Expansion of HIV testing in Eswatini: stakeholder perspectives on reaching the first 90

Achieving the United Nations’ 90-90-90 goals has proven challenging in most settings and the ambitious 95-95-95 goals seem even more elusive. However, in Eswatini – a lower-middle-income country in sub-Saharan Africa with the highest HIV prevalence in the world – an estimated 92% of people living with HIV know their status. We conducted 26 in-depth interviews with stakeholders from policy, implementation, donor, local advocacy and academic sectors to elicit the facilitators and inhibitors to HIV testing uptake in Eswatini. Background data and related reports and policy documents (n = 57) were also reviewed. Essential facilitators included good governance via institutional and national budgetary commitments, which often led to swift adoption of globally recommended programs and standards. The integration of HIV testing into all points of care fostered a sense that testing was part of routine care, which reduced stigma. Challenges, however, centred on social norms that disadvantage certain groups with high ongoing HIV risk (such as key populations, adolescent girls and young women), a heavy reliance on external donor funding, and stigma that had subsided but nevertheless persisted. Amid concerns about whether the 90-90-90 targets could be achieved by 2020, the experience of Eswatini provides tangible insights into factors that have successfully influenced HIV testing uptake and may thus prove informative for other countries.

Exploratory Analysis of HIV Status Knowledge and Associated Factors Using Data from Electronic Medical Records.

Despite recommendations for the routine HIV testing of all sexually active individuals, a significant percentage of HIV-positive adults are unaware of their HIV status. Therefore, a number of strategies have been implemented to expand HIV testing, which in turn makes it necessary to develop tools for identifying patients with unknown HIV status. This study presents the results of an external validation of an electronic phenotyping algorithm for identifying HIV status and its application on a retrospective cohort in order to explore temporal trends of HIV knowledge status and associated factors.

HIV testing uptake and yield among sexual partners of HIV-positive men who have sex with men in Zhejiang Province, China, 2014-2016: A cross-sectional pilot study of a choice-based partner tracing and testing package.

Measures to effectively expand tracing and testing to identify undiagnosed HIV infections are significant for the control of HIV/AIDS epidemic among men who have sex with men (MSM). We piloted a choice-based tracing and testing package aimed at improving partner tracing, uptake, and yield of HIV testing for sexual partners of newly diagnosed HIV-positive MSM. This package was piloted in the cities of Hangzhou and Ningbo, Zhejiang province, China from June 2014 to June 2016. The package adopted four modes: couples' HIV counseling and testing (CHCT), information assisted partner notification (IAPN), assisted HIV self-testing (HIVST) and patient referral. Data regarding sociodemographic factors and sexual behaviors between HIV-positive MSM and their sexual partners, as well as tracing and testing outcomes of each mode, were collected. Among 2,495 newly diagnosed HIV-positive MSM, 446(18%) were enrolled as index cases (ICs) through two rounds of contact tracing. The ICs disclosed a total of 4,716 sexual partners, of whom 548 (12%) were reachable. The pilot study resulted in a testing uptake of 87% (478/548), and a yield of 16% (74/478) among sexual partners. The generalized linear mixed model showed that the odds of a reachable sexual partner enrolled via IAPN taking an HIV test were 290% greater than that of a partner traced via CHCT (95% CI: 1.6, 9.3). A choice-based tracing and testing package can feasibly expand HIV testing uptake and case finding among sexual partners of HIV-positive MSM. IAPN may be an acceptable option to reach sexual partners for whom limited contact information is available.

Integrating and Interpreting Findings from the Latest Treatment as Prevention Trials.

In 2018-2019, studies were published assessing the effectiveness of reducing HIV incidence by expanding HIV testing, linkage to HIV treatment, and assistance to persons living with HIV to adhere to their medications (the "90-90-90" strategy). These tests of "treatment as prevention" (TasP) had complex results. The TasP/ANRS 12249 study in South Africa, the SEARCH study in Kenya and Uganda, and one comparison (arms A to C) of the HPTN 071 (PopART) study in South Africa and Zambia did not demonstrate a community impact on HIV incidence. In contrast, the Botswana Ya Tsie study and the second comparison (arms B to C) of PopART indicated significant ≈ 30% reductions in HIV incidence in the intervention communities where TasP was expanded. We discuss the results of these trials and outline future research and challenges. These include the efficient expansion of widespread HIV testing, better linkage to care, and viral suppression among all persons living with HIV. A top implementation science priority for the next decade is to determine what strategies to use in specific local contexts.

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.

Intersectional Stigma and Multi-Level Barriers to HIV Testing Among Foreign-Born Black Men From the Caribbean.

Testing is the entry point into the HIV care continuum that includes linkage to and retention in prevention services, and adherence to prevention strategies, including repeat HIV testing. Despite US policy approaches to expand HIV testing to diverse clinical care and community settings, disparities in HIV testing among Black populations persist. Foreign-born (FB) Black persons from the Caribbean have higher annual rates of HIV diagnosis and a higher percentage of late-stage HIV diagnosis, compared with US-born Black persons; and most HIV infections among FB Blacks are among men. In this article, we provide an overview of HIV testing barriers among FB Black men who engage in HIV risk-taking behaviors (e.g., condomless sex with male and/or female partners of unknown HIV serostatus). Barriers to HIV testing for both FB and US-born Black men, include HIV stigma (anticipated, perceived, internalized), low perceived HIV risk, medical or government mistrust, and perceived low access to testing resources. We examine beliefs about masculinity and gender roles that may perpetuate heteronormative stereotypes associated with perceptions of low HIV risk and barriers to HIV testing. We also discuss the impact of recent immigration policies on accessing HIV testing and treatment services and how intersectional stigmas and structural forms of oppression, such as racism, prejudice against select immigrant groups, and homophobia that may further amplify barriers to HIV testing among FB Black men. Finally, we review comprehensive prevention approaches, and suggest innovative approaches, that may improve the uptake of HIV testing among FB Black men.

HIV self-testing among men who have sex with men in China: a qualitative implementation research study

BackgroundHIV self-testing (HIVST) may expand HIV testing, but there have been few pilot programmes among men who have sex with men (MSM). This purpose of this study was to evaluate HIVST implementation among MSM in China using qualitative methods. MethodsWe undertook semistructured interviews among MSM and those organising HIVST programmes for MSM. Purposive sampling method was used to ensure men with different HIV serostatuses, ages and HIVST frequencies were included. Men were recruited from MSM community-based organisations and a local HIV clinic. An implementation science framework was used to interpret the findings. Two individuals used a standard code-based methodology to identify themes. ResultsForty-two MSM and six stakeholders were interviewed. Our data showed many MSM and stakeholders preferred HIVST to facility-based testing. Most men reported that HIVST empowered MSM and informed sexual decision making. Many men noted that decreasing the HIVST price may increase demand. Some men noted that HIVST could be scaled up through social media and by modifying bulky packaging. Minimal adverse events were reported. ConclusionsHIVST may expand HIV testing and promote empowerment of MSM. Minimal adverse outcomes were noted, but further implementation research is needed.

What happens after HIV self-testing? Results from a longitudinal cohort of Chinese men who have sex with men

BackgroundHIV self-testing (HIVST) is a promising approach to expand HIV testing. HIVST is a process in which a person performs an HIV test and interprets the result. Negative HIVST results may encourage men who have sex with men (MSM) to use HIV prevention services. The objective of this study was to examine behaviors (e.g., facility-based HIV testing, condom use) after a negative HIVST test result among Chinese MSM.MethodsWe collected data from MSM in eight Chinese cities over a 12-month period. This is a secondary analysis of longitudinal cohort data collected as part of an intervention trial to increase HIV testing. Men completed a survey that described sociodemographic information, sexual behaviors, HIV self-testing, and facility-based HIV testing. Men who completed at least one follow-up survey were included in this analysis. Generalized linear mixed models were used to evaluate whether HIVST increased subsequent facility-based HIV testing and consistent condom use.ResultsWe included 1219 men. Most men (78.7%) were under 30 years old and had never been married (87.0%). 755 (61.9%) men tested for HIV and 593 (49.3%) men self-tested during the study period. At baseline, among men who had never been tested for HIV, 44.9% (314/699) initiated HIVST during the study period. HIVST was associated with subsequent facility-based testing (aOR of 1.87, 95% CI: 1.47–2.37). HIVST was also associated with subsequent consistent condom use (aOR = 1.53, 95% CI: 1.13–2.06).ConclusionHIVST was associated with subsequent facility-based HIV testing and consistent condom use. HIVST may enhance uptake of related HIV prevention services at facilities, suggesting the need for more implementation research.

Suboptimal Recent and Regular HIV Testing Among Black Men Who Have Sex With Men in the United States: Implications From a Meta-Analysis.

The continuum of HIV care among black men who have sex with men (BMSM) continues to be the least favorable in the United States. BMSM are disproportionally HIV-infected-but-unaware, despite expanded HIV testing efforts among this subgroup. We meta-analytically analyzed various HIV testing patterns [lifetime, after 24 months, after 12 months, after 6 months, and frequent (every 3-6 months) testing] among BMSM using the PRISMA guideline. PubMed, MEDLINE, Web of Science, and PsycINFO were searched for relevant articles, reports, conference proceedings, and dissertations published between January 1, 1996, and April 25, 2018. Two independent investigators reviewed and abstracted data into a standardized form. We used the DerSimonian-Laird random-effect model to pool the HIV testing prevalence and I-square statistics to measure heterogeneity. Funnel plots and Egger tests were used to assess for publication bias. We also performed subgroup and meta-regression analyses to explore aggregate-level characteristics that explain the heterogeneity across studies. Our meta-analysis includes a total of 42,074 BMSM pooled from 67 studies. Lifetime HIV testing prevalence was high, 88.2% [95% confidence interval (CI): 86.2% to 90.1%], but recent (after 6 months = 63.4%; 95% CI: 59.3% to 67.4%) and frequent (42.2%, 95% CI: 34.1% to 50.3%) HIV testing prevalence was low. Meta-regression suggests that younger age (borderline significant), lower annual income, and homelessness were correlated with lower lifetime/recent HIV testing prevalence; while ever having condomless insertive/receptive sex, alcohol consumption, and illicit drug use were associated with higher lifetime/recent HIV testing prevalence. Recent and frequent HIV testing remains suboptimal among BMSM. Future testing programs should prioritize strategies to enhance self-initiated, regular HIV testing among BMSM.

Incentives Versus Defaults: Cost-Effectiveness of Behavioral Approaches for HIV Screening.

Many HIV positive individuals are still undiagnosed, which has led health systems to try many approaches to expand HIV testing. In a randomized controlled trial, we found that behavioral economics interventions (opt-out testing and financial incentives) each improved HIV testing rates and these approaches are being implemented by several hospital systems. However, it is unclear if these strategies are cost-effective. We quantified the cost-effectiveness of different behavioral approaches to HIV screening-opt-out testing, financial incentives, and their combination-in terms of cost per new HIV diagnosis and infections averted. We estimated the incremental number of new HIV diagnoses and program costs using a mathematical screening model, and infections averted using and HIV transmission model. We used a 1-year time horizon and a hospital perspective. Switching from opt-into opt-out results in 39 additional diagnoses (56% increase) after 1-year at a cost of $3807 per new diagnosis. Switching from no incentive to a $1, $5, or $10 incentive adds 14, 13, and 28 new diagnoses (20, 19, and 41% increases) at a cost of $11,050, $17,984, and $15,298 per new diagnosis, respectively. Layering on financial incentives to opt-out testing enhances program effectiveness, though at a greater marginal cost per diagnosis. We found a similar pattern for infections averted. This is one of the first cost-effectiveness analyses of behavioral economics interventions in public health. Changing the choice architecture from opt-into opt-out and giving financial incentives for testing are both cost-effective in terms of detecting HIV and reducing transmission. For hospitals interested in increasing HIV screening rates, changing the choice architecture is an efficient strategy and more efficient than incentives.

HIV Epidemiology and Prevention in Southwestern China: Trends from 1996-2017.

The aim of this review is to describe long-term HIV epidemiology and prevention trends in Guangxi, a provincial-level region located along a major drug trafficking corridor in southwestern China. Between 1996 and 2006, HIV transmission in Guangxi was primarily fueled by Injection Drug Use (IDU). Since 2006, heterosexual sex has become the dominant mode of HIV transmission, followed by drug injection. Moreover, older, heterosexual adults appear to be at increased risk for HIV. The vast majority of new HIV cases are attributed to local HIV subtypes already circulating within Guangxi (93%), though imported subtypes are associated with younger age groups. Since 2011, HIV incidence in Guangxi has stabilized, due in part to HIV prevention efforts that include expanded HIV testing, antiretroviral treatment, and other intervention measures. Between 1996 and 2017, Guangxi, China experienced dramatic changes in the primary HIV transmission mode and at-risk age group. Due in part to local and National AIDS control and prevention campaigns, HIV incidence trends in Guangxi no longer appear to be increasing.

Ghana's HIV epidemic and PEPFAR's contribution towards epidemic control.

The aim of this review was to summarize the data on HIV/AIDS epidemiology and affected populations in Ghana and to describe the United States President's Emergency Plan for Emergency Relief's (PEPFAR) response to the epidemic. We conducted a literature review focusing on PEPFAR's contribution to the HIV response in Ghana. Additionally, we summarized the epidemiology of HIV. We searched both peer-reviewed and grey literature. Ghana. Overall, HIV prevalence in Ghana is 1.6% with regional variation. Key populations (KPs) are disproportionately affected by HIV in the country. FSW and their clients, and MSM, account for 28% of all new infections. PEPFAR provides technical assistance (TA) to Ghana to maximize the quality, coverage and impact of the national HIV/AIDS response. To ensure adequate supply of antiretrovirals (ARVs), in 2016-2017, PEPFAR invested $23.7 million as a onetime supplemental funding to support Ghana's ARV treatment program. In addition, the National AIDS Control Programme in collaboration with PEPFAR is implementing a scale up of viral load testing. PEPFAR is also implementing a comprehensive package of prevention services in five regions to help reach MSM and FSW and to expand HIV testing services for KPs. Ghana is making changes at both policy and program level in the fight against HIV/AIDS and is working towards achieving the UNAIDS' 90-90-90 targets. PEPFAR is providing TA to ensure these goals can be achieved. This manuscript has been supported by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) through the Centers for Disease Control and Prevention (CDC).

Underutilization of HIV Testing Among Men with Incarceration Histories.

Annual HIV testing is recommended for individuals at high risk of infection, specifically incarcerated populations. Incarcerated men carry a higher lifetime risk of acquiring HIV than the general population, yet little is known about their HIV testing behaviors. We collected Audio Computer Assisted Self Interview data for 819 men entering a state prison in North Carolina. We assessed correlates of previous HIV testing, including stigmatizing attitudes and beliefs, and explored two outcomes: (1) ever HIV tested before current incarceration, and (2) recency of last HIV test. Eighty percent had been HIV tested before; of those, 36% reported testing within the last year. Being African American, having education beyond high school, prior incarceration, and higher HIV knowledge increased odds of ever having tested. Results of this study highlight the need to expand HIV testing and education specific to incarcerated populations. Additionally, efforts should be made to monitor and encourage repeat screening.

Routine HIV testing program in the University Infectious Diseases Centre in Lithuania: a four-year analysis

BackgroundHIV transmission remains a major concern in Eastern Europe, and too many people are diagnosed late. Expanded testing strategies and early and appropriate access to care are required. Infectious disease departments might be targets for expanded HIV testing owing to the intense passage of key patient populations that carry indicators of HIV disease. Our objective was to evaluate the feasibility and clinical effectiveness of a fully integrated, opt-out routine, rapid HIV testing program.MethodsA retrospective four-year study of a screening program was conducted from 2010 through 2014. The program was divided into two periods: from 2010 to 2012 (pilot study) and from 2013 to 2014. The pilot study consisted of routine HIV testing of patients aged 18–55 that were hospitalized in one department. In the second period, all inpatients aged 18–65 were eligible. Targeted testing was conducted in the other inpatient department during the pilot study and the outpatient department during both periods.ResultsDuring the pilot study, 2203 patients were hospitalized, 1314 (59.6%) were eligible, 954 (72.6%) were tested, and 3 (0.31%) were newly diagnosed HIV-positive. In the second period, 4911 patients were hospitalized, 3727 (75.9%) were eligible, 3303 (88.6%) were tested, and 7 (0.21%) were HIV-positive. In total, 2800 targeted tests were performed, and 4 (0.14%) patients tested positive with newly discovered HIV. All 14 newly diagnosed patients were provided with care. Comparing cumulative groups of routine and targeted testing, the HIV prevalence was 0.23% vs. 0.14% (p = 0.40) and was above the reported cost-effectiveness threshold of 0.1% (p = 0.012). A lower proportion of advanced disease and a higher proportion of heterosexually transmitted infection were found in the routine testing group.ConclusionRoutine HIV testing in admissions of infectious diseases is acceptable, feasible, sustainable and clinically effective. Compared to targeted testing, routine testing helped to discover more patients in earlier stages and those with heterosexually transmitted HIV infection.

Impact of the 90-90-90 goal and pre-exposure prophylaxis on HIV transmission and elimination in men who have sex with men in China: A mathematical modeling study

Objective: To establish a dynamic compartmental model to predict the impact of HIV testing and treatment and pre-exposure prophylaxis (PrEP) on the annual incidence of HIV infection in men who have sex with men (MSM) in China from 2018 to 2037. Methods: A dynamic compartmental model was developed to describe the HIV epidemic in MSM in China. The model was parameterized using data from the literature available. We used MATLAB 7.0 software for data simulation and graphics rendering. We analyzed HIV transmission among MSM and estimated the impact of expanded HIV testing and treatment and PrEP on HIV elimination in MSM. Results: Under the current policy, the number of new HIV infections would reach 770 000, the infection rate would reach 11.1% and the incidence rate would reach 0.72/100 person years in MSM in the next 20 years. Under the 90%-90%-90% goal, 440 000 new infections (57.7%) would be reduced, the HIV infection rate would decline to 5.7% and the incidence rate would decline to 0.24/100 person years in the next 20 years, but it is still unlikely to achieve the goal of HIV elimination. With 100% PrEP compliance, the required PrEP coverage rates for achieving HIV elimination in the next 10, 15 and 20 years would be 65%, 32% and 19%, respectively. Conclusion: It is necessary to strengthen the comprehensive intervention in MSM, continue to expand HIV testing and treatment, and improve PrEP adherence and coverage to further control and eliminate the epidemic of HIV/AIDS in MSM.

Gender Differences in HIV Testing, Diagnosis, and Linkage to Care in Healthcare Settings: Identifying African American Women with HIV in Chicago

Women account for 25% of all people living with HIV and 19% of new diagnoses in the United States. African American (AA) women are disproportionately affected. Yet, differences in the care continuum entry are not well understood between patient populations and healthcare sites. We aim to examine gender differences in diagnosis and linkage to care (LTC) in the Expanded HIV Testing and Linkage to Care (X-TLC) program within healthcare settings. Data were collected from 14 sites on the South and West sides of Chicago. Multivariate logistic regression analysis was used to determine the differences in HIV diagnoses and LTC by gender and HIV status. From 2011 to 2016, X-TLC performed 281,017 HIV tests; 63.7% of those tested were women. Overall HIV seroprevalence was 0.57%, and nearly one third (29.4%) of HIV-positive patients identified were cisgender women. Of newly diagnosed HIV-positive women, 89% were AA. 58.5% of new diagnoses in women were made at acute care hospitals, with the remainder at community health centers. Women who were newly diagnosed had a higher baseline CD4 count at diagnosis compared with men. Overall, women had lower odds of LTC compared with men (adjusted odds ratio = 0.58, 95% confidence interval 0.44-0.78) when controlling for patient demographics and newly versus previously diagnosed HIV status. Thus, interventions that focus on optimizing entry into the care continuum for AA women need to be explored.
