Acceptability of HIV self-testing in African students: a cross-sectional survey in the Democratic Republic of Congo

Factors Influencing the Acceptability and Uptake of HIV Self-Testing Among Priority Populations in Sub-Saharan Africa: A Scoping Review

Objectives

To identify and synthesize the factors influencing the acceptability and uptake of HIV self-testing (HIVST) among Priority Populations (PPs) in Sub-Saharan Africa (SSA) through a comprehensive scoping review.

Methods

Using Arksey and O'Malley's framework refined by Levac, we systematically reviewed the literature on factors affecting HIVST uptake and acceptability among PPs in SSA. The review included searches in six databases (Embase, Medline (via Ovid), PubMed, PsycINFO, Web of Science, WHO Global Health Library), as well as grey literature, including (Google Scholar and OpenGrey), limiting publications to 2010-2023.

Results

The review found evidence indicating that HIVST is widely accepted and considered convenient among priority groups. Key challenges include limited post-test counseling and linkage to care, which hinder effective implementation. Peer-led and digital distribution strategies show the potential to increase uptake. However, user errors and economic constraints pose significant barriers to scaling HIVST, underscoring the need for targeted interventions to address these implementation challenges for optimal impact.

Conclusion

While HIVST can boost testing rates among PPs in SSA, overcoming access and utilization barriers is crucial. Interventions addressing economic, educational, and systemic challenges are essential for successful HIVST integration into broader HIV prevention and care efforts.

Feasibility of HIV self-test implementation among Mizo youths: a field investigation from Northeast India bordering Myanmar

Introduction

This study investigated the potential of HIV self-test (HIVST) to reach individuals who otherwise might not access testing or antiretroviral therapy (ART). The study had two main objectives: (a) to develop an HIV self-test implementation plan based on the findings from qualitative inquiries with local stakeholders and (b) to examine HIVST uptake among youths in the urban setting of Aizawl district in Mizoram.

Methodology

In the first phase, qualitative in-depth interviews (IDI) were conducted with HIV program officials, religious leaders, community influencers, youths, and key population groups. These inquiries guided the planning of strategic communication, community engagement, HIVST delivery, and linkages with HIV confirmatory testing services in phase two. Factors associated with the non-uptake of HIV confirmatory tests by youths following HIVST were analyzed quantitatively. Additionally, secondary data collected from attendees of the "Integrated Counselling and Testing Centre" (ICTC) were also analyzed.

Results

The in-depth interviews underscored the need to introduce HIVST among Mizo youths. The respondents emphasized the importance of diverse outreach approaches and communication strategies, including the use of social media platforms, as critical components for successful HIVST implementation. They also provided valuable insights on the optimal locations and methods for making HIVST kits accessible. Among the youths who used HIVST, the majority were first-time testers (1,772/2,101; 84.3%). Those diagnosed with an undiagnosed HIV infection were started on ART. The preference for the blood-based HIVST format (1,162/2101; 55%) was noted to be slightly higher than the saliva-based format. Confirmatory test uptake was significantly higher among those with sero-reactive HIVST results (χ 2 23.89; p < 0.001). Factors independently associated with (adjusted odds ratio; AOR with 95% CI) "no-show for HIV confirmatory tests," which hold significant programmatic implications, included "age > 20 years (1.47; 1.18-1.82)," "gender (men)" (1.25; 1.01-1.55), "education below 10th standard" (5.16; 2.66-10.01), "no prior HIV testing experience" (2.12; 1.61-2.81), and "unwillingness to undergo HIV confirmatory testing" (2.85; 2.05-3.96). Individuals who opted for the blood-based HIVST were 23% less likely (AOR 0.77; 95% CI; 0.62-0.96) to drop out of the HIV confirmatory testing process. Additionally, only 1% of respondents perceived HIVST as having self-harm potential.

Conclusion

Sustained community engagement, effective networking with HIV program officials, and strategic communication were three critical pillars supporting the successful implementation of HIVST. There was a significant increase in HIVST uptake among young first-time testers.

Acceptability and use of HIV self-testing among young people in sub-Saharan Africa: a mixed methods systematic review

BACKGROUND

Young people (YP) are disproportionately affected by the HIV pandemic in sub-Saharan Africa (SSA), but testing rates remain low despite global targets of testing 95% of people with HIV infection by 2030. HIV self-testing (HIVST) has been recently introduced to reach high-risk population groups such as these. Thus, synthesis of emerging evidence on the acceptability and use of HIVST among YP in SSA is needed so that comprehensive information can be generated to inform policy and practice.

METHODS

We employed a mixed methods systematic review of quantitative and qualitative literature reporting on HIVST among YP involving any design and published in English by 31st of October 2023. The review synthesized quantitative evidence on acceptability and use of HIVST, and qualitative evidence on perspectives of YP about HIVST. We searched databases of published articles (e.g. MEDLINE, CINAHL) and Gray literature sources (e.g. Google, Google Scholar). The concepts for the search included self-testing, HIV/AIDS, and countries in SSA. Two authors independently screened, retrieved full-text, and assessed quality of the studies.

RESULTS

A total of 4150 studies were retrieved and 32 studies were finally included in the review. Acceptability of HIVST computed from a single item asking YP on their preference or willingness or demand for HIVST was moderate (34-67%) to high (≥ 67%) among YP in SSA. Nine of the fourteen studies that reported on acceptability found high acceptability of HIVST. Use of HIVST ranged from 0.8 to 100% while in most studies the use rate was below 50%. Key barriers to HIVST use were coping with a positive test in the absence of counselling and support, physical discomfort, and cost of kits. Perceived enablers included perceptions of HIVST as promoting personal empowerment and autonomy; privacy and confidentiality; and convenience in location, time, and skill.

CONCLUSIONS

HIVST was highly accepted but not well utilized among YP in SSA. YP showed diversified needs with mixed preferences for location, and modalities of service provision. Overall, the review identified heterogeneous evidence in terms of methods, population, outcome measures, and results. The review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO: ID = CRD42021278919).

Costs and scale-up costs of community-based Oral HIV Self-Testing for female sex workers and men who have sex with men in Jakarta and Bali, Indonesia

BACKGROUND

The proportion of individuals who know their HIV status in Indonesia (66% in 2021) still remains far below the first 95% of UNAIDS 2030 target and were much lower in certain Key Populations (KPs) particularly Female Sex Workers (FSW) and Male having Sex with Male (MSM). Indonesia has implemented Oral HIV Self-testing (oral HIVST) through Community-based screening (HIV CBS) in addition to other testing modalities aimed at hard-to-reach KPs, but the implementation cost is still not analysed. This study provides the cost and scale up cost estimation of HIV CBS in Jakarta and Bali, Indonesia.

METHODS

We estimated the societal cost of HIV CBS that was implemented through NGOs. The HIV CBS's total and unit cost were estimated from HIV CBS outcome, health care system cost and client costs. Cost data were presented by input, KPs and areas. Health care system cost inputs were categorized into capital and recurrent cost both in start-up and implementation phases. Client costs were categorized as direct medical, direct non-medical cost and indirect costs. Sensitivity and scenario analyses for scale up were performed.

RESULTS

In total, 5350 and 1401 oral HIVST test kits were distributed for HIV CBS in Jakarta and Bali, respectively. Average total client cost for HIV CBS Self testing process ranged from US$1.9 to US$12.2 for 1 day and US$2.02 to US$33.61 for 2 days process. Average total client cost for HIV CBS confirmation test ranged from US$2.83 to US$18.01. From Societal Perspective, the cost per HIVST kit distributed were US$98.59 and US$40.37 for FSW and MSM in Jakarta andUS$35.26 and US$43.31 for FSW and MSM in Bali.

CONCLUSIONS

CBS using oral HIVST approach varied widely along with characteristics of HIV CBS volume and cost. HIV CBS was most costly among FSW in Jakarta, attributed to the low HIV CBS volume, high personnel salary cost and client cost. Future approaches to minimize cost and/or maximize testing coverage could include unpaid community led distribution to reach end-users, integrating HIVST into routine clinical services via direct or secondary distribution and using social media network.

Acceptability and feasibility of HIV self-testing in Southeast Asia: A scoping review

BACKGROUND

HIV self-testing (HIVST) policies in Southeast Asia are under development. This scoping review aimed to systematically synthesize the available literature on the acceptability and feasibility of HIVST in Southeast Asia.

METHODS

Systematic search was conducted on January 20, 2022, in eight databases: PubMed/MEDLINE, CINAHL, Web of Science, Academic Search Complete, SocINDEX, PsycINFO, PsycArticles, and CENTRAL. Acceptability (HIV testing frequency, willingness to pay, use, and recommend the test, ease of use, preference over standard tests, and partner testing) and feasibility (error rate, readability, and diagnostic performance) parameters were followed for the inclusion of articles. A narrative synthesis was done to present findings from included studies on the acceptability and feasibility of HIVST.

RESULTS

A total of 5091 records were identified through database search, and 362 were deleted after deduplication. The screening process resulted in 18 studies that met the inclusion criteria. Results indicated a high acceptability rate due to convenience, increasing awareness about HIVST, availability, and affordability of test kits, and confidentiality of test results. A high feasibility rate was reported due to a low occurrence of errors in self-testing, interpretability of results, and a low percentage of invalid and false-reactive results. Issues identified include costs of HIVST for individual use, distribution mode, type of supervision, counseling, geographic location, and socioeconomic status.

CONCLUSIONS

Evidence supports the acceptability and feasibility of HIVST in Southeast Asia. There is a need to regulate and license HIVST in Southeast Asia to have better recognition as a supplement to HTS.

Awareness of and willingness to use oral HIV self-test kits among Kenyan young adults living in informal urban settlements: a cross-sectional survey

Self-administered HIV testing may be a promising strategy to improve testing in hard-to-reach young adults, provided they are aware of and willing to use oral HIV self-testing (HIVST). This study examined awareness of and willingness to use oral HIVST among 350 high-risk young adults, aged 18-22, living in Kenya's informal urban settlements. Bivariate and multivariate logistic regressions were used to examine differences in HIVST awareness and willingness by demographic and sexual risk factors. Findings showed that most participants were male (56%) and less than 20 years old (60%). Awareness of oral HIVST was low (19%). However, most participants (75%) were willing to use an oral HIV self-test in the future and ask their sex partner(s) to self-test before having sex (77%). Women (OR = 1.80, 95%CI:1.11, 2.92), older participants (aged 20+) (OR = 2.57, 95% CI:1.48, 4.46), and more educated participants (OR = 2.25, 95%CI:1.36, 3.70) were more willing to use HIVST as compared to men, teen-aged, and less educated participants, respectively. Young adults who reported recent engagement in high-risk sexual behaviors, such as unprotected sex, sex while high or drunk, or sex exchange, were significantly less likely to be willing to use an oral HIV self-test kit (OR = 0.34, 95%CI:0.13,0.86). Those with the highest monthly income (OR = 0.47, 95%CI: 0.25, 0.89) were also less willing to use HIVST. More community- and peer-based efforts are needed to highlight the range of benefits of HIVST (i.e., social, clinical, and structural) to appeal to various youth demographics, in addition to addressing concerns relating to HIVST.

Factors associated with HIV self-testing among female university students in Uganda: a cross-sectional study

BACKGROUND

Adolescent girls and young women (AGYW) at institutions of higher learning are at high risk of HIV, and conventional HIV testing services may not reach them sufficiently. HIV self-testing (HIVST) scalability can be informed by identifying AGYW who have used or are interested in using HIVST. We aimed to determine factors associated with use and willingness to use HIVST among female university students.

METHODS

An online cross-sectional survey was conducted among 483 female students at Makerere University, Uganda. Proportions of students who have used or are willing to use HIVST and their associated factors were determined. Modified Poisson regression models were used to estimate prevalence ratios (PR) and their 95% confidence intervals (CI).

RESULTS

The median age of the participants was 22 (Interquartile range [IQR] 21-23) years, and 21% had never tested for HIV. Over 93% were willing to utilize HIVST, and 19% had ever used HIV self-test kits. Increasing age (adjusted prevalence ratio [aPR] 1.23 per year, 95% CI 1.07-1.43) was significantly associated with HIVST use. Predictors of willingness to self-test for HIV were college type (arts vs. science-based, aPR 0.92, 95% CI 0.88-0.97), number of sexual partners (one, aPR 1.07, 95% CI 1.03-1.12 or ≥ 2, aPR 1.08, 95% CI 1.04-1.19, vs. none), alcohol (aPR 1.04, 95% CI: 1.00-1.09) or injection drug (aPR 1.04, 95% CI 1.00-1.09) use, a history of sexually transmitted infections in past 12 months (aPR 1.05, 95% CI 1.01-1.09), and HIV testing experience (tested in past 12 months, aPR 1.12, 95% CI 1.02-1.22 or over 12 months, aPR 1.13, 95% CI 1.03-1.24, vs. never tested).

CONCLUSION

HIVST was highly acceptable despite its limited use. This study demonstrates female student characteristics that can be leveraged to scale up HIVST programs in higher institutions of learning.

Assessment of knowledge and acceptability of HIV self-testing among students of selected universities in southwest Nigeria: an online cross-sectional study

Introduction

in Nigeria, it was estimated that 1.9 million people were living with HIV of which 130,000 people were newly infected with HIV. HIV self-testing would potentially increase access to HIV testing for people to know their status, get diagnosed, and initiate treatment as soon as possible. Our study aims to assess the knowledge of HIV Self-Testing (HIVST) and the acceptability of this youth-friendly approach among students in southwest Nigeria online.

Methods

a cross-sectional study was conducted among bona fide undergraduate students (2019/2020 session) of two popular tertiary institutions in southwest Nigeria. An online standardized self-administered questionnaire was administered using Google Forms. Microsoft Excel and IBM SPSS statistics were used for tabulation and statistical data analysis. The Chi-Square test was conducted using a P value of 0.05 to determine the level of significance.

Results

of the 155 students that participated in the study, 82 (52.9%) were male. Most of the respondents (65.2%) were studying medicine and other health-related courses. The mean knowledge of HIVST among respondents was slightly above average. Respondents studying medical and other health-related courses showed a slightly better level of knowledge than others although not statistically significant (P = 0.222). 76.1% of respondents had never used the HIVST option before and 62.6% are willing to use it sometimes in the future.

Conclusion

to achieve the UNAIDS 95-95-95 fast-track targets in Nigeria by 2030, there is a need to promote sexual and reproductive health education and increase awareness and accessibility of HIVST to youths.

Effectiveness of linkage to care and prevention interventions following HIV self-testing: a global systematic review and meta-analysis protocol

INTRODUCTION

Early identification of persons living with HIV (PLWH) is crucial to institute timely treatment to prevent HIV-related morbidity and mortality. The convenience, flexibility and confidentiality of HIV self-testing enhance the acceptability of HIV testing and early detection of PLWH. However, persons who tested positive after a self-test are more likely to present late for treatment. This review seeks to evaluate the effectiveness of interventions to improve linkage to care and prevention after self-testing.

METHODS AND ANALYSIS

We will search PubMed, Embase, Web of Science, Cochrane Library, PsycInfo, Global Health Library, ClinicalTrials.gov and current controlled trials for all randomised and non-randomised studies published from 1 January 2010 to 31 July 2022 without language restriction. Two review authors will independently screen and select articles (based on the eligibility criteria for this review), extract data and assess the risk of bias in the included studies. Study-specific estimates will be converted to log risk ratios and weighted by the inverse of the variance of the log risk ratio before pooling into a fixed-effect model. The Cochrane's Q χ2 test and the I2 statistic will be used to assess and quantify heterogeneity in the included studies, respectively. The Egger's test and funnel plots will be used to assess publication bias. Sensitivity analysis will be conducted using leave-one-out analysis to assess the impact of outliers on the overall summary intervention effect.

ETHICS AND DISSEMINATION

No ethical clearance is needed for the current study as it will be based on already published articles. We will publish the findings of this study in international peer-reviewed journals and present them at conferences.

Self-care interventions for sexual and reproductive health in humanitarian and fragile settings: a scoping review

BACKGROUND

Self-care is the ability of individuals, families, and communities to promote health, prevent disease, maintain health, and manage illness and disability with or without a health care provider. In resource-constrained settings with disrupted sexual and reproductive health (SRH) service coverage and access, SRH self-care could play a critical role. Despite SRH conditions being among the leading causes of mortality and morbidity among women of reproductive age in humanitarian and fragile settings, there are currently no reviews of self-care interventions in these contexts to guide policy and practice.

METHODS

We undertook a scoping review to identify the design, implementation, and outcomes of self-care interventions for SRH in humanitarian and fragile settings. We defined settings of interest as locations with appeals for international humanitarian assistance or identified as fragile and conflict-affected situations by the World Bank. SRH self-care interventions were described according to those aligned with the Minimum Initial Services Package for Reproductive Health in Crises. We searched six databases for records using keywords guided by the PRISMA statement. The findings of each included paper were analysed using an a priori framework to identify information concerning effectiveness, acceptability and feasibility of the self-care intervention, places where self-care interventions were accessed and factors relating to the environment that enabled the delivery and uptake of the interventions.

RESULTS

We identified 25 publications on SRH self-care implemented in humanitarian and fragile settings including ten publications on maternal and newborn health, nine on HIV/STI interventions, two on contraception, two on safe abortion care, one on gender-based violence, and one on health service provider perspectives on multiple interventions. Overall, the findings show that well-supported self-care interventions have the potential to increase access to quality SRH for crisis-affected communities. However, descriptions of interventions, study settings, and factors impacting implementation offer limited insight into how practical considerations for SRH self-care interventions differ in stable, fragile, and crisis-affected settings.

CONCLUSION

It is time to invest in self-care implementation research in humanitarian settings to inform policies and practices that are adapted to the needs of crisis-affected communities and tailored to the specific health system challenges encountered in such contexts.

Understanding factors that promote uptake of HIV self-testing among young people in Nigeria: Framing youth narratives using the PEN-3 cultural model

It is important to understand how to frame the formats for promoting HIV self-testing to increase uptake among young people. In this study, we used a culture-centered model to understand the narratives of HIV self-testing preferences among young people in Nigeria. We conducted a crowdsourcing contest to solicit ideas surrounding HIV self-testing promotion among young people (10–24 years) in Nigeria from October to November 2018 as part of the 2018 World AIDS Day event. We received 903 submissions and employed thematic content analysis to evaluate 769 eligible youth narratives. Thematic content analysis of the statements from the youth narratives was guided by the PEN-3 cultural model to examine the positive, existential, and negative perceptions (beliefs and values), enablers (resources), and nurturers (roles of friends and family) of HIV self-testing promotion among young people in Nigeria. Several themes emerged as factors that influence the uptake of HIV self-testing among young people in Nigeria. Specifically, seven themes emerged as perceptions: HIV testing accessibility, stigma reduction, and autonomy (positive); HIV self-testing kit packaging and advertisements (existential); lack of knowledge and increased stigma (negative). Seven themes emerged as enablers: social media, school, and government promotion (positive); gamification and animation (existential); high cost and access to linkage to care services (negative); And seven themes emerged as nurturers: peer, families, and faith-based communities (positive); parents and family-centered approach (existential); and partners and family (negative). Our data suggests that increased awareness around HIV self-testing on current youth-friendly platforms, de-stigmatization of HIV and HIV self-testing, decreased prices for HIV self-testing kits, reliability of testing kits, increased linkage to care services, and promotion of self-testing among family members and the community will be beneficial for HIV self-testing scale-up measures among young people in Nigeria.

Association between socio-economic factors and HIV self-testing knowledge amongst South African women

Background

Self-testing for HIV is an effective and alternative method of increasing HIV testing rates and a strategy for reaching populations that are underserved by HIV testing services. Nonetheless, many resource-constrained settings are yet to adopt HIV self-testing (HIVST) into their national HIV programmes.

Objectives

This study aimed to examine the association between socio-economic factors and HIVST knowledge amongst South African women.

Method

We used nationally representative data from the 2016 South African Demographic and Health Survey. A sample of 8182 women of reproductive age was analysed. The outcome variable was HIVST knowledge. This was measured dichotomously; know versus do not know about HIVST. The multivariable logistic model was used to examine the measures of association, with the level of significance set at P < 0.05.

Results

The prevalence rate of HIVST knowledge was found to be approximately 24.5% (95% confidence interval [CI]: 22.9–26.1) amongst South African women. Women with tertiary education were 3.93 times more likely to have HIVST knowledge, when compared with those with no formal education (odds ratio [OR]: 3.93; 95% CI: 1.37–11.26). Rural residents had a 33% reduction in HIVST knowledge when compared with those residing in urban areas (OR: 0.67; 95% CI: 0.51–0.89). The odds of interaction between the richer and richest women who have good knowledge of HIV infection were 1.88 and 2.24 times more likely to have HIVST knowledge, respectively, when compared with those from the poorest wealth household who have good knowledge of HIV infection.

Conclusion

Based on the low level of HIVST knowledge, the findings emphasise the importance of developing effective HIVST educational campaigns. Moreover, programmes should be designed to address the unique needs of the socio-economically disadvantaged women.

High Acceptance and Completion of HIV Self-testing Among Diverse Populations of Young People in Kenya Using a Community-Based Distribution Strategy

Oral HIV self-testing (HIVST) may expand access to testing among hard-to-reach reach adolescents and young adults (AYA). We evaluated community-based HIVST services for AYA in an urban settlement in Kenya. Peer-mobilizers recruited AYA ages 15-24 through homes, bars/clubs, and pharmacies. Participants were offered oral HIVST, optional assistance and post-test counseling. Outcomes were HIVST acceptance and completion (self-report and returned kits). Surveys were given at enrollment, post-testing, and 4 months. Log-binomial regression evaluated HIVST preferences by venue. Among 315 reached, 87% enrolled. HIVST acceptance was higher in bars/clubs (94%) than homes (86%) or pharmacies (75%). HIVST completion was 97%, with one confirmed positive result. Participants wanted future HIVST at multiple locations, include PrEP, and cost ≤ $5USD. Participants from bars/clubs and pharmacies were more likely to prefer unassisted testing and peer-distributers compared to participants from homes. This differentiated community-based HIVST strategy could facilitate engagement in HIV testing and prevention among AYA.

Implementation of a campus-based and peer-delivered HIV self-testing intervention to improve the uptake of HIV testing services among university students in Zimbabwe: the SAYS initiative

Background

The uptake of HIV testing services among adolescents and young adults in Zimbabwe is low due to stigma associated with the risk of mental and social harm. The WHO recommends HIV self-testing (HIVST) as an innovative approach to improve access to HIV testing for this hard-to-reach populations. This study describes the development and implementation of a coordinated multifaceted and multidisciplinary campus-based approach to improve the uptake of HIV testing among university students in Zimbabwe.

Methods

We utilized both quantitative and qualitative methods guided by the Exploration, Preparation, Implementation, and Sustainment Framework. A formative survey, in-depth interviews, and a scoping review were conducted as part of the situation analysis. Implementers (peer educators and health workers) were trained and community dialogue sessions were conducted to ascertain the determinants (enablers and barriers) influencing both the inner and outer contexts. Self-test kits were disbursed over 6 months before a summative evaluation survey was conducted. Qualitative data were analyzed thematically while the chi-squared test was used to analyze quantitative data.

Results

The formative evaluation showed that 66% of students intended to test and 44% of the enrolled students collected HIVST test kits. Giving comprehensive and tailored information about the intervention was imperative to dispel the initial skepticism among students. Youth-friendly and language-specific packaging of program materials accommodated the students. Despite the high acceptability of the HIVST intervention, post-test services were poorly utilized due to the small and isolated nature of the university community. Implementers recommended that the students seek post-test services off-site to ensure that those with reactive results are linked to treatment and care.

Conclusions

Peer-delivered HIVST using trained personnel was acceptable among adolescents and young adults offered the intervention at a campus setting. HIVST could increase the uptake of HIV testing for this population given the stigma associated with facility-based HTS and the need for routine HIV testing for this age group who may not otherwise test. An off-site post-test counseling option is likely to improve the implementation of a campus-based HIVST and close the linkage to treatment and care gap.

Law, human rights and gender in practice: an analysis of lessons from implementation of self-care interventions for sexual and reproductive health

Self-care interventions for health are becoming increasingly available, and among the preferred options, including during the COVID-19 pandemic. This research assessed the extent of attention to laws and policies, human rights and gender in the implementation of self-care interventions for sexual and reproductive health (SRH), to identify where additional efforts to ensure an enabling environment for their use and uptake will be useful. A literature review of relevant studies published between 2010 and 2020 was conducted using PubMed, Scopus and Web of Science. Relevant data were systematically abstracted from 61 articles. In March–April 2021, semi-structured interviews were conducted with 10 key informants, selected for their experience implementing self-care interventions for SRH, and thematically analysed. Laws and policies, rights and gender are not being systematically addressed in the implementation of self-care interventions for SRH. Within countries, there is varied attention to the enabling environment including the acceptability of interventions, privacy, informed consent and gender concerns as they impact both access and use of specific self-care interventions, while other legal considerations appear to have been under-prioritised. Operational guidance is needed to develop and implement supportive laws and policies, as well as to ensure the incorporation of rights and gender concerns in implementing self-care interventions for SRH.

The cost effectiveness and optimal configuration of HIV self-test distribution in South Africa: a model analysis

BACKGROUND

HIV self-testing (HIVST) has been shown to be acceptable, feasible and effective in increasing HIV testing uptake. Novel testing strategies are critical to achieving the UNAIDS target of 95% HIV-positive diagnosis by 2025 in South Africa and globally.

METHODS

We modelled the impact of six HIVST kit distribution modalities (community fixed-point, taxi ranks, workplace, partners of primary healthcare (PHC) antiretroviral therapy (ART) patients), partners of pregnant women, primary PHC distribution) in South Africa over 20 years (2020-2039), using data collected alongside the Self-Testing AfRica Initiative. We modelled two annual distribution scenarios: (A) 1 million HIVST kits (current) or (B) up to 6.7 million kits. Incremental economic costs (2019 US$) were estimated from the provider perspective; assumptions on uptake and screening positivity were based on surveys of a subset of kit recipients and modelled using the Thembisa model. Cost-effectiveness of each distribution modality compared with the status-quo distribution configuration was estimated as cost per life year saved (estimated from life years lost due to AIDS) and optimised using a fractional factorial design.

RESULTS

The largest impact resulted from secondary HIVST distribution to partners of ART patients at PHC (life years saved (LYS): 119 000 (scenario A); 393 000 (scenario B)). However, it was one of the least cost-effective modalities (A: $1394/LYS; B: $4162/LYS). Workplace distribution was cost-saving ($52-$76 million) and predicted to have a moderate epidemic impact (A: 40 000 LYS; B: 156 000 LYS). An optimised scale-up to 6.7 million tests would result in an almost threefold increase in LYS compared with a scale-up of status-quo distribution (216 000 vs 75 000 LYS).

CONCLUSION

Optimisation-informed distribution has the potential to vastly improve the impact of HIVST. Using this approach, HIVST can play a key role in improving the long-term health impact of investment in HIVST.

The cost and intermediary cost-effectiveness of oral HIV self-test kit distribution across 11 distribution models in South Africa

BACKGROUND

Countries around the world seek innovative ways of closing their remaining gaps towards the target of 95% of people living with HIV (PLHIV) knowing their status by 2030. Offering kits allowing HIV self-testing (HIVST) in private might help close these gaps.

METHODS

We analysed the cost, use and linkage to onward care of 11 HIVST kit distribution models alongside the Self-Testing AfRica Initiative's distribution of 2.2 million HIVST kits in South Africa in 2018/2019. Outcomes were based on telephonic surveys of 4% of recipients; costs on a combination of micro-costing, time-and-motion and expenditure analysis. Costs were calculated from the provider perspective in 2019 US$, as incremental costs in integrated and full costs in standalone models.

RESULTS

HIV positivity among kit recipients was 4%-23%, with most models achieving 5%-6%. Linkage to confirmatory testing and antiretroviral therapy (ART) initiation for those screening positive was 19%-78% and 2%-72% across models. Average costs per HIVST kit distributed varied between $4.87 (sex worker model) and $18.07 (mobile integration model), with differences largely driven by kit volumes. HIVST kit costs (at $2.88 per kit) and personnel costs were the largest cost items throughout. Average costs per outcome increased along the care cascade, with the sex worker network model being the most cost-effective model across metrics used (cost per kit distributed/recipient screening positive/confirmed positive/initiating ART). Cost per person confirmed positive for HIVST was higher than standard HIV testing.

CONCLUSION

HIV self-test distribution models in South Africa varied widely along four characteristics: distribution volume, HIV positivity, linkage to care and cost. Volume was highest in models that targeted public spaces with high footfall (flexible community, fixed point and transport hub distribution), followed by workplace models. Transport hub, workplace and sex worker models distributed kits in the least costly way. Distribution via index cases at facility as well as sex worker network distribution identified the highest number of PLHIV at lowest cost.

Youth-friendly HIV self-testing: Acceptability of campus-based oral HIV self-testing among young adult students in Zimbabwe

BACKGROUND

Targeted HIV testing strategies are needed to reach remaining undiagnosed people living with HIV and achieve the UNAIDS' 95-95-95 goals for 2030. HIV self-testing (HIVST) can increase uptake of HIV testing among young people, but user perspectives on novel distribution methods are uncertain. We assess the acceptability, perceived challenges, and recommendations of young adult lay counselor-led campus-based HIVST delivery among tertiary school students aged 18-24 years in Zimbabwe.

METHODS

We purposively sampled participants from an intervention involving campus-based HIVST using lay workers for distribution. We conducted in-depth interviews (IDIs) and focus group discussions (FGDs) among young adults from 10 universities and colleges in Zimbabwe who: (1) self-tested on campus; (2) self-tested off campus; and (3) opted not to self-test. We audio recorded and transcribed all interviews. Using applied thematic analysis, two investigators identified emergent themes and independently coded transcripts, achieving high inter-coder agreement.

RESULTS

Of the 52 young adults (53.8% male, 46.1% female) interviewed through 26 IDIs and four FGDs, most IDI participants (19/26, 73%) favored campus-based HIVST, describing it as a more autonomous, convenient, and socially acceptable experience than other facility or community-based HIV testing services. Despite general acceptability, participants identified challenges with this delivery model, including: perceived social coercion, insufficient privacy and access to post-test counseling. These challenges influenced some participants to opt against self-testing (6/52, 11.5%). Recommendations for improved implementation included integrating secondary distribution of test kits and increased HIV counseling options into campus-based programs.

CONCLUSIONS

Barriers to HIV testing among young people are numerous and complex. As the number of new HIV infections among youth continue to grow worldwide, targeted strategies and youth friendly approaches that increase access to testing are needed to close the diagnostic coverage gap. This is the first study to describe young adult acceptance of campus-based delivery of HIVST by lay counselors in Zimbabwe.

Implementation outcomes of HIV self-testing in low- and middle- income countries: A scoping review

INTRODUCTION

HIV self-testing (HIV-ST) is an effective means of improving HIV testing rates. Low- and middle-income countries (LMIC) are taking steps to include HIV-ST into their national HIV/AIDS programs but very few reviews have focused on implementation in LMIC. We performed a scoping review to describe and synthesize existing literature on implementation outcomes of HIV-ST in LMIC.

METHODS

We conducted a systematic search of Medline, Embase, Global Health, Web of Science, and Scopus, supplemented by searches in HIVST.org and other grey literature databases (done 23 September 2020) and included articles if they reported at least one of the following eight implementation outcomes: acceptability, appropriateness, adoption, feasibility, fidelity, cost, penetration, or sustainability. Both quantitative and qualitative results were extracted and synthesized in a narrative manner.

RESULTS AND DISCUSSION

Most (75%) of the 206 included articles focused on implementation in Africa. HIV-ST was found to be acceptable and appropriate, perceived to be convenient and better at maintaining confidentiality than standard testing. The lack of counselling and linkage to care, however, was concerning to stakeholders. Peer and online distribution were found to be effective in improving adoption. The high occurrence of user errors was a common feasibility issue reported by studies, although, diagnostic accuracy remained high. HIV-ST was associated with higher program costs but can still be cost-effective if kit prices remain low and HIV detection improves. Implementation fidelity was not always reported and there were very few studies on, penetration, and sustainability.

CONCLUSIONS

Evidence supports the acceptability, appropriateness, and feasibility of HIV-ST in the LMIC context. Costs and user error rates are threats to successful implementation. Future research should address equity through measuring penetration and potential barriers to sustainability including distribution, cost, scale-up, and safety.

Acceptability of blood-based HIV self-testing among adolescents aged 15-19 years at risk of HIV acquisition in Bangkok

INTRODUCTION

Young men who have sex with men (YMSM) and young transgender women (YTGW) in Thailand are at high HIV risk. HIV self-tests (HIVSTs) are rapidly administrable and prompt linkage to HIV treatment or prevention services. This study assesses the acceptability and feasibility of blood-based HIVST use in adolescents.

METHODS

A cross-sectional study was conducted among YMSM and YTGW aged 15-19 years with HIV acquisition risk. Participants completed questionnaires on the HIVST and then administered INSTI® independently, an HIVST immunoassay detecting gp41 and gp36 antibodies from finger-stick blood. Confirmatory HIV antibody tests were performed.

RESULTS

Between July and September 2020, 90 adolescents were enrolled. Mean (SD) age was 17.6 (1.1) years. Half (N = 45) were YMSM. Forty-six (51%) were first-time HIV testers, and 32 (36%) had "ever used" HIV pre-exposure prophylaxis (PrEP). Two (2.2%, 95% CI: 0.0-5.3) tested positive, 21 (23.4%) invalid, and 67 (74.4%) negative. Invalidity causes included 17 (81%) insufficient blood, 3 (14%) buffer spillage, and 1 (5%) procedural missteps; all had negative HIV antibody tests. HIV self-test acceptability was 87.8% (95% CI: 81.0-94.5). Most (79%) preferred HIVST performance in hospital rather than at home.

CONCLUSIONS

HIVSTs are acceptable in HIV at-risk adolescents. Blood-based HIVSTs should be positioned as rapid point-of-care tests with real-time linkage to HIV services.

Preferred HIV Testing Modalities Among Adolescent Girls and Young Women in Kenya

PURPOSE

To improve testing coverage, it is imperative to determine adolescent girls and young women (AGYW) preferences about HIV testing modality and where they prefer receiving services.

METHODS

Participants were enrolled between May 2017 and April 2018 from three sites in Homa Bay County, Nyanza region, western Kenya. We explored two recruitment approaches (home-based vs. mobile-event based) and three HIV testing options (oral self-test, staff-administered, or referral to health facility). Exact logistic regression compared yield of newly diagnosed HIV and high-risk HIV-negatives from the recruitment and testing option strategies.

RESULTS

A total of 1,198 participants were enrolled, 1,046 (87.3%) at home and 152 (12.7%) at mobile events. Most participants (928, 77.5%) chose staff-aided testing either at home or at a mobile event; 268 (22.4%) chose self-testing; and only 2 (.2%) chose facility referral. Prevalence of newly diagnosed HIV-positives was 2.7% (32/1,198) and 36.8% (429/1,166) of HIV-negative AGYW were identified as high risk. We identified more newly diagnosed HIV infection among AGYW recruited at mobile events than at home (OR = 3.11; 95% CI: 1.33-6.74; p = .02). High-risk status was related to neither recruitment strategy nor testing modality. Older age was associated with increased odds of selecting an oral self-test (OR = 1.85; 95% CI: 1.06-3.22).

CONCLUSIONS

More than one-third of AGYW were at elevated risk of HIV infection, and those unaware of their HIV infection were more likely to be identified at a mobile outreach. Though self-testing was not the dominant preferred strategy, self-tests were performed accurately and with high confidence. These findings can help inform efficient identification of undiagnosed HIV infection and high risk for seroconversion among AGYW in similar settings.

Exploring perceptions of low risk behaviour and drivers to test for HIV among South African youth

Human Immunodeficiency Virus (HIV) prevalence among South African youth is high, yet HIV testing remains suboptimal. We explored how perceptions of HIV risk and behaviours informed decisions to test for HIV. This study was conducted from April 2018 to March 2019 in Ekurhuleni district, Gauteng Province with males and females aged between 15–24 years. Twenty-five youth with unknown HIV status participated in in-depth interviews (IDIs); while four focus group discussions (FGDs) were conducted with those that previously tested for HIV. Probes used in the guides included types of incentives that youth would value when testing for HIV or receiving treatment; barriers and motivators to HIV testing; enablers and challenges to using cellphone technology and preferences on type of social media that could be used to create awareness about HIV testing services. IDIs and FGDs were audio-recorded, transcribed, and translated. QSR NVIVO 10 was used for the analysis. The majority of the youth perceived that their risk of HIV infection was low due to factors such as being young, lacking physical signs of HIV, being sexually inactive and parents not being HIV positive. However, youth identified high risk behaviours such as unprotected sex, multiple sexual partners, excessive drinking of alcohol, being victims of sexual abuse, road accidents and violent behaviour as increasing their vulnerability to HIV. Most youth highlighted cues to action that would motivate them to test for HIV such as support of parents, receiving incentives, improved confidentiality during HIV testing and receiving information about HIV via social media (Facebook, Twitter and Whatsapp). Despite perceptions of low risk to HIV, youth remain vulnerable to HIV. Disseminating HIV information via digital platforms; giving youth options to choose between testing locations that they consider to be private; providing incentives and equipping parents/guardians to encourage youth to test could optimise HIV testing.

Acceptability and correlates of HIV self-testing among university students in northern Nigeria

Concerns about stigma and confidentiality limit the uptake of HIV testing and counseling (HTC) among young adults. HIV self-testing has been offered as a youth-friendly alternative to conventional HTC. We conducted a cross-sectional study to assess HTC uptake, willingness to self-test, and their predictors among university students (n = 399) in Kano, Nigeria. Anonymous self-administered questionnaires were provided to participants. Adjusted odd ratios were generated for predictors with logistic regression models. The results showed that only 35.8% (n = 143) of participants had previous HTC.Most respondents (70.4%, n = 281) were willing to self-test. HTC was associated with year of college (500 Level vs. 100 Level), adjusted odds ratio (AOR, [95% Confidence Interval (CI)] = 0.44 (0.19-0.97), campus residence (off- vs. on-campus, AOR = 0.45; 95%CI: 0.28-0.73), sexual activity in the past six months (AOR = 0.39; 95%CI: 0.24-0.64), willingness to self-test (AOR = 0.38; 95%CI: 0.22-0.66), and consistent condom use (AOR = 4.45; 95%CI: 1.41-14.08). Students who were older (≥ 30 vs. <20 years, AOR = 0.20; 95%CI: 0.05-0.90) and female (AOR = 0.56; 95%CI: 0.32-0.98) were less likely to be willing to self-test, whereas students who were more senior (500 Level vs. 100 Level, AOR = 5.24; 95%CI: 1.85-14.84), enrolled in clinical science programs (vs. agriculture, AOR = 4.92; 95%CI: 1.51-16.05) or belonging to "other" ethnic groups (vs. Hausa-Fulani, AOR = 2.40; 95%CI: 1.11-5.19) were more willing to self-test. Overall HTC uptake was low, but acceptability of self-testing was high. College seniority, age, ethnicity, and program of study were associated with willingness to self-test. Our findings support the feasibility of scaling up HIV self-testing among university students in Nigeria.

HIV self-testing: The key to unlock the first 90 in West and Central Africa

The West and Central African region (WCAR) still registers some of the highest rates of new HIV infections worldwide (16%) despite a low prevalence of HIV (1.9%). In this region, only 48% of people living with HIV are aware of their HIV status. To fill this gap, HIV Self testing (HIVST) could potentially be an additional approach to overcome the barriers to diagnose HIV infected patients, therefore being one of the keys to unlock the first 90 as recommended by the World Health Organization (WHO) since 2016. However, many challenges remain for the adoption of HIVST in routine clinical practice in low prevalence settings and need to be contextualized to WCAR settings. We report in this paper some of the challenges and discuss opportunities for a successful implementation of HIVST in the WCAR.
