Linkage to care of HIV positive clients in a community based HIV counselling and testing programme: A success story of non-governmental organisations in a South African district

Experiences of nurses in patient adherence to antiretoroviral therapy in Mpumalanga, South Africa

BACKGROUND

 Human immunodeficiency virus (HIV) is a global health pandemic. Mpumalanga is a province with a high burden of HIV or acquired immunodeficiency syndrome (AIDS). Antiretroviral (ARV) therapy should be initiated for all HIV-positive patients. Monitoring of patients' adherence to ARV therapy is important to ensure continued viral suppression.

AIM

 The study aimed to report on the experiences of primary health care (PHC) nurses in monitoring patients' adherence to ARV therapy in PHC facilities in Mpumalanga, South Africa.

SETTING

 Six PHC clinics in a district in Mpumalanga were purposively selected.

METHODS

 Employing a qualitative, exploratory, descriptive research design, 12 PHC nurses were interviewed in 2023. The data were coded, categorised and clustered into themes and categories. Ethical considerations and measures to ensure trustworthiness were adhered to.

RESULTS

 The findings revealed four themes: PHC nurses' experience in monitoring patients' adherence to ARV therapy in PHC facilities, experience of external challenges influencing patient's adherence to ARV therapy, experiences in internal challenges that influence patients' ARV therapy adherence, and the consequences of non-monitoring and poor adherence.

CONCLUSION

 Non-adhering patients were seen to be the greatest challenge. More awareness regarding the central chronic medicine dispensing and distribution (CCMDD) programme and the development of guidelines on the support of PHC nurses and patients are recommended.Contribution: The findings of the study may guide recommendations to assist PHC nurses, PHC management and policy makers at large to address challenges in the monitoring and adherence of patients on ARV therapy.

Absolute CD4 count and percentage values among Libyan patients with HIV by single-platform flow cytometry

BACKGROUND

Single-platform flow cytometry technology together with CD45-gating is becoming the method of choice for absolute CD4 T cell enumeration. Immunological assessment of HIV patients by monitoring CD4 can provide valuable information on antiviral treatment response and disease progression.

METHODS

A total of 97 HIV-positive individuals were recruited from 2 hospitals in Tripoli, Libya, and 14 healthy blood donors. The HIV-infected individuals were classified by CD4+ count into HIV-positive (>200 cells/µL) or AIDS (≤200 cells/µL) groups. CD4+ and CD8+ cell counts were determined and compared among the groups and with similar published data.

RESULTS

The mean ± SD CD4+ cell counts were 1106 ± 442.8 cells/µL in healthy individuals, 460 ± 219.7 cells/µL in the HIV-positive group, and 78 ± 64.3 cells/µL in the AIDS group. The mean ± SD CD4+/CD8+ ratio was 1.6 ± 0.58, 0.4 ± 0.22, and 0.1 ± 0.1, respectively. CD4+ counts in Libyan healthy adults might be higher than those reported in several studies in other regions, whereas CD4+ counts in Libyan AIDS patients seem lower.

CONCLUSION

Reference values for T lymphocyte counts in Libyan healthy individuals should be investigated more extensively, and the reasons why Libyan AIDS patients seem to have such lower CD4+ counts should be examined.

Very high HIV prevalence and incidence among men who have sex with men and transgender women in Indonesia: a retrospective observational cohort study in Bali and Jakarta, 2017-2020

INTRODUCTION

There are no longitudinal HIV incidence data among men who have sex with men (MSM) and transgender women (TGW) in Indonesia. We aimed to estimate HIV prevalence and incidence and identify associated factors among clinic attendees in Jakarta and Bali.

METHODS

We conducted a retrospective cohort study using medical records from five clinics. We reviewed HIV tests among MSM/TGW aged ≥18 years who attended the clinics between 1 January 2018 to 31 December 2020 in Jakarta and 1 January 2017 to 31 December 2019 in Bali. HIV prevalence was measured at the first test. Those with an HIV-negative test and ≥1 follow-up test/s were included in the person-years (PY) at risk to determine HIV incidence. The PY at risk calculation started at the first negative test until the last recorded negative test or seroconversion. Multivariate Poisson regression was used to determine factors associated with HIV acquisition.

RESULTS

Among 5203 and 2815 individuals with an HIV test result in Jakarta and Bali, respectively, at the first HIV test, 1205 and 616 were HIV positive (HIV prevalence 23.2% and 21.9%). The longitudinal sample included 1418 and 873 individuals, respectively. The median number of tests among repeat testers was 3 in Jakarta (interquartile range [IQR] = 2-4) and 3 in Bali (IQR = 2-5). At baseline, about one-quarter were aged <25 years, >90% were MSM and >35% had been tested for HIV previously. In Jakarta, there were 127 HIV seroconversions in 1353 PY (incidence 9.39/100 PY, 95% CI = 7.89-11.17), and in Bali, 71 seroconversions in 982 PY (incidence 7.24/100 PY, 95% CI = 5.73-9.13). Compared to those aged 18-24 years, the incidence rate was lower in older patients (Jakarta-30-39 years: aRR = 0.56, 95% CI = 0.34-0.92; 40+ years: aRR = 0.34, 95% CI = 0.14-0.81; Bali-25-29 years: aRR = 0.44, 95% CI = 0.25-0.79; 30-39 years: aRR = 0.33, 95% CI = 0.18-0.61; 40+ years: aRR = 0.06, 95% CI = 0.01-0.48). In Jakarta, incidence was lower in those with university education than in those without (aRR = 0.66, 95% CI = 0.45-0.96). In Bali, those who had been referred by outreach workers had a higher incidence than those who self-presented for testing (aRR = 1.85, 95% CI = 1.12-3.07).

CONCLUSIONS

We observed very high HIV prevalence and incidence rate estimates. Measures to encourage regular testing and effective use of HIV prevention, including pre-exposure prophylaxis scale-up and demand creation, are needed.

Exploring the role of community health organizations in promoting public health during a health crisis: a qualitative study of COVID-19 responses in South Africa and Zambia

While the COVID-19 pandemic amplified the need for accurate and actionable health information, uncertainty and the proliferation of misinformation have contributed to significant mistrust in public health messages, especially among marginalized communities. Community health organizations can play an important role in creating trust and providing targeted health information to vulnerable groups. This qualitative study, which is focused on community health organizations supporting vulnerable populations in South Africa and Zambia, finds that during the pandemic, community health organizations expanded their roles and leveraged their established access and trust to support the communities they serve with health education and services. However, the reliance on external support limits the organizations' ability to respond in an effective and efficient manner during health crises.

Understanding HIV service preferences of South African women 30-49 years old missing from or linked to care: An exploratory study of Gauteng and Limpopo provinces

BACKGROUND

The HIV epidemic in sub-Saharan Africa has a disproportionate gender impact, with women bearing the brunt of the epidemic. South Africa carries the largest share of the global HIV burden, with similar trends seen for women due to unequal socio-cultural and economic status.

OBJECTIVES

This study aims to understand 30-49 year-old women's barriers and facilitators to accessing HIV services in order to maximize health in resource limited settings and reach women missing from HIV care.

DESIGN

Employing a convenience sampling strategy, we recruited, informed, and consented participants at clinics and public areas. Interviews were conducted in respondent's preferred languages, transcribed verbatim, translated into English if needed, and thematically analyzed using grounded theory.

METHODS

We conducted 81 interviews with women aged 30-49 either missing from care (n = 21), having unknown HIV status (n = 30) or linked to care (n = 30) within two sites: City of Johannesburg district, Gauteng Province and Mopani district, Limpopo Province.

RESULTS

Participants missing from care reported negative staff attitudes, queues, family rejection, medication side effects, and painful blood tests as key deterrents. Participants with an unknown status were deterred by fear of being diagnosed as HIV positive and family rejection, which was similar to women missing from care who often dropped out from care due to actual family rejection. Participants linked to care reported that long queues and staff shortages were challenges but stayed in care due to a will to live for themselves and their children, in addition to counselling and feeling emotionally supported. Interestingly, participants missing from care often accessed medication from friends but, similarly to those with unknown status, noted that they would access care if attended to by supportive nurses and by having non-clinical HIV services.

CONCLUSIONS

The accounts of women in this research highlight significant improvements needed to address inequities in the fight against HIV in South Africa. Additionally, the healthcare service access preferences of women aged 30-49 need to be further explored quantitatively in order to design policy relevant interventions.

Treatment Outcomes After Offering Same-Day Initiation of Human Immunodeficiency Virus Treatment-How to Interpret Discrepancies Between Different Studies

The World Health Organization recommends same-day initiation of antiretroviral therapy (ART) for all persons diagnosed with HIV and ready to start treatment. Evidence, mainly from randomized trials, indicates offering same-day ART increases engagement in care and viral suppression during the first year. In contrast, most observational studies using routine data find same-day ART to be associated with lower engagement in care. We argue that this discrepancy is mainly driven by different time points of enrollment, leading to different denominators. While randomized trials enroll individuals when tested positive, most observational studies start at the time point when ART is initiated. Thus, most observational studies omit those who are lost between diagnosis and treatment, thereby introducing a selection bias in the group with delayed ART. This viewpoint article summarizes the available evidence and argues that the benefits of same-day ART outweigh a potential higher risk of attrition from care after ART initiation.

Contribution of community-based organizations in the improvement of Joint United Nations Program on HIV and AIDS 90-90-90: case of the Yaoundé Central Hospital

Community-based organizations (CBOs) are one of the initiatives implemented in Cameroon to improve access to antiretroviral treatment and influence retention in treatment centers. Despite its importance in the decongestion of patients in health facilities, we do not have data to evaluate the overall impact of these organizations. We conducted a two-part observational study. The first part was a descriptive cross-sectional study, where we included patients screened and initiated on anti-retroviral treatment (ART) either by the approved Treatment center (ATC) of Yaoundé Central Hospital (YCH) or by any of our CBOs in 2020. Then, the second part was a retrospective cohort-type study including patients from the 2015 cohort followed up from 2018 to 2020 in order to assess viral load suppression. As regards the first "90", 7,234 screening tests were performed by CBOs in 2020 out of the 28,302 screening tests registered at the YCH, giving a contribution of 25.6%. From the 7,234 screening tests performed by CBOs, 314 people had an HIV-positive result and 230 (73.34%) were linked to ART through CBOs. From the 28,302 screening tests performed at YCH, 1,089 people had an HIV-positive test, and only 354 (32.50%) were linked to ART, giving a significant difference in the link to ART (P-value < 0.00). Concerning the 3rd ''90'', the viral load suppression rates were respectively in CBOs and at YCH of (95.12% vs 90.54%, RR= 0.51; P-value= 0.27 at 12 months); (95.96% vs 95.34%, relative risk (RR)= 0.85; P-value= 0.81 at 24 months); and (96.91% vs 94.15%, RR= 0.52; P-value = 0.24 at 36 months). In conclusion, we say that the follow-up of patients living with HIV in the community does not negatively affect the evolution of the disease as one might think.

Linkage to HIV Care and Early Retention in Care Rates in the Universal Test-and-Treat Era: A Population-based Prospective Study in KwaZulu-Natal, South Africa

HIV linkage, and retention are key weaknesses in South Africa's national antiretroviral therapy (ART) program, with the greatest loss of patients in the HIV treatment pathway occurring before ART initiation. This study investigated linkage-to and early-retention-in-care (LTRIC) rates among adults newly diagnosed with HIV in a high-HIV prevalent rural district. We conducted an observational prospective cohort study to investigate LTRIC rates for adults with a new HIV diagnosis in South Africa. Patient-level survey and clinical data were collected using a one-stage-cluster design from 18 healthcare facilities and triangulated between HIV and laboratory databases and registered deaths from Department of Home Affairs. We used Chi-square tests to assess associations between categorical variables, and results were stratified by HIV status, sex, and age. Of the 5,637 participants recruited, 21.2% had confirmed HIV, of which 70.9% were women, and 46.5% were aged 25-34 years. Although 82.7% of participants were linked-to-care within 3 months, only 46.1% remained-in-care 12 months after initiating ART and 5.2% were deceased. While a significantly higher proportion of men were linked-to-care at 3 months compared to women, a significant proportion of women (49.5%) remained-in-care at 12 months than men (38.0%). Post-secondary education and child support grants were significantly associated with retention. We found high linkage-to-care rates, but less than 50% of participants remained-in-care at 12 months. Significant effort is required to retain people living with HIV in care, especially during the first year after ART initiation. Our findings suggest that interventions could target men to encourage HIV testing.

Shifting the power: scale-up of access to point-of-care and self-testing for sexually transmitted infections in low-income and middle-income settings

PURPOSE OF REVIEW

Point-of-care (POC) testing for sexually transmitted infections (STIs) can provide complementary coverage to existing HIV testing services in LMICs. This review summarizes current and emerging technologies for detecting STIs in LMICs, with an emphasis on women, discharge-causing infections (chlamydia, gonorrhoea, trichomoniasis, and syphilis), true POC, self-testing, ethics, and economic considerations related to equitable access.

RECENT FINDINGS

The WHO have recently adapted guidelines for treatment of STIs in women that advise the use of true-POC or near-POC tests to improve case finding. The number of rapid, sensitive, and specific POC diagnostics for STIs has increased significantly over the past 10 years, although adoption of these in low-income and middle-income countries (LMICs) remains limited. Barriers to POC adoption by patients include the cost of tests, the inconvenience of lengthy clinic visits, low perceived risk, stigma, lack of partner notification, and lack of trust in healthcare providers. Lowering the cost of true POC lateral flow devices, interfacing these with digital or eHealth technologies, and enabling self-testing/self-sampling will overcome some of these barriers in LMICs. Ensuring linkage of diagnostic tests to subsequent care remains one of the major concerns about self-testing, irrespective of geography, although available evidence from HIV self-testing suggests that linkage to care is similar to that for facility-based testing.

SUMMARY

Increasing access to sensitive STI true POC tests will strengthen reproductive healthcare in LMICs. Although HIV self-testing is demonstrably useful in LMICs, there is an urgent need for randomized trials evaluating the utility and cost-effectiveness of similar tests for other sexually transmitted infections.

Progress towards unique patient identification and case-based surveillance within the Southern African development community

Population mobility makes patient-tracking and care linkage in the South African Development Community (SADC) challenging. Case-based surveillance (CBS) through individual-level clinical data linked with a unique patient-identifier (UPI) is recommended. We conducted a mixed-methods landscape analysis of UPI and CBS implementation within selected SADC countries, this included: (1) SADC UPI implementation literature review; (2) assessment of UPI and CBS implementation for high HIV-prevalence SADC countries; (3) UPI implementation case-study in selected South African primary healthcare (PHC) facilities. Research into CBS and UPI implementation for the SADC region is lacking. Existing patient-identification methods often fail and limit patient-tracking. Paper-based records and poor integration between health-information systems further restrict patient-tracking. Most countries were in the early-middle stages of CBS and faced UPI challenges. Our South African case-study found that the UPI often goes uncaptured. Difficulties tracking patients across prevention and care cascades will continue until a functional and reliable UPI is available.

Evaluation of Community-Based, Mobile HIV-Care, Peer-Delivered Linkage Case Management in Manzini Region, Eswatini

The success of antiretroviral therapy (ART) requires continuous engagement in care and optimal levels of adherence to achieve sustained HIV viral suppression. We evaluated HIV-care cascade costs and outcomes of a community-based, mobile HIV-care, peer-delivered linkage case-management program (CommLink) implemented in Manzini region, Eswatini. Abstraction teams visited referral facilities during July 2019-April 2020 to locate, match, and abstract the clinical data of CommLink clients diagnosed between March 2016 and March 2018. An ingredients-based costing approach was used to assess economic costs associated with CommLink. The estimated total CommLink costs were $2 million. Personnel costs were the dominant component, followed by travel, commodities and supplies, and training. Costs per client tested positive were $499. Costs per client initiated on ART within 7, 30, and 90 days of diagnosis were $2114, $1634, and $1480, respectively. Costs per client initiated and retained on ART 6, 12, and 18 months after diagnosis were $2343, $2378, and $2462, respectively. CommLink outcomes and costs can help inform community-based HIV testing, linkage, and retention programs in other settings to strengthen effectiveness and improve efficiency.

A qualitative inquiry into the patient-related barriers to linkage and retention in HIV care within the community setting

Background

People with the Human Immunodeficiency Virus (PWH) experience barriers to care within the community that impedes their progress from when they discover that they are HIV positive to becoming virally suppressed. For individuals with HIV to achieve sustained viral suppression, they must be linked to care to start receiving anti-retroviral therapy and remain retained in care for continuous treatment. However, HIV surveillance data shows that many PWH are not linked to care and become lost to continuous follow-up care. Although pharmacists, PWH, and social workers interact with one another and are aware of their roles in HIV care, their perspectives on barriers to linkage and retention in care have not been investigated collectively.

Objectives

Explore the perspectives of PWH, pharmacists, and social workers on barriers to linkage and retention of HIV care within the community setting.

Methods

Convenience sampling was used to recruit 15 stakeholders (five PWH, five community pharmacists, and five social workers) who participated in 1-h, semi-structured interviews based on three domains of the Patient-centered Medical Home Model including (1) experiences (individual and system-level barriers to care experienced by PWH), (2) activities (social workers and pharmacists initiatives that impact adherence to care)and (3) interventions (critical issues pharmacists can address in the community to engage PWH in their HIV care). We conducted a directed content analysis based on deductive coding. To establish rigor, we focused on Lincoln and Guba's criteria of rigorous qualitative methodology: credibility, dependability, confirmability, and transferability. Similarities and divergences of themes were discussed during data analysis and agreement was reached before interpretation.

Results

Emergent themes uncovered barriers to linkage and retention in HIV care as HIV-related stigma, having mental health illnesses including a history of substance abuse and social determinants of health such as homelessness, food insecurity, and insurance issues.

Conclusion

The perspectives of pharmacists, social workers, and PWH can provide insight into barriers that should be identified and addressed in people living with HIV to enhance their linkage and retention in care.

Five-Year Mortality for Adults Entering Human Immunodeficiency Virus Care Under Universal Early Treatment Compared With the General US Population

BACKGROUND

Mortality among adults with human immunodeficiency virus (HIV) remains elevated over those in the US general population, even in the years after entry into HIV care. We explore whether the elevation in 5-year mortality would have persisted if all adults with HIV had initiated antiretroviral therapy within 3 months of entering care.

METHODS

Among 82 766 adults entering HIV care at North American AIDS Cohort Collaboration clinical sites in the United States, we computed mortality over 5 years since entry into HIV care under observed treatment patterns. We then used inverse probability weights to estimate mortality under universal early treatment. To compare mortality with those for similar individuals in the general population, we used National Center for Health Statistics data to construct a cohort representing the subset of the US population matched to study participants on key characteristics.

RESULTS

For the entire study period (1999-2017), the 5-year mortality among adults with HIV was 7.9% (95% confidence interval [CI]: 7.6%-8.2%) higher than expected based on the US general population. Under universal early treatment, the elevation in mortality for people with HIV would have been 7.2% (95% CI: 5.8%-8.6%). In the most recent calendar period examined (2011-2017), the elevation in mortality for people with HIV was 2.6% (95% CI: 2.0%-3.3%) under observed treatment patterns and 2.1% (.0%-4.2%) under universal early treatment.

CONCLUSIONS

Expanding early treatment may modestly reduce, but not eliminate, the elevation in mortality for people with HIV.

Acceptability and feasibility of leveraging community-based HIV counselling and testing platforms for same-day oral PrEP initiation among adolescent girls and young women in Eastern Cape, South Africa

INTRODUCTION

Community-based delivery of HIV pre-exposure prophylaxis (PrEP) to South African adolescent girls and young women's (AGYW) could increase access but needs evaluation. We integrated PrEP services via home-based services and pop-up tents into existing community-based HIV testing services (CB-HTS) in Eastern Cape Province, South Africa.

METHODS

After accessing CB-HTS via a "pop-up" tent or home-based services, HIV-negative AGYW aged 16-25 years were invited to complete a baseline questionnaire and referred for PrEP services at a community-based PrEP site co-located with pop-up HTS tents. A 30-day supply of PrEP was dispensed. PrEP uptake, time-to-initiation, cohort characteristics and first medication refill within 90 days were measured using descriptive statistics.

RESULTS

Of the 1164 AGYW who tested for HIV, 825 (74.3%) completed a questionnaire and 806 (97.7%) were referred for community-based PrEP. Of those, 624 (77.4%) presented for PrEP (482/483 [99.8%] from pop-up HTS and 142/323 [44.0%] from home-based HTS), of which 603 (96.6%) initiated PrEP. Of those initiating PrEP following home-based HTS, 59.1% initiated within 0-3 days, 25.6% within 4-14 days and 15.3% took ≥15 days to initiate; 100% of AGYW who used pop-up HTS initiated PrEP the same day. Among AGWY initiating PrEP, 37.5% had a detectable sexually transmitted infection (STI). Although AGYW reported a low self-perception of HIV risk, post-hoc application of HIV risk assessment measures to available data classified most study participants as high risk for HIV acquisition. Cumulatively, 329 (54.6%) AGYW presented for a first medication refill within 90 days of accepting their first bottle of PrEP.

CONCLUSIONS

Leveraging CB-HTS platforms to provide same-day PrEP initiation and refill services was acceptable to AGYW. A higher proportion of AGYW initiated PrEP when co-located with CB-HTS sites compared to those referred following home-based HTS, suggesting that proximity of CB-HTS and PrEP services facilitates PrEP uptake among AGYW. The high prevalence of STIs among those initiating PrEP necessitates the integration of STI and HIV prevention programs for AGYW. Eligibility for PrEP initiation should not be required among AHYW in high HIV burden communities. Community-based service delivery will be crucial to maintaining access to PrEP services during the COVID-19 pandemic and future health and humanitarian emergencies.

Management in the care of people with HIV in primary health care in times of the new coronavirus

OBJECTIVE

To understand management practices in the care of people living with the human immunodeficiency virus (HIV) in primary health care in a Brazilian capital, in times of the new coronavirus (covid-19) pandemic.

METHOD

Qualitative research, anchored in the methodological-analytical framework of the grounded theory, constructivist aspect. Data were collected by using intensive online interviews with nurses from health centers and managers of the municipal health department. Data collection and analysis occurred concomitantly in two phases of analysis: initial and focused coding.

RESULTS

They point to the development of best care practices, with emphasis on initiatives for coordination of care, decentralization of clinical management for primary health care services, establishment of protocols and flows, agreement of intersectoral partnerships, use of groups and social networks, use of tools such as teleconsultation and health surveillance spreadsheet and formation of support networks.

CONCLUSION

The Brazilian capital restructured its network of health services with the implementation of clinical and management protocols, seeking to maintain care for people living with HIV. We highlighted the incorporation of non-face-to-face care technologies and the facilitation of routines, as strategies for expanding access.

Perspectives on linkage to care for patients diagnosed with HIV: A qualitative study at a rural health center in South Western Uganda

Linkage to care for newly diagnosed human immunodeficiency virus (HIV) patients is important to ensure that patients have good access to care. However, there is little information about factors influencing linkage to care for HIV patients. We aimed to identify existing measures in place that promote linkage to care and to explore facilitators and barriers to linkage to care for clients diagnosed with HIV/acquired immune deficiency syndrome at a rural health center in Uganda. This descriptive qualitative study enrolled 33 purposively selected participants who included expert clients, linkage facilitators, heads of families with people living with HIV, and health workers. Data were collected using in-depth interviews that were audio-recorded, transcribed, and translated. The data were manually analyzed to generate themes. The following four themes were generated: 1) availability of services that include counseling, testing, treatment, follow-up, referral, outreach activities, and support systems. 2) Barriers to linkage to care were at the individual, health facility, and community levels. Individual-level barriers were socioeconomic status, high transport costs, fear of adverse drug effects, fear of broken relationships, and denial of positive results or treatment, while health facility barriers were reported to be long waiting time, negative staff attitude, and drug stock outs. Community barriers were mostly due to stigma experienced by HIV clients, resulting in discrimination by community members. 3) Facilitators to linkage to care were positive staff attitudes, access to information, fear of death, and support from others. 4) Suggestions for improving service delivery were shortening waiting time, integrating HIV services, increasing staff numbers, and intensifying outreaches. Our findings highlight the importance of stakeholder involvement in linkage to care. Access and linkage to care are positively and negatively influenced at the individual, community, and health facility levels. However, integration of HIV services and intensifying outreaches are key to improving linkage to care.

Factors Associated with Linkage to Care following Community-Level Identification of HIV-Positive Clients in Lira District

Background

Community HIV testing helps to increase access to high-risk groups who are less likely to visit a clinic for a test. A large proportion of people identified with HIV following community-based testing are not easily linked to care compared to facility-based identified cases. There is a paucity of literature on linkage to HIV care and its predictors particularly following community-based testing in a rural setting. We assessed the level of linkage to the care of HIV-positive individuals and associated factors following community-level identification in Lira district.

Method

A cross-sectional survey was conducted in Lira district employing mixed methods among HIV-positive adults identified in the communities. Quantitative data were collected from 329 randomly selected study participants using interviewer-administered questionnaires. Key informant interview guide was used to collect qualitative data. The data were double entered, cleaned, and analyzed using SPSS version 23. Odds ratios and confidence intervals were used to assess the association between predictors of linkage with HIV care. Qualitative data were analyzed using thematic content analysis.

Results

The respondents were aged between 18 and 85 years with a mean age of 42.9 (SD = 11.6). The level of linkage to HIV care following community-level identification of HIV testing in Lira district was 98% (95% CI 96.07-99.33). Clients who self-initiated the HIV testing were more likely to link to HIV care than their counterparts (AOR = 9.03; 95% CI 1.271-64.218, p = 0.028). Key informants identified factors influencing linkage to care as health education, counseling, follow-up, and family support. Fear of stigma, disclosure, denial, and distance to facility were reported as barriers to linkage.

Conclusion/Recommendation

The level of linkage to HIV care following community identification was found to be excellent (98%). Predictors to linkage to care included self-initiated testing, positive perception of distance, and waiting time at health facilities. We recommend health education, counseling, follow-up, and family support as interventions to strengthen successfully linking to care.

Intersecting Stigma and HIV/AIDS Community Participation Among Young Chinese Men Who Have Sex with Men Living with HIV

Community participation is vital for the recovery and empowerment of men who have sex with men (MSM) living with HIV. Intersectionality also provides an important lens that inequalities operate in an intersectional manner and pose compound challenges to the lives of minority individuals. However, the association between intersecting stigma toward HIV-positive MSM and their community participation is underexplored. The study drew on a sample of young Chinese MSM living with HIV from a community-based online survey that recruited respondents using nonprobability purposive sampling (n = 1004). Structural equation modeling was performed to investigate the associations among perceived stigma against sexual minorities and people living with HIV, HIV-related self-stigma, and HIV/AIDS community participation. The indirect effect of self-stigma and the statistical interaction between perceived homosexual stigma and perceived HIV-related stigma were further examined. Results show that total direct effect was significant [B (SE) = 0.859 (0.233); confidence interval (95% CI) = 0.402-1.316]. Perceived HIV-related stigma was positively correlated with HIV/AIDS community participation, while HIV-related self-stigma was negatively correlated. The mediating role of HIV-related self-stigma was significant in both types of perceived stigma [total indirect effect: B (SE) = -0.935 (0.175); 95% CI = -1.277 to -0.593]. The interaction effect was also significant and negative [B (SE) = -0.117 (0.056), p < 0.001], showing that perceived homosexual stigma could offset the effect of perceived HIV-related stigma on HIV-related self-stigma. The findings illustrate how intersecting stigma is involved in HIV-related self-stigma and community participation and highlight the importance of applying an intersectionality perspective to investigate stigma toward MSM living with HIV and their community participation.

The geography of emergency department-based HIV testing in South Africa: Can patients link to care?

BACKGROUND

Emergency Departments (EDs) can serve as clinical sites for identification of new HIV infections and their entry into care. We examined if HIV-positive patients who present to EDs in South Africa are able to successfully link to care.

METHODS

We conducted a one-year longitudinal prospective cohort study in four hospitals across the Eastern Cape, South Africa, with participants followed between July 2016 and July 2018. All adult, non-critical patients presenting to the ED were systematically approached, asked about their HIV status, and, if unknown, offered a point-of-care (POC) HIV test. All HIV-positive patients were further consented to participate in a follow-up study to assess subsequent linkage to care and distance from "home" to ED. Linkage to care was defined as self-reported linkage (telephonic) or evidence of repeated CD4/viral load testing in the National Health Laboratory System (NHLS) at either the 6- or 12-months post index ED visit.

FINDINGS

A total of 983 HIV-positive patients consented to participate in the study. In the 12 months following their ED visit, 34·1% of patients demonstrated linkage to care (335/983), 23·8% did not link to care (234/983), and 42·1% (414/983) were lost to follow-up. Though not statistically significant, a high percentage of young men (27/50, 54%) and those presenting with a trauma-related complaints (100/205, 48.8%) did not link to care. A considerable proportion of patients (105/454, 23·2%,) resided 50 or more kilometers from their index ED sites, though there was not a significant difference in linkage to care rate between those who lived closer or further from the ED.

INTERPRETATION

We have shown that strategies to improve linkage to care from the ED should consider the high rates of poor linkage among young men and those presenting to the ED with trauma. Furthermore, innovative linkage to care solutions will need to account for the unique geographical consideration of this population, given that many ED patients will need to continue care at a site distant from the diagnosis site.

Patterns of engagement in HIV care during pregnancy and breastfeeding: findings from a cohort study in North-Eastern South Africa

BACKGROUND

Eliminating mother-to-child transmission of HIV (MTCT) in sub-Saharan Africa is hindered by limited understanding of HIV-testing and HIV-care engagement among pregnant and breastfeeding women.

METHODS

We investigated HIV-testing and HIV-care engagement during pregnancy and breastfeeding from 2014 to 2018 in the Agincourt Health and Demographic Surveillance System (HDSS). We linked HIV patient clinic records to HDSS pregnancy data. We modelled time to a first recorded HIV-diagnosis following conception, and time to antiretroviral therapy (ART) initiation following diagnosis using Kaplan-Meier methods. We performed sequence and cluster analyses for all pregnancies linked to HIV-related clinic data to categorise MTCT risk period engagement patterns and identified factors associated with different engagement patterns using logistic regression. We determined factors associated with ART resumption for women who were lost to follow-up (LTFU) using Cox regression.

RESULTS

Since 2014, 15% of 10,735 pregnancies were recorded as occurring to previously (51%) or newly (49%) HIV-diagnosed women. New diagnoses increased until 2016 and then declined. We identified four MTCT risk period engagement patterns (i) early ART/stable care (51.9%), (ii) early ART/unstable care (34.1%), (iii) late ART initiators (7.6%), and (iv) postnatal seroconversion/early, stable ART (6.4%). Year of delivery, mother's age, marital status, and baseline CD4 were associated with these patterns. A new pregnancy increased the likelihood of treatment resumption following LTFU.

CONCLUSION

Almost half of all pregnant women did not have optimal ART coverage during the MTCT risk period. Programmes need to focus on improving retention, and leveraging new pregnancies to re-engage HIV-positive women on ART.

Usability and Clinical Performance Characteristics of the Asante HIV1/2 Test by Trained Users in Two African Sites

HIV self-testing (HIVST) devices are acknowledged as having the potential to enable the acceleration of HIV diagnosis and linkage to care. How efficiently professional and trained users engaged with the Asante HIV-1/2 Oral Self-Test (Asante) (Sedia Biosciences, Portland, OR, USA), and the accuracy of the device in comparison to other HIV rapid diagnostic tests (RDT), was assessed to be able to guide the development and adoption of the device in Senegal and South Africa. Using convenience sampling, potential participants were recruited from catchment areas where HIV was prevalent. Trained users performed an HIV test on participants using an Oral HIVST. The professional user’s interpretation of results was then measured against the results of various other RDTs. The South African study had 1652 participants and the Senegalese, 500. Most of the participants in each study were 18–35 years old. Senegal had a higher number of females (346/500, 69.2%) compared to South Africa (699/1662, 42.1%). Asante displayed very high sensitivity and specificity when tested against other devices. In the final enzyme-linked immunosorbent assay (ELISA) comparison, in South Africa, the sensitivity: specificity was 99.1:99.9% and in Senegal, 98.4:100.0%. Senegal further identified 53/63 (84.1%) with HIV-1, 8/63 (12.7) with HIV-2 and 2/63 (3.2%) with HIV-1/2 co-infections. Professional or trained users’ interpretations of Asante results correlated strongly to results when using various RDTs, the ELISA assay and Western blot tests, making it a dependable HIV testing instrument.

Geographical variation in HIV testing in South Africa: Evidence from the 2017 national household HIV survey

Background

Identification of the geographical areas with low uptake of HIV testing could assist in spatial targeting of interventions to improve the uptake of HIV testing.

Objectives

The objective of this research study was to map the uptake of HIV testing at the district level in South Africa.

Method

The secondary analysis used data from the Human Sciences Research Council's 2017 National HIV Prevalence, Incidence, Behaviour and Communication Survey, where data were collected using a multistage stratified random cluster sampling approach. Descriptive spatial methods were used to assess disparities in the proportion of those ever tested for HIV at the district level in South Africa.

Results

The districts with the highest overall coverage of people ever having tested for HIV (> 85%) include West Rand in Gauteng, Lejweleputswa and Thabo Mofutsanyane in Free State, and Ngaka Modiri Molema in North-West. These provinces also had the least variation in HIV testing coverage between their districts. Districts in KwaZulu-Natal had the widest variation in coverage of HIV testing. The districts with the lowest uptake of HIV testing were uMkhanyakude (54.7%) and Ugu (61.4%) in KwaZulu-Natal and Vhembe (61.0%) in Limpopo. Most districts had a higher uptake of HIV testing amongst female than male participants.

Conclusion

The uptake of HIV testing across various districts in South Africa seems to be unequal. Intervention programmes must improve the overall uptake of HIV testing, especially in uMkhanyakude and Ugu in KwaZulu-Natal and Vhembe in Limpopo. Interventions must also focus on enhancing uptake of HIV testing amongst male participants in most districts. Strategies that would improve the uptake of HIV testing include HIV self-testing and community HIV testing, specifically home-based testing.

Predictors of antiretroviral therapy interruptions and factors influencing return to care at the Nkolndongo Health District, Cameroon

BACKGROUND

Antiretroviral therapy is a lifelong commitment that requires consistent intake of tablets to optimize health outcomes, attain and maintain viral suppression.

OBJECTIVE

We aimed to elicit predictors of treatment interruption amongst PLHIV and identify motivating factors influencing return to care.

METHOD

We conducted a cross-sectional study using a mixed-method approach in four hospitals in Yaoundé. Sociodemographic and clinical data were collected from ART registers. Using purposeful sampling, thirteen participants were enrolled for interviews. Quantitative data were analyzed using Epi-Info and Atlas-TI for qualitative analysis. Ethical clearance approved by CBCHS-IRB.

RESULTS

A total of 271 participants records were assessed. The mean age was 33 years (SD±11years). Private facilities CASS and CMNB registered respectively 53 (19.6%) and 14 (5.2%) participants while CMA Nkomo and IPC had 114 (42.1%) and 90 (33.2%) participants. Most participants (75.3%) were females [OR 1.14; CI 0.78-1.66] compare with males. 78% had no viral load test results. Transport cost and stigmatization constituted the most prominent predictors of treatment interruption (47.5%) and (10.5%) respectively. Belief in the discovery of an eminent HIV cure and the desire to raise offspring motivated 30% and 61%, respectively to resume treatment.

CONCLUSION

Structural barriers like exposed health facility, and dispensing ARVs in open spaces stigmatizes clients and increases odds of attrition. Attrition of patients on ART will be minimized through implementation of client centered approaches like multiplying proxy ART pick points, devolving stable clients to community ARV model.

Test and Prevent: Evaluation of a Pilot Program Linking Clients With Negative HIV Test Results to Pre-exposure Prophylaxis in Zimbabwe

BACKGROUND

As HIV testing increases worldwide, programs are reaching individuals without HIV infection who are at risk of exposure and may be candidates for oral pre-exposure prophylaxis (PrEP). Although linkage of individuals with HIV infection to treatment is a global priority (referred to as "test and treat"), less attention is given to individuals with negative HIV test results. We developed the "Test and Prevent" pilot program to intentionally link at-risk clients with negative HIV test results to PrEP services. The intervention included risk assessment of all clients with a negative result from HIV testing (with national risk assessment tool), accompanied referral, fast-tracking, and targeting follow-up.

METHODS

The intervention was conducted in Bulawayo, Zimbabwe, at 6 public sector sites from October 2019 to February 2020. We collected routine monitoring data from all study sites and tracked referral completion and PrEP initiation among clients who enrolled. We conducted in-depth interviews with providers (n=12), facility managers (n=5), and female clients (n=17) to explore acceptability.

RESULTS

Among clients referred for PrEP (n=206), 98% completed their referrals and started PrEP. However, only 3% of clients who received a negative test result during the study period were referred. Low referrals stemmed from lack of screening (39% of clients with negative HIV test results were not screened) and lack of eligibility among clients who were screened (only 6% of those screened qualified as candidates for PrEP per the national screening tool). Qualitative results indicate that some providers purposefully did not complete screening with clients they felt were not at risk and that workload could have contributed to low screening uptake.Qualitative interviews showed that Test and Prevent was acceptable among both providers and clients. Clients were happy to learn about PrEP following HIV testing, and the additional support of accompanied referrals and fast-tracking encouraged them to access PrEP and made them feel valued. Providers were burdened by workload constraints but felt that Test and Prevent was important and should be scaled to other sites.

CONCLUSION

Intentionally linking clients with negative results to PrEP immediately following HIV testing was found to be acceptable from both provider and client perspectives, yet screening procedures need closer examination and reinforcement for the program to realize a larger impact.

Ethical Implications of eHealth Tools for Delivering STI/HIV Laboratory Results and Partner Notifications

Purpose of Review

eHealth tools are increasingly utilized for communication with patients. Although efficacious and cost-effective, these tools face several barriers that challenge their ethical use in sexual health. We reviewed literature from the past decade to pick illustrative studies of eHealth tools that deliver results of laboratory tests for sexually transmitted infections, including the human immunodeficiency virus, as well as partner notifications. We describe ethical implications for such technologies.

Recent Findings

Our review found that despite widespread research on the use of eHealth tools in delivering laboratory results and partner notifications, these studies rarely measured or reported on the ethical implications. Such implications can be organized according to the four major principles in bioethics: beneficence, patient autonomy, non-maleficence, and justice. The beneficence of eHealth typically measures efficacy in comparison to existing standards of care. Patient autonomy includes the ability to opt in or out of eHealth tools, right-based principles of consent, and sovereignty over healthcare data. To adhere to the principle of non-maleficence, relevant harms must be identified and measured—such as unintentional disclosure of illness, sexual orientation, or sexual activity. Justice must also be considered to accommodate all users equally, irrespective of their literacy level, with easy-to-use platforms that provide clear messages.

Summary

Based on case studies from this review, we developed a list of recommendations for the ethical development and evaluation of eHealth platforms to deliver STI/HIV results to patients and notifications to partners.

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.

A Cascade of Interventions to Promote Adherence to Antiretroviral Therapy in African Countries

Purpose of Review

We reviewed interventions to improve uptake and adherence to antiretroviral therapy (ART) in African countries in the Treat All era.

Recent Findings

ART initiation can be improved by facilitated rapid receipt of first prescription, including community-based linkage and point-of-care strategies, integration of HIV care into antenatal care and peer support for adolescents. For people living with HIV (PLHIV) on ART, scheduled SMS reminders, ongoing intensive counselling for those with viral non-suppression and economic incentives for the most deprived show promise. Adherence clubs should be promoted, being no less effective than facility-based care for stable patients. Tracing those lost to follow-up should be targeted to those who can be seen face-to-face by a peer worker.

Summary

Investment is needed to promote linkage to initiating ART and for differentiated approaches to counselling for youth and for those with identified suboptimal adherence. More evidence from within Africa is needed on cost-effective strategies to identify and support PLHIV at an increased risk of non-adherence across the treatment cascade.

Exploring HIV-Related Stigma and Discrimination at the Workplace in Southwestern Uganda: Challenges and Solutions

Globally, the HIV/AIDS pandemic continues to have an enormous impact on affected societies. Despite several health promotion interventions being carried out, HIV/AIDS remains a major cause of deaths in low and middle income countries. At the workplace, the pandemic has brought about reduction in productivity, increased staff turnover, increased production costs, high levels of stigma, etc. HIV stigma is one of the main reasons why the pandemic has continued to devastate a number of societies around the world. HIV stigma presents barriers to HIV prevention in different settings including the workplace. Unlike large enterprises, small-scale enterprises have received less attention in the fight against HIV/AIDS. This study’s purpose was to explore how employers and employees can overcome challenges of HIV-related stigma at the workplace. This study employed a qualitative case study design. Data were collected from eighteen participants in three small-scale enterprises in Kabale. Findings indicate that small-scale enterprises are faced with the fear of HIV testing, status disclosure, staff turnover, suicidal thoughts, gossip, etc. Implementing operative national HIV workplace policies may enable small-scale enterprises to overcome challenges of HIV-related stigma at the workplace.

"Vital": HIV counselling and testing staff's views of addressing mental health with HIV in Uganda

BACKGROUND

Mental health is linked to HIV outcomes, including linkage into care and adherence to medication. Integrated care for mental and physical health is recommended. HIV testing and counselling sessions represent an opportunity to implement interventions to address mental health, however it is first necessary to understand the roles, current practice, knowledge and attitudes of the testing and counselling staff.

METHODS

This qualitative study used semi-structured interviews with HIV testing and counselling staff at four centres of a HIV healthcare provider charity in Uganda. Interviews focused on their current practice, perceptions of mental health and their role in supporting this, challenges of this work, training and support needs, and views of potential greater emphasis on mental health work in their role. Data were audio-recorded, transcribed verbatim, and analysed thematically.

RESULTS

Data from twenty-one testing and counselling staff revealed five themes. Clients presented to counselling staff with needs spanning bio-psycho-social domains, where psychological health was intertwined with HIV management, medication adherence, and seen as "inseparable" from HIV itself. Mental health was largely thought about as "madness", identifiable from extreme behaviour. As such, common mental health problems of anxiety and depression were not often seen as part of mental health. Approaches to intervening with mental health were seen as behavioural, with some ideas about changing thinking styles. Participants demonstrated significant practice of common techniques to address mental health. Needs were identified for further training in suicide risk assessment and identification of depression, together with greater clinical supervision. Participants described significant conflict within their roles, particularly balancing time demands and need to achieve testing targets against the need to offer adequate mental health support to clients in need.

CONCLUSIONS

HIV testing and counselling staff described a diverse role that already includes addressing mental health. Mental health is "vital" to their work, however the time needed to address it is at odds with current testing targets. They require more training and resources to effectively address mental health, which is vital to optimising HIV outcomes. Interventions to integrate mental health support into HIV testing and counselling sessions need to be further researched and optimised.

Diagnostic Infectious Diseases Testing Outside Clinics: A Global Systematic Review and Meta-analysis

BACKGROUND

Most people around the world do not have access to facility-based diagnostic testing, and the gap in availability of diagnostic tests is a major public health challenge. Self-testing, self-sampling, and institutional testing outside conventional clinical settings are transforming infectious disease diagnostic testing in a wide range of low- and middle-income countries (LMICs). We examined the delivery models of infectious disease diagnostic testing outside clinics to assess the impact on test uptake and linkage to care.

METHODS

We conducted a systematic review and meta-analysis, searching 6 databases and including original research manuscripts comparing testing outside clinics with conventional testing. The main outcomes were test uptake and linkage to care, delivery models, and adverse outcomes. Data from studies with similar interventions and outcomes within thematic areas of interest were pooled, and the quality of evidence was assessed using GRADE. This study was registered in PROSPERO (CRD42019140828).We identified 10 386 de-duplicated citations, and 76 studies were included. Data from 18 studies were pooled in meta-analyses. Studies focused on HIV (48 studies), chlamydia (8 studies), and multiple diseases (20 studies). HIV self-testing increased test uptake compared with facility-based testing (9 studies: pooled odds ratio [OR], 2.59; 95% CI, 1.06-6.29; moderate quality). Self-sampling for sexually transmitted infections increased test uptake compared with facility-based testing (7 studies: pooled OR, 1.74; 95% CI, 0.97-3.12; moderate quality). Conclusions.  Testing outside of clinics increased test uptake without significant adverse outcomes. These testing approaches provide an opportunity to expand access and empower patients. Further implementation research, scale-up of effective service delivery models, and policies in LMIC settings are needed.

Increasing pediatric HIV testing positivity rates through focused testing in high-yield points of service in health facilities-Nigeria, 2016-2017

Background

In 2017, UNAIDS estimated that 140,000 children aged 0–14 years are living with HIV in Nigeria, but only 35% have been diagnosed and are receiving antiretroviral therapy. Children are tested primarily in outpatient clinics, which show low HIV-positive rates. To demonstrate efficient facility-based HIV testing among children aged 0–14 years, we evaluated pediatric HIV-positivity rates in points of service in select health facilities in Nigeria.

Methods

We conducted a retrospective analysis of HIV testing and case identification among children aged 0–14 years at all points of service at nine purposively sampled hospitals (November 2016–March 2017). Points of service included family index testing, pediatric outpatient department (POPD), tuberculosis (TB) clinics, immunization clinics, and pediatric inpatient ward. Eligibility for testing at POPD was done using a screening tool while all children with unknown status were eligible for HIV test at other points of service. The main outcome was HIV positivity rates stratified by the testing point of service and by age group. Predictors of an HIV-positive result were assessed using logistic regression. All analyses were done using Stata 15 statistical software.

Results

Of 2,180 children seen at all facility points of service with unknown HIV status, 1,822 (83.6%) were tested for HIV, of whom 43 (2.4%) tested HIV positive. The numbers of children tested by age group were <1 years = 230 (12.6%); 1–4 years = 752 (41.3%); 5–9 years = 520 (28.5%); and 10–14 years = 320 (17.6%). The number of children tested by point of service were POPD = 906 (49.7%); family index testing = 693 (38.0%); pediatric inpatient ward = 192 (10.5%); immunization clinic = 16 (0.9%); and TB clinic = 15 (0.8%). HIV positivity rates by point of service were TB clinic = 6.7% (95% Confidence Interval (CI): 0.9–35.2%); pediatric inpatient ward = 4.7% (95%CI: 2.5–8.8%); family index testing = 3.5% (95%CI: 2.3–5.1%); POPD = 1.0% (95%CI: 0.5–1.9%); and immunization clinic = 0%. The percentage contribution to total HIV positive children found by point of services was: family index testing = 55.8% (95%CI: 40.9–69.8%); POPD = 20.9% (95%CI: 11.3–35.6%); inpatient ward = 20.9 (95%CI: 11.3–35.6%) and TB Clinic = 2.3% (95%CI: 0.3–14.8%). Compared with the POPD, the adjusted odds ratio (95% CI) for finding an HIV positive child by point of service were TB clinic = 7.2 (95% CI: 0.9–60.9); pediatric inpatient ward = 4.9 (95% CI: 1.9–12.8); and family index testing = 3.7 (95% CI: 1.5–8.8). HIV-positivity rates did not significantly differ by age group.

Conclusion

In Nigeria, to improve facility-based HIV positivity rates among children aged 0–14 years, an increased focus on HIV testing among children seeking care in pediatric inpatient wards, through family index testing, and perhaps TB clinics is appropriate.

Comparison of community-based HIV counselling and testing (CBCT) through index client tracing and other modalities: Outcomes in 13 South African high HIV prevalence districts by gender and age

BACKGROUND

To increase HIV case finding in a Community-based HIV counselling and testing (CBCT) programme, an index client tracing modality was implemented to target index clients' sexual network and household members.

OBJECTIVE

To compare index client tracing modality's outcomes with other CBCT recruitment modalities (mobile, workplace, homebased), 2015-2017.

METHODS

Trained HIV counsellors identified HIV positive clients either through offering HIV tests to children and sexual partners of an HIV index client, or randomly offering HIV tests to anyone available in the community (mobile, home-based or workplace). Socio-demographic information and test results were recorded. Descriptive comparisons of client HIV test uptake and positivity were conducted by method of recruitment-index client tracing vs non-targeted community outreach.

RESULTS

Of the 1 282 369 people who tested for HIV overall, the index modality tested 3.9% of them, 1.9% in year 1 and 6.0% in year 2. The index modality tested more females than males (55.8% vs 44.2%) overall and in each year; tested higher proportions of children than other modalities: 10.1% vs 2.6% among 1-4 years, 12.2% vs 2.6% among the 5-9 years and 9.6% vs 3.4% among the 10-15 years. The index modality identified higher HIV positivity proportions than other modalities overall (10.3% 95%CI 10.0-10.6 vs. 7.3% 95%CI 7.25-7.36), in year 1 (9.4%; 8.9-9.9 vs 6.5%; 6.45-6.57) and year 2 (10.6%; 10.3-10.9 vs 8.2%; 8.09-8.23). Higher proportions of females (7.5%;7.4-7.5) than males (5.5%;5.4-5.5) tested positive overall. Positivity increased by age up to 49y with year 2's increased targeting of sexual partners. Overall linkage to care rose from 33.3% in year 1 to 78.9% in year 2.

CONCLUSIONS

Index testing was less effective in reaching large numbers of clients, but more effective in reaching children and identifying HIV positive people than other modalities. Targeting HIV positive people's partners and children increases HIV case finding.
