Experiences using and organizing HIV self-testing

Assessing the impact of HIV self-testing on diagnosis rates in vulnerable groups in belo horizonte, Brazil: A cross-sectional analysis

Background

In recent years, HIV self-testing (HIVST) has emerged as a promising approach to enhance accessibility and uptake of HIV testing, particularly among populations at high risk for sexually transmitted infections (STIs). Despite its potential benefits, the effectiveness, and challenges of HIVST warrant careful examination to inform public health strategies effectively. This study investigates the effectiveness and challenges of HIV self-testing (HIVST) in populations at high risk for sexually transmitted infections (STIs). Study design: Cross-sectional study.

Methods

We employed questionnaires, HIVST, and standard tests for HIV, Hepatitis C, and Syphilis, in patients exhibiting STI risk behaviors in Belo Horizonte, Brazil, between August and November of 2019.

Results

We engaged 125 individuals, median age of 33.5 years, with most participants (61 %) deviating significantly during self-testing. Despite this, HIVST was generally perceived as user-friendly. From the perspective of health professionals, there was 100 % agreement between HIVST and the gold standard HIV testing results. Notably, among those seeking solely HIV testing, 19.2 % tested positive for Syphilis, and 4.8 % for Hepatitis C. Only a minority (4.8 %) were aware of the HIV window period.

Conclusion

While HIVST presents benefits, the evidence does not yet support its widespread adoption as a standalone public health policy. Moreover, exclusive reliance on HIVST might mask the prevalence of other STIs. We advocate for a holistic approach to HIV and STI testing, incorporating education, counseling, and comprehensive healthcare access in public health initiatives.

Prevalence and factors associated with knowledge of HIV Self-Test kit and HIV-Self Testing among Ghanaian women: multi-level analyses using the 2022 Ghana demographic and health survey

BACKGROUND

The Ghana AIDS Commission reported in 2022 that out of 354,927 people living with HIV, 67.5% were females. While considerable progress has been made in expanding access to HIV testing services, a significant proportion of individuals remain unaware of their HIV status, presenting a significant barrier to effective prevention and treatment. Although HIV Self-Testing (HIVST) has emerged as a promising approach to increase the uptake of HIV testing, its adoption and utilisation have been limited by various sociodemographic factors. We investigated the knowledge of HIV Self-Testing Kit as well as prevalence of HIVST and their associated factors among Ghanaian women.

METHODS

This was a cross-sectional study among 15,014 women of their reproductive age using data from the 2022 GDHS. The data were analysed using STATA version 17.0. Simple frequencies were used to summarise the data. A multilevel binary logistic regression using four models (Models I-IV) was used to examine the association between the two outcome variables and the explanatory variables, controlling for individual- and contextual-level factors. Statistical significance was set at p < 0.05 at 95% CI.

RESULTS

We discovered that only 18.2% [95% CI = 17.1-19.3] and 2.4% [95% CI = 2.1-2.8] of Ghanaian women in their reproductive age had adequate knowledge of HIV Self-Testing Kit (HIVSTK) and had used the HIVSTK for HIV testing respectively. The odds of knowledge of HIVSTK were higher among women aged 20-24 years (aOR = 1.33, 95% CI = 1.07, 1.64; p = < 0.01), those with a higher level of education (aOR = 6.14, 95% CI = 4.41, 8.55; p < 0.001), those who listen to radio (aOR = 1.41, 95% CI = 1.20, 1.65; p < 0.001) and use the internet at least once a week (aOR = 1.49, 95% CI = 1.24, 1.78; p < 0.001). The odds of knowing about HIVSTKs increased with higher levels of wealth distribution with the highest recorded among those in the wealthiest group (aOR = 1.85, 95% CI = 1.32, 2.58; p < 0.001). Compared with women with no formal education, the odds of HIVST were higher among those with higher education (aOR = 20.29, 95% CI = 9.16, 44.97; p < 0.001). The odds of HIVST were also higher among those who listen to radio (aOR = 1.51, 95% CI = 1.05, 2.17; p < 0.05) and those who use the internet at least once a week [aOR = 1.80, 95% CI = 1.15, 2.83; p < 0.001). Furthermore, the odds of self-testing for HIV were higher among women with a history of HIVST (aOR = 6.73, 95% CI = 3.34, 13.55; p = < 0.001) and those with the wealthiest wealth quintiles (aOR = 4.31, 95% CI = 1.31, 13.02; p = < 0.001).

CONCLUSION

Our study revealed a shallow knowledge of HIV Self-Testing Kit as well as a low prevalence of HIV self-testing among women in their reproductive age in Ghana. The evidence suggests that more than nine in ten women had never undertaken an HIV self-test. The observed HIVST in this study may have implications for achieving the objectives of the HIVST policy. This may impede the achievement of SDG 3.3 which seeks to end the AIDS epidemic by 2030. Practical strategies including education and awareness, may be utilized through electronic media as well as radio and television, especially among those with little or no education. Additionally, the government can subsidise testing kits to create opportunities for those in the low-wealth quintiles to purchase and self-test themselves.

Understanding the cost-utility of implementing HIV self-testing with digital-based supports

Introduction

HIV self-testing (HIVST) is an innovative strategy that has been shown to increase uptake of HIV testing compared to conventional facility-based testing. HIVST implementation with digital-based supports may help facilitate testing accessibility and linkage to care after a reactive self-test. Economic evidence around community-based implementation of HIVST is growing; however, economic evidence around digital-based HIVST approaches remains limited.

Methods

We used previously published cost and efficacy data from HIVST interventions, with the specific intervention model differing between scenarios. Digital-based interventions included text messaging campaigns and online websites that promoted uptake and linkage to HIVST care. Community-based interventions included door-to-door distribution, peer-incentivized distribution, and mobile testing units. Using data obtained from the literature, we parameterized a combined Markov and decision analytic model to evaluate the cost-utility of digital-based HIVST implementation across Malawi, South Africa, and Brazil compared to both community-based HIVST and facility-based testing.

Results

We found that HIVST was cost-effective compared to facility-based testing in all settings investigated. Our scenarios predicted that digital-based HIVST was associated with an incremental cost in the range of $769-$17,839/DALY (disability-adjusted life year) averted compared to facility-based testing across Malawi, South Africa, and Brazil. Digital-based HIVST cost savings had an incremental cost of $7,300/DALY averted compared to community-based HIVST. The main drivers of cost-utility included HIV test and treatment costs, HIV test-positivity, rates of linkage to care, and antiretroviral therapy (ART) initiation rates. Digital-based supports were associated with an increased cost compared to facility-based testing, but they also had increased utility, which led to favorable cost-utility estimates.

Discussion

HIVST with digital supports has the potential to be a highly cost-effective approach, with the potential to make HIV testing more available and accessible, thereby increasing overall uptake and coverage of HIV testing. Digital supports can also support linkage to care, which we have identified as a major driver of cost-utility. Strategies to improve cost-utility include reducing testing costs, targeting key populations with increased rates of HIV test-positivity, and ensuring strong support for linkage to care.

Prevalence, associated factors, barriers and facilitators for oral HIV self-testing among partners of pregnant women attending antenatal care clinics in Wakiso, Uganda

BACKGROUND

Oral HIV self-testing (HIVST) among men is relatively low and still inadequate in Sub-Saharan Africa. Delivering HIVST kits by pregnant women attending antenatal care to their partners is a promising strategy for increasing HIV testing among men. However, even amidst the HIV testing interventions, most men do not know their HIV status. This study, aimed to determine the proportion of partners who received and used oral HIVST kits delivered by pregnant women, associated factors, barriers, and facilitators for uptake.

METHODS

We conducted an exploratory sequential mixed methods study among 380 sampled partners. Lists of partners from HIVST logbooks whose women picked an HIVST kit were obtained and systematic sampling was done to recruit participants. Fourteen (14) male partners were purposively selected for in-depth interviews to identify barriers and facilitators. We used modified poison regression to determine factors associated with oral HIVST. We used an inductive thematic analysis for qualitative analysis.

RESULTS

Out of 380 participants, 260(68.4%) received an oral HIVST kit from their pregnant women, and 215(82.7%) used it for HIVST. Oral HIVST was associated with; Information Education and Communication like availability of HIVST guiding materials (aPR = 1.64, 95%CI: 1.48-1.82), being reached at home (aPR = 1.04, 95%CI 1.01-1.08), and being aware of the woman's HIV status (aPR = 1.04, 95%CI 0.99-1.09). In-depth results identified barriers to uptake as, lack of trust in the HIVST kit results, fear of test outcome in the presence of their partner and inclination that the HIV status of their women is the same as theirs; Facilitators included convenience, ease of use, prior awareness of their HIV status, and fear of relationship consequences and breakup.

CONCLUSION

Delivery of oral HIVST kits to men through pregnant women reached a high number of men and achieved high uptake. Accessing information, education, communication and the kit's convenience were major reasons for uptake among men who received the kit as; trust issues affected its use among partners. Scaling up the delivery of oral HIVST kits at all departments of hospitals through women seeking health services is paramount to support HIV screening among men to reach the UNAIDS 95 strategy.

Exploring HIV Self-Testing: Barriers and Facilitators Among Undergraduate Students in Nairobi, Kenya

PURPOSE

Infection with HIV remains a global health challenge, with >36.9 million individuals living with HIV in 2017. Despite efforts to increase HIV testing and treatment, traditional services have not effectively reached marginalized communities. The use of HIV self-testing (HIVST) offers a discreet and accessible alternative, potentially improving testing rates among at-risk populations including university students in Kenya.

METHODS

We performed a cross-sectional analytical study using a multistage cluster sampling technique among undergraduate students at Kenyatta University. Clusters from various academic departments were randomly selected, and individual students were chosen for participation. Ethical approval was obtained from the Kenyatta University Ethics Review Committee and the National Commission for Science, Technology and Innovation. Participants were informed of the study's aims and their right to withdraw at any time. We collected data via questionnaires administered by trained enumerators.

RESULTS

Participants' age averaged 21.1 years, with a majority being single, female, and full-time students. Substantial HIV knowledge was observed, and nearly one-half were aware of preexposure prophylaxis. Facility-based testing was prevalent, with significant preference for the OraQuick self-test kit among those who self-tested. Fear of positive results and stigma were primary barriers, whereas motivations for self-testing included routine use and protecting loved ones. Media exposure, especially the "Chukua Selfie" campaign, correlated with greater HIVST usage.

CONCLUSIONS

This study highlights the importance of school-based interventions and the critical role of academic institution support in HIV prevention. Participants' substantial knowledge of HIV contrasts with findings from other regions, underscoring the need for targeted education and safe-sex promotion. Addressing fear and stigma via comprehensive interventions is essential for improving HIVST uptake. Integrating HIVST into existing prevention programs can enhance HIV care frameworks in East Africa. Strategies to destigmatize HIV, ensure privacy in testing, and address misconceptions are vital for improving health outcomes among young individuals. Continuous efforts to strengthen self-testing programs are crucial to achieving global HIV targets.

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).

Effectiveness of Using Additional HIV Self-Test Kits as an Incentive to Increase HIV Testing Within Assisted Partner Services

BACKGROUND

Incentives have shown mixed results in increasing HIV testing rates in low-resource settings. We investigated the effectiveness of offering additional self-tests (HIVSTs) as an incentive to increase testing among partners receiving assisted partner services (APS).

SETTING

Western Kenya.

METHODS

We conducted a single-crossover study nested within a cluster-randomized controlled trial. Twenty-four facilities were randomized 1:1 to (1) control: provider-delivered testing or (2) intervention: offered 1 HIVST or provider-delivered testing for 6 months (pre-implementation), then switched to offering 2 HIVSTs for 6 months (post-implementation). A difference-in-differences approach using generalized linear mixed models, accounting for facility clustering and adjusting for age, sex, and income, was used to estimate the effect of the incentive on HIV testing and first-time testing among partners in APS.

RESULTS

March 2021-June 2022, 1127 index clients received APS and named 8155 partners, among whom 2333 reported a prior HIV diagnosis and were excluded from analyses, resulting in 5822 remaining partners: 3646 (62.6%) and 2176 (37.4%) in the pre-implementation and post-implementation periods, respectively. Overall, 944/2176 partners (43%) were offered a second HIVST during post-preimplementation, of whom 34.3% picked up 2 kits, of whom 71.7% reported that the second kit encouraged HIV testing. Comparing partners offered 1 vs. two HIVSTs showed no difference in HIV testing (relative risk: 1.01, 95% confidence interval: 0.951 to 1.07) or HIV testing for the first time (relative risk: 1.23, 95% confidence interval: 0.671 to 2.24).

CONCLUSIONS

Offering a second HIVST as an incentive within APS did not significantly impact HIV testing or first-time testing, although those opting for 2 kits reported it incentivized them to test.

Community-Identified Implementation Strategies for Promoting the Adoption of HIV Self-Testing in a Southern California American Indian community: A Rapid Qualitative Analysis

HIV incidence increased by 18% between 2015 and 2019 among American Indians (AIs) despite declining rates in other racial/ethnic groups. Culturally-appropriate implementation of prevention programs is needed to address the intersectional conditions contributing to HIV vulnerabilities experienced by AIs. The objectives of this study were to understand factors influencing HIV testing decisions and identify implementation strategies to promote the acceptability of HIV self-testing (HIVST) in a southern California AI community. A total of 15 semi-structured interviews were completed with adult community members of a southern California AI reservation. Analysis used a rapid analytic approach that was guided by the Exploration, Preparation, Implementation, Sustainment (EPIS) framework and expert recommendations for implementing change (ERIC) compilation. Two team members applied a standardized summary template to elucidate implementation determinants and implementation strategies for adopting HIVST. Barriers to HIV testing identified by community members included HIV-related stigma and privacy concerns within their community. Community members expressed positive perceptions of the acceptability of HIVST, with many identifying ease of use and privacy as appealing attributes. Several implementation strategies were suggested for facilitating the adoption of HIVST, including increasing access to tests by mailing kits to community members and increasing demand for kits through media campaigns (e.g., local flyers, social media posts, and booths at tribal events). Community members also recommended discreet packaging of kits and cultural adaptation of accompanying materials (e.g., educational videos featuring community members). The qualitative input from AI community members facilitated identification of implementation strategies that may promote the acceptability and culturally-appropriateness of HIVST.

Prevalence, Associated Factors, Barriers and Facilitators for Oral HIV Self-Testing among Partners of Pregnant Women Attending Antenatal Care Clinics in Wakiso, Uganda

Background

Oral HIV self-testing (HIVST) among men is relatively low and still inadequate in Sub-Saharan Africa. Delivering HIVST kits by pregnant women attending antenatal care to their partners is a promising strategy for increasing HIV testing among men. However, even amidst the interventions, most men do not know their HIV status. This study, aimed to determine the proportion of partners who received and used oral HIVST kits delivered by pregnant women, associated factors, barriers, and facilitators for uptake among partners.

Methods

We conducted an exploratory sequential mixed methods study among 380 sampled partners. Lists of partners in the HIVST log books whose women picked an HIVST kit were obtained and systematic random sampling was done to obtain participants. 14 male partners were purposively selected for in-depth interviews (IDIs) to identify barriers and facilitators. We used modified poison regression to determine the association between oral HIVST and independent variables. We used an inductive analysis for the qualitative analysis.

Results

Out of 380 participants, 260(68.4%) received an oral HIVST kit from their pregnant women, and 215(82.7%) used the kit for HIVST. Oral HIVST was associated with; Information Education and Communication (CPR = 1.64, 95%CI 1.48-1.82), being reached at home (CPR = 1.04, 95%CI 1.01-1.08), and being aware of the woman's HIV status (CPR = 1.04, 95%CI 0.99-1.09). In-depth results identified barriers to uptake as, lack of trust in the HIVST kit results, fear of test outcome in the presence of the partner and inclination that the HIV status of their women is the same as theirs, and facilitators included convenience, ease to use, prior awareness of their HIV status, and fear of relationship consequences and breakup.

Conclusion

Delivery of oral HIVST kits to men through pregnant women reached a high number of men and achieved a high uptake. Accessing information, education, communication and convenience nature were the major reasons for uptake among men who received the Oral HIVST kit as trust issues of the kit affected use among partners. Scaling up the delivery of oral HIVST kits at all departments of the hospital through women seeking health services is paramount to support HIV screening among men to reach the UNAIDS 95 strategy.

Country uptake of WHO recommendations on differentiated HIV testing services approaches: a global policy review

OBJECTIVES

In 2015 and 2016, WHO issued guidelines on HIV testing services (HTS) highlighting recommendations for a strategic mix of differentiated HTS approaches. The policy review examines the uptake of differentiated HTS approaches recommendations in national policies.

METHODS

Data were extracted from national policies published between January 2015 and June 2019. The WHO-recommended HTS approaches included facility-based testing, community-based testing, HIV self-testing and provider-assisted referral (or assisted partner notification). Other supportive recommendations include pre-test information, post-test counselling, lay provider testing and rapid testing. Descriptive analyses were conducted to examine inclusion of recommendations in national policies.

RESULTS

Of 194 countries worldwide, 65 published policies were identified; 24 WHO Africa region (AFR) countries (51%, 24/47), 21 WHO European region (EUR) (40%, 21/53), 6 WHO Eastern Mediterranean region (EMR) (29%, 6/21), 5 Pan-American region (AMR) (14%, 5/35), 5 Western Pacific Region (WPR) (19%, 5/27) and 4 WHO South East Asia Region (SEAR) (36%, 4/11). Only five countries included all recommendations. 63 included a minimum of one. 85% (n=55) included facility-based testing for pregnant women, 75% (n=49) facility-based testing for key populations, 74% (n=48) community-based testing for key populations, 69% (n=45) rapid testing, 57% (n=37) post-test counselling, 45% (n=29) lay provider testing, 38% (n=25) HIV self-testing, 29% (n=19) pre-test information and 25% (n=16) provider-assisted referral. The proportion in each region that included at least one recommendation were: 100% AFR (24/47), 100% EMR (6/6), 100% AMR (5/5), 100% WPR (5/5), 100% SEAR (4/4) and 95% EUR (20/21). AFR followed by EMR included the highest number of reccomendations.

CONCLUSION

There was substantial variability in the uptake of the WHO-differentiated HTS recommendations. Those in EMR included the most WHO-differentiated HTS recommendation followed by AFR. Countries within AMR included the least number of recommendations. Ongoing advocacy and efforts are needed to support the uptake of the WHO-differentiated HTS recommendations in country policies as well as their implementation.

Findings From the Todurujo na Kadurok (Empowering Youth) HIV Self-Testing and Edutainment Comic Randomized Controlled Trial With Refugee Youth in a Humanitarian Setting in Uganda

INTRODUCTION

Humanitarian settings are underserved by HIV self-testing (HIV-ST).

METHODS

We conducted a randomized controlled trial to evaluate the effectiveness of HIV-ST (Arm 1), HIV-ST alongside edutainment comics (Arm 2), and edutainment comics (Arm 3), compared with the standard of care (SOC), in increasing HIV testing with refugee youth aged 16-24 in the Bidi Bidi Refugee Settlement, Uganda. Intervention effects on HIV testing at 3-month follow-up (T2) were assessed using generalized estimating equation models alongside open-ended questions.

RESULTS

Retention was 98% (n = 117/120) at T2. In adjusted analyses compared with the SOC, HIV testing changes from baseline to T2 were highest in Arm 2 (adjusted odds ratio [aOR]: 8.46; 95% confidence interval [CI]: 2.87-24.97), followed by Arm 3 (aOR: 4.14; 95% CI: 1.58-10.87), with no significant differences in Arm 1.

CONCLUSION

HIV self-testing is feasible for refugee youth in Uganda and can be supplemented with edutainment comics to advance HIV prevention efforts.

Awareness and willingness to use HIV self-testing among people who inject drugs in Iran

BACKGROUND

Most people who inject drugs (PWID) in Iran have not undergone recent HIV testing. While PWID face barriers when seeking HIV testing at health facilities, HIV self-testing (HIVST) could be a promising approach to improve HIV testing uptake. We examined the awareness and willingness to use HIVST among PWID in Iran. We also identified participants' characteristics associated with a higher willingness to use HIVST.

METHODS

PWID were recruited in 11 cities using a respondent-driven sampling method. Willingness to use HIVST was defined as a binary variable (very low/low willingness vs. high/very high willingness). We performed multivariable modified Poisson regression to examine associated factors and report adjusted prevalence ratios (aPR) and 95% confidence intervals (CI).

RESULTS

Of 2,252 PWID, 362 (16.2%; 95% CI 14.7, 17.8) had ever heard of HIVST; however, 1,658 (73.6%; 95% CI 71.7, 75.4) reported high/very high willingness to use HIVST. Willingness to use HIVST was higher among PWID who reported having a high/moderate HIV risk perception (aPR 1.22; 95% CI 1.09, 1.37), ever experiencing homelessness (aPR 1.15; 95% CI 1.03, 1.28), > 10 years of injecting history (aPR 1.16; 95% CI 1.00, 1.34), and high injection frequency in the last three months (aPR 1.18; 95% CI 1.05, 1.32).

CONCLUSION

Most PWID in Iran, particularly those experiencing homelessness, have a longer injecting history, engage in more frequent injection practices, and possess a heightened perception of HIV risk would be willing to adopt HIVST. Enhancing HIVST awareness through increased access to HIVST and health education programs are needed. Additionally, conducting implementation science studies to effectively design and run HIVST programs in Iran can also increase PWID's access to HIV testing.

Findings from the Tushirikiane mobile health (mHealth) HIV self-testing pragmatic trial with refugee adolescents and youth living in informal settlements in Kampala, Uganda

INTRODUCTION

Urban refugee youth remain underserved by current HIV prevention strategies, including HIV self-testing (HIVST). Examining HIVST feasibility with refugees can inform tailored HIV testing strategies. We examined if HIVST and mobile health (mHealth) delivery approaches could increase HIV testing uptake and HIV status knowledge among refugee youth in Kampala, Uganda.

METHODS

We conducted a three-arm pragmatic controlled trial across five informal settlements grouped into three sites in Kampala from 2020 to 2021 with peer-recruited refugee youth aged 16-24 years. The intervention was HIVST and HIVST + mHealth (HIVST with bidirectional SMS), compared with standard of care (SOC). Primary outcomes were self-reported HIV testing uptake and correct status knowledge verified by point-of-care testing. Some secondary outcomes included: depression, HIV-related stigma, and adolescent sexual and reproductive health (SRH) stigma at three time points (baseline [T0], 8 months [T1] and 12 months [T2]). We used generalized estimating equation regression models to estimate crude and adjusted odds ratios comparing arms over time, adjusting for age, gender and baseline imbalances. We assessed study pragmatism across PRECIS-2 dimensions.

RESULTS

We enrolled 450 participants (50.7% cisgender men, 48.7% cisgender women, 0.7% transgender women; mean age: 20.0, standard deviation: 2.4) across three sites. Self-reported HIV testing uptake increased significantly from T0 to T1 in intervention arms: HIVST arm: (27.6% [n = 43] at T0 vs. 91.2% [n = 135] at T1; HIVST + mHealth: 30.9% [n = 47] at T0 vs. 94.2% [n = 113] at T1]) compared with SOC (35.5% [n = 50] at T0 vs. 24.8% [ = 27] at T1) and remained significantly higher than SOC at T2 (p<0.001). HIV status knowledge in intervention arms (HIVST arm: 100% [n = 121], HIVST + mHealth arm: 97.9% [n = 95]) was significantly higher than SOC (61.5% [n = 59]) at T2. There were modest changes in secondary outcomes in intervention arms, including decreased depression alongside increased HIV-related stigma and adolescent SRH stigma. The trial employed both pragmatic (eligibility criteria, setting, organization, outcome, analysis) and explanatory approaches (recruitment path, flexibility of delivery flexibility, adherence flexibility, follow-up).

CONCLUSIONS

Offering HIVST is a promising approach to increase HIV testing uptake among urban refugee youth in Kampala. We share lessons learned to inform future youth-focused HIVST trials in urban humanitarian settings.

Feasibility and Usability of Mobile Technology to Assist HIV Self-Testing in Youth in Zimbabwe: A Mixed-Methods Study

PURPOSE

Mobile technology is increasingly being used to widen access to and support the delivery of public health interventions. Human immunodeficiency viruses (HIV) self-testing (HIVST) enables individuals to have autonomy. We evaluated the feasibility of a novel application called ITHAKA to support HIVST among youth aged 16-24 years in Zimbabwe.

METHODS

This study was nested within a trial of community-based delivery of integrated HIV and sexual and reproductive health services called CHIEDZA. Youth accessing CHIEDZA were offered provider-delivered HIV testing or HIVST supported by ITHAKA, either on a tablet on-site at a community centre or on their mobile phone off-site. ITHAKA incorporated pre and post-test counselling, and instructions for conducting the test and the appropriate actions to take depending on test result, including reporting HIV test results to health providers. The outcome was completion of the testing journey. Semistructured interviews with CHIEDZA providers explored the perceptions of and experiences with the application.

RESULTS

Between April and September 2019, of the 2,181 youth who accepted HIV testing in CHIEDZA, 128 (5.8%) initiated HIVST (the remainder opting for provider-delivered testing) using ITHAKA. Nearly all who performed HIVST on-site (108/109 (99.1%)) compared to only 9/19 (47.4%) who tested off-site completed their testing journey. Low digital literacy, lack of agency, erratic network coverage, lack of dedicated phone ownership, the limited functionality of smartphones challenged implementation of ITHAKA.

DISCUSSION

Digitally supported HIVST had low uptake among youth. The feasibility and usability of digital interventions should be carefully assessed before implementation, paying careful attention to digital literacy, network availability, and access to devices.

Syphilis

Syphilis is a sexually and vertically transmitted bacterial infection caused by the bacterium Treponema pallidum. Its prevalence is high in low-income and middle-income countries, and its incidence has increased in high-income countries in the last few decades among men who have sex with men. Syphilis is a major cause of adverse pregnancy outcomes in low-income and middle-income countries. Clinical features include a primary chancre at the point of inoculation, followed weeks later by the rash of secondary syphilis, a latent period, and in some cases, involvement of the eyes, CNS, and cardiovascular systems. It is diagnosed serologically. A single intramuscular dose of long-acting benzathine penicillin is recommended for people who have had syphilis for less than 1 year and longer courses for people with late latent syphilis. Control strategies include screening and treatment of all pregnant women, and targeted interventions for groups at high risk. Vaccine development, research on antibiotic prophylaxis, and digital messaging as prevention strategies are ongoing.

Association of anticipated HIV testing stigma and provider mistrust on preference for HIV self-testing among cisgender men who have sex with men in the Philippines

BACKGROUND

New HIV infections in the Philippines are increasing at an alarming rate. However, over three quarters of men who have sex with men (MSM) have never been tested for HIV. HIV self-testing (HIVST) may increase overall testing rates by removing barriers, particularly fear of stigmatization and mistrust of providers. This study aimed to determine if these factors are associated with preference for HIVST among Filipino cisgender MSM (cis-MSM), and whether there is an interaction between anticipated HIV testing stigma and provider mistrust on preference for HIVST.

METHODS

We conducted secondary analysis of a one-time survey of 803 cis-MSM who were recruited using purposive sampling from online MSM dating sites and MSM-themed bar locations in Metro Manila, Philippines. Summary statistics were computed to describe participant characteristics. Multivariable modified Poisson regression analyses were conducted to determine if anticipated HIV testing stigma and provider mistrust were associated with preference for HIVST among cis-MSM. Other variables such as age, education, monthly income, relationship status, HIV serostatus, and knowing where to get HIV testing were the minimal sufficient adjustment set in the analyses.

RESULTS

Average age of participants was 28.6 years (SD = 8.0); most had received college degrees (73%) and were employed (80%). Most respondents (81%) preferred facility-based testing, while 19% preferred HIVST. A high percentage of participants reported anticipated HIV testing stigma (66%) and provider mistrust (44%). Anticipated HIV testing stigma (aPR = 1.51; 95% CI = 1.01-2.25, p = 0.046) and provider mistrust (aPR = 1.49; 95% CI = 1.07-2.09, p = 0.020) were independently associated with a preference for HIVST. There was a positive, additive interaction between provider mistrust and anticipated HIV testing stigma on preference for HIVST (RERI = 1.13, 95% CI: 0.20-2.06; p = 0.017), indicating that the association between anticipated HIV testing stigma and preference for HIVST is greater among those with provider mistrust compared to those without provider mistrust.

CONCLUSIONS

HIVST should be offered as a supplement to traditional facility-based HIV testing services in the Philippines to expand testing and reach individuals who may not undergo testing due to anticipated HIV testing stigma and provider mistrust.

The Feasibility and Acceptability of an mHealth Conversational Agent Designed to Support HIV Self-testing in South Africa: Cross-sectional Study

BACKGROUND

HIV testing rates in sub-Saharan Africa remain below the targeted threshold, and primary care facilities struggle to provide adequate services. Innovative approaches that leverage digital technologies could improve HIV testing and access to treatment.

OBJECTIVE

This study aimed to examine the feasibility and acceptability of Nolwazi_bot. It is an isiZulu-speaking conversational agent designed to support HIV self-testing (HIVST) in KwaZulu-Natal, South Africa.

METHODS

Nolwazi_bot was designed with 4 different personalities that users could choose when selecting a counselor for their HIVST session. We recruited a convenience sample of 120 consenting adults and invited them to undertake an HIV self-test facilitated by the Nolwazi_bot. After testing, participants completed an interviewer-led posttest structured survey to assess their experience with the chatbot-supported HIVST.

RESULTS

Participants (N=120) ranged in age from 18 to 47 years, with half of them being men (61/120, 50.8%). Of the 120 participants, 111 (92.5%) had tested with a human counselor more than once. Of the 120 participants, 45 (37.5%) chose to be counseled by the female Nolwazi_bot personality aged between 18 and 25 years. Approximately one-fifth (21/120, 17.5%) of the participants who underwent an HIV self-test guided by the chatbot tested positive. Most participants (95/120, 79.2%) indicated that their HIV testing experience with a chatbot was much better than that with a human counselor. Many participants (93/120, 77.5%) reported that they felt as if they were talking to a real person, stating that the response tone and word choice of Nolwazi_bot reminded them of how they speak in daily conversations.

CONCLUSIONS

The study provides insights into the potential of digital technology interventions to support HIVST in low-income and middle-income countries. Although we wait to see the full benefits of mobile health, technological interventions including conversational agents or chatbots provide us with an excellent opportunity to improve HIVST by addressing the barriers associated with clinic-based HIV testing.

'When I have these kits … I have confidence' - HIV self-testing provides agency for women in their sexual decision-making

Oral fluid-based HIV self-testing (HIVST) has emerged as a promising approach to increasing HIV testing coverage, particularly among high-risk populations. Understanding the experiences of women using self-tests and offering them to their sexual partners (secondary distribution) is crucial for determining the potential of HIVST. Qualitative in-depth interviews were conducted among 32 women at high risk of HIV infection, including women who engage in transactional sex, who participated in a cluster randomised trial of a secondary distribution strategy in western Kenya. Interviews explored how women used self-tests within relationships and how this affected their sexual decision-making. Three key themes emerged: women used HIVST to assess risk prior to engaging in sex with partners; HIVST provided women with increased agency to engage in or end relationships; and women appreciated these benefits and urged expanded access to self-tests. HIVST has the potential to support HIV prevention objectives in settings with high prevalence of HIV.Trial registration: ClinicalTrials.gov identifier: NCT03135067.

Todurujo na Kadurok (empowering youth): study protocol of an HIV self-testing and edutainment comic cluster randomised trial among refugee youth in a humanitarian setting in Uganda

INTRODUCTION

Refugees experience HIV vulnerabilities due to the confluence of displacement, violence and poverty. HIV self-testing, understudied with refugees, is a promising method to increase testing uptake, yet challenges remain with linkages to confirmatory testing following a positive HIV self-test. This study aims to evaluate the effectiveness of HIV self-testing kits and 'edutainment' comics in increasing HIV testing and HIV status knowledge among refugee youth aged 16-24 years in Bidi Bidi Refugee Settlement, Uganda.

METHODS AND ANALYSIS

This study will be conducted in Bidi Bidi. We conducted a qualitative formative phase with focus groups (n=40) to generate knowledge of barriers and facilitators of HIV prevention, testing and care among refugee youth (aged 16-24) in Bidi Bidi. These findings were used to create comic scenarios aligning with edutainment approaches to health promotion and inform a four-arm cluster randomised controlled trial in Bidi Bidi using a 2×2 factorial design: (1) HIV self-testing alongside edutainment comics, (2) HIV self-testing alone, (3) edutainment comic alone and (4) standard of care. The target sample size will be 120 youth (30 per arm), who will be enrolled in the trial and followed for 3 months. Data will be collected at baseline and 3 months after enrolment. The primary outcomes (HIV testing frequency, HIV status knowledge) and secondary outcomes (linkage to confirmatory HIV testing, HIV care linkage, HIV self-test kit use, HIV-related stigma, HIV knowledge, safer sex efficacy, condom use, adolescent sexual and reproductive health (SRH) stigma, sexual relationship power, access to SRH services) will be evaluated using descriptive statistics and regression analyses.

ETHICS AND DISSEMINATION

This study was approved by the University of Toronto Research Ethics Board, Mildmay Uganda Research Ethics Committee and the Uganda National Council for Science and Technology. Results will be shared in peer-reviewed publications and community knowledge sharing.

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.

Acceptability and perceptions of HIV oral self-testing across settings: A comparative qualitative study among Dominican and Tanzanian female sex workers

Rapid oral HIV self-tests (HIVST) have potential to increase the proportion of people who know their HIV status, especially among stigmatised populations. This study was embedded in two cohorts of female sex workers (FSW) in the Dominican Republic (DR) and Tanzania. Qualitative interviews with 40 FSW were conducted to explore perceived acceptability of HIVST. Interviews were analysed using inductive and deductive thematic coding. Emergent themes were organised by socio-ecological framework levels. FSW in both settings responded positively to the ease of use of HIVST but questioned test accuracy due to the use of saliva rather than blood. FSW in the DR had a more cautious response, while women in Tanzania had favourable perceptions expressing eagerness to use it. At the individual level, themes shaping participants' interest included autonomy, HIV risk perception, and emotional well-being for those with reactive test results, and self-efficacy. At the interpersonal level, privacy, confidentiality, sex work and HIV stigma and social support were salient. Structural level themes focused on health systems including linkages to HIV treatment, provider roles, and access (cost, travel, distribution). Understanding FSW's perceptions and acceptability of HIVST is essential to its integration into health systems and programmes using a community-driven approach.

Understanding socio-sexual networks: critical consideration for HIVST intervention planning among men who have sex with men in Kenya

BACKGROUND

HIV self-testing (HIVST) has emerged as a way of reaching individuals who may be less likely to access testing, including men who have sex with men (MSM). Understanding the social networks of MSM is key to tailoring interventions, such as HIVST, for particular locations.

METHODS

We undertook a socio-sexual network study to characterize and identify patterns of connection among MSM and inform an HIVST intervention in three sites in Kenya. Community researchers in each site selected eight seeds to complete a demographic form and network surveys for 15 each of their sexual and social network members. Seeds recruited three respondents, including two regular service users and one MSM who was "unreached" by the program, who then each identified three respondents, resulting with data on 290 individuals.

RESULTS

Findings illustrate the interconnectedness of community-based organization (CBO) members and non-members. In networks where a majority of members had a CBO membership, members had better contacts with programs and were more likely to have accessed health services. Larger networks had more HIV testing and seeds with frequent testing had a positive influence on their network members also being tested frequently. HIVST was tried in very few networks. Almost all network members were willing to use HIVST.

CONCLUSION

Willingness to use HIVST was nearly universal and points to the importance of networks for reaching individuals not enrolled in programs. Network analysis can help in understanding which type of networks had higher testing and how network-based approaches can be useful to promote HIVST in certain contexts.

HIV and STI Testing Preferences for Men Who Have Sex with Men in High-Income Countries: A Scoping Review

Background: Regular testing for HIV and other sexually transmitted infections (STI) is recommended at least annually for sexually active men who have sex with men (MSM) in most high-income countries. To encourage regular use of HIV and STI testing and treatment services for MSM, we reviewed the literature to summarise the attributes of an HIV/STI testing service that MSM prefer. Method: We conducted a scoping review, searching PubMed, EMBASE, PsycINFO and CINAHL in January 2020 for articles reporting primary data on the preferences of MSM (living in high-income countries) for HIV/STI testing services. Two reviewers independently screened titles and abstracts and any discrepancies were resolved by a third reviewer. We extracted data on the service attributes that MSM preferred and summarised these thematically using a socioecological framework. Results: In total, 1464 publications were identified, 220 full texts were read and 57 were included in the final analysis. We found 21 articles addressing 'individual' attributes, 50 articles addressing 'service' attributes and 17 articles addressing 'societal' attributes. The key themes of preferences for HIV/STI testing services were: (1) the appeal of self-testing due to convenience and privacy; (2) the need to provide a variety of testing options; and (3) the influence of the testing experience, including confidentiality and privacy, tester characteristics and stigma. There were distinct patterns of preferences for subpopulations of MSM across studies, such as the preference of self-testing for young MSM, and of in-clinic testing for those who perceived themselves as high risk (i.e., with symptoms of STIs or exposed to a partner living with HIV). Conclusion: To make HIV/STI testing more accessible for MSM and encourage regular screening, it is important to address 'individual', 'service' and 'societal' attributes, such as enhancing the convenience of testing through self-testing, and providing a service that men feel comfortable and safe accessing. Furthermore, services should accommodate the preferences of diverse sub-populations within the MSM community.

Expanding syphilis test uptake using rapid dual self-testing for syphilis and HIV among men who have sex with men in China: A multiarm randomized controlled trial

BACKGROUND

Low syphilis testing uptake is a major public health issue among men who have sex with men (MSM) in many low- and middle-income countries. Syphilis self-testing (SST) may complement and extend facility-based testing. We aimed to evaluate the effectiveness and costs of providing SST on increasing syphilis testing uptake among MSM in China.

METHODS AND FINDINGS

An open-label, parallel 3-arm randomized controlled trial (RCT) was conducted between January 7, 2020 and July 17, 2020. Men who were at least 18 years of age, had condomless anal sex with men in the past year, reported not testing for syphilis in the last 6 months, and had a stable residence with mailing addresses were recruited from 124 cities in 26 Chinese provinces. Using block randomization with blocks of size 12, enrolled participants were randomly assigned (1:1:1) into 3 arms: standard of care arm, standard SST arm, and lottery incentivized SST arm (1 in 10 chance to win US$15 if they had a syphilis test). The primary outcome was the proportion of participants who tested for syphilis during the trial period and confirmed with photo verification and between arm comparisons were estimated with risk differences (RDs). Analyses were performed on a modified intention-to-treat basis: Participants were included in the complete case analysis if they had initiated at least 1 follow-up survey. The Syphilis/HIV Duo rapid test kit was used. A total of 451 men were enrolled. In total, 136 (90·7%, 136/150) in the standard of care arm, 142 (94·0%, 142/151) in the standard of SST arm, and 137 (91·3%, 137/150) in the lottery incentivized SST arm were included in the final analysis. The proportion of men who had at least 1 syphilis test during the trial period was 63.4% (95% confidence interval [CI]: 55.5% to 71.3%, p = 0.001) in the standard SST arm, 65.7% (95% CI: 57.7% to 73.6%, p = 0.0002) in the lottery incentivized SST arm, and 14.7% (95% CI: 8.8% to 20.7%, p < 0.001) in the standard of care arm. The estimated RD between the standard SST and standard of care arm was 48.7% (95% CI: 37.8% to 58.4%, p < 0.001). The majority (78.5%, 95% CI: 72.7% to 84.4%, p < 0.001) of syphilis self-testers reported never testing for syphilis. The cost per person tested was US$26.55 for standard SST, US$28.09 for the lottery incentivized SST, and US$66.19 for the standard of care. No study-related adverse events were reported during the study duration. Limitation was that the impact of the Coronavirus Disease 2019 (COVID-19) restrictions may have accentuated demand for decentralized testing.

CONCLUSIONS

Compared to standard of care, providing SST significantly increased the proportion of MSM testing for syphilis in China and was cheaper (per person tested).

HIV testing frequency and associated factors among five key populations in ten cities of China: a cross-sectional study

BACKGROUND

Regular HIV testing is the best way to detect people living with HIV promptly, yet not much is known about the characteristics of frequent, voluntary testers. This study explores factors related to HIV testing frequency among five key populations in China including men who have sex with men (MSM), female sex workers (FSWs), people who use drugs (PWUD), men who have casual sex with women (MCSW) and sero-negative partners among sero-discordant couples (SNPs).

METHODS

We conducted a cross-sectional study in ten cities of China from November 2018 to September 2019 using convenience sampling to recruit participants. Univariate and multivariate partial proportional odds models were adopted to compare socio-behavioral factors associated with HIV testing frequencies among the five key populations.

RESULTS

Among the 2022 recruited participants, 36.6% reported not testing for HIV in the past year, whereas 37.0% tested once and 26.4% tested twice. Compared with MSM, FSWs (AOR = 1.97, 95% CI: 1.36-2.86) and SNPs (AOR = 3.63, 95% CI: 2.40-5.49) were more likely to test for HIV, but MCSW (AOR = 0.23, 95% CI: 0.17-0.32) were less likely. Additionally, SNPs (AOR = 4.02, 95% CI: 2.78-5.83) were more likely to be frequent HIV testers, while FSWs (AOR = 0.49, 95% CI: 0.32-0.76) and MCSW (AOR = 0.29, 95% CI: 0.20-0.41) were less likely to be frequent testers. Factors identified as barriers to HIV testing include the following: higher education level and > 5000 CNY monthly income for FSWs; elder age and a married/cohabitating status for PWUD; reported alcohol use for MCSW; and non-Han ethnicity and non-local household for SNPs. Facilitators to frequent testing included the following: higher education level for MSM and SNPs; higher AIDS knowledge score for MSM and PWUD; > 5000 CNY monthly income for FSWs and PWUD; and reporting high-risk sexual behaviors for MSM, FSW and PWUD.

CONCLUSIONS

HIV testing frequencies and associated factors were not equivalent across the five key populations in China. Public health officials should take heed of the identified high-risk populations reporting high testing rates, perhaps with intensive and tailored behavioral interventions or biochemical prophylaxis.

Remaking the Technosubject: Kenyan Men Contextualizing HIV Self-Testing Technologies

The Kenyan government offers free HIV self-testing kits to men who have sex with men. The value of self-testing is based on the imaginary of an autonomous technosubject empowered to independently control testing services, thereby "freed," through technology, from the social conditions that might inhibit health services utilization. Following a community-centered collaborative approach, community researchers interviewed their peers who examined and reacted to the technology. Participants reframed the technosubject as intertwined with the social world and the testing kit itself as an object that exerts agency and possesses affective potential. Attending to these socio-material relationalities offers insights into program planning.

Frameworks, measures, and interventions for HIV-related internalised stigma and stigma in healthcare and laws and policies: systematic review protocol

INTRODUCTION

There is strong global commitment to eliminate HIV-related stigma. Wide variation exists in frameworks and measures, and many strategies to prevent, reduce or mitigate stigma have been proposed but critical factors determining success or failure remain elusive.

METHODS AND ANALYSIS

Building on existing knowledge syntheses, we designed a systematic review to identify frameworks, measures and intervention evaluations aiming to address internalised stigma, stigma and discrimination in healthcare, and stigma and discrimination at the legal or policy level. The review addresses four key questions (KQ): KQ1: Which conceptual frameworks have been proposed to assess internal stigma, stigma and discrimination experienced in healthcare settings, and stigma and discrimination entrenched in national laws and policies? KQ2: Which measures of stigma have been proposed and what are their descriptive properties? KQ3: Which interventions have been evaluated that aimed to reduce these types of stigma and discrimination or mitigate their adverse effects and what are the effectiveness and unintended consequences? KQ4: What common 'critical factors for success or failure' can be identified across interventions that have been evaluated? We will search PubMed, PsycINFO, Web of Science, Universal Human Rights Index, HeinOnline, PAIS, HIV Legal Network, CDSR, Campbell Collaboration, PROSPERO and Open Science Framework. Critical appraisal will assess the source, processes and consensus finding for frameworks; COnsensus-based Standards for the selection of health Measurement Instruments criteria for measures; and risk of bias for interventions. Quality of evidence grading will apply . A gap analysis will provide targeted recommendations for future research. We will establish a compendium of frameworks, a comprehensive catalogue of available measures, and a synthesis of intervention characteristics to advance the science of HIV-related stigma.

The COVID-19 Self-Testing through Rapid Network Distribution (C-STRAND) trial: A randomized controlled trial to increase COVID-19 testing in underserved populations

Background Widely available population testing is critical to public health efforts to control the ongoing COVID-19 pandemic. However, COVID-19 testing has been low in underserved communities disproportionately affected by COVID-19. One approach to increase testing rates is through the secondary distribution of self-collection kits, where an individual distributes test kits to contacts in their social network and encourages them to self-collect test specimens. We outline a randomized clinical trial, COVID-19 Self-testing Through Rapid Network Distribution (C-STRAND), and a cohort study of individuals with COVID-19, to determine the impact of a secondary distribution strategy on COVID-19 testing among medically underserved populations. Methods The clinical trial will seek to enroll 1048 adult index participants from federally health qualified centers in Philadelphia, PA seeking COVID-19 testing. Eligible participants will be randomized 1:1 to receive multiple self-collection test kits or multiple referrals for standard clinic-based tests to distribute to contacts within their social network. The primary outcome will be testing among at least two network contacts at 8 weeks. Index participants and network contacts who test positive for COVID-19 from C-STRAND will be eligible to join the COVID-19 Close Contact Self-testing Study (CloseST), assessing the secondary distribution of self-collection test kits among individuals with COVID-19. The primary outcome of this cohort will be the number of close contacts who test positive at 8 weeks. Conclusion Novel strategies to promote COVID-19 testing are necessary, particularly among underserved populations most affected by COVID-19. We will determine the efficacy of a self-testing secondary distribution strategy. The results may inform efforts to increase testing rates during the current pandemic.

The longer-term effects of access to HIV self-tests on HIV testing frequency in high-risk gay and bisexual men: follow-up data from a randomised controlled trial

Background

A wait-list randomised controlled trial in Australia (FORTH) in high-risk gay and bisexual men (GBM) showed access to free HIV self-tests (HIVSTs) doubled the frequency of HIV testing in year 1 to reach guideline recommended levels of 4 tests per year, compared to two tests per year in the standard-care arm (facility-based testing). In year 2, men in both arms had access to HIVSTs. We assessed if the effect was maintained for a further 12 months.

Methods

Participants included GBM reporting condomless anal intercourse or > 5 male partners in the past 3 months. We included men who had completed at least one survey in both year 1 and 2 and calculated the mean tests per person, based on the validated self-report and clinic records. We used Poisson regression and random effects Poisson regression models to compare the overall testing frequency by study arm, year and testing modality (HIVST/facility-based test).

Findings

Overall, 362 men completed at least one survey in year 1 and 343 in year 2. Among men in the intervention arm (access to HIVSTs in both years), the mean number of HIV tests in year 2 (3⋅7 overall, 2⋅3 facility-based tests, 1⋅4 HIVSTs) was lower compared to year 1 (4⋅1 overall, 1⋅7 facility-based tests, 2⋅4 HIVSTs) (RR:0⋅84, 95% CI:0⋅75-0⋅95, p=0⋅002), but higher than the standard-care arm in year 1 (2⋅0 overall, RR:1⋅71, 95% CI:1⋅48-1.97, p<0⋅001). Findings were not different when stratified by sociodemographic characteristics or recent high risk sexual history.

Interpretation

In year 2, fewer HIVSTs were used on average compared to year 1, but access to free HIVSTs enabled more men to maintain higher HIV testing frequency, compared with facility-based testing only. HIV self-testing should be a key component of HIV testing and prevention strategies.

HIV self-testing with digital supports as the new paradigm: A systematic review of global evidence (2010-2021)

BACKGROUND

HIV self-testing (HIVST) is recommended by the WHO as an innovative strategy to reach UNAIDS targets to end HIV by 2030. HIVST with digital supports is defined as the use of digital interventions (e.g., website-based, social media, mobile HIVST applications (apps), text messaging (SMS), digital vending machines (digital VMs)) to improve the efficiency and impact of HIVST. HIVST deployment and integration in health services is an emerging priority. We conducted a systematic review aiming to close the gap in evidence that summarizes the impact of digitally supported HIVST and to inform policy recommendations.

METHODS

We searched PubMed and Embase for articles and abstracts on HIVST with digital supports published during the period February 1st, 2010 to June 15th, 2021, following Cochrane guidelines and PRISMA methodology. We assessed feasibility, acceptability, preference, and impact outcomes across all populations and study designs. Metrics reported were willingness to use HIVST, preferences for HIVST delivery, proportion of first-time testers, HIVST uptake, HIVST kit return rate, and linkage to care. Heterogeneity of the interventions and reported metrics precluded us from conducting a meta-analysis.

FINDINGS

46 studies were narratively synthesized, of which 72% were observational and 28% were RCTs. Half of all studies (54%, 25/46) assessed web-based innovations (e.g., study websites, videos, chatbots), followed by social media (26%, 12/46), HIVST-specific apps (7%, 3/46), SMS (9%, 4/46), and digital VMs (4%, 2/46). Web-based innovations were found to be acceptable (77-97%), preferred over in-person and hybrid options by more first-time testers (47-48%), highly feasible (93-95%), and were overall effective in supporting linkage to care (53-100%). Social media and app-based innovations also had high acceptability (87-95%) and linkage to care proportions (80-100%). SMS innovations increased kit return rates (54-94%) and HIVST uptake among hard-to-reach groups. Finally, digital VMs were highly acceptable (54-93%), and HIVST uptake was six times greater when using digital VMs compared to distribution by community workers.

INTERPRETATION

HIVST with digital supports was deemed feasible, acceptable, preferable, and was shown to increase uptake, engage first-time testers and hard-to-reach populations, and successfully link participants to treatment. Findings pave the way for greater use of HIVST interventions with digital supports globally.

Uptake of oral fluid-based HIV self-testing among men who have sex with men and transgender women in Thailand

Background

Suboptimal uptake of HIV testing remains a primary bottleneck to HIV prevention and treatment for men who have sex with men (MSM) and transgender women (TGW) in Thailand. The World Health Organization has recommended HIV self-testing (HIVST) as an additional strategic HIV service. However, HIVST has not been fully endorsed and implemented in many countries in Southeast Asia. The aim of this study was to assess the uptake of oral fluid-based HIVST in MSM and TGW populations in Thailand.

Methods

During 2017 and 2018, we conducted a cross-sectional study using convenience sampling to enroll 2,524 participants from three major urban areas. Participants were recruited during outreach and online activities and were offered unassisted or assisted HIVST, or referral to HIV testing services. A descriptive analysis was performed for summarizing data.

Results

A total of 2,502 participants (1,422 MSM and 1,082 TGW) were included in the analysis with about one-third (36.1%) of them being first-time testers. Among all participants enrolled in the study, a total of 2,486 participants (99.3%) selected HIVST versus referral to HIV testing services. Of those who selected HIVST, 2,095 (84.3%) opted for assisted HIVST while the rest opted for unassisted HIVST: 1,148 of 1,411 MSM (81.4%) and 947 of 1,075 TGW (88.1%) selected assisted HIVST. While no serious adverse events were reported during the study, we found that among 179 participants who needed a confirmatory test and were referred to HIV testing services, 108 (60.3.4%) accessed these later services.

Conclusions

This study demonstrated a high uptake of oral fluid-based HIVST among MSM and TGW populations in Thailand and that HIVST could be scaled up through the national epidemic control program. However, a better understanding of HIV testing-seeking behavior and innovative follow-up solutions are needed to improve and monitor linkages to services for people who undertake HIVST.

Impact of a personalised, digital, HIV self-testing app-based program on linkages and new infections in the township populations of South Africa

INTRODUCTION

Implementation data for digital unsupervised HIV self-testing (HIVST) are sparse. We evaluated the impact of an app-based, personalised, oral HIVST program offered by healthcare workers in Western Cape, South Africa.

METHODS

In a quasirandomised study (n=3095), we recruited consenting adults with undiagnosed HIV infection from township clinics. To the HIVST arm participants (n=1535), we offered a choice of an offsite (home, office or kiosk based), unsupervised digital HIVST program (n=962), or an onsite, clinic-based, supervised digital HIVST program (n=573) with 24/7 linkages services.With propensity score analyses, we compared outcomes (ie, linkages, new HIV infections and test referrals) with conventional HIV testing (ConvHT) arm participants (n=1560), recruited randomly from geographically separated clinics.

RESULTS

In both arms, participants were young (HIVST vs ConvHT) (mean age: 28.2 years vs 29.2 years), female (65.0% vs 76.0%) and had monthly income <3000 rand (80.8% vs 75%).Participants chose unsupervised HIVST (62.7%) versus supervised HIVST and reported multiple sex partners (10.88% vs 8.7%), exposure to sex workers (1.4% vs 0.2%) and fewer comorbidities (0.9% vs 1.9%). Almost all HIVST participants were linked (unsupervised HIVST (99.7%), supervised HIVST (99.8%) vs ConvHT (98.5%)) (adj RR 1.012; 95% CI 1.005 to 1.018) with new HIV infections: overall HIVST (9%); supervised HIVST (10.9%) and unsupervised HIVST (7.6%) versus ConvHT (6.79%) (adj RR 1.305; 95% CI 1.023 to 1.665); test referrals: 16.7% HIVST versus 3.1% ConvHT (adj RR 5.435; 95% CI 4.024 to 7.340).

CONCLUSIONS

Our flexible, personalised, app-based HIVST program, offered by healthcare workers, successfully linked almost all HIV self-testers, detected new infections and increased referrals to self-test. Data are relevant for digital HIVST initiatives worldwide.

Community-Based Interventions as Opportunities to Increase HIV Self-Testing and Linkage to Care Among Men Who Have Sex With Men - Lessons From Ghana, West Africa

MSM in Ghana encounter challenges in accessing HIV services and may experience barriers to HIV self-testing due to multiple forms of stigma present in health care settings. We worked with community-based organization partners to implement three interventions that successfully engaged and retained MSM which provides an opportunity for linkage to self-testing and medical care. These interventions were (1) Many Men Many Voices (3MV) a locally-led culturally grounded group-level HIV prevention program, (2) Auntie's Corner: a mobile-app based connecting MSM to health monitoring by a registered nurse and (3) HIV Education, Empathy, & Empowerment (HIVE3): a mobile-app based peer support intervention for MSM living with HIV. The 3MV intervention may be effective in improving HIV self-testing due to its effectiveness in engaging MSM, increasing HIV testing, and improving MSM understanding of the need for HIV testing. The utilization of apps like Auntie's Corner could positively impact HIV self-testing among MSM because it increases contact with nurses and reporting of symptoms. In HIVE3, participants expressed appreciation of the security and privacy that protects their identities as MSM and the peer mentors' abilities to make referrals to the nurses in Auntie's Corners. The confidentiality component has proven key among MSM and connecting MSM to self-testing through apps to report their process and receive care could increase utilization. Together, we show the efficacy of using the community-engaged process in reaching and engaging highly stigmatized populations like Ghana and sub-Saharan Africa, and its potential in increasing HIV self-testing and linkage to HIV care.

At-home HIV self-testing during COVID: implementing the GetaKit project in Ottawa

Setting

In March 2020, COVID-19 shuttered access to many healthcare settings offering HIV testing and there is no licensed HIV self-test in Canada.

Intervention

A team of nurses at the University of Ottawa and Ottawa Public Health and staff from the Ontario HIV Treatment Network (OHTN) obtained Health Canada’s Special Access approval on April 23, 2020 to distribute bioLytical’s INSTI HIV self-test in Ottawa; we received REB approval on May 15, 2020. As of July 20, 2020, eligible participants (≥18 years old, HIV-negative, not on PrEP, not in an HIV vaccine trial, living in Ottawa, no bleeding disorders) could register via www.GetaKit.ca to order kits.

Outcomes

In the first 6 weeks, 637 persons completed our eligibility screener; 43.3% (n = 276) were eligible. Of eligible participants, 203 completed a baseline survey and 182 ordered a test. These 203 participants were an average of 31 years old, 72.3% were white, 60.4% were cis-male, and 55% self-identified as gay. Seventy-one percent (n = 144) belonged to a priority group for HIV testing. We have results for 70.9% (n = 129/182) of participants who ordered a kit: none were positive, 104 were negative, 22 were invalid, and 2 “preferred not to say”; 1 participant reported an unreadiness to test.

Implications

Our results show that HIV self-testing is a pandemic-friendly strategy to help ensure access to sexual health services among persons who are good candidates for HIV testing. It is unsurprising that no one tested positive for HIV thus far, given the 0.08% positivity rate for HIV testing in Ottawa. As such, we advocate for scale-up of HIV self-testing in Canada.

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.

Syphilis self-testing to expand test uptake among men who have sex with men: a theoretically informed mixed methods study in Zimbabwe

Objectives

Self-testing for STIs such as HIV and syphilis may empower sexual minorities and expand uptake of STI testing. While much is known about HIV self-testing (HIVST), less is known about syphilis self-testing, particularly in low-income settings. The objective of this study is to determine context-specific facilitators and barriers for self-testing and to assess the usability of syphilis self-testing in Zimbabwe among men who have sex with men (MSM).

Methods

This mixed methods study was conducted in Harare as part of a larger syphilis self-testing trial. The study included in-depth interviews (phase I) followed by usability testing and a second interview (phase II). In-depth interviews were conducted with MSM and key informants prior to syphilis self-testing. The same MSM then used the syphilis self-test, quantitatively assessed its usability and participated in a second in-depth interview. Phase I data were analysed using a thematic approach, guided by an adapted social ecological model conceptual framework. Phase II interviews were analysed using rapid assessment procedure methodology, and usability was assessed using a pre-established index, adapted from existing HIVST scales.

Results

Twenty MSM and 10 key informants were recruited for phase I in-depth interviews, and 16 of these MSM participated in phase II by completing a syphilis self-test kit. Facilitating factors for self-testing included the potential for increased privacy, convenience, autonomy, and avoidance of social and healthcare provider stigma. Barriers included the fear to test and uncertainty about linkage to care and treatment. Data from the Usability Index suggested high usability (89.6% on a 0–100 scale) among the men who received the self-test.

Conclusions

MSM in Zimbabwe were willing to use syphilis self-test kits and many of the barriers and facilitators were similar to those observed for HIVST. Syphilis self-testing may increase syphilis test uptake among sexual minorities in Zimbabwe and other low-income and middle-income countries.

Syphilis Self-testing: A Nationwide Pragmatic Study Among Men Who Have Sex With Men in China

BACKGROUND

Syphilis self-testing may help expand syphilis testing among men who have sex with men (MSM). China has rapidly scaled up human immunodeficiency virus (HIV) self-testing, creating an opportunity for integrated syphilis self-testing. However, there is a limited literature on implementing syphilis self-testing.

METHODS

A cross-sectional online survey was conducted among Chinese MSM in 2018. Participants completed a survey instrument including sociodemographic characteristics, sexual behaviors, syphilis self-testing, and HIV self-testing history. Multivariable logistic regression was conducted to identify correlates of syphilis self-testing. We also recorded potential harms associated with syphilis self-testing.

RESULTS

Six hundred ninety-nine MSM from 89 cities in 21 provinces in China completed the study. A total of 361/699 (51.7%) men tested for syphilis, of whom 174/699 (24.9%) men used syphilis self-testing. Among 174 who had self-tested, 90 (51.7%) reported that the self-test was their first syphilis test and 161 (92.5%) reported that they undertook syphilis self-testing together with HIV self-testing. After adjusting for covariates, syphilis self-testing was correlated with disclosure of sexual orientation to family or friends (adjusted odds ratio [aOR], 1.90; 95% confidence interval [CI], 1.32-2.73), reporting 2-5 male sexual partners (aOR, 1.81; 95% CI, 1.04-3.16), HIV self-testing (aOR, 39.90; 95% CI, 17.00-93.61), and never tested for syphilis in the hospital (aOR, 2.96; 95% CI, 1.86-4.72). Self-reported harms associated with syphilis self-testing were minimal.

CONCLUSIONS

Scaling up syphilis self-testing could complement facility-based testing in China among MSM. Self-testing may increase first-time testing and has limited harms. Our findings suggest that syphilis self-testing could be integrated into HIV self-testing services.

A Scoping Review of Patient Preferences for HIV Self-Testing Services in the United States: Implications for Harm Reduction

PURPOSE

Despite marked progress in the ability to test for, treat, and prevent HIV, the epidemic remains a significant public health concern, especially among key populations including prisoners; sex workers; transgender individuals; gay, bisexual, and other men who have sex with men (MSM); and Black and Latinx MSM. This scoping review was conducted to provide an overview of the current research describing patient preferences for HIVST in the United States to understand what key populations value about HIVST and why they are willing to use it. A targeted search for published literature on patient preferences for HIVST was conducted using Ovid Medline, PsychINFO, and an HIVST research database.

RESULTS

We reviewed 700 abstracts and 139 full texts. We found 19 articles published between January 2014 and April 2020 that included findings related to HIVST preferences. Overall, HIVST was preferred to more traditional testing. Six primary factors emerged as important HIVST values including: 1) convenience, 2) type of test; 3) cost, 4) stigma reduction, 5) risk reduction, and 6) self-control. Linkage to care was also identified as a key factor when considering HIVST as an option. Much of what makes HIVST attractive to individuals is their ability to self-determine how HIVST can be best integrated into their lives as a harm reduction tool for stigma and sexual risk mitigation.

CONCLUSION

While there is substantial evidence suggesting HIVST is feasible for use and there are aspects of HIVST that are beneficial and preferred over traditional testing approaches, there is a lack of rigorous implementation studies exploring how best to scale up HIVST in community settings. HIVST has the potential to be a powerful biobehavioral HIV prevention and harm reduction tool to empower individuals to engage with testing on their own terms while providing pathways to prevention and care support.

Self-care interventions for sexual and reproductive health and rights for advancing universal health coverage

WHO's normative guidance on self-care interventions for sexual and reproductive health and rights (SRHR) promotes comprehensive, integrated and people-centred approaches to health service delivery. Implementation of self-care interventions within the context of human rights, gender equality, and a life course approach, offers an underused opportunity to improve universal health coverage (UHC) for all. Results from an online global values and preferences survey provided lay persons' and healthcare providers' perspectives on access, acceptability, and implementation considerations. This analysis examines 326 qualitative responses to open-ended questions from healthcare providers (n = 242) and lay persons (n = 70) from 77 countries. Participants were mostly women (66.9%) and were from the Africa (34.5%), America (32.5%), South-East Asia (5.6%), European (19.8%), Eastern Mediterranean (4.8%), and Western Pacific regions (2.8%). Participants perceived multiple benefits of self-care interventions for SRHR, including: reduced exposure to stigma, discrimination and access barriers, increased confidentiality, empowerment, self-confidence, and informed decision-making. Concerns include insufficient knowledge, affordability, and possible side-effects. Implementation considerations highlighted the innovative approaches to linkages with health services. Introduction of self-care interventions is a paradigm shift in health care delivery bridging people and communities through primary health care to reach UHC. Self-care interventions can be leveraged by countries as gateways for reaching more people with quality, accessible and equitable services that is critical for achieving UHC. The survey results underscored the urgent need to reduce stigma and discrimination, increase access to and improve knowledge of self-care interventions for SRHR for laypersons and healthcare providers to advance SRHR.

Employers' and Employees' Perspectives of HIV Self-Testing at Male-Dominated Work Sites and Linkage to Posttest Services in Uganda

This study explored men's views of workplace-based HIV self-testing and the barriers and facilitators of linkage to posttest services. Six focus group discussions and individual in-depth interviews were held with employers and employees in private security companies in Uganda (N = 70). Using content analysis, five categories emerged. The first category was the mitigation of potential harm, including reduction of stigma and discrimination, and the need for posttest support. The second category was a perceived need for on-site services where the men proposed on-site prevention services and HIV treatment and care. In the third category, which was strengthening linkage mechanisms, participants proposed expanded clinic hours, improved health facility efficiency, and provision of referral documentation. The fourth and fifth categories were organizational support and social support, respectively. There is need for employers and employees to work together for the success of workplace-based HIV initiatives.

A qualitative study on oral-fluid-based HIV self-testing experiences among men in Kigali, Rwanda

Introduction

there has been a global call to engage men in the fight against the HIV epidemic. Poor uptake of HIV testing services among men has been reported in most of sub-Saharan Africa where the HIV epidemic continues to be a major public health problem. HIV self-testing (HIVST) has potential to bridge the gap; however, there is a paucity of research evidence on oral-fluid-based HIVST experiences among men in Rwanda. The aim of this study was to assess oral-fluid-based HIVST experiences among men.

Methods

a qualitative study based on individual interviews was employed on 21 men who voluntarily obtained oral-fluid-based HIV self-test kits and consented for follow-up post-test interviews. Interview guides explored men´s perspectives on the oral-fluid-based HIV self-screening experience. A conventional content analysis qualitative approach was adopted, entailing inductive thematic analysis.

Results

the majority of participants expressed satisfaction with the experience of self-testing, citing privacy and turn-around time. Participants presented contradicting views on usability of test kits and post-test status disclosure to sexual partners. One participant reported post-test distress resulting from unexpected results.

Conclusion

HIVST is attractive to men and may have potential for improving uptake of HIV testing services in this group without compromising the testing experience. Concerns on missing linkage to care and potential social harms and adverse events should not be ignored.

A Systematic Review of Technology-Assisted HIV Testing Interventions

PURPOSE OF REVIEW

The purpose of this review is to describe and assess the literature on mobile health (mHealth) and other technology-based HIV testing interventions published in the 5-year period from 2015 to 2020.

RECENT FINDINGS

We identified 18 published technology-based studies, 6 of which were efficacy trials and the remaining 12 were either pilot randomized controlled trials (RCTs) or quasi-experimental studies. Most (n = 10) interventions were conducted outside the USA, including countries in Sub-Saharan Africa (n = 4), China (n = 3), Latin America (n = 2), and India (n = 1). All efficacy trials showed some evidence of efficacy, although uptake of HIV testing was low among in intervention trials that consisted of a low number of text messages. Most pilot RCTs demonstrated high levels of feasibility and acceptability, as well as some evidence that the intervention participants benefited more than the control group. Many non-randomized trials similarly reported positive appraisal by study participants. Recommendations for future research and practice by the authors of the studies reviewed here are summarized. Technology-assisted HIV testing interventions may be an important strategy to reach national and global targets for HIV status awareness in the general population and for most at-risk groups. Although there appears to be growing evidence of their benefit, questions linger regarding how to leverage existing social media platforms to promote HIV testing, which interventions work for what populations, and best practices for scaling up mHealth and other technology-based interventions.

Acceptability of oral HIV self-testing among female sex workers in Gaborone, Botswana

Background

HIV prevalence among female sex workers (FSW) in sub-Saharan Africa is much higher than in the general population. HIV self-testing (HIVST) may be useful for increasing testing rates in FSW.

Methods

We conducted semi-structured in-depth interviews among FSW, nurses and lay counsellors providing services to FSWs in Botswana. We aimed to gain understanding of perceived acceptability, anticipated barriers, and preferred approaches to HIVST among FSW. Interviews were audio-recorded, transcribed and translated. Transcripts were reviewed and coded independently by two investigators; high inter-coder agreement was achieved (Kappa = 0.80).

Results

We interviewed five care providers whose average age was 40 years (SD = 2,64, range = 37–43); three nurses and two counsellors. Thirty FSW were interviewed, with mean age 34 years (range = 20–52). Most (27; 90%) FSW expressed great interest in using HIVST kits. Facilitators of HIVST were: awareness of own risky sexual behaviours, desire to stay healthy, and perceived autonomy over one’s healthcare decisions. Perceived advantages of HIVST included convenience, privacy, and perception of decreased stigma. Identified barriers to HIVST included lack of knowledge about the HIVST kit, fear of testing due to anticipated stigma, mistrust of the test’s accuracy, doubt of self-competency to perform HIVST, and concerns about not linking to care. Assisting someone to test was noted as good for providing emotional support, but there were concerns about confidentiality breaches. Providers expressed concerns over low literacy among FSWs which could affect comprehension of testing instructions, and competency to perform testing and interpret results. Participants’ recommendations for implementation of HIVST included: ensuring wide dissemination of information on HIVST, engaging peers in information-sharing and education, making test kits accessible in FSW-friendly centres, and having clear instructions for linkage to healthcare and support.

Conclusion

HIVST shows high acceptability among FSWs in Gaborone Botswana, with providers expressing some concerns. Implementation should be peer-driven with healthcare provider oversight.

Promoting routine syphilis screening among men who have sex with men in China: study protocol for a randomised controlled trial of syphilis self-testing and lottery incentive

BACKGROUND

Men who have sex with men (MSM) bear a high burden of syphilis infection. Expanding syphilis testing to improve timely diagnosis and treatment is critical to improve syphilis control. However, syphilis testing rates remain low among MSM, particularly in low- and middle-income countries. We describe the protocol for a randomised controlled trial (RCT) to assess whether provision of syphilis self-testing services can increase the uptake of syphilis testing among MSM in China.

METHODS

Four hundred forty-four high-risk MSM will be recruited online and randomized in a 1:1:1 ratio to (1) standard syphilis self-testing arm; (2) a self-testing arm program enhanced with crowdsourcing and a lottery-based incentive, and (3) a standard of care (control). Self-testing services include a free syphilis self-test kit through the mail at monthly intervals. Participants in the lottery incentive arm will additionally receive health promotion materials generated from an open crowdsourcing contest and be given a lottery draw with a 10% chance to win 100 RMB (approximately 15 US Dollars) upon confirmed completion of syphilis testing. Syphilis self-test kits have step-by-step instructions and an instructional video. This is a non-blinded, open-label, parallel RCT. Participants in each arm will be followed-up at three and 6 months through WeChat (a social media app like Facebook messenger). Confirmation of syphilis self-test use will be determined by requiring participants to submit a photo of the used test kit to study staff via secure data messaging. Both self-testing and facility-based testing will be ascertained by sending a secure photographic image of the completed kit through an existing digital platform. The primary outcome is the proportion of participants who tested for syphilis in the past 3 months.

DISCUSSION

Findings from this study will provide much needed insight on the impact of syphilis self-testing on promoting routine syphilis screening among MSM. The findings will also contribute to our understanding of the safety, effectiveness and acceptability of syphilis self-testing. These findings will have important implications for self-testing policy, both in China and internationally.

Verification of HIV Self-Testing Use and Results: A Global Systematic Review

HIV self-testing (HIVST) allows individuals to interpret and report their own test results, thus decentralizing testing. Yet, this decentralization can make it difficult to verify self-testing results, which is important for linkage to care and surveillance. The aim of this systematic review is to summarize methods for verifying HIVST use and results. We followed guidance from the Cochrane Handbook 5.1 on systematic reviews. We searched four journal databases (PubMed, Embase, Scopus, and Cochrane Library), one clinical trials database (ClinicalTrials.gov), two conference abstract databases (International AIDS Society and Conference on Retroviruses and Opportunistic Infections) and one gray literature database (OpenGrey). We included studies that verified opening of kits or test results. Two researchers independently screened articles and extracted data regarding HIVST location, method of verification, who performed verification, proportion of results verified, and primary or secondary kit distribution. The search yielded 3853 unique citations, of which 40 contained information on HIVST verification and were included. Among these 40 studies, 13 were in high-income countries, 16 were in middle-income countries, and 11 were in low-income countries. Seventeen studies included key populations and two focused on youth. Three methods verified results: supervision by a health provider, returning used test kits, and electronic transmission of photographs. One method verified opening of kits using Bluetooth sensors. Although HIVST has increased worldwide, strategies to verify self-testing results remain limited. These findings suggest a need for additional innovative strategies for verifying HIVST use and results and linkage of self-testing results to surveillance and care systems.

Surveying testing preferences in Black, Latin American, and other minorities for the co-design of digital vending machines for HIV self-testing

The use of digital vending machines (VMs) to delivery HIV self-testing (HIVST) could expand HIV testing in priority populations. We surveyed primarily Black African (BA) participants and other minority ethnicities, to identify acceptability, preferences, and concerns of using VMs for HIVST dispensing. A structured survey was developed with Black African and Caribbean, Latin American and other Minorities (BLAM) communities, and distributed between September 2018 and January 2019. Participants were recruited using mobile tablet surveys distributed by outreach volunteers, and online through BLAM communities’ websites, workshops, and language-specific messages on social media. Descriptive analyses were undertaken stratified by ethnic groups. One hundred and twenty-eight (67.0%) participants identified as BAs, 31 (16.2%) Black Caribbeans (BCs), 22 (11.5%) Latin Americans (LAs), and 10 (5.2%) other non-white ethnicities (ONWEs). Rates of willingness to use the HIVST were high in all groups except BCs (BAs 77.9%, BCs 53.6%, LAs 81.8%, ONWEs 80.0%). Most participants favoured healthcare-associated venues for VM placement, but there were differences in community venues favoured by different ethnic groups and concerns reported. HIVST is acceptable in many BLAM communities and increases understanding of the concerns and how to address them in the design of VMs for HIVST, to expand HIV testing in these priority communities.

Anticipated HIV stigma among HIV negative men who have sex with men in China: a cross-sectional study

BACKGROUND

Anticipated HIV stigma, i.e., the expectation of adverse experiences from one's seroconversion, is associated with both negative psychological and behavioral outcomes. We know little about anticipated HIV stigma's relationship with emerging technologies, such as HIV self-testing (HIVST) and online sex-seeking platforms, that have become popular among populations that are disproportionately affected by HIV/AIDS. This study examined correlates of anticipated HIV stigma among Chinese men who have sex with men (MSM).

METHODS

In July 2016, MSM, who were ≥ 16 years old and self-reported as HIV negative or unknown, were recruited from a gay mobile phone application in China. Information regarding socio-demographics, sexual behaviors, sexual health service utilization, and anticipated HIV stigma were collected. Anticipated HIV stigma (i.e., negative attitude toward future stigmatization of HIV seroconversion by others) was measured as the mean score from a 7-item Likert-scale ranging from 1 (low) to 4 (high). Generalized linear models were conducted to examine the factors associated with the anticipated HIV stigma scores.

RESULTS

Overall, 2006 men completed the survey. Most men completed high school (1308/2006, 65.2%) and had an annual personal income of ≤9200 USD (1431/2006, 71.3%). The mean anticipated HIV stigma score for the participants was 2.98 ± 0.64. Using social media to seek sexual partners was associated with higher anticipated HIV stigma (Adjusted β = 0.11, 95% confidence interval (CI): 0.05 to 0.17, p = 0.001). HIV self-testing (Adjusted β = - 0.07, 95%CI: - 0.13 to - 0.01, p = 0.02) and having disclosed one's sexual orientation to a healthcare provider (Adjusted β = - 0.16, 95%CI: - 0.22 to - 0.96, p < 0.001) were associated with lower anticipated HIV stigma.

CONCLUSION

Our data suggested that anticipated HIV stigma is still common among Chinese MSM not living with HIV. Tailored anti-HIV stigma campaigns on social media are especially needed, and the promotion of HIVST may be a promising approach.

Expanding syphilis testing: a scoping review of syphilis testing interventions among key populations

INTRODUCTION

Syphilis is an important sexually transmitted infection (STI). Despite inexpensive and effective treatment, few key populations receive syphilis testing. Innovative strategies are needed to increase syphilis testing among key populations. Areas covered: This scoping review focused on strategies to increase syphilis testing in key populations (men who have sex with men (MSM), sex workers, people who use drugs, transgender people, and incarcerated individuals). Expert commentary: We identified many promising syphilis testing strategies, particularly among MSM. These innovations are separated into diagnostic, clinic-based, and non-clinic based strategies. In terms of diagnostics, self-testing, dried blood spots, and point-of-care testing can decentralize syphilis testing. Effective syphilis self-testing pilots suggest the need for further attention and research. In terms of clinic-based strategies, modifying default clinical procedures can nudge physicians to more frequently recommend syphilis testing. In terms of non-clinic based strategies, venue-based screening (e.g. in correctional facilities, drug rehabilitation centres) and mobile testing units have been successfully implemented in a variety of settings. Integration of syphilis with HIV testing may facilitate implementation in settings where individuals have increased sexual risk. There is a strong need for further syphilis testing research and programs.
