Understanding Demand for PrEP and Early Experiences of PrEP Use Among Young Adults in Rural Kenya and Uganda: A Qualitative Study

Women's preferences for HIV prevention service delivery in pharmacies during pregnancy in Western Kenya: a discrete choice experiment

INTRODUCTION

Pharmacy-delivered HIV prevention services might create more options for pregnant women to use HIV prevention tools earlier and more consistently during pregnancy. We quantified preferences for attributes of potential HIV prevention services among women of childbearing age in Western Kenya.

METHODS

From June to November 2023, we administered a face-to-face discrete choice experiment survey to women aged 15-44 in Kenya's Homa Bay, Kisumu and Siaya counties. The survey evaluated preferences for HIV prevention services, described by seven attributes: service location, travel time, type of HIV test, sexually transmitted infection (STI) testing, partner HIV testing, pre-exposure prophylaxis (PrEP) and service fee. Participants answered a series of 12-choice questions. Each question asked them to select one of two service options or no services-an opt-out option. We used hierarchical Bayesian modelling levels to estimate each attribute level's coefficient and understand how attributes influenced service choice.

RESULTS

Overall, 599 participants completed the survey, among whom the median age was 23 years (IQR: 18-27); 33% were married, 20% had a job and worked regularly, and 52% had been pregnant before. Participants, on average, strongly preferred having any HIV prevention service option over none (opt-out preference weight: -5.84 [95% CI: -5.97, -5.72]). The most important attributes were the availability of PrEP (relative importance 27.04% [95% CI: 25.98%, 28.11%]), followed by STI testing (relative importance 20.26% [95% CI: 19.52%, 21.01%]) and partner HIV testing (relative importance: 16.35% [95% CI: 15.79%, 16.90%]). While, on average, participants preferred obtaining services at the clinic more than pharmacies, women prioritized the availability of PrEP, STI testing and partner HIV testing more than the location or cost.

CONCLUSIONS

These findings suggest the importance of providing comprehensive HIV prevention services and ensuring PrEP, STI testing and partner HIV testing are available. If pharmacies can offer these services, women are likely to access those services at pharmacies even if they prefer clinics.

"Something Like That": Awareness and Acceptability of HIV PrEP and PEP Among Kenyan Adolescents

BACKGROUND

Adolescents account for 15% of new HIV cases in Kenya. HIV pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are highly effective prevention tools, but uptake is low among adolescents, particularly in resource-limited settings. We assessed awareness and acceptability of PrEP and PEP among Kenyan adolescents.

METHOD

Focus group discussions were conducted with 120 adolescent boys and girls ages 15 to 19 in Kisumu. Data were analyzed using the Framework Approach.

RESULTS

Adolescent participants often had not heard of or could not differentiate between PrEP and PEP. They also confused these HIV prevention tools with emergency contraceptives. Taking a daily pill to prevent HIV was perceived as analogous to taking a pill to treat HIV. Boys were aware of and willing to consider using PrEP and PEP due to their dislike for using condoms. Adolescents identified insufficient information, cost, and uncomfortableness speaking with healthcare workers about their HIV prevention needs due to sexuality stigma as barriers to using PrEP and PEP.

CONCLUSION

Low awareness and poor understanding of PrEP and PEP among adolescents reveal the need for increased education and sensitization about these HIV prevention options. Expanding access to sexual and reproductive health services that are tailored to the needs of adolescents and staffed with non-judgmental providers could help reduce sexuality stigma as a barrier to accessing care. New HIV prevention approaches such as long-acting injectables or implants, on-demand regimens, and multipurpose prevention technologies may encourage increased uptake of PrEP and PEP by adolescents.

Exploring HIV risk perception mechanisms among youth in a test-and-treat trial in Kenya and Uganda

Understanding risk perception and risk-taking among youth can inform targeted prevention efforts. Using a health beliefs model-informed framework, we analysed 8 semi-structured, gender-specific focus group discussions with 93 youth 15-24 years old (48% male, 52% female), drawn from the SEARCH trial in rural Kenya and Uganda in 2017-2018, coinciding with the widespread introduction of PrEP. Highly connected social networks and widespread uptake of antiretrovirals shaped youth HIV risk perception. Amid conflicting information about HIV prevention methods, youth felt exposed to multiple HIV risk factors like the high prevalence of HIV, belief that people with HIV(PWH) purposefully infect others, dislike of condoms, and doubts about PrEP efficacy. Young women also reported minimal sexual autonomy in the context of economic disadvantages, the ubiquity of intergenerational and transactional sex, and peer pressure from other women to have many boyfriends. Young men likewise reported vulnerability to intergenerational sex, but also adopted a sexual conquest mentality. Comprehensive sexuality education and economic empowerment, through credible and trusted sources, may moderate risk-taking. Messaging should leverage youth's social networks to spread fact-based, gender- and age-appropriate information. PrEP should be offered alongside other reproductive health services to address both pregnancy concerns and reduce HIV risk.

The Effect of Disclosure of PrEP Use on Adherence Among African Young Women in an Open-Label PrEP Study: Findings from HPTN 082

To develop effective PrEP adherence interventions, it is important to understand the interplay between disclosure of pre-exposure prophalxis (PrEP) use, social support, and PrEP adherence. We leveraged the HPTN 082 study conducted among 451 adolescent girls and young women (AGYW) (ages 16 to 25 years, 2016 to 2019) in South Africa and Zimbabwe. Among the 349 who had month three disclosure and PrEP adherence data, 60% (n = 206) felt supported by adults, and 89% (n = 309) disclosed PrEP use to at least one person. PrEP disclosure was not associated with increased adherence, measured by intracellular tenofovir-diphosphate concentrations in dried blood spots. Women who reported having supportive adults, and disclosed to their parents, had higher adherence at 6 months with an increase of 177 fmol/punch (95% CI 12 to 343, t = 2.11, p = 0.04). PrEP interventions that help AGYW identify supportive relationships and effectively communicate the benefits of PrEP may improve PrEP adherence.Clinicaltrials.gov ID number: NCT02732730.

Experiences of oral pre-exposure prophylaxis use among heterosexual men accessing sexual and reproductive health services in South Africa: a qualitative study

INTRODUCTION

South African men face a substantial burden of HIV and are less likely to test for HIV and initiate antiretroviral therapy if tested positive and more likely to die from AIDS-related causes than women. In addition to condoms and circumcision, guidelines provide for the use of daily oral pre-exposure prophylaxis (PrEP) as an HIV prevention intervention for any men who recognize their need and request PrEP. However, heterosexual men have not been a focus of PrEP programmes, and since its introduction, there is limited literature on PrEP use among men in South Africa. This study explores the experiences, motivators and barriers to oral PrEP use among heterosexual men accessing primary healthcare services in South Africa.

METHODS

This study forms part of a mixed-methods implementation science study aimed at generating evidence for oral PrEP introduction and conducted in primary healthcare clinics in South Africa since 2018. Men aged ≥15 years who initiated oral PrEP and enrolled in a parent cohort study were purposefully invited to participate in an in-depth interview (IDI). Between March 2020 and May 2022, 30 men participated in IDIs exploring their motivators for PrEP use, and experiences with accessing health services. Interviews were audio recorded, transcribed and analysed thematically.

RESULTS

The final analysis included 28 heterosexual men (18-56 years old). Motivations to initiate PrEP included fear of acquiring HIV, self-perceived vulnerability to HIV and mistrust in relationships; health systems factors which motivated PrEP use included the influence of healthcare providers, educational materials and mobile services. Perceived reduction in HIV vulnerability and changing proximity to partners were reasons for PrEP discontinuation. Side effects, daily-pill burden and stigma were noted as challenges to PrEP use. Health system barriers to PrEP use included limited PrEP availability, school and work demands, and inconsistent mobile clinic schedules.

CONCLUSIONS

Our study reports on the experiences of heterosexual men accessing oral PrEP in real-world settings and contributes to the limited literature among this population. We highlight multiple levels which could be strengthened to improve men's PrEP use, including individual support, education among partners and communities, and addressing health system barriers to access.

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.

Dynamic choice HIV prevention intervention at outpatient departments in rural Kenya and Uganda

OBJECTIVE

HIV prevention service delivery models that offer product choices, and the option to change preferences over time, may increase prevention coverage. Outpatient departments in sub-Saharan Africa diagnose a high proportion of new HIV infections, but are an understudied entry point to biomedical prevention.

DESIGN

Individually randomized trial of dynamic choice HIV prevention (DCP) intervention vs. standard-of-care (SOC) among individuals with current/anticipated HIV exposure risk at outpatient departments in rural Kenya and Uganda (SEARCH; NCT04810650).

METHODS

Our DCP intervention included 1) product choice (oral preexposure prophylaxis [PrEP] or postexposure prophylaxis [PEP]) with an option to switch over time, 2) HIV provider- or self-testing, 3) service location choice (community vs. clinic-based), and 4) provider training on patient-centered care. Primary outcome was proportion of follow-up covered by PrEP/PEP over 48 weeks assessed via self-report.

RESULTS

We enrolled 403 participants (61% women; median 27 years, IQR 22-37). In the DCP arm, 86% ever chose PrEP, 15% ever chose PEP over 48 weeks; selection of HIV self-testing increased from 26 to 51% and of out-of-facility visits from 8 to 52%. Among 376 of 403 (93%) with outcomes ascertained, time covered by PrEP/PEP was higher in DCP (47.5%) vs. SOC (18.3%); difference = 29.2% (95% confidence interval: 22.7-35.7; P  < 0.001). Effects were similar among women and men (28.2 and 31.0% higher coverage in DCP, respectively) and larger during periods of self-reported HIV risk (DCP 64.9% vs. SOC 26.3%; difference = 38.6%; 95% confidence interval: 31.0-46.2; P  < 0.001).

CONCLUSION

A dynamic choice HIV prevention intervention resulted in two-fold greater time covered by biomedical prevention products compared to SOC in general outpatient departments in eastern Africa.

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

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

The development of a conceptual framework on PrEP stigma among adolescent girls and young women in sub-Saharan Africa

INTRODUCTION

Stigma is a well-known barrier to HIV testing and treatment and is an emerging barrier to pre-exposure prophylaxis (PrEP) use. To guide future research, measurement and interventions, we developed a conceptual framework for PrEP stigma among adolescent girls and young women (AGYW) in sub-Saharan Africa, a priority population for PrEP.

METHODS

A literature review, expert consultations and focus group discussions (FGDs) were conducted to adapt the Health Stigma and Discrimination Framework, describing the stigmatization process nested within the socio-ecological framework. We reviewed all articles on PrEP stigma and on HIV, contraceptive or sexuality stigma among AGYW from 2009 to 2019. Expert consultations were conducted with 10 stigma or PrEP researchers and two Kenyan youth advisory boards to revise the framework. Finally, FGDs were conducted with AGYW PrEP users (4 FGDs; n = 20) and key influencers (14 FGDs; n = 72) in Kenya with the help of a Youth Research Team who aided in FGD conduct and results interpretation. Results from each phase were reviewed and the framework was updated to incorporate new and divergent findings. This was validated against an updated literature search from 2020 to 2023.

RESULTS

The conceptual framework identifies potential drivers, facilitators and manifestations of PrEP stigma, its outcomes and health impacts, and relevant intersecting stigmas. The main findings include: (1) PrEP stigma is driven by HIV, gender and sexuality stigmas, and low PrEP community awareness. (2) Stigma is facilitated by factors at multiple levels: policy (e.g. targeting of PrEP to high-risk populations), health systems (e.g. youth-friendly service availability), community (e.g. social capital) and individual (e.g. empowerment). (3) Similar to other stigmas, manifestations include labelling, violence and shame. (4) PrEP stigma results in decreased access to and acceptability of PrEP, limited social support and community resistance, which can impact mental health and decrease PrEP uptake and adherence. (5) Stigma may engender resilience by motivating AGYW to think of PrEP as an exercise in personal agency.

CONCLUSIONS

Our PrEP stigma conceptual framework highlights potential intervention targets at multiple levels in the stigmatization process. Its adoption would enable researchers to develop standardized measures and compare stigma across timepoints and populations as well as design and evaluate interventions.

Methodological issues in qualitative research on HIV prevention: an integrative review

In view of the growing concern about the use of qualitative approach in health research, this article aims to analyze how the qualitative theoretical-methodological framework of HIV prevention is presented in empirical research. We conducted an integrative literature review with the following guiding questions: "How is the qualitative theoretical-methodological framework expressed in empirical research on HIV prevention?"; "What are the limits and potentials of the qualitative methodological designs employed?". In the qualitative methodological discussion, five dimensions guided the methodological course and the presentation of findings, from the analysis of the characterization of qualitative studies to the contextualization of the studies and the methodological approaches used, highlighting the use of semi-structured interviews with thematic content analysis. We also examined social categories and analytical references, drawing attention to the plurality of these theoretical-conceptual references and to the authors' polyphony, and identified the limits and potentials of qualitative research. This study focuses on a scientific topic that is related to a wide variety of social groups and analyzes how they are affected by it, examining issues related to social inequality and other analytical possibilities surrounding HIV prevention, and providing resources for a comprehensive methodological discussion. Hence, avoiding the risk of conducting qualitative research based on checklists that limit inventiveness and openness to different designs and forms of execution and analysis is as pivotal as ensuring that the research is consistent and detailed in publications.

A community-based dynamic choice model for HIV prevention improves PrEP and PEP coverage in rural Uganda and Kenya: a cluster randomized trial

INTRODUCTION

Optimizing HIV prevention may require structured approaches for providing client-centred choices as well as community-based entry points and delivery. We evaluated the effect of a dynamic choice model for HIV prevention, delivered by community health workers (CHWs) with clinician support, on the use of biomedical prevention among persons at risk of HIV in rural East Africa.

METHODS

We conducted a cluster randomized trial among persons (≥15 years) with current or anticipated HIV risk in 16 villages in Uganda and Kenya (SEARCH; NCT04810650). The intervention was a client-centred HIV prevention model, including (1) structured client choice of product (pre-exposure prophylaxis [PrEP] or post-exposure prophylaxis [PEP]), service location (clinic or out-of-clinic) and HIV testing modality (self-test or rapid test), with the ability to switch over time; (2) a structured assessment of patient barriers and development of a personalized support plan; and (3) phone access to a clinician 24/7. The intervention was delivered by CHWs and supported by clinicians who oversaw PrEP and PEP initiation and monitoring. Participants in control villages were referred to local health facilities for HIV prevention services, delivered by Ministry of Health staff. The primary outcome was biomedical prevention coverage: a proportion of 48-week follow-up with self-reported PrEP or PEP use.

RESULTS

From May to July 2021, we enrolled 429 people (212 intervention; 217 control): 57% women and 35% aged 15-24 years. Among intervention participants, 58% chose PrEP and 58% chose PEP at least once over follow-up; self-testing increased from 52% (baseline) to 71% (week 48); ≥98% chose out-of-facility service delivery. Among 413 (96%) participants with the primary outcome ascertained, average biomedical prevention coverage was 28.0% in the intervention versus 0.5% in the control: a difference of 27.5% (95% CI: 23.0-31.9%, p<0.001). Impact was larger during periods of self-reported HIV risk: 36.6% coverage in intervention versus 0.9% in control, a difference of 35.7% (95% CI: 27.5-43.9, p<0.001). Intervention effects were seen across subgroups defined by sex, age group and alcohol use.

CONCLUSIONS

A client-centred dynamic choice HIV prevention intervention, including the option to switch between products and CHW-based delivery in the community, increased biomedical prevention coverage by 27.5%. However, substantial person-time at risk of HIV remained uncovered.

Assessing the Preliminary Efficacy of a Nonrandomized, Clinic-Based HIV Risk Reduction Pilot Intervention for PrEP-Initiated, Alcohol- and Other Drug-Using Women of Color in Miami, FL

In this paper, we assessed the preliminary efficacy and acceptability of a quasi-experimental, clinic-based sexual risk reduction pilot intervention for pre-exposure prophylaxis (PrEP)-initiated, alcohol- and other drug-using women of color and explored their self-reported barriers to, and facilitators of, PrEP use. Using a mixed methods design, analyses incorporated pre- and post-intervention study assessment data from 38 women and semi-structured process evaluations using a subsample of 25. The intervention administered over an 8-week period consisted of 4 one-on-one in person educational sessions, a process evaluation, and study assessments conducted at baseline and 3 and 6 months. Post intervention, statistically significant changes in sexual risk scores were not observed; however, we found significant decreases in alcohol use (Z =  - 3.02, p = .003, η2 = .41). Process evaluation data revealed interpersonal relationships as a key motivator for PrEP initiation as well as a prominent barrier to PrEP use; these relationships rarely facilitated adherence. Overall, women found the intervention to be acceptable and reported a wide range of benefits of participation-most notably its therapeutic benefits. Findings from this study provide preliminary evidence of the potential for the Talking PrEP with Women of Color intervention to improve risky behaviors, knowledge, and attitudes related to sexual risk taking. Furthermore, findings suggest that interventions to increase PrEP uptake and adherence in at-risk women may benefit from supporting them in accurately estimating their risk for HIV and increasing their sense of social support.

Awareness of Heightened Sexual and Behavioral Vulnerability as a Trigger for PrEP Resumption Among Adolescent Girls and Young Women in East and Southern Africa

PURPOSE OF REVIEW

East and Southern Africa are the epicenter of the HIV epidemic. High HIV incidence rates among adolescent girls and young women (AGYW) remain stable over the last decade despite access to daily oral PrEP. Some settings have experienced high PrEP uptake among AGYW; however, discontinuation has been high. This review sought to understand drivers of PrEP discontinuation in this population in order to identify potential mechanisms to facilitate PrEP restart and optimize PrEP use.

RECENT FINDINGS

Drivers of PrEP discontinuation included low perceived HIV acquisition risk, PrEP-associated side effects, pill burden, family/sexual partner disapproval, lack of/intermittent sexual activity, PrEP use stigma, fear of intimate partner violence, misinformation about long-term PrEP use, and limited/inconsistent access to PrEP. The most frequently reported driver of PrEP discontinuation was low perceived HIV acquisition risk. This indicates that innovative interventions to help AGYW recognize their HIV risk and make informed decisions about PrEP use are urgently needed.

Preferences for oral PrEP dosing among adolescent boys and young men in three sub-Saharan African countries

BACKGROUND

HIV remains a leading contributor to the disease burden in sub-Saharan Africa, with adolescents and young people disproportionately affected. Optimising pre-exposure prophylaxis (PrEP) uptake has predominantly focused on women and adult men who have sex with men. We explore adolescent boys and young men's PrEP uptake preferences in South Africa, Uganda, and Zimbabwe.

METHODS

A cross-sectional sequential exploratory mixed-methods study amongst males aged 13-24 years was conducted between April and September 2019 as part of the CHAPS trial. Group discussions (GDs) and In-Depth Interviews (IDIs) focused on motivations and hindrances for HIV testing, PrEP preference, and reasons for the uptake of PrEP. A thematic approach was used to analyse the qualitative data. A quantitative survey following the qualitative work covered questions on demographics, HIV risk and PrEP preferences (on-demand vs. daily). For quantitative analysis, we fitted logistic regression models to determine factors associated with on-demand vs daily PrEP preference.

RESULTS

Overall, 647 adolescent boys and young men (median age 20, IQR: 17-22) were enrolled. Of these, 422 (65.22%) preferred on-demand PrEP (South Africa 45.45%, Uganda 76.80%, Zimbabwe 70.35%; p<0.001). Factors independently associated with on-demand PrEP included country (South Africa, adjusted odds ratio (aOR) = 0.19 [95%CI:0.1-0.3] compared to Uganda) and advanced planning of sex [>24 hours in advance aOR = 1.4 (0.9-2.3) compared to <2 hours]. Qualitatively, participants commonly believed they were not at risk of HIV acquisition most of the time and thought that on-demand PrEP would be suitable as they tend to plan sexual activity in advance.

CONCLUSION

Preference for on-demand PrEP is high in young males. The qualitative data support a preference for on-demand PrEP in those who plan sex in advance. HIV intervention programs should offer both on-demand and daily PrEP to engage more adolescent boys and young men in HIV prevention practices.

A Scoping Review of Oral Pre-exposure Prophylaxis for Cisgender and Transgender Adolescent Girls and Young Women: What Works and Where Do We Go from Here?

Adolescent girls and young women (AGYW) are disproportionately affected by HIV, and oral pre-exposure prophylaxis (PrEP) can reduce HIV acquisition. The purpose of this scoping review was to synthesize results from interventions along the PrEP continuum for AGYW to inform research and programs. We searched electronic databases for studies published between January 2012-July 2021 and conducted secondary reference searching. Studies were included if they assessed interventions to increase PrEP interest, uptake, or continuation among AGYW. Results were synthesized narratively. Of 2168 citations identified, 50 studies were eligible for inclusion, and 20 contained AGYW-specific data. Among cisgender and transgender AGYW, studies overall demonstrated a positive impact on PrEP interest and uptake but generally attained suboptimal continuation rates. Results demonstrate feasibility of deploying PrEP across diverse settings-particularly when interventions are layered, tailored to AGYW, and include differentiated delivery-but also highlight knowledge gaps and the need for more holistic metrics of success.

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.

'We Should Not Be Quiet but We Should Talk': Qualitative Accounts of Community-Based Communication of HIV Pre-Exposure Prophylaxis

Community leaders play an important role in the acceptance of public health services, but little is known about their willingness to facilitate HIV pre-exposure prophylaxis (PrEP) roll-out in Eswatini. We conducted in-depth interviews (n = 25) with purposefully selected male and female community leaders in Eswatini. We analysed our data inductively using a thematic analysis approach. Community leaders feel they are important communicators of culturally appropriate PrEP messaging. Our participants described a complex social space within their communities influenced by religion, tradition, values, and HIV stigma. Community leaders use their position to provide leverage for unique, effective, and easily accessible messages and platforms to reach the community in a manner that ensures trust, relatability, familiarity, and shared faith. Community leaders feel that they are trusted and see trust manifesting in the conversations they are able to engage in, and have a reach that extends beyond formal health services. Existing PrEP programming should embed community leader participation in PrEP programming and engage the trust, knowledge, and potential of community leaders to support PrEP uptake and acceptance.

Motivations for pre-exposure prophylaxis uptake and decline in an HIV-hyperendemic setting: findings from a qualitative implementation study in Lesotho

BACKGROUND

Pre-Exposure Prophylaxis (PrEP) has demonstrated clinical efficacy in preventing HIV infection, yet its uptake remains low. This study, conducted in five PrEP implementing districts in Lesotho, examined factors motivating persons at risk of HIV infection to adopt or reject PrEP when offered freely.

METHODS

In-depth interviews were undertaken with stakeholders directly engaged with PrEP policy (n = 5), program implementation (n = 4), and use (current PrEP users = 55, former PrEP users = 36, and PrEP decliners (n = 6)). Focus group discussions (n = 11, 105 total participants) were conducted with health staff directly providing HIV and PrEP services.

RESULTS

Demand for PrEP was reported highest among those at greatest risk for HIV acquisition: those in serodiscordant relationships and/or engaged in sex work. Culturally sensitive PrEP counseling was described as an opportunity to transfer knowledge, build trust, and address user concerns. Conversely, top-down counseling resulted in PrEP distrust and confusion about HIV status. Key motivations for PrEP uptake revolved around sustaining core social relationships, desire for safer conception, and caring for ailing relatives. The decline of PrEP initiation was driven by a combination of individual-level factors (risk perception, perceived side effects, disbelief of the drug's efficacy and PrEP's daily pill regimen), societal factors (lack of social support and HIV-related stigma), and structural factors related to PrEP access.

CONCLUSIONS

Our findings suggest strategies for effective national PrEP rollout and implementation include: (1) demand creation campaigns which highlight positive aspects of PrEP, while simultaneously addressing apprehensions for uptake; (2) strengthening health provider counseling capacity; and (3) addressing societal and structural HIV-related stigma.

PrEP uptake and persistence amongst HIV-negative women who exchange sex for money or commodities in Kampala, Uganda: A qualitative inquiry assessing the influence of pregnancy

Pregnant young women who exchange sex for money or commodities are at elevated biological and social risk for HIV acquisition. PrEP serves as an effective means of HIV prevention, including during pregnancy. This study aimed to explore attitudes, experiences and challenges with PrEP to understand what motivates or limits PrEP uptake and adherence specifically during pregnancy among this population of young women. Semi-structured interviews were conducted with 23 participants, recruited from the Prevention on PrEP (POPPi) study in the Good Health for Women Project clinic in Kampala, Uganda. POPPi's inclusion criteria comprised of HIV-uninfected women, aged 15-24, who exchange sex for money or commodities. Interviews focused on experience with PrEP and pregnancy. Data were analyzed utilizing a framework analysis approach. Key themes were comprised of participant barriers to and facilitators of PrEP uptake and adherence. Reasons for PrEP initiation included desire for autonomy and agency, mistrust of partners, and social support. Participants expressed challenges with initiating or sustaining their use of PrEP, including pregnancy, PrEP access and perceived or felt stigma. During pregnancy, participants' primary motivators for altering PrEP use were either understanding of PrEP safety for their baby or changes in perceptions of their HIV risk. Many of these factors were similar across participants who had experience with pregnancy and those who did not. This study highlights the importance of addressing barriers to and facilitators of PrEP uptake and persistence, especially during pregnancy where risk is elevated, with a multi-level approach. Community-oriented education, stigma reduction activities alongside access to PrEP, can serve as means for adherence. The development of robust PrEP support services and guidelines regarding PrEP use during pregnancy among high-risk women, and strategies for their implementation, are of utmost importance for the control of HIV in key populations and the elimination of mother-to-child transmission of HIV.

Optimizing the pipeline of multipurpose prevention technologies: opportunities across women's reproductive lifespans

HIV/AIDS and maternal mortality are the two leading causes of death among women of reproductive age in sub-Saharan Africa. A growing body of research investigates opportunities for multipurpose prevention technologies (MPTs) that prevent unintended pregnancy, HIV, and/or other sexually transmitted infections (STIs) with a single product. More than two dozen MPTs are currently in development, most of them combining contraception with HIV pre-exposure prophylaxis, with or without protection from other STIs. If successful, such MPTs could offer women benefits at multiple levels: greater motivation for effective use; lower product administration burden; accelerated integration of HIV, STI, and reproductive health services; and opportunities to circumvent stigma by using contraception as a "fig leaf" for HIV and/or STI prevention. However, even if women find respite from product burden, lack of motivation, and/or stigma in contraceptive-containing MPTs, their use of MPTs will be interrupted, often multiple times, over the reproductive lifecourse due to desire for pregnancy, pregnancy and breastfeeding, menopause, and changes in risk. Interruptions to the benefits of MPTs could be avoided by combining HIV/STI prevention with other life-stage-appropriate reproductive health products. New product concepts could include combining prenatal supplements with HIV and STI prevention, emergency contraception with HIV post-exposure prophylaxis, or hormone replacement therapies for menopause with HIV and STI prevention. Research is needed to optimize the MPT pipeline based on the populations underserved by available options and the capacity of resource-constrained health systems to deliver novel preventative healthcare products.

Trust in the provider and accurate self-reported PrEP adherence among adolescent girls and young women in South Africa and Zimbabwe: HPTN 082 study

BACKGROUND

Trust is an important cornerstone of patient-provider communication. Accurate reporting of pre-exposure prophylaxis (PrEP) adherence is vital for providers to determine who needs adherence support, especially adolescent girls and young women (AGYW) disproportionately affected by newly diagnosed HIV.

METHODS

This is a secondary analysis of the HPTN 082 open-label PrEP demonstration trial. From 2016-2018, 451 AGYW aged 16-25 years were enrolled in South Africa (Cape Town and Johannesburg) and Zimbabwe (Harare). PrEP was initiated by 427, and 354 (83%) had month three patient-reported adherence responses and intracellular tenofovir diphosphate (TFV-DP) measurements. The patient-reported adherence response to 'In the past month, how often did you take the tablet?' was dichotomized as 'high' if the response was every day or most days, and 'low' if some days or not many days or never. The biomarker marker evidence of adherence in dried blood spots was defined as 'high' if TFV-DP ≥ 700, and 'low' if < 350 fmol/punch. We used multinomial logistic regression to examine if trust in the PrEP provider was associated with concordance between patient-reported adherence and intracellular tenofovir-diphosphate (TFV-DP).

RESULTS

AGYW who reported trust in their providers were almost four-fold (aOR 3.72, 95% CI 1.20-11.51) more likely to have concordant adherence (high self-reported adherence and high TFV-DP concentrations) compared to discordant non-adherence (high self-reported adherence and low TFV-DP concentrations).

CONCLUSION

Education and training of providers to build trusting relationships with AGYW may lead to more accurate reporting of PrEP adherence. With accurate reporting, adequate support can be provided to bolster adherence.

Motivators for oral PrEP uptake and adherence in the eThekwini municipality, KwaZulu-Natal

Pre-exposure prophylaxis (PrEP) is a single daily pill that prevents a seropositive HIV status. Since 2016, South Africa has staggered PrEP roll-out, with uptake levels not reaching optimal goals. The aim of this study was to determine motivation behind PrEP initiation and adherence among South African users. A phenomenological qualitative study (n = 15) was used. Participants were purposively recruited from two primary healthcare clinics in eThekwini, KwaZulu-Natal. Thematic analysis was used to analyse the data. Three themes were identified: motivation for PrEP uptake, PrEP adherence and PrEP awareness. Initiation was influenced by healthcare professionals. Responsibility for one's well-being, serodiscordant relationships and sexual partner's behavioural patterns contributed toward initiation. Most were fully compliant, using reminders to negate medication forgetfulness. The internet and healthcare professionals served as information sources, however, few were aware of PrEP prior to this. Innovative ways are required to increase awareness levels and increase uptake.

Optimizing the vaginal microbiome as a potential strategy to reduce heterosexual HIV transmission

Bacterial vaginosis (BV) is a proinflammatory genital condition characterized by high vaginal bacterial diversity and a paucity of Lactobacillus species. BV has been linked to an elevated risk of HIV acquisition among HIV-negative women and of forward HIV transmission to male sex partners among women living with HIV (adjusted hazard ratios of 1.69 and 3.17, respectively), potentially by eliciting genital inflammation in women with BV and their male sex partners. BV is also highly prevalent among women in sub-Saharan Africa, suggesting that BV treatment may have potential as an HIV prevention strategy. BV is typically treated with antibiotics but recurrence rates are high, possibly because treatment does not directly promote Lactobacillus growth. More recently, BV treatment strategies incorporating live biotherapeutic lactobacilli have led to sustained optimization of the vaginal microbiome and a decrease in inflammatory biomarkers previously associated with HIV susceptibility. Future studies are urgently needed to evaluate BV treatment strategies that can optimize the vaginal microbiome in the long term through colonization with H₂ O₂ -producing vaginal lactobacilli and to assess whether vaginal microbiota optimization is able to reduce the risk of HIV transmission.

Multilevel Factors Influencing Interruptions in PrEP Use Among Young Women in Siaya County, Kenya

Young women in sub-Saharan Africa continue to be disproportionately at risk for HIV. Oral pre-exposure prophylaxis (PrEP) can reduce women's HIV risk when taken daily throughout their "seasons of risk". We used photovoice to describe community views on factors influencing interruptions in PrEP use among young cisgender women in Siaya County, Kenya. Through group discussions, young women taking PrEP and their social network members (female peers, male peers/partners, family, and community members) shared photographs and identified broad social-ecological causes of PrEP interruptions, including: (1) widespread misinformation about PrEP, (2) social pressures from religious communities, (3) health care staff recommendations to interrupt PrEP use, (4) partner rejection of PrEP, (5) changes in women's risk awareness, and (6) a personal desire to occasionally pause daily use. Collectively, participants identified strategies to address these challenges. These findings can inform future programs targeting the broader social-ecological influences on young women's persistent use of PrEP.

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

BACKGROUND

Pre-exposure prophylaxis (PrEP) is an emerging biomedical prevention intervention. Documenting PrEP service delivery models (SDMs) that promote linkage to and continuation of PrEP will inform guidelines and maximise roll-out.

OBJECTIVES

To synthesise and appraise the effectiveness and feasibility of PrEP SDMs designed to promote linkage to PrEP care among adolescent girls and young women (AGYW) and men in sub-Saharan Africa (SSA).

ELIGIBILITY CRITERIA

Primary quantitative and qualitative studies published in English and conducted in SSA were included. No restrictions on the date of publication were applied.

SOURCES OF EVIDENCE

Methodology outlined in the Joanna Briggs Institute reviewers' manual was followed. PubMed, Cochrane library, Scopus, Web of Science and online-conference abstract archives were searched.

CHARTING METHODS

Data on article, population, intervention characteristics and key outcomes was charted in REDCap.

RESULTS AND CONCLUSION

Of the 1204 identified records, 37 (met the inclusion criteria. Health facility-based integrated models of PrEP delivery with family planning, maternal and child health or sexual and reproductive services to AGYW resulted in PrEP initiation of 16%-90%. Community-based drop-in centres (66%) was the preferred PrEP outlet for AGYW compared with public clinics (25%) and private clinics (9%). Most men preferred community-based delivery models. Among individuals who initiated PrEP, 50% were men, 62% were <35 years old and 97% were tested at health fairs compared with home testing. Integrated antiretroviral therapy (ART)-PrEP delivery was favoured among serodiscordant couples with 82.9% of couples using PrEP or ART with no HIV seroconversions. PrEP initiation within healthcare facilities was increased by perceived client-friendly services and non-judgemental healthcare workers. Barriers to PrEP initiation included distance to travel to and time spent at health facilities and perceived community stigma. PrEP SDMs for AGYW and men need to be tailored to the needs and preferences for each group. Programme implementers should promote community-based SDMs to increase PrEP initiation among AGYW and men.

Psychosocial determinants of pre-exposure prophylaxis use among pregnant adolescent girls and young women in Cape Town, South Africa: A qualitative study

BACKGROUND

In South Africa, at least 7.5 million people (age ≥15 years) are living with Human Immunodeficiency Virus (HIV). In 2020, 220,000 new infections occurred, approximately one-third of which were among cisgender adolescent girls and women (age ≥15 years). The perspectives of pregnant adolescent girls and young women (AGYW) as key, targeted end-users of pre-exposure prophylaxis (PrEP) in this setting are not well known.

METHODS

We purposively recruited participants enrolled in an ongoing cohort study at an urban antenatal clinic in Cape Town, South Africa for in-depth interviews between July-September 2020. We restricted our analysis to pregnant AGYW (age: 16-25 years) who initiated daily oral PrEP (Tenofovir/Emtricitabine) antenatally and self-reported either high PrEP persistence (≥25 days in the past 30 days and no missed PrEP collection), or low PrEP persistence and/or discontinuation (missing >5 days in the last 30 days or missed PrEP collection). The findings were organized thematically, per the adapted Health Behavior Model (2000), using Nvivo-v.1.5.

RESULTS

We interviewed 18 AGYW (mean age = 22 years), at a mean of 14 weeks postpartum. Higher self-esteem and high-quality study provider-client relationships, including empathic psychosocial support, facilitated PrEP continuation. Reported barriers included unstable social structure characteristics (i.e., financial hardship) and individual factors (i.e., unintended pregnancy, parental rejection, and inadequate peer- and [non-cohabiting] partner support). Participants self-perceived a need for PrEP, feeling susceptible to non-consensual, forced sex, or considering partners' (presumed) sexual risk-taking. Limited community awareness regarding PrEP availability and/or perceived complexity in navigating health system access to PrEP, impede continuation.

CONCLUSIONS

PrEP-focused healthcare access pathways for pregnant and postpartum AGYW need to be simplified. Further research is needed on health system determinants (i.e., structural barriers, provider-client interactions, and related outcomes) of oral PrEP utilization. In 2022, South Africa announced regulatory approval of long-acting PrEP options (i.e., the dapivirine ring for non-pregnant women and injectable cabotegravir, respectively); these may mitigate implementation barriers reported in this study. However, the safety and efficacy of long-acting PrEP (e.g., injectables, implants) among pregnant or breastfeeding women, specifically, remains to be confirmed in this setting.

Development of a tool to assess HIV prevention readiness of adolescent girls and young women in HPTN 082 study

BACKGROUND

African adolescent girls and young women (AGYW) represent a large proportion of new HIV infections, a priority population for pre-exposure prophylaxis (PrEP), but adherence remains a challenge. A reliable, valid readiness tool would help identify AGYW motivated to take PrEP who need adherence support.

METHODS

In the HPTN 082 open-label PrEP study (2016-2019), South African and Zimbabwean women ages 16-25 were administered an HIV prevention readiness measure (HPRM). The 25 items in the HPRM included medication beliefs, connection with care, disclosure of PrEP use, social support, and housing stability using a 5-point Likert scale. Exploratory factor analysis (EFA) using polychoric correlations, scale reliability, and predictive validity were performed on data from 315 participants who responded to all items. We assessed the predictive value of HPRM scores with PrEP adherence, defined as tenofovir-diphosphate (TFV-DP) concentrations in dried blood spots, as a continuous measure and dichotomized as high PrEP adherence (≥700 fmol/punch).

RESULTS

EFA yielded 23 items with three subscales: self-efficacy (16 items), PrEP disclosure (4 items), and social support (3 items). Cronbach's α ranged from 0.71 to 0.92 for the overall scale and the subscales. The average overall scale and the subscales were predictive of 3-month PrEP adherence for TFV-DP concentrations: for each unit increase of the HPRM score, TFV-DP concentration increased by 103 fmol/punch (95% CI: 16, 189, p = 0.02); the highest HPRM score equated with 608 fmol/punch on average. For the self-efficacy subscale, TFV-DP increased by 90 fmol/punch (95% CI: 7, 172, p = 0.03); PrEP disclosure, 68 fmol/punch (95% CI: 19, 117 p = 0.01); and social support, 58fmol/punch (95% CI: 2, 113, p = 0.04). Higher PrEP disclosure suggests high adherence (OR 1.36, 95% CI: 1.00, 1.86, p = 0.05) and predicted persistent high adherence at both months three and six (OR: 1.50, 95% CI: 1.03, 2.21, p = 0.04).

CONCLUSIONS

The HPRM scale overall and the subscales individually demonstrated good internal consistency among African young women. PrEP disclosure subscale exhibiting significant association with persistent high PrEP adherence is an important finding for PrEP adherence support programs. Future work will assess replicability and expand self-efficacy and social-support subscales after item revision.

Barriers and facilitators to oral PrEP uptake among high-risk men after HIV testing at workplaces in Uganda: a qualitative study

BACKGROUND

Men in Uganda contribute significantly to new HIV infections annually yet PrEP uptake among them is low and those initiated are likely to discontinue usage. We explored the barriers and facilitators to PrEP uptake among high-risk men employed in private security services with negative HIV results after testing at workplaces in Uganda.

METHODS

An explorative qualitative study comprising in-depth participant interviews. Data were collected via telephone calls and manually analyzed by inductive content analysis.

RESULTS

Fifty-six (56) men participated, 27(48.21%) had heard about PrEP, and 29(51.79%) were willing to initiate it. Four categories emerged for the facilitators of PrEP uptake including the perceived need for HIV prevention, awareness creation, availability, and sexual freedom. Six categories emerged for the barriers to PrEP uptake. These were: Inaccessibility of PrEP services, Misinformation, Knowledge deficit, Medication-related barriers, Potential for increased risky sexual behavior, and Perceptions about PrEP use.

CONCLUSION

The findings suggest the need for healthcare providers to offer information regarding PrEP and HIV prevention services and mass sensitization campaigns to facilitate uptake. Participants recommend mass roll-out of PrEP to lower-level facilities and accessible pick-up points for men such as workplaces. The men also suggested the use of longer-acting PrEP modalities such as an injectable option or an option that is utilized specifically by the female partner. Finally, the stigma surrounding PrEP use could be reduced by the separation of PrEP and ART services at health facilities, or special pick-up days to reduce waiting times.

Multi-level Factors Driving Pre-exposure Prophylaxis Non-initiation Among Young Women at High Risk for HIV in Kenya

Few studies have focused on understanding pre-exposure prophylaxis (PrEP) non-initiation among young, high-risk women in sub-Saharan Africa. This study aimed to qualitatively explore why young women in Kenya at high-risk for HIV chose not to enroll in a PrEP adherence trial. We performed 40 semi-structured interviews with young high-risk women assessing concerns about PrEP and/or study participation. We also assessed community-level factors influencing decision-making around PrEP through 10 focus groups involving peers, young men, caregivers, and community leaders. Our qualitative data reflect the complexity of navigating barriers preventing PrEP initiation in settings where taking PrEP may be perceived as immoral behavior. Framed within the context of risk perception, the decision to start PrEP may run counter to the potential risk of losing support from one's community. Our findings suggest that approaches addressing social norms, while de-medicalizing HIV prevention services, are needed to further increase PrEP uptake among young Kenyan women.

Measuring Oral Pre-exposure Prophylaxis (PrEP) Continuation Through Electronic Health Records During Program Scale-Up Among the General Population in Zambia

HIV pre-exposure prophylaxis (PrEP) is being scaled-up in Zambia, but PrEP continuation data are limited by paper-based registers and aggregate reports. Utilization of Zambia's electronic health record (EHR) system, SmartCare, may address this gap. We analyzed individuals aged ≥ 15 years who initiated PrEP between October 2020 and September 2021 in four provinces in Zambia in SmartCare versus aggregate reports. We measured PrEP continuation using Kaplan-Meier survival analysis and Cox proportional hazards models. SmartCare captured 29% (16,791/58,010) of new PrEP clients; 49% of clients continued at one month, and 89% discontinued PrEP by February 2022. Women were less likely than men to discontinue PrEP (adjusted hazard ratio [aHR]: 0.89, 95% CI 0.86-0.92, z = - 6.99, p < 0.001), and PrEP clients aged ≥ 50 years were less likely to discontinue PrEP compared to clients 15-19 years (aHR: 0.53, 95% CI 0.48-0.58, z = - 13.04, p < 0.001). Zambia's EHR is a valuable resource for measuring individual-level PrEP continuation over time and can be used to inform HIV prevention programs.

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

Introduction

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

Methods

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

Results

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

Conclusion

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

Self-reported and pill count measures of adherence to oral HIV PrEP among female sex workers living in South-Western Uganda

Background

Female sex workers (FSWs) in Uganda are at high risk of HIV infection. Scaling up oral pre-exposure prophylaxis (PrEP) will reduce HIV incidence if high levels of adherence are maintained. This study evaluates PrEP adherence using clinic-based pill counts and self-reported measures, and factors associated with protective levels of adherence.

Methods

Participants were sex workers who had been taking PrEP for at least 5 months and were attending routine follow-up visits for PrEP care in fishing communities and along the Trans-African Highway. Participants who had a pill count showing at least 85% use since their last clinic visit and those who reported taking their PrEP every day in the last 5 months were categorised as having ‘protective adherence’. Spearman’s correlation and weighted kappa assessed the relationship between pill count and self-reported measures. Bivariate and multivariate logistic regression was used to determine factors associated with protective adherence as measured by pill count.

Results

We recruited 524 FSWs, with a median age of 29 years (IQR 23–35). Participants were recruited from fishing communities and Trans-African Highway towns (n = 297, 56.7%, and n = 227, 43.0%). Nearly three quarters (n = 372, 71.0%) of women were estimated to have protective adherence based on pill count (i.e., a pill count of >85%) and 50.4% by self-report in last 3 months. There was a strong positive association between self-reported measures and pill count measures (rest = 0.6453, 95% CI = 0.5924–0.6927) and a moderate agreement between self-reported measures and pill count measures, κ = 0.544 (95%CI = 0.4869–0.6011, p < 0.001).

Factors associated with protective adherence included being aged 35 years or older (aOR = 2.40, 95% CI = 1.17–4.86), living in a fishing community (aOR = 1.45, 95% CI = 0.62–3.38), and having an STI in last 3 months (aOR = 1.64, 95% CI = 1.07–2.49).

Conclusion

Our findings indicate that PrEP-experienced FSWs attending clinical follow-up visits reported high protective levels of oral pre-exposure prophylaxis, as measured by both pill count and self-reported measures, and a moderate agreement between pill count and self-reported measures.

Factors influencing adolescent girls and young women's uptake of community-based PrEP services following home-based HIV testing in Eastern Cape, South Africa: a qualitative study

Home-based service delivery has been used to improve access to HIV testing and antiretroviral initiation across sub-Saharan Africa, but it has yet to be leveraged to improve pre-exposure prophylaxis (PrEP) uptake. We interviewed 37 adolescent girls and young women (AGYW) in Eastern Cape, South Africa to explore why they chose to initiate PrEP or not following home-based HIV testing and referral for PrEP, and what influenced time to PrEP initiation. Participants reported that home visits provided a source of trusted information and a way to involve family members in their PrEP initiation decisions, motivating some to start PrEP. AGYW who initiated PrEP were more likely to qualitatively perceive themselves to be at high risk for HIV compared with those who never initiated PrEP. Integrating home-based HIV testing with PrEP education and referral may be a valuable way to reduce familial barriers and boost PrEP uptake among AGYW in South Africa. Trial registration: NCT03977181. Retrospectively registered on June 6, 2019.

Providers' Attitudes and Experiences with Pre-Exposure Prophylaxis Implementation in a Population-Based Study in Kenya and Uganda

Pre-exposure prophylaxis (PrEP) implementation is underway across sub-Saharan Africa. However, little is known about health care providers' experiences with PrEP provision in generalized epidemic settings, particularly outside of selected risk groups. In this study (NCT01864603), universal access to PrEP was offered to adolescents and adults at elevated risk during population-level HIV testing in rural Kenya and Uganda. Providers received training on PrEP prescribing and support from local senior clinicians. We conducted in-depth interviews with providers (n = 19) in four communities in Kenya and Uganda to explore the attitudes and experiences with implementation. Transcripts were coded and analyzed using interpretivist methods. Providers had heterogenous attitudes toward PrEP in its early implementation: some expressed enthusiasm, while others feared being blamed for "failures" (HIV seroconversions) if participants were nonadherent, or that offering PrEP would increase "immorality." Providers supported PrEP usage among HIV-serodifferent couples, whose mutual support for daily pill-taking facilitated harmony and protection from HIV. Providers reported challenges with counseling on "seasons of risk," and safely stopping and restarting PrEP. They felt uptake was hampered for women by difficulties negotiating with partners, and for youth by parental consent requirements. They believed PrEP continuation was hindered by transportation costs, stigma, pill burden, and side effects, and was facilitated by counseling, proactive management of side effects, and home/community-based provision. Providers are critical "implementation actors" in interventions to promote adoption of new technologies such as PrEP. Dedicated training and ongoing support for providers may facilitate successful scale-up.

Impact of community health worker intervention on PrEP knowledge and use in Rakai, Uganda: A mixed methods, implementation science evaluation

BACKGROUND

Effective models of support for HIV pre-exposure prophylaxis (PrEP) are needed for populations at elevated risk. In a hyperendemic Ugandan fishing community, PrEP counseling was provided through a situated Information, Motivation, and Behavioral Skills (sIMB)-based community health worker (CHW) intervention. We evaluated the intervention using a mixed-methods, implementation science design.

METHODS

We surveyed all community members aged 15-49 through the Rakai Community Cohort Study. We used multivariable logistic regressions with generalized estimating equations to estimate the intervention's effect on PrEP knowledge and utilization. To understand intervention experiences and mechanisms, we conducted 74 qualitative interviews with 5 informant types (clients, CHWs, program staff, community leaders, health clinic staff) and analyzed data using an iterative, deductive approach. A mobile phone application provided intervention process implementation data.

RESULTS

Individuals self-reporting receipt of the CHW intervention showed significantly higher PrEP knowledge (N = 1848, PRR: 1.10, 95% CI: 1.06-1.14, p = <.0001), PrEP ever use (N = 1176, PRR: 1.77, 95% CI: 1.33-2.36, p = <.0001), and PrEP current use (N = 1176, PRR: 1.86, 95% CI: 1.22-2.82, p = 0.0039) compared to those who did not. Qualitative findings attributed positive PrEP outcomes to CHW counseling and effective use of motivational interviewing skills by CHWs. Salient themes across the RE-AIM framework included support for the CHW intervention and PrEP across clients, community, and implementers. Mobile application data demonstrated consistent delivery of the PrEP module throughout implementation.

CONCLUSIONS

CHWs improved PrEP knowledge and use among clients in an HIV hyperendemic fishing community. Mixed-methods, implementation science evaluations can inform adaptation of similar PrEP implementation strategies.

Episodic Use of Pre-Exposure Prophylaxis Among Young Cisgender Women in Siaya County, Kenya

The concept "seasons of risk" promotes use of pre-exposure prophylaxis (PrEP) only during periods of HIV risk. PrEP guidelines are aligned on daily use in women having vaginal sex during a risk period, and daily use for 28 days after the last potential exposure is recommended. However, when starting a "season of risk," guidelines vary on "time to protection," and unknowns remain in pharmacological research on PrEP protection in this population. During our iterative research on PrEP persistence using photovoice and in-depth interviews, we identified an ineffective pattern of PrEP use based on current guidelines-that is, routine, episodic use-among young cisgender women (YCW) in Siaya County, Kenya. Through same-group (n = 33 participants) and mixed-group (n = 31 participants) photovoice activities with YCW taking PrEP and female peers, participants explained that YCW associate their HIV risk with the sexual behaviors of their male partners who frequently travel from home. PrEP is considered unnecessary when partners are away because of no perceived risk. YCW re-start PrEP on or around the day of their partners' return because of heightened risk perceptions. Among the YCW interviewed (n = 18), nearly all of their partners traveled for about 1 week to 1 month at a time; about one-third of these women reported stopping PrEP during their partners' absence and re-starting it soon before or immediately upon their partners' arrival home. Additional research is critically needed to better inform PrEP guidelines and the decisions adolescent girls and young women make on how to use PrEP based on their risk context. In the interim, counseling on current dosing guidance when stopping and re-starting PrEP within a "season of risk" is needed.

Understanding PrEP decision making among pregnant women in Lilongwe, Malawi: A mixed-methods study

INTRODUCTION

Pre-exposure prophylaxis (PrEP) is a promising tool for HIV prevention during pregnancy. With increasing rollout in antenatal settings, counselling strategies to help pregnant women make appropriate decisions about PrEP use are needed. Understanding women's motivations and concerns for PrEP use-and how these inform their decision making and feelings about the decision to start PrEP-are critical to inform these strategies.

METHODS

We conducted a convergent mixed-methods study from June 2020 to June 2021 in the context of a PrEP adherence support trial among HIV-negative pregnant women in Lilongwe, Malawi. Two hundred women completed a survey reporting their motivations and concerns about PrEP use, and their feelings about the decision to start PrEP (Decisional Regret Scale). Thirty women completed in-depth interviews to better understand the decision-making process, including motivations and concerns weighed in women's decision to use PrEP. Analyses comprised descriptive and bivariate statistics, thematic qualitative analysis, and integration of quantitative and qualitative results.

RESULTS

Women initiating PrEP during pregnancy were highly motivated to obtain HIV protection for themselves and their unborn child, often due to perceived HIV risk connoted by a recent sexually transmitted infection and/or concerns about partner non-monogamy. These motivations prevailed despite some concerns about safety and side effects, anticipated stigmatization, and concerns about adherence burden and pill attributes. Many women had informed their partner of their decision to use PrEP yet few felt their decision was contingent upon partner approval. Most women felt positively about the decision to start PrEP (mean decisional regret = 1.2 out of 5), but those with a greater number of concerns reported greater decisional regret (B = 0.036; p = 0.005). Furthermore, women who were specifically concerned about partner disclosure, who disliked pills or who had no perceived HIV risk reported greater decisional regret.

CONCLUSIONS

Pregnant women were strongly motivated by the promise of HIV protection offered by PrEP and accepted it despite diverse concerns. A shared decision-making approach that centres pregnant women and offers partner involvement may help identify and address initial concerns about PrEP use and support prevention-effective use of PrEP during this important period.

How gender norms and 'good girl' notions prevent adolescent girls and young women from engaging with PrEP: qualitative insights from Zimbabwe

BACKGROUND

Pre-exposure prophylaxis, or PrEP, has been hailed for its promise to provide women with user-control. However, gender-specific challenges undermining PrEP use are beginning to emerge. We explore the role of gender norms in shaping adolescent girls and young women's (AGYW) engagement with PrEP.

METHODS

We draw on qualitative data from 12 individual interviews and three focus group discussions with AGYW from eastern Zimbabwe. Interviews were transcribed and thematically coded in NVivo 12. Emerging themes were further investigated using Connell's notion of 'emphasised femininity'.

RESULTS

Participants alluded to the patriarchal society they are part of, with 'good girl' notions subjecting them to direct and indirect social control. These controls manifest themselves through the anticipation of intersecting sexuality- and PrEP-related stigmas, discouraging AGYW from engaging with PrEP. AGYW recounted the need for permission to engage with PrEP, forcing them to consider engaging with PrEP in secrecy. In addition, limited privacy at home, and fear of disclosure of their health clinic visits, further heightened their fear of engaging with PrEP. PrEP is not simply a user-controlled HIV prevention method, but deeply entrenched within public gender orders.

CONCLUSION

AGYW face significant limitations in their autonomy to initiate and engage with PrEP. Those considering PrEP face the dilemma of Scylla and Charybdis: The social risks of stigmatisation or risks of HIV acquisition. Efforts to make PrEP available must form part of a combination of social and structural interventions that challenge harmful gender norms.

Adaptation and psychometric evaluation of a scale to measure oral pre-exposure prophylaxis-related stigma among key and vulnerable populations in Kenya

INTRODUCTION

As oral pre-exposure prophylaxis (PrEP) services scale up throughout sub-Saharan Africa (SSA), clients continue to face challenges with sustained PrEP use. PrEP-related stigma has been shown to influence engagement throughout the HIV PrEP care continuum throughout SSA. Validated quantitative measures of PrEP-related stigma in SSA are of critical importance to better understand its impacts at each stage of the HIV PrEP care continuum. This study aimed to psychometrically evaluate a PrEP-related stigma scale for use among key and vulnerable populations in the context of a Kenya national PrEP programme.

METHODS

As part of a larger prospective cohort study nested within Kenya's Jilinde programme, this study used baseline data collected from 1135 participants between September 2018 and April 2020. We used exploratory factor analysis to evaluate the factor structure of a PrEP-related stigma scale. We also assessed convergent construct validity of the PrEP-Related Stigma Scale by testing for expected correlations with depression and uptake of HIV services. Finally, we examined the relationship between PrEP-related stigma and key demographic, psychosocial and behavioural characteristics.

RESULTS

We identified four dimensions of PrEP-related stigma: (1) interpersonal stigma, (2) PrEP norms, (3) negative self-image and (4) disclosure concerns. The scale demonstrated strong internal consistency (α = 0.84), was positively correlated with depressive symptoms and negatively correlated with uptake of HIV services. Multivariable regression analysis demonstrated associations between PrEP-related stigma and sex worker identity.

CONCLUSIONS

The adapted and validated PrEP-Related Stigma Scale can enable programmes to quantify how PrEP-related stigma and its dimensions may differentially impact outcomes on the HIV PrEP care continuum, evaluate stigma interventions and tailor programmes accordingly. Opportunities exist to validate the scale in other populations and explore further dimensions of PrEP-related stigma.

"I was still very young": agency, stigma and HIV care strategies at school, baseline results of a qualitative study among youth in rural Kenya and Uganda

INTRODUCTION

Adolescents and young adults living with HIV (AYAH) have the lowest rates of retention in HIV care and antiretroviral therapy (ART) adherence, partly due to the demands of school associated with this life stage, to HIV-related stigma and to fears of serostatus disclosure. We explore the implications of school-based stigma and disclosure on the development of agency during a critical life stage in rural Kenya and Uganda.

METHODS

We conducted a qualitative study in the baseline year of the SEARCH Youth study, a combination intervention using a life-stage approach among youth (15-24 years old) living with HIV in western Kenya and southwestern Uganda to improve viral load suppression and health outcomes. We conducted in-depth, semi-structured interviews in 2019 with three cohorts of purposively selected study participants (youth [n = 83], balanced for sex, life stage and HIV care status; recommended family members of youth [n = 33]; and providers [n = 20]). Inductive analysis exploring contextual factors affecting HIV care engagement revealed the high salience of schooling environments.

RESULTS

Stigma within school settings, elicited by non-consensual serostatus disclosure, medication schedules and clinic appointments, exerts a constraining factor around which AYAH must navigate to identify and pursue opportunities available to them as young people. HIV status can affect cross-generational support and cohort formation, as AYAH differ from non-AYAH peers because of care-related demands affecting schooling, exams and graduation. However, adolescents demonstrate a capacity to overcome anticipated stigma and protect themselves by selectively disclosing HIV status to trusted peers and caregivers, as they develop a sense of agency concomitant with this life stage. Older adolescents showed greater ability to seek out supportive relationships than younger ones who relied on adult caregivers to facilitate this support.

CONCLUSIONS

School is a potential site of HIV stigma and also a setting for learning how to resist such stigma. School-going adolescents should be supported to identify helpful peers and selectively disclose serostatus as they master decision making about when and where to take medications, and who should know. Stigma is avoided by fewer visits to the clinic; providers should consider longer refills, discreet packaging and long-acting, injectable ART for students.

Pre-Exposure Prophylaxis (PrEP) Initiation and Retention Among Young Kenyan Women

The DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, Safe) Initiative works to reduce HIV infection among adolescent girls and young women (AGYW) through prevention interventions including Pre-Exposure Prophylaxis (PrEP). Pamoja CBO in Kisumu, Kenya implemented DREAMS. We describe PrEP initiation and persistence in 549 AGYW who started PrEP through Pamoja and factors associated with discontinuation. Median persistence time was 308 days (95% CI 245, 382) with 59% of AGYW discontinuing by the end of the study. The most common reasons for stopping PrEP were lack of perceived risk (27.9%) and relocation (18.7%). In the multivariable model, only age < 18 was associated with stopping PrEP. Younger age was associated with shorter time to discontinuation. Implementing PrEP through DREAMS was successful in supporting initiation of PrEP for AGYW. However, low rates of persistence at 1 year emphasizes the need for strategies to support PrEP persistence if HIV elimination is to be achieved.

Condom failure and pre-exposure prophylaxis use experience among female sex workers in Ethiopia: a qualitative study

BACKGROUND

Female sex workers (FSW) remain a highly exposed group for HIV/STIs due to different factors including condom failure. In Ethiopia, pre-exposure prophylaxis (PrEP) has recently been introduced as an intervention strategy to prevent new HIV infections, but knowledge about FSWs' experiences of condom failure and PrEP use remains scarce. Therefore, this study explores FSWs' experiences concerning condom failure and their attitudes towards, and experiences of, PrEP uptake.

METHOD

A qualitative study using in-depth interviews was conducted among FSWs in Addis Ababa. A manifest and latent content analysis method was applied to identify categories and emerging themes.

RESULT

Seventeen FSWs (10 who started on PrEP, 1 who discontinued, and 6 who didn't start) were interviewed. FSWs described the reasons behind condom failure, the mechanisms they used to minimize the harm, and their attitudes towards PrEP use. FSWs struggled with the continuous risk of condom failure due to factors related to clients' and their own behavior. PrEP was mentioned as one the strategies FSWs used to minimize the harm resulting from condom failure, but PrEP use was compounded with doubts that deterred FSWs from uptake. FSWs' misconceptions, their lack of confidence, and PrEP side effects were also mentioned as the main challenges to start taking PrEP and/or to maintain good adherence.

CONCLUSION

The demands and behavior of the clients and FSWs' own actions and poor awareness were factors that increased the exposure of FSWs to condom failure. In addition, the challenges associated with PrEP uptake suggest the need for user-friendly strategies to counteract these barriers and facilitate PrEP uptake.

Oral pre-exposure prophylaxis preference, uptake, adherence and continuation among adolescent girls and young women in Kampala, Uganda: a prospective cohort study

Introduction

Oral pre‐exposure prophylaxis (PrEP) has been scaled up; however, data from real‐world settings are limited. We studied oral PrEP preference, uptake, adherence and continuation among adolescent girls and young women (AGYW) vulnerable to HIV in sub‐Saharan Africa.

Methods

We conducted a prospective cohort study among 14‐ to 24‐year‐old AGYW without HIV who were followed for 12 months in Kampala, Uganda. Within at least 14 days of enrolment, they received two education sessions, including demonstrations on five biomedical interventions that are; available (oral PrEP), will be available soon (long‐acting injectable PrEP and anti‐retroviral vaginal ring) and in development (PrEP implant and HIV vaccine). Information included mode and frequency of delivery, potential side effects and method availability. Volunteers ranked interventions, 1 = most preferred to 5 = least preferred. Oral PrEP was “preferred” if ranked among the top two choices. All were offered oral PrEP, and determinants of uptake assessed using Poisson regression with robust error variance. Adherence was assessed using plasma tenofovir levels and self‐reports.

Results

Between January and October 2019, 532 volunteers were screened; 285 enrolled of whom 265 received two education sessions. Mean age was 20 years (SD±2.2), 92.8% reported paid sex, 20.4% reported ≥10 sexual partners in the past 3 months, 38.5% used hormonal contraceptives, 26.9% had chlamydia, gonorrhoea and/or active syphilis. Of 265 volunteers, 47.6% preferred oral PrEP. Willingness to take PrEP was 90.2%; however, uptake was 30.6% (n = 81). Following enrolment, 51.9% started PrEP on day 14 (same day PrEP offered), 20.9% within 30 days and 27.2% after 30 days. PrEP uptake was associated with more sexual partners in the past 3 months: 2–9 partners (aRR = 2.36, 95% CI: 1.20–4.63) and ≥10 partners (aRR 4.70, 95% CI 2.41–9.17); oral PrEP preference (aRR 1.53, 95% CI 1.08–2.19) and being separated (aRR 1.55, 95% CI 1.04–2.33). Of 100 samples from 49 volunteers during follow up, 19 had quantifiable tenofovir levels (>10 μg/L) of which only three were protective (>40 μg/L).

Conclusions

Half of AGYW preferred oral PrEP, uptake and adherence were low, uptake was associated with sexual behavioural risk and oral PrEP preference. Development of alternative biomedical products should be expedited to meet end‐user preferences and, community delivery promoted during restricted movement.

Health Care Worker Perspectives of HIV Pre-exposure Prophylaxis Service Delivery in Central Uganda

Background

Scale-up of HIV pre-exposure prophylaxis (PrEP) services in Uganda is ongoing. However, health care workers (HCWs) may not be aware of PrEP nor what offering this service entails. We explored the impact of standardized HCW training on the knowledge and perspectives of PrEP service delivery in Uganda.

Methods

We recruited HCWs from facilities that offered HIV-related services in Central Uganda. Using the Uganda Ministry of Health curriculum, we trained HCWs on PrEP services. We collected data about PrEP knowledge, preparedness, and willingness to deliver PrEP to multiple key populations before the training, immediately after the training, and >6 months later (exit). We additionally conducted 15 qualitative interviews after the exit survey. Quantitative data were analyzed by Fisher exact test, while qualitative interview data were analyzed inductively.

Results

We recruited 80 HCWs from 35 facilities in urban (N = 24, 30%), peri-urban (N = 30, 37%), and rural (N = 26, 33%) areas. Most HCWs were nurse counselors (N = 52, 65%) or medical/clinical officers (N = 15, 18%). Surveys indicated that awareness of PrEP increased after the training and remained high. Knowledge of PrEP (i.e., as an effective, short-term antiretroviral medication to use before HIV exposure for people at high risk) generally increased with training, but significant gaps remained, and knowledge decreased with time. Most HCWs recommended PrEP for female sex workers and HIV serodifferent couples, as well as other key populations. We observed increases in the number of HCW who felt their facility was prepared to cater for HIV prevention and provide PrEP, but this view was not universal. HCWs believed in PrEP effectiveness and embraced it as an additional HIV prevention method. Concerns included patient adherence and behavioral risk compensation. HCWs noted challenges in PrEP delivery in terms of inadequate clinic preparedness, infrastructure, staff capacity, and poor attitudes toward key populations by untrained health workers. They felt further training was needed to ensure a smooth scale-up of services without stigmatization.

Conclusions

Standardized training improved knowledge, willingness, and preparedness to offer PrEP services among most HCWs in Central Uganda. Ongoing training will be needed to optimize PrEP delivery services and expand delivery to levels needed for population-level impact.

"I prefer to take pills when I plan to have sex": Perceptions of on-demand versus daily oral pre-exposure prophylaxis among adolescents in Kampala, Uganda

There is limited information about the use of on-demand and daily pre-exposure prophylaxis (PrEP) among adolescents and young people (AYP) in sub-Saharan Africa. We explored perceptions of both regimens among 14- to 19-year-olds perceived to be at high risk of HIV infection in Kampala, Uganda, using qualitative data collection methods. Data were analysed by theme and interpreted based on constructs from the framework of acceptability. Although there were no noticeable gender differences in preferences for a particular regimen, acceptability of PrEP depended on individual AYP sexual behaviour at the time of the study. Those who perceived themselves to be at increased risk of acquiring HIV preferred using daily PrEP, citing the consistency that comes from taking a pill daily and which they considered to be efficacious and safe. AYP who had less frequent sex preferred on-demand PrEP because it would enable them to "plan for sex". However, both groups perceived taking daily PrEP to be a burden, which was an impediment to acceptance of this form of PrEP. AYP anticipated that daily pill taking would be very stressful, requiring a lot of effort and would interrupt their daily routine. Therefore, while both on-demand and daily PrEP were acceptable and beneficial to these AYP, preferences for either regimen depended on self-perceived risk. Thus, oral PrEP use should be tailored to end-user preferences and risk profiles.

Antiretroviral therapy based HIV prevention targeting young women who sell sex: a mixed method approach to understand the implementation of PrEP in a rural area of KwaZulu-Natal, South Africa

Pre-Exposure Prophylaxis (PrEP) is a potential game-changer for HIV. We used PrEP introduction for Young Women Who Sell Sex (YWSS) in a rural South Africa district to understand community norms and PrEP coverage in YWSS. Between 2017 and 2018, we measured awareness and uptake of PrEP in a representative cohort of 2184 Adolescent Girls and Young Women (AGYW) aged 13-22. We conducted group discussions with young people and community members (19); key informant interviews (9), in-depth interviews with 15-24 year-olds (58) and providers (33). Interviews were analysed using thematic analysis. PrEP awareness increased from 2% to 9%. Among 965 AGYW sexually-active by 2018, 13.4% (95%CI: 11.4%-15.7%) reported transactional sex and 10.6% (95%CI: 8.85-12.7%) sex for money. Of the 194 YWSS, 21 were aware of PrEP, but none had used it. Youth were enthusiastic about PrEP as tool for HIV prevention; whilst older community members were cautious about a technology they had limited experience with but could benefit select groups. Teachers and healthcare providers were concerned that PrEP would lower personal responsibility for sexual health. In conclusion, the narrow and limited introduction of PrEP to YWSS reduced the accessibility and reach. Introducing PrEP as part of sexual healthcare may improve demand and access for YWSS.

Oral PrEP Consultations Among Adolescent Girls and Young Women in Kisumu County, Kenya: Insights from the DREAMS Program

Although Kenya nationally scaled up oral pre-exposure prophylaxis (PrEP) in May 2017, adolescent girls' (AG, aged 15-19 years) and young women's (YW, aged 20-24 years) PrEP use remains suboptimal. Thus, we analyzed PrEP consultations-interactions with a healthcare provider about PrEP-among Kenyan AGYW. In April-June 2018, AGYW enrolled in DREAMS in Kisumu County, Kenya self-reported their HIV-related knowledge, behaviors, and service use. Among HIV negative, sexually active AG (n = 154) and YW (n = 289), we examined associations between PrEP eligibility and PrEP consultations using prevalence ratios (PR, adjusted: aPR). Most AG (90.26%) and YW (94.12%) were PrEP-eligible due to inconsistent/no condom use, violence survivorship, or recent sexually transmitted infection symptoms. Between PrEP-eligible AG and YW, more YW were ever-orphaned (58.09%), ever-married (54.41%), ever-pregnant (80.88%), and out of school (78.31%); more PrEP-eligible YW reported PrEP consultations (41.18% vs. 24.46%, aPR = 1.51 [1.01-2.27]). AG who used PEP (post-exposure prophylaxis) reported more consultations (aPR = 5.63 [3.53-8.97]). Among YW, transactional sex engagers reported more consultations (58.62% vs. 39.09%, PR = 1.50 [1.06-2.12]), but only PEP use (aPR = 2.81 [2.30-3.43]) and multiple partnerships (aPR = 1.39 [1.06-1.82]) were independently associated with consultations. Consultations were lowest among those with 1 eligibility criterion (AG = 11.11%/YW = 27.18%). Comparatively, consultations were higher among AG and YW with 2 (aPR = 3.71 [1.64-8.39], PR = 1.60 [1.07-2.38], respectively) or ≥ 3 (aPR = 2.51 [1.09-5.78], PR = 2.05 [1.42-2.97], respectively) eligibility criteria. Though most AGYW were PrEP-eligible, PrEP consultations were rare and differed by age and vulnerability. In high-incidence settings, PrEP consultations should be conducted with all AGYW. PrEP provision guidelines must be re-assessed to accelerate AGYW's PrEP access.

Introducing the Dapivirine Vaginal Ring in Sub-Saharan Africa: What Can We Learn from Oral PrEP?

Purpose of review

Clinical trials have found that the dapivirine vaginal ring (DVR) is safe to use and effective at reducing women’s risk of acquiring HIV infection. As countries prepare for the introduction of this novel long-acting, woman-controlled prevention method, an examination of key learnings from oral pre-exposure prophylaxis (PrEP) delivery will help programs leverage successful innovations and approaches to support DVR scale-up and expand the method mix for HIV prevention.

Recent findings

Intensive efforts over the past 5 years have yielded lessons on how to facilitate access to oral PrEP; expand service delivery for PrEP; address the knowledge, attitudes, and skills providers need to support PrEP initiation and effective use; develop messaging that builds community and partner support and combats stigma; and understand the cyclical nature of PrEP use.

Summary

Evidence from oral PrEP introduction and scale-up can help inform and expedite DVR introduction.

A one-stop shop model for improved efficiency of pre-exposure prophylaxis delivery in public clinics in western Kenya: a mixed methods implementation science study

INTRODUCTION

In public clinics in Kenya, separate, sequential delivery of the component services of pre-exposure prophylaxis (PrEP) (e.g. HIV testing, counselling, and dispensing) creates long wait times that hinder clients' ability and desire to access and continue PrEP. We conducted a mixed methods study in four public clinics in western Kenya to identify strategies for operationalizing a one-stop shop (OSS) model and evaluate whether this model could improve client wait time and care acceptability among clients and providers without negatively impacting uptake or continuation.

METHODS

From January 2020 through November 2020, we collected and analysed 47 time-and-motion observations using Mann-Whitney U tests, 29 provider and client interviews, 68 technical assistance reports, and clinic flow maps from intervention clinics. We used controlled interrupted time series (cITS) to compare trends in PrEP initiation and on-time returns from a 12-month pre-intervention period (January-December 2019) to an 8-month post-period (January-November 2020, excluding a 3-month COVID-19 wash-out period) at intervention and control clinics.

RESULTS

From the pre- to post-period, median client wait time at intervention clinics dropped significantly from 31 to 6 minutes (p = 0.02), while median provider contact time remained around 23 minutes (p = 0.4). Intervention clinics achieved efficiency gains by moving PrEP delivery to lower volume departments, moving steps closer together (e.g. relocating supplies; cross-training and task-shifting), and differentiating clients based on the subset of services needed. Clients and providers found the OSS model highly acceptable and additionally identified increased privacy, reduced stigma, and higher quality client-provider interactions as benefits of the model. From the pre- to post-period, average monthly initiations at intervention and control clinics increased by 6 and 2.3, respectively, and percent of expected follow-up visits occurring on time decreased by 18% and 26%, respectively; cITS analysis of PrEP initiations (n = 1227) and follow-up visits (n = 2696) revealed no significant difference between intervention and control clinics in terms of trends in PrEP initiation and on-time returns (all p>0.05).

CONCLUSIONS

An OSS model significantly improved client wait time and care acceptability without negatively impacting initiations or continuations, thus highlighting opportunities to improve the efficiency of PrEP delivery efficiency and client-centredness.
