The power of peers and community in the continuum of HIV 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.

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.

Experiences of adolescents and youth with HIV testing and linkage to care through the Red Carpet Program (RCP) in Kenya

Adolescents and youth living with HIV (AYLHIV) experience worse health outcomes compared to adults. We aimed to understand the experiences of AYLHIV in care in the youth-focused Red-Carpet program in Kenya to assess the quality of service provision and identify programmatic areas for optimization. We conducted focus group discussions among 39 AYLHIV (15-24 years) and structured analysis into four thematic areas. Within the HIV testing theme, participants cited fear of positive results, confidentiality and stigma concerns, and suggested engaging the community and youth in HIV testing opportunities. Within the HIV treatment adherence theme, participants cited forgetfulness, stigma, adverse side effects, lack of family support, and treatment illiteracy as barriers to adherence. Most participants reported positive experiences with healthcare providers and peer support. In terms of the HIV status disclosure theme, AYLHIV cited concerns about their future capacity to conceive children and start families and discussed challenges with understanding HIV health implications and sharing their status with friends and partners. Youth voices informing service implementation are essential in strengthening our capacity to optimize the support for AYLHIV within the community, at schools and healthcare facilities.

A Systematic Review of Peer Support Interventions for Adolescents Living with HIV in Sub-Saharan Africa

Despite widespread availability of life-saving antiretroviral therapy (ART) in sub-Saharan Africa, AIDS remains one of the leading causes of death among adolescents living with HIV (ALHIV) in sub-Saharan Africa. The purpose of this article was to review the state of the science regarding interventions to improve ART adherence and/or HIV care retention among ALHIV throughout sub-Saharan Africa. The primary aim of this review was to describe the impact of peer support interventions in improving treatment outcomes (i.e., ART adherence and retention in HIV care) among ALHIV in sub-Saharan Africa. The secondary aim of this review was to determine whether these interventions may be efficacious at improving mental health outcomes. We identified 27 articles that met the eligibility criteria for our review, and categorized each article based on the type of peer support provided to ALHIV-individualized peer support, group-based support, and individualized plus group-based support. Results regarding the efficacy of these interventions are mixed and most of the studies included were deemed moderate in methodological quality. Although studies evaluating group-based peer support interventions were the most common, most of these studies were not associated with retention, adherence, or mental health outcomes. More robust, fully powered studies are needed to strengthen our knowledge base regarding peer support for ALHIV.

The association between HIV diagnosis disclosure and adherence to anti-retroviral therapy among adolescents living with HIV in Sub-Saharan Africa: A systematic review and meta-analysis

INTRODUCTION

Nine in ten of the world's 1.74 million adolescents living with human immunodeficiency virus (ALHIV) live in Sub-Saharan Africa. Suboptimal adherence to antiretroviral therapy (ART) and poor viral suppression are important problems among adolescents. To guide intervention efforts in this regard, this review presented pooled estimates on the prevalence of adherence and how it is affected by disclosure of HIV status among ALHIV in Sub-Saharan Africa.

METHODS

A comprehensive search in major databases (Excerpta Medica database (EMBASE), PubMed, Ovid/MEDLINE, HINARI, and Google Scholar) with additional hand searches for grey literature was conducted to locate observational epidemiologic studies published in English up to November 12, 2022 with the following inclusion criteria: primary studies that reported disclosure of HIV status as an exposure variable, had positive adherence to ART as an outcome, and conducted among adolescents and children. The COVIDENCE software was used for a title/abstract screening, full-text screening, the JBI quality assessment checklist, and data extraction. Random effects model was used to pool estimates. Furthermore, sensitivity analysis and subgroup analysis were also conducted by age groups and type of adherence measures used.

RESULTS

This meta-analysis combines the effect estimates from 12 primary studies with 4422 participants. The prevalence of good adherence to ART was 73% (95% CI (confidence interval): 56 to 87; I2 = 98.63%, P = <0.001), and it was higher among adolescents who were aware of their HIV status, 77% (95% CI: 56 to 92; I2 = 98.34%, P = <0.001). Overall, knowledge of HIV status was associated with increased odds of adherence (odds ratio (OR) = 1.88, 95% CI: 1.21 to 2.94; I2 = 79.8%, P = <0.001). This was further supported in a subgroup analysis by age (seven studies, pooled OR = 1.89, 95% CI: 1.06 to 3.37; I2 = 81.3%, P = <0.0001) and whether primary studies controlled for confounding factors (six studies provided adjusted estimates, pooled OR = 2.61, 95% CI: 1.22 to 5.57; I2 = 88.1%, P = <0.001) confirmed this further.

CONCLUSIONS

Our meta-analysis and systematic review revealed that knowledge of one's HIV status was associated with adherence to ART, particularly among adolescents. The findings underscored the importance of encouraging disclosure in order to enhance adherence among adolescents.

Exploring the beliefs, experiences and impacts of HIV-related self-stigma amongst adolescents and young adults living with HIV in Harare, Zimbabwe: A qualitative study

Background

HIV-related self-stigma is a significant barrier to HIV management. However, very little research has explored this phenomenon, particularly in sub-Saharan Africa. This study explored the beliefs, experiences, and impacts of HIV self-stigma amongst adolescents and young adults (AYALHIV) in Harare, Zimbabwe to inform future interventions. It aimed to capture the lived experience of self-stigmatization among AYALHIV and its impact on their social context using Corrigan et al (2009) self-stigma framework of ‘awareness’, ‘agreement’, and ‘application’.

Methods

Virtual semi-structured key informant interviews were conducted between June and July 2020 with adolescents and young adults (Female = 8; Male = 8) living with HIV (18–24 years) in Harare, Zimbabwe. We conducted the interviews with a purposive sample of AYALHIV enrolled in Africaid’s ‘Zvandiri’ program which provides HIV support services. Interviews were mainly conducted in English and with three in Shona, the main indigenous language. Audio-recorded qualitative data were transcribed, translated into English (where necessary) and deductively coded using Corrigan et al.’s self-stigma framework. The outbreak of SARS-CoV-2 coincided with the commencement of data collection activities, which impacted on both the sample size and a shift from in-person to virtual interviewing methods.

Results

Sixteen respondents (50% male) took part in the interviews. The mean age of respondents was 22 years. All respondents reported HIV-related self-stigma either occasionally or frequently. Three main themes of self-stigmatizing experiences emerged: disclosure, relationships, and isolation. These themes were then analyzed within the self-stigma development framework by Corrigan et al. (2009) known as ‘the three As’: awareness, agreement, and application of self-stigmatizing thoughts. Respondents’ experiences of self-stigma reportedly led to poor well-being and decreased mental and physical health. Gendered experiences and coping mechanisms of self-stigma were reported. Data suggested that context is key in the way that HIV is understood and how it then impacts the way people living with HIV (PLHIV) live with, and experience, HIV.

Conclusions

HIV-related negative self-perceptions were described by all respondents in this study, associated with self-stigmatizing beliefs that adversely affected respondents’ quality of life. Study findings supported Corrigan et al.’s framework on how to identify self-stigma and was a useful lens through which to understand HIV-related self-stigma among young people in Harare. Study findings highlight the need for interventions targeting PLHIV and AYALHIV to be context relevant if they are to build individual resilience, while working concurrently with socio-political and systemic approaches that challenge attitudes to HIV at the wider societal levels. Finally, the gendered experiences of self-stigma point to the intersecting layers of self-stigma that are likely to be felt by particularly marginalized populations living with HIV and should be further explored.

HIV and Intersectional Stigma Reduction Among Organizations Providing HIV Services in New York City: A Mixed-Methods Implementation Science Project

Stigma remains a pervasive barrier to Ending the HIV Epidemic (EHE) in New York City (NYC). As part of an EHE implementation science planning process, we mapped multi-level HIV-related stigma-reduction activities, assessed their evidence base, and characterized barriers and facilitators. We interviewed and surveyed a convenience sample of 27 HIV prevention and/or treatment services organizations in NYC, March-August, 2020, using an embedded mixed-methods design. The greatest facilitators of stigma reduction included integration of health services, hiring staff who represent the community, and trainings. Intersecting stigmas were primarily addressed through the integration of HIV with mental health and substance use services. Barriers were multilevel, with organizational structure and capacity most challenging. A strong base of stigma-reduction activities was utilized by organizations, but intersectional frameworks and formal evaluation of activities’ impact on stigma were lacking. Effectiveness-implementation hybrid research designs are needed to evaluate and increase the uptake of effective stigma-reduction approaches in NYC.

Interventions to Improve Treatment Outcomes among Adolescents on Antiretroviral Therapy with Unsuppressed Viral Loads: A Systematic Review

Adolescents living with HIV (ALHIV) face unique developmental challenges that increase the risk of unsuppressed viral loads. Current reviews present a need for proven interventions to improve viral suppression among ALHIV on ART, who have a history of unsuppressed viral loads. This systematic review aims to synthesize and appraise evidence of the effectiveness of interventions to improve treatment outcomes among ALHIV with unsuppressed viral loads. Six bibliographic databases were searched for published studies and gray literature from 2010 to 2021. The risk of bias and certainty of evidence was assessed using the ROBINS-I tool, CASP checklists and GRADE. A total of 28 studies were eligible for full-text screening; and only three were included in the qualitative synthesis. In addition, two studies were included from website searches. Four types of interventions to improve viral suppression were identified, namely: intensive adherence counselling; community- and facility-based peer-led differentiated service delivery (DSD); family based economic empowerment; and conditional economic incentives and motivational interviewing. We strongly recommend peer-led community-based DSD interventions, intensive adherence counselling, and family-based economic empowerment as potential interventions to improve viral suppression among ALHIV.

Isisekelo Sempilo study protocol for the effectiveness of HIV prevention embedded in sexual health with or without peer navigator support (Thetha Nami) to reduce prevalence of transmissible HIV amongst adolescents and young adults in rural KwaZulu-Natal: a 2 × 2 factorial randomised controlled trial

Background

Antiretroviral therapy (ART) through universal test and treat (UTT) and HIV pre-exposure prophylaxis (PrEP) substantially reduces HIV-related mortality, morbidity and incidence. Effective individual-level prevention modalities have not translated into population-level impact in southern Africa due to sub-optimal coverage among adolescents and youth who are hard to engage. We aim to investigate the feasibility, acceptability, and preliminary population level effectiveness of HIV prevention services with or without peer support to reduce prevalence of transmissible HIV amongst adolescents and young adults in KwaZulu-Natal.

Methods

We are conducting a 2 × 2 factorial trial among young men and women aged 16–29 years, randomly selected from the Africa Health Research Institute demographic surveillance area. Participants are randomly allocated to one of four intervention combinations: 1) Standard of Care (SOC): nurse-led services for HIV testing plus ART if positive or PrEP for those eligible and negative; 2) Sexual and Reproductive Health (SRH): Baseline self-collected vaginal and urine samples with study-organized clinic appointments for results, treatment and delivery of HIV testing, ART and PrEP integrated with SRH services; 3) Peer-support: Study referral of participants to a peer navigator to assess their health, social and educational needs and provide risk-informed HIV prevention, including facilitating clinic attendance; or 4) SRH + peer-support.

The primary outcomes for effectiveness are: (1) the proportion of individuals with infectious HIV at 12 months and (2) uptake of risk-informed comprehensive HIV prevention services within 60 days of enrolment. At 12 months, all participants will be contacted at home and the study team will collect a dried blood spot for HIV ELISA and HIV viral load testing.

Discussion

This trial will enable us to understand the relative importance of SRH and peer support in creating demand for effective and risk informed biomedical HIV prevention and preliminary data on their effectiveness on reducing the prevalence of transmissible HIV amongst all adolescents and youth.

Acceptability of Community-Based Tuberculosis Preventive Treatment for People Living with HIV in Zimbabwe

As Zimbabwe expands tuberculosis preventive treatment (TPT) for people living with HIV (PLHIV), the Ministry of Health and Child Care is considering making TPT more accessible to PLHIV via less-intensive differentiated service delivery models such as Community ART Refill Groups (CARGs). We designed a study to assess the feasibility and acceptability of integrating TPT into CARGs among key stakeholders, including CARG members, in Zimbabwe. We conducted 45 key informant interviews (KII) with policy makers, implementers, and CARG leaders; 16 focus group discussions (FGD) with 136 PLHIV in CARGs; and structured observations of 8 CARG meetings. KII and FGD were conducted in English and Shona. CARG observations were conducted using a structured checklist and time-motion data capture. Ninety six percent of participants supported TPT integration into CARGs and preferred multi-month TPT dispensing aligned with ART dispensing schedules. Participants noted that the existing CARG support systems could be used for TB symptom screening and TPT adherence monitoring/support. Other perceived advantages included convenience for PLHIV and decreased health facility provider workloads. Participants expressed concerns about possible medication stockouts and limited knowledge about TPT among CARG leaders but were confident that CARGs could effectively provide community-based TPT education, adherence monitoring/support, and TB symptom screening provided that CARG leaders received appropriate training and supervision. These results are consistent with findings from pilot projects in other African countries that are scaling up both differentiated service delivery for HIV and TPT and suggest that designing contextually appropriate approaches to integrating TPT into less-intensive HIV treatment models is an effective way to reach people who are established on ART but who may have missed out on access to TPT.

Mapping HIV-related services for women in Eastern Canada: A qualitative study

Background:

Geographic health disparities have been well described in parts of Canada; however, little is known about the experiences of women living with HIV in the Maritime Provinces. This article focuses on the complex health system women living with HIV navigate geographically to access care in New Brunswick and Nova Scotia, Canada.

Method:

This study includes interviews with 10 women living with HIV and 39 community-based workers whose organizations provide services to this group of women in New Brunswick and Nova Scotia. Purposive sampling was used to recruit both women living with HIV and community workers. Interviews were recorded and transcribed into a Microsoft word document. Transcripts were imported into NVivo 11 for thematic analyses and used to map the services women with HIV were accessing in their communities in ArcGIS 10.2 for Windows.

Results:

The study found that there are a number of barriers women with HIV face in the Maritime Provinces, including the low number of specialist physicians, long travel distances to major urban centers for care, and the loss of HIV-specific supports and resources. In response to these difficulties, community-based organizations are leading efforts in their communities to increase outreach programs and the number of available peer workers to improve the health outcomes of women living with HIV. Furthermore, it showed that women living with HIV and community workers were interested in creating a women-centered HIV care system in the Maritime Provinces, but were uncertain how to move forward with this initiative.

Conclusion:

There is a need for women-centered HIV services. This study proposes streamlining the healthcare pathway and decreasing obstacles to increase women’s access to care in the Maritime Provinces.

Effect and implementation experience of intensive adherence counseling in a public HIV care center in Uganda: a mixed-methods study

Background

Intensive adherence counseling (IAC) is an intervention recommended by the World Health Organization to improve anti-retroviral therapy (ART) adherence among people living with HIV on ART with unsuppressed viral load; and in 2016, the intervention was implemented in Uganda. This study evaluated the effect and experiences of providing IAC in an urban HIV care center in Kampala, Uganda.

Methods

This was a sequential explanatory mixed-method study that compared viral load suppression during IAC implementation (intervention) to the period before IAC at Kisenyi Health centre IV. Data were abstracted from patient files and viral load register. The effect of IAC on viral load suppression and associated factors were analyzed using modified Poisson regression with robust standard errors. Using in-depth interviews and an inductive analysis approach in Atlas-ti 8. We also explored experiences of providing IAC among healthcare workers.

Results

A total of 500 records were sampled: 249 (49.8%) in the intervention period and 251 (51.2%) in the pre-intervention period. The mean age was lower during the intervention period 33.1 (± 12.0) than 36.5 (± 13.4) in the pre- intervention period, p = 0.002. More clients were currently on Protease-based regimen in the pre-intervention period 179 (71.3%) than 135 (54.2%) in the intervention period, p ≤ 0.001. In the intervention period, all eligible clients received IAC [249/249 (100.0%)]. Overall, 325 (65.0%) received IAC and of these, 143 (44.1%) achieved viral load suppression compared to 46 (26.3%) who received regular counseling. Receiving IAC significantly increased viral load suppression by 22% (aPR 1.22, 95% CI 1.01–1.47). Clients on Protease-based regimen were less likely to suppress than those on Efavirenz or Nevirapine-based regimens (aPR 0.11, 95% CI 0.08–0.15). All the interviewed healthcare workers lauded IAC for improving ART adherence. However, patient and health care system related factors hindered adherence during IAC.

Conclusions

The full potential of IAC in achieving viral load suppression in this setting has not been reached due to a combination of the patient and health care system related factors. Provision of adequate IAC necessities and use of patient centered approach should be emphasized to obtain the maximum benefit of the intervention.

The Role of Community Health Workers in HIV Care Engagement: A Qualitative Study of Stakeholder Perspectives in Tanzania

ABSTRACT

Suboptimal retention in HIV care is a major driver of the global epidemic, including in sub-Saharan Africa. In Tanzania, the national Community-Based HIV Services program integrates volunteer community health workers (CHWs) to support patient care engagement and reduce the burden placed on HIV clinic nurses; however, few studies have assessed the value of CHWs supporting HIV care. Qualitative interviews were conducted with 48 administrators, nurses, CHWs, and patients to explore strengths and limitations of the Community-Based HIV Services program. Stakeholders believed CHWs are uniquely positioned to establish trust and provide patient support. Patients who had frequent contact with CHWs described them as valued sources of education and encouragement, but fewer than half of the patients interviewed had ever met with a CHW. Clinic nurses described feeling disconnected from CHWs, and stakeholders highlighted the need for financial, logistical, and educational support to rejuvenate the program and effectively address care engagement challenges.

Integrating HIV services and other health services: A systematic review and meta-analysis

BACKGROUND

Integration of HIV services with other health services has been proposed as an important strategy to boost the sustainability of the global HIV response. We conducted a systematic and comprehensive synthesis of the existing scientific evidence on the impact of service integration on the HIV care cascade, health outcomes, and cost-effectiveness.

METHODS AND FINDINGS

We reviewed the global quantitative empirical evidence on integration published between 1 January 2010 and 10 September 2021. We included experimental and observational studies that featured both an integration intervention and a comparator in our review. Of the 7,118 unique peer-reviewed English-language studies that our search algorithm identified, 114 met all of our selection criteria for data extraction. Most of the studies (90) were conducted in sub-Saharan Africa, primarily in East Africa (55) and Southern Africa (24). The most common forms of integration were (i) HIV testing and counselling added to non-HIV services and (ii) non-HIV services added to antiretroviral therapy (ART). The most commonly integrated non-HIV services were maternal and child healthcare, tuberculosis testing and treatment, primary healthcare, family planning, and sexual and reproductive health services. Values for HIV care cascade outcomes tended to be better in integrated services: uptake of HIV testing and counselling (pooled risk ratio [RR] across 37 studies: 1.67 [95% CI 1.41-1.99], p < 0.001), ART initiation coverage (pooled RR across 19 studies: 1.42 [95% CI 1.16-1.75], p = 0.002), time until ART initiation (pooled RR across 5 studies: 0.45 [95% CI 0.20-1.00], p = 0.050), retention in HIV care (pooled RR across 19 studies: 1.68 [95% CI 1.05-2.69], p = 0.031), and viral suppression (pooled RR across 9 studies: 1.19 [95% CI 1.03-1.37], p = 0.025). Also, treatment success for non-HIV-related diseases and conditions and the uptake of non-HIV services were commonly higher in integrated services. We did not find any significant differences for the following outcomes in our meta-analyses: HIV testing yield, ART adherence, HIV-free survival among infants, and HIV and non-HIV mortality. We could not conduct meta-analyses for several outcomes (HIV infections averted, costs, and cost-effectiveness), because our systematic review did not identify sufficient poolable studies. Study limitations included possible publication bias of studies with significant or favourable findings and comparatively weak evidence from some world regions and on integration of services for key populations in the HIV response.

CONCLUSIONS

Integration of HIV services and other health services tends to improve health and health systems outcomes. Despite some scientific limitations, the global evidence shows that service integration can be a valuable strategy to boost the sustainability of the HIV response and contribute to the goal of 'ending AIDS by 2030', while simultaneously supporting progress towards universal health coverage.

Interventions for improving treatment outcomes in adolescents on antiretroviral therapy with unsuppressed viral loads: a systematic review protocol

INTRODUCTION

Adolescents represent one of the most underserved population groups among people living with HIV. With successes in the elimination of mother to child transmission initiatives and advances in paediatric HIV treatment programmes, a large population of HIV-infected children are surviving into adolescence. Adolescence presents unique challenges that increase the risk of non-suppressed viral loads in adolescents living with HIV (ALHIV). There is a need to develop, implement and test interventions to improve viral suppression among ALHIV. Systematic reviews of recent studies present scarce and inconclusive evidence of effectiveness of current interventions, especially for adolescents. This protocol provides a description of a planned review of interventions to improve treatment outcomes among unsuppressed ALHIV.

METHODS AND ANALYSIS

A comprehensive search string will be used to search six bibliographic databases: PubMed/MEDLINE, Sabinet, EBSCOhost, CINAHL, Scopus and ScienceDirect, for relevant studies published between 2010 and 2020 globally, and grey literature. Identified articles will be exported into Mendeley Reference Management software and two independent reviewers will screen the titles, abstracts and full texts for eligibility. A third reviewer will resolve any discrepancies between the two initial reviewers. Studies reporting on interventions to improve viral suppression, retention and adherence for adolescents will be considered for inclusion. The systematic review will be performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Where feasible, a meta-analysis will be conducted using Stata Statistical Software: Release V.16. The quality of the studies and risk of bias will be assessed using the Critical Appraisal Skills Programme checklists and Risk of Bias in Non-randomised Studies of Interventions tool, respectively.

ETHICS AND DISSEMINATION

The systematic review entails abstracting and reviewing already publicly available data rather than any involvement of participants, therefore, no ethical clearance will be required. Results will be shared with relevant policy-makers, programme managers and service providers, and published and share through conferences and webinars.

"Those People Motivate and Inspire Me to Take My Treatment." Peer Support for Adolescents Living With HIV in Cape Town, South Africa

Adherence to antiretroviral therapy (ART) and psychosocial support to manage stigma and disclosure is essential for adolescents living with HIV (ALHIV). Peer support groups can help ALHIV and their families live successfully with HIV. This qualitative study aimed to examine adolescent and caregiver perspectives on peer support groups. Three themes emerged: (1) peer support encouraged adherence to ART, (2) serostatus disclosure outside the family was perceived as difficult, and (3) the peer support group fostered fundamental and meaningful peer relationships for ALHIV. Caregivers felt peer support groups increased self-acceptance and adherence for ALHIV across 3 domains: (1) as motivation for families and adolescents, (2) to increase adolescent independence and maturity, and (3) to help adolescents accept their HIV status and live successfully with HIV. These data highlight the importance of psychosocial support groups for ALHIV and caregivers, illustrating the benefits of a safe space with trusted relationships and open communication.

'This is what is going to help me': Developing a co-designed and theoretically informed harm reduction intervention for mobile youth in South Africa and Uganda

ABSTRACTYoung migrants in sub-Saharan Africa are particularly vulnerable to HIV-acquisition. Despite this, they are consistently under-served by services, with low uptake and engagement. We adopted a community-based participatory research approach to conduct longitudinal qualitative research among 78 young migrants in South Africa and Uganda. Using repeat in-depth interviews and participatory workshops we sought to identify their specific support needs, and to collaboratively design an intervention appropriate for delivery in their local contexts. Applying a protection-risk conceptual framework, we developed a harm reduction intervention which aims to foster protective factors, and thereby nurture resilience, for youth 'on the move' within high-risk settings. Specifically, by establishing peer supporter networks, offering a 'drop-in' resource centre, and by identifying local adult champions to enable a supportive local environment. Creating this supportive edifice, through an accessible and cohesive peer support network underpinned by effective training, supervision and remuneration, was considered pivotal to nurture solidarity and potentially resilience. This practical example offers insights into how researchers may facilitate the co-design of acceptable, sustainable interventions.

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.

Effect of peer-distributed HIV self-test kits on demand for biomedical HIV prevention in rural KwaZulu-Natal, South Africa: a three-armed cluster-randomised trial comparing social networks versus direct delivery

STUDY OBJECTIVE

We investigated two peer distribution models of HIV self-testing (HIVST) in HIV prevention demand creation compared with trained young community members (peer navigators).

METHODS

We used restricted randomisation to allocate 24 peer navigator pairs (clusters) in KwaZulu-Natal 1:1:1: (1) standard of care (SOC): peer navigators distributed clinic referrals, pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) information to 18-30 year olds. (2) peer navigator direct distribution (PND): Peer navigators distributed HIVST packs (SOC plus two OraQuick HIVST kits) (3) incentivised peer networks (IPN): peer navigators recruited young community members (seeds) to distribute up to five HIVST packs to 18-30 year olds within their social networks. Seeds received 20 Rand (US$1.5) for each recipient who distributed further packs. The primary outcome was PrEP/ART linkage, defined as screening for PrEP/ART eligibility within 90 days of pack distribution per peer navigator month (pnm) of outreach, in women aged 18-24 (a priority for HIV prevention). Investigators and statisticians were blinded to allocation. Analysis was intention to treat. Total and unit costs were collected prospectively.

RESULTS

Between March and December 2019, 4163 packs (1098 SOC, 1480 PND, 1585 IPN) were distributed across 24 clusters. During 144 pnm, 272 18-30 year olds linked to PrEP/ART (1.9/pnm). Linkage rates for 18-24-year-old women were lower for IPN (n=26, 0.54/pnm) than PND (n=45, 0.80/pnm; SOC n=49, 0.85/pnm). Rate ratios were 0.68 (95% CI 0.28 to 1.66) for IPN versus PND, 0.64 (95% CI 0.26 to 1.62) for IPN versus SOC and 0.95 (95% CI 0.38 to 2.36) for PND versus SOC. In 18-30 year olds, PND had significantly more linkages than IPN (2.11 vs 0.88/pnm, RR 0.42, 95% CI 0.18 to 0.98). Cost per pack distributed was cheapest for IPN (US$36) c.f. SOC (US$64). Cost per person linked to PrEP/ART was cheaper in both peer navigator arms compared with IPN.

DISCUSSION

HIVST did not increase demand for PrEP/ART. Incentivised social network distribution reached large numbers with HIVST but resulted in fewer linkages compared with PrEP/ART promotion by peer navigators.

"We need our own clinics": Adolescents' living with HIV recommendations for a responsive health system

Adolescents living with HIV comprise a significant patient population in sub Saharan Africa but are poorly retained in care with consequent increased mortality and morbidity. We conducted in-depth interviews with 25 adolescents living with HIV engaged in care from five clinics in Johannesburg regarding their recommendations for the healthcare system. Findings included advocating for adolescent clinics, recognizing the importance of clinic-based support groups, valuing the influence lay counselors have in providing healthcare to adolescents, improving widespread education of vertical HIV transmission and meaningfully linking clinics to the community. Our study offers guidance to the differentiated care model recommended for adolescent treatment highlighting that a positive youth development approach and use of lay and peer counselors may act as cornerstones of this model. Serving the mental health needs of adolescents living with HIV in a responsive manner may strengthen their use of the system and elevate it to a source of resilience.

It helps to talk: A guiding framework (TRUST) for peer support in delivering mental health care for adolescents living with HIV

INTRODUCTION

Adolescents living with HIV have poor treatment outcomes, including lower rates of viral suppression, than other age groups. Emerging evidence suggests a connection between improved mental health and increased adherence. Strengthening the focus on mental health could support increased rates of viral suppression. In sub-Saharan Africa clinical services for mental health care are extremely limited. Additional mechanisms are required to address the unmet mental health needs of this group. We consider the role that community-based peer supporters, a cadre operating at scale with adolescents, could play in the provision of lay-support for mental health.

METHODS

We conducted qualitative research to explore the experiences of peer supporters involved in delivering a peer-led mental health intervention in Zimbabwe as part of a randomized control trial (Zvandiri-Friendship Bench trial). We conducted 2 focus group discussions towards the end of the trial with 20 peer supporters (aged 18-24) from across 10 intervention districts and audio recorded 200 of the peer supporters' monthly case reviews. These data were thematically analysed to explore how peer supporters reflect on what was required of them given the problems that clients raised and what they themselves needed in delivering mental health support.

RESULTS

A primary strength of the peer support model, reflected across the datasets, is that it enables adolescents to openly discuss their problems with peer supporters, confident that there is reciprocal trust and understanding derived from the similarity in their lived experiences with HIV. There are potential risks for peer supporters, including being overwhelmed by engaging with and feeling responsible for resolving relationally and structurally complex problems, which warrant considerable supervision. To support this cadre critical elements are needed: a clearly defined scope for the manageable provision of mental health support; a strong triage and referral system for complex cases; mechanisms to support the inclusion of caregivers; and sustained investment in training and ongoing supervision.

CONCLUSION

Extending peer support to explicitly include a focus on mental health has enormous potential. From this empirical study we have developed a framework of core considerations and principles (the TRUST Framework) to guide the implementation of adequate supportive infrastructure in place to enhance the opportunities and mitigate risks.

Community-Led Monitoring: When Community Data Drives Implementation Strategies

PURPOSE OF REVIEW

Communities occupy a central position in effective health systems, notably through monitoring of health service quality and by giving recipients of care a voice. Our review identifies community-led monitoring mechanisms and best practices.

RECENT FINDINGS

Implementation of community-led monitoring mechanisms improved service delivery at facility-level, health system-wide infrastructure and health outcomes among recipients of care. Successful models were community-led, collaborative, continuous and systematic, and incorporated advocacy and community education. Identifying and replicating successful community-led monitoring practices is a key pathway to equitable access to HIV and health services overall.

Scaling up peer-led community-based differentiated support for adolescents living with HIV: keeping the needs of youth peer supporters in mind to sustain success

INTRODUCTION

Low rates of viral suppression among adolescents living with HIV (ALHIV) indicate that more effective support is urgently required at scale. The provision of peer support has generated considerable enthusiasm because it has the potential to ameliorate the complex social and relational challenges which underpin suboptimal adherence. Little is known about the impact on young peer supporters themselves, which is the focus of this paper.

METHODS

We present qualitative findings from the Zvandiri trial investigating the impact of a peer support intervention on the viral load for beneficiaries (ALHIV, aged 13 to 19 years) in Zimbabwe. The Zvandiri peer supporters aged 18 to 24 years, known as community adolescent treatment supporters (CATS), are themselves living with HIV. Individual in-depth interviews were conducted in late 2018 with 17 CATS exploring their experiences of delivering peer support and their own support needs. Interviews were analysed iteratively using thematic analysis.

RESULTS

The CATS reported that being peer supporters improved their own adherence behaviour and contributed to an improved sense of self-worth. The social connections between the CATS were a source of comfort and enabled them to develop skills to manage the challenging aspects of their work. Two substantial challenges were identified. First, their work may reveal their HIV status. Second, managing the emotional labour of this caring work; given how commonly the complexity of the beneficiaries' needs mirrored the circumstances of their own difficult lives. Both challenges were ameliorated by the support the CATS provided to each other and ongoing supervision from the adult mentor. There was variation in whether they felt their roles were appropriately valued through the remuneration they received and within the health system. There was a consensus that their experience meant that they would graduate from being a CATS with transferable skills that could enhance their employability.

CONCLUSIONS

Their experiences illustrate the advantages and opportunities of being a CATS. To minimize potential harms, it is vital to ensure that they feel valued in their role, which can be demonstrated by the provision of appropriate remuneration, recognition and respect, and that there is continued investment in ongoing support through ongoing training and mentoring.

The association between diagnosis disclosure and adherence to antiretroviral therapy among adolescents living with HIV in sub-Saharan Africa: a protocol for systematic review and meta-analysis

INTRODUCTION

More than eight in ten of the world's 1.65 million adolescents living with human immunodeficiency virus (ALHIV) live in sub-Saharan Africa (SSA). Suboptimal adherence to antiretroviral therapy (ART) and poor viral suppression are reported among ALHIV which may in turn compromise the gains achieved so far. The evidence on whether knowing one's own human immunodeficiency virus (HIV) status and self-disclosure to others benefit adherence to ART or not is inconclusive. This review aims to estimate the association between knowing one's HIV status and self-disclosure on adherence to ART among ALHIV in SSA.

METHODS

Comprehensive search strings will be used to identify relevant observational studies published in English up to May 2020 in major databases: Excerpta Medica database (EMBASE), PubMed, and Ovid/MEDLINE. To access African studies and also to freely access subscription-based articles, the African Index Medicus (AIM) and the WHO HINARI databases will be searched. The AfroLib database will be searched to access the gray literature of African studies. We will use the COVIDENCE software for title/abstract screening, full-text screening, quality assessment, and data extraction. Two authors will independently screen retrieved articles, and a third author authorized to resolve conflicts will handle disagreements. The Joanna Briggs Institute's (JBI) critical appraisal tools will be used to assess study quality. Appropriate statistical tests will be conducted to quantify the between studies heterogeneity and for the assessment of publication bias. We will check individual study influence analysis and also do subgroup analysis. The STATA version 14.2 will be used for statistical analysis.

DISCUSSION

A high-level adherence to ART is required to achieve adequate viral suppression and improve quality of life. Consequently, the evidence on how adherence to ART differs with knowledge of one's own HIV status and self-disclosure may help guide interventions aimed at improving adherence to ART.
