RESUMEN

BACKGROUND: The COVID-19 pandemic forced governments, multilateral public health organisations and research institutions to undertake research quickly to inform their responses to the pandemic. Most COVID-19-related studies required swift approval, creating ethical and practical challenges for regulatory authorities and researchers. In this paper, we examine the landscape of ethics review processes in Africa during public health emergencies (PHEs). METHODS: We searched four electronic databases (Web of Science, PUBMED, MEDLINE Complete, and CINAHL) to identify articles describing ethics review processes during public health emergencies and/or pandemics. We selected and reviewed those articles that were focused on Africa. We charted the data from the retrieved articles including the authors and year of publication, title, country and disease(s) reference, broad areas of (ethical) consideration, paper type, and approach. RESULTS: Of an initial 4536 records retrieved, we screened the titles and abstracts of 1491 articles, and identified 72 articles for full review. Nine articles were selected for inclusion. Of these nine articles, five referenced West African countries including Liberia, Guinea and Sierra Leone, and experiences linked to the Ebola virus disease. Two articles focused on South Africa and Kenya, while the other two articles discussed more general experiences and pitfalls of ethics review during PHEs in Africa more broadly. We found no articles published on ethics review processes in Africa before the 2014 Ebola outbreak, and only a few before the COVID-19 outbreak. Although guidelines on protocol review and approval processes for PHEs were more frequently discussed after the 2014 Ebola outbreak, these did not focus on Africa specifically. CONCLUSIONS: There is a gap in the literature about ethics review processes and preparedness within Africa during PHEs. This paper underscores the importance of these processes to inform practices that facilitate timely, context-relevant research that adequately recognises and reinforces human dignity within the quest to advance scientific knowledge about diseases. This is important to improve fast responses to PHEs, reduce mortality and morbidity, and enhance the quality of care before, during, and after pandemics.

RESUMEN

Background: Adolescents and young adults living with HIV (AYA) are faced with the challenge of living with a life-long chronic condition. We investigated the influences on the decisions by AYA to disclose their HIV status to family, intimate partners and friends.Methods: Twenty AYA aged between 15 and 24 years were purposely selected through local community-based organisations in eThekwini municipality and uMkhanyakude district in KwaZulu-Natal Province, South Africa. Virtual in-depth interviews were conducted between September 2020 to October 2021 using a topic guide focusing on HIV-status disclosure and the impact of stigma on decision-making capacity. An iterative thematic process was used for analysis.Results: Findings revealed the challenges that AYA experience for disclosure because of stigma and how this impacts their decision-making capacity. Family and friends influenced AYA in processing their discovery of their HIV status offering support needed to manage living with HIV. However, for some AYA disclosing to relatives, friends and intimate partners was difficult because of fears of rejection and recrimination. The act of disclosure was influenced by both internalised and external stigma and the type of relationships and interactions that AYA had with relatives, friends and caregivers.Conclusions: The decision to disclose is challenging for AYA because of the fear of rejection, along with internal and external stigma. The provision of support, whether from family or peers, is important. Enhancing the decision-making capacity of AYA is essential for developing their self-esteem as well as supporting future healthcare choices.

RESUMEN

BACKGROUND: Social isolation and loneliness are associated with living with a chronic condition particularly where stigma is a factor. Our study aimed to examine the lived experience of adolescents living with HIV in relation to isolation because of their diagnosis and consequences of disclosure. Giddens' structuration theory was used as an analytic framework to identify the potential mechanisms underlying adolescents living with HIV's experiences. METHOD: Longitudinal in-depth interviews were conducted with 20 adolescents living with HIV aged 15-24 years with each participant taking part in three interviews (total 60) between September 2020 and October 2021. Thematic analysis was performed using Braun and Clarke's steps for coding and analysing qualitative data and informed by the structuration theory framework. RESULTS: The findings indicated that adolescents living with HIV have agency and make conscious choices about sharing their status. However, these choices are influenced by their experiences in their community. The discrimination and negative judgements they often experience prevent them from disclosing their status. Stigma, discrimination, and psychological distress contribute to the isolation that adolescents and young adults living with HIV experience. The limited disclosure itself can lead to them becoming isolated and lonely. CONCLUSION: The negative experiences which adolescents living with HIV face can have an impact not only on their psychological wellbeing but also on their decision to disclose and seek support. These experiences may lead to social isolation and loneliness, an unintended consequence of their action in protecting themselves from the conditions created by the structures/environment in which they live.

RESUMEN

This study aims to examine the experiences of young migrants and the role of uncertainty in their precarious lives. Drawing on data from individual interviews and a workshop with young migrants aged 16-24 years old in KwaZulu-Natal, South Africa, we use uncertainty as a theoretical lens, to illustrate the ways in which young migrants' experiences provide meaning for them and give them an opportunity to assess, and plan for better opportunities despite the stark outlook. Thematic analysis was used to examine the multidimensionality of socio-spatial identities in young migrants. The findings illustrate how young migrants hustle for opportunities to lead valuable lives in the face of uncertainty. The implications highlight how attending to the complex intersectional nuances of uncertainty can serve as an enabler of aspirations, alongside essential structural factors influencing migration among young people brought up in rural communities. However, in proposing this alternative view of positive uncertainty, the structural violence experienced by these young people should not be overlooked and should be addressed as per their context.

RESUMEN

ABSTRACTYoung migrants in sub-Saharan Africa are particularly vulnerable to HIV-acquisition. Despite this, they are consistently under-served by services, with low uptake and engagement. We adopted a community-based participatory research approach to conduct longitudinal qualitative research among 78 young migrants in South Africa and Uganda. Using repeat in-depth interviews and participatory workshops we sought to identify their specific support needs, and to collaboratively design an intervention appropriate for delivery in their local contexts. Applying a protection-risk conceptual framework, we developed a harm reduction intervention which aims to foster protective factors, and thereby nurture resilience, for youth 'on the move' within high-risk settings. Specifically, by establishing peer supporter networks, offering a 'drop-in' resource centre, and by identifying local adult champions to enable a supportive local environment. Creating this supportive edifice, through an accessible and cohesive peer support network underpinned by effective training, supervision and remuneration, was considered pivotal to nurture solidarity and potentially resilience. This practical example offers insights into how researchers may facilitate the co-design of acceptable, sustainable interventions.

RESUMEN

Background: The impact of school closures due to COVID-19 raised widespread concerns about children's health and well-being. We examine the impact on the sexual health needs of learners in the context of COVID-19 related lockdowns in rural KwaZulu-Natal, South Africa.Methods: In july-November 2020 and August-November 2021 we conducted 24 in-depth interviews and 8 group discussions with teachers and learners from 4 schools, community members and key education stakeholders. All interviews were conducted by telephone. We used a thematic analysis approach and Nvivo 12 software to manage the data.Results: Four main themes related to the COVID-19 pandemic emerged from the data: the sexual and reproductive health (SRH) of learners in the lead-up to the pandemic; the impact of COVID-19 on learners' SRH and wellbeing; the opportunities schools provided to support sexual well-being of learners during the pandemic; and the role of schools in supporting SRH for learners during the pandemic. Learners and stakeholders reported that the SRH of young people was affected by alcohol misuse, poor SRH knowledge and few pathways to link learners with services. Stakeholders working with schools reported that a lack of access to biomedical interventions (e.g., contraception) increased learner pregnancies. Gender-based violence in learners' households was reported to have increased during the COVID-19 pandemic related to loss of income. School closures disrupted the provision of a safe space to provide SRH and HIV-education through Life Orientation lessons and school nurse talks. This loss of a safe space also left learners vulnerable to sexual and physical violence. However, once schools re-opened, daily COVID-19 screening in schools provided the opportunity to identify and support vulnerable children who had other social needs (food and uniforms).Conclusion: The COVID-19 pandemic may have increased SRH needs and vulnerability of school-going children in a high HIV-burden rural setting. School shutdowns reduced the opportunity for schools to provide a vital safe space and information to enhance SRH for adolescents. Schools play a vital health promotion and social protection role.

RESUMEN

Climate change is directly and indirectly linked to human health, including through access to treatment and care. Our systematic review presents a systems understanding of the nexus between drought and antiretroviral therapy (ART) adherence in HIV-positive individuals in the African setting. Narrative synthesis of 111 studies retrieved from Web of Science, PubMed/MEDLINE, and PsycINFO suggests that livelihoods and economic conditions, comorbidities and ART regimens, human mobility, and psychobehavioural dispositions and support systems interact in complex ways in the drought-ART adherence nexus in Africa. Economic and livelihood-related challenges appear to impose the strongest impact on human interactions, actions, and systems that culminate in non-adherence. Indeed, the complex pathways identified by our systems approach emphasise the need for more integrated research approaches to understanding this phenomenon and developing interventions.

RESUMEN

BACKGROUND: Limited research has been conducted on explanations and understandings of biobanking for future genomic research in African contexts with low literacy and limited healthcare access. We report on the findings of a sub-study on participant understanding embedded in a multi-disease community health screening and biobank platform study known as 'Vukuzazi' in rural KwaZulu-Natal, South Africa. METHODS: Semi-structured interviews were conducted with research participants who had been invited to take part in the Vukuzazi study, including both participants and non-participants, and research staff that worked on the study. The interviews were transcribed, and themes were identified from the interview transcripts, manually coded, and thematically analysed. RESULTS: Thirty-nine individuals were interviewed. We found that the research team explained biobanking and future genomic research by describing how hereditary characteristics create similarities among individuals. However, recollection and understanding of this explanation seven months after participation was variable. The large volume of information about the Vukuzazi study objectives and procedures presented a challenge to participant recall. By the time of interviews, some participants recalled rudimentary facts about the genetic aspects of the study, but many expressed little to no interest in genetics and biobanking. CONCLUSION: Participant's understanding of information related to genetics and biobanking provided during the consent process is affected by the volume of information as well as participant's interest (or lack thereof) in the subject matter being discussed. We recommend that future studies undertaking biobanking and genomic research treat explanations of this kind of research to participants as an on-going process of communication between researchers, participants and the community and that explanatory imagery and video graphic storytelling should be incorporated into theses explanations as these have previously been found to facilitate understanding among those with low literacy levels. Studies should also avoid having broader research objectives as this can divert participant's interest and therefore understanding of why their samples are being collected.

RESUMEN

Despite the significant benefits of maternal immunisation, uptake remains low in many parts of the world. In this qualitative study, we aimed to assess the factors that influence pregnant women's decision to engage with maternal immunisation in rural KwaZulu-Natal, South Africa. We conducted in-depth interviews with a total of 28 purposively sampled pregnant women and key informants using semi-structured topic guides. Data analysis was conducted using a modified Health Belief Model framework that included constructs of barriers to action, modifying factors of cue to action and perceived social norms. The findings show that traditional customs and institutional barriers such as low-quality health service delivery, long queues, and distance to the health facilities, immunisation vaccine stockouts and low levels of maternal knowledge influence the choice and decision to engage with maternal immunisation. Understanding health-related behaviours and addressing barriers to care is important in facilitating vaccination uptake. This study contributes to the understanding of maternal immunisation uptake in low-resource settings.

RESUMEN

The 2015 El Niño-triggered drought in Southern Africa caused widespread economic and livelihood disruption in South Africa, imposing multiple physical and health challenges for rural populations including people living with HIV (PLHIV). We examined the economic, social and demographic impacts of drought drawing on 27 in-depth interviews in two cohorts of PLHIV in Hlabisa, uMkhanyakude district, KwaZulu-Natal. Thematic analysis revealed how drought-enforced soil water depletion, dried-up rivers, and dams culminated in a continuum of events such as loss of livestock, reduced agricultural production, and insufficient access to water and food which was understood to indirectly have a negative impact on HIV treatment adherence. This was mediated through disruptions in incomes, livelihoods and food systems, increased risk to general health, forced mobility and exacerbation of contextual vulnerabilities linked to poverty and unemployment. The systems approach, drawn from interview themes, hypothesises the complex pathways of plausible networks of impacts from drought through varying socioeconomic factors, exacerbating longstanding contextual precarity, and ultimately challenging HIV care utilisation. Understanding the multidimensional relationships between climate change, especially drought, and poor HIV care outcomes through the prism of contextual vulnerabilities is vital for shaping policy interventions.

RESUMEN

Covid-19 continues to teach the global community important lessons about preparedness for research and effective action to respond to emerging health threats. We share the COVID-19 experiences of a pre-existing cross-site ethics network-the Global Health Bioethics Network-which brings together researchers and practitioners from Africa, Europe, and Southeast Asia. We describe the network and its members and activities, and the work-related opportunities and challenges we faced over a one-year period during the pandemic. We highlight the value of having strong and long-term empirical ethics networks embedded across diverse research institutions to be able to: 1) identify and share relevant ethics challenges and research questions and ways of 'doing research'; 2) work with key stakeholders to identify appropriate ways to contribute to the emerging health issue response - e.g., through ethics oversight, community engagement, and advisory roles at different levels; and 3) learn from each other and from diverse contexts to advocate for positive change at multiple levels. It is our view that being embedded and long term offers opportunities in terms of deep institutional and contextual knowledge, existing relationships and access to a wide range of stakeholders. Being networked offers opportunities to draw upon a wide range of expertise and perspectives, and to bring together internal and external insights (i.e.drawing on different positionalities). Long term funding means that the people and resources are in place and ready to respond in a timely way. However, many tensions and challenges remain, including difficulties in negotiating power and politics in the roles that researchers and research institutions can and should play in an emergency, and the position of empirical ethics within research programmes. We discuss some of these tensions and challenges and consider the implications for our own and similar networks in future.

RESUMEN

BACKGROUND: There is poor viral load monitoring (VLM) and inadequate management of virological failure in HIV-positive individuals on antiretroviral therapy in rural KwaZulu-Natal, South Africa. This could be contributing to increasing HIV drug resistance in the setting. This study aims to investigate the clinical and process impediments in VLM within the health system and to evaluate a quality improvement package (QIP) to address the identified gaps. The QIP comprises (i) a designated viral load champion responsible for administrative management and triaging of viral load results (ii) technological enhancement of the routine clinic-based Three Interlinked Electronic Register (TIER.Net) to facilitate daily automatic import of viral load results from the National Health Service Laboratory to TIER.Net (iii) development of a dashboard system to support VLM. METHODS/DESIGN: The study will evaluate the effectiveness of the QIP compared to current care for improving VLM and virological suppression using an effectiveness implementation hybrid type 3 design. This will use a cluster-randomised design with the primary healthcare clinics as the unit of randomisation with ten clinics randomised in a 1:1 ratio to either the intervention or control arm. We will enrol 150 HIV-positive individuals who had been on ART for ≥ 12 months from each of the ten clinics (750 in 5 intervention clinics vs. 750 in 5 control clinics) and follow them up for a period of 12 months. The primary outcome is the proportion of all patients who have a viral load (VL) measurement and are virally suppressed (composite outcome) after 12 months of follow up. Secondary outcomes during follow up include proportion of all patients with at least one documented VL in TIER.Net, proportion with VL ≥ 50 copies/mL, proportion with VL ≥ 1000 copies/mL (virological failure) and subsequent switch to second-line ART. DISCUSSION: We aim to provide evidence that a staff-centred quality improvement package, designated viral load monitoring champion, and augmentation of TIER.Net with a dashboard system will improve viral load monitoring and lead to improved virological suppression. TRIAL REGISTRATION: This trial is registered on ClinicalTrials.gov on 8 Oct 2021. Identifier: NCT05071573; https://clinicaltrials.gov/ct2/show/NCT05071573?term=NCT05071573&draw=2&rank=1.

RESUMEN

We examine data from young women and men in South Africa and young female sex workers in Uganda to explore the inequalities and hardships experienced during the COVID-19 pandemic and investigate the opportunities and ability presented to navigate in a virtual world to build an inclusive supportive future for young people on the move. We argue that against the backdrop of a fragile past, young people who see their today disturbed, tomorrow reshaped and their futures interrupted, need support to interact with their social environment and adjust their lives and expectations amidst the changing influences of social forces.

RESUMEN

PURPOSE: We examine the levels of post-trial responsibility ascribed to different stakeholders, following a community-based clinical trial and how the 'responsibility' is understood. METHODS: We employed photovoice, unstructured observations and key informant interviews to gain insights into contexts of access to care following transition to the public health system post trial. We used an inductive narrative analysis to explore experiences and understandings of post-trial access (PTA). RESULTS: In their photovoice stories, many participants expressed a sense of abandonment after the trial. This was viewed as a contributing factor to failing to re-engage with care available in the public health system. This led to the experiences of loss as some trial participants defaulted and died. Research investigators, department of health participants and sponsor agreed that PTA was especially important for communities in resource-limited settings. The government has an obligation towards its citizens while researchers have a responsibility to ensure a smooth transition of patients to public clinics. Sponsors have a responsibility to ensure that the trial is conducted in accordance with the protocol and post-trial agreements are in place and adhered to. Research partnerships among stakeholders were affected by power imbalances making it difficult to negotiate and plan for post-trial care responsibilities. CONCLUSIONS: The research community still struggles with understanding the scope of PTA responsibilities. Power dynamics between public health actors and research sponsors need to be managed to ensure that government involvement is not tokenistic. The responsibility of trial participants and ethics committees needs to be investigated further.

RESUMEN

BACKGROUND: Due to the uncertain disease trajectory and variable rate of progression in chronic obstructive pulmonary disease (COPD), health care professionals (HCPs) are challenged in explaining what the future may hold for patients compared to those with lung cancer (LC). Support and communication of timely information can significantly improve health outcomes. OBJECTIVE: This study sought to identify factors that impact communication and support and recommend ways to improve patients' understanding of living with life-threatening illness. METHODS: Semi-structured interviews with patients with LC (n = 22) and advanced COPD (n = 18), their informal carers (21 LC and 18 COPD) and HCPs (n = 51). Patients were recruited from primary and secondary care in the East of England, UK, during 2010-12. RESULTS: Directness and clarity characterized communication in LC, whereas uncertainty and limited explanations predominated in COPD. Discussions on how the disease might impact on decisions and preferences to be made in the future were less common in COPD. Information for LC patients was mainly from hospital clinicians and any information for COPD patients mainly from primary care clinicians. CONCLUSIONS: The experience of COPD patients could be improved by professionals soon after diagnosis explaining to them the typical pattern of decline in COPD, highlighting the inherent uncertainties about when exacerbations and death may occur. This conversation should lead to planning for the different challenges that the patient and informal carer recognize as most important to them. This contrasts with the 'breaking bad news' conversation that oncologists are highly trained to deliver.


People living with lung cancer (LC) or chronic obstructive pulmonary disease (COPD) have poor health-related quality of life. However, more people with LC receive holistic palliative care (which involves supportive advance care planning) than those with COPD. We interviewed patients with LC or COPD, their informal carers (family/friends who support them) and health care professionals (HCPs) about their experiences and our findings confirmed this: HCPs said the uncertainty of COPD prognosis made starting advance care planning conversations challenging. The level of uncertainty and unpredictability is very different in LC and COPD: the cancer diagnosis is made at a single point in time with mortality immediately on the agenda, while COPD is a chronic condition that develops over many years. We urge clinicians to share this uncertainty with patients and to try to explain and communicate it sooner than later. These conversations should also continue as a recognized part of ongoing care so that COPD patients can benefit from understanding the uncertainties they are dealing and living with. LC and COPD should be approached differently to meet patients' condition-specific needs in order that the existing disparity in holistic care can be remedied.

RESUMEN

BACKGROUND: In low- and middle-income settings, obtaining informed consent for biobanking may be complicated by socio-economic vulnerability and context-specific power dynamics. We explored participants experiences and perceptions of the research objectives in a community-based multidisease screening and biospecimen collection platform in rural KwaZulu-Natal, South Africa. METHODS: We undertook semi-structured in-depth interviews to assess participant understanding of the informed consent, research objectives and motivation for participation. RESULTS: Thirty-nine people participated (individuals who participated in screening/biospecimen collection and those who did not and members of the research team). Some participants said they understood the information shared with them. Some said they participated due to the perceived benefits of the reimbursement and convenience of free healthcare. Most who did not participate said it was due to logistical rather than ethical concerns. None of the participants recalled aspects of biobanking and genetics from the consent process. CONCLUSIONS: Although most people understood the study objectives, we observed challenges to identifying language appropriate to explain biobanking and genetic testing to our target population. Engagement with communities to adopt contextually relevant terminologies that participants can understand is crucial. Researchers need to be mindful of the impact of communities' socio-economic status and how compensation can be potentially coercive.

RESUMEN

OBJECTIVES: We evaluated whether implementation of lockdown orders in South Africa affected ambulatory clinic visitation in rural Kwa-Zulu Natal (KZN). DESIGN: Observational cohort SETTING: Data were analysed from 11 primary healthcare clinics in northern KZN. PARTICIPANTS: A total of 46 523 individuals made 89 476 clinic visits during the observation period. EXPOSURE OF INTEREST: We conducted an interrupted time series analysis to estimate changes in clinic visitation with a focus on transitions from the prelockdown to the level 5, 4 and 3 lockdown periods. OUTCOME MEASURES: Daily clinic visitation at ambulatory clinics. In stratified analyses, we assessed visitation for the following subcategories: child health, perinatal care and family planning, HIV services, non-communicable diseases and by age and sex strata. RESULTS: We found no change in total clinic visits/clinic/day at the time of implementation of the level 5 lockdown (change from 90.3 to 84.6 mean visits/clinic/day, 95% CI -16.5 to 3.1), or at the transitions to less stringent level 4 and 3 lockdown levels. We did detect a >50% reduction in child healthcare visits at the start of the level 5 lockdown from 11.9 to 4.7 visits/day (-7.1 visits/clinic/day, 95% CI -8.9 to 5.3), both for children aged <1 year and 1-5 years, with a gradual return to prelockdown within 3 months after the first lockdown measure. In contrast, we found no drop in clinic visitation in adults at the start of the level 5 lockdown, or related to HIV care (from 37.5 to 45.6, 8.0 visits/clinic/day, 95% CI 2.1 to 13.8). CONCLUSIONS: In rural KZN, we identified a significant, although temporary, reduction in child healthcare visitation but general resilience of adult ambulatory care provision during the first 4 months of the lockdown. Future work should explore the impacts of the circulating epidemic on primary care provision and long-term impacts of reduced child visitation on outcomes in the region.

RESUMEN

A coordinated system of disease surveillance will be critical to effectively control the coronavirus disease 2019 (Covid-19) pandemic. Such systems enable rapid detection and mapping of epidemics and inform allocation of scarce prevention and intervention resources. Although many lower- and middle-income settings lack infrastructure for optimal disease surveillance, health and demographic surveillance systems (HDSS) provide a unique opportunity for epidemic monitoring. This protocol describes a surveillance program at the Africa Health Research Institute's Population Intervention Platform site in northern KwaZulu-Natal. The program leverages a longstanding HDSS in a rural, resource-limited setting with very high prevalence of HIV and tuberculosis to perform Covid-19 surveillance. Our primary aims include: describing the epidemiology of the Covid-19 epidemic in rural KwaZulu-Natal; determining the impact of the Covid-19 outbreak and non-pharmaceutical control interventions (NPI) on behaviour and wellbeing; determining the impact of HIV and tuberculosis on Covid-19 susceptibility; and using collected data to support the local public-sector health response. The program involves telephone-based interviews with over 20,000 households every four months, plus a sub-study calling 750 households every two weeks. Each call asks a household representative how the epidemic and NPI are affecting the household and conducts a Covid-19 risk screen for all resident members. Any individuals screening positive are invited to a clinical screen, potential test and referral to necessary care - conducted in-person near their home following careful risk minimization procedures. In this protocol we report the details of our cohort design, questionnaires, data and reporting structures, and standard operating procedures in hopes that our project can inform similar efforts elsewhere.
