Sinako, a study on HIV competent households in South Africa: a cluster-randomised controlled trial protocol

Including the Household: Individual, Community and Household Factors Affecting Antiretroviral Therapy Adherence After ART Initiation in Cape Town, South Africa

Antiretroviral therapy (ART) adherence is crucial for health outcomes of people living with HIV (PLHIV), influenced by a complex interplay of individual, community, and household factors. This article focuses on the influence of household factors, as well as individual and community factors, on ART adherence among PLHIV in Cape Town who have recently initiated ART. Baseline data for a cluster-randomized controlled trial were collected from 316 PLHIV in 12 districts in Cape Town between 6th May 2021 and 22nd May 2022. Zero-inflated Poisson models, with cluster-adjusted standard errors, were used to analyse the association between individual, household, and community factors and ART adherence measures. At the household-level, household support was associated with both better self-rated adherence (exp(β) = 0.81, z =  - 4.68, p < 0.001) and fewer days when pills were missed (exp(β) = 0.65, z =  - 2.92, p = 0.003). Psychological violence (exp(β) = 1.37, z = 1.97, p = 0.05) and higher household asset scores (exp(β) = 1.29, z =  - 2.83, p = 0.05) were weakly associated with poorer ART adherence. At the individual-level, male gender (exp(β) = 1.37, z = 3.95, p < 0.001) and reinitiating ART (exp(β) = 1.35, z = 3.64, p < 0.001) were associated with worse self-rated ART adherence; higher education levels (exp(β) = 0.30 times, z =  - 3.75, p < 0.001) and better HIV knowledge (exp(β) = 0.28, z =  - 2.83, p = 0.005) were associated with fewer days where pills were missed. At the community-level, community stigma was associated with worse self-rated ART adherence (exp(β) = 1.24, z = 3.01, p = 0.003). When designing interventions to improve ART adherence, household, individual and community factors should all be considered, particularly in addressing gender-based disparities, reducing stigma, tackling violence, and enhancing household support.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

Evidence and gap map report: Social and Behavior Change Communication (SBCC) interventions for strengthening HIV prevention and research among adolescent girls and young women (AGYW) in low- and middle-income countries (LMICs)

Background

Adolescent girls and young women (AGYW), aged 15-24 years, are disproportionately affected by HIV and other sexual and reproductive health (SRH) risks due to varying social, cultural, and economic factors that affect their choices and shape their knowledge, understanding, and practices with regard to their health. Socio-Behavioral Change Communication (SBCC) interventions targeted at strengthening the capabilities of individuals and their networks have supported the demand and uptake of prevention services and participation in biomedical research. However, despite growing global recognition of the domain, high-quality evidence on the effectiveness of SBCC remains scattered. This evidence and gap map (EGM) report characterizes the evidence base on SBCC interventions for strengthening HIV Prevention and Research among AGYW in low- and middle-income countries (LMICs), identifying evidence gaps and outlining the scope of future research and program design.

Objectives

The objectives of the proposed EGM are to: (a) identify and map existing EGMs in the use of diverse SBCC strategies to strengthen the adoption of HIV prevention measures and participation in research among AGYW in LMICs and (b) identify areas where more interventions and evidence are needed to inform the design of future SBCC strategies and programs for AGYW engagement in HIV prevention and research.

Methods

This EGM is based on a comprehensive search of systematic reviews and impact evaluations corresponding to a range of interventions and outcomes-aimed at engaging AGYW in HIV prevention and research - that were published in LMICs from January 2000 to April 2021. Based on guidance for producing a Campbell Collaboration EGM, the intervention and outcome framework was designed in consultation with a group of experts. These interventions were categorized across four broad intervention themes: mass-media, community-based, interpersonal, and Information Communication and Technology (ICT)/Digital Media-based interventions. They were further sub-categorized into 15 intervention categories. Included studies looked at 23 unique behavioral and health outcomes such as knowledge attitude and skills, relationship dynamics, household dynamics, health care services, and health outcomes and research engagement. The EGM is presented as a matrix in which the rows are intervention categories/sub-categories, and the columns are outcome domains/subdomains. Each cell is mapped to an intervention targeted at outcomes. Additional filters like region, country, study design, age group, funding agency, influencers, population group, publication status, study confidence, setting, and year of publication have been added.

Selection Criteria

To be eligible, studies must have tested the effectiveness of SBCC interventions at engaging AGYW in LMICs in HIV prevention and research. The study sample must have consisted of AGYW between the ages of 15-24, as defined by UNAIDS. Both experimental (random assignment) and quasi-experimental studies that included a comparison group were eligible. Relevant outcomes included those at the individual, influencer, and institutional levels, along with those targeting research engagement and prevention-related outcomes.

Results

This EGM comprises 415 impact evaluations and 43 systematic reviews. Interventions like peer-led interactions, counseling, and community dialogues were the most dominant intervention sub-types. Despite increased digital penetration use of media and technology-driven interventions are relatively less studied. Most of the interventions were delivered by peers, health care providers, and educators, largely in school-based settings, and in many cases are part of sex-education curricula. Evidence across geographies was mostly concentrated in Sub-Saharan Africa (70%). Most measured outcomes focused on disease-related knowledge dissemination and enhancing awareness of available prevention options/strategies. These included messaging around consistent condom use, limiting sexual partners, routine testing, and awareness. Very few studies were able to include psychographic, social, and contextual factors influencing AGYW health behaviors and decisions, especially those measuring the impact of social and gender norms, relationship dynamics, and household dynamics-related outcomes. Outcomes related to engagement in the research were least studied.

Conclusion

This EGM highlights that evidence is heavily concentrated within the awareness-intent spectrum of behavior change and gets lean for outcomes situated within the intent-action and the action-habit formation spectrum of the behavior change continuum. Most of the evidence was concentrated on increasing awareness, knowledge, and building risk perception around SRH domains, however, fewer studies focused on strengthening the agency and self-efficacy of individuals. Similarly, evidence on extrinsic factors-such as strengthening social and community norms, relationships, and household dynamics-that determine individual thought and action such as negotiation and life skills were also found to be less populated. Few studies explore the effectiveness of these interventions across diverse AGYW identities, like pregnant women and new mothers, sex workers, and people living with HIV, leading to limited understanding of the use of these interventions across multiple user segments including key influencers such as young men, partners, families, religious leaders, and community elders was relatively low. There is a need for better quality evidence that accounts for the diversity of experiences within these populations to understand what interventions work, for whom, and toward what outcome. Further, the evidence for use of digital and mass-media tools remains poorly populated. Given the increasing penetration of these tools and growing media literacy on one end, with widening gender-based gaps on the other, it is imperative to gather more high-quality evidence on their effectiveness. Timely evidence generation can help leverage these platforms appropriately and enable intervention designs that are responsive to changing communication ecologies of AGYW. SBCC can play a critical role in helping researchers meaningfully engage and collaborate with communities as equal stakeholders, however, this remains poorly evidenced and calls for investigation and investment.

The practice of pilot/feasibility studies in informing the conduct of HIV related clinical trials in sub-Saharan Africa: A scoping review

Introduction

Pilot/feasibility studies represent a fundamental phase of the research process and play a vital role in the preliminary planning of a full size HIV clinical trial. Published HIV clinical trial protocols were reviewed to establish the extent to which the proposed HIV clinical trials are informed by a prior pilot/feasibility study.

Methods

The JBI methodology for scoping reviews was followed. Six databases were systematically searched to identify articles for inclusion.

Results

Thirty two (32) published HIV study protocols were included. Articles were in the English language and were published in the past 10 years (2011-2020). The review results showed that the majority of HIV-related clinical trials in sub-Saharan Africa were not informed by pilot/feasibility studies. The results further indicated that the number of HIV clinical trials informed by a pilot/feasibility study have been on the increase in the 8 years' period since 2012, a trend that indicates positive uptake of pilot studies in HIV related studies. A few select countries (South Africa, Uganda, Zimbabwe, Malawi and Kenya) comprised more than 70% of all clinical trials that were informed by a pilot/feasibility study, conducted in sub Saharan Africa.

Conclusions

Although there is an increasing interest among researchers to integrate pilot/feasibility studies in HIV related research, limited countries in sub-Saharan Africa appear to have embraced this trend. Strategies that can motivate researchers to engage in a culture of incorporating pilot/feasibility studies in HIV related research should be implemented.

A cross-cultural adaptation and validation of a scale to assess illness identity in adults living with a chronic illness in South Africa: a case of HIV

The chronic illness trajectory and its outcomes are well explained by the concept of illness identity; the extent to which ill individuals have integrated their diagnosed chronic illness into their identity or sense of self. The capacity to measure illness identity in people living with HIV (PLHIV) is still relatively unexplored. However, this is potentially useful to help us understand how outcomes for PLHIV could be improved and sustained. This paper aims to explore the cross-cultural adaptation of a Belgian developed Illness Identity Questionnaire (IIQ) and validate the instrument using a sample of South African adults living with HIV. We followed a phased scale adaptation and validation process which included an investigation of conceptual, item, semantic and operational equivalence and also examined the psychometric properties of the IIQ. The concept of illness identity with its four factors; engulfment, rejection, acceptance and enrichment in PLHIV, was found to be relevant within this context. Five items from the original IIQ were excluded from the adapted IIQ due to either semantic insufficiency and/or inadequate measurement equivalence. The mode of administration of the IIQ was changed to accommodate current study participants. The original four factor 25-item model did not fit current data, however, a better contextualized, four-factor, 20-item model was identified and found valid in the current setting. The results showed adequate statistical fit; χ²/d.f. = 1.516, RMSEA = 0.076, SRMR = 0.0893, and CFI = 0.909. Convergent and discriminant validity were also tenable. The cross-cultural adaptation and validation of the IIQ was successful, resulting in the availability of an instrument capable of measuring illness identity in PLHIV in a high HIV prevalence and resource-constrained setting. This therefore addresses the paucity of information and expands on knowledge about illness identity.

Stay-at-Home: The Impact of the COVID-19 Lockdown on Household Functioning and ART Adherence for People Living with HIV in Three Sub-districts of Cape Town, South Africa

In March 2020, the South African government imposed a lockdown to control COVID-19 transmission. Lockdown may affect people living with HIV's (PLWH) antiretroviral therapy (ART) adherence. Data from a cluster randomised control trial was collected from 152 PLWH in Cape Town sub-districts from October 2019-March 2020 when the lockdown halted collection. Subsequently, 83 PLWH were followed-up in June-July 2020. Random effects models were used to analyse: (1) changes between baseline and follow-up and (2) correlates of adherence during lockdown. At follow-up, there was an increase in the odds of being below the poverty line and the odds of experiencing violence decreased. Measures for well-being, household functioning, stigma and HIV competency improved. Violence, depression, food insecurity, and stigma were associated with poorer ART adherence; higher well-being scores were associated with better adherence. During lockdown, governments need to ensure financial support, access to (mental) health services, and services for those experiencing violence.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

Adapting to, integrating and self-managing HIV as a chronic illness: a scoping review protocol

INTRODUCTION

The process of adapting to a life with a chronic illness, is a well-researched phenomenon for a number of common chronic illnesses. The construct, adaptation, embeds the notions of integration of the chronic illness into identity and self-management. Integration precedes self-management and is key to living positively with a chronic illness. Adaptation is an important concept in understanding trajectory and outcomes of living with a chronic illness. Applicability of these concepts to HIV as a chronic illness; when suppressive adherence has been achieved, however, is unknown. Specifically, the adaptation process to living with HIV as a chronic illness, the integration of HIV into identity and the resulting self-management behaviours by adults living with HIV are relatively unexplored. We describe a protocol for a scoping review of adaptation to living with HIV, we structure the enquiry around integration of HIV into identity and self-management and interrogate theories, models and frameworks that have been proposed and studied and we evaluate them for relevance and usefulness in the care and management of HIV.

METHODS AND ANALYSIS

Methods proposed by the Johanna Briggs Institute will be followed. The protocol was drafted using the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews and was registered with the Open Science Framework. MEDLINE, SCOPUS, Cochrane Library, CINHAL and SocINDEX databases will be searched. A search in Social Science Research Network eLibrary and Open Access Theses and Dissertations will gather grey literature and reference lists of included sources will be screened. Study selection process will involve a title and abstract review and full text review, guided by clearly defined inclusion and exclusion criteria.

ETHICS AND DISSEMINATION

Ethical approval is not required because this is a proposed review and collection of data on publicly available materials. The results will be published in a topic relevant journal and presented at related scientific events.

Households in HIV Care: Designing an Intervention to Stimulate HIV Competency in Households in South Africa

Despite the Universal Test and Treat program and widespread antiretroviral treatment rollout, South Africa is still facing HIV prevention and treatment challenges, which are aggravated by human resource shortages in the healthcare sector. Individual- and community-level responses to these HIV-related challenges are increasingly being explored, for example, in community and home-based care. The role of the household as a crucial mediating social level has, however, largely been omitted. This paper outlines the design of an intervention to stimulate the involvement of the household in support for people living with HIV in South Africa. The 6SQuID model guided the intervention development process in four phases: (1) formative research, theory formulation, and a review of the existing literature, (2) integration of the results from the formative research into the "Positive Communication Process" (P2CP model) as a mechanism of change, (3) design of a community-health-worker-led intervention as the way to deliver the change mechanism, and (4) testing and revision of the developed intervention material-called Sinako-in a small-scale pilot study. The Sinako intervention anticipates that the future of chronic HIV care in resource-constrained settings will need to integrate the patient's household into the fight against HIV.
