Implementing universal HIV treatment in a high HIV prevalence and rural South African setting - Field experiences and recommendations of health care providers

Strategies to improve antiretroviral therapy (ART) initiation and early engagement among men in sub-Saharan Africa: A scoping review of interventions in the era of universal treatment

OBJECTIVES

Men in sub-Saharan Africa (SSA) have lower rates of antiretroviral therapy (ART) initiation and higher rates of early default than women. Little is known about effective interventions to improve men's outcomes. We conducted a scoping review of interventions aimed to increase ART initiation and/or early retention among men in SSA since universal treatment policies were implemented.

METHODS

Three databases, HIV conference databases and grey literature were searched for studies published between January 2016 to May 2021 that reported on initiation and/or early retention among men. Eligibility criteria included: participants in SSA, data collected after universal treatment policies were implemented (2016-2021), quantitative data on ART initiation and/or early retention for males, general male population (not exclusively focused on key populations), intervention study (report outcomes for at least one non-standard service delivery strategy), and written in English.

RESULTS

Of the 4351 sources retrieved, 15 (reporting on 16 interventions) met inclusion criteria. Of the 16 interventions, only two (2/16, 13%) exclusively focused on men. Five (5/16, 31%) were randomised control trials (RCT), one (1/16, 6%) was a retrospective cohort study, and 10 (10/16, 63%) did not have comparison groups. Thirteen (13/16, 81%) interventions measured ART initiation and six (6/16, 37%) measured early retention. Outcome definitions and time frames varied greatly, with seven (7/16, 44%) not specifying time frames at all. Five types of interventions were represented: optimising ART services at health facilities, community-based ART services, outreach support (such as reminders and facility escort), counselling and/or peer support, and conditional incentives. Across all intervention types, ART initiation rates ranged from 27% to 97% and early retention from 47% to 95%.

CONCLUSIONS

Despite years of data of men's suboptimal ART outcomes, there is little high-quality evidence on interventions to increase men's ART initiation or early retention in SSA. Additional randomised or quasi-experimental studies are urgently needed.

Healthcare provider perceptions on the implementation of the universal test-and-treat policy in South Africa: a qualitative inquiry

BACKGROUND

South Africa had an estimated 7.5 million people living with HIV (PLHIV), accounting for approximately 20% of the 38.4 million PLHIV globally in 2021. In 2015, the World Health Organization recommended the universal test and treat (UTT) intervention which was implemented in South Africa in September 2016. Evidence shows that UTT implementation faces challenges in terms of human resources capacity or infrastructure. We aim to explore healthcare providers (HCPs)' perspectives on the implementation of the UTT strategy in uThukela District Municipality in KwaZulu-Natal province.

METHODS

A qualitative study was conducted with one hundred and sixty-one (161) healthcare providers (HCPs) within 18 healthcare facilities in three subdistricts, comprising of Managers, Nurses, and Lay workers. HCPs were interviewed using an open ended-survey questions to explore their perceptions providing HIV care under the UTT strategy. All interviews were thematically analysed using both inductive and deductive approaches.

RESULTS

Of the 161 participants (142 female and 19 male), 158 (98%) worked at the facility level, of which 82 (51%) were nurses, and 20 (12.5%) were managers (facility managers and PHC manager/supervisors). Despite a general acceptance of the UTT policy implementation, HCPs expressed challenges such as increased patient defaulter rates, increased work overload, caused by the increased number of service users, and physiological and psychological impacts. The surge in the workload under conditions of inadequate systems' capacity and human resources, gave rise to a greater burden on HCPs in this study. However, increased life expectancy, good quality of life, and immediate treatment initiation were identified as perceived positive outcomes of UTT on service users. Perceived influence of UTT on the health system included, increased number of patients initiated, decreased burden on the system, meeting the 90-90-90 targets, and financial aspects.

CONCLUSION

Health system strengthening such as providing more systems' capacity for expected increase in workload, proper training and retraining of HCPs with new policies in the management of patient readiness for lifelong ART journey, and ensuring availability of medicines, may reduce strain on HCPs, thus improving the delivery of the comprehensive UTT services to PLHIV.

Implementation and effectiveness of a linkage to HIV care intervention in rural South Africa (ANRS 12249 TasP trial)

BACKGROUND

Timely linkage to care and ART initiation is critical to decrease the risks of HIV-related morbidity, mortality and HIV transmission, but is often challenging. We report on the implementation and effectiveness of a linkage-to-care intervention in rural KwaZulu-Natal, South Africa.

METHODS

In the ANRS 12249 TasP trial on Universal Testing and Treatment (UTT) implemented between 2012-2016, resident individuals ≥16 years were offered home-based HIV testing every six months. Those ascertained to be HIV-positive were referred to trial clinics. Starting May 2013, a linkage-to-care intervention was implemented in both trial arms, consisting of tracking through phone calls and/or home visits to "re-refer" people who had not linked to care to trial clinics within three months of the first home-based referral. Fidelity in implementing the planned intervention was described using Kaplan-Meier estimation to compute conditional probabilities of being tracked and of being re-referred by the linkage-to-care team. Effect of the intervention on time to linkage-to-care was analysed using a Cox regression model censored for death, migration, and end of data follow-up.

RESULTS

Among the 2,837 individuals (73.7% female) included in the analysis, 904 (32%) were tracked at least once, and 573 of them (63.4%) were re-referred. Probabilities of being re-referred was 17% within six months of first referral and 31% within twelve months. Compared to individuals not re-referred by the intervention, linkage-to-care was significantly higher among those with at least one re-referral through phone call (adjusted hazard ratio [aHR] = 1.82; 95% confidence interval [95% CI] = 1.47-2.25), and among those with re-referral through both phone call and home visit (aHR = 3.94; 95% CI = 2.07-7.48).

CONCLUSIONS

Phone calls and home visits following HIV testing were challenging to implement, but appeared effective in improving linkage-to-care amongst those receiving the intervention. Such patient-centred strategies should be part of UTT programs to achieve the UNAIDS 95-95-95 targets.

Universal Health Coverage for Antiretroviral Treatment: A Review

Universal health coverage is essential for the progress to end threats of the acquired immunodeficiency syndrome epidemic. The current review assesses the publication rate, strategies and barriers for antiretroviral therapy (ART) coverage, equity, quality of care, and financial protection. We searched Web of Science, PubMed, and Google Scholar. Of the available articles, 43.13% were on ART coverage, 40.28% were on financial protection, 10.43% were on quality of care, and 6.16% were on equity. A lack of ART, fear of unwanted disclosure, lack of transportation, unaffordable health care costs, long waiting time to receive care, and poverty were barriers to ART coverage. Catastrophic health care costs were higher among individuals who were living in rural settings, walked greater distances to reach health care institutions, had a lower socioeconomic status, and were immunocompromised. There were challenges to the provision of quality of care, including health care providers' inadequate salary, high workload and inadequate health workforce, inappropriate infrastructure, lack of training opportunities, unclear division of responsibility, and the presence of strict auditing. In conclusion, ART coverage was below the global average, and key populations were disproportionally less covered with ART in most countries. Huge catastrophic health expenditures were observed. UHC contexts of ART will be improved by reaching people with poor socioeconomic status, delivering appropriate services, establishing a proper health workforce and service stewardship.

High-level dolutegravir resistance can emerge rapidly from few variants and spread by recombination: implications for integrase strand transfer inhibitor salvage therapy

The integrase strand transfer inhibitor (INSTI) dolutegravir is commonly used in combination antiretroviral therapy regimens and retains strong potency even with primary resistance mutations to some other INSTIs. Acquisition of accessory mutations to primary mutations results in significant increases in dolutegravir resistance. Previously, we reported that addition of the secondary mutation T97A can result in rapid treatment failure in individuals with INSTI mutations at positions 140 and 148. Here, we conducted a detailed case study of one of these individuals and find that T97A-containing HIV emerged from a large replicating population from only a few (≤4) viral lineages. When combined with primary INSTI resistance mutations, T97A provides a strong selective advantage; the finding that T97A-containing variants spread by replication and recombination, and persisted for months after discontinuing dolutegravir, has important implications as dolutegravir is rolled out worldwide.

HIV and ART related knowledge among newly diagnosed patients with HIV under the universal-test-and-treat (UTT) policy in Johannesburg, South Africa

South Africa implemented Universal Test & Treat (UTT) guidelines in September 2016. We examine HIV/ART knowledge among newly diagnosed from a prospective study enrolling newly diagnosed HIV-positive adults, under same-day ART policy, at four primary health clinics in Johannesburg, South Africa. We describe factors associated with high HIV/ART related knowledge score among newly diagnosed patients using Poisson regression. We included 652 HIV positive adults (64.1% female; median age 33 years (IQR: 28-39). Overall, 539 (82.7%) patients were classified as having high HIV/ART knowledge, 14.7% medium knowledge and 2.6% had low knowledge. HIV/ART knowledge was mainly associated to high English literacy (aRR 0.9 Medium vs High, 95% CI: 0.8-0.9; aRR 0.7 for Low vs High: 95% CI: 0.6-0.9). However, patients who did not disclose their intentions for HIV test (aRR 0.9, not disclosed intentions vs having disclosed intentions to test, 95% CI: 0.8-0.9), participants who indicated concerns with ART (aRR 0.9 moderate to high vs low concerns, 95% CI: 0.8-0.9) were less likely to have high knowledge. Our results highlight a correlation between English literacy and good knowledge. There is a need to make information more accessible in a non-English language. Addressing this gap is critical in achieving the WHO targets.

Understanding the Reasons for Deferring ART Among Patients Diagnosed Under the Same-Day-ART Policy in Johannesburg, South Africa

We aimed to examine the correlates of antiretroviral therapy (ART) deferral to inform ART demand creation and retention interventions for patients diagnosed with HIV during the Universal Test and Treat (UTT) policy in South Africa. We conducted a cohort study enrolling newly diagnosed HIV-positive adults (≥ 18 years), at four primary healthcare clinics in Johannesburg between October 2017 and August 2018. Patients were interviewed immediately after HIV diagnosis, and ART initiation was determined through medical record review up to six-months post-test. ART deferral was defined as not starting ART six months after HIV diagnosis. Participants who were not on ART six-months post-test were traced and interviewed telephonically to determine reasons for ART deferral. Modified Poisson regression was used to evaluate correlates of six-months ART deferral. We adjusted for baseline demographic and clinical factors. We present crude and adjusted risk ratios (aRR) associated with ART deferral. Overall, 99/652 (15.2%) had deferred ART by six months, 20.5% men and 12.2% women. Baseline predictors of ART deferral were older age at diagnosis (adjusted risk ratio (aRR) 1.5 for 30-39.9 vs 18-29.9 years, 95% confidence intervals (CI): 1.0-2.2), disclosure of intentions to test for HIV (aRR 2.2 non-disclosure vs disclosure to a partner/spouse, 95% CI: 1.4-3.6) and HIV testing history (aRR 1.7 for  > 12 months vs < 12 months/no prior test, 95% CI: 1.0-2.8). Additionally, having a primary house in another country (aRR 2.1 vs current house, 95% CI: 1.4-3.1) and testing alone (RR 4.6 vs partner/spouse support, 95% CI: 1.2-18.3) predicted ART deferral among men. Among the 43/99 six-months interviews, women (71.4%) were more likely to self-report ART initiation than men (RR 0.4, 95% CI: 0.2-0.8) and participants who relocated within SA (RR 2.1 vs not relocated, 95% CI: 1.2-3.5) were more likely to still not be on ART. Under the treat-all ART policy, nearly 15.2% of study participants deferred ART initiation up to six months after the HIV diagnosis. Our analysis highlighted the need to pay particular attention to patients who show little social preparation for HIV testing and mobile populations.

Challenges with tracing patients on antiretroviral therapy who are late for clinic appointments in rural South Africa and recommendations for future practice

Background: It is common practice for HIV programmes to routinely trace patients who are late for a scheduled clinic visit to ensure continued care engagement. In South Africa, patients who are late for a scheduled visit are identified from clinic registers, and called by telephone up to three times by designated clinic staff, with home visits conducted for those who are unreachable by phone. It is important to understand outcomes among late patients in order to have accurate mortality data, identify defaulters to attempt to re-engage them into care, and have accurate estimates of patients still in care for planning purposes.

Objective: We conducted a study to assess whether tracing of HIV patients in clinics in rural north-eastern South Africa was implemented in line with national policies.

Methods: Thirty-three person-day of observations took place during multiple visits to eight facilities between October 2017 and January 2018 during which clinic tracing processes were captured. The facility level implementation processes were compared to the intended tracing process and gaps and challenges were identified.

Results: Challenges to implementing effective tracing procedures fell into three broad categories: i) facility-level barriers, ii) issues relating to data, documentation and record-keeping, and iii) challenges relating to the roles and responsibilities of the different actors in the tracing cascade.

We recommend improving linkages between clinics, improving record-keeping systems, and regular training of community health workers involved in tracing activities. Improved links between clinics would reduce the chance of patients being lost between clinics. Record-keeping systems could be improved through motivating health workers to take ownership of their data and training them on the importance of complete data. Finally, training of community health workers may improve sustained motivation, and improve their ability to respond appropriately to their clients’ needs.

Conclusions: Substantial investment in data infrastructure and healthcare staff training is needed to improve routine tracing.

Health provider perspectives on the implementation of the same-day-ART initiation policy in the Gauteng province of South Africa

Background

In September 2016, South Africa (SA) began implementing the universal-test-and-treat (UTT) policy in hopes of attaining the UNAIDS 90-90-90 targets by 2020. The SA National Department of Health provided a further directive to initiate antiretroviral therapy (ART) on the day of HIV diagnosis in September 2017. We conducted a qualitative study to determine the progress in implementing UTT and examine health providers' perspectives on the implementation of the same-day initiation (SDI) policy, six months after the policy change.

Methods

We conducted in-depth interviews with three professional nurses, and four HIV lay counsellors of five primary health clinics in the Gauteng province, between October and December 2017. In September 2018, we also conducted a focus group discussion with ten professional nurses/clinic managers from ten clinic facilities. The interviews and focus groups covered the adoption and implementation of UTT and SDI policies. Interviews were conducted in English, Sotho or Zulu and audio-recorded with participant consent. Audio-recordings were transcribed verbatim, translated to English and analysed thematically using NVivo 11.

Results

The data indicates inconsistencies across facilities and incongruities between counsellor and nursing provider perspectives regarding the SDI policy implementation. While nurses highlighted the clinical benefits of early ART initiation, they expressed concerns that immediate ART may be overwhelming for some patients, who may be unprepared and likely to disengage from care soon after the initial acceptance of ART. Accordingly, the SDI implementation was slow due to limited patient demand, provider ambivalence to the policy implementations, as well as challenges with infrastructure and human resources. The process for assessing patient readiness was poorly defined by health providers across facilities, inconsistent and counsellor dependent. Providers were also unclear on how to ensure that patients who defer treatment return for ongoing counselling.

Conclusions

Our results highlight important gaps in the drive to achieve the ART initiation target and demonstrate the need for further engagement with health care providers around the implementation of same-day ART initiation, particularly with regards to infrastructural/capacity needs and the management of patient readiness for lifelong ART on the day of HIV diagnosis. Additionally, there is a need for improved promotion of the SDI provision both in health care settings and in media communications to increase patient demand for early and lifelong ART.

Mobility and structural barriers in rural South Africa contribute to loss to follow up from HIV care

Retention in HIV care is crucial to sustaining viral load suppression, and reducing HIV transmission, yet loss to follow-up (LTFU) in South Africa remains substantial. We conducted a mixed methods evaluation in rural South Africa to characterize ART disengagement in neglected rural settings. Using convenience sampling, surveys were completed by 102 PLWH who disengaged from ART (minimum 90 days) and subsequently resumed care. A subset (n = 60) completed individual in-depth interviews. Median duration of ART discontinuation was 9 months (IQR 4-22). Participants had HIV knowledge gaps regarding HIV transmission and increased risk of tuberculosis. The major contributors to LTFU were mobility and structural barriers. PLWH traveled for an urgent family need or employment, and were not able to collect ART while away. Structural barriers included inability to access care, due to lack of financial resources to reach distant clinics. Other factors included dissatisfaction with care, pill fatigue, lack of social support, and stigma. Illness was the major precipitant of returning to care. Mobility and structural barriers impede longitudinal HIV care in rural South Africa, threatening the gains made from expanded ART access. To achieve 90-90-90, future interventions, including emphasis on patient centered care, must address barriers relevant to rural settings.

A Case Study of an Effective and Sustainable Antiretroviral Therapy Program in Rural South Africa

The delivery of high-quality HIV care in rural settings is a global challenge. Despite the successful expansion of antiretroviral therapy (ART) in Africa, viral load (VL) monitoring and ART adherence are poor, especially in rural communities. This article describes a case study of an ART program in the deeply rural Eastern Cape of South Africa. The Zithulele ART Program initiated five innovations over time: (1) establishing district hospital as the logistical hub for all ART care in a rural district, (2) primary care clinic delivery of prepackaged ART and chronic medications for people living with HIV (PLH), (3) establishing central record keeping, (4) incentivizing VL monitoring, and (5) providing hospital-based outpatient care for complex cases. Using a pharmacy database, on-time VL monitoring and viral suppression were evaluated for 882 PLH initiating ART in the Zithulele catchment area in 2013. Among PLH initiating ART, 12.5% (n = 110) were lost to follow-up, 7.7% (n = 68) transferred out of the region, 10.2% (n = 90) left the program and came back at a later date, and 4.0% (n = 35) died. Of the on-treatment population, 82.9% (n = 480/579) had VL testing within 7 months and 92.6% (n = 536/579) by 1 year. Viral suppression was achieved in 85.2% of those tested (n = 457/536), or 78.9% (n = 457/579) overall. The program's VL testing and suppression rates appear about twice as high as national data and data from other rural centers in South Africa, despite fewer resources than other programs. Simple system innovations can ensure high rates of VL testing and suppression, even in rural health facilities.

Feasibility of antiretroviral therapy initiation under the treat-all policy under routine conditions: a prospective cohort study from Eswatini

INTRODUCTION

The World Health Organization recommends the Treat-All policy of immediate antiretroviral therapy (ART) initiation, but questions persist about its feasibility in resource-poor settings. We assessed the feasibility of Treat-All compared with standard of care (SOC) under routine conditions.

METHODS

This prospective cohort study from southern Eswatini followed adults from HIV care enrolment to ART initiation. Between October 2014 and March 2016, Treat-All was offered in one health zone and SOC according to the CD4 350 and 500 cells/mm3 treatment eligibility thresholds in the neighbouring health zone, each of which comprised one secondary and eight primary care facilities. We used Kaplan-Meier estimates, multivariate flexible parametric survival models and standardized survival curves to compare ART initiation between the two interventions.

RESULTS

Of the 1726 (57.3%) patients enrolled under Treat-All and 1287 (42.7%) under SOC, cumulative three-month ART initiation was higher under Treat-All (91%) than SOC (74%; p < 0.001) with a median time to ART of 1 (IQR 0 to 14) and 10 (IQR 2 to 117) days respectively. Under Treat-All, ART initiation was higher in pregnant women (vs. non-pregnant women: adjusted hazard ratio (aHR) 1.96, 95% confidence interval (CI) 1.70 to 2.26), those with secondary education (vs. no formal education: aHR 1.48, 95% CI 1.12 to 1.95), and patients with an HIV-positive diagnosis before care enrolment (aHR 1.22, 95% CI 1.10 to 1.36). ART initiation was lower in patients attending secondary care facilities (aHR 0.64, 95% CI 0.58 to 0.72) and for CD4 351 to 500 when compared with CD4 201 to 350 cells/mm3 (aHR 0.84, 95% CI 0.72 to 1.00). ART initiation varied over time for TB cases, with lower hazard during the first two weeks after HIV care enrolment and higher hazards thereafter. Of patients with advanced HIV disease (n = 1085; 36.0%), crude 3-month ART initiation was similar in both interventions (91% to 92%) although Treat-All initiated patients more quickly during the first month after HIV care enrolment.

CONCLUSIONS

ART initiation was high under Treat-All and without evidence of de-prioritization of patients with advanced HIV disease. Additional studies are needed to understand the long-term impact of Treat-All on patient outcomes.

"If you are here at the clinic, you do not know how many people need help in the community": Perspectives of home-based HIV services from health care workers in rural KwaZulu-Natal, South Africa in the era of universal test-and-treat

Background

Limited engagement in clinic-based care is affecting the HIV response. We explored the field experiences and perceptions of local health care workers regarding home-based strategies as opportunities to improve the cascade of care of people living with HIV in rural South Africa as part of a Universal Test-and-Treat approach.

Methods

In Hlabisa sub-district, home-based HIV services, including rapid HIV testing and counselling, and support for linkage to and retention in clinic-based HIV care, were implemented by health care workers within the ANRS 12249 Treatment-as-Prevention (TasP) trial. From April to July 2016, we conducted a mixed-methods study among health care workers from the TasP trial and from local government clinics, using self-administrated questionnaires (n = 90 in the TasP trial, n = 56 in government clinics), semi-structured interviews (n = 13 in the TasP trial, n = 5 in government clinics) and three focus group discussions (n = 6–10 health care workers of the TasP trial per group). Descriptive statistics were used for quantitative data and qualitative data were analysed thematically.

Results

More than 90% of health care workers assessed home-based testing and support for linkage to care as feasible and acceptable by the population they serve. Many health care workers underlined how home visits could facilitate reaching people who had slipped through the cracks of the clinic-based health care system and encourage them to successfully access care. Health care workers however expressed concerns about the ability of home-based services to answer the HIV care needs of all community members, including people working outside their home during the day or those who fear HIV-related stigmatization. Overall, health care workers encouraged policy-makers to more formally integrate home-based services in the local health system. They promoted reshaping the disease-specific and care-oriented services towards more comprehensive goals.

Conclusion

Because home-based services allow identification of people early during their infection and encourage them to take actions leading to viral suppression, HCWs assessed them as valuable components within the panel of UTT interventions, aiming to reach the 90-90-90 UNAIDS targets, especially in the rural Southern African region.

Trial registration

The registration number of the ANRS 12249 TasP trial on ClinicalTrials.gov is NCT01509508.
