Willingness to distribute free rapid home HIV test kits and to test with social or sexual network associates among men who have sex with men in the United States

Digital Strategies Supporting Social Network Approaches to HIV Testing: A Scoping Review

PURPOSE OF REVIEW

This review captured how digital strategies support social network approaches to promote HIV testing.

RECENT FINDING

Overall, 29 studies were identified by searching PubMed and Embase for studies published up to June 2023. Existing studies revealed three types of digital strategies (social media (n = 28), online information channels (n = 4), and multifunctional digital platforms (n = 4)) split into four major modes of digital strategy-supported social-network-based HIV testing promotion: 1) Online outreach and recruiting, 2) gathering and identifying key populations for HIV testing, 3) communicating and disseminating online HIV testing health interventions, and 4) assisting and facilitating HIV testing uptake and distribution. Social network approaches supported by digital strategies yielded advantages in HIV testing education and distribution, which increases HIV testing coverage among key populations. Studies are needed on how to facilitate the use of digital strategies for social network-based HIV testing, as well as how to integrate them with existing HIV testing approaches.

Salient beliefs related to secondary distribution of COVID-19 self-test kits within social networks

Background

Widespread access to testing is critical to public health efforts to control the COVID-19 pandemic. Secondary distribution of COVID-19 self-test kits, where an individual distributes test kits to others in their social networks, is a potential strategy to improve access to testing. In this qualitative study, we identified salient beliefs about distributing and accepting COVID-19 self-test kits within one's social network, as well as ordering COVID-19 self-test kits from the government.

Methods

We recruited 61 participants from a randomized controlled trial (NCT04797858) in Philadelphia, Pennsylvania to elicit beliefs about (1) distributing COVID-19 self-test kits within one's social network, (2) receiving test kits from social contacts, and (3) ordering self-test kits from the government. Using validated, open-ended question stems, we identified the most common set of beliefs underlying attitudes, perceived norms (or social referents), and perceived behavioral control (or self-efficacy) toward each of these behaviors.

Results

Twenty-seven out of 30 (90%) of participants who received self-test kits reported distributing the kits to social contacts. These participants described altruistic beliefs about giving others access to testing, and felt approval from family members, friends, and others in their social networks. When receiving test kits from social network contacts, participants described advantages of test kit convenience, but some voiced concern about test kit tampering and confusing instructions. Participants also described perceived logistic barriers to distributing and receiving self-test kits, such as delivering or transporting test kits, or finding time to meet. Participants who ordered test kits from the government also described increased convenience of test access, but described different logistic barriers such as delays in test kit delivery, or not receiving test kits at all.

Conclusion

In comparison with government-ordered test kits, the secondary distribution of COVID-19 self-test kits raised unique concerns about test kit quality and instructions, as well as distinctive logistic barriers related to distributing self-test kits to network contacts, which were not raised for test kits ordered from the government. This study demonstrates that beliefs may vary depending on the type of testing behavior, and behavioral interventions may benefit from developing messages tailored to specific testing strategies.

Testing Together Behaviors in Secondary Distribution of HIV/Syphilis Self-testing Program Among Men Who have Sex with Men in China

HIV self-testing (HIVST) is recommended as a promising way to increase HIV testing uptake among MSM. MSM sometimes used HIVST kits together with their sexual partners or friends. However, limited data was reported on MSM's testing together behaviors with sexual partners and non-sexual contacts. Data were collected among MSM in China from June 2018 to June 2019. Eligible participants (referred to as "index participants") finished a baseline survey and applied for HIVST kits. They were encouraged to distribute the kits to other people (referred to as "alters"). Index participants finished a 3-month follow-up survey on the distribution and usage of the kits. Alters finished an online survey on the usage of HIVST kits after they returned the photographed testing results. Results were reported based on index participants and alters, respectively. Based on follow-up data, 138 index participants successfully motivated others for HIVST, most of them (77.5%) tested together with at least one alter. Around half of alters (52.3%) reported testing together with index participants. Index participants distributed more HIVST kits to friends than sexual partners. MSM who had ever tested for HIV were more likely to test together. Our study demonstrated that the testing together behaviors during HIVST distribution among sexual partners and social network contacts were common. The social network-based approach is essential in promoting testing together and HIV status disclosure among MSM.

Highlighting and addressing barriers to widespread adaptation of HIV self-testing in the United States

INTRODUCTION

HIV self-testing (HIVST), whereby an individual performs and interprets their own rapid screening test at home, is another tool to increase the proportion of at-risk individuals who know their status. Globally, HIVST has rapidly been adopted through global partnerships to ensure equitable access to tests in low- and middle-income countries (LMIC).

AREA COVERED

This review discusses the regulatory burdens of HIV self-testing within the United States while examining the use of HIV self-tests on a global scale. While the United States only has one approved HIV self-test, numerous tests have been prequalified by the WHO.

EXPERT OPINION

Despite the US Food and Drug Administration (FDA) clearance of the first and only self-test in 2012, there have been no other tests that have undergone FDA consideration due to regulatory barriers. This, in turn, has stifled market competition. Despite existing evidence that such programs are an innovative approach to testing hesitant or hard-to-reach populations, high individual test cost and bulky packaging make large-scale, mail-out, and HIV self-testing programs expensive. COVID-19 pandemic has accelerated the public demand for self-testing - HIV self-test programs should capitalize on this to increase the proportion of at-risk people who know their status and are linked to care to contribute to ending the HIV epidemic.

HIV Testing Strategies, Types of Tests, and Uptake by Men Who have Sex with Men and Transgender Women: A Systematic Review and Meta-analysis

This systematic review and meta-analysis investigated the effectiveness of strategies and types of tests on HIV testing uptake by men who have sex with men (MSM) and transgender women (TGW), and in reaching PLWH. Articles published up to July 2020 were identified from major electronic databases and grey literature. Data were extracted and assessed for risk of bias. Estimates were pooled using random-effect meta-analysis while heterogeneity was evaluated by Cochran's Q test and I². This study is registered with PROSPERO (CRD42020192740). Of 6820 titles, 263 studies (n = 67,288 participants) were included. The testing strategies reported in most studies were community- (71.2%) and facility-based (28.8%). Highest uptake, with facility-based testing, occurred and reached more PLWH while with standard laboratory tests, it occurred with the highest HIV prevalence among MSM. However, urine test showed a highest rate of new HIV infection. Multiple test combinations had the highest uptake and reached more PLWH among TGW. Various testing strategies, considering barriers and regional differences, and different test types, need be considered, to increase uptake among MSM and TGW.

Distribution of HIV Self-tests by Men Who have Sex with Men (MSM) to Social Network Associates

Internet-recruited gay, bisexual, and other men who have sex with men (MSM) were offered HIV self-tests (HIVSTs) after completing baseline, 3-, 6-, and 9-month follow-up surveys. The surveys asked about the use and distribution of these HIVSTs. Among 995 who reported on their distribution of HIVSTs, 667 (67.0%) distributed HIVSTs to their social network associates (SNAs), which resulted in 34 newly identified HIV infections among 2301 SNAs (1.5%). The main reasons participants reported not distributing HIVSTs included: wanting to use the HIVSTs themselves (74.9%); thinking that their SNAs would get angry or upset if offered HIVSTs (12.5%); or not knowing that they could give the HIVSTs away (11.3%). Self-testing programs can provide multiple HIVSTs and encourage the distribution of HIVST by MSM to their SNAs to increase awareness of HIV status among persons disproportionately affected by HIV.

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

OBJECTIVE

To determine the feasibility, acceptability, and implementation of a HIV self-test (HIVST) program through PrEP clients' social and sexual networks.

BACKGROUND

HIV testing is critical for treatment and prevention engagement. HIVST kits can overcome barriers to testing. A negative result is an opportunity to provide PrEP information. We describe implementation factors associated with engaging current Mobile PrEP (MP) clients to distribute HIVST kits and PrEP information through their networks.

SETTING

Community venues in Miami-Dade County, Florida.

METHODS

A baseline survey collected network information and explored distribution plans for offering HIVST kits. A follow-up survey evaluated use and distribution. A logic model describes the process of implementation and evaluation. Up to 4 Ora-Quick HIV ST kits were offered to 81 MP clients. A brief training included resources for posttest engagement.

RESULTS

Forty-four percent of the kits were reported as distributed. Of 81 MP clients offered kits, 50 (62%) accepted. In a follow-up survey, 77% of MP clients distributed at least 1 kit. Fifty-six (86%) social network members were Latino, and 9 (14%) were Black. Three of 4 MP clients engaged in PrEP discussions (77%) with SN members. Reported reasons for HIVST kit use included convenience, confidentiality, privacy concerns, and discomfort with going to a testing site. MP clients reported that kit distribution was affected by the COVID-19 pandemic.

CONCLUSION

HIV ST kits allowed PrEP users to engage others in their social and sexual networks for HIV testing and information regarding PrEP. Work to scale-up this intervention is underway.

Effect of HIV Self-Testing on PrEP Adherence Among Gender-Diverse Sex Workers in Uganda: A Randomized Trial

BACKGROUND

HIV self-testing (HIVST) and pre-exposure prophylaxis (PrEP) are complementary tools that could empower sex workers to control their HIV protection, but few studies have jointly evaluated PrEP and HIVST in any setting.

METHODS

The Empower Study was an open-label randomized trial in Uganda. Sex workers were offered F/tenofovir disoproxil fumarate and randomized 1:1 to monthly HIVST and quarterly in-clinic testing (intervention) or quarterly in-clinic HIV testing alone (standard of care) and followed up for 12 months. PrEP adherence was measured using electronic adherence monitoring and tenofovir diphosphate (TFV-DP) levels in dried blood spots. Adherence outcomes and sexual behaviors were compared by arm using generalized estimating equation models.

RESULTS

We enrolled 110 sex workers: 84 cisgender women, 14 transgender women, 10 men who have sex with men, and 2 transgender men. The median age was 23 years. The 12-month retention was 75%. Nearly all (99.4%) used ≥1 HIVST kit. The proportion with TFV-DP levels ≥700 fmol/punch in the HIVST and standard of care arms at the 3-, 6-, 9-, and 12-month visits was 2.4%, 2.3%, 0%, and 0% and 7.9%, 0%, 0%, and 0%, respectively, with no differences by randomization arm (P > 0.2). Self-reported condomless sex acts with paying partners was similar by arm [adjusted incidence rate ratio 0.70; 95% confidence interval (CI): 0.42 to 1.17; P = 0.18]. One seroconversion occurred (HIV incidence, 0.9/100 person-years); TFV-DP was not detected at any visit.

CONCLUSIONS

A gender-diverse sample of sex workers in Uganda used HIVST but not daily oral PrEP for HIV protection. Alternate approaches to promote PrEP use, including long-acting formulations, should be considered in this population.

Outcomes of a community-led online-based HIV self-testing demonstration among cisgender men who have sex with men and transgender women in the Philippines during the COVID-19 pandemic: a retrospective cohort study

INTRODUCTION

The Philippines, which has the fastest rising HIV epidemic globally, has limited options for HIV testing and its uptake remains low among cisgender men who have sex with men (cis-MSM) and transgender women (TGW), especially amid the COVID-19 pandemic. As HIV self-testing (HIVST) and technology-based approaches could synergize to expand uptake of HIV testing, we aimed to evaluate the outcomes of a community-led online-based HIVST demonstration and to explore factors associated with HIVST-related behaviours and outcomes.

METHODS

We did a secondary data analysis among cis-MSM and TGW who participated in the HIVST demonstration, who were recruited online and tested out-of-facility, in Western Visayas, Philippines, from March to November 2020. We reviewed data on demographics, sexuality-, and context-related variables. Using multivariable logistic regression, we tested for associations between the aforementioned covariates and two primary outcomes, opting for directly-assisted HIVST (DAH) and willingness to secondarily distribute kits.

RESULTS

HIVST kits were distributed to 647 individuals (590 cis-MSM, 57 TGW), 54.6% were first-time testers, 10.4% opted DAH, and 46.1% were willing to distribute to peers. Reporting rate was high (99.3%) with 7.6% reactivity rate. While linkage to prevention (100%) and care (85.7%) were high, pre-exposure prophylaxis (PrEP) (0.3%) and antiretroviral therapy (ART) (51.0%) initiation were limited. There were no reports of adverse events. Those who were employed, had recent anal intercourse, opted for DAH, not willing to secondarily distribute, and accessed HIVST during minimal to no quarantine restriction had significantly higher reactivity rates. Likelihood of opting for DAH was higher among those who had three or more partners in the past year (aOR = 2.01 [CI = 1.01-4.35]) and those who accessed during maximal quarantine restrictions (aOR = 4.25 [CI = 2.46-7.43]). Odds of willingness to share were higher among those in urban areas (aOR = 1.64 [CI = 1.15-2.36]) but lower among first-time testers (aOR = 0.45 [CI = 0.32-0.62]).

CONCLUSIONS

HIVST could effectively reach hard-to-reach populations. While there was demand in accessing online-based unassisted approaches, DAH should still be offered. Uptake of PrEP and same-day ART should be upscaled by decentralizing these services to community-based organizations. Differentiated service delivery is key to respond to preferences and values of key populations amid the dynamic geographical and sociocultural contexts they are in.

Men's comfort in distributing or receiving HIV self-test kits from close male social network members in Dar Es Salaam, Tanzania: baseline results from the STEP project

Background

A variety of strategies have been used to reach men with HIV self-testing services, including social network-based HIV self-test kits distribution. However, few studies have assessed men’s comfort to distribute to or receive HIV self-test kits from close male friends within the same social network. In this study, we assessed men’s comfort to distribute to and/or receive HIV self-test kits from close male friends and associated factors among men who socialize in networks locally referred to as “camps” in Tanzania.

Methods

Data are from the baseline survey of a cluster-randomized controlled trial conducted in June 2019 with 18 social networks or “camps” in Dar es Salaam, Tanzania. Participants were 18-year-old or older male camp members who were HIV-negative at the time of enrolment. We used the Generalized Estimating Equations (GEE) to assess factors associated with being comfortable to distribute to and/or receive HIV self-test kits from close male members within one’s social network.

Results

Of 505 participants, 67.9% (n = 342) reported being comfortable to distribute to while 68.2% (n = 344) were comfortable to receive HIV self-test kits from their close male friends. Ever having heard about HIV self-testing (Adjusted Prevalence Ratio (Adj. PR): 1.6; 95% Confidence Interval [CI]: 1.3, 1.9), willingness to self-test for HIV in front of a sexual partner (Adj. PR: 3.0; 95%CI: 1.5, 6.1) and exposure to peer-led HIV self-testing education and promotion (Adj. PR: 1.4; 95%CI: 1.2, 1.7) were significantly associated with being comfortable to distribute HIV self-test kits to close male members within one’s social network. Similar results were observed for being comfortable to receive HIV self-test kits from a close male friend within one’s social network.

Conclusions

Overall, these findings suggest that distribution of HIV self-test kits through close male friends could improve the proportion of men reached with HIV self-testing services and improve HIV testing rates in this population where uptake remains low. However, additional promotional strategies such as peer-led HIV self-testing education are needed to raise awareness and increase the proportion of men who are comfortable to receive and/or distribute HIV self-testing kits.

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.

Cost-Effectiveness of Peer-Delivered HIV Self-Tests for MSM in Uganda

Introduction: Distribution of HIV self-testing (HIVST) kits through MSM peer networks is a novel and effective strategy to increase HIV testing coverage in this high-risk population. No study has evaluated the cost or cost effectiveness of peer distribution of HIVST strategies among MSM in sub-Saharan Africa. Methods: From June to August 2018, we conducted a pilot study of secondary MSM peer HIVST kit distribution at The AIDS Support Organization at Entebbe and Masaka. We used an ingredients approach to estimate the cost of MSM peer HIVST kit distribution relative to standard-of-care (SOC) hotspot testing using programme expenditure data reported in US dollars. The provider perspective was used to estimate incremental cost-effective ratios per HIV infection averted using the difference in HIV annual transmission rates between MSM with HIV who knew their status and were not virologically suppressed and MSM with HIV who did not know their status. Results: We enrolled 297 participants of whom 150 received MSM peer HIVST kit distribution (intervention group) and 147 received TASO standard of care HIV testing (control group). Provider cost for the intervention was $2,276 compared with $1,827 for SOC during the 3-month study period. Overall, the intervention resulted in higher HIV positivity yield (4.9 vs. 1.4%) and averted more HIV infections per quarter (0.364 vs. 0.104) compared with SOC. The cost per person tested was higher for the intervention compared to SOC ($15.90 vs. $12.40). Importantly, the cost per new HIV diagnosis ($325 vs. $914) and cost per transmission averted ($6,253 vs. $ 17,567) were lower for the intervention approach relative to SOC. The incremental cost per HIV transmission averted by the self-testing program was $1,727. The incremental cost to providers per additional HIV-positive person identified by the intervention was $147.30. Conclusion: The intervention strategy was cost-effective, and identified more undiagnosed HIV infections than SOC hotspot testing at a cost-effectiveness threshold of US $2,129. Secondary distribution of HIVST kits through peers should further be evaluated with longer duration aimed at diagnosing 95% of all persons with HIV by 2030; the first UNAIDS 95-95-95 target.

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.

Facilitators and Barriers of HIV Self-Testing Among Chinese Men Who Have Sex With Men: A Qualitative Study

Supplemental Digital Content is Available in the Text.

HIV self-testing (HIVST) could increase HIV testing. However, HIVST uptake rate among Chinese men who have sex with men (MSM) is low. We conducted qualitative interviews with 23 MSM, 4 workers from community-based organizations, and 7 officials from both provincial Centers for Disease Control and Prevention and affiliated city-level Centers for Disease Control and Preventions to explore facilitators and barriers of HIVST among Chinese MSM. Eight barriers were identified, including fear of being duped by a fake test, concern for cost, fear of disclosing sexual orientation, limited access, lack of consulting services, biosafety concerns, lack of policy support, and concern for lost opportunities to link men to care. Five facilitators were identified, including convenience, confidentiality, easy operation, partner HIV testing, and peers' influence. Officials and scholars should urgently address structural barriers and provide accessible, affordable, and high-quality HIVST services that are accompanied by counseling to develop culturally appropriate HIVST guidelines.

Impact of providing free HIV self-testing kits on frequency of testing among men who have sex with men and their sexual partners in China: A randomized controlled trial

BACKGROUND

The HIV epidemic is rapidly growing among men who have sex with men (MSM) in China, yet HIV testing remains suboptimal. We aimed to determine the impact of HIV self-testing (HIVST) interventions on frequency of HIV testing among Chinese MSM and their sexual partners.

METHODS AND FINDINGS

This randomized controlled trial was conducted in 4 cities in Hunan Province, China. Sexually active and HIV-negative MSM were recruited from communities and randomly assigned (1:1) to intervention or control arms. Participants in the control arm had access to site-based HIV testing (SBHT); those in the intervention arm were provided with 2 free finger-prick-based HIVST kits at enrollment and could receive 2 to 4 kits delivered through express mail every 3 months for 1 year in addition to SBHT. They were encouraged to distribute HIVST kits to their sexual partners. The primary outcome was the number of HIV tests taken by MSM participants, and the secondary outcome was the number of HIV tests taken by their sexual partners during 12 months of follow-up. The effect size for the primary and secondary outcomes was evaluated as the standardized mean difference (SMD) in testing frequency between intervention and control arms. Between April 14, 2018, and June 30, 2018, 230 MSM were recruited. Mean age was 29 years; 77% attended college; 75% were single. The analysis population who completed at least one follow-up questionnaire included 110 (93%, 110/118) in the intervention and 106 (95%, 106/112) in the control arm. The average frequency of HIV tests per participant in the intervention arm (3.75) was higher than that in the control arm (1.80; SMD 1.26; 95% CI 0.97-1.55; P < 0.001). This difference was mainly due to the difference in HIVST between the 2 arms (intervention 2.18 versus control 0.41; SMD 1.30; 95% CI 1.01-1.59; P < 0.001), whereas the average frequency of SBHT was comparable (1.57 versus 1.40, SMD 0.14; 95% CI -0.13 to 0.40; P = 0.519). The average frequency of HIV tests among sexual partners of each participant was higher in intervention than control arm (2.65 versus 1.31; SMD 0.64; 95% CI 0.36-0.92; P < 0.001), and this difference was also due to the difference in HIVST between the 2 arms (intervention 1.41 versus control 0.36; SMD 0.75; 95% CI 0.47-1.04; P < 0.001) but not SBHT (1.24 versus 0.96; SMD 0.23; 95% CI -0.05 to 0.50; P = 0.055). Zero-inflated Poisson regression analyses showed that the likelihood of taking HIV testing among intervention participants were 2.1 times greater than that of control participants (adjusted rate ratio [RR] 2.10; 95% CI 1.75-2.53, P < 0.001), and their sexual partners were 1.55 times more likely to take HIV tests in the intervention arm compared with the control arm (1.55, 1.23-1.95, P < 0.001). During the study period, 3 participants in the intervention arm and none in the control arm tested HIV positive, and 8 sexual partners of intervention arm participants also tested positive. No other adverse events were reported. Limitations in this study included the data on number of SBHT were solely based on self-report by the participants, but self-reported number of HIVST in the intervention arm was validated; the number of partner HIV testing was indirectly reported by participants because of difficulties in accessing each of their partners.

CONCLUSIONS

In this study, we found that providing free HIVST kits significantly increased testing frequency among Chinese MSM and effectively enlarged HIV testing coverage by enhancing partner HIV testing through distribution of kits within their sexual networks.

HIV Self-Testing to Promote Serostatus Disclosure Among Men Who Have Sex With Men in China: Protocol for a Stepped Wedge Randomized Controlled Trial

BACKGROUND

Disclosure of HIV serostatus is important for the prevention of HIV infection among men who have sex with men (MSM). However, knowledge of sexual partners' HIV status among MSM in China is low. As a complement to HIV testing services, HIV self-testing (HIVST) has considerable potential to promote serostatus disclosure.

OBJECTIVE

The primary objective of our trial is to evaluate the effect of HIVST on improving serostatus disclosure to sexual partners. We hypothesize that MSM in an intervention condition will have a higher awareness of the HIV status of their sexual partners compared with MSM in the control condition. The secondary aims are to evaluate (i) changes in sexual behaviors after disclosure of HIV status by sexual partners, (ii) promotion of the frequency of HIV and syphilis testing on participants and their sexual partners, and (iii) factors that restrict the disclosure of HIV infection to sexual partners. We hypothesize that MSM in the intervention condition will exhibit safer sexual decision making and a higher rate of HIV testing uptake compared with MSM in the control condition.

METHODS

A stepped wedge randomized controlled trial will be conducted throughout China. Study recruitment of 800 MSM will be promoted through advertisements released on WeChat public accounts. Individuals who are born biologically male, aged ≥18 years, HIV negative, and who have not undergone HIV testing in the past 3 months will be recruited. Eligible men will be randomly divided (1:1:1:1) into four groups and randomized. The group cluster will initiate the intervention so that participants will be provided with 2-4 free finger prick-based HIVST kits until trial completion. The intervention period for participants in each of the four groups will be initiated at 3-month intervals. Men in both groups will be required to complete a baseline and four follow-up surveys every 3 months. The primary intervention outcome will evaluate the effect of the distribution of HIVST kits on improvement in the disclosure of sexual partners' HIV status. The secondary outcomes will be changes in sexual behaviors after disclosure of HIV status from sexual partners, the promotion of the frequency of HIVST on participants and their sexual partners, and the factors that restrict disclosure of HIV status to sexual partners.

RESULTS

Subject recruitment began in August 2018. The first round of follow-up surveys post intervention is complete, with three rounds remaining to be done. Data analysis was scheduled for April 2020 and the results will be disseminated through conferences and peer-reviewed publications.

CONCLUSIONS

Few studies have evaluated interventions to increase knowledge of sexual partners' HIV status among MSM. Our trial will provide information on the link between HIVST and HIV serostatus disclosure. The findings of this trial will facilitate the implementation of HIVST services to help control the spread of HIV among MSM in China.

Suitability and Sufficiency of Telehealth Clinician-Observed, Participant-Collected Samples for SARS-CoV-2 Testing: The iCollect Cohort Pilot Study

BACKGROUND

The severe acute respiratory coronavirus 2 (SARS-CoV-2) pandemic calls for expanded opportunities for testing, including novel testing strategies such as home-collected specimens.

OBJECTIVE

We aimed to understand whether oropharyngeal swab (OPS), saliva, and dried blood spot (DBS) specimens collected by participants at home and mailed to a laboratory were sufficient for use in diagnostic and serology tests of SARS-CoV-2.

METHODS

Eligible participants consented online and were mailed a participant-collection kit to support collection of three specimens for SARS-CoV-2 testing: saliva, OPS, and DBS. Participants performed the specimen collection procedures during a telehealth video appointment while clinical observers watched and documented the suitability of the collection. The biological sufficiency of the specimens for detection of SARS-CoV-2 by reverse transcriptase-polymerase chain reaction and serology testing was assessed by laboratorians using visual inspection and quantification of the nucleic acid contents of the samples by ribonuclease P (RNase P) measurements.

RESULTS

Of the enrolled participants,153/159 (96.2%) returned their kits, which were included in this analysis. All these participants attended their video appointments. Clinical observers assessed that of the samples collected, 147/153 (96.1%) of the saliva samples, 146/151 (96.7%) of the oropharyngeal samples, and 135/145 (93.1%) of the DBS samples were of sufficient quality for submission for laboratory testing; 100% of the OPS samples and 98% of the saliva samples had cycle threshold values for RNase P <30, indicating that the samples contained sufficient nucleic acid for RNA-PCR testing for SARS-CoV-2.

CONCLUSIONS

These pilot data indicate that most participant-collected OPS, saliva, and DBS specimens are suitable and sufficient for testing for SARS-CoV-2 RNA and serology. Clinical observers rated the collection of specimens as suitable for testing, and visual and quantitative laboratory assessment indicated that the specimens were biologically sufficient. These data support the utility of participant-collected and mailed-in specimens for SARS-CoV-2 testing.

SMARTtest: A Smartphone App to Facilitate HIV and Syphilis Self- and Partner-Testing, Interpretation of Results, and Linkage to Care

Acceptability of rapid HIV self-testing is high but potential users remain concerned about correct use, interpretation of test results, and linkage to care. This article describes user preferences for a smartphone app to mitigate these challenges and how these were integrated into the SMARTtest app to support self- and partner-testing using the INSTI Multiplex^®. Sixty men and transgender women who have sex with men self-tested for HIV and syphilis while guided by a prototype app that provided a video, pictorial step-by-step instructions, and sample test results presented textually ("positive," "negative"). Subsequently, participants provided feedback on revisions and additional app content. Participants recommended offering different user modes (self, partner, both), and retaining the video, step-by-step instructions, and textual test results. They strongly favored the ability to save and send test results to sexual partners or providers. These features were integrated into the SMARTtest app to facilitate HIV/syphilis self- and partner-testing, HIV/syphilis status awareness and disclosure, and linkage to care.

Three-year outcome of rapid HIV testing at public health centers in Seoul, Republic of Korea: a short report

Before 2014, the only test used for anonymous voluntary human immunodeficiency virus (HIV) screening at public health centers (PHCs) in the Republic of Korea was an enzyme-linked immunosorbent assay (ELISA), which takes around 3 days to obtain results. In 2014, to encourage voluntary anonymous HIV screening tests, the Seoul Metropolitan Government adopted a rapid HIV screening test at PHCs. The rapid HIV screening test was introduced at four PHCs in 2014 and all 25 PHCs after 2015. We compared the numbers of HIV screening tests and confirmed positive individuals before and after introduction of the rapid HIV screening test. In 2012-2013, before the introduction of rapid HIV screening test, an average of 330 HIV screening tests were performed monthly (355 in 2012 and 305 in 2013) and 69 individuals were confirmed to have HIV in 2012 and 93 in 2013. After the introduction of the rapid HIV screening test, anonymous voluntary HIV screening increased to a monthly average of 447 tests in 2014, 2099 in 2015, and 2409 in 2016. These identified 38 new cases in 2014, 116 in 2015, and 143 in 2016. Adoption of the rapid HIV screening test has increased the number of HIV screening tests and confirmed cases.

Peer distribution of HIV self-test kits to men who have sex with men to identify undiagnosed HIV infection in Uganda: A pilot study

Introduction

One-in-three men who have sex with men (MSM) in Uganda have never tested for HIV. Peer-driven HIV testing strategies could increase testing coverage among non-testers. We evaluated the yield of peer distributed HIV self-test kits compared with standard-of-care testing approaches in identifying undiagnosed HIV infection.

Methods

From June to August 2018, we conducted a pilot study of secondary distribution of HIV self-testing (HIVST) through MSM peer networks at The AIDS Support Organization (TASO) centres in Entebbe and Masaka. Peers were trained in HIVST use and basic HIV counselling. Each peer distributed 10 HIVST kits in one wave to MSM who had not tested in the previous six months. Participants who tested positive were linked by peers to HIV care. The primary outcome was the proportion of undiagnosed HIV infections. Data were analysed descriptively.

Results

A total of 297 participants were included in the analysis, of whom 150 received HIVST (intervention). The median age of HIVST recipients was 25 years (interquartile range [IQR], 22–28) compared to 28 years IQR (25–35) for 147 MSM tested using standard-of-care (SOC) strategies. One hundred forty-three MSM (95%) completed HIVST, of which 32% had never tested for HIV. A total of 12 participants were newly diagnosed with HIV infection: 8 in the peer HIVST group and 4 in the SOC group [5.6% vs 2.7%, respectively; P = 0.02]. All participants newly diagnosed with HIV infection received confirmatory HIV testing and were initiated on antiretroviral therapy.

Conclusion

Peer distribution of HIVST through MSM networks is feasible and effective and could diagnose more new HIV infections than SOC approaches. Public health programs should consider scaling up peer-delivered HIVST for MSM.

Estimating the costs and cost-effectiveness of HIV self-testing among men who have sex with men, United States

INTRODUCTION

HIV testing is an essential prerequisite for accessing treatment with antiretroviral therapy or prevention using pre-exposure prophylaxis. Internet distribution of HIV self-tests is a novel approach, and data on the programmatic cost of this approach are limited. We analyse the costs and cost-effectiveness of a self-testing programme.

METHODS

Men who have sex with men (MSM) reporting unknown or negative HIV status were enrolled from March to August 2015 into a 12-month trial of HIV self-testing in the United States. Participants were randomly assigned either to the self-testing arm or the control arm. All participants received information on HIV testing services and locations in their community. Self-testing participants received up to four self-tests each quarter, which they could use themselves or distribute to their social network associates. Quarterly follow-up surveys collected testing outcomes, including number of tests used and new HIV diagnoses. Using trial expenditure data, we estimated the cost of implementing a self-testing programme. Primary outcomes of this analysis included total programme implementation costs, cost per self-test completed, cost per person tested, cost per new HIV diagnosis among those self-tested and cost per quality adjusted life year (QALY) saved.

RESULTS

A total of 2665 men were assigned either to the self-testing arm (n = 1325) or the control arm (n = 1340). HIV testing was reported by 971 self-testing participants who completed a total of 5368 tests. In the control arm, 619 participants completed 1463 HIV tests. The self-testing participants additionally distributed 2864 self-tests to 2152 social network associates. Testing during the trial identified 59 participants and social network associates with newly diagnosed HIV infection in the self-testing arm; 11 control participants were newly diagnosed with HIV. The implementation cost of the HIV self-testing programme was $449,510. The cost per self-test completed, cost per person tested at least once, and incremental cost per new HIV diagnosis was $61, $145 and $9365 respectively. We estimated that self-testing programme potentially averted 3.34 transmissions, saved 14.86 QALYs and nearly $1.6 million lifetime HIV treatment costs.

CONCLUSIONS

The HIV self-testing programme identified persons with newly diagnosed HIV infection at low cost, and the programme is cost saving.

Effect of Internet-Distributed HIV Self-tests on HIV Diagnosis and Behavioral Outcomes in Men Who Have Sex With Men: A Randomized Clinical Trial

IMPORTANCE

Undiagnosed HIV infection results in delayed access to treatment and increased transmission. Self-tests for HIV may increase awareness of infection among men who have sex with men (MSM).

OBJECTIVE

To evaluate the effect of providing HIV self-tests on frequency of testing, diagnoses of HIV infection, and sexual risk behaviors.

DESIGN, SETTING, AND PARTICIPANTS

This 12-month longitudinal, 2-group randomized clinical trial recruited MSM through online banner advertisements from March through August 2015. Those recruited were at least 18 years of age, reported engaging in anal sex with men in the past year, never tested positive for HIV, and were US residents with mailing addresses. Participants completed quarterly online surveys. Telephone call notes and laboratory test results were included in the analysis, which was completed from August 2017 through December 2018.

INTERVENTIONS

All participants had access to online web-based HIV testing resources and telephone counseling on request. Participants were randomized in a 1:1 ratio to the control group or a self-testing (ST) group, which received 4 HIV self-tests after completing the baseline survey with the option to replenish self-tests after completing quarterly surveys. At study completion, all participants were offered 2 self-tests and 1 dried blood spot collection kit.

MAIN OUTCOMES AND MEASURES

Primary outcomes were HIV testing frequency (tested ≥3 times during the trial) and number of newly identified HIV infections among participants in both groups and social network members who used the study HIV self-tests. Secondary outcomes included sex behaviors (eg, anal sex, serosorting).

RESULTS

Of 2665 participants, the mean (SD) age was 30 (9.6) years, 1540 (57.8%) were white, and 443 (16.6%) had never tested for HIV before enrollment. Retention rates at each time point were more than 54%, and 1991 (74.7%) participants initiated 1 or more follow-up surveys. More ST participants reported testing 3 or more times during the trial than control participants (777 of 1014 [76.6%] vs 215 of 977 [22.0%]; P < .01). The cumulative number of newly identified infections during the trial was twice as high in the ST participants as the control participants (25 of 1325 [1.9%] vs 11 of 1340 [0.8%]; P = .02), with the largest difference in HIV infections identified in the first 3 months (12 of 1325 [0.9%] vs 2 of 1340 [0.1%]; P < .01). The ST participants reported 34 newly identified infections among social network members who used the self-tests.

CONCLUSIONS AND RELEVANCE

Distribution of HIV self-tests provides a worthwhile mechanism to increase awareness of HIV infection and prevent transmission among MSM.

Bringing HIV Self-Testing to Scale in the United States: a Review of Challenges, Potential Solutions, and Future Opportunities

HIV self-testing (HIVST) provides an at-home option to counter the barriers that patients face with testing performed in health care settings. HIVST has gradually increased in popularity in a time when social media and technology-based solutions are preferred. In this paper, we consider the aspects of self-testing that merit its integration into HIV testing and prevention systems in the United States. Several elements favor self-testing for large-scale implementation, including ease of use, convenience, potential for integration with mobile health (mHealth), and availability for various modes of distribution. HIVST has a demonstrated ability to reach at-risk individuals who otherwise rarely test. The paradigm of self-testing, however, introduces new challenges, including lesser test performance relative to that in health care settings, nonstandard counseling following receipt of test results, and difficulty in providing linkage to care. After discussing the performance of oral fluid versus blood-based HIVST, we review data regarding acceptability of HIVST, offer insights into counseling and linkage to care for HIVST, and provide examples of novel applications of and future research directions for HIVST.

Prevalence and Correlates of Point-of-sex Human Immunodeficiency Virus Self-testing Among Human Immunodeficiency Virus-negative Men Who Have Sex With Men in China

BACKGROUND

Human immunodeficiency virus (HIV) self-testing (HIVST) provides a promising tool to screen sex partners for men who have sex with men (MSM) who engage in condomless sex and want to avoid HIV infection. Although previous studies have demonstrated HIVST acceptability and increased testing uptake, limited data exist on its use between sex partners for point-of-sex HIV testing. This study examined prevalence and correlates of point-of-sex HIVST among Chinese MSM.

METHODS

A cross-sectional survey was conducted among 400 HIV-negative Chinese MSM in 2017. Participants were recruited through a multifaceted sampling approach and self-administered an electronic questionnaire. Point-of-sex HIVST was measured by asking participants if they had ever conducted HIVST with a sex partner before sex to ensure that they both knew their HIV statuses. Multivariable logistic regression was used to identify correlates of point-of-sex HIVST after controlling for age, education and sexual orientation.

RESULTS

Overall, 19.2% (77/400) men reported point-of-sex HIVST (51.3% among self-testers). Participants who had four or more HIV self-tests before had 7.57-fold greater odds (95% confidence interval, 3.75, 15.28) of reporting point-of-sex HIVST compared to those who had fewer HIVST experiences. Point-of-sex HIVST was otherwise not associated with most other socio-demographic or behavioral practices, suggesting that it may be broadly acceptable.

CONCLUSIONS

A substantial proportion of Chinese MSM had utilized HIVST with their partners before sex, especially among those who were more experienced with HIVST. Scale up and routine implementation of HIVST programs are further warranted to facilitate point-of-sex HIV testing.

High willingness to use novel HIV and bacterial sexually transmitted infection partner notification, testing, and treatment strategies among gay and bisexual men

OBJECTIVES

We sought to determine willingness of gay and bisexual men (GBM) to give HIV self-testing (HIVST) kits with patient-delivered partner therapy (PDPT) and engage in geosocial sexual networking (GSN) app-based partner notification.

METHODS

A nationwide sample of GBM who self-tested HIV negative (n=786) were asked about their willingness to give recent sex partners (main and casual) PDPT with an HIVST kit (PDPT+HIVST) after hypothetical bacterial STI (BSTI) diagnosis. Men were also asked about their willingness to notify sexual partners met on GSN apps using an anonymous app function after BSTI diagnosis. We examined associations of relationship status and condomless anal sex with casual partners, recent BSTI diagnosis and perceived risk of HIV on PDPT+HIVST and anonymous app-based partner notification willingness (dichotomised) using binary logistic regressions, adjusting for age, race/ethnicity, education and US region. From the partner's perspective after receiving an app-based referral, frequency measures were used to report intentions for obtaining subsequent HIV/BSTI counselling and testing, engaging in HIVST if provided a free voucher, and obtaining BSTI treatment from a pharmacy with prescription voucher.

RESULTS

Most (90.1%) were willing to give PDPT+HIVST to recent sex partners after STI diagnosis, and nearly all (96.4%) were willing to notify sex partners met online using an anonymous function within GSN apps. Regardless of casual partner condomless anal sex engagement, partnered GBM had higher odds of reporting willingness to give PDPT+HIVST compared with single men who recently engaged in condomless anal sex with a casual partner. If anonymously notified via an app, 92.5% reported they would likely obtain counselling and testing, 92.8% would engage in HIVST if provided a free voucher, and 93.4% would obtain treatment from a pharmacy with prescription voucher.

CONCLUSIONS

GBM generally found novel partner notification, testing, and treatment strategies acceptable, indicating the need for feasibility and cost-effectiveness evaluations.

Acceptability and Feasibility of Self-Collecting Biological Specimens for HIV, Sexually Transmitted Infection, and Adherence Testing Among High-Risk Populations (Project Caboodle!): Protocol for an Exploratory Mixed-Methods Study

BACKGROUND

Men who have sex with men (MSM) in the United States experience a disproportionate burden of HIV and bacterial sexually transmitted infections (STIs), such as gonorrhea and chlamydia. Screening levels among MSM remain inadequate owing to barriers to testing such as stigma, privacy and confidentiality concerns, transportation issues, insufficient clinic time, and limited access to health care. Self-collection of specimens at home and their return by mail for HIV and bacterial STI testing, as well as pre-exposure prophylaxis (PrEP) adherence monitoring, could be a resource-efficient option that might mitigate some of these barriers.

OBJECTIVE

Project Caboodle! is a mixed-methods study that explores the acceptability and feasibility of self-collecting and returning a bundle of 5 different specimens for HIV and bacterial STI testing, as well as PrEP adherence monitoring, among sexually active HIV-negative or unknown status MSM in the United States aged 18 to 34 years.

METHODS

Participants will be recruited using age, race, and ethnicity varied advertising on social networking websites and mobile gay dating apps. In Phase 1, we will send 100 participants a box containing materials for self-collecting and potentially returning a finger-stick blood sample (for HIV testing), pharyngeal swab, rectal swab, and urine specimen (for gonorrhea and chlamydia testing), and hair sample (to assess adequacy for potential PrEP adherence monitoring). Specimen return will not be incentivized, and participants can choose to mail back all, some, or none of the specimens. Test results will be delivered back to participants by trained counselors over the phone. In Phase 2, we will conduct individual in-depth interviews using a video-based teleconferencing software (VSee) with 32 participants from Phase 1 (half who returned all specimens and half who returned some or no specimens) to examine attitudes toward and barriers to completing various study activities.

RESULTS

Project Caboodle! was funded in May 2018, and participant recruitment began in March 2019. The processes of designing a study logo, creating advertisements, programming Web-based surveys, and finalizing step-by-step written instructions accompanied by color images for specimen self-collection have been completed. The boxes containing 5 self-collection kits affixed with unique identification stickers are being assembled, and shipping procedures (for mailing out boxes to participants and for specimen return by participants using prepaid shipping envelopes) and payment procedures for completing the surveys and in-depth interviews are being finalized.

CONCLUSIONS

Self-collection of biological specimens at home and their return by mail for HIV and bacterial STI testing, as well as PrEP adherence monitoring, might offer a practical and convenient solution to improve comprehensive prevention efforts for high-risk MSM. The potentially reduced time, expense, and travel associated with this approach could facilitate a wider implementation of screening algorithms and remote monitoring strategies.

Distribution of HIV Self-tests by HIV-Positive Men Who Have Sex with Men to Social and Sexual Contacts

HIV-positive men who have sex with men (MSM) were recruited on www.Facebook.com and www.Poz.com to give HIV self-tests to their contacts. Study participants completed a baseline survey, were given two self-tests, and completed a survey 2 months later. Of 133 eligible men, 40 (30%) completed both surveys. Most participants were 30-54 years old and non-Hispanic white. Some had a detectable viral load (n = 4), had condomless anal sex with male partners of negative or unknown status (n = 17), and had met anal sex partners at gay dating websites (n = 23). Of 80 self-tests given to participants, 59 (74%) were distributed, primarily to non-Hispanic white MSM, 30-54 years old who were friends. Participants reported results from 31 distributed tests; 2 sex partners of participants had positive results. Participants indicated these two persons were unaware of their infections. Expanding recruitment websites might reach non-white MSM. Unrecognized infections were identified through online recruitment and self-test distribution via HIV-positive persons.

Acceptability, perceived reliability and challenges associated with distributing HIV self-test kits to young MSM in Uganda: a qualitative study

INTRODUCTION

HIV self-testing is a flexible, accessible and acceptable emerging technology with a particular potential to identify people living with HIV who are reluctant to interact with conventional HIV testing approaches. We assessed the acceptability, perceived reliability and challenges associated with distributing HIV self-test (HIVST) to young men who have sex with men (MSM) in Uganda.

METHODS

Between February and May, 2018, we enrolled 74 MSM aged ≥18 years purposively sampled and verbally consented to participate in six focus group discussions (FGDs) in The AIDS Support Organization (TASO Masaka and Entebbe). We also conducted two FGDs of 18 health workers. MSM FGD groups included individuals who had; (1) tested greater than one year previously; (2) tested between six months and one year previously; (3) tested three to six months previously; (4) never tested. FGDs examined: (i) the acceptability of HIVST distribution; (iii) preferences for various HIVST distribution channels; (iv) perceptions about the accuracy of HIVST; (v) challenges associated with HIVST distribution. We identified major themes, developed and refined a codebook. We used Nvivo version 11 for data management.

RESULTS

MSM participants age ranged between 19 and 30 years. Participants described HIVST as a mechanism that would facilitate HIV testing uptake in a rapid, efficient, confidential, non-painful; and non-stigmatizing manner. Overall, MSM preferred HIVST to the conventional HIV testing approaches. Health workers were in support of distributing HIVST kits through MSM peers. MSM participants were willing to distribute the kits and recommended HIVST to their peers and sexual partners. They suggested HIVST kit distribution model work similarly to the current condom and lubricant peer model being implemented by TASO. Preferred channels were peers, hot spots, drop-in centres, private pharmacies and MSM friendly health facilities. Key concerns regarding use of HIVST were; unreliable HIVST results, social harm due to a positive result, need for a confirmatory test and linking both HIV positive and negative participants for additional HIV services.

CONCLUSIONS

Distribution of HIVST kits by MSM peers is an acceptable strategy that can promote access to testing. HIVST was perceived by participants as beneficial because it would address many barriers that affect their acceptance of testing. However, a combined approach that includes follow-up, linkage to HIV care and prevention services are needed for effective results.

Men Who Have Sex with Men (MSM) Who Have Not Previously Tested for HIV: Results from the MSM Testing Initiative, United States (2012-2015)

The Centers for Disease Control and Prevention recommends annual HIV tests for men who have sex with men (MSM), yet some have never tested. We analyzed data from the MSM Testing Initiative. Of 68,185 HIV tests, 8% were with MSM who never previously tested ("first-time testers"). Among tests with first-time testers, 70.7% were with MSM from racial or ethnic minorities; 66.5% were with MSM younger than 30 years. Tests with MSM who reported female partners only during the past year (compared to male partners only) or were recruited for at-home testing (compared to venue-based recruitment) were 4 times (prevalence ratio [PR] 3.62, 95% CI 3.15-4.15) and 5 times as likely (PR 4.69, 95% CI 4.22-5.21) to be associated with first-time testing. At-home testing and focusing on MSM who have sex with women may be effective methods for reaching MSM who are first-time testers.

Effectiveness of self-testing kits availability on improving HIV testing frequency for chinese men who have sex with men and their sexual partners: a protocol for a multicenter randomised controlled trial

INTRODUCTION

HIV epidemic is increasing among men who have sex with men (MSM) in China, yet HIV testing uptake remains low. As an emerging approach, HIV self-testing (HIVST) has the potential to promote HIV testing coverage and frequency in this population. However, evidence of the effectiveness on implementation of HIVST among Chinese MSM and their sexual partners is scarce.

METHODS AND ANALYSIS

The randomised controlled trial will be performed in Changsha, Changde, Shaoyang and Yiyang, Hunan province, China, recruiting 184 recent testers (men who had at least one HIV test within the past 2 years) and 26 non-recent testers (men who did not have HIV tests within 2 years or never had an HIV test). Eligible men will be randomly divided 1:1 into two groups: intervention (with free HIVST kits plus site-based HIV testing services) and control (site-based HIV testing services only). Participants in the intervention group will be provided with two free finger-prick-based HIVST kits, and can apply for two to four kits every 3 months for 1 year.Participants in both groups will complete questionnaires via WeChat at five separate times: baseline, third, sixth, ninth and twelfth month. The primary outcome is the mean number of HIV tests for MSM over the 12-month study period. The secondary outcome is the mean number of HIV tests for sexual partners of MSM over the 12-month study period. The tertiary outcomes are the self-reported proportion of consistent condom usage for anal sex, and the numbers of sexual partners during the 12-month study period.

ETHICS AND DISSEMINATION

The study has been approved by the Institutional Review Board of Behavioural and Nursing Research in Xiangya School of Nursing of Central South University, China (2018002). Study results will be disseminated through conferences and academic journals.

Perceptions of HIV Self-Testing Among Men Who Have Sex With Men in the United States: A Qualitative Analysis

HIV testing is the gateway into both prevention and treatment services. It is important to understand how men who have sex with men (MSM) perceive HIV self-tests. We conducted focus groups and individual interviews to collect feedback on two HIV self-tests, and on a dried blood spot (DBS) specimen collection kit. Perceptions and attitudes around HIV self-testing (HIVST), and willingness to distribute HIV self-tests to others were assessed. MSM reported HIVST to be complementary to facility-based testing, and liked this approach because it offers privacy and convenience, does not require counseling, and could lead to linkage to care. However, they also had concerns around the accuracy of HIV self-tests, their cost, and receiving a positive test result without immediate access to follow-up services. Despite these issues, they perceived HIVST as a positive addition to their HIV prevention toolbox.

Pilot Evaluation of the Ability of Men Who Have Sex with Men to Self-Administer Rapid HIV Tests, Prepare Dried Blood Spot Cards, and Interpret Test Results, Atlanta, Georgia, 2013

In the United States, an estimated 67% of new HIV diagnoses are among men who have sex with men (MSM), however 25% of HIV-positive MSM in the 2014 National HIV Behavioral Surveillance Survey were unaware of their infection. HIV self-testing (HIVST) with rapid diagnostic tests (RDTs) may facilitate access to HIV testing. We evaluated the ability of 22 MSM to conduct two HIV RDTs (OraQuick ^® In-Home HIV Test and a home-use prototype of Sure Check ^® HIV 1/2 Assay), interpret sample images of test results, and collect a dried blood spot (DBS) specimen. While some participants did not follow every direction, most participants were able to conduct HIVST and correctly interpret their results. Interpretation of panels of RDT images was especially difficult when the "control" line was missing, and 27% of DBS cards produced were rated as of bad quality. Modifications to the DBS instructions were necessary prior to evaluating the performance of these tests in real-world settings.
