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

The impact of homelessness and housing insecurity on HIV

Homelessness is a global problem with wide-ranging causes and contexts. People experiencing homelessness and unstable housing (HUH) are disproportionately affected by HIV and face worse treatment outcomes than those with stable housing due to multiple complex barriers to care. Even in settings with universal health coverage, access to HIV prevention and treatment services remains insufficient for people experiencing HUH. Health system barriers-such as difficult-to-navigate, fragmented care systems and the mistreatment faced in health-care settings-hinder the engagement of this population in HIV care. Tailored service delivery models, including low-barrier care, mobile and street-based care, and long-acting antiretroviral medications for prevention and treatment, show promise in addressing these barriers and improving HIV outcomes among people experiencing HUH. Future research should prioritise high-quality studies of differentiated service delivery, implementation science to optimise prevention and care programmes for this population in varied settings, and expanded access to long-acting pre-exposure prophylaxis and antiretroviral therapy, particularly in low-income and middle-income countries.

Transforming HIV prevention: the promise of long-acting preexposure prophylaxis in high HIV burden settings

PURPOSE OF REVIEW

Recent research on efficacy and safety of long-acting preexposure prophylaxis (PrEP) holds the promise to transform HIV prevention in high HIV burden settings. We review emerging findings regarding early end-user acceptability of long-acting PrEP modalities, feasibility of integrating long-acting PrEP into health systems, and considerations regarding drug resistance and cost.

RECENT FINDINGS

Long-acting PrEP, particularly injectables, was found to be highly acceptable among individuals across key populations in high HIV burden settings. Concerns around use of long-acting PrEP highlight the importance of choice and ability to switch methods. Existing provider-level barriers to oral PrEP implementation (e.g., overburdened staff, training gaps) may impact long-acting PrEP rollout - however, utilization of PrEP implementation strategies such as task-shifting, timely PrEP training for all providers, differentiated service delivery, and integration with sexual health services, may mitigate barriers. Studies modeling injectable PrEP scale-up demonstrate substantial benefits in HIV mortality reduction, outweighing risks of increased integrase inhibitor resistance, but also highlight the urgency of pricing long-acting PrEP to ensure access and affordability.

SUMMARY

Long-acting PrEP could be a game changer in HIV prevention in high burden settings. There is an urgent need for rapid scale production and price reductions to ensure access in high HIV burden settings. Implementation strategies are needed to address individual and provider-level barriers.

People and sites as community resources for preventing and managing chronic health conditions: A conceptual analysis

The prevention and management of chronic non-communicable diseases (NCDs) require community-based efforts-especially as their burden grows, and recognition of the need for engaging diverse stakeholders in care grows. The aim of this conceptual analysis was to categorise existing community resources (people and sites) used to support such efforts, the mechanisms by which they work, and the conditions that constrain their effectiveness. We developed an initial framework for categorising community resources. We then used a sample of the literature- 24 studies from 12 countries-to refine and enrich the framework. We identified seven categories of sites ('where': House, Meeting place, Community health centre, Primary health care centre, Mobile clinic, Pharmacy, and Hospital) and ten categories of people ('who': Community Health Worker, Nurse/Midwife, Health educator, Physician, Primary Health Care Worker, Peer Group, Navigator, Pharmacist, Cultural Advisor, Family caregiver). We identified eight mechanisms through which those resources improve NCD prevention and management: Context specific engagement, Personalised and integrated care, Community health worker led knowledge dissemination, Social support through family and/or friends, Extending the reach of the health system, Social support through peer groups, Task shifting, and Training of health workforce. We identified two broad categories of constraints on these mechanisms: (i) health system barriers such as inadequate workforce, training, coordination and engagement; and (ii) socio-economic, political, and cultural barriers to care. The conceptual categories (of people and sites as resources, the mechanisms through which they work and the contextual constraints on their effectiveness) identified in this analysis may be useful in further analysing current approaches in NCD efforts using community resources, in informing the development of community-based efforts, and in exploring the commonalities and transferable insights between different locations or settings around the world and between different efforts to prevent and manage NCDs within communities.

The impact of persistent precarity on patients' capacity to manage their treatment burden: A comparative qualitative study between urban and rural patients with multimorbidity in South Africa

Background

People living with multimorbidity in low-and middle-income countries (LMICs) experience a high workload trying to meet the demands of self-management. In an unequal society like South Africa, many people face continuous economic uncertainty, which can impact on their capacity to manage their illnesses and lead to poor health outcomes. Using precariousness - the real and perceived impact of uncertainty - as a lens, this paper aims to identify, characterise, and understand the workload and capacity associated with self-management amongst people with multimorbidity living in precarious circumstances in urban and rural South Africa.

Methods

We conducted qualitative semi-structured interviews with 30 patients with HIV and co-morbidities between February and April 2021. Patients were attending public clinics in Cape Town (Western Cape) and Bulungula (Eastern Cape). Interviews were transcribed and data analysed using qualitative framework analysis. Burden of Treatment Theory (BoTT) and the Cumulative Complexity Model (CuCoM) were used as theoretical lenses through which to conceptualise the data.

Results

People with multimorbidity in rural and urban South Africa experienced multi-faceted precariousness, including financial and housing insecurity, dangerous living circumstances and exposure to violence. Women felt unsafe in their communities and sometimes their homes, whilst men struggled with substance use and a lack of social support. Older patients relied on small income grants often shared with others, whilst younger patients struggled to find stable employment and combine self-management with family responsibilities. Precariousness impacted access to health services and information and peoples' ability to buy healthy foods and out-of-pocket medication, thus increasing their treatment burden and reducing their capacity.

Conclusion

This study highlights that precariousness reduces the capacity and increases treatment burden for patients with multimorbidity in low-income settings in South Africa. Precariousness is both accumulative and cyclic, as financial insecurity impacts every aspect of peoples' daily lives. Findings emphasise that current models examining treatment burden need to be adapted to accommodate patients' experiences in low-income settings and address cumulative precariousness. Understanding treatment burden and capacity for patients in LMICs is a crucial first step to redesign health systems which aim to improve self-management and offer comprehensive person-centred care.

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.

Using qualitative study designs to understand treatment burden and capacity for self-care among patients with HIV/NCD multimorbidity in South Africa: A methods paper

Background

Low- and middle-income countries (LMICs), including South Africa, are currently experiencing multiple epidemics: HIV and the rising burden of non-communicable diseases (NCDs), leading to different patterns of multimorbidity (the occurrence of two or more chronic conditions) than experienced in high income settings. These adversely affect health outcomes, increase patients' perceived burden of treatment, and impact the workload of self-management. This paper outlines the methods used in a qualitative study exploring burden of treatment among people living with HIV/NCD multimorbidity in South Africa.

Methods

We undertook a comparative qualitative study to examine the interaction between individuals' treatment burden (self-management workload) and their capacity to take on this workload, using the dual lenses of Burden of Treatment Theory (BoTT) and Cumulative Complexity Model (CuCoM) to aid conceptualisation of the data. We interviewed 30 people with multimorbidity and 16 carers in rural Eastern Cape and urban Cape Town between February-April 2021. Data was analysed through framework analysis.

Findings

This paper discusses the methodological procedures considered when conducting qualitative research among people with multimorbidity in low-income settings in South Africa. We highlight the decisions made when developing the research design, recruiting participants, and selecting field-sites. We also explore data analysis processes and reflect on the positionality of the research project and researchers.

Conclusion

This paper illustrates the decision-making processes conducting this qualitative research and may be helpful in informing future research aiming to qualitatively investigate treatment burden among patients in LMICs.

HIV testing and linkage to ART following secondary distribution of HIV self-test kits to male partners of women living with HIV: a pilot randomized control trial in Mpumalanga, South Africa

INTRODUCTION

South African men are underrepresented in HIV testing and treatment services. Secondary distribution of oral HIV self-test (HIVST) kits by women living with HIV (WLHIV) to their male partners (i.e. index partner HIVST) may increase men's testing and treatment but has been understudied.

METHODS

Between March and July 2021, we evaluated the effectiveness of index partner HIVST versus the standard of care (SOC) (invitations for men's facility-based testing) on men's testing in a 1:1 randomized control trial. Eligibility criteria included: WLHIV; ≥18 years of age; attending one of four high-density rural clinics; have a working cell phone; and self-reported having a primary male partner of unknown serostatus. The primary outcome was the proportion of WLHIV reporting that her partner tested for HIV within 3 months after enrolment.

RESULTS

We enrolled 180 WLHIV and 176 completed an endline survey (mean age = 35 years, 15% pregnant, 47% unmarried or non-cohabiting). In the HIVST arm, 78% of male partners were reported to have tested for HIV versus 55% in SOC (RR = 1.41; 95% CI = 1.14-1.76). In the HIVST arm, nine men were reactive with HIVST (14% positivity), six were confirmed HIV positive with standard testing (67%) and all of those started antiretroviral therapy (ART), and four HIV-negative men started pre-exposure prophylaxis (PrEP) (5%). In SOC, six men were diagnosed with HIV (12% positivity), 100% started ART and seven HIV-negative men started PrEP (16%). One case of verbal intimate partner violence was reported in the HIVST arm.

CONCLUSIONS

Secondary distribution of HIVST to partners of WLHIV was acceptable and effective for improving HIV testing among men in rural South Africa in our pilot study. Interventions are needed to link reactive HIVST users to confirmatory testing and ART.
