HIV self-testing among key populations: an implementation science approach to evaluating self-testing

Implementation determinants of HIV Self-Testing among young sexual minority men

BACKGROUND

HIV self-testing (HIVST) has shown the potential for reaching people with heightened vulnerability to HIV, including young sexual minority men (YSMM), yet implementation of HIVST among YSMM aged 17-24 is scarce as a prevention method. Moreover, despite the consistent finding that offering HIVST increases HIV testing rates, barriers remain that need to be reduced in order to maximize the potential of this biomedical technology. Such information is necessary to direct implementation efforts to increase HIVST among YSMM, including HIV counseling and linkage to care. The current study was therefore intended to investigate perspectives for HIVST among YSMM and how HIVST can be marketed to increase implementation.

METHODS

Between March and September 2020, we enrolled 41 YSMM to participate in one of nine online synchronous focus group discussions about their general experience with HIV preventive services. Guided by the Consolidated Framework (CFIR) for Implementation Research, we explored YSMM perspectives on facilitators and barriers to HIVST implementation. Data were analyzed using a deductive thematic content analysis approach.

RESULTS

Many participants had never used HIVST before their participation in this study (n = 30; 73.2%). Qualitative results exhibited a variety of implementation determinants across the five CFIR 2.0 domains. Barriers included concerns about the format in which the testing materials would be provided (i.e., nature of packaging) and about the method in which the sample would need to be collected, particularly for those who had the testing kit mailed to their home address. These reservations were nested in the fear of unwanted disclosure of their sexual behavior, namely among the respondents who had to cohabitate with family due to the COVID-19 pandemic. Participants also discussed the limited local resources for HIVST. Many participants suggested programs that could be implemented to support HIVST, such as collaborations with trusted community agencies.

CONCLUSIONS

Understanding YSMM' perspectives of HIVST may help identify implementation deficiencies within the delivery system and aid the development of implementation strategies to promote reach of HIVST.

HIV Self-testing and Risk Behaviors Among Men Who Have Sex With Men in 23 US Cities, 2017

IMPORTANCE

HIV self-testing (HIVST) is a promising strategy to expand the HIV care continuum, particularly among priority populations at high risk of HIV infection. However, little is known about HIVST uptake among men who have sex with men (MSM) outside of clinical trial settings.

OBJECTIVE

To evaluate HIVST use among urban MSM in the US who reported testing within the past 12 months.

DESIGN, SETTING, AND PARTICIPANTS

A cross-sectional study of adult MSM in the 2017 National HIV Behavioral Surveillance system, which used venue-based sampling methods to collect data related to HIV testing, receipt of prevention services, and risk factors for HIV, was conducted at 588 venues in 23 urban areas in the contiguous US and Puerto Rico. All participants were offered HIV testing. Adult cisgender MSM who reported HIV-negative or unknown HIV status and obtained HIV testing in the past 12 months were included. Data for this study were collected between June 4, 2017, and December 22, 2017, and analyzed between October 23, 2020, and August 20, 2021.

MAIN OUTCOMES AND MEASURES

Self-reported HIVST in the past year. Adjusted prevalence ratios (aPRs) using survey weights were calculated to assess factors associated with HIVST.

RESULTS

A total of 6563 MSM in 23 urban areas met inclusion criteria, of whom 506 (7.7%) individuals reported HIVST in the past year. The median age of self-testers was 29 (IQR, 25-35) years, 52.8% had completed college, and 37.9% reported non-Hispanic White race. One self-tester reported seroconverting in the prior 12 months, and an additional 10 self-testers were diagnosed with HIV during the survey. HIVST was associated with sexual orientation disclosure (aPR, 10.27; 95% CI, 3.45-30.60; P < .001), perceived discrimination against people with HIV (aPR, 1.53; 95% CI, 1.09-2.03; P = .01), younger age (aPR, 0.74; 95% CI, 0.66-0.84; P < .001), higher educational level (aPR, 1.20; 95% CI, 1.04-1.37; P = .01), and higher income levels (aPR, 1.18; 95% CI, 1.04-1.32; P = .009). No association was noted with condomless anal sex (aPR, 0.96; 95% CI, 0.88-1.06, P = .88), sexually transmitted infections (aPR, 0.96; 95% CI, 0.70-1.30; P = .77), or preexposure prophylaxis use (aPR, 0.99; 95% CI, 0.75-1.30; P = .92).

CONCLUSIONS AND RELEVANCE

In this study, HIVST was relatively uncommon in this sample of urban MSM. HIVST may not be reaching those with lower socioeconomic status or who have not disclosed their sexual identity. The findings of this study suggest that efforts to increase HIVST should focus on engaging underserved and vulnerable subgroups of MSM.

Supporting the Growth of Domestic HIV Implementation Research in the United States Through Coordination, Consultation, and Collaboration: How We Got Here and Where We Are Headed

BACKGROUND

The Ending the HIV Epidemic (EHE) initiative sets a goal to virtually eliminate new HIV infections in the United States by 2030. The plan is predicated on the fact that tools exist for diagnosis, prevention, and treatment, and the current scientific challenge is how to implement them effectively and with equity. Implementation research (IR) can help identify strategies that support effective implementation of HIV services.

SETTING

NIH funded the Implementation Science Coordination Initiative (ISCI) to support rigorous and actionable IR by providing technical assistance to NIH-funded projects and supporting local implementation knowledge becoming generalizable knowledge.

METHODS

We describe the formation of ISCI, the services it provided to the HIV field, and data it collected from 147 NIH-funded studies. We also provide an overview of this supplement issue as a dissemination strategy for HIV IR.

CONCLUSION

Our ability to reach EHE 2030 goals is strengthened by the knowledge compiled in this supplement, the services of ISCI and connected hubs, and a myriad of investigators and implementation partners collaborating to better understand what is needed to effectively implement the many evidence-based HIV interventions at our disposal.

The study of feasibility and acceptability of using HIV self-tests in high-risk Iranian populations (FSWs, MSM, and TGs): a cross-sectional study

Background

This study aimed to evaluate the feasibility of using the HIV self-test in high-risk Iranian groups (MSM, FSWs, and TGs).

Methods

This study was a mixed study designed as a quantitative–qualitative study conducted between October 1, 2020, and June 22, 2021, in Tehran and Karaj, Iran. The sample size needed for this study generally was 1000 people, including FSWs, MSM, and transgender individuals. Convenience and snowball sampling methods were used to collect the samples.

Results

A total of 930 eligible respondents were enrolled in the study, of whom 456 (49%) were female and 49 (5.3%) were transgender (98% of TGs were male to female), and their mean age was 33.63 years (10.54 SD). The feasibility of using HIV self-tests in Iranian high-risk groups was significantly high. The majority of participants (97%) did not have any confidentiality problems while preparing or performing the test. In general, feasibility was assessed based on five questions. The overall feasibility score was 6.33 (0.824 SD). Taking tests, reading HIV test results, finding a safe place to do the test, and accessing HIV self-tests showed a high average.

Conclusion

HIV self-testing was highly acceptable and feasible among high-risk populations, so routine HIV testing was efficiently possible.

HCV Self-Testing to Expand Testing: A Pilot Among Men Who Have Sex With Men in China

Background

Hepatitis C virus self-testing (HCVST) may increase test uptake especially among marginalized key populations such as men who have sex with men (MSM). We conducted an observational study to assess the usability, acceptability and feasibility of HCVST among MSM in China.

Methods

An observational study with convenience sampling was performed among MSM in Guangzhou, China in 2019. The OraQuick® HCV Rapid Antibody Test kits were used in this study. Participants performed all 12 HCVST steps and interpreted the results in the presence of a trained observer. Usability was defined as the number and percentage of participants who completed all testing steps correctly without assistance and interpreted the results correctly. Inter-reader concordance was calculated as the percentage agreement between the results interpreted by the participant and those interpreted by a trained staff member. The same process was used to estimate inter-operator agreement between the self-testing and professional use test results. Acceptability was assessed using an interviewer-administered semi-structured questionnaire.

Results

Among 100 participants with median age 27 (interquartile range 23-30) years, 4% reported prior history of HCV testing, 41% reported using blood-based HIV self-testing in the past, 54% (95%CI: 43.7-64.0%) completed all self-testing steps correctly without assistance and interpreted the results correctly. Both the inter-reader and inter-operator concordance were excellent at 97% (95%CI: 91.5-99.4%) and 98% (95%CI: 93.0-99.8%), respectively. The majority rated the HCVST process as very easy (52%, 95%CI: 41.8-62.1%) or easy (41%, 95%CI: 31.3-51.3%), 76% (95%CI: 66.4-84.0%) were willing to use HCVST again, and 75% (95%CI: 65.3-83.1%) would recommend it to their family and friends.

Conclusions

Our findings demonstrate that oral fluid HCVST has high usability and acceptability among Chinese MSM. More implementation research is needed to plan how best to position and scale-up HCVST alongside other facility-and community-based testing approaches and ensure data linkage into health systems.

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

Background

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

Objectives

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

Method

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

Results

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

Conclusion

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

The 4 Youth by Youth (4YBY) pragmatic trial to enhance HIV self-testing uptake and sustainability: Study protocol in Nigeria

BACKGROUND

The World Health Organization recommends HIV self-testing (HIVST) as an additional approach to HIV testing and the Nigerian government is supportive of this policy recommendation. However, effectively increasing uptake and sustainability among Nigerian youth is unknown. The goal of this study is to conduct a full-powered type I hybrid effectiveness-implementation trial to test the effectiveness of youth-friendly implementation science strategies in increasing uptake and sustainability of HIVST led by and for Nigerian youth.

METHODS

Our 4 Youth by Youth (4YBY) strategy combines four core elements: 1) HIVST bundle consisting of HIVST kits and photo verification system; 2) a participatory learning community; 3) peer to peer support and technical assistance; and 4) on-site supervision and performance feedback to improve uptake and sustainability of HIVST and enhance linkage to youth-friendly health clinics for confirmatory HIV testing where needed, sexually transmitted infection (STI) testing (i.e. syphilis, gonorrhea, chlamydia, and hepatitis, STI treatment, and PrEP referral. Utilizing a stepped-wedge, cluster-randomized controlled trial, a national cohort of youth aged 14-24 recruited from 32 local government areas across 14 states and four geo-political zones in Nigeria will receive the 4YBY implementation strategy. In addition, an economic evaluation will explore the incremental cost per quality adjusted life year gained.

DISCUSSION

This study will add to the limited "how-to-do it literature" on implementation science strategies in a resource-limited setting targeting youth population traditionally underrepresented in implementation science literature. Study findings will also optimize uptake and sustainability of HIVST led by and for young people themselves.

TRIAL REGISTRATION

This study is registered in ClinicalTrials.govNCT04710784 (on January 15, 2021).

Values and preferences for hepatitis C self-testing among the general population and healthcare workers in Rwanda

Background

In 2018, Rwanda launched a 5-year hepatitis C virus (HCV) elimination plan as per the World Health Organization global targets to eliminate HCV by 2030. To improve awareness of HCV status, strategies are needed to ensure easy access to HCV testing by as-yet unreached populations. HCV-self-testing, an innovative strategy, could further increase HCV testing uptake. This assessment explores perceptions around HCV self-testing among members of the public and healthcare workers in Rwanda.

Methods

A qualitative study was undertaken in Masaka District Hospital, comprising individual interviews, group interviews and participatory action research (PAR) activities. Purposive and snowball sampling methods guided the selection of informants. Informed consent was obtained from all participants. A thematic analysis approach was used to analyse the findings.

Results

The participants comprised 36 members of the public and 36 healthcare workers. Informants appreciated HCV self-testing as an innovative means of increasing access to HCV testing, as well as an opportunity to test privately and subsequently autonomously decide whether to seek further HCV care. Informants further highlighted the need to make HCV self-testing services free of charge at the nearest health facility. Disadvantages identified included the lack of pre/post-test counselling, as well as the potential psychosocial harm which may result from the use of HCV self-testing.

Conclusion

HCV self-testing is perceived to be an acceptable method to increase HCV testing in Rwanda. Further research is needed to assess the impact of HCV self-testing on HCV cascade of care outcomes.

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.

The 4 youth by youth HIV self-testing crowdsourcing contest: A qualitative evaluation

INTRODUCTION

Crowdsourcing, a participatory approach to solicit ideas from a large group of diverse individuals, provides an opportunity to nurture youth participation in HIV self-testing service design. The objective of this study was to describe the responses to a crowdsourcing contest aimed at soliciting ideas on how to promote HIV self-testing (HIVST) among young people in Nigeria.

METHODS

The "4 Youth by Youth" HIV Self-Testing Crowdsourcing contest was an online and off-line contest that asked Nigerian youth (10-24 years old) for ideas in response to the following: How might we promote HIVST among young people in Nigeria? All data were collected and analyzed between October 2018, and June 2019. Ideas and perceptions generated from the crowdsourcing contest were qualitatively analyzed using thematic content analysis. Specifically, four reviewers analyzed whether the ideas generated were desirable (appealing to young people), feasible (easy to implement) and impactful (will significantly influence HIVST uptake among young people).

RESULTS

A total of 903 entries were received in response to the contest prompt. Participants submitted entries in various forms: online form (39.7%), offline Dropbox (44.6%), email (6.1%) and WhatsApp (9.7%). Of the total entries, 85% (n = 769/903) entries were eligible and were scored as having either high, moderate or low level of feasibility, impact and desirability, on a 3-point Likert scale. A significant portion of the entries were given a score of 3 for feasibility (4.9%), desirability (7.1%), impact (3.0%) or a total overall score of 7 or more (8.2%). The three main themes that emerged from the entries include:1) Peer-to-peer distribution and leveraging on existing infrastructures 2) Youth-Oriented Branding of the HIVST Kit 3) Mobile platforms and social media technology.

CONCLUSION

The "4 Youth by Youth" Self-Testing contest engaged a broad audience of young people to generate ideas and perspectives on how to promote HIVST. This process informed the development of youth innovated implementation strategies to increase uptake of HIVST among adolescents and youth at risk for HIV.

Providing competent, comprehensive and inclusive sexual health services for men who have sex with men in low- and middle-income countries: a scoping review

Although men who have sex with men (MSM) are disproportionately affected by HIV and other sexually transmissible infections, sexual health services for MSM in low- and middle-income countries (LMIC) remain under-resourced and are poorly understood. A scoping review of literature on MSM sexual health in LMIC was conducted in order to identify key clinical services and gaps in knowledge. Three databases were searched, in addition to hand-reviewing key journals and bulletins, to identify literature with a focus on MSM sexual health. Key services related to providing care to MSM in LMIC that emerged from our review are described. These services include creation of safe and confidential clinic environments, HIV testing services, behavioural interventions, HIV pre-exposure prophylaxis (PrEP), rapid antiretroviral therapy (ART) initiation and STI services. Compared with high-income settings, major differences in LMIC include lack of diagnostic technology, unfavourable legal environments and lack of funding for MSM health. Innovative approaches to healthcare delivery, such as harnessing mobile technology, self-testing and crowdsourcing interventions, can improve health services among MSM in LMIC. There are gaps in the evidence about how best to provide sexual health services for MSM in LMIC settings. Implementation research and scale-up of existing biomedical and behavioural interventions, such as HIV/STI testing services, PrEP and early antiretroviral initiation are urgently needed in LMIC.

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.

A pilot trial of the peer-based distribution of HIV self-test kits among fishermen in Bulisa, Uganda

BACKGROUND

HIV self-testing (HIVST) addresses barriers to HIV diagnosis among men, but current approaches to distributing HIVST kits only reach a subset of the men requiring testing.

METHODS

We conducted a pilot trial of the secondary distribution of HIVST kits through peer networks in fishing communities of Buliisa district (Uganda). We recruited distributors ("seeds") among male patients of a health facility, and among community members. Seeds were trained in HIVST and asked to distribute up to five kits to their peers ("recruits"). Recruits were referred to the study using a coupon, and asked to return the HIVST kit (used or unused). The accuracy of HIVST was measured against a confirmatory test conducted by a health worker. We conducted audio computer assisted self-interviews to measure the occurrence of adverse events, and evaluate the potential yield of peer-delivered HIVST. We also assessed how seeds and recruits rated their experience with peer-distributed HIVST.

RESULTS

Nineteen seeds offered an HIVST kit to 116 men, and 95 (81.9%) accepted the offer. No recruit reported coercion, but two seeds experienced hostility from recruits or their family members. The sensitivity of peer-distributed HIVST, as interpreted by recruits, was 100%, and its specificity was 92.8%. Among recruits, 29 had never tested (25.8%), and 42 (44.2%) had tested more than a year ago. Three men living with HIV learned their status through peer-distributed HIVST (yield = 1 new diagnosis per 6.3 seeds). Most recruits (85/88) and seeds (19/19) reported that they would recommend HIVST to their friends and family. All seeds stated that they would accept acting as peer distributors again.

CONCLUSIONS

This novel peer-based distribution model of HIVST is safe, and has high uptake. It could help reduce the gender gap in HIV testing in under-served fishing communities in Uganda and elsewhere.

Uptake of HIV self-testing and linkage to treatment among men who have sex with men (MSM) in Nigeria: A pilot programme using key opinion leaders to reach MSM

INTRODUCTION

HIV self-testing (HIVST) offers an alternative to facility-based HIV testing services, particularly for populations such as men who have sex with men (MSM) who may fear accessing testing due to stigma, discrimination and criminalization. Innovative HIV testing approaches are needed to meet the goal of 90% of people living with HIV being diagnosed. This study piloted an intervention to distribute oral HIVST kits to MSM through key opinion leaders (KOLs) in Lagos, Nigeria and assessed the feasibility, acceptability, uptake of HIVST and linkage to HIV treatment.

METHODS

A cohort study was conducted (May through September 2017) with 319 participants who were recruited by 12 KOLs through their networks. A baseline survey was conducted at the time of the oral HIVST kit (OraQuick® HIV antibody test) distribution to eligible MSM followed by a 3-month follow-up survey to assess usage of and experience with the HIVST kits. Each participant was given two kits.

RESULTS

The median age of the participants was 25 years, 88.7% were literate and 17.9% were first-time testers. Of the 257 participants (80.7% retention) who completed the three-month follow-up interview, 97.7% reported using the HIVST kit and 14 (5.6%) self-reported an HIV positive result. A quarter (22.7%) tested themselves the same day they received the kit, and 49.4% tested within one week. Almost all participants reported that the HIVST kit instructions were easy or somewhat easy to understand (99.6%) and perform the test (98.0%). The most common reasons they liked the test were ease of use (87.3%), confidentiality/privacy (82.1%), convenience (74.1%) and absence of needle pricks (64.9%). All 14 participants who tested positive had sought confirmatory testing and initiated HIV treatment by the time of the three-month survey.

CONCLUSIONS

HIVST distribution through KOLs was feasible and oral self-testing was highly acceptable among this urban MSM population. Despite concerns about linkage to treatment when implementing self-testing, this study showed that linkage to treatment can be achieved with active follow-up and access to a trusted MSM-friendly community clinic that offers HIV treatment. HIVST should be considered as an additional option to standard HIV testing models for MSM.

Experiences using and organizing HIV self-testing

OBJECTIVE

HIV self-testing (HIVST) is now officially recommended by the WHO, yet much of HIVST evidence to date has focused on quantitative data and hypothetical concerns. Effective scale-up of HIVST in diverse local contexts requires qualitative data from experiences using and organizing HIVST. This qualitative systematic review aims to appraise and synthesize research evidence on experiences using and organizing HIVST.

METHODS

We conducted a systematic search of seven primary literature databases, four gray literature sources, and reference lists reporting qualitative evidence on HIVST. Data extraction and thematic analysis were used to synthesize findings. Quality of studies was assessed using the Critical Appraisal Skills Programme tool. Confidence in review findings was evaluated using the Confidence in the Evidence from Reviews of Qualitative Research approach. The review protocol was registered (CRD42015027607).

RESULTS

From 1266 potential articles, we included 18. Four studies were conducted in low-income countries, three in middle-income countries, 10 in high-income countries, and one in multiple countries. Generally, HIVST increased capacity to reach priority populations and expanded opportunities for service delivery. Self-testing was preferred to facility-based testing due to increased convenience and confidentiality, especially among stigmatized populations. HIVST decreased test-associated stigma compared with facility-based testing. HIVST generally empowered people because it provided greater control over individual testing needs. At the same time, HIVST rarely allowed husbands to coerce their wives to test.

CONCLUSIONS

This review suggests that HIVST should be offered as an additional HIV testing option to expand testing and empower testers. Adapting national policies to incorporate HIVST will be necessary to guide scale-up.

The future of viral hepatitis testing: innovations in testing technologies and approaches

A large burden of undiagnosed hepatitis virus cases remains globally. Despite the 257 million people living with chronic hepatitis B virus infection, and 71 million with chronic viraemic HCV infection, most people with hepatitis remain unaware of their infection. Advances in rapid detection technology have created new opportunities for enhancing access to testing and care, as well as monitoring of treatment. This article examines a range of other technological innovations that can be leveraged to provide more affordable and simplified approaches to testing for HBV and HCV infection and monitoring of treatment response. These include improved access to testing through alternative sampling methods (use of dried blood spots, oral fluids, self-testing) and combination rapid diagnostic tests for detection of HIV, HBV and HCV infection; more affordable options for confirmation of virological infection (HBV DNA and HCV RNA) such as point-of-care molecular assays, HCV core antigen and multi-disease polyvalent molecular platforms that make use of existing centralised laboratory based or decentralised TB and HIV instrumentation for viral hepatitis testing; and finally health system improvements such as integration of laboratory services for procurement and sample transportation and enhanced data connectivity to support quality assurance and supply chain management.
