Four models of HIV counseling and testing: utilization and test results in South Africa

HIV and sexual risk behaviours by 18-25-year-old youth at Nyandeni Municipality in the Eastern Cape

Background

The human immunodeficiency virus (HIV) epidemic in South Africa is among the worst in the world; in 2017, 38% of new infections were among young people aged 15-24 years. Estimates for HIV infection in 2020 worldwide indicate that there will be 1.5 million new cases, 10.2 million untreated cases (out of 37.7 million), and 680 000 deaths from acquired immunodeficiency syndrome (AIDS). Despite a 46% decline in new HIV infections among adolescents and youth over the previous 10 years, two of the seven new HIV infections in 2019 occurred in people between the ages of 15 and 24. HIV prevalence among young people has remained unchanged since 2008. This consistent pattern among people under 30 years of age indicates a failure in HIV prevention.

Aim

The study aimed to explore HIV and sexual risk behaviours by 18-25-year-old youth at Nyandeni Municipality in the Eastern Cape province.

Setting

The investigation was conducted Nyandeni Municipality in the Eastern Cape province.

Methods

Qualitative approach was used to explore, describe and investigate the knowledge and attitudes about HIV among the 18-25 years old youth.

Results

The findings are based on three themes namely, knowledge and attitudes about HIV and AIDS in youth, sexual risk behaviour among youth, and HIV prevention strategies.

Conclusion

This exploratory investigation confirms that the participants' knowledge is limited by showing that most of them knew very little about HIV and AIDS infection and prevention. Ongoing educational initiatives are required.

Contribution

Youth experience high HIV incidence because of their knowledge gaps.

Primary Health Center: Can it be made mobile for efficient healthcare services for hard to reach population? A state-of-the-art review

Indian healthcare system is in immediate need of a new healthcare delivery model to increase healthcare accessibility and improve the health outcomes of the marginalized. Inaccessibility and underutilization of Primary Health Centers (PHCs) disproportionately affect people living in remote areas. It is thus imperative for the designers, engineers, health professionals, and policymakers to come together with a collaborative mindset to develop innovative interventions that sustainably manage the accessibility of PHCs at large, promote preventive health, and thus improve the health outcomes of hard-to-reach communities. This article examines the available literature on barriers to primary healthcare in Indian context, the reason of failure of PHCs and the way forward. The article further analysis literature on existing Mobile Medical Units (MMUs) as an alternate solution to conventional PHCs and attempt to extract the major lessons to propose a mobile Primary Health Center (mPHC) in contrast to the existing conventional static PHCs. The intention is to find out the research gaps in the existing literature and try to address the same for future researchers, designers, engineers, health professionals and policy makers to think forward to make this idea of a mobile Primary Health Center (mPHC), as the main delivery model to cater basic healthcare services to the underserved communities.

Making primary healthcare delivery robust for low resource settings: Learning from Mohalla Clinics

The present healthcare scenario is still in its compromised state, whether it is the lack of infrastructure, medicines and human resources, especially in rural India. Moreover, the condition worsens in rural areas due to several reasons like lack of awareness, proper roads to access, and lack of proper delivery of healthcare model. The state government of Delhi, India, set up the "Mohalla" Clinics to provide essential healthcare to residents of Delhi and the surrounding areas, focusing on the urban poor. Essential health services, such as vaccinations, family planning, and counselling, are available at the Mohalla Clinics, where a doctor, a nurse, a pharmacist, and a lab technician are staffed. Despite a strong start and low operating costs, the Mohalla Clinic initiative still struggles to cover all Delhi state as envisioned. This study analyses the operational challenges of Delhi's "Mohalla" Clinics and proposes lessons to be implemented for other primary healthcare infrastructure services for remote areas. The analysis is based on the systems (infrastructure, facilities, and services) strengths and limitations from a literature review and qualitative interview conducted among 55 respondents, including doctors, nurses, and patients among 11 Mohalla Clinics using the SUTD-MIT (Singapore University of Technology and Design-Massachusetts Institute of Technology Industrial Design Centre) interview template for Product Service System (PSS). The results show that there are lessons to learn from the model of Delhi Mohalla Clinics for other states to implement in their primary healthcare sectors. To achieve Universal Health Coverage (UHC), the Delhi Mohalla Clinic falls short due to several limitations. Thus, to achieve UHC, the Indian healthcare system needs a new healthcare delivery model. Hence, we ought to propose a new healthcare delivery model based on the gained insights from the study. One such delivery model proposed is a mobile Primary Health Center (mPHC). This collapsible system can be taken to far-flung regions, deployed for some hours, run the Out-Patient Department (OPD), collapsed, and returned to base.

A systematic review and meta-analysis of the evidence for community-based HIV testing on men's engagement in the HIV care cascade

OBJECTIVE

Men with HIV are less likely than women to know their status, be on antiretroviral therapy, and be virally suppressed. This review examined men's community-based HIV testing services (CB-HTS) outcomes.

DESIGN

Systematic review and meta-analysis.

METHODS

We searched seven databases and conference abstracts through July 2018. We estimated pooled proportions and/or risk ratios (for meta-analyses) for each outcome using random effects models.

RESULTS

188 studies met inclusion criteria. Common testing models included targeted outreach (e.g. mobile testing), home-based testing, and testing at stand-alone community sites. Across 25 studies reporting uptake, 81% (CI: 75-86%) of men offered testing accepted it. Uptake was higher among men reached through CB-HTS than facility-based HTS (RR = 1.39; CI: 1.13-1.71). Over 69% (CI: 64-71%) of those tested through CB-HTS were men, across 184 studies. Across studies reporting new HIV-positivity among men (n = 18), 96% were newly diagnosed (CI: 77-100%). Across studies reporting linkage to HIV care (n = 8), 70% (CI: 36-103%) of men were linked to care. Across 57 studies reporting sex-disaggregated data for CB-HTS conducted among key populations, men's uptake was high (80%; CI: 70-88%) and nearly all were newly diagnosed and linked to care (95%; CI: 94-100%; and 94%; CI: 88-100%, respectively).

CONCLUSION

CB-HTS is an important strategy for reaching undiagnosed men with HIV from the general population and key population groups, particularly using targeted outreach models. When compared to facility-based HIV testing services, men tested through CB-HTS are more likely to uptake testing, and nearly all men who tested positive through CB-HTS were newly diagnosed. Linkage to care may be a challenge following CB-HTS, and greater efforts and research are needed to effectively implement testing strategies that facilitate rapid ART initiation and linkage to prevention services.

A Systematic Review of HIV Testing Implementation Strategies in Sub-Saharan African Countries

HIV/AIDS remains a looming presence in public health across the world, particularly in Sub-Saharan Africa. The HIV Care Cascade hinges on testing and knowledge of HIV status. Though significant advances have been made in diagnosing people living with HIV (PLHIV), limitations in understanding which strategies are best suited to certain regions or populations have contributed to the uneven distribution in the success of various HIV testing strategies. Here, we present a conceptual framework that outlines effective HIV testing strategies for four target groups. This framework is based on a systematic literature review of articles published from January 1st, 2008, to December 31st, 2019. The effectiveness of HIV testing strategies depends on various factors including the setting, type of test and service providers. Multiple strategies are needed to reach the UNAIDS target of 95% of individuals knowing their HIV status. Expansion of community-based approaches, self-testing and HIV testing services in antenatal care will further improve the state of HIV testing in Sub-Saharan Africa.

Community- and facility-based HIV testing interventions in northern Tanzania: Midterm results of Test & Treat Project

Test & Treat Project offers universal HIV testing and access to antiretroviral treatment in Northern Tanzania. The current cross-sectional study provides midterm results on HIV testing and counseling activities through community outreaches and facility-based services. A total 255,329 HIV tests were performed: 198,451 (77.7%) during testing campaigns in the villages, 12,592 (4.9%) during special events outreach and 44,286 (17.4%) in the health facilities. Females represented 53.8% (23,809) among those tested in the health facilities, while males were the majority in the community (54.4%, 114,835). Over one third of tests (n = 104,605, 41%) were performed among first-time testers. The overall HIV positivity rate was 1.2%, ranging from 0.7% in the community to 3.8% in the health facilities and decreased over time. Using a multivariable analysis, a positive test result was associated with age ≥ 50 years (PR 1.22, 95% CI 1.11 to 1.34), with female gender (PR 1.61, 95% CI 1.50 to 1.73), being tested in health facilities (PR 5.00, 95% CI 4.65 to 5.36) and for the first time (PR 1.86, 95% CI 1.73 to 2.00). The estimated proportion of PLHIV who knew their status of the project area increased by 28.6% (from 35.7% to 64.3%) and 11.1% (from 57.7% to 68.8%) in the project areas of Shinyanga and Simiyu regions respectively. Reaching the first UNAIDS 90 target by the end of this project seems possible. Future strategies should focus on improving PITC coverage, implementing more targeted testing modalities, together with current universal community-based approach.

Findings from a novel and scalable community-based HIV testing approach to reduce the time required to complete point-of-care HIV testing in South Africa

BACKGROUND

Mobile HIV testing approaches are a key to reaching the global targets of halting the HIV epidemic by 2030. Importantly, the number of clients reached through mobile HIV testing approaches, need to remain high to maintain the cost-effectiveness of these approaches. Advances in rapid in-vitro tests such as INSTI® HIV-1/HIV-2 (INSTI) which uses flow-through technologies, offer opportunities to reduce the HIV testing time to about one minute. Using data from a routine mobile HTS programme which piloted the use of the INSTI point-of-care (POC) test, we sought to estimate the effect of using a faster test on client testing volumes and the number of people identified to be living with HIV, in comparison with standard of care HIV rapid tests.

METHODS

In November 2019, one out of four mobile HTS teams operating in Ekurhuleni District (South Africa) was randomly selected to pilot the field use of INSTI-POC test as an HIV screening test (i.e., the intervention team). We compared the median number of clients tested for HIV and the number of HIV-positive clients by the intervention team with another mobile HTS team (matched on performance and area of operation) which used the standard of care (SOC) HIV screening test (i.e., SOC team).

RESULTS

From 19 to 20 December 2019, the intervention team tested 7,403 clients, and the SOC team tested 2,426 clients. The intervention team tested a median of 442 (IQR: 288-522) clients/day; SOC team tested a median of 97 (IQR: 40-187) clients/day (p<0.0001). The intervention team tested about 180 more males/day compared to the SOC team, and the median number of adolescents and young adults tested/day by the intervention team were almost four times the number tested by the SOC team. The intervention team identified a higher number of HIV-positive clients compared to the SOC team (142 vs. 88), although the proportion of HIV-positive clients was lower in the intervention team due to the higher number of clients tested.

CONCLUSIONS

This pilot programme provides evidence of high performance and high reach, for men and young people through the use of faster HIV rapid tests, by trained lay counsellors in mobile HTS units.

Mobile HIV testing in South Africa: maximizing yield through data-guided site selection

BACKGROUND

Mobile community HIV testing can effectively reach undiagnosed people living with HIV in southern Africa. Variable yield in HIV test positivity has been a challenge with high- and low-yield sites often being closely situated. We sought to test whether easy-to-identify, site-level characteristics were associated with HIV positivity yield in a routine mobile HIV testing program.

METHODS

We used routine testing program test data augmented with site-level characterization, either of the community or shopping site at which HIV testing was offered. Specifically, we described the local environment and interviewed key informants to gain additional information regarding the availability of HIV and other services in the locale.

RESULTS

We included 122 residential and 26 shopping sites with median HIV-positive test yields of 7.6% and 6.9%, respectively. The range for community sites was from 2 to 55% with high and low yields at geographically proximal sites. Factors related to lower income and marginalization, including informal housing and the absence of name-brand stores in shopping venues, were associated with higher HIV-positive testing yield.

CONCLUSIONS

Characterization of sites, particularly identifying factors related to marginalization, lack of services, and poverty, can aid in identifying sites with higher HIV-positive yield.

A plea of those who are affected most by HIV: The utterances by women who inject Nyaope residing in the City of Tshwane Municipality, Gauteng

Background

Nyaope injecting practice brought the field of Human Immunodeficiency Virus (HIV) prevention and Substance Use Disorder (SUD) together. It is complex and requires multidisciplinary approach. Women who use drugs face individual, social, and structural factors that fuel their vulnerability to contract HIV, and other blood-borne infections. Women Who Inject Drugs (WWID) are a subpopulation that is neglected from HIV prevention and SUD treatment interventions, and are hardly the subject of surveys. In order to fully address the HIV epidemic among WWID it is imperative that they become part of the process of finding solutions.

Aim

This study explored the strategies to curb HIV incidence among Women Who Inject Nyaope (WWIN), residing in City of Tshwane Municipality, Gauteng Province.

Setting

The research was conducted within COSUP. COSUP was considered more appropriate as it is a harm reduction based organisation.

Methods

The study utilised the qualitative research approach. Semi structured interviews were conducted with 24 women with a history of injecting Nyaope aged between 19 to 35 years. The data was analysed using thematic data analysis.

Results

Health intervention, economic intervention and educational intervention was stressed as key strategies to curb HIV among WWIN. Needle exchange programmes, condom distribution, PrEP, HIV Testing and Counselling, employment opportunities, support groups and awareness campaigns if implemented, can yield positive outcomes in curbing HIV among WWID.

Conclusion

Mechanisms to curb HIV among WWIN exist, and when implemented, they have the potential to address high HIV incidence among women who inject Nyaope.

Reaching underserved South Africans with integrated chronic disease screening and mobile HIV counselling and testing: A retrospective, longitudinal study conducted in Cape Town

BACKGROUND

Community-based, mobile HIV counselling and testing (HCT) and screening for non-communicable diseases (NCDs) may improve early diagnosis and referral for care in underserved populations. We evaluated HCT/NCD data and described population characteristics of those visiting a mobile clinic in high HIV disease burden settings in Cape Town, South Africa, between 2008 and 2016.

METHODS

Trained counsellors registered patients ≥12 years old at a mobile clinic, which offered HCT and blood pressure, diabetes (glucose testing) and obesity (body mass index) screening. A nurse referred patients who required HIV treatment or NCD care. Using multivariable logistic regression, we estimated correlates of new HIV diagnoses adjusting for gender, age and year.

RESULTS

Overall, 43,938 individuals (50% male; 29% <25 years; median age = 31 years) tested for HIV at the mobile clinic, where 27% of patients (66% of males, 34% of females) reported being debut HIV testers. Males not previously tested for HIV had higher rates of HIV positivity (11%) than females (7%). Over half (55%, n = 1,343) of those previously diagnosed HIV-positive had not initiated ART. More than one-quarter (26%) of patients screened positive for hypertension (males 28%, females 24%, p<0.001). Females were more likely overweight (25% vs 20%) or obese (43% vs 9%) and presented with more diabetes symptoms than males (8% vs 4%). Females (3%) reported more symptoms of STIs than males (1%). Reporting symptoms of sexually transmitted infections (aOR = 3.45, 95% CI = 2.84, 4.20), diabetes symptoms (aOR = 1.61, 95% 1.35, 1.92), and TB symptoms (aOR = 4.40, 95% CI = 3.85, 5.01) were associated with higher odds of a new HIV diagnosis after adjusting for covariates.

CONCLUSION

Findings demonstrate that mobile clinics providing integrated HCT and NCD screening may offer the opportunity of early diagnosis and referral for care for those who delay screening, including men living with HIV not previously tested.

Spatial pattern and associated factors of HIV testing and counselling among youths (15-24 years) in Ethiopia

BACKGROUND

HIV testing and counseling (HTC) services are key for HIV prevention, treatment, care, and support. Although the prevalence of HIV infection is high among adolescents and young adults, evidence suggests the utilization of HTC service among youth is very low in Ethiopia. Identifying factors and the geographic variation of HTC uptake is important to prioritize and design targeted prevention programs to increase its utilization and reduce HIV infection in hot spot areas.

METHODS

Data from the 2016 Ethiopian Demographic and Health Survey were used to analyze 10,781 youth aged 15-24 years. The spatial analysis was performed in ArcGIS 10.1. The Bernoulli model was used by applying Kulldorff methods using the SaTScan software to analyze the purely spatial clusters of HTC uptake. A multilevel logistic regression analysis was used to identify the associated individual and community-level factors of HTC uptake and estimate between community variance. All models were fitted in Stata version 14.0 and finally, the adjusted odds ratio (AOR) with a corresponding 95% confidence interval (CI) were reported.

RESULTS

In this study, the spatial patterns of HTC uptake were found to be non-random (Global Moran's I = 0.074, p value< 0.001). Forty-seven primary clusters were identified that were located in the entire Somali region with a relative likelihood of 1.50 and the Log-Likelihood Ratio of 135.57. Youth who were ever married (AOR = 4.65; 95% CI; 4.05, 5.34), those attended higher education (AOR = 3.97; 95% CI; 3.10,5.08), those from richest household (AOR = 1.86; 95% CI; 1.44, 2.39), aged 20-24 years (AOR = 2.25; 95% CI; 2.02,2.51), having compressive HIV related knowledge (AOR = 2.05; 95% CI; 1.75,2.41), and exposed to media (AOR = 1.38; 95% CI; 1.22,1.57) were positive association with HTC uptake. However, being male (AOR = 0.81; 95% CI; 0.73,0.91) and having high HIV related stigma (AOR = 0.53; 95% CI; 0.42,0.67) were negatively associated with HTC uptake. At the community-level, youth from communities with a high percentage of educated (AOR = 1.45; 95% CI; 1.17,1.80) were more likely to utilize HTC compared with those from communities with low percentages of educated.

CONCLUSION

The current study indicated differences in HTC uptake in the country. Both individual and community-level factors affected HTC uptake in Ethiopia. Multifaceted intervention approaches that consider individual and community factors are required to improve HTC uptake.

Mobile HIV Testing Through Social Networking Platforms: Comparative Study

Background

Improving HIV screening in key populations is a crucial strategy to achieve the goal of eliminating AIDS in 2030. Social networking platforms can be used to recruit high risk-taking men who have sex with men (MSM) to promote the delivery of voluntary counseling and testing (VCT) as mobile HIV testing. Therefore, client recruitment and availability of mobile HIV testing through social networking platforms requires further evaluation.

Objective

The aim of this study is to compare the effects of targeting high risk-taking MSM and HIV case finding between two mobile HIV testing recruitment approaches: through the traditional website-based approach and through social networking platforms.

Methods

A comparative study design and propensity score matching was applied. The traditional VCT model, that is, the control group, recruited MSM through a website, and a trained research assistant visited the walk-in testing station at a gay village on Friday and Saturday nights. The social networking VCT model, the experimental group, recruited MSM from social networking platforms by periodically reloading into and conducting web-based discussions on dating apps and Facebook. The participants then referred to others in their social networks via a popular messenger app in Taiwan. The test was conducted at a designated time and place during weekdays by a trained research assistant. Across both modes of contact, before the mobile HIV testing, participants needed to provide demographic characteristics and respond to a questionnaire about HIV risk-taking behaviors.

Results

We recruited 831 MSM over 6 months, with a completion rate of 8.56% (616/7200) in the traditional VCT model and 20.71% (215/1038) in the social networking VCT model. After propensity score matching, there were 215 MSM in each group (mean age 29.97, SD 7.61 years). The social networking model was more likely to reach MSM with HIV risk-taking behaviors, that is, those seeking sexual activity through social media, having multiple sexual partners and unprotected anal intercourse, having experience of recreational drug use, and never having or not regularly having an HIV test, compared with the traditional model. HIV positive rates (incidence rate ratio 3.40, 95% CI 1.089-10.584; P=.03) and clinic referral rates (incidence rate ratio 0.03, 95% CI 0.001-0.585; P=.006) were significantly higher among those in the social networking VCT model than in the traditional VCT model.

Conclusions

Through effective recruitment strategies on social networking platforms, the social networking VCT mode can be smoothly promoted, as compared with the traditional VCT model, to target high risk-taking MSM and increase testing outcomes.

Outcomes from a multimodal, at-scale community-based HIV counselling and testing programme in twelve high HIV burden districts in South Africa

INTRODUCTION

Facility-based HIV testing services (HTS) have been less acceptable and accessible by adolescents, men and key populations in South Africa. Community-based HIV counselling and testing (CBCT) modalities, including mobile unit and home-based testing, have been proposed to decrease barriers to HIV testing uptake. CBCT modalities and approaches may be differentially acceptable to men and women based on age. Implementation of multimodal CBCT services may improve HIV testing rates among adolescents and men, and support the roll-out of prevention services.

METHODS

A cross-sectional analysis was conducted using aggregate, routine programmatic data collected from 1 October 2015 through 31 March 2017 from a multimodal, at-scale CBCT programme implemented in 12 high-burden districts throughout South Africa. Data collection tools were aligned to reporting standards for the National Department of Health and donor requirements. HIV testing rates (i.e. number of tests performed per 100,000 population using South African census data) and testing proportions by modality were stratified by sex, age groups and heath districts. Descriptive statistics were performed using STATA 13.0.

RESULTS

Overall, 944,487 tests were performed during the 1.5-year testing period reported. More tests were conducted among females than males (53.6% vs. 46.4%). Overall, 8206 tests per 100,000 population (95% CI: 8190.2 to 8221.9) were performed; female-to-male (F:M) testing ratio was 1.11. Testing rates were highest among young women age 20 to 24 years (16,328.4; 95% CI: 16,237.9 to 16,419.1) and adolescent girls aged 15 to 19 years (12,817.0; 95% CI: 12,727.9 to 12,906.6). Home-based testing accounted for 61.3% of HIV tests, followed by near-home mobile unit testing (30.2%) and workplace mobile unit testing (4.7%). More women received HTS via home-based testing (F:M ratio = 1.29), whereas more men accessed work-place mobile testing (M:F ratio = 1.35). No sex differential was observed among those accessing near-home mobile testing (F:M ratio = 0.98).

CONCLUSIONS

Concurrent implementation of multiple, targeted CBCT modalities can reduce sex disparities in HIV testing in South Africa. Given the acceptability and accessibility of these CBCT services to adolescent girls and young women, evident from their high testing rates, leveraging community-based services delivery platforms to increase access to HIV prevention services, including pre-exposure prophylaxis (PrEP), should be considered.

Feasibility of implementing same-day antiretroviral therapy initiation during routine care in Ekurhuleni District, South Africa: Retention and viral load suppression

Background

Same-day initiation (SDI) of antiretroviral therapy (ART) has been advocated as an approach to increase linkage to care and overall ART initiation. Clinical trials have demonstrated impressive benefits. However, questions regarding patient preparedness and retention in care remain for routine implementation of this approach.

Objectives

In this study, we sought to describe SDI of ART during routine care delivery and compare time to ART initiation on longitudinal care outcomes.

Method

We performed a retrospective chart review of 100 consecutive individuals, newly diagnosed with HIV, from 10 health facilities across Ekurhuleni, from January to July 2017. Records were reviewed for a period of 1 year post-diagnosis. Abstracted data included demographics, time to ART initiation, clinic visits and laboratory test results (including viral load testing).

Results

A total of 993 patient records were reviewed, of which 826 were included in the analysis. The majority of patients (752, 91%) had ART initiation recorded, of which 654 (79%) had ART initiated within 30 days, and 224 (27%) had SDI. Uptake of SDI of ART was higher among women (36% vs. 10.4%; p < 0.001) and in younger patients (33.7% in those < 29 years; p < 0.01). Retention in care at 6 months was achieved in 477 (58%) patients. Of those with 6-month viral loads, 350/430 (73%) had a viral load < 400 c/m. Retention in care and viral suppression were similar among those with SDI of ART and later ART initiation.

Conclusion

Same-day initiation of ART was successfully delivered with similar retention and viral load outcomes as subsequent initiation, providing re-assurance for scale-up of this strategy in routine care.

Utilization rate and factors influencing the use of HIV counseling and testing services among young females: a community-based study from Nigeria

Objectives This study aims to explore the utilization rate and factors influencing the use of HCT services among young females in Ikorodu, Lagos State, Nigeria. Methods This study was a descriptive cross-sectional survey of 404 females, aged 15-24 years, residing in Ikorodu, Nigeria. Study tool was a questionnaire. Collected data was analyzed using the SPSS version 16 software. Results The mean age (±SD) of the respondents was 19.3 (±2.6) years and 90.1% were single. Only 148 (36.6%) respondents had ever utilized the HCT service, of which only 40.5% of them were adolescents. Amongst those that had ever utilized HCT services (n=148), only 60.1% of them did so within 12 months prior to the study while only 33.8% of them initiated the demand for testing themselves. According to the respondents, the top two barriers to the utilization of HCT services were: fear of discrimination (82.9%); and fear of unavailability of access to treatment (68.0%), while the top two factors that facilitates its use were: the adoption of counseling-before-testing approach in the HCT service centers (85.9%); and peoples' need for HIV status declaration prior to getting a job employment/marriage partner (85.1%). Conclusions The study shows that utilization of HCT service remains low among the respondents. There is an urgent need to encourage the utilization of HCT services among young females in Ikorodu, Nigeria.

Factors Affecting Voluntary HIV Testing Among General Adult Population: A Cross-Sectional Study in Sarawak, Malaysia

Objective: Voluntary HIV testing is one of the key strategies in the HIV/AIDS prevention and control program. New National Strategic Plan for 2016-2030 in Malaysia, adapt three zeros viz. 'zero new infections of HIV/AIDS, zero discrimination and zero AIDS-related deaths'. This study aimed to determine the predictors of voluntary HIV testing in Sarawak. Materials and methods: A cross-sectional study was conducted with a total of 900 respondents (450 males and 450 females) from the state of Sarawak, aged 18 years and above, who were selected by gender-stratified multistage cluster sampling. Data were obtained by face-to-face interview using a pretested questionnaire. Binary logistic regression analysis was done to determine the potential predictors for voluntary HIV testing. Results: The prevalence of HIV testing was higher among female respondents (26%) compared to male respondents (14.2%), and the difference was statistically significant (p < 0.001). Binary logistic regression analysis revealed that household income more than MYR 1501 (p = 0.009), not living with a partner (p < 0.001) and discussion on HIV/AIDS (p = 0.019) appeared to be predictors for the male respondents, while, ethnicity was statistically significant for female respondents (p < 0.001). Conclusion: The utilisation of HIV testing was low in both males and females. Thus, the finding of this study could be considered when designing HIV education and screening program in Sarawak.

Who are the missing men? Characterising men who never tested for HIV from population-based surveys in six sub-Saharan African countries

INTRODUCTION

We sought to characterize men who had never tested for HIV, understand factors associated with not testing, and measure survey HIV test uptake among never testers. We analysed nationally representative Demographic and Health Surveys of six African countries from 2013 to 2016: Ethiopia, Malawi, Zimbabwe, Rwanda, Lesotho and Zambia.

METHODS

Eligible men were household residents or overnight visitors aged 15 to 59 years. We analysed questionnaire responses on HIV testing, known behavioural risk factors, and corresponding HIV laboratory results. We used survey-weighted logistic regression to identify factors associated with never testing for HIV.

RESULTS

Approximately double the proportion of men had never tested for HIV compared to women (Malawi: 30% vs. 17%, p < 0.0001; Zimbabwe: 35% vs. 19%, p < 0.0001; Lesotho: 34% vs. 15%, p < 0.0001; Zambia: 36% vs. 20%, p < 0.0001); although, less of a differential existed in Ethiopia (54% vs. 56%, p = 0.12) and Rwanda (19% vs. 14%, p < 0.0001). When offered a test during the survey, 85% to 99% of sexually active men who reported never previously testing, accepted testing. HIV positivity ranged from <0.05% to 14% for never tested men. After adjusting for age, factors associated with never having tested for HIV were never being married (aOR range: 1.46 to 10.39), not having children (aOR: 1.36 to 3.59) and lower education (less than primary education aOR: 2.77 to 5.59).

CONCLUSIONS

Although higher proportions of men than women had never tested for HIV, 85% to 99% of men did accept a test when offered. Finding opportunities to offer HIV testing to single men without children, older men who have never tested, and those disadvantaged with less schooling and employment, alongside other facility and community-based services, will be important in identifying those living with undiagnosed HIV and improving men's health.

Methods, outcomes, and costs of a 2.5 year comprehensive facility-and community-based HIV testing intervention in Bukoba Municipal Council, Tanzania, 2014-2017

To diagnose ≥90% HIV-infected residents (diagnostic coverage), the Bukoba Combination Prevention Evaluation (BCPE) implemented provider-initiated (PITC), home- (HBHTC), and venue-based (VBHTC) HIV testing and counseling (HTC) intervention in Bukoba Municipal Council, a mixed urban and rural lake zone community of 150,000 residents in Tanzania. This paper describes the methods, outcomes, and incremental costs of these HTC interventions. PITC was implemented in outpatient department clinics in all eight public and three faith-based health facilities. In clinics, lay counselors routinely screened and referred eligible patients for HIV testing conducted by HTC-dedicated healthcare workers. In all 14 wards, community teams offered HTC to eligible persons encountered at 31,293 home visits and at 79 male- and youth-frequented venues. HTC was recommended for persons who were not in HIV care or had not tested in the prior 90 days. BCPE conducted 133,695 HIV tests during the 2.5 year intervention (PITC: 88,813, 66%; HBHTC: 27,407, 21%; VBHTC: 17,475, 13%). Compared with other strategies, PITC conducted proportionally more tests among females (65%), and VBHTC conducted proportionally more tests among males (69%) and young-adults aged 15-24 years (42%). Of 5,550 (4.2% of all tests) HIV-positive tests, 4,143 (75%) clients were newly HIV diagnosed, including 1,583 males and 881 young adults aged 15-24 years. Of HIV tests conducted 3.7%, 1.8%, and 2.1% of PITC, HBHTC, and VBHTC clients, respectively, were newly HIV diagnosed; PITC accounted for 79% of all new diagnoses. Cost per test (per new diagnosis) was $4.55 ($123.66), $6.45 ($354.44), and $7.98 ($372.67) for PITC, HBHTC, and VBHTC, respectively. In a task-shifting analysis in which lay counselors replaced healthcare workers, estimated costs per test (per new diagnosis) would have been $3.06 ($83.15), $ 4.81 ($264.04), and $5.45 ($254.52), for PITC, HBHTC, and VBHTC, respectively. BCPE models reached different target groups, including men and young adults, two groups with consistently low coverage. Implementation of multiple models is likely necessary to achieve ≥90% diagnostic coverage.

Linkage to care and antiretroviral therapy initiation by testing modality among individuals newly diagnosed with HIV in Tanzania, 2014-2017

OBJECTIVE

To measure linkage to care and antiretroviral therapy (ART) initiation among newly diagnosed individuals with HIV in a rural Tanzanian community.

METHODS

We included all new HIV diagnoses of adults made between 2014 and 2017 during community- or facility-based HIV testing and counselling (HTC) in a rural ward in northwest Tanzania. Community-based HTC included population-level HIV serological testing (sero-survey), and facility-based HTC included a stationary, voluntary HTC clinic (VCT) and an antenatal clinic (ANC) offering provider-initiated HTC (ANC-PITC). Cox regression models were used to compare linkage to care rates by testing modality and identify associated factors. Among those in care, we compared initial CD4 cell counts and ART initiation rates by testing modality.

RESULTS

A total of 411 adults were newly diagnosed, of whom 10% (27/265 sero-survey), 18% (3/14 facility-based ANC-PITC) and 53% (68/129 facility-based VCT) linked to care within 90 days. Individuals diagnosed using facility-based VCT were seven times (95% CI: 4.5-11.0) more likely to link to care than those diagnosed in the sero-survey. We found no difference in linkage rates between those diagnosed using facility-based ANC-PITC and sero-survey (P = 0.26). Among individuals in care, 63% of those in the sero-survey had an initial CD4 count >350 cells/mm³ vs. 29% of those using facility-based VCT (P = 0.02). The proportion who initiated ART within 1 year of linkage to care was similar for both groups (94% sero-survey vs. 85% facility-based VCT; P = 0.16).

CONCLUSIONS

Community-based sero-surveys are important for earlier diagnosis of HIV-positive individuals; however, interventions are essential to facilitate linkage to care.

Nurturing the Continuum of HIV Testing, Treatment and Prevention Matrix Cascade in Reducing HIV Transmission

Background

Despite the shift in antiretroviral therapy (ARVs) eligibility cascade from CD4 ≤ 200 to CD4 ≤ 350 to CD4 ≤ 500 mm³, HIV related morbidity and mortality continue to escalate annually, as do HIV infections. The new paradigm of treatment for all HIV positives individual irrespective of CD4 count may significantly reduce HIV and related illnesses. The author assumes that all HIV infected partners should be eligible for HIV treatment and care, irrespective of CD4 count. A second assumption is that high risk HIV negative partners have free access to continuum of HIV pre-exposure prophylaxis (PrEP), post exposure prophylaxis (PEP) and other prevention packages.

Methods

A literature review search was used to extract evidence-based ARVs-HIV treatment and prevention interventions among HIV positives and high risk partners respectively. Only articles published in English and indexed in journal nuclei were used for the study. The information was used to nurture understanding of HIV treatment and prevention approaches as well as HIV incidence multiplier effect among HIV serodiscordant partners. The imputed HIV incident reference was assumed at 1.2 per 100 person-years (2). This was based on the imputation that retention in care, adherence and other predetermined factors are functions of an effective health care delivery system.

Result

The model showed a reduced HIV transmission from 1.2 per 100 person-years to 1.032 per 100 person-years in 6 months. The average threshold period of HIV suppressed partners on ARVs to an undetectable level. The combined multiplier protective-effect probability of transmitting HIV from HIV positive partners on ARVs-suppressed viremic load to HIV negative partners on PrEP/PEP-prevention was detected at 86%

Conclusion

The model showed a significant reduction in HIV incidence. Placing serodiscordant sexual partners in HIV treatment and prevention plays a significant role in reducing and controlling HIV infection. Therefore, the policy of enrolling all HIV positives irrespective of CD4 count on ARVs and high risk partners on prevention if adopted and sustained may underpin reduction and control of HIV genotype and HIV related morbidity, mortality and opportunistic infections.

Socio-demographic characteristics and the utilization of HIV testing and counselling services among the key populations at the Bhutanese Refugees Camps in Eastern Nepal

Objectives

This cross-sectional study was conducted to describe the socio-demographic characteristics, assess the utilization of HIV testing and counselling services, and to explore the reasons for the non-utilization of HIV testing and counselling services among the key populations at the Bhutanese refugee camps in eastern Nepal.

Results

The HIV testing and counselling services are utilized by less than a third (29%) of the key population among the Bhutanese Refugees. The prime source of information about the HIV testing and counselling sites has been health workers followed by peer/outreach educators and neighbors. Common self-reported barriers for utilization of HIV testing and counselling services by the Bhutanese refugees were self-perceived stigma about HIV, the fear of being discriminated and the lack of knowledge about HIV testing and counselling services. There is a need to analyze the gap between availability and utilization through more qualitative approaches in order to identify interventions to increase the uptake of the HIV testing and counselling services.

Factors associated with linkage to HIV care and TB treatment at community-based HIV testing services in Cape Town, South Africa

BACKGROUND

Diagnosing HIV and/or TB is not sufficient; linkage to care and treatment is conditional to reduce the burden of disease. This study aimed to determine factors associated with linkage to HIV care and TB treatment at community-based services in Cape Town, South Africa.

METHODS

This retrospective cohort study utilized routinely collected data from clients who utilized stand-alone (fixed site not attached to a health facility) and mobile HIV testing services in eight communities in the City of Cape Town Metropolitan district, between January 2008 and June 2012. Clients were included in the analysis if they were ≥12 years and had a known HIV status. Generalized estimating equations (GEE) logistic regression models were used to assess the association between determinants (sex, age, HIV testing service and co-infection status) and self-reported linkage to HIV care and/or TB treatment.

RESULTS

Linkage to HIV care was 3 738/5 929 (63.1%). Linkage to HIV care was associated with the type of HIV testing service. Clients diagnosed with HIV at mobile services had a significantly reduced odds of linking to HIV care (aOR 0.7 (CI 95%: 0.6-0.8), p<0.001. Linkage to TB treatment was 210/275 (76.4%). Linkage to TB treatment was not associated with sex and service type, but was associated with age. Clients in older age groups were less likely to link to TB treatment compared to clients in the age group 12-24 years (all, p-value<0.05).

CONCLUSION

A large proportion of clients diagnosed with HIV at mobile services did not link to care. Almost a quarter of clients diagnosed with TB did not link to treatment. Integrated community-based HIV and TB testing services are efficient in diagnosing HIV and TB, but strategies to improve linkage to care are required to control these epidemics.

Acceptability of HIV Self-Testing in Sub-Saharan Africa: Scoping Study

Several HIV testing models have been implemented in sub-Saharan Africa (SSA) to improve access to HIV testing, but uptake remains poor. HIV Self-Testing (HIVST) is now available, and may serve to overcome barriers of current testing models which include stigma, discrimination and non-confidential testing environments. A scoping study was conducted to provide an overview of the current literature in SSA, as well as identify future research needs to scale-up HIVST and increase HIV testing uptake. The outcome of the review indicated only 11 reported studies to date, showing variable acceptability (22.3-94%) of HIVST, with acceptability of HIVST higher among men than women in SSA. We conclude that research around HIVST in SSA is still in its infancy, and further implementation research and interventions are required to improve acceptability of HIVST among diverse study populations, failing which policy adoption and scale-up may be hindered.

Access to human immunodeficiency virus testing services in Cape Town, South Africa: a user perspective

Objective: To compare the availability, affordability and acceptability of two non-governmental organisation (NGO) led human immunodeficiency virus (HIV) testing service (HTS) modalities (mobile and stand-alone) with HTS at a public primary health care facility. Methods: Adult participants who self-referred for HIV testing were enrolled as they exited the HTS modalities. Data collection using an electronic questionnaire took place between November 2014 and February 2015. Logistic regression analysis was used to assess differences in the participants' demographic characteristics and the availability, affordability and acceptability of HTS between modalities. Results: There were 130 participants included in the study. Irrespective of modality, most participants walked to the service provider, had a travel time of <30 min and reported no costs. Participants were less likely to report waiting times of ⩾30 min compared to <15 min at the mobile modality compared to the public facility (aOR < 0.001, 95%CI < 0.001-0.03). Conclusion: Irrespective of modality, HIV testing services were available and affordable in our study. Waiting times were significantly higher at the public facility compared to the NGO modalities. As South Africa moves toward achieving the first UNAIDS target, it is essential not only to make HTS available and affordable, but also to ensure that these services are acceptable, especially to those who have never been tested before.

Strategies to Accelerate HIV Care and Antiretroviral Therapy Initiation After HIV Diagnosis: A Randomized Trial

OBJECTIVE

Determine the effectiveness of strategies to increase linkage to care after testing HIV positive at mobile HIV testing in South Africa.

DESIGN

Unmasked randomized controlled trial.

METHODS

Recruitment of adults testing HIV positive and not currently in HIV care occurred at 7 mobile HIV counseling and testing units in urban, periurban, and rural South Africa with those consenting randomized 1:1:1:1 into 1 of 4 arms. Three strategies were compared with standard of care (SOC): point-of-care CD4 count testing (POC CD4), POC CD4 plus longitudinal strengths-based counseling (care facilitation; CF), and POC CD4 plus transport reimbursement (transport). Participants were followed up telephonically and through clinic records and analyzed with an intention-to-treat analysis.

RESULTS

From March 2013 to October 2014, 2558 participants were enrolled, of whom 160 were excluded postrandomization. Compared with the SOC arm where 298 (50%) reported having entered care, linkage to care was 319 (52%) for POC CD4, hazard ratio (HR) 1.0 [95% confidence interval (CI): 0.89 to 1.2, P = 0.6]; 331 (55%) for CF, HR: 1.1 (95% CI: 0.84 to 1.3, P = 0.2); and 291 (49%) for transport, HR 0.97 (95% CI: 0.83 to 1.1, P = 0.7). Linkage to care verified with clinical records that occurred for 172 (29%) in the SOC arm; 187 (31%) in the POC CD4 arm, HR: 1.0 (95% CI: 0.86 to 1.3, P = 0.6); 225 (38%) in the CF arm, HR: 1.4 (95% CI: 1.1 to 1.7, P = 0.001); and 180 (31%) in the transport arm, HR: 1.1 (95% CI: 0.88 to 1.3, P = 0.5).

CONCLUSIONS

CF improved verified linkage to care from 29% to 38%.

Mitigating intimate partner violence among South African women testing HIV positive during mobile counseling and testing

South African women continue to suffer disproportionately from the interlinked epidemics of HIV and intimate partner violence (IPV). Effective strategies are needed to mitigate HIV-related IPV, which often creates barriers to successful engagement along the HIV continuum of care. More information is needed on how IPV impacts women's safety following mobile HCT diagnosis, and the HIV IPV Risk Assessment & Safety-planning (HIRS) protocol was developed to address several related gaps in knowledge. The sample included 255 black South African women experiencing IPV and testing HIV+ during mobile HCT in Gauteng province. Outcomes were compared between a standard of care (SOC) group and an Experimental group with two dosage levels (D1, D2). Of the total sample and in the last year, 99.2% had experienced non-violent control, 40.7% physical abuse, 44.8% sexual abuse, and 67.3% physical or sexual abuse. There were no significant differences in pre/post safety scores, or for satisfaction or acceptability items. The overall linkage rate was 45.8% (M = 12.97 days), and the Experimental group had more links to care in certain age groups-the highest in those aged ≤23 years in D1 (70%). The lowest linkage rate was for those aged 33-43 years in the SOC (22.2%). Almost two thirds of participants reported using the safety plan (61.9%), with 80% reporting it was helpful, and 80% using ≥1 safety strategy. The Experimental group reported significantly less violence upon partner notification of serostatus, but all groups felt significantly less safe getting to medical appointments by post-test. Overall, the study indicates the HIRS protocol is safe and helpful, brief to administer, and may mitigate violence during partner notification of serostatus, but further investigation is needed before implementing it as a standard of care.

Mobile Medical Units—Can They Improve the Quality of Health Services in Developing Countries?

Purpose:

Mobile Medical Units, developed under health strategies of many developing countries, are now emerging as a newer approach on mass scale for improving access to health care services in underserved rural areas. Therefore, it is important to study the role of Mobile Medical Units in improving the quality of health services in developing countries.

Methodology:

An extensive literature search was performed with databases such as MEDLINE, PsycINFO, Biomed Central, Web of Science, Cochrane Library and Worldcat library, using a filter for last 25 years. Google was used to further refine the search. Studies of developed world, emergency role of Mobile Medical Units and unpublished items were excluded from this review.

Findings:

The literature revealed that Mobile Medical Units is still a nascent strategy to deliver health care. The available data regarding effect of Mobile Medical Units on quality of health care are very inconsistent and scanty. Better strategies, not only during the implementation period but also both pre- and post-launch are required for improving effectiveness and sustainability of Mobile Medical Units.

Practical implications:

This review summarizes the body of evidence which can assist the scientists and policymakers while evaluating the effectiveness of mobile medical units in health care delivery.

Research implications:

The present study gives a direction for future research mainly in three areas: assessing the stakeholder satisfaction, studying the constraints and critical success factors while implementing the services of Mobile Medical Units.

Value:

Since it is the first review of its kind, it will not only fill the gap in published literature but also provide a direction to the researchers for taking up in-depth studies in future which could improve the quality of health services in developing countries.

Linkage to HIV care after home-based HIV counselling and testing in sub-Saharan Africa: a systematic review

BACKGROUND

Home-based HIV counselling and testing (HBHCT) has the potential to increase HIV testing uptake in sub-Saharan Africa (SSA), but data on linkage to HIV care after HBHCT are scarce. We conducted a systematic review of linkage to care after HBHCT in SSA.

METHODS

Five databases were searched for studies published between 1st January 2000 and 19th August 2016 that reported on linkage to care among adults newly identified with HIV infection through HBHCT. Eligible studies were reviewed, assessed for risk of bias and findings summarised using the PRISMA guidelines.

RESULTS

A total of 14 studies from six countries met the eligibility criteria; nine used specific strategies (point-of-care CD4 count testing, follow-up counselling, provision of transport funds to clinic and counsellor facilitation of HIV clinic visit) in addition to routine referral to facilitate linkage to care. Time intervals for ascertaining linkage ranged from 1 week to 12 months post-HBHCT. Linkage ranged from 8.2% [95% confidence interval (CI), 6.8-9.8%] to 99.1% (95% CI, 96.9-99.9%). Linkage was generally lower (<33%) if HBHCT was followed by referral only, and higher (>80%) if additional strategies were used. Only one study assessed linkage by means of a randomised trial. Five studies had data on cotrimoxazole (CTX) prophylaxis and 12 on ART eligibility and initiation. CTX uptake among those eligible ranged from 0% to 100%. The proportion of persons eligible for ART ranged from 16.5% (95% CI, 12.1-21.8) to 77.8% (95% CI, 40.0-97.2). ART initiation among those eligible ranged from 14.3% (95% CI, 0.36-57.9%) to 94.9% (95% CI, 91.3-97.4%). Additional linkage strategies, whilst seeming to increase linkage, were not associated with higher uptake of CTX and/or ART. Most of the studies were susceptible to risk of outcome ascertainment bias. A pooled analysis was not performed because of heterogeneity across studies with regard to design, setting and the key variable definitions.

CONCLUSION

Only few studies from SSA investigated linkage to care among adults newly diagnosed with HIV through HBHCT. Linkage was often low after routine referral but higher if additional interventions were used to facilitate it. The effectiveness of linkage strategies should be confirmed through randomised controlled trials.

Shout-It-Now: A Mobile HCT Model Employing Technology and Edutainment in South Africa

BACKGROUND

Mobile HIV counseling and testing (HCT) has been effective in reaching men, women, and adolescents in South Africa. However, there is limited understanding of effective mobile HCT programs utilizing tools like technology and edutainment to increase HIV counseling and testing rates. The authors examine data from the Shout-It-Now (S-N) program that uses such tools in South Africa.

METHODS

The S-N program utilizes various forms of technology and ongoing telephonic counseling within a 6-step program of HIV testing and linkage-to-care support, and program data were analyzed over an 18-month period. Data were analyzed from women, men, and adolescent program participants. Summative statistics was conducted on participant registration, HIV risk assessment, and HIV testing profiles. HIV prevalence were estimated along with the related 95% confidence intervals using the Clopper-Pearson method.

RESULTS

Over an 18-month period, there were 72 220 program participants with high representation of men, women, and adolescents and 40% of the participants being men at each site. There were 3343 participants who tested HIV positive, and a higher proportion of women tested positive.

DISCUSSION

Integrating technology, quality assurance measures, and edutainment with mobile HCT has the potential to increase the number of those who test within communities. Research is needed to understand the effectiveness of this model in facilitating regular testing and linkage to care.

Looking for sufficient change: Evaluation of counsellor training for STI syndromic management in India

In India, public health care of Sexually Transmitted Infections is delivered through Designated STI/RTI Clinics (DSRCs) using syndromic management. This paper describes efforts, over three years, to improve in-service training for counsellors positioned at DSRCs-using a data approach. The programme managers realised, through rigorous monitoring of initial induction training reports that, while knowledge and attitudes of most trainees had improved as evident from t-tests, at least one-quarter scored worse on post-training assessments (n=859). Therefore, they undertook a survey using a competency approach to diagnose what critical competencies are influenced through training: counselling skills, risk reduction suggestions, labelling male and female anatomy, record-keeping and STI patient education (n=132). Survey results demonstrated that trainees failed to pass a two-thirds cutoff score in most competencies. These findings led the programme managers to modify training and implement tighter quality measures. In the second round of training - refresher training - outcomes on competency assessments before and after training showed more acceptable performance (n=833). The paper describes how programme managers, after an acceptance of such initial short-comings, developed customized assessments when literature provided limited guidance and how they worked to achieve change that was acceptable for programme needs.

Factors associated with changes in uptake of HIV testing among young women (aged 15-24) in Tanzania from 2003 to 2012

Background

This study explored the factors associated with changes in HIV testing uptake among young women in Tanzania, based on an analysis of data from the 2003–2004 Tanzania HIV/AIDS Indicator Survey, and the 2007–2008 and 2011–2012 Tanzania HIV/AIDS and Malaria Indicator Surveys.

Methods

The study population consisted of young women aged 15–24 years at the time of the survey. Multivariate decomposition analysis was used to assess factors associated with changes in HIV testing uptake between the 2003–2004 and 2007–2008 surveys, and between the 2007–2008 and 2011–2012 surveys.

Results

HIV testing uptake among the study population was 7 % in 2003–2004, 31 % in 2007–2008 and 40 % in 2011–2012. The time period of the survey had a substantial effect on the uptake of HIV testing independent of other covariates. The characteristics that were significantly associated with a higher chance of HIV testing uptake across the surveys were age (20–24), education level (primary and secondary), ever being married, having at least one lifetime sexual partner, having a sexually transmitted infection or associated symptoms, and receiving antenatal care.

Conclusions

Changes in the study participants’ characteristics in the 2003–2004 survey compared with the 2007–2008 survey were associated with a decrease in HIV testing uptake. Comparing the 2007–2008 survey with the 2011–2012 survey shows that the changes in the participants’ characteristics contributed to 22 % of the changes in HIV testing uptake, while 78 % of the changes were attributed to coefficients.

Household HIV Testing Uptake among Contacts of TB Patients in South Africa

BACKGROUND

In high HIV prevalence settings, offering HIV testing may be a reasonable part of contact tracing of index tuberculosis (TB) patients. We evaluated the uptake of HIV counselling and testing (HCT) among household contacts of index TB patients and the proportion of newly diagnosed HIV-infected persons linked into care as part of a household TB contact tracing study.

METHODS

We recruited index TB patients at public health clinics in two South African provinces to obtain consent for household contact tracing. During scheduled household visits we offered TB symptom screening to all household members and HCT to individuals ≥14years of age. Factors associated with HCT uptake were investigated using a random effects logistic regression model.

RESULTS & DISCUSSION

Out of 1,887 listed household members ≥14 years old, 984 (52%) were available during a household visit and offered HCT of which 108 (11%) self-reported being HIV infected and did not undergo HCT. Of the remaining 876, a total of 304 agreed to HCT (35%); 26 (8.6%) were newly diagnosed as HIV positive. In multivariable analysis, factors associated with uptake of HCT were prior testing (odds ratio 1.6; 95% confidence interval [CI]: 1.1-2.3) and another member in the household testing (odds ratio 2.4; 95% CI: 1.7-3.4). Within 3 months of testing HIV-positive, 35% reported initiating HIV care.

CONCLUSION

HCT as a component of household TB contact tracing reached individuals without prior HIV testing, however uptake of HIV testing was poor. Strategies to improve HIV testing in household contacts should be evaluated.

Changes in self-reported HIV testing during South Africa's 2010/2011 national testing campaign: gains and shortfalls

Objectives

HIV counselling and testing is critical to HIV prevention and treatment efforts. Mass campaigns may be an effective strategy to increase HIV testing in countries with generalized HIV epidemics. We assessed the self-reported uptake of HIV testing among individuals who had never previously tested for HIV, particularly those in high-risk populations, during the period of a national, multisector testing campaign in South Africa (April 2010 and June 2011).

Design

This study was a prospective cohort study.

Methods

We analyzed data from two waves (2010/2011, n=16,893; 2012, n=18,707) of the National Income Dynamics Study, a nationally representative cohort that enabled prospective identification of first-time testers. We quantified the number of adults (15 years and older) testing for the first time nationally. To assess whether the campaign reached previously underserved populations, we examined changes in HIV testing coverage by age, gender, race and province sub-groups. We also estimated multivariable logistic regression models to identify socio-economic and demographic predictors of first-time testing.

Results

Overall, the proportion of adults ever tested for HIV increased from 43.7% (95% confidence interval (CI): 41.48, 45.96) to 65.2% (95% CI: 63.28, 67.10) over the study period, with approximately 7.6 million (95% CI: 6,387,910; 8,782,986) first-time testers. Among black South Africans, the country's highest HIV prevalence sub-group, HIV testing coverage improved among poorer and healthier individuals, thus reducing gradients in testing by wealth and health. In contrast, HIV testing coverage remained lower for men, younger individuals and the less educated, indicating persistent if not widening disparities by gender, age and education. Large geographic disparities in coverage also remained as of 2012.

Conclusions

Mass provision of HIV testing services can be effective in increasing population coverage of HIV testing. The geographic and socio-economic disparities in programme impacts can help guide best practices for future efforts. These efforts should focus on hard-to-reach populations, including men and less-educated individuals.

Systematic review and meta-analysis of community and facility-based HIV testing to address linkage to care gaps in sub-Saharan Africa

HIV testing and counselling is the first crucial step for linkage to HIV treatment and prevention. However, despite high HIV burden in sub-Saharan Africa, testing coverage is low, particularly among young adults and men. Community-based HIV testing and counselling (testing outside of health facilities) has the potential to reduce coverage gaps, but the relative impact of different modalities is not well assessed. We conducted a systematic review of HIV testing modalities, characterizing community (home, mobile, index, key populations, campaign, workplace and self-testing) and facility approaches by population reached, HIV positivity, CD4 count at diagnosis and linkage. Of 2,520 abstracts screened, 126 met eligibility criteria. Community HIV testing and counselling had high coverage and uptake and identified HIV-positive people at higher CD4 counts than facility testing. Mobile HIV testing reached the highest proportion of men of all modalities examined (50%, 95% confidence interval (CI) = 47-54%) and home with self-testing reached the highest proportion of young adults (66%, 95% CI = 65-67%). Few studies evaluated HIV testing for key populations (commercial sex workers and men who have sex with men), but these interventions yielded high HIV positivity (38%, 95% CI = 19-62%) combined with the highest proportion of first-time testers (78%, 95% CI = 63-88%), indicating service gaps. Community testing with facilitated linkage (for example, counsellor follow-up to support linkage) achieved high linkage to care (95%, 95% CI = 87-98%) and antiretroviral initiation (75%, 95% CI = 68-82%). Expanding home and mobile testing, self-testing and outreach to key populations with facilitated linkage can increase the proportion of men, young adults and high-risk individuals linked to HIV treatment and prevention, and decrease HIV burden.

Partner Notification for Reduction of HIV-1 Transmission and Related Costs among Men Who Have Sex with Men: A Mathematical Modeling Study

Background

Earlier antiretroviral treatment initiation prevents new HIV infections. A key problem in HIV prevention and care is the high number of patients diagnosed late, as these undiagnosed patients can continue forward HIV transmission. We modeled the impact on the Dutch men-who-have-sex-with-men (MSM) HIV epidemic and cost-effectiveness of an existing partner notification process for earlier identification of HIV-infected individuals to reduce HIV transmission.

Methods

Reduction in new infections and cost-effectiveness ratios were obtained for the use of partner notification to identify 5% of all new diagnoses (Scenario 1) and 20% of all new diagnoses (Scenario 2), versus no partner notification. Costs and quality adjusted life years (QALYs) were assigned to each disease state and calculated over 5 year increments for a 20 year period.

Results

Partner notification is predicted to avert 18–69 infections (interquartile range [IQR] 13–24; 51–93) over the course of 5 years countrywide to 221–830 (IQR 140–299; 530–1,127) over 20 years for Scenario 1 and 2 respectively. Partner notification was considered cost-effective in the short term, with increasing cost-effectiveness over time: from €41,476 -€41, 736 (IQR €40,529-€42,147; €40,791-€42,397) to €5,773 -€5,887 (€5,134-€7,196; €5,411-€6,552) per QALY gained over a 5 and 20 year period, respectively. The full monetary benefits of partner notification by preventing new HIV infections become more apparent over time.

Conclusions

Partner notification will not lead to the end of the HIV epidemic, but will prevent new infections and be increasingly cost-effectiveness over time.

Uptake and yield of HIV testing and counselling among children and adolescents in sub-Saharan Africa: a systematic review

INTRODUCTION

In recent years children and adolescents have emerged as a priority for HIV prevention and care services. We conducted a systematic review to investigate the acceptability, yield and prevalence of HIV testing and counselling (HTC) strategies in children and adolescents (5 to 19 years) in sub-Saharan Africa.

METHODS

An electronic search was conducted in MEDLINE, EMBASE, Global Health and conference abstract databases. Studies reporting on HTC acceptability, yield and prevalence and published between January 2004 and September 2014 were included. Pooled proportions for these three outcomes were estimated using a random effects model. A quality assessment was conducted on included studies.

RESULTS AND DISCUSSION

A total of 16,380 potential citations were identified, of which 21 studies (23 entries) were included. Most studies were conducted in Kenya (n=5) and Uganda (n=5) and judged to provide moderate (n=15) to low quality (n=7) evidence, with data not disaggregated by age. Seven studies reported on provider-initiated testing and counselling (PITC), with the remainder reporting on family-centred (n=5), home-based (n=5), outreach (n=5) and school-linked HTC among primary schoolchildren (n=1). PITC among inpatients had the highest acceptability (86.3%; 95% confidence interval [CI]: 65.5 to 100%), yield (12.2%; 95% CI: 6.1 to 18.3%) and prevalence (15.4%; 95% CI: 5.0 to 25.7%). Family-centred HTC had lower acceptance compared to home-based HTC (51.7%; 95% CI: 10.4 to 92.9% vs. 84.9%; 95% CI: 74.4 to 95.4%) yet higher prevalence (8.4%; 95% CI: 3.4 to 13.5% vs. 3.0%; 95% CI: 1.0 to 4.9%). School-linked HTC showed poor acceptance and low prevalence.

CONCLUSIONS

While PITC may have high test acceptability priority should be given to evaluating strategies beyond healthcare settings (e.g. home-based HTC among families) to identify individuals earlier in their disease progression. Data on linkage to care and cost-effectiveness of HTC strategies are needed to strengthen policies.

Finding HIV in hard to reach populations: mobile HIV testing and geospatial mapping in Umlazi township, Durban, South Africa

Mobile, community-based HIV testing may help achieve universal HIV testing in South Africa. We compared the yield, geographic distribution, and demographic characteristics of populations tested by mobile- and clinic-based HIV testing programs deployed by iThembalabantu Clinic in Durban, South Africa. From July to November 2011, 4,701 subjects were tested; HIV prevalence was 35 % among IPHC testers and 10 % among mobile testers (p < 0.001). Mobile testers varied in mean age (22-37 years) and % males (26-67 %). HIV prevalence at mobile sites ranged from 0 to 26 %. Testers traveled further than the clinic closest to their home; mobile testers were more likely to test ≥5 km away from home. Mobile HIV testing can improve testing access and identify testing sites with high HIV prevalence. Individuals often access mobile testing sites farther from home than their nearest clinic. Geospatial techniques can help optimize deployment of mobile units to maximize yield in hard-to-reach populations.

Rates of HIV testing and diagnosis in South Africa: successes and challenges

BACKGROUND

UNAIDS aims for 90% of HIV-positive individuals to be diagnosed by 2020, but few attempts have been made in developing countries to estimate the fraction of the HIV-positive population that has been diagnosed.

METHODS

To estimate the rate of HIV diagnosis in South Africa, reported numbers of HIV tests performed in the South African public and private health sectors were aggregated, and estimates of HIV prevalence in individuals tested for HIV were combined. The data were integrated into a mathematical model of the South African HIV epidemic, which was additionally calibrated to estimates of the fraction of the population ever tested for HIV, as reported in three national household surveys.

RESULTS

The fraction of HIV-positive adults who were undiagnosed declined from more than 80% in the early 2000s to 23.7% [95% confidence interval (95% CI) 23.1-24.3] in 2012. The undiagnosed proportion in 2012 was substantially higher in men (31.9%, 95% CI 29.7-34.3) than in women (19.0%, 95% CI 17.9-19.9). Projected probabilities of experiencing disease progression (CD4 cell count <350 cells/μl) without diagnosis are more than 50% for most HIV-positive adults over the age of 40. The fraction of HIV-positive adults who are undiagnosed is projected to decline to 8.9% by 2020 if current targets (10 million tests per annum) are met.

CONCLUSION

South Africa has made significant progress in expanding access to HIV testing, and at current testing rates, the target of 90% of HIV-positive adults diagnosed by 2020 is likely to be reached. However, uptake is relatively low in men and older adults.
