Test but not treat: Community members' experiences with barriers and facilitators to universal antiretroviral therapy uptake in rural KwaZulu-Natal, South Africa

Ending AIDS as a public health threat: the imperative for clear messaging on U=U, viral suppression, and zero risk

To end AIDS as a public health threat by 2030, we must leverage both the impactful message of U=U (undetectable equals untransmittable) and viral suppression to improve the wellbeing of individuals living with HIV, increase engagement with HIV services, and reduce barriers such as stigma, discrimination, and criminalisation. This message requires clear and unambiguous evidence-based narratives that emphasise the message that there is zero risk of sexual transmission when an undetectable viral load is maintained and negligible risk when viral suppression (as defined by 200-1000 copies per mL) is maintained. Dissemination of this information to individuals living with or affected by HIV, health-care workers, communities, the general public, and policy makers will increase awareness and credibility of this message and challenge deep-seated misperceptions. Furthermore, understanding the impact of this evidence underscores the necessity to urgently prioritise universal access to quality care, including viral load testing; leverage community leadership to address structural barriers; and monitor for ongoing success. Responsible and equitable messaging, which includes attention to women and marginalised groups, should be used to realise benefits for personal wellbeing and work towards an AIDS-free future.

Factors associated with COVID-19 vaccine uptake among South African health care workers

BACKGROUND

Identifying factors associated with vaccine uptake among health care workers (HCWs) remains crucial to generating evidence aimed at guiding national COVID-19 vaccination and future infectious disease outbreak strategies. This study aimed to elucidate these factors, focusing on the interplay between socio-demographic, health, knowledge, beliefs and attitudinal indicators.

METHODS

This was a cross-sectional online survey administered to HCWs across South Africa between August and October 2022. Bivariate and Multivariate logistic regressions identified associations between COVID-19 vaccine uptake and demographics, occupational characteristics, general knowledge of and attitudes towards vaccination, perceived COVID-19 risk and perceived importance of COVID-19 vaccine attributes.

RESULTS

Analysis revealed high vaccine uptake rates among the sample of 5564 HCWs, with 87.6% of the sample vaccinated at the time of the study. Demographic measures significantly associated with vaccine uptake were age (P-value = 0.001), race (P-value = 0.021), religion (P-value = 0.004), and having a chronic illness (P-value <0.001). Belief and attitude measures significantly associated with vaccine uptake included: need for vaccines (P-value <0.001), perceived risk of infection (P-value = 0.001), perceived patient risk (P-value <0.001), and perceived vaccine knowledge (P-value <0.001). Multivariate analysis revealed that HCWs who listed their religion as African Spirituality (OR = 0.4; 95% CI = 0.2-0.7; P-value = 0.002) and had any occupation other than nurse or doctor (OR = 0.6; 95% CI = 0.4-0.8; P-value <0.001), were less likely to vaccinate, while HCWs who had a chronic condition (OR = 1.5; 95% CI = 1.2-2.0; P-value <0.001) were more likely to have been vaccinated.

CONCLUSION

This study provides useful insights into the factors associated with and possibly driving COVID-19 vaccine uptake among HCWs in South Africa. These results add to a limited body of knowledge on contextual dynamics associated with vaccination programmes in Africa.

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.

Interventions to improve young men's utilisation of HIV-testing services in KwaZulu-Natal, South Africa: perspectives of young men and health care providers

Introduction: HIV-testing services (HTS) are an important point of entry to prevention and treatment of HIV in South Africa. Despite the availability of HTS across the region and in SA, the uptake among men remains low, especially young men residing in rural and peri-urban communities. This study aimed to explore interventions that could improve the uptake of HTS among young men in KwaZulu-Natal.Methods: A descriptive exploratory qualitative study was conducted in which 17 young men and two health care providers in Ladysmith were purposively and conveniently sampled. Data were collected through semi-structured interviews using WhatsApp and landline audio calls between September and December 2021 and thematically analysed.Results: An improvement in the health care provider attitudes and service delivery, establishment of adherence clubs for young people living with HIV, ensuring a diverse and balanced health care provider staff composition at primary health care facilities, and increased demand creation in spaces frequented by men are vital for enhancing access and utilisation of HTS among young men. Additionally, health care providers believe that the presence of male health care providers, investment in health education, prioritising men in the morning at the primary health care facilities, and the establishment of male clinics within communities as key factors in improving the uptake of HTS among young men.Conclusion: To attract and retain young men in HTS and in HIV treatment and care, several improvements at primary health care facilities need to be implemented. These should focus on addressing the specific needs and preferences of young men, ensuring their comfort and engagement in health care.

Experiences of stigma and HIV care engagement in the context of Treat All in Rwanda: a qualitative study

BACKGROUND

'Treat All' policies recommending immediate antiretroviral therapy (ART) soon after HIV diagnosis for all people living with HIV (PLHIV) are now ubiquitous in sub-Saharan Africa. While early ART initiation and retention is effective at curtailing disease progression and transmission, evidence suggests that stigma may act as a barrier to engagement in care. This study sought to understand the relationships between HIV stigma and engagement in care for PLHIV in Rwanda in the context of Treat All.

METHODS

Between September 2018 and March 2019, we conducted semi-structured, qualitative interviews with adult PLHIV receiving care at two health centers in Kigali, Rwanda. We used a grounded theory approach to data analysis to develop conceptual framework describing how stigma influences HIV care engagement in the context of early Treat All policy implementation in Rwanda.

RESULTS

Among 37 participants, 27 (73%) were women and the median age was 31 years. Participants described how care engagement under Treat All, including taking medications and attending appointments, increased their visibility as PLHIV. This served to normalize HIV and use of ART but also led to high levels of anticipated stigma in the health center and community at early stages of treatment. Enacted stigma from family and community members and resultant internalized stigma acted as additional barriers to care engagement. Nonetheless, participants described how psychosocial support from care providers and family members helped them cope with stigma and promoted continued engagement in care.

CONCLUSIONS

Treat All policy in Rwanda has heightened the visibility of HIV at the individual and social levels, which has influenced HIV stigma, normalization, psychosocial support and care engagement in complex ways. Leveraging the individual and community support described by PLHIV to deliver evidence-based, peer or provider-delivered stigma reduction interventions may aid in attaining Treat All goals.

Implementation and effectiveness of a linkage to HIV care intervention in rural South Africa (ANRS 12249 TasP trial)

BACKGROUND

Timely linkage to care and ART initiation is critical to decrease the risks of HIV-related morbidity, mortality and HIV transmission, but is often challenging. We report on the implementation and effectiveness of a linkage-to-care intervention in rural KwaZulu-Natal, South Africa.

METHODS

In the ANRS 12249 TasP trial on Universal Testing and Treatment (UTT) implemented between 2012-2016, resident individuals ≥16 years were offered home-based HIV testing every six months. Those ascertained to be HIV-positive were referred to trial clinics. Starting May 2013, a linkage-to-care intervention was implemented in both trial arms, consisting of tracking through phone calls and/or home visits to "re-refer" people who had not linked to care to trial clinics within three months of the first home-based referral. Fidelity in implementing the planned intervention was described using Kaplan-Meier estimation to compute conditional probabilities of being tracked and of being re-referred by the linkage-to-care team. Effect of the intervention on time to linkage-to-care was analysed using a Cox regression model censored for death, migration, and end of data follow-up.

RESULTS

Among the 2,837 individuals (73.7% female) included in the analysis, 904 (32%) were tracked at least once, and 573 of them (63.4%) were re-referred. Probabilities of being re-referred was 17% within six months of first referral and 31% within twelve months. Compared to individuals not re-referred by the intervention, linkage-to-care was significantly higher among those with at least one re-referral through phone call (adjusted hazard ratio [aHR] = 1.82; 95% confidence interval [95% CI] = 1.47-2.25), and among those with re-referral through both phone call and home visit (aHR = 3.94; 95% CI = 2.07-7.48).

CONCLUSIONS

Phone calls and home visits following HIV testing were challenging to implement, but appeared effective in improving linkage-to-care amongst those receiving the intervention. Such patient-centred strategies should be part of UTT programs to achieve the UNAIDS 95-95-95 targets.

Achieving the UNAIDS 90-90-90 targets: a comparative analysis of four large community randomised trials delivering universal testing and treatment to reduce HIV transmission in sub-Saharan Africa

BACKGROUND

Four large community-randomized trials examining universal testing and treatment (UTT) to reduce HIV transmission were conducted between 2012-2018 in Botswana, Kenya, Uganda, Zambia and South Africa. In 2014, the UNAIDS 90-90-90 targets were adopted as a useful metric to monitor coverage. We systematically review the approaches used by the trials to measure intervention delivery, and estimate coverage against the 90-90-90 targets. We aim to provide in-depth understanding of the background contexts and complexities that affect estimation of population-level coverage related to the 90-90-90 targets.

METHODS

Estimates were based predominantly on "process" data obtained during delivery of the interventions which included a combination of home-based and community-based services. Cascade coverage data included routine electronic health records, self-reported data, survey data, and active ascertainment of HIV viral load measurements in the field.

RESULTS

The estimated total adult populations of trial intervention communities included in this study ranged from 4,290 (TasP) to 142,250 (Zambian PopART Arm-B). The estimated total numbers of PLHIV ranged from 1,283 (TasP) to 20,541 (Zambian PopART Arm-B). By the end of intervention delivery, the first-90 target (knowledge of HIV status among all PLHIV) was met by all the trials (89.2%-94.0%). Three of the four trials also achieved the second- and third-90 targets, and viral suppression in BCPP and SEARCH exceeded the UNAIDS target of 73%, while viral suppression in the Zambian PopART Arm-A and B communities was within a small margin (~ 3%) of the target.

CONCLUSIONS

All four UTT trials aimed to implement wide-scale testing and treatment for HIV prevention at population level and showed substantial increases in testing and treatment for HIV in the intervention communities. This study has not uncovered any one estimation approach which is superior, rather that several approaches are available and researchers or policy makers seeking to measure coverage should reflect on background contexts and complexities that affect estimation of population-level coverage in their specific settings. All four trials surpassed UNAIDS targets for universal testing in their intervention communities ahead of the 2020 milestone. All but one of the trials also achieved the 90-90 targets for treatment and viral suppression. UTT is a realistic option to achieve 95-95-95 by 2030 and fast-track the end of the HIV epidemic.

"Some believe those who say they can cure it" perceived barriers to antiretroviral therapy for children living with HIV/AIDS: Qualitative exploration of caregivers experiences in tamale metropolis

BACKGROUND

HIV/AIDS is now a chronic disease, as adherence to anti-retrovirals impacts positively on the quality as well as expectancy of life. However, there exist multifaceted barriers to treatments for which children are most disadvantaged. Since Ghana subscribed to the "treat all" policy less percentage (25.5%) of children (2-14 years) living with HIV/AIDS have been enrolled on the antiretroviral program compared to other categories of the population by 2019. At present no study has explored these barriers to children living with HIV/AIDS enrollment and adherence. This study aims to explore the perceived barriers of caregivers of children living with HIV/AIDS in the Tamale Metropolis.

METHODS

We used descriptive phenomenology to explore the phenomena. Caregivers were purposively selected and interviewed till information became repetitive at the ninth (9th) caregiver. A semi-structured interview guide was used to collect data through face-to-face in-depth interviews which were audio recorded. The interviews lasted an average of 47 minutes. Audio interviews were transcribed verbatim (English) and translated back-to-back (Daghani) before analysis was done manually according to Collaizi's seven-step approach. We used the Guba and Lincoln guidelines to ensure the rigour of the study and its findings. Results are presented in themes and supported with quotes.

RESULTS

Six themes emerged from the analysis of the caregivers' transcripts; (1) denial of HIV/AID diagnosis, (2) stock-outs and privacy at the clinic, (3) busy schedule and poor support, (4) ignorance and alternative herbal cure, (5) stigma and discrimination, (6) transportation and distance.

CONCLUSION

Perceived barriers are multi-dimensional and encountered by all PLWHA, especially children. These barriers could derail the gains of HIV/AIDS interventions among children. Adherence counselling among caregivers alongside campaigns among faith and herbal healers are of grave concern to reduce myths of cure.

Exploring how outreach team leaders perceive community health workers' experiences of providing HIV services in KwaZulu-Natal, South Africa

Objectives: In 2018, the KwaZulu-Natal Department of Health launched the ward-based primary health care outreach teams policy framework which sought to expand the community health worker (CHW) programme's provision of longitudinal patient support, including human immunodeficiency virus (HIV) services in communities. This study sought to explore the perceptions of outreach team leaders who supervise CHWs on their experiences of providing HIV services in the province.Study design: This was a qualitative, phenomenology study.Methods: Convenience sampling was done to select one outreach team leader from each of the 11 KwaZulu-Natal health districts to be interviewed using an interview guide. Thematic analysis, guided by the Ritchie and Spencer framework analysis, was used to analyse the data.Results: The challenges faced by CHWs in delivering HIV services were: the absence of individuals when CHWs visited their homes, self-HIV stigma, rejection of CHWs' HIV services due to traditional beliefs, CHW shortages, lack of other resources, low levels of CWH education and a lack of training. On the other hand, the provision of HIV services was fascilitated by: supportive supervision, training, having cell phones and having a positive attitude towards providing HIV services by CHWs that were HIV-positive.Conclusion: The CHWs in KwaZulu-Natal face more challenges than enablers in the provision of HIV services. The delegation of HIV services to CHWs should be aligned with their holistic empowerment by eliminating barriers to the provision of HIV services.

A qualitative investigation of facilitators and barriers to DREAMS uptake among adolescents with grandparent caregivers in rural KwaZulu-Natal, South Africa

Adolescents with grandparent caregivers have experienced challenges including the death of one or both parents due to HIV in sub-Saharan Africa. They may be left out of existing HIV prevention interventions targeting parents and children. We investigated the facilitators and barriers to DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored and Safe) programme uptake among adolescents with grandparent caregivers across different levels of the socio-ecological model in rural South Africa. Data were collected in three phases (October 2017 to September 2018). Adolescents (13-19 years old) and their grandparent caregivers (≥50 years old) (n = 12) contributed to repeat in-depth interviews to share their perceptions and experiences regarding adolescents' participation in DREAMS. Data were triangulated using key informant interviews with DREAMS intervention facilitators (n = 2) to give insights into their experiences of delivering DREAMS interventions. Written informed consent or child assent was obtained from all individuals before participation. All data were collected in isiZulu and audio-recorded, transcribed verbatim and translated into English. Thematic and dyadic analysis approaches were conducted guided by the socio-ecological model. Participation in DREAMS was most effective when DREAMS messaging reinforced existing norms around sex and sexuality and when the interventions improved care relationships between the adolescents and their older caregivers. DREAMS was less acceptable when it deviated from the norms, raised SRH information that conflicts with abstinence and virginity, and when youth empowerment was perceived as a potential threat to intergenerational power dynamics. While DREAMS was able to engage these complex families, there were failures, about factors uniquely critical to these families, such as in engaging children and carers with disabilities and failure to include adolescent boys in some interventions. There is a need to adapt HIV prevention interventions to tackle care relationships specific to adolescent-grandparent caregiver communication.

Changing Knowledge and Attitudes Towards HIV Treatment-as-Prevention and "Undetectable = Untransmittable": A Systematic Review

People on HIV treatment with undetectable virus cannot transmit HIV sexually (Undetectable = Untransmittable, U = U). However, the science of treatment-as-prevention (TasP) may not be widely understood by people with and without HIV who could benefit from this information. We systematically reviewed the global literature on knowledge and attitudes related to TasP and interventions providing TasP or U = U information. We included studies of providers, patients, and communities from all regions of the world, published 2008–2020. We screened 885 papers and abstracts and identified 72 for inclusion. Studies in high-income settings reported high awareness of TasP but gaps in knowledge about the likelihood of transmission with undetectable HIV. Greater knowledge was associated with more positive attitudes towards TasP. Extant literature shows low awareness of TasP in Africa where 2 in 3 people with HIV live. The emerging evidence on interventions delivering information on TasP suggests beneficial impacts on knowledge, stigma, HIV testing, and viral suppression.

Thetha Nami: participatory development of a peer-navigator intervention to deliver biosocial HIV prevention for adolescents and youth in rural South Africa

BACKGROUND

Despite effective biomedical tools, HIV remains the largest cause of morbidity/mortality in South Africa - especially among adolescents and young people. We used community-based participatory research (CBPR), informed by principles of social justice, to develop a peer-led biosocial intervention for HIV prevention in KwaZulu-Natal (KZN).

METHODS

Between March 2018 and September 2019 we used CBPR to iteratively co-create and contextually adapt a biosocial peer-led intervention to support HIV prevention. Men and women aged 18-30 years were selected by community leaders of 21 intervention implementation areas (izigodi) and underwent 20 weeks of training as peer-navigators. We synthesised quantitative and qualitative data collected during a 2016-2018 study into 17 vignettes illustrating the local drivers of HIV. During three participatory intervention development workshops and community mapping sessions, the peer-navigators critically engaged with vignettes, brainstormed solutions and mapped the components to their own izigodi. The intervention components were plotted to a Theory of Change which, following a six-month pilot and process evaluation, the peer-navigators refined. The intervention will be evaluated in a randomised controlled trial ( NCT04532307 ).

RESULTS

Following written and oral assessments, 57 of the 108 initially selected participated in two workshops to discuss the vignettes and co-create the Thetha Nami (`talk to me'). The intervention included peer-led health promotion to improve self-efficacy and demand for HIV prevention, referrals to social and educational resources, and aaccessible youth-friendly clinical services to improve uptake of HIV prevention. During the pilot the peer-navigators approached 6871 young people, of whom 6141 (89%) accepted health promotion and 438 were linked to care. During semi-structured interviews peer-navigators described the appeal of providing sexual health information to peers of a similar age and background but wanted to provide more than just "onward referral". In the third participatory workshop 54 peer-navigators refined the Thetha Nami intervention to add three components: structured assessment tool to tailor health promotion and referrals, safe spaces and community advocacy to create an enabling environment, and peer-mentorship and navigation of resources to improve retention in HIV prevention.

CONCLUSION

Local youth were able to use evidence to develop a contextually adapted peer-led intervention to deliver biosocial HIV prevention.
