On Campus HIV Self-Testing Distribution at Tertiary Level Colleges in Zimbabwe Increases Access to HIV Testing for Youth

PurposeHIV self-testing allows youth to access testing outside of healthcare facilities. We investigated the feasibility of peer distribution of HIV self-testing (HIVST) kits to youth aged 16–24 years and examined the factors associated with testing off-site rather than at distribution points. MethodsFrom July 2019 to March 2020, HIVST kits were distributed on 12 tertiary education campuses throughout Zimbabwe. Participants chose to test at the HIVST distribution point or off-site. Factors associated with choosing to test off-site and factors associated with reporting a self-test result for those who tested off-site were investigated using logistic regression. ResultsIn total, 5,351 participants received an HIVST kit, over 129 days, of whom 3,319 (62%) tested off-site. The median age of recipients was 21 years (interquartile range 20–23); 64% were female. Overall, 2,933 (55%) returned results, 23 (1%) of which were reactive. Being female (adjusted odds ratio [aOR] 1.16, 95% confidence interval [CI] 1.03–1.31), living on campus (aOR 1.24, 95% CI 1.09–1.40), used a condom at last sex (aOR 1.44, 95% CI 1.26–1.65), and previous knowledge of HIVST (aOR 1.22, 95% CI 1.09–1.37) were associated with off-site testing. Attending a vocational college and teachers training college compared to a university was associated with choosing to return results for those who tested off-site (OR 2.40, 95% CI 1.65–3.48, p < .001). DiscussionHIVST distribution is an effective method of reaching a large number of youth over a short period of time. Efforts to increase awareness and roll out of HIVST on campuses should be coupled with support for linkage to HIV prevention and treatment services.

Reaching Adolescent Girls and Young Women With HIV Self-Testing and Contraception at Girl-Friendly Drug Shops: A Randomized Trial in Tanzania

PurposeWe hypothesized that an intervention designed to create girl-friendly drug shops would increase access to sexual and reproductive health products and services among adolescent girls and young women (AGYW) (ages 15–24 years) in Tanzania. MethodsWe conducted a four-month randomized trial at 20 drug shops in Shinyanga, Tanzania from August–December 2019 to determine if the Malkia Klabu (“Queen Club”) intervention increased AGYW patronage and the provision of HIV self-testing (HIVST), contraception, and health facility referrals to AGYW (primary outcomes). Drug shops were randomized 1:1 to the intervention or comparison arm. All shops were provided with OraQuick HIVST kits to give to AGYW for free. Intervention shops implemented Malkia Klabu, a loyalty program for AGYW created using human-centered design through which AGYW could also access free contraception. We compared outcomes in intention-to-treat analyses using shop observations and shopkeeper records. ResultsBy endline, shops implementing Malkia Klabu had higher AGYW patronage than comparison shops (rate ratio: 4.4; 95% confidence interval: 2.0, 9.8). Intervention shops distributed more HIVST kits (median per shop: 130.5 vs. 58.5, P = .02) and contraceptives (325.5 vs. 7.0, P < .01) to AGYW and provided more referrals for HIV, family planning, or pregnancy services combined (3.5 vs. 0.5, P = .02) than comparison shops. DiscussionThe Malkia Klabu intervention increased AGYW patronage and the provision of HIVST kits, contraception, and referrals to AGYW at drug shops, despite HIVST kits being freely available at all participating shops. Enhancing drug shops with girl-friendly services may be an effective strategy to reach AGYW with sexual and reproductive health services.

Assessing young Kenyan women's willingness to engage in a peer-delivered HIV self-testing and referral model for PrEP initiation: A qualitative formative research study.

BackgroundPre-exposure prophylaxis (PrEP) is highly effective for HIV prevention, but uptake remains low, especially among adolescent girls and young women (AGYW) in Kenya. A model in which trained AGYW using PrEP deliver HIV self-tests to their close friends and refer them to PrEP may help increase PrEP uptake in this population. To understand AGYW's potential willingness to engage in such a model, we conducted a qualitative formative study in Kenya.MethodWe conducted semi-structured in-depth interviews (IDIs) with AGYW (16 to 24 years) in Kiambu County who were determined at risk of HIV acquisition. We purposively recruited “PrEP-naïve” (no prior PrEP use) and “PrEP-experienced” AGYW who used PrEP for at least 1 month within the previous year. We solicited perspectives on initiating/engaging in conversations about HIV risk and PrEP, distributing/receiving HIV self-test kits, and referring/following through on a referral to clinic-based HIV services. We analyzed verbatim transcripts using rapid qualitative analysis and a combination of inductive and deductive approaches, with the latter informed by the Integrated Behavior Model (IBM).ResultsFrom August to December 2020, we conducted 30 IDIs: 15 with PrEP-experienced and 15 with PrEP-naïve AGYW. Participants' median age was 20 [interquartile range (IQR): 20–22]. Overall, most participants anticipated that they would be willing to engage in this model. PrEP-experienced AGYW emphasized the salience of their concerns about friends' HIV risk behaviors, with several noting that they are already in the habit of discussing PrEP with friends. Many additionally expressed positive attitudes toward the proposed target behaviors, perceived these to be normative among AGYW, and expressed confidence in their ability to carry out the behaviors with proper support. Although few participants had HIVST experience, nearly all anticipated they would be able to use an HIV self-test kit correctly if provided instruction.ConclusionThe Kenyan AGYW who participated in this study generally anticipated that they would be willing to engage in a formal peer PrEP referral model enhanced with peer-delivered HIV self-tests. Future research is needed to pilot test this model to determine its acceptability, feasibility, and effect on HIVST and PrEP uptake within this population.

Spatiotemporal Distribution of HIV Self-testing Kits Purchased on the Web and Implications for HIV Prevention in China: Population-Based Study.

BackgroundHIV self-testing (HIVST) holds great promise for expanding HIV testing. Nonetheless, large-scale data on HIVST behavior are scant. Millions of HIVST kits are sold through e-commerce platforms each year.ObjectiveThis study aims to analyze the spatiotemporal distribution of the HIVST kit–purchasing population (HIVSTKPP) in China.MethodsDeidentified transaction data were retrieved from a leading e-commerce platform in China. A joinpoint regression model was used to examine annual trends of the HIVSTKPP rates by calculating average annual percentage change. Bayesian spatiotemporal analysis was performed to locate hot spots with HIVSTKPP rates. Spatial autocorrelation analysis and space-time cluster analysis were conducted to identify clusters of HIVSTKPP. High-high clusters of HIVSTKPP can be identified by spatial autocorrelation analysis, and high-high clusters indicate that a region and its surrounding region jointly had a higher-than-average HIVSTKPP rate. Spatial regression analysis was used to elucidate the association between the number of HIV testing facilities, urbanization ratio (the proportion of urban population in the total population), and gross domestic product per capita and the HIVSTKPP.ResultsBetween January 1, 2016, and December 31, 2019, a total of 2.18 million anonymous persons in China placed 4.15 million orders and purchased 4.51 million HIVST kits on the web. In each of these 4 years, the observed monthly size of the HIVSTKPP peaked in December, the month of World AIDS Day. HIVSTKPP rates per 100,000 population significantly increased from 20.62 in 2016 to 64.82 in 2019 (average annual percentage change=48.2%; P<.001). Hot spots were mainly located in municipalities, provincial capitals, and large cities, whereas high-high clusters and high-demand clusters were predominantly detected in cities along the southeast coast. We found positive correlations between a region’s number of HIV testing facilities, urbanization ratio, and gross domestic product per capita and the HIVSTKPP.ConclusionsOur study identified key areas with larger demand for HIVST kits for public health policy makers to reallocate resources and optimize the HIV care continuum. Further research combining spatiotemporal patterns of HIVST with HIV surveillance data is urgently needed to identify potential gaps in current HIV-monitoring practices.

Incentives to promote accessing HIV care and viral suppression among HIV self-screening test users who obtain a reactive result.

IntroductionAchieving viral suppression in people with HIV is crucial in ending the AIDS epidemic. Among users of HIV self-screening tests, low rates of linkage to care and early retention in care are key obstacles to achieving viral suppression. This study sought to evaluate the efficacy of financial incentives in supporting HIV case management.MethodsYoung adults within the inner city of Johannesburg, South Africa and surrounding areas who used HIV self-tests, were able to use WhatsApp to communicate with study personnel, reported a reactive or invalid result, and were confirmed to by HIV-positive were enrolled in the study. Participants were randomised to an intervention arm that received reminders and financial rewards for engaging in care, or to a control arm that received the standard of care. The primary outcome was HIV viral load at six months.ResultsAmong 2,388 HIV self-test kits that were distributed, 1757/2,388 (73,58%) recipients were able to use their phones to send photos to study personnel. 142/1,757 (8,08%) of these recipients reported reactive or invalid results. Upon confirmatory testing, 99/142 (69,71%) participants were identified as being HIV-positive and were enrolled in the study. 2 (1,41%) participants received an HIV negative result, and 41(28,87%) participants were either lost to follow-up or did not complete the confirmatory testing step. 20/99 (20,2%) from the intervention arm and 18/99 (18,18%) from the control arm completed the study (i.e., attended a 6 month follow up and participated in the exit interview). 29/99 (29,29%) were virally suppressed by at 6 months. Of those achieving viral suppression 15 (51,72%) were from the intervention arm.ConclusionFinancial incentives and reminders were not effective in promoting engagement with HIV care and viral suppression in this setting.

Facility-based HIV self-testing strategies may substantially and cost-effectively increase the number of men and youth tested for HIV in Malawi: results from an individual-based mathematical model.

IntroductionMalawi is rapidly closing the gap in achieving the UNAIDS 95‐95‐95 targets, with 90% of people living with HIV in Malawi aware of their status. As we approach epidemic control, interventions to improve coverage will become more costly. There is, therefore, an urgent need to identify innovative and low‐cost strategies to maintain and increase testing coverage without diverting resources from other HIV services. The objective of this study is to model different combinations of facility‐based HIV testing modalities and determine the most cost‐effective strategy to increase the proportion of men and youth testing for HIV.MethodsA data‐driven individual‐based model was parameterized with data from a community‐representative survey (socio‐demographic, health service utilization and HIV testing history) of men and youth in Malawi (data collected August 2019). In total, 79 different strategies for the implementation of HIV self‐testing (HIVST) and provider‐initiated‐testing‐and‐counselling at the outpatient department (OPD) were evaluated. Outcomes included percent of men/youth tested for HIV in a 12‐month period, cost‐effectiveness and human resource requirements. The testing yield was assumed to be constant across the scenarios.ResultsFacility‐based HIVST offered year‐round resulted in the greatest increase in the proportion of men and youth tested in the OPD (from 45% to 72%–83%), was considered cost‐saving for HIVST kit priced at $1.00, and generally reduced required personnel as compared to the status quo. At higher HIVST kit prices, and more relaxed eligibility criteria, all scenarios that considered year‐round HIVST in the OPD remained on the cost‐effectiveness frontier.ConclusionsFacility‐based HIVST is a cost‐effective strategy to increase the proportion of men/youth tested for HIV in Malawi and decreases the human resource requirements for HIV testing in the OPD—providing additional healthcare worker time for other priority healthcare activities.

A Retrospective Analysis to Review Access of HIV Self-testing During SARS-COV-2 Lockdown in Eswatini Community Settings, Eswatini: Quantitative Methods Study

The HIV self-testing (HIVST) program was introduced to reach people living with HIV who are still undiagnosed and also to ensure that HIV-negative individuals get access to effective HIV prevention services. HIV self-testing offers a discreet and convenient way to test, with the potential to reach individuals in need of HIV testing services but who may not otherwise test. The purpose of this study was to uncover access to HIVST during the first SARS-COV-2 lockdown period in 2020. This was a cross-sectional design approach that applied the RE-AIM framework principle. The study used historical data from the four regions in Eswatini (Shiselweni, Manzini, Lubombo, and Hhohho). These regions were selected based on ensuring adequate coverage and representativeness. Data were analysed using bivariate logistic regression analysis in Stata15 to assess the association between categorical variables, and the level of significance was set at a P-value less than 0.05. The results showed a total of 6158 clients were reached with HIVST kits. A total of 3031 (50%) were females, and 3127(51%) were males, and more outcomes were based on risk profiles and age. It is concluded that HIVST is one key strategy in reaching males who ordinarily lag when it comes to HIV testing services in Eswatini. These results show that access to HIV self-testing during the lockdown period in Eswatini illustrated positive advances as it reached the most at-risk population groups and has a potential for extended sustained use to benefit specific high-HIV-risk population groups.

Spatiotemporal Analysis of Online Purchase of HIV Self-testing Kits in China, 2015-2017: Longitudinal Observational Study.

BackgroundSince the introduction of HIV self-testing by UNAIDS in 2014, the practice has been extensively implemented around the world. HIV self-testing (HIVST) was developed in China around 2015, and the online purchase of HIVST kits through e-commerce platforms has since become the most important delivery method for self-testing, with advantages such as user-friendliness, speed, and better privacy protection.ObjectiveUnderstanding the spatiotemporal characteristics of online HIVST kit purchasing behavior and identifying potential impacting factors will help promote the HIV self-testing strategy.MethodsThe online retail data of HIVST kits from the 2 largest e-commerce platforms in China from 2015 to 2017 were collected for this study. The Bayesian spatiotemporal hierarchical model was used to investigate the spatiotemporal characteristics of online purchased HIVST kits. Ordinary least squares regression was used to identify potential factors associated with online purchase, including GDP per capita, population density, road density, HIV screening laboratory density, and newly diagnosed HIV/AIDS cases per 100,000 persons. The q statistics calculated by Geodetector were used to determine the interactive effect of every 2 factors on the online purchase.ResultsThe online purchase of HIVST kits increased rapidly in China from 2015 to 2017, with annual peak sales in May and December. Five economically superior regions in China, Pearl River Delta, Yangtze River Delta, Chengdu and surrounding areas, Beijing and Tianjin areas, and Shandong Peninsula, showed a comparatively higher spatial preference for online purchased HIVST kits. The GDP per capita (P<.001) and the rate of newly diagnosed HIV/AIDS cases per 100,000 persons (P<.001) were identified as 2 factors positively associated with online purchase. Among the factors we investigated in this study, 2 factors associated with online purchase, GDP per capita and the rate of newly diagnosed HIV/AIDS cases per 100,000 persons, also displayed the strongest interactive effect, with a q value of 0.66.ConclusionsIndividuals in better-off areas are more inclined to purchase HIVST kits online. In addition to economic status, the severity of the HIV epidemic is also a factor influencing the online purchase of HIVST kits.

Relative Effectiveness of Social Media, Dating Apps, and Information Search Sites in Promoting HIV Self-testing: Observational Cohort Study.

BackgroundSocial media sites, dating apps, and information search sites have been used to reach individuals at high risk for HIV infection. However, it is not clear which platform is the most efficient in promoting home HIV self-testing, given that the users of various platforms may have different characteristics that impact their readiness for HIV testing.ObjectiveThis study aimed to compare the relative effectiveness of social media sites, dating apps, and information search sites in promoting HIV self-testing among minority men who have sex with men (MSM) at an increased risk of HIV infection. Test kit order rates were used as a proxy to evaluate promotion effectiveness. In addition, we assessed differences in characteristics between participants who ordered and did not order an HIV test kit.MethodsCulturally appropriate advertisements were placed on popular sites of three different platforms: social media sites (Facebook, Instagram), dating apps (Grindr, Jack’D), and information search sites (Google, Bing). Advertisements targeted young (18-30 years old) and minority (Black or Latinx) MSM at risk of HIV exposure. Recruitment occurred in 2 waves, with each wave running advertisements on 1 platform of each type over the same period. Participants completed a baseline survey assessing sexual or injection use behavior, substance use including alcohol, psychological readiness to test, attitudes toward HIV testing and treatment, and HIV-related stigma. Participants received an electronic code to order a free home-based HIV self-test kit. Follow-up assessments were conducted to assess HIV self-test kit use and uptake of pre-exposure prophylaxis (PrEP) at 14 and 60 days post enrollment.ResultsIn total, 271 participants were enrolled, and 254 were included in the final analysis. Among these 254 participants, 177 (69.7%) ordered a home HIV self-test kit. Most of the self-test kits were ordered by participants enrolled from dating apps. Due to waves with low enrollment, between wave statistical comparisons were not feasible. Within wave comparison revealed that Jack’D showed higher order rates (3.29 kits/day) compared to Instagram (0.34 kits/day) and Bing (0 kits/day). There were no associations among self-test kit ordering and HIV-related stigma, perceptions about HIV testing and treatment, and mistrust of medical organizations.ConclusionsOur findings show that using popular dating apps might be an efficient way to promote HIV self-testing. Stigma, perceptions about HIV testing and treatment, or mistrust of medical organizations may not affect order rates of HIV test kits promoted on the internet.Trial RegistrationClinicalTrials.gov NCT04155502; https://clinicaltrials.gov/ct2/show/NCT04155502International Registered Report Identifier (IRRID)RR2-10.2196/20417

Willingness to Pay for HIV Prevention Commodities Among Key Population Groups in Nigeria.

Key population (KP) groups, such as female sex workers and men who have sex with men, in Nigeria rely on free HIV prevention commodities, including pre-exposure prophylaxis (PrEP) and HIV self-testing (HIVST) kits, provided through foreign aid. We investigated the willingness of KP groups to use and pay for HIV prevention commodities to support improved sustainable HIV prevention programming. In 2020, we conducted a cross-sectional survey in 3 states with KP groups. The survey covered sociodemographic characteristics and willingness to use and pay for PrEP, HIVST, and condoms, and we used a bidding game iteration process to collect data on factors that influence willingness to use and pay for the commodities. We performed bivariate and multivariable regression analyses to explore factors that may determine willingness to pay and the maximum amount willing to pay. Of the participants surveyed, 73% were willing to pay for PrEP services, 81% were willing to pay for HIVST, and 87% were willing to pay for condoms. Willingness to pay varied between the commodities and was associated with, among other variables: age, KP group, marital status, level of education, employment status, place of residence, average monthly income, and familiarity with the commodity in question. We demonstrate that KP groups are willing to pay for HIV prevention commodities, but there is a need to bridge the gap between the maximum amount they are willing to pay and retail prices. If prices are reduced, the willingness to pay may result in high consumption and positive returns for the private sector.

HIV Prevention Tools Across the Pregnancy Continuum: What Works, What Does Not, and What Can We Do Differently?

Multiple tools exist to support the primary prevention of HIV in pregnant and postpartum women; however, there are opportunities to enhance their use and impact. This review summarizes the current status of HIV prevention tools and existing gaps and opportunities to improve their use along the pregnancy care continuum. HIV screening efforts have steadily improved with close to universal screening of pregnant women in several East and Southern African countries. Strategies to implement partner testing through the distribution of HIV self-test kits are promising though linkage to care remains challenging. Syphilis screening rates are increasing though detection of other sexually transmitted infections could benefit from improved diagnostic capacity. Male and female condoms are rarely used and are often not the optimal tool of choice during pregnancy. Oral pre-exposure prophylaxis (PrEP) is a promising tool, although barriers such as the need for daily adherence, side effects, and stigma may limit its use. There is a growing pipeline of PrEP agents with alternative delivery platforms that might suit women's preferences better and supports the notion that choice is vital to improving HIV prevention coverage during the pregnancy-postpartum continuum. Clear guidance on which tools to use and how to use them, safety data supporting their use, and surveillance data documenting the scale and effectiveness of the tools will be imperative in establishing a path to more impactful prevention efforts among pregnant and postpartum women.

Comparing the Effects of Oral HIV Self-Testing With Those of Standard HIV Testing for Men Who Have Sex With Men (MSM): A Systematic Review and Meta-Analysis.

The WHO recommends HIV self-testing (HIVST) as an innovative strategy and an additional testing approach to attain UNAIDS targets to end HIV by 2030. HIVST is a process whereby a person collects his or her own specimen (either oral fluid or blood), performs an HIV test, and interprets the result. It has been described as a discreet and convenient way to reach the hidden, unreached key populations (KPs) who do not know their HIV status or do not get tested. Among the KPs, men who have sex with men (MSM) is one such group that by far remains hidden due to feared stigma and discrimination associated both with their sexuality and HIV. Fear of pain and blood while HIV testing also deters MSM from getting tested. In this review, we assessed the effect of oral HIVST on the uptake and frequency of testing and risk behavior as compared to standard HIV testing.For this review, we systematically searched various electronic databases for clinical trials comparing HIVST to standard HIV testing from January 1, 2011, to December 31, 2021. A meta-analysis of studies was conducted using a random-effects model for relative risks (RRs) and 95% confidence intervals (CIs). The protocol was registered with PROSPERO, and PRISMA guidelines for systematic reviews and meta-analyses were followed. The quality of the clinical trials was assessed using Cochrane’s risk of bias tool version 2.0 (RoB 2.0).We identified eight studies comparing HIVST to standard HIV testing services (HTSs). The eight randomized controlled trials (RCTs) enrolled 5,297 participants, of which 5,212 were MSM and 85 were transgender (TG) women. Seven RCTs were conducted in high-income countries (HICs): four in the USA, two in Australia, and one in Hong Kong. One was conducted in a low-middle-income country (LMIC) in Myanmar.In all the studies, HIVST intervention was provided with oral HIVST kits, except for one study in which both blood-based and oral HIVST kits were used. Meta-analysis (five RCTs) showed that HIVST increased the uptake of HIV testing by 1.43 times compared to standard of care (SoC) (RR = 1.43; 95% CI = 1.25, 1.64). Meta-analysis (four RCTs) found that HIVST increased the mean number of HIV tests by 2.34 during follow-up (mean difference = 2.34; 95% CI = 1.66, 3.02). Meta-analysis (four RCTs) showed that HIVST doubled the detection of new HIV infections among those tested (RR = 2.10; 95% CI = 1.35, 3.28) and reported higher repeat testing as compared to the control arm (RR = 2.04; 95% CI = 1.22, 3.42). A meta-analysis of three trials found no significant difference in risk behavior in respect of condomless anal intercourse (CAI) (odds ratio (OR) = 0.90; 95% CI = 0.67, 1.22) and multiple male partnership (RR = 0.89; 95% CI = 0.83, 0.94).Oral HIVST could increase the HIV testing and detection of new HIV infections among MSM who may not otherwise test, as compared to standard testing services alone. However, further research from low-middle-income countries is required for generalizability.

Targeted Implementation of HIV Self-Testing Increases Testing Uptake Among Partners of Index Persons Known to Have HIV in Kenya.

Partners of persons living with HIV (PLHIV) are at a high risk of HIV acquisition, particularly if PLHIV are newly diagnosed or not virally suppressed. A focused partner HIV testing strategy could stimulate efficient identification of persons for pre-exposure prophylaxis (PrEP) or antiretroviral therapy (ART) programs. We sequentially implemented 2 partner testing strategies at 2 Kenyan HIV clinics: (1) an invitation for clinic-based testing and (2) HIV self-testing (HIVST) kits distribution to index PLHIV. For each testing strategy, we enrolled approximately 150 consecutive index PLHIV with partners of unknown HIV status, not on ART, <6 months on ART, or who had detectable viral load. We compared partner engagement, testing uptake, and linkage for ART or PrEP between the 2 testing strategies. Of 313 index PLHIV enrolled (160 in invitation, 153 in HIVST), the median age was 32 years (interquartile range 26-40) and 76% were women. Overall, 73% of participants (229) discussed HIV testing with their partners: 76% (121) in the invitation strategy vs 71% (108) in the HIVST strategy [adjusted odds ratio (adjOR): 0.54, 95% confidence interval (CI): 0.31 to 0.97]. Overall, 52% (79) partners in the HIVST strategy tested vs 38% (60) in the invitation strategy (adjOR: 1.78, 95% CI: 1.13 to 2.78). Among partners engaged, 73% in the HIVST strategy vs 50% in the invitation tested (adjOR: 2.68, 95% CI: 1.46 to 4.96); 25% (35/139) tested positive for HIV. Eighty-nine percentage (31/35) who tested positive initiated treatment, but only 21% (20/93) who tested negative initiated PrEP. HIVST kit distribution to PLHIV with partners of unknown HIV status effectively increased partner testing. Only one-fifth of partners who tested negative initiated PrEP-thus innovations to link to prevention services are urgently needed.

Routine programmatic data show a positive population-level impact of HIV self-testing: the case of Côte d'Ivoire and implications for implementation.

Objectives:We estimate the effects of ATLAS's HIV self-testing (HIVST) kit distribution on conventional HIV testing, diagnoses, and antiretroviral treatment (ART) initiations in Côte d’Ivoire.Design:Ecological study using routinely collected HIV testing services program data.Methods:We used the ATLAS's programmatic data recorded between the third quarter of 2019 and the first quarter of 2021, in addition to data from the President's Emergency Plan for AIDS Relief dashboard. We performed ecological time series regression using linear mixed models. Results are presented per 1000 HIVST kits distributed through ATLAS.Results:We found a negative but nonsignificant effect of the number of ATLAS’ distributed HIVST kits on conventional testing uptake (−190 conventional tests; 95% confidence interval [CI]: −427 to 37). The relationship between the number of HIVST kits and HIV diagnoses was significant and positive (+8 diagnosis; 95% CI: 0 to 15). No effect was observed on ART initiation (−2 ART initiations; 95% CI: −8 to 5).Conclusions:ATLAS’ HIVST kit distribution had a positive impact on HIV diagnoses. Despite the negative signal on conventional testing, even if only 20% of distributed kits are used, HIVST would increase access to testing. The methodology used in this paper offers a promising way to leverage routinely collected programmatic data to estimate the effects of HIVST kit distribution in real-world programs.

The Impact of COVID-19 Restrictions on Online Sales of HIV Self-Test Kits and Implications for HIV Prevention: Analysis of Transaction Data from a Leading E-commerce Platform in China.

The effect of the COVID-19 epidemic on HIV self-testing (HIVST) remains unclear. We aimed to quantify the impact of COVID restrictions on HIVST kit purchasing behaviors in mainland China. Deidentified transaction data were retrieved from a large online shopping platform. An interrupted time series model was constructed to examine the impact of COVID restrictions on the weekly number of anonymous customers purchasing HIVST kits, online orders, and purchased kits. A total of 2.32 million individuals submitted 4.46 million orders for 4.84 million HIVST kits between January 7, 2016, and April 22, 2020. Compared with expected levels, assuming COVID-19 epidemic and related restrictions had not happened, the number of purchasers, orders, and kits decreased by an estimated 10,500 (51.7%), 18,000 (55.3%), and 18,500 (54.9%) in the first week (January 23, 2020, to January 29, 2020) after COVID restrictions were implemented, respectively. As restrictions eased, the number of purchasers, orders, and kits increased by an average of 7.4%, 4.8%, and 4.9% per week, respectively. In the first week after COVID restrictions were lifted (April 9, 2020, to April 15, 2020), the number of purchasers returned to expected levels, whereas the number of orders and kits were still lower than expected levels. The impact of COVID restrictions on outcomes at the beginning of COVID restrictions and the increasing trends of outcomes were larger among those living in regions with higher COVID-19 incidence (eg, Wuhan city and Hubei province). Online sales of HIVST kits were significantly impacted by COVID restrictions, and HIVST kit purchasing patterns returned to expected levels after restrictions were lifted.

The acceptability and usability of two HIV self-test kits among men who have sex with men: a randomised crossover trial.

ObjectivesTo compare the usability and acceptability of oral fluid‐ and blood‐based HIV self‐test kits among men who have sex with men in Australia.DesignRandomised crossover trial.Setting, participantsGay, bisexual, and other men aged 18 years or older who have sex with men, who attended two metropolitan sexual health clinics in Sydney and Melbourne, 7 January – 10 December 2019.Main outcome measuresEase of use of HIV self‐test kits; preferred HIV self‐test type; difficulties encountered during HIV self‐testing.Results170 men were recruited (median age, 34 years; interquartile range, 29–43 years); 144 identified as gay (85%), 96 were born outside Australia (57%). Participants were more likely to report the oral fluid HIV self‐test was easy to use than the blood‐based self‐test (oral fluid, 99%; blood, 86%; odds ratio [OR], 3.0; 95% confidence interval [CI], 1.4–6.6). The oral fluid test was preferred by 98 participants (58%; 95% CI, 50–65%), the blood‐based test by 69 (41%; 95% CI, 33–48%). Difficulties with the oral fluid test kit identified by observing nurses included problems placing the buffer solution into the stand (40 of 170 participants, 24%) and not swabbing both gums (23 of 169, 14%); difficulties with the blood‐based test kit included problems filling the device test channel (69 of 170, 41%) and squeezing the finger firmly enough to generate a blood drop (42 of 170, 25%). No participant received an invalid result with the oral fluid self‐test; two of 162 participants (1%) received invalid results with the blood self‐test. After adjusting for age, education level, and ethnic background, characteristics associated with higher odds of using HIV self‐testing in the future were overseas birth (adjusted OR, 3.07; 95% CI, 1.42–6.64), and self‐evaluated ease of use and confidence in using the kits.ConclusionIt is important to provide options for obtaining both oral fluid‐ and blood‐based HIV self‐tests. The usability and acceptability of both kits were high, but the ease of use and perceived accuracy influenced test kit preference.

Feasibility and Acceptability of HIV Self-Test Kit Distribution Through PrEP Clients' Social and Sexual Networks to Increase HIV Testing and PrEP Information.

To determine the feasibility, acceptability, and implementation of a HIV self-test (HIVST) program through PrEP clients' social and sexual networks. HIV testing is critical for treatment and prevention engagement. HIVST kits can overcome barriers to testing. A negative result is an opportunity to provide PrEP information. We describe implementation factors associated with engaging current Mobile PrEP (MP) clients to distribute HIVST kits and PrEP information through their networks. Community venues in Miami-Dade County, Florida. A baseline survey collected network information and explored distribution plans for offering HIVST kits. A follow-up survey evaluated use and distribution. A logic model describes the process of implementation and evaluation. Up to 4 Ora-Quick HIV ST kits were offered to 81 MP clients. A brief training included resources for posttest engagement. Forty-four percent of the kits were reported as distributed. Of 81 MP clients offered kits, 50 (62%) accepted. In a follow-up survey, 77% of MP clients distributed at least 1 kit. Fifty-six (86%) social network members were Latino, and 9 (14%) were Black. Three of 4 MP clients engaged in PrEP discussions (77%) with SN members. Reported reasons for HIVST kit use included convenience, confidentiality, privacy concerns, and discomfort with going to a testing site. MP clients reported that kit distribution was affected by the COVID-19 pandemic. HIV ST kits allowed PrEP users to engage others in their social and sexual networks for HIV testing and information regarding PrEP. Work to scale-up this intervention is underway.

Economic Analysis of Low Volume Interventions Using Real-World Data: Costs of HIV Self-Testing Distribution and HIV Testing Services in West Africa From the ATLAS Project.

Achieving the first 95 of the UNAIDS targets requires the implementation of innovative approaches to knowing one's HIV status. Among these innovations is the provision of HIV self-testing (HIVST) kits in west Africa by the international partner organization Solthis (IPO). In order to provide guidance for the optimal use of financial resources, this study aims to estimate the program and site level costs of dispensing HIVST as well as HIV testing services (HTS)-excluding HIVST-in health facilities in Côte d'Ivoire, Mali and Senegal as part of the ATLAS project. We estimated from the provider's perspective, HIVST and HTS incremental costs using top-down and bottom-up costing approaches and conducted a time and motion study. We identified costs at the program level for HIVST (including IPO central costs) and at the site level for HIVST and HTS. The economic costs of distributing HIVST kits were assessed in 37 health facilities between July 2019 and March 2021 (21 months). Sensitivity analyses were also performed on unit costs to examine the robustness of our estimates related to key assumptions. In total, 16,001 HIVST kits were dispensed for 32,194 HTS sessions carried out. Program level HIVST average costs ranged $12-286, whereas site level costs ranged $4-26 across distribution channels and countries. Site level HTS costs ranged $7-8 per testing session, and ranged $72-705 per HIV diagnosis. Across countries and channels, HIVST costs were driven by personnel (27-68%) and HIVST kits (32-73%) costs. The drivers of HTS costs were personnel costs ranging between 65 and 71% of total costs across distribution channels and countries, followed by supplies costs between 21 and 30%. While program level HIVST average costs were high, site level HIVST average costs remained comparable to HTS costs in all countries. Health facility-based distribution channels operating at low volume exhibit high proportion of central costs which should be considered carefully for financial planning when run alongside high volumes mobile outreach distribution channels. HIVST can diversify the HIV testing offer at health facilities, thus improving access to screening for target populations not reached by HTS services.

Testing a social network approach to promote HIV self-testing and linkage to care among fishermen at Lake Victoria: study protocol for the Owete cluster randomized controlled trial

BackgroundNearly 50% of men living with HIV in many countries are unaware of their HIV status; men also have lower uptake of HIV treatment and pre-exposure prophylaxis (PrEP). In SSA, highly mobile men such as those working in fishing communities alongside Lake Victoria have low uptake of HIV testing and low rates of linkage to HIV treatment and PrEP, despite increasing availability of these services. HIV self-testing (HIVST) kits hold promise for overcoming barriers to HIV testing and linkage to services for HIV-positive and HIV-negative men. We describe here a protocol for an HIV status-neutral, social network-based approach to promote HIV testing, linkage to care and prevention, and better health outcomes, including adherence, in fishermen around Lake Victoria.MethodsUtilizing beach management unit (BMU) registries of fishermen operating in three Lake Victoria fishing communities in Siaya County, Kenya, we completed a census and social network mapping to identify close social networks of men. Network clusters identified by a socially-central lead (“promotor”) and selected to ensure maximal separation between treatment and control will be randomized. Promotors in both arms will receive basic HIV training; intervention promotors are further trained in HIVST to distribute kits to their cluster, while control promotors will distribute to their cluster vouchers for free HIVST at nearby clinics. We will test whether these promoters can enhance linkage to ART and PrEP after self-testing, thereby addressing a key limitation of HIVST. We will also measure 6- and 12-month viral load in those living with HIV and PrEP adherence among those without HIV via urine tenofovir levels as objective markers of adherence.DiscussionThis study has the potential to improve HIV health and promote HIV prevention among a hard to reach, at-risk, and highly mobile population of men in Western Kenya—a critical population in Kenya’s HIV prevention and treatment program. Further, if successful, this innovative social networks-based model could be scaled at the regional level to address HIV prevention and care among similarly at-risk populations of men in eastern Africa and inland fisheries settings across the continent.Trial registrationSelf-Test Strategies and Linkage Incentives to Improve ART and PrEP Uptake in Men, registered on February 26, 2021, registration #NCT04772469.
