53-0.72) and mortality (RR 0.56, 95%CI:0.43-0.72).

Conclusions

AIDS should be an avoidable outcome for most people living with HIV today, and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

Challenges and Solutions to STI Control in the Era of HIV and STI Prophylaxis

PURPOSE OF REVIEW

This article reviews current efforts to control bacterial sexually transmitted infections (STIs) among HIV pre-exposure prophylaxis (PrEP) users and outlines the opportunities and challenges to controlling STIs within HIV PrEP programs.

RECENT FINDINGS

The incidence of STIs continues to rise globally especially among HIV PrEP users, with an estimated 1 in 4 PrEP users having a curable bacterial STI. STIs and HIV comprise a syndemic needing dual interventions. The majority of STIs are asymptomatic, and when testing is available, many STIs occur in extragenital sites that are missed when relying on urine testing or genital swabs. Optimal testing and treatment, including testing for antimicrobial resistance, pose difficulties in high income countries and is essentially non-existent in most low- and middle-income countries. Novel STI primary prevention strategies, like doxycycline post-exposure prophylaxis (PEP) for STI prevention, have proven to be highly efficacious in some populations. A few jurisdictions have issued normative guidelines and position statements for doxycycline PEP; however, clinical standards for implementation and data on public health impact are limited. STI incidence rates are high and rising in sexually active populations. Sexual health programs should leverage the expansion of HIV PrEP delivery services to integrate STI testing, surveillance, and novel STI prevention services.

Framework for determining the optimal course of action when efficiency and affordability measures differ by perspective in cost-effectiveness analysis-with an illustrative case of HIV treatment in Mozambique

BACKGROUND

Cost-effectiveness analysis (CEA) is a standard tool for evaluating health programs and informing decisions about resource allocation and prioritization. Most CEAs evaluating health interventions in low- and middle-income countries adopt a health sector perspective, accounting for resources funded by international donors and country governments, while often excluding out-of-pocket expenditures and time costs borne by program beneficiaries. Even when patients' costs are included, a companion analysis focused on the patient perspective is rarely performed. We view this as a missed opportunity.

METHODS

We developed methods for assessing intervention affordability and evaluating whether optimal interventions from the health sector perspective also represent efficient and affordable options for patients. We mapped the five different patterns that a comparison of the perspective results can yield into a practical framework, and we provided guidance for researchers and decision-makers on how to use results from multiple perspectives. To illustrate the methodology, we conducted a CEA of six HIV treatment delivery models in Mozambique. We conducted a Monte Carlo microsimulation with probabilistic sensitivity analysis from both patient and health sector perspectives, generating incremental cost-effectiveness ratios for the treatment approaches. We also calculated annualized patient costs for the treatment approaches, comparing the costs with an affordability threshold. We then compared the cost-effectiveness and affordability results from the two perspectives using the framework we developed.

RESULTS

In this case, the two perspectives did not produce a shared optimal approach for HIV treatment at the willingness-to-pay threshold of 0.3 × Mozambique's annual GDP per capita per DALY averted. However, the clinical 6-month antiretroviral drug distribution strategy, which is optimal from the health sector perspective, is efficient and affordable from the patient perspective. All treatment approaches, except clinical 1-month distributions of antiretroviral drugs which were standard before Covid-19, had an annual cost to patients less than the country's annual average for out-of-pocket health expenditures.

CONCLUSION

Including a patient perspective in CEAs and explicitly considering affordability offers decision-makers additional insights either by confirming that the optimal strategy from the health sector perspective is also efficient and affordable from the patient perspective or by identifying incongruencies in value or affordability that could affect patient participation.

Population health impact, cost-effectiveness, and affordability of community-based HIV treatment and monitoring in South Africa: A health economics modelling study

Community-based delivery and monitoring of antiretroviral therapy (ART) for HIV has the potential to increase viral suppression for individual- and population-level health benefits. However, the cost-effectiveness and budget impact are needed for public health policy. We used a mathematical model of HIV transmission in KwaZulu-Natal, South Africa, to estimate population prevalence, incidence, mortality, and disability-adjusted life-years (DALYs) from 2020 to 2060 for two scenarios: 1) standard clinic-based HIV care and 2) five-yearly home testing campaigns with community ART for people not reached by clinic-based care. We parameterised model scenarios using observed community-based ART efficacy. Using a health system perspective, we evaluated incremental cost-effectiveness and net health benefits using a threshold of $750/DALY averted. In a sensitivity analysis, we varied the discount rate; time horizon; costs for clinic and community ART, hospitalisation, and testing; and the proportion of the population receiving community ART. Uncertainty ranges (URs) were estimated across 25 best-fitting parameter sets. By 2060, community ART following home testing averted 27.9% (UR: 24.3-31.5) of incident HIV infections, 27.8% (26.8-28.8) of HIV-related deaths, and 18.7% (17.9-19.7) of DALYs compared to standard of care. Adolescent girls and young women aged 15-24 years experienced the greatest reduction in incident HIV (30.7%, 27.1-34.7). In the first five years (2020-2024), community ART required an additional $44.9 million (35.8-50.1) annually, representing 14.3% (11.4-16.0) of the annual HIV budget. The cost per DALY averted was $102 (85-117) for community ART compared with standard of care. Providing six-monthly refills instead of quarterly refills further increased cost-effectiveness to $78.5 per DALY averted (62.9-92.8). Cost-effectiveness was robust to sensitivity analyses. In a high-prevalence setting, scale-up of decentralised ART dispensing and monitoring can provide large population health benefits and is cost-effective in preventing death and disability due to HIV.

PrEP uptake and early persistence among adolescent girls and young women receiving services via community and hybrid community-clinic models in Namibia

INTRODUCTION

Adolescent girls and young women (AGYW) face barriers in accessing clinic-based HIV pre-exposure prophylaxis (PrEP) services and community-based models are a proposed alternative. Evidence from such models, however, is limited. We evaluated PrEP service coverage, uptake, and early persistence among AGYW receiving services through community and hybrid models in Namibia.

METHODS

We analyzed routine data for AGYW aged 15-24 who initiated PrEP within HIV prevention programming. PrEP was delivered via three models: community-concierge (fully community-based services with individually-tailored refill locations), community-fixed (community-based initiation and refills delivered by community providers on a set schedule at fixed sites), and hybrid community-clinic (community-based initiation and referral to clinics for refills delivered by clinic providers). We examined proportions of AGYW engaged in services along a programmatic PrEP cascade, overall and by model, and assessed factors associated with PrEP uptake and early persistence (refill within 15-44 days after initiation) using multivariable generalized estimating equations.

RESULTS

Over 10-months, 7593 AGYW participated in HIV prevention programming. Of these, 7516 (99.0%) received PrEP education, 6105 (81.2%) received HIV testing services, 6035 (98.9%) tested HIV-negative, and 2225 (36.9%) initiated PrEP. Of the 2047 AGYW expected for PrEP refill during the study period, 254 (12.4%) persisted with PrEP one-month after initiation. Structural and behavioral HIV risk factors including early school dropout, food insecurity, inconsistent condom use, and transactional sex were associated with PrEP uptake. AGYW who delayed starting PrEP were 2.89 times more likely to persist (95% confidence interval (CI): 1.52-5.46) and those receiving services via the community-concierge model were 8.7 times (95% CI: 5.44-13.9) more likely to persist (compared to the hybrid model).

CONCLUSION

Community-based models of PrEP service delivery to AGYW can achieve high PrEP education and HIV testing coverage and moderate PrEP uptake. AGYW-centered approaches to delivering PrEP refills can promote higher persistence.

Preventing tuberculosis with community-based care in an HIV-endemic setting: a modeling analysis

Introduction

Antiretroviral therapy (ART) and TB preventive treatment (TPT) both prevent tuberculosis (TB) disease and deaths among people living with HIV. Differentiated care models, including community-based care, can increase uptake of ART and TPT to prevent TB in settings with a high burden of HIV-associated TB, particularly among men.

Methods

We developed a gender-stratified dynamic model of TB and HIV transmission and disease progression among 100,000 adults ages 15-59 in KwaZulu-Natal, South Africa. We drew model parameters from a community-based ART initiation and resupply trial in sub-Saharan Africa (Delivery Optimization for Antiretroviral Therapy, DO ART) and other scientific literature. We simulated the impacts of community-based ART and TPT care programs during 2018-2027, assuming that community-based ART and TPT care were scaled up to similar levels as in the DO ART trial (i.e., ART coverage increasing from 49% to 82% among men and from 69% to 83% among women) and sustained for ten years. We projected the number of TB cases, deaths, and disability-adjusted life years (DALYs) averted relative to standard, clinic-based care. We calculated program costs and incremental cost-effectiveness ratios from the provider perspective.

Results

If community-based ART care could be implemented with similar effectiveness to the DO ART trial, increased ART coverage could reduce TB incidence by 27.0% (range 21.3% - 34.1%) and TB mortality by 36.0% (range 26.9% - 43.8%) after ten years. Increasing both ART and TPT uptake through community-based ART with TPT care could reduce TB incidence by 29.7% (range 23.9% - 36.0%) and TB mortality by 36.0% (range 26.9% - 43.8%). Community-based ART with TPT care reduced gender disparities in TB mortality rates by reducing TB mortality among men by a projected 39.8% (range 32.2% - 46.3%) and by 30.9% (range 25.3% - 36.5%) among women. Over ten years, the mean cost per DALY averted by community-based ART with TPT care was $846 USD (range $709 - $1,012).

Conclusions

By substantially increasing coverage of ART and TPT, community-based care for people living with HIV could reduce TB incidence and mortality in settings with high burdens of HIV-associated TB and reduce TB gender disparities.

Contribution of community-based organizations in the improvement of Joint United Nations Program on HIV and AIDS 90-90-90: case of the Yaoundé Central Hospital

Community-based organizations (CBOs) are one of the initiatives implemented in Cameroon to improve access to antiretroviral treatment and influence retention in treatment centers. Despite its importance in the decongestion of patients in health facilities, we do not have data to evaluate the overall impact of these organizations. We conducted a two-part observational study. The first part was a descriptive cross-sectional study, where we included patients screened and initiated on anti-retroviral treatment (ART) either by the approved Treatment center (ATC) of Yaoundé Central Hospital (YCH) or by any of our CBOs in 2020. Then, the second part was a retrospective cohort-type study including patients from the 2015 cohort followed up from 2018 to 2020 in order to assess viral load suppression. As regards the first "90", 7,234 screening tests were performed by CBOs in 2020 out of the 28,302 screening tests registered at the YCH, giving a contribution of 25.6%. From the 7,234 screening tests performed by CBOs, 314 people had an HIV-positive result and 230 (73.34%) were linked to ART through CBOs. From the 28,302 screening tests performed at YCH, 1,089 people had an HIV-positive test, and only 354 (32.50%) were linked to ART, giving a significant difference in the link to ART (P-value < 0.00). Concerning the 3rd ''90'', the viral load suppression rates were respectively in CBOs and at YCH of (95.12% vs 90.54%, RR= 0.51; P-value= 0.27 at 12 months); (95.96% vs 95.34%, relative risk (RR)= 0.85; P-value= 0.81 at 24 months); and (96.91% vs 94.15%, RR= 0.52; P-value = 0.24 at 36 months). In conclusion, we say that the follow-up of patients living with HIV in the community does not negatively affect the evolution of the disease as one might think.

Thetha Nami ngithethe nawe (Let's Talk): a stepped-wedge cluster randomised trial of social mobilisation by peer navigators into community-based sexual health and HIV care, including pre-exposure prophylaxis (PrEP), to reduce sexually transmissible HIV amongst young people in rural KwaZulu-Natal, South Africa

BACKGROUND

Antiretroviral therapy (ART) through universal test and treat (UTT) and HIV pre-exposure prophylaxis (PrEP) substantially reduces HIV-related mortality and incidence. Effective ART based prevention has not translated into population-level impact in southern Africa due to sub-optimal coverage among youth. We aim to investigate the effectiveness, implementation and cost effectiveness of peer-led social mobilisation into decentralised integrated HIV and sexual reproductive health (SRH) services amongst adolescents and young adults in KwaZulu-Natal (KZN).

METHODS

We are conducting a type 1a hybrid effectiveness/implementation study, with a cluster randomized stepped-wedge trial (SWT) to assess effectiveness and a realist process evaluation to assess implementation outcomes. The SWT will be conducted in 40 clusters in rural KZN over 45 months. Clusters will be randomly allocated to receive the intervention in period 1 (early) or period 2 (delayed). 1) Intervention arm: Resident peer navigators in each cluster will approach young men and women aged 15-30 years living in their cluster to conduct health, social and educational needs assessment and tailor psychosocial support and health promotion, peer mentorship, and facilitate referrals into nurse led mobile clinics that visit each cluster regularly to deliver integrated SRH and differentiated HIV prevention (HIV testing, UTT for those positive, and PrEP for those eligible and negative). Standard of Care is UTT and PrEP delivered to 15-30 year olds from control clusters through primary health clinics. There are 3 co-primary outcomes measured amongst cross sectional surveys of 15-30 year olds: 1) effectiveness of the intervention in reducing the prevalence of sexually transmissible HIV; 2) uptake of universal risk informed HIV prevention intervention; 3) cost of transmissible HIV infection averted. We will use a realist process evaluation to interrogate the extent to which the intervention components support demand, uptake, and retention in risk-differentiated biomedical HIV prevention.

DISCUSSION

The findings of this trial will be used by policy makers to optimize delivery of universal differentiated HIV prevention, including HIV pre-exposure prophylaxis through peer-led mobilisation into community-based integrated adolescent and youth friendly HIV and sexual and reproductive health care.

Effect of index HIV self-testing for sexual partners of clients enrolled in antiretroviral therapy (ART) programs in Malawi: A randomized controlled trial

BACKGROUND

HIV testing among the sexual partners of HIV-positive clients is critical for case identification and reduced transmission in southern and eastern Africa. HIV self-testing (HIVST) may improve uptake of HIV services among sexual partners of antiretroviral therapy (ART) clients, but the impact of HIVST on partner testing and subsequent ART initiation remains unclear.

METHODS AND FINDINGS

We conducted an individually randomized, unblinded trial to assess if an index HIVST intervention targeting the partners of ART clients improves uptake of testing and treatment services in Malawi. The trial was conducted at 3 high-burden facilities in central and southern Malawi. ART clients attending HIV treatment clinics were randomized using simple randomization 1:2·5 to: (1) standard partner referral slip (PRS) whereby ART clients were given facility referral slips to distribute to their primary sexual partners; or (2) index HIVST whereby ART clients were given HIVST kits + HIVST instructions and facility referral slips to distribute to their primary sexual partners. Inclusion criteria for ART clients were: ≥15 years of age, primary partner with unknown HIV status, no history of interpersonal violence (IPV) with partner, and partner lives in facility catchment area. The primary outcome was partner testing 4-weeks after enrollment, reported by ART clients using endline surveys. Medical chart reviews and tracing activities with partners with a reactive HIV test measured ART initiation at 12 months. Analyses were conducted based on modified intention-to-treat principles, whereby we excluded individuals who did not have complete endline data (i.e., were loss to follow up from the study). Adjusted models controlled for the effects of age and marital status. A total of 4,237 ART clients were screened and 484 were eligible and enrolled (77% female) between March 28, 2018 and January 5, 2020. A total of 365 participants completed an endline survey (257/34 index HIVST arm; 107/13 PRS arm) and were included in the final analysis (78% female). Testing coverage among sexual partners was 71% (183/257) in the index HIVST arm and 25% (27/107) in the PRS arm (aRR: 2·77, 95% CI [2·56 to 3·00], p ≤ 0.001). Reported HIV positivity rates did not significantly differ by arm (16% (30/183) in HIVST versus 15% (4/27) in PRS; p = 0.99). ART initiation at 12 months was 47% (14/30) in HIVST versus 75% (3/4) in PRS arms; however, index HIVST still resulted in a 94% increase in the proportion of all partners initiating ART due to higher HIV testing rates in the HIVST arm (5% partners initiated ART in HVIST versus 3% in PRS). Adverse events including IPV and termination of the relationship did not vary by arm (IPV: 3/257 index HIVST versus 4/10 PRS; p = 0.57). Limitations include reliance on secondary report by ART clients, potential social desirability bias, and not powered for sex disaggregated analyses.

CONCLUSIONS

Index HIVST significantly increased HIV testing and the absolute number of partners initiating ART in Malawi, without increased risk of adverse events. Additional research is needed to improve linkage to HIV treatment services after HIVST use.

Study protocol: the ILANA study - exploring optimal implementation strategies for long-acting antiretroviral therapy to ensure equity in clinical care and policy for women, racially minoritised people and older people living with HIV in the UK - a qualitative multiphase longitudinal study design

INTRODUCTION

Cabotegravir and rilpivirine (CAB+RPV long-acting (LA)) is recommended as a treatment for HIV-1 allowing people living with HIV to receive 2 monthly injectable treatment, rather than daily pills. Providing injectable therapy in a system designed to provide and manage study participants on oral treatments poses logistical challenges namely how resources are used to accommodate patient preference within constrained health economies with capacity limitations. In this pragmatic multicentre study, we aim to understand the implementation of CAB-RPV-LA administration in two settings via mixed methods to explore perspectives of participants and the clinical team delivering CAB+RPV LA.

METHODS AND ANALYSIS

Women, racially minoritised people and older people are chronically under-represented in HIV clinical trials so the ILANA trial has set recruitment caps to ensure recruitment of 50% women, 50% ethnically diverse people and 30% over 50 years of age to include a more representative study population. Using a mixed-methods approach, the primary objective is to identify and evaluate the critical implementation strategies for CAB+RPV LA in both hospital and community settings. Secondary objectives include evaluating feasibility and acceptability of CAB+RPV LA administration at UK clinics and community settings from the perspective of HIV care providers, nurses and representatives at community sites, evaluating barriers to implementation, the utility of implementation strategies and adherence.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Health Research Authority Research Ethics Committee (REC reference: 22/PR/0318). The dissemination strategy has been formulated with the SHARE Collaborative Community Advisory Board to maximise the impact of this work on clinical care and policy. This strategy draws on and leverages existing resources within the participating organisations, such as their academic infrastructure, professional relationships and community networks. The strategy will leverage the Public Engagement Team and press office to support dissemination of findings.

Cost of improved test and treat strategies in Indonesia

OBJECTIVE

To estimate and compare the cost of improved test and treat strategies in Indonesia under HIV Awal (Early) Testing and Treatment Indonesia (HATI) implementation trial in community-based and hospital-based clinics.

DESIGN

The cost and outcome [i.e. CD4 + cell count] and viral load (VL) at the beginning of interventions and their change overtime) analysis of Simplifying ART Initiation (SAI), Community-based Organization and community-based ART Service (CBO), Motivational Interviewing (MI), Oral Fluid-based Testing (OFT), and Short Message Service (SMS) reminder in community-based and hospital-based clinics in 2018-2019.

METHOD

We estimated the total and unit costs per patient (under HATI implementation trial interventions) per year from societal perspective in various settings, including costs from patients' perspective for SAI and MI. We also analyzed the outcome variables (i.e. CD4 + cell count and VL at the beginning of each intervention, the change in CD4 + cell count and VL over time, and adherence rate).

RESULT

The unit cost per patient per year of SAI and SMS were lower at the community-based clinics, and more patients visited community-based clinics. The cost per patient visit from patient perspective for SAI and MI was mostly lower than 10% of the patients' household monthly expenditure. Average CD4 + cell count was higher and average VL was lower at the start of interventions at the community-based clinics, while average CD4 + cell count and VL changes and adherence rate were similar between the two types of clinics.

CONCLUSION

Community-based clinics hold the potential for scaling up the interventions as it costs less from societal perspective and showed better outcome improvement during the HATI implementation trial.

CROI 2023: Tuberculosis and Infectious Complications in Persons With HIV

Novel implementation strategies to increase uptake and adherence to tuberculosis (TB) preventive therapy hold promise for reducing TB incidence in persons with HIV in high-burden settings. In persons who develop drug-susceptible TB, progress to shorten TB treatment continues to be made with the introduction of new drugs and novel treatment strategies that could allow for treatment shortening to 2 months for most people. A global case series provided powerful evidence that mpox should be considered an HIV-related opportunistic infection given its severe manifestations and poor outcomes. Studies of TB and infectious complications in people with HIV presented at the 2023 Conference on Retroviruses and Opportunistic Infections (CROI) are summarized herein.

Strategies to improve antiretroviral therapy (ART) initiation and early engagement among men in sub-Saharan Africa: A scoping review of interventions in the era of universal treatment

OBJECTIVES

Men in sub-Saharan Africa (SSA) have lower rates of antiretroviral therapy (ART) initiation and higher rates of early default than women. Little is known about effective interventions to improve men's outcomes. We conducted a scoping review of interventions aimed to increase ART initiation and/or early retention among men in SSA since universal treatment policies were implemented.

METHODS

Three databases, HIV conference databases and grey literature were searched for studies published between January 2016 to May 2021 that reported on initiation and/or early retention among men. Eligibility criteria included: participants in SSA, data collected after universal treatment policies were implemented (2016-2021), quantitative data on ART initiation and/or early retention for males, general male population (not exclusively focused on key populations), intervention study (report outcomes for at least one non-standard service delivery strategy), and written in English.

RESULTS

Of the 4351 sources retrieved, 15 (reporting on 16 interventions) met inclusion criteria. Of the 16 interventions, only two (2/16, 13%) exclusively focused on men. Five (5/16, 31%) were randomised control trials (RCT), one (1/16, 6%) was a retrospective cohort study, and 10 (10/16, 63%) did not have comparison groups. Thirteen (13/16, 81%) interventions measured ART initiation and six (6/16, 37%) measured early retention. Outcome definitions and time frames varied greatly, with seven (7/16, 44%) not specifying time frames at all. Five types of interventions were represented: optimising ART services at health facilities, community-based ART services, outreach support (such as reminders and facility escort), counselling and/or peer support, and conditional incentives. Across all intervention types, ART initiation rates ranged from 27% to 97% and early retention from 47% to 95%.

CONCLUSIONS

Despite years of data of men's suboptimal ART outcomes, there is little high-quality evidence on interventions to increase men's ART initiation or early retention in SSA. Additional randomised or quasi-experimental studies are urgently needed.

"That was our afterparty": a qualitative study of mobile, venue-based PrEP for MSM

BACKGROUND

HIV preexposure prophylaxis (PrEP) uptake among men who have sex with men (MSM), a group disproportionately impacted by HIV, is not commensurate with need. Settings which reduce or remove barriers to accessing care are promising venues to support PrEP uptake. PrEP provision at mobile clinics represents a novel strategy to increase PrEP access; however, the acceptability and feasibility of this approach have not been well studied.

METHODS

Our objective was to understand patient and staff experiences of a mobile clinic van offering PrEP and sexual health services in Boston, Massachusetts, USA. We interviewed mobile unit users and conducted focus groups with mobile unit staff and users. Data were organized using Dedoose software, and content analysis was used to identify themes of access, community, and stigma.

RESULTS

Nineteen individuals (16 patients and 3 staff members) participated in interviews (N = 13) or focus groups (N = 6). All patients identified as MSM, 63% were Hispanic or Latino, and 21% of patient interviews were conducted in Spanish. Logistical and psychological convenience facilitated service use, while the community-oriented environment improved satisfaction with care. Overall, participants supported expansion of mobile unit services and recommended changes to improve access to longitudinal care. However, some barriers to PrEP persisted, including low HIV risk perception and stigma about sexual behavior.

CONCLUSIONS

Mobile units can promote sexual health and PrEP uptake, particularly for populations facing social and logistical barriers to care in traditional settings.

Mobility and HIV care engagement: a research agenda

INTRODUCTION

Mobility is common and an essential livelihood strategy in sub-Saharan Africa (SSA). Mobile people suffer worse outcomes at every stage of the HIV care cascade compared to non-mobile populations. Definitions of mobility vary widely, and research on the role of temporary mobility (as opposed to permanent migration) in HIV treatment outcomes is often lacking. In this article, we review the current landscape of mobility and HIV care research to identify what is already known, gaps in the literature, and recommendations for future research.

DISCUSSION

Mobility in SSA is closely linked to income generation, though caregiving, climate change and violence also contribute to the need to move. Mobility is likely to increase in the coming decades, both due to permanent migration and increased temporary mobility, which is likely much more common. We outline three central questions regarding mobility and HIV treatment outcomes in SSA. First, it is unclear what aspects of mobility matter most for HIV care outcomes and if high-risk mobility can be identified or predicted, which is necessary to facilitate targeted interventions for mobile populations. Second, it is unclear what groups are most vulnerable to mobility-associated treatment interruption and other adverse outcomes. And third, it is unclear what interventions can improve HIV treatment outcomes for mobile populations.

CONCLUSIONS

Mobility is essential for people living with HIV in SSA. HIV treatment programmes and broader health systems must understand and adapt to human mobility, both to promote the rights and welfare of mobile people and to end the HIV pandemic.

Engaging men through HIV self-testing with differentiated care to improve ART initiation and viral suppression among men in Malawi (ENGAGE): A study protocol for a randomized control trial

BACKGROUND

Men experience twice the mortality of women while on ART in sub-Saharan Africa (SSA) largely due to late HIV diagnosis and poor retention. Here we propose to conduct an individually randomized control trial (RCT) to investigate the impact of three-month home-based ART (hbART) on viral suppression among men who were not engaged in care.

METHODS AND DESIGN

A programmatic, individually randomized non-blinded, non-inferiority-controlled trial design (ClinicalTrials.org NCT04858243). Through medical chart reviews we will identify "non-engaged" men living with HIV, ≥15years of age who are not currently engaged in ART care, including (1) men who have tested HIV-positive and have not initiated ART within 7 days; (2) men who have initiated ART but are at risk of immediate default; and (3) men who have defaulted from ART. With 1:1 computer block randomization to either hbART or facility-based ART (fbART) arms, we will recruit men from 10-15 high-burden health facilities in central and southern Malawi. The hbART intervention will consist of 3 home-visits in a 3-month period by a certified male study nurse ART provider. In the fbART arm, male participants will be offered counselling at male participant's home, or a nearby location that is preferred by participants, followed with an escort to the local health facility and facility navigation. The primary outcome is the proportion of men who are virally suppressed at 6-months after ART initiation. Assuming primary outcome achievement of 24.0% and 33.6% in the two arms, 350 men per arm will provide 80% power to detect the stated difference.

DISCUSSION

Identifying effective ART strategies that are convenient and accessible for men in SSA is a priority in the HIV world. Men may not (re-)engage in facility-based care due to a myriad of barriers. Two previous trials investigated the impact of hbART on viral suppression in the general population whereas this trial focuses on men. Additionally, this trial involves a longer duration of hbART i.e., three months compared to two weeks allowing men more time to overcome the initial psychological denial of taking ART.

HIV Treatment and Care of Adolescents: Perspectives of Adolescents on Community-Based Models in Northern Uganda

Background

Differentiated service delivery models for people living with HIV continue to be scaled up to expand access to HIV services and treatment continuity. However, there is a gap in information on adolescents' perspectives on community-based models. We aimed to explore the perspectives of adolescents living with HIV on community-based models in northern Uganda.

Materials and Methods

Between February and March 2022, we conducted a descriptive qualitative study at two health centres IV in Northern Uganda. Data was collected using an interview guide. The study had 25 purposively selected adolescents enrolled in community-based models for HIV care and treatment. The interviews were audio-recorded, transcribed verbatim, and translated. We analyzed data using a thematic approach.

Results

A total of 25 in-depth interviews with HIV-positive adolescents were conducted. More than half (52.0%) of the participants were females, 84.0% were not married, and 44.0% had no formal education. The mean age of the respondents was 15.6 (±1.9) years. The major themes were: community-based models currently accessed by adolescents, benefits, and challenges of the models. Although there are other community-based models (community pharmacies, home ART deliveries) our exploration only discovered two models used by these adolescents to access care, namely, Community Drug Distribution Point (CDDP) and Community Client-Led ART Delivery Groups (CCLADs). The benefits included reduced transportation costs, convenient service access, ART adherence, peer support, a comfortable environment and less stress. However, our results indicate that these models had some challenges, including lack of confidentiality and privacy, perceived stigma, and a lack of face-to-face interaction.

Conclusion

Our findings show that CDDP and CCLADs are the two CBMs used by adolescents in Lira District to access treatment and care. Adolescents benefited from these models through reduced transport costs, the convenience of accessing HIV care and treatment, and social support. The challenges associated with these models are lack of confidentiality and privacy, perceived stigma, and a lack of face-to-face interaction. The Ministry of Health should work with other implementing partners to strengthen the implementation of these models to improve HIV/AIDS service delivery for adolescents.

Linkage to HIV Care Following HIV Self-testing Among Men: Systematic Review of Quantitative and Qualitative Studies from Six Countries in Sub-Saharan Africa

Gender disparities are pervasive throughout the HIV care continuum in sub-Saharan Africa, with men testing, receiving treatment, and achieving viral suppression at lower rates, and experiencing mortality at higher rates, compared with women. HIV self-testing (HIVST) has been shown to be highly acceptable among men in sub-Saharan Africa. However, evidence on linkage to HIV care following a reactive HIVST result is limited. In this systematic review, we aimed to synthesize the quantitative and qualitative literature from sub-Saharan Africa on men's rates of linkage to HIV care after receiving a reactive HIVST result. We systematically searched 14 bibliometric databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) flow diagram was used to document the screening results. The Mixed Methods Appraisal Tool (MMAT) was used to assess the methodological quality of the included studies. Of 22,446 references screened, 15 articles were eligible for inclusion in this review. Linkage to HIV care following a reactive HIVST result was subject to several barriers: financial constraints due to travelling costs, potential long waiting hours at the clinics, stigma, discrimination, and privacy concerns. Men's rates of seeking confirmatory testing and linking to HIV care following a reactive HIVST result were inconsistent across studies. Combining financial incentives with HIVST was found to increase the likelihood of linking to HIV care following a reactive HIVST result. The variable rates of linkage to HIV care following a reactive HIVST result suggest a need for further research and development into strategies to increase linkage to HIV care.

Review of antiretroviral therapy coverage in 10 highest burden HIV countries in Africa: 2015-2020

Africa is responsible for two-thirds of the global total of new HIV infections. South Africa, Nigeria, Mozambique, Uganda, Tanzania, Zambia, Zimbabwe, Kenya, Malawi, and Ethiopia were responsible for 80% of HIV cases in Africa in 2014 according to the Joint United Nations Programme on HIV/AIDS (UNAIDS). This study assesses antiretroviral coverage strategies implemented by these countries after the initiation of the "Fast-Track strategy to end the AIDS epidemic by 2030." Data reported in this review were obtained from different e-bibliographic including PubMed, Google Scholar, and Research Gate. Key terms were "Antiretroviral therapy," "Antiretroviral treatment," "HIV treatment," "HIV medication," "HIV/AIDS therapy," "HIV/AIDS treatment" + each of the countries listed earlier. We also extracted data on antiretroviral therapy (ART) coverage from the UNAIDS database. About 50 papers published from 2015 to 2021 met the inclusion criteria. All 10 countries have experienced an increase in ART coverage from 2015 to 2020 with an average of 47.6% increment. Nigeria recorded the highest increase in the rate of ART coverage (72% increase) while Ethiopia had the least (30%). New strategies adopted to increase ART coverage and retention in most countries were community-based models and the use of mobile health technology rather than clinic-based. These strategies focus on promoting task shifting, door-to-door access to HIV services, and a long-term supply of antiretroviral medications. Most of these strategies are still in the piloting stage. However, some new strategies and frameworks have been adopted nationwide in countries like Mozambique, Tanzania, Zambia, Zimbabwe, Kenya, and Malawi. Identified challenges include lack of funding, inadequate testing and surveillance services, poor digital penetration, and cultural/religious beliefs. The adoption of community-based and digital health strategies could have contributed to increased ART coverage and retention. African countries should facilitate nationwide scaling of ART coverage strategies to attain the 95-95-95 goal by 2030.

Improving HIV pre-exposure prophylaxis persistence among adolescent girls and young women: Insights from a mixed-methods evaluation of community, hybrid, and facility service delivery models in Namibia

Introduction

Despite the potential for community-based approaches to increase access to pre-exposure prophylaxis (PrEP) for adolescent girls and young women (AGYW), there is limited evidence of whether and how they improve PrEP persistence. We compared PrEP persistence among AGYW receiving services through community and hybrid models in Namibia to facility-based services. We subsequently identify potential mechanisms to explain how and why community and hybrid models achieved (or not) improved persistence to inform further service delivery innovation.

Methods

Data were collected from PrEP service delivery to AGYW over two-years in Namibia's Khomas Region. We used Kaplan-Meier analysis to estimate survival curves for PrEP persistence beyond three-months after initiation and report the cumulative probability of persistence at one- and three-months. Persistence was defined as any PrEP use within three months after initiation followed by a PrEP refill or previously prescribed supply of at least 30 days at the three-month visit. Interviews were conducted with 28 AGYW and 19 providers and analyzed using a deductive-inductive thematic approach.

Results

From October 2017 through September 2019, 372 (18.7%) AGYW received services through a facility model, 302 (15.1%) through a community model, and 1,320 (66.2%) through a hybrid model. PrEP persistence at one- and three-months was 41.2% and 34.9% in the community model and 6.2% and 4.8% in the hybrid model compared to 36.8% and 26.7% in the facility model. Within the community and hybrid models, we identified three potential mechanisms related to PrEP persistence. Individualized service delivery offered convenience and simplicity which enabled AGYW to overcome barriers to obtaining refills but did not work as well for highly mobile AGYW. Consistent interactions and shared experiences fostered social connectedness with providers and with peers, building social networks and support systems for PrEP use. PrEP and HIV-related stigma, however, was widely experienced outside of these networks. Community-to-facility referral for PrEP refill triggered apprehension towards unfamiliar PrEP services and providers in AGYW, which discouraged persistence.

Conclusion

Service delivery approaches that offer convenience and simplicity and foster social connectedness may reduce access barriers and increase social support enabling AGYW to self-manage their PrEP use and achieve improved PrEP persistence.

Fee for home delivery and monitoring of antiretroviral therapy for HIV infection compared with standard clinic-based services in South Africa: a randomised controlled trial

BACKGROUND

Home delivery and monitoring of antiretroviral therapy (ART) is convenient, overcomes logistical barriers, and could increase individual ART adherence and viral suppression. With client payment and sufficient health benefits, this strategy could be scalable. The aim of the Deliver Health Study was to test the acceptability and efficacy of a user fee for home ART monitoring and delivery.

METHODS

We conducted a randomised trial, the Deliver Health Study, of a fee for home delivery of ART compared with free clinic ART delivery in South Africa. People with HIV who were 18 years or older and clinically stable (including CD4 count >100 cells per μL and WHO HIV stage 1-3) were randomly assigned to: (1) fee for home delivery and monitoring of ART, including community ART initiation if needed; or (2) clinic-based ART (standard of care). The one-time fee for home delivery (ZAR 30, 60, and 90; equivalent to US$2, 4, 6) was tiered on the basis of participant income. The primary outcomes were recorded fee payment and acceptability assessed via questionnaire. The key virological secondary outcome was viral suppression with the difference between study groups assessed through robust Poisson regression including participants with viral load measured at exit (modified intention-to-treat analysis). This trial is registered on ClinicalTrials.gov (NCT04027153) and is complete, with analyses ongoing.

FINDINGS

From Oct 7, 2019, to Jan 30, 2020, 162 participants were enrolled; 82 were randomly assigned to the fee for home delivery group and 80 to the clinic-based group, with similar characteristics at baseline. Overall, 87 (54%) participants were men, 101 (62%) were on ART, and 98 (60%) were unemployed. In the home delivery group, 40 (49%), 33 (40%), and nine (11%) participants qualified for the ZAR 30, 60, and 90 fee, respectively. Median follow-up was 47 weeks (IQR 43-50) with 96% retention. 80 (98%) participants paid the user fee, with high acceptability and willingness to pay. In the modified intention-to-treat analysis of 155 (96%) participants who completed follow-up, fee for home delivery and monitoring statistically significantly increased viral suppression from 74% to 88% overall (RR 1·21, 95% CI 1·02-1·42); and from 64% to 84% among men (1·31, 1·01-1·71).

INTERPRETATION

Among South African adults with HIV, a fee for home delivery and monitoring of ART significantly increased viral suppression compared with clinic-based ART. Clients' paying a fee for home delivery and monitoring of ART was highly acceptable in the context of low income and high unemployment, and improved health outcomes as a result. Home ART delivery and monitoring, potentially with a user fee to offset costs, should be evaluated as a differentiated service delivery strategy to increase access to care.

Experiences and Perceptions on Community Client-Led ART Delivery (CCLADS) Model of Antiretroviral (ART) Delivery: Patients' and Providers' Perspectives in South Western Uganda

Purpose

Community Client-Led ART Delivery groups (CCLADS) were introduced as part of the differentiated service delivery models in 2017 to better serve growing number of HIV patients and reduce unnecessary burden on the HIV care delivery system. However, there is limited evidence on the exact patients' and care providers' experiences and perceptions regarding the CCLADS model of ART delivery. We therefore aimed to explore the experiences and perceptions on CCLADS model from the patient and provider perspectives.

Participants and Methods

A descriptive qualitative study was conducted at two ART clinics in Southwestern Uganda. We conducted in-depth interviews (IDI) to get a deeper understanding of the patient and providers' perspective regarding the model. Responses from participants were recorded using audio recorders and were translated and transcribed. We used thematic approach to analyze the data.

Results

A total of 20 in depth interviews were conducted, with providers, CCLAD leaders and Adults Living with HIV (ALHIV) to assess the experiences and perceptions to participation among People Living with HIV (PLHIV) enrolled in CCLADS and the care providers. Key themes included benefits, limitations, experiences and perceptions of CCLADS. Benefits to ALHIV included: Longer refills, reduced transport costs, receive drugs in time, peer advice; to providers: time saving, less tiresome and reduced congestion at facility. Barriers included: stigma, limited outreaches, failure to comply. Patients perceived the model positively (cost effective, improved quality care, no missed appointment where as others were negative (blood samples not taken like before). Experiences also included enough time, learnt some activities and good adherence.

Conclusion

Participation in the CCLADS groups provides several benefits to the patient including reduced transport, longer refills and good adherence. Stigma remains a challenge to CCLADS participation, which requires innovative and collaborative strategies from Ministry of Health (MOH) and implementation partners to address in order to sustain CCLADS participation.

Adolescent retention in HIV care within differentiated service-delivery models in sub-Saharan Africa

Adolescents and young people living with HIV are at risk of disengaging from HIV care at all stages of the care cascade. Differentiated models of care offer simplified HIV-service delivery options in the hope of improving treatment outcomes, including retention on antiretroviral therapy. However, it remains unclear how successful and widespread these models are for adolescents in sub-Saharan Africa, where the burden of HIV is the greatest. Very few differentiated models of care specifically targeted to adolescents can be found and this priority group are currently ineligible from several models that exist. Where differentiated care has been made available to adolescents, data on the implementation and effectiveness of these interventions remain scarce. Despite this scarcity of evidence on the effectiveness of differentiated care among adolescent populations, several interventions, particularly community-based groups with peer navigators or supporters, might have potential to increase the reach, effectiveness, and adoption of differentiated care in adolescent HIV-care programmes.

"That makes me feel human": a qualitative evaluation of the acceptability of an HIV differentiated care intervention for formerly incarcerated people re-entering community settings in South Africa

BACKGROUND

Correctional settings in South Africa have disproportionately high rates of HIV infection; a large number of inmates living with HIV return to the community each year. The transition community adherence club (TCAC) intervention was a differentiated care delivery approach with structural and peer components designed to increase antiretroviral therapy (ART) adherence and HIV care engagement following release from incarceration. The objective of this study was to assess the acceptability of the TCAC intervention among HIV-infected community re-entrants to inform program revisions and future intervention designs.

METHODS

This was a qualitative study set within a randomized controlled trial (RCT) of the TCAC intervention in South Africa. We conducted semi-structured, in-depth interviews with 16 re-entrants living with HIV and assigned to the intervention arm. All interviews were audio-recorded, transcribed, translated, and de-identified. Transcripts were coded and analyzed using content analysis, and acceptability was assessed using the Theoretical Framework of Acceptability (TFA).

RESULTS

Overall, study participants reported that the TCAC intervention was acceptable. Development of supportive relationships between participants, non-judgmental attitudes from peer-facilitators, and perceived effectiveness of the intervention to support ART adherence and HIV care were noted as the most valued components. An altruistic desire to help other participants facing similar post-incarceration and HIV-related challenges was a key motivator for TCAC attendance. A lack of access to reliable transportation to intervention sites and clinic-based medication collection were described as burdens to program participation. Illicit drug use by other group members and negative social influences were also identified as potential barriers to optimal program engagement.

CONCLUSION

The TCAC was a well-accepted model of differentiated care delivery among re-entrants living with HIV in South Africa. To further enhance intervention acceptability for future scale-ups, program revisions should address logistical barriers related to reaching TCAC sites and implementing ART distribution at TCAC group sessions.
