Service delivery models that promote linkages to PrEP for adolescent girls and young women and men in sub-Saharan Africa: a scoping review

Comparing youth-friendly clinics to the standard of care for adolescent girls and young women in Malawi: A qualitative analysis

Adolescent girls and young women (AGYW) in sub-Saharan Africa (SSA) face difficulties accessing sexual and reproductive health (SRH) services. Youth-friendly service delivery models may prove an alternative to increase SRH service uptake. This analysis utilises evidence from the Girl Power-Malawi study, a study designed to compare the impact of different models of service delivery on SRH service uptake for AGYW. Three intervention clinics trained providers in youth-friendly health services (YFHS), engaged young peer educators in patient outreach, expanded hours and integrated various services into youth-dedicated spaces. A standard of care (SOC) clinic was included as a comparator. This paper draws on qualitative data from in-depth interviews with 60 participants (15 per clinic) and 8 focus group discussions (2 per clinic). Thematic analysis identified three key themes regarding SRH service acceptability: having peer educators made AGYW feel more comfortable seeking services; AGYW perceived services at intervention clinics to be more private; and clinic modifications such as free services, longer operating hours and integration of different SRH services made services easier to access. Adolescents expressed that these factors contributed to higher service uptake in intervention clinics. Youth-friendly service provisions are needed to ensure AGYW find care-seeking acceptable.

Acceptability and Feasibility of Remote PrEP Visits for Adolescent Girls and Young Women in South Africa

The World Health Organization recommends differentiated service delivery (DSD) models for HIV prevention, including alternatives to clinic-based PrEP services. This study assessed the acceptability and feasibility of remote PrEP delivery-including HIV and pregnancy self-testing, and phone-based adherence counselling-among adolescent girls and young women (AGYW) in Johannesburg. The research was nested within the PrEP SMART trial (2019-2022), which evaluated scalable adherence support strategies for AGYW aged 18-25. During COVID-19 lockdowns, PrEP refills and testing kits were delivered to participants' homes, and counselling was provided by phone. Using a phenomenological qualitative method, we conducted in-depth interviews with AGYW (n = 14) who had the option to complete remote PrEP visits (accepting or declining), study staff (n = 12), and key informants (n = 10) involved in PrEP programming. Thematic analysis explored experiences of remote delivery, focusing on acceptability and feasibility. AGYW found remote PrEP visits convenient, empowering, and time-saving. Procedures such as self-testing and phone counselling were generally acceptable, though some expressed anxiety about performing tests incorrectly and concerns over privacy, stigma, and unintentional disclosure of PrEP use at home. About half still preferred clinic-based visits. Staff and key informants recognized benefits, but highlighted challenges related to cost, sustainability, and provider workload. Suggestions for improvement included integrating contraception and partnering with community organizations. In conclusion, remote PrEP delivery is acceptable and feasible for many AGYW but not universally suitable. These findings support the inclusion of remote PrEP options in DSD models, with attention to privacy concerns and support for self-testing in this age group.

Pre-exposure prophylaxis (PrEP) awareness, use, and discontinuation among Lake Victoria fisherfolk in Uganda: A cross-sectional population-based study

There is limited population-level data on the pre-exposure prophylaxis (PrEP) care continuum in eastern Africa. Here, we assessed the PrEP care continuum following PrEP rollout in a Ugandan community with ~40% HIV seroprevalence. We used cross-sectional population-based data collected between September 3 and December 19, 2018 from a Lake Victoria fishing community in southern Uganda to measure levels of self-reported PrEP awareness, ever-use, and discontinuation following 2017 PrEP rollout via a U.S. President's Emergency Plan for AIDS Relief (PEPFAR)-supported phased implementation program. Our analysis included HIV-seronegative persons reporting having ever received an HIV test result. We examined associations between demographic, behavioral, and health utilization factors with each outcome using age-adjusted modified Poisson regression. There were 1,401 HIV-seronegative participants, of whom 1,363 (97.3%) reported ever receiving an HIV test result. Median age was 29 years (IQR: 23-36), and 42.3% (n = 577) were women. Most (85.5%; n = 1,166/1363) participants reported PrEP awareness, but few (14.5%; n = 197/1363) reported ever using PrEP. Among 47.7% (375/786) of men and 29.3% (169/577) of women PrEP-eligible at time of survey, 18.9% (n = 71/375) and 27.8% (n = 47/169) reported ever using PrEP, respectively. Over half (52.3%, n = 103/197) of those who had ever used PrEP, self-reported current use. In this Lake Victoria fishing community, there were low levels of PrEP use despite high levels of PrEP awareness and eligibility, particularly among men. Efforts that enhance awareness of HIV risk and increase PrEP accessibility may help increase PrEP use among HIV-seronegative persons in African settings with high HIV burden.

Assessing PrEP Initiation and Adherence Among High-Risk, Sexually Active Adolescents and Young Adults: A Population-Based Prospective Study Across Diverse Service Delivery Models in a High HIV Prevalent District in South Africa

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy for high-risk populations, including adolescent girls and young women (AGYW) and adolescent boys and young men (ABYM). While various PrEP-delivery models exist in South Africa, little is known about optimizing PrEP-uptake and adherence for AGYW and ABYM. This study explored preferred and feasible PrEP care models to enhance initiation and adherence among at-risk adolescents and young adults (AYAs) in a high-HIV prevalent rural district in South Africa. We conducted a longitudinal, population-based cohort study from August 2021 to July 2022 across 22 service delivery points (SDPs) in KwaZulu-Natal. High-risk, sexually active HIV-negative AGYW (15-24 years) and ABYM (15-35 years) were recruited from clinics, schools, and community-based youth zones. PrEP-uptake and adherence, based on national guidelines, were assessed using Pearson's Chi square test and binomial regression. Of 2,772 HIV-negative AYA, 781 (28%) initiated PrEP. Despite 65% being classified as high risk for HIV (p < 0.001), only 22% initiated PrEP. Initiation was higher in female (82%, p < 0.001) and among the 15-19 years (51%, p = 0.11). PrEP uptake varied significantly by SDPs, lowest in clinics (9%, p < 0.001), higher in youth zones (58%, p < 0.001), and highest in schools (73%, p < 0.001). Adherence declined significantly over time, dropping from 12% at one month to 2% at six months (p < 0.001). These findings highlight the need for targeted interventions in schools and communities, addressing barriers such as awareness, side effects, and accessibility. Expanding PrEP services to non-traditional settings may enhance uptake and adherence, reducing HIV risk among young people.

Study-to-Clinic Transition and Daily Oral PrEP Access Experiences Among AGYW in Eastern Cape, South Africa: Insights from the Community PrEP Study

Adolescent girls and young women (AGYW) face a high HIV burden, while PrEP persistence often declines post-trial. Understanding access outside research settings is key to improving study-to-clinic transitions. This study explored AGYW's experiences accessing PrEP in public clinics after The Community PrEP Study (CPS) in Eastern Cape, South Africa, a 24-month behavioral intervention. AGYW referred to clinics post-study (June-November 2021) were interviewed on their transition experiences. Interviewers categorized participants as PrEP continuation, discontinuation, or non-presentation. The qualitative team iteratively coded transcripts, used matrix analysis and discussions to examine referral experiences, clinic access, and PrEP motivations. While most accepted the transition, many missed study support. Continuation was linked to clinic adaptation, while discontinuation stemmed from access barriers. Non-presentation resulted from logistical and privacy concerns. Recommendations included youth-friendly provider training, alternative PrEP pick-up options, and service integration. Provider engagement and training remain critical for optimizing PrEP access, even with long-acting modalities.Trial registration number NCT03977181.

Community PrEP delivery for adolescent girls and young women: insights from the DREAMS PrEP Choice Study in Johannesburg, South Africa

Introduction

Long-acting pre-exposure prophylaxis (PrEP) methods have the potential to significantly reduce HIV acquisition and increase the uptake and effective use of PrEP among adolescent girls and young women (AGYW). We describe the implementation approach for delivering the PrEP ring and outline provider perspectives related to community-based service delivery.

Methods

The DREAMS PrEP Choice Study, a mixed-methods implementation science study delivering PrEP choice to women 18 years and older, was conducted in Johannesburg, South Africa. We extracted quantitative enrollment data from the routine patient management system (REDCap) and collected qualitative data from four focus group discussions with providers. Quantitative data are presented descriptively whilst qualitative data were analyzed using content and thematic analyses.

Results

Between October 2023 and April 2024, 657 participants were enrolled and offered PrEP choice. Most (72.1%, n = 474) participants were between 18 and 24 years old and accessed services at education and training institutions (52.1%, n = 342). Furthermore, 68.8% (n = 451) chose oral PrEP at enrollment, 26.6% (n = 175) chose the PrEP ring, and 3.2% (n = 20) selected no method. Most participants accessed services through a mobile truck (n = 365, 55.6%). There was a strong preference for nurse insertion of the ring on site (n = 103, 58.9%). Site setup, privacy, and access to running water, in alignment with national PrEP ring guidelines, were reported as barriers to implementation.

Conclusion

As one of the first studies to implement community-based services for PrEP choice, the early results indicate the feasibility of delivering this service with moderate uptake of PrEP by AGYW. Understanding the service delivery conditions required to offer informed choice is important for supporting national scale-up.

Marriage and Steady Relationships with Women in Men Who Have Sex with Men in Sub-Saharan Africa: A Mixed-Method Systematic Review and Meta-analyses

High HIV prevalence in Sub-Saharan African (SSA) in men who have sex with men (MSM) leads to greater risk for their wives and other steady female partners because of prolonged exposure. To provide insights into the context possibly contributing to the risk of HIV transmission from MSM to women, our mixed-method synthesis about MSM' marriage and steady relationships with cisgender women aimed to: (i) assess the extent of engagement in steady relationships with women and in risky behaviors with these women across SSA's four regions; (ii) explore the underlying dynamics within these relationships by gathering qualitative information. We used quantitative and qualitative data specifically pertaining to related to marriage or other steady relationships with women from a systematic review on men who have sex with both men and women (MSMW) in SSA (PROSPERO-CRD42021237836). Meta-analyses were performed on quantitative data for each region. Pooled proportions were calculated using random-effects models. Qualitative data were analyzed using thematic synthesis. Data were selected from 125 studies. For Southern, East and West Africa, the estimated pooled proportions of married MSM were 4% (95% CI 2-8%; n = 10 studies; 4183 MSM), 8% (6-11%; 19; 7070), and 7% (6-9%; 13; 4705). In Southern Africa, 29% (11-56%; 5; 1667) of MSM had steady female partners. In East Africa, 34% (14-61%; 5; 2003) were currently or previously married to women. Motives to marry women included a desire to have children, and to conform to heteronormative social norms and family pressure. Marriage was seen as a means to discontinue homosexual behaviors or, conversely, a way to secretly continue same-sex behaviors more freely. Procreative intentions and a desire for secrecy often deterred MSM from using HIV prevention methods with their wives. For some MSM, steady relationships with women provided them with mutual support. However, these relationships could also lead to stressful and conflict-ridden situations, potentially resulting in psychosocial and HIV-related risks for the MSM as well as their male and steady female partners. Steady relationships with women are common in MSM in SSA. Sexuality concealment strategies with steady female partners depend on the circumstances that lead MSM to enter into these relationships, and have various implications on sexual behaviors with both male and female partners. Community-based support, HIV research, prevention, and care programs should be adapted to MSM's different life situations to reduce direct HIV transmission risk to steady female partners.

Recruitment of Adolescent Girls and Young Women into an Early Oral PrEP Open- Label Study in Southern Africa: Lessons Learned from HPTN 082

Background

Adolescent girls and young women (AGYW) in southern Africa who are at high risk for HIV acquisition can mitigate this risk by using daily oral pre-exposure prophylaxis (PrEP) consistently. Using reflections from the community engagement teams in an early oral PrEP trial, this paper presents lessons learned from recruiting AGYW into the trial. It highlights experiences and strategies employed during the planning, readiness, and implementation phases of the trial.

Methods

The HIV Prevention Trials Network (HPTN) 082 was an open-label study of PrEP uptake and adherence conducted between October 2016 and October 2018 among 16- to 25-year-old women without HIV in Cape Town and Johannesburg, South Africa, and Harare, Zimbabwe. A joint community team meeting with team members from all three HPTN 082 sites garnered and synthesized team experiences by analysing fieldwork reflections, HPTN 082 study-led workshop summaries, project records, and Community Advisory Board (CAB) meeting minutes about lessons for stakeholder engagement that are relevant for PrEP introduction and service delivery.

Results

Using the Good Participatory Practice (GPP) framework, thighlighted the value of PrEP education, engagement with stakeholders during the formative phase, and the importance of peers and family as sources of information, support, and referral for adolescent study participants. In the first year of recruitment for HPTN 082, study participants reported they needed support for consistent daily oral PrEP use from parents and other adults, and efforts were intensified to engage parents and community stakeholders.

Conclusions

The introduction of daily oral PrEP, a novel HIV prevention for young African AGYW, required multiple strategies that were culturally sensitive, age-appropriate, and included peers, partners, parents, and other adults who influence health behaviours in AGYW.

Setting up a pharmacy HIV pre-exposure prophylaxis delivery model: Lessons and recommendations for implementation

No abstract available.

Preventing HIV in women in Africa

HIV incidence is declining globally, but around half of all new infections are in sub-Saharan Africa-where adolescent girls and young women bear a disproportionate burden of new infections. Those who sell sex are at particularly high risk. Despite declining incidence rates and availability of effective biomedical prevention tools, we are not on track, globally or in Africa, to achieve UNAIDS 2025 prevention targets. For those at risk, interventions that strengthen their motivation, capabilities and access to all available HIV prevention technologies are critical-for adolescent girls and women in particular, but also for epidemic control more broadly. Exciting possibilities for scaling up new and highly effective prevention technologies are close, but delivery, implementation and financing models need to be developed and urgently evaluated, in partnership with communities, or these opportunities may be lost. Here, we discuss the evolving landscape of biomedical prevention technologies for women in Africa, their implementation and financing, as well as priorities for HIV prevention research in this setting.

A pilot cluster randomized controlled trial assessing uptake of PrEP and contraception in hair salons in South Africa

BACKGROUND

Women in South Africa have a high burden of HIV infections, STIs, and unintended pregnancies. Women congregate regularly in hair salons, which may be useful venues for HIV and sexual and reproductive health (SRH) services. Our objective was to assess the uptake of PrEP and contraception in hair salons in South Africa.

METHODS

We conducted a pilot cluster randomized controlled trial to evaluate uptake of a hair stylist-initiated, nurse-supported intervention offering a dynamic choice of contraception (oral or injectable), STI testing and treatment, and oral PrEP in 3 salons in urban KwaZulu-Natal. Rapid HIV testing was performed in a private area at enrollment and each PrEP dispensing. Women could receive contraception and/or oral PrEP at the initial visit or opt in at a later visit. We defined uptake as the proportion of eligible women who accepted salon-based PrEP and/or salon-based contraception at any visit. Control salon participants completed surveys and were referred to clinic. We assessed predictors of PrEP uptake among intervention participants using univariate logistic regression and multivariable logistic regression with age and potential predictors from the univariate analyses.

RESULTS

Among 134 participants in intervention salons, the median age was 26 years (IQR 22-29). 75% reported visiting the salon at least every 2 months. 27% were using hormonal contraception at enrollment, 31% reported a self-perceived moderate or great chance of getting HIV in the next year, 33% thought their primary sex partner had other partners, 65% did not use condoms in the past month, and 11% reported intimate partner violence (IPV). About half (49%) accepted salon-based PrEP, and 89% accepted salon-based contraception during the study. Adjusting for age, uptake of salon-based PrEP was associated with experiencing IPV (aOR 4.20, 95%CI: 1.02, 17.36).

CONCLUSIONS

When offering a dynamic choice of integrated SRH services in urban hair salons in South Africa, we reached young women with risk factors for HIV, STIs, and unintended pregnancies. Hair salons are a novel venue for reaching young women who may not perceive themselves at risk for HIV, STIs, and unintended pregnancies.

Systematic review of reviews on interventions to engage men and boys as clients, partners and agents of change for improved sexual and reproductive health and rights

OBJECTIVES

Evidence regarding interventions to engage men and boys to improve sexual and reproductive health and rights (SRHR) has grown rapidly across subtopics such as HIV, family planning and gender-based violence (GBV). We conducted a review of the effectiveness of interventions to engage men and boys across SRHR domains, lessons learnt about successful programming, and about harms/unintended consequences, in low- and middle-income countries (LMIC).

DESIGN

Systematic review of reviews following Cochrane guidelines.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Literature, Web of Science and Cochrane were searched (18 October-9 November 2022; 9 September 2024).

ELIGIBILITY CRITERIA

Eligible reviews were published since 2015, covered WHO-defined SRHR domain(s) and focused mostly on LMIC.

DATA EXTRACTION AND SYNTHESIS

Data extraction by multiple reviewers focused on intervention effectiveness, implementation best practices, unintended consequences, and quality/risk of bias.

RESULTS

Thirty-five systematic reviews were included, comprising ~960 primary studies. Reviews focused on HIV prevention/care, reproductive health, maternal and newborn health, and GBV. Reviews consistently concluded that men were successfully engaged, yielding benefits to both women and men's SRHR outcomes; no adverse intervention impacts on prevalence of SRHR outcomes were reported. We summarised the interventions most consistently found to be effective across reviews, in a programmer-friendly visual mapped onto a framework of men as clients, partners and agents of change. Person-centred, gender-transformative, multilevel approaches were most effective. Remaining evidence gaps include engaging men as contraceptive users, sexually transmitted infections other than HIV, preventing unsafe abortion and SGBV as experienced by men and boys.

CONCLUSIONS

There is substantial evidence supporting a range of successful interventions to engage men and boys to improve SRHR, with markedly similar principles and approaches emerging across SRHR domains. It is time to scale up and integrate these strategies, monitoring for any potential harms and tailoring as needed to socio-cultural contexts and for specific vulnerable subpopulations.

Community Perspectives on Optimizing Community Health Volunteer Roles for HIV Prevention Services in Kenya and Uganda

Community health workers (CHWs) play a significant role in supporting health services delivery in communities with few trained health care providers. There has been limited research on ways to optimize the role of CHWs in HIV prevention service delivery. This study explored CHWs' experiences with offering HIV prevention services [HIV testing and HIV pre- and post-exposure prophylaxis (PrEP and PEP)] during three pilot studies in rural communities in Kenya and Uganda, which aimed to increase biomedical HIV prevention coverage via a structured patient-centered HIV prevention delivery model. In-depth semi-structured interviews were conducted from November 2021 to March 2022 with CHWs (N = 8) and their clients (N = 18) in the Sustainable East Africa Research in Community Health (SEARCH) SAPPHIRE study. A seven-person multi-regional team coded and analyzed data using a thematic analysis approach. CHWs offered clients PrEP and PEP refills, adherence monitoring, counseling on medications, and phone consultations. Clients reported CHWs maintained close interpersonal relationships with clients, and demonstrated trustworthiness and professionalism. Some clients reported that community members trusted the authenticity of CHWs, while others expressed concerns about the CHWs' ability to maintain confidentiality, and felt that some community members would be uncomfortable receiving HIV services from them. CHWs valued the expansion of their role to include prevention services but expressed concerns about balancing competing demands of CHW responsibilities, income-generating activities, and family roles. CHWs were well accepted as HIV prevention service providers despite contextual challenges. CHWs need ongoing training support. Establishing structures for remunerating CHWs in health systems could improve their performance and retention.

Effective preexposure prophylaxis in young women and girls, a key population for HIV prevention

PURPOSE OF REVIEW

Although there is substantial momentum to scale up preexposure prophylaxis (PrEP) for HIV prevention in adolescent girls and young women (AGYW) at risk of HIV acquisition, this key population has demonstrated difficulty in sustained PrEP use. Despite being a user-controlled and discreet prevention option, effective oral PrEP use requires a series of complex daily decisions in the life of the PrEP user. In this review, we describe how the number of decisions AGYW have to execute for effective and continued PrEP use may potentially be reduced by providing simplified, integrated, differentiated sexual and reproductive health services that include PrEP, and introducing a choice of PrEP products, including less frequently dosed, longer acting and/or multipurpose prevention technology (MPT) products.

RECENT FINDINGS

PrEP uptake and effective use are enhanced when AGYW experience PrEP service delivery channels as convenient, integrated with their other sexual and reproductive health needs and matching their experiences (including limited autonomy) and lifestyle. Longer acting or less frequently dosed PrEP products or MPTs may reduce the cognitive burden associated with prevention decision-making and is, therefore, likely more suitable for the majority of AGYW who struggle with daily pill adherence.

SUMMARY

In the scaling up of HIV prevention for AGYW, implementers are encouraged to consider both PrEP products and PrEP delivery outlet preferences. Understanding and responding to AGYW's different needs will allow for preferred PrEP delivery outlets and choice in PrEP products, leading to a greater likelihood of effective PrEP use in this key population.

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.

HIV pre-exposure prophylaxis uptake, retention and adherence among female sex workers in sub-Saharan Africa: a systematic review

OBJECTIVE

To evaluate oral pre-exposure prophylaxis (PrEP) uptake, retention and adherence among female sex workers (FSWs) receiving care through community and facility delivery models in sub-Saharan Africa (SSA).

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

We searched online databases (PubMed, MEDLINE, SCOPUS, EMBASE, Google Scholar, Cochrane Database of Systematic Reviews and Web of Science) between January 2012 and 3 April 2022.

ELIGIBILITY CRITERIA FOR STUDIES

Randomised controlled trials, cohort studies, cross-sectional studies and quasi-experimental studies with PrEP uptake, adherence and retention outcomes among FSWs in SSA.

DATA EXTRACTION AND SYNTHESIS

Seven coders extracted data. The framework of the Cochrane Consumers and Communication Review Group guided data synthesis. The Risk of Bias In Non-Randomized Studies of Interventions tool was used to evaluate the risk of bias. Meta-analysis was conducted using a random-effects model. A narrative synthesis was performed to analyse the primary outcomes of PrEP uptake, adherence and retention.

RESULTS

Of 8538 records evaluated, 23 studies with 40 669 FSWs were included in this analysis. The pooled proportion of FSWs initiating PrEP was 70% (95% CI: 56% to 85%) in studies that reported on facility-based models and 49% (95% CI: 10% to 87%) in community-based models. At 6 months, the pooled proportion of FSWs retained was 66% (95% CI: 15% to 100%) for facility-based models and 83% (95% CI: 75% to 91%) for community-based models. Factors associated with increased PrEP uptake were visiting a sex worker programme (adjusted OR (aOR) 2.92; 95% CI: 1.91 to 4.46), having ≥10 clients per day (aOR 1.71; 95% CI: 1.06 to 2.76) and lack of access to free healthcare in government-run health clinics (relative risk: 1.16; 95% CI: 1.06 to 1.26).

CONCLUSIONS

A hybrid approach incorporating both facility-based strategies for increasing uptake and community-based strategies for improving retention and adherence may effectively improve PrEP coverage among FSWs.

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.

Barriers to the uptake of oral pre-exposure prophylaxis among young key populations in Nigeria

BACKGROUND

Young key populations (YKP) contribute to the burden of HIV in Nigeria and are a priority population for oral pre-exposure prophylaxis (PrEP). However, their uptake of PrEP remains low. We assessed the main barriers to PrEP uptake and the variation among YKP (15-24 years) in Nigeria.

METHODS

This study was a secondary data analysis of the 2020 Integrated Biological & Behavioural Surveillance Survey conducted among key populations (KP), including female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID), and transgender people (TG), in 12 states in Nigeria. A closed-ended question asking the main reason for not taking PrEP among KP who had never taken PrEP was included in the surveillance questionnaire. We collapsed the responses into six barrier themes. Using multinomial logistic regression analysis, we examined the association between the barriers (dependent variable) and KP group (independent variable), controlling for age, educational attainment, religion, marital status, employment status, and geopolitical zone.

RESULTS

A total of 1776 YKP were included in this study. The most cited barriers by KP group were: lack of access (28.3%) and fear of side effects (28.3%) by FSW; lack of interest (37.1%) by MSM; low risk perception (65.5%) by PWID; and lack of access (34.4%) by TG. The odds of reporting fear of side effects, lack of access, lack of interest, and nonspecific/others reasons were significantly different by KP group.

CONCLUSIONS

The barriers limiting the uptake of PrEP among YKP vary by KP group. Our results highlight the need for KP-specific interventions to improve the uptake of PrEP among YKP in Nigeria.

Pre-exposure prophylaxis (PrEP) knowledge, use, and discontinuation among Lake Victoria fisherfolk in Uganda: a cross-sectional population-based study

Background

There are limited population-level data on the pre-exposure prophylaxis (PrEP) care continuum in eastern Africa. Here, we assessed the PrEP care continuum following PrEP rollout in a Ugandan community with ~40% HIV seroprevalence.

Methods

We used cross-sectional population-based data collected between September 3 and December 19, 2018 from a Lake Victoria fishing community in southern Uganda to measure levels of self-reported PrEP knowledge, ever use, and discontinuation following 2017 PrEP rollout via a U.S. President's Emergency Plan for AIDS Relief (PEPFAR)-supported phased implementation program. Our analysis included HIV-seronegative persons reporting having ever received an HIV test result. We examined associations between demographic, behavioral, and health utilization factors with each outcome using age-adjusted modified Poisson regression.

Results

There were 1,401 HIV-seronegative participants, of whom 1,363 (97.3%) reported ever receiving an HIV test result. Median age was 29 years (IQR: 23-36), and 42.3% (n=577) were women. Most (85.5%; n=1,166) participants reported PrEP knowledge, but few (14.5%; n=197) reported ever using PrEP. Among 375 (47.7%) men and 169 (29.3%) women PrEP-eligible at time of survey, 18.9% (n=71) and 27.8% (n=47) reported ever using PrEP, respectively. Over half (52.3%, n=103) of those who had ever used PrEP, self-reported current use.

Conclusion

In this Lake Victoria fishing community, there were low levels of PrEP use despite high levels of PrEP awareness and eligibility, particularly among men. Efforts that enhance awareness of HIV risk and increase PrEP accessibility may help increase PrEP use among HIV-seronegative persons in African settings with high HIV burden.

Perspectives of female sex workers on HIV pre-exposure prophylaxis delivery in Uganda: A qualitative study

Background

HIV pre-exposure prophylaxis (PrEP) is underutilized by cisgender female sex workers (FSW) despite its proven effectiveness. This study aimed to understand the experiences of FSW with PrEP services in Uganda to inform HIV programming for this key population.

Methods

We conducted qualitative interviews with 19 FSW between June and July 2022 at the Most at Risk Populations Initiative clinic, Mulago Hospital, Kampala, to explore experiences with accessing PrEP Indepth interviews explored: (1) descriptions of where and how PrEP was obtained; (2) perspectives on current approaches for accessing PrEP; and (3) individual encounters with PrEP services. Data were analyzed through inductive thematic analysis.

Results

Three key themes emerged for FSW perspectives on PrEP service delivery. FSW highlighted the positive impact of a welcoming clinic environment, which motivated FSW to initiate PrEP and fostered a sense of connectedness within their community. They also reported feeling accepted, secure, and free from prejudice when accessing PrEP through facility-based services. The second explores the obstacles faced by FSW, such as lengthy wait times at clinics, inadequate provider support, and lack of sensitivity training which hindered their access to PrEP The third sheds light on how HIV-related stigma negatively impacted the delivery of community-based PrEP for FSW. While community-based distribution offered convenience and helped mitigate stigma, clinic-based care provided greater anonymity and was perceived as offering higher-quality care. Overall, FSWs emphasized the critical role of friendly healthcare providers, social support, and non-stigmatizing environments in promoting successful utilization of PrEP.

Conclusion

The study findings offer insights that can support HIV programs in optimizing PrEP delivery for FSW. Establishing easily accessible drug pick-up locations, prioritizing privacy, addressing and improving health workers' attitudes, and providing regular reminders could enhance PrEP access for FSW and decrease HIV acquisition.

My Way: development and preliminary evaluation of a novel delivery system for PrEP and other sexual health needs of young women in Western Kenya

INTRODUCTION

Young women in sub-Saharan Africa are a priority population for HIV prevention, yet challenges with adherence and persistence to HIV pre-exposure prophylaxis (PrEP) are common. This study involved the development and pilot testing of My Way-a novel delivery system for PrEP and co-packaged sexual health services.

METHODS

My Way was developed in Kisumu, Kenya through a user-centred design process (2020). The intervention involves peer-delivery and support for HIV testing and PrEP use, self-collected vaginal swabs for sexually transmitted infection (STI) testing, pregnancy testing, oral contraceptive pills, self-injectable medroxyprogesterone and/or condoms. My Way was assessed among 16- to 24-year-old sexually active women in a randomized controlled trial versus standard of care (SoC; 2021-2022). Use of PrEP and other sexual health services were tracked at 1, 3 and 6 months for feasibility. Acceptability was determined by questionnaire. The effect of the intervention on tenofovir diphosphate (TFV-DP) levels was assessed by chi-square test (primary outcome); other predictors were explored with regression analysis.

RESULTS

Among 150 women, the median age was 22 years and the median number of sexual partners was 2. Moderate/severe depression was common (60%). In the intervention arm, peers made 88% (198/225) of possible kit deliveries (177 with PrEP) and 49 STIs were diagnosed. In the SoC arm, 24% (55/225) of expected clinic visits occurred (53 with PrEP); no STI testing was performed. TVF-DP was detected in 16 participants at 6 months: 16% (12/75) in the intervention arm versus 5% (4/75) in the SoC arm (p = 0.03). Persistence among those with ongoing HIV prevention needs (i.e. prevention-effective persistence) was 18% (12/67) versus 7% (4/56; p = 0.08). No women acquired HIV. The intervention was significantly associated with detectable TFV-DP (OR 3.5, 1.1-11.4; p = 0.04); moderate/severe depression trended towards an association with TFV-DP (OR 0.2, 0.03-1.6; p = 0.13).

CONCLUSIONS

My Way is a promising delivery system for PrEP and other sexual health services among young women in Western Kenya. We found high feasibility and acceptability. PrEP use was modest, but higher with My Way compared to SoC. Long-acting PrEP formulations may overcome important barriers to PrEP use and should be explored in combination with the My Way delivery model.

Youth-friendly services was the magic: Experiences of adolescent girls and young women in the community PrEP study, South Africa

Adherence to daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been challenging for adolescent girls and young women (AGYW). As part of The Community PrEP Study (CPS), AGYW were randomised to HIV-prevention empowerment counselling (intervention) or basic medication pick-up (control). In this qualitative sub-study, we interviewed AGYW participants (n = 39) to explore PrEP use and study experiences by study arm, and study staff (n = 7) to explore study implementation, site environment, and participant engagement. Data were thematically analysed using a constant comparison approach. Comparative matrices assessed similarities and differences in study experiences and PrEP support preferences. Friendly, non-judgmental, non-stigmatizing study staff were described as central to participant's positive experiences. Participants highly valued CPS staff's holistic health support (e.g. physical and psycho-social). Intervention participants described empowerment counselling as helpful in supporting PrEP disclosure. However, control participants also described disclosing PrEP use to trusted individuals. Participants and staff recommended public-sector PrEP services provide holistic, confidential, and integrated sexual and reproductive health services, and community sensitisation. An adolescent and youth-friendly environment was the primary factor motivating AGYW's study engagement. While HIV-prevention empowerment counselling was well received, welcoming, respectful and non-judgmental staff may be the 'secret sauce' for implementing effective PrEP services to AGYW.

Pre-exposure prophylaxis access, uptake and usage by young people: a systematic review of barriers and facilitators

Background

Young people's sexual health decision-making, including decisions to access and adhere to HIV prevention strategies such as Pre-Exposure Prophylaxis (PrEP), are influenced by a range of internal and external factors. Synthesizing these factors is essential to guide the development of youth-focused PrEP health promotion strategies to contribute to international goals of ending HIV transmission.

Objective

To understand the individual, interpersonal, sociocultural and systemic barriers and facilitators to PrEP access, uptake and use experienced by young people 24 years and younger.

Design

A systematic review that adhered to the Preferred Reporting Items of Systematic Review and Meta-Analysis Protocols.

Data Sources and Methods

Eight databases (PubMed, Scopus, Cochrane, Medline, CINAHL, JBI, EMBASE, Web of Science) were systematically searched using terms related to young people, HIV and PrEP use. A narrative synthesis approach was used to delineate key barriers and facilitators to PrEP access, uptake and use.

Results

Of 11,273 returned articles, 32 met the eligibility criteria for inclusion: 18 from the United States, 10 from African nations and two from Brazil. Barriers and facilitators to PrEP access, uptake and use experienced by young people were identified across intrapersonal, interpersonal, community and systems levels. These factors are described under four overarching themes that relate to knowledge, side effects and perceptions of risk; attitudes and perceptions of family and partners; community attitudes and stigma; and negative healthcare provider experiences and difficulties navigating complex costly healthcare systems.

Conclusion

Findings suggest individual-level factors need consideration alongside the impacts of healthcare systems and broader systemic sociocultural structures within young people's relationships when developing PrEP health promotion strategies and services. Without considering these wider external implications to access, uptake and use of PrEP, global targets towards the elimination of HIV transmission will likely remain out of reach.

An implementation strategy package (video education, HIV self-testing, and co-location) improves PrEP implementation for pregnant women in antenatal care clinics in western Kenya

Background

Pre-exposure prophylaxis (PrEP) is recommended by the World Health Organization and the Kenyan Ministry of Health for HIV prevention in pregnancy and postpartum for women at risk for HIV. Integration of PrEP into antenatal care is promising, but delivery gaps exist in the face of healthcare provider shortages in resource-limited settings.

Methods

Between May and November 2021, we conducted a difference-in-differences study (3 months pre-intervention data collection and 3 months post-intervention data collection) analyzing four intervention facilities, where the strategies were implemented, and four comparison facilities, where no strategies were implemented. We tested a combination of three implementation strategies-video-based PrEP information in the waiting bay, HIV self-testing, and dispensing of PrEP in the antenatal care rooms-to improve PrEP delivery. We compared absolute changes in the proportion of antenatal attendees screened for PrEP (PrEP penetration), the proportion receiving all PrEP-specific steps in a visit (HIV testing, risk screening, and PrEP counseling) (PrEP fidelity), and client PrEP knowledge, client satisfaction, and waiting time and service time (a priori outcomes); post hoc, we compared the proportion offered PrEP (PrEP offer) and completing HIV testing. We measured provider perceptions of the acceptability and appropriateness of the implementation strategies.

Results

We observed significant improvements in PrEP penetration, PrEP offer, satisfaction, and knowledge (p < 0.05) and improvements in fidelity that trended towards significance (p = 0.057). PrEP penetration increased 5 percentage points (p = 0.008), PrEP fidelity increased 8 percentage points (p = 0.057), and PrEP offer increased 4 percentage points (p = 0.003) in intervention vs. comparison facilities. Client PrEP knowledge increased by 1.7 out of 6 total points (p < 0.001) and client satisfaction increased by 0.7 out of 24 total points (p = 0.003) in intervention vs. comparison facilities. We observed no changes in service time (0.09-min decrease; p = 0.435) and a small increase in waiting time (0.33-min increase; p = 0.005). HIV testing among those eligible did not change (1.5 percentage point decrease, p = 0.800). Providers felt the implementation strategies were acceptable and appropriate (median acceptability: 20/20; median appropriateness: 19.5/20). However, absolute levels of each step of the PrEP cascade remained suboptimal.

Conclusions

An implementation strategy package with video information, HIV self-testing, and co-location of medication dispensing enhanced PrEP delivery across several implementation outcomes and client satisfaction, while not substantially increasing wait time or decreasing provider-client contact time.

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.

Advancing the use of Long-Acting Extended Delivery formulations for HIV prevention in sub-Saharan Africa: challenges, opportunities, and recommendations

INTRODUCTION

The burden of HIV in sub-Saharan Africa (SSA) remains unacceptably high, and disproportionately affects girls and women. While the introduction of oral HIV pre-exposure prophylaxis (PrEP) in 2012 revolutionized HIV prevention, its effectiveness is dependent on user adherence and its implementation in SSA has faced numerous challenges. Patient-level, interpersonal and structural barriers, including, for example, daily pill burden, side effects, lack of partner support, testing and disclosure, and costs have been found to reduce adherence to oral PrEP.

DISCUSSION

Long-acting extended delivery (LAED) formulations for PrEP, such as injectable long-acting cabotegravir (CAB-LA) and dapivirine vaginal ring (DPV-VR) are critical additions to the HIV prevention toolkit and are especially important for populations such as adolescent girls and young women (AGYW) and other key populations who remain at significant risk of HIV acquisition while facing substantial barriers to preventive services. These LAED formulations have been shown to result in better adherence and fewer side effects, with CAB-LA being superior to oral PrEP in reducing the risk of HIV acquisition. They can be used to overcome user burden and adherence challenges. However, the successful rollout of the DPV-VR and CAB-LA may be hampered by issues such as a shortage of healthcare providers (HCPs), inadequate parenteral medication infrastructure, increased workload for HCPs, patient concerns, the price of the medications and the possibility of drug resistance.

CONCLUSIONS

SSA must develop laboratory capabilities for monitoring patients on LAED formulations and enhance research on developing more non-injectable LAED formulations. There is a need to train and retain more HCPs, implement task shifting, invest in healthcare infrastructure and integrate healthcare services. To reduce costs and improve availability, the region must advocate for patent license waivers for LAED formulations and procure drugs collectively as a region.
