Health by the people, again? The lost lessons of Alma-Ata in a community health worker programme in Zambia

National community health worker (CHW) programmes were central to the vision of primary health care that emerged from the Alma-Ata declaration of 1978. CHWs were identified as agents who could offer basic medical treatment and promote community participation and empowerment. Despite the ambitions of this era, many national CHW programmes were neglected, starved of funding, or discontinued in the decades that followed. These programmes were difficult to sustain in a context of rising debt and structural adjustment, but they also suffered due to poor implementation and a lack of clarity about the role and identity of CHWs. Nevertheless, national CHW programmes have returned to the policy agenda in the past fifteen years and key figures and organisations within global health have begun to argue that they offer a way of strengthening health systems and achieving universal health coverage (UHC). Based on ethnographic research conducted between 2019 and 2020, this article examines a new national CHW programme that has been introduced in Zambia. However, as I show in this article, Zambia's new CHW programme has suffered from many of the same key problems that affected the programmes of the Alma-Ata era: insufficient funding, poor implementation, and a lack of clarity about the role of CHWs. This article shows how these mistakes have been repeated and asks why the lessons of the Alma-Ata era have been lost. Three central problems are identified: national CHW programmes continue to be underfunded and regarded as a "cheap" solution; global health organisations and actors today prioritise technical and quantitative approaches when they design and implement these programmes and therefore overlook the historical experiences and qualitative research of the past thirty years; and, finally, policymakers continue to gloss over the tensions and contradictions within the idea of the "community health worker" itself, creating unclear and unrealistic expectations for CHWs.

Lung cancer awareness training experiences of community health workers in KwaZulu-Natal, South Africa

BACKGROUND

Lung cancer is the leading cause of cancer mortality worldwide. Awareness interventions in the developing world remain scarce. Community health workers (CHWs) are a critical component towards ensuring efficient delivery of healthcare services in low- and middle-income countries.

AIM

This study explored the experiences of CHWs of their training as lung cancer awareness intervention implementers.

SETTING

The study was conducted in a resource-poor setting, with CHWs from previously disadvantaged communities.

METHODS

On the last day of training, 10 CHWs were requested to voluntarily participate in a focus group discussion regarding their experiences of the training, utilising a discussion guide.

RESULTS

The participants expressed positive experiences with the training. They cited the amenable and conducive learning environment established by the facilitator. The participants felt empowered through the newly acquired knowledge and wanted to help their communities. However, some participants expressed a desire to have other forms of learning incorporated in future training. The participants were also cognisant of existing gaps in their own knowledge that could be elaborated upon in preparation for potential questions by the community. Some participants confirmed their role as agents of change.

CONCLUSION

The authors propose large-scale intervention studies of lung cancer awareness utilising the CHW programme to gather conclusive evidence regarding their effectiveness at a community level.Contribution: This article provides insight into the training of community health workers on lung cancer awareness and future research on the integration of the intervention into already existing programmes.

Implementation of a task-shared psychosocial intervention for perinatal depression in South Africa: A grounded theory process evaluation

Perinatal depression carries significant levels of disability for both women and their infants, but there is a large treatment gap for this condition in low and middle-income countries (LMICs). To address this gap, task-sharing using community health workers (CHWs) to provide psychosocial interventions for perinatal depression is increasingly common. Many of these interventions have shown significant positive effects on maternal mood, however not all have done so. This study used data from a task-shared psychosocial intervention for perinatal depression in Cape Town, South Africa, the 'Africa Focus on Intervention Research for Mental Health' (AFFIRM-SA) randomised controlled trial (RCT). It aimed to examine the processes that occurred within the delivery of the counselling intervention, and to use these findings to provide recommendations for psychosocial task sharing in LMICs. A grounded theory analysis was conducted of 234 counselling session transcripts from 39 randomly selected participants from the RCT. This revealed that the effectiveness of the intervention was compromised by the negative influence of participants' socio-economic context, and by counselling strategies that did not align with what was intended in the counselling manual. Despite this, participants provided spontaneous accounts of improvement in mood and cognition, and reasons for these improvements, interpreted as elements that were therapeutically effective for them. Most of these elements aligned with previously identified 'common elements' of therapy. Recommendations for future research and practice include conducting participatory formative research, using an iterative and responsive research design informed by implementation science, incorporating contextually appropriate strategies in interventions such as addressing social determinants of mental health, conducting intensive training and supervision, adopting a staged approach to managing depression, and using common elements of therapy as the basis for psychosocial interventions.

‘I Certainly Wasn't as Patient-Centred’

This article explores how a group of paramedics were cross-trained as community health workers (CHWs) in Indiana. Cross-training paramedics as CHWs provided a foundation to better understand the social issues that occur outside of the hospital and clinic, thereby enabling further empathy among paramedics and seeking means to connect patients to other health and social services agencies. I detail how earning a certification as a CHW shifted the mindset of the paramedics and their approach toward caregiving. Ultimately, I argue how cross-training healthcare professionals can further expand the general awareness of CHWs and possible opportunities for employment. However, steps must be taken to ensure that reducing the CHW model to a cross-training opportunity will not minimise the impacts of hiring a full-time CHW.

Conceptualising the Factors Influencing Community Health Workers’ Preparedness for ICT Implementation: A Systematised Scoping Review

Background: Globally, community health workers (CHW) are increasingly viewed as an integral part of the health system as opposed to simply being an extension of it. Given this view, most low- or middle-income countries (LMICs) have refocused their efforts on reorganising CHW initiatives to maximise their impact. The ongoing endeavours to augment the practice of community health workers using technological solutions are characterised by as many challenges as opportunities. In low- and middle-income countries, including South Africa, information and communication technology (ICT) has become a promising development in the enhancement of the equitable coverage of health services by community health workers. However, there has not been a wide-scale implementation and adoption of ICT; most technology initiatives fail to scale up during the implementation stage, which is attributable to human and context-related factors. Although there has been an effort to develop solutions to address ICT infrastructure and technical barriers, conceptualising an evidence-based understanding of the contextual and user-related factors that influence the efficacy of technology adoption by CHWs within their multidimensional system remains critical. Objective: The purpose of the study is to conceptualise the social factors to consider when implementing a bespoke ICT solution suited to the specific demands of CHWs in primary healthcare in developing contexts, with a particular focus on the South African context. Methodology: The methodology involves synthesizing, extracting, and consolidating the findings of a systematised scoping review into concepts and factors. The review adapts Arksey and O’Malley’s scoping review approach to the study and incorporates 59 relevant articles. Results: Although the knowledge base on CHWs is extensive, there is a considerable gap in addressing structural challenges within the community system, which contributes significantly to the overall performance of CHW programs. Factors promoting policy adaptations, common practice within the health system, CHW competencies, a community’s development in terms of knowledge and economic advancement, safety and security, the environment, and the socio-cultural context all play a significant role in facilitating or impeding the success of health interventions from the individual to the national level. Conclusions: Within several practical limitations, the study shows that despite the efforts of various developing countries to promote technology adoption, the barriers to ICT adoption outweigh the benefits gained in developing countries. The paper argues that addressing these challenges before and during implementation is critical. The authors conclude with some essential concerns about assisting CHWs towards realising the desired health outcomes through ICT.

The building blocks of community health systems: a systems framework for the design, implementation and evaluation of iCCM programs and community-based interventions

Introduction

Almost all sub-Saharan African countries have adopted some form of integrated community case management (iCCM) to reduce child mortality, a strategy targeting common childhood diseases in hard-to-reach communities. These programs are complex, maintain diverse implementation typologies and involve many components that can influence the potential success of a program or its ability to effectively perform at scale. While tools and methods exist to support the design and implementation of iCCM and measure its progress, these may not holistically consider some of its key components, which can include program structure, setting context and the interplay between community, human resources, program inputs and health system processes.

Methods

We propose a Global South-driven, systems-based framework that aims to capture these different elements and expand on the fundamental domains of iCCM program implementation. We conducted a content analysis developing a code frame based on iCCM literature, a review of policy documents and discussions with key informants. The framework development was guided by a combination of health systems conceptual frameworks and iCCM indices.

Results

The resulting framework yielded 10 thematic domains comprising 106 categories. These are complemented by a catalogue of critical questions that program designers, implementers and evaluators can ask at various stages of program development to stimulate meaningful discussion and explore the potential implications of implementation in decentralised settings.

Conclusion

The iCCM Systems Framework proposed here aims to complement existing intervention benchmarks and indicators by expanding the scope and depth of the thematic components that comprise it. Its elements can also be adapted for other complex community interventions. While not exhaustive, the framework is intended to highlight the many forces involved in iCCM to help managers better harmonise the organisation and evaluation of their programs and examine their interactions within the larger health system.

Village health workers as health diplomats: negotiating health and study participation in a malaria elimination trial in The Gambia

Background

Although many success stories exist of Village Health Workers (VHWs) improving primary health care, critiques remain about the medicalisation of their roles in disease-specific interventions. VHWs are placed at the bottom of the health system hierarchy as cheap and low-skilled volunteers, irrespective of their highly valued social and political status within communities. In this paper, we shed light on the political role VHWs play and investigate how this shapes their social and medical roles, including their influence on community participation.

Method

The study was carried out within the context of a malaria elimination trial implemented in rural villages in the North Bank of The Gambia between 2016 and 2018. The trial aimed to reduce malaria prevalence by treating malaria index cases and their potentially asymptomatic compound members, in which VHWs took an active role advocating their community and the intervention, mobilising the population, and distributing antimalarial drugs. Mixed-methods research was used to collect and analyse data through qualitative interviews, group discussions, observations, and quantitative surveys.

Results and discussion

We explored the emic logic of participation in a malaria elimination trial and found that VHWs played a pivotal role in representing their community and negotiating with the Medical Research Council to bring benefits (e.g. biomedical care service) to the community. We highlight this representative role of VHWs as ‘health diplomats’, valued and appreciated by community members, and potentially increasing community participation in the trial. We argue that VHWs aspire to be politically present and be part of the key decision-makers in the community through their health diplomat role.

Conclusion

It is thus likely that in the context of rural Gambia, supporting VHWs beyond medical roles, in their social and political roles, would contribute to the improved performance of VHWs and to enhanced community participation in activities the community perceive as beneficial.

Balancing roles and blurring boundaries: Community health workers' experiences of navigating the crossroads between personal and professional life in rural South Africa

As demand for health services grows, task-shifting to lay health workers has become an attractive solution to address shortages in human resources. Community health workers (CHWs), particularly in low-resource settings, play critical roles in promoting equitable healthcare among underserved populations. However, CHWs often shoulder additional burdens as members of the same communities in which they work. We examined the experiences of a group of CHWs called Mentor Mothers (MMs) working in a maternal and child health programme, navigating the crossroads between personal and professional life in the rural Eastern Cape, South Africa. Semi-structured qualitative interviews (n = 10) were conducted by an experienced isiXhosa research assistant, asking MMs questions about their experiences working in their own communities, and documenting benefits and challenges. Interviews were transcribed and translated into English and thematically coded. Emergent themes include balancing roles (positive, affirming aspects of the role) and blurring boundaries (challenges navigating between professional and personal obligations). While many MMs described empowering clients to seek care and drawing strength from being seen as a respected health worker, others spoke about difficulties in adequately addressing clients' needs, and additional burdens they adopted in their personal lives related to the role. We discuss the implications of these findings, on an immediate level (equipping CHWs with self-care and boundary-setting skills), and an intermediate level (introducing opportunities for structured debriefings and emphasising supportive supervision). We also argue that, at a conceptual level, CHW programmes should provide avenues for professionalisation and invest more up-front in their workforce selection, training and support.

The family context of ASHA and Anganwadi work in rural Rajasthan: Gender and labour in CHW programmes

Across the literature on CHWs globally, the role of CHWs' families remains largely unexplored. This article focuses on ASHAs and Anganwadi Workers in a town in rural Rajasthan, India. We interviewed all twenty ASHAs and Anganwadi Workers in this town, and ten of their families; we also conducted participant observation in Anganwadi Centers, health centres, and family settings. ASHA and Anganwadi work was in high demand, despite being low paying, because of an overall lack of jobs for educated women. Every aspect of CHW work, from recruitment to selection to training to the number of hours spent on the job, was heavily determined by families. Women's mobility, income, and workload was tied up in family structures. ASHA and Anganwadi Work increased the mobility and autonomy of the women who held those jobs in significant ways. But mostly, women stayed in these extremely low paying jobs because they and their families hoped that one day they would become permanent jobs with salaries and benefits. By providing honourable work, and keeping the idea of permanent employment in view but always just out of reach, the ASHA and Anganwadi programmes both exploited and strengthened gendered inequalities in the rural Rajasthani labour market.

The anthropology of health systems: A history and review

Ethnographies of health systems are a theoretically rich and rapidly growing area within medical anthropology. Critical ethnographic work dating back to the 1950s has taken policymakers and health staff as points of entry into the power structures that run through the global health enterprise. In the last decade, there has been a surge of ethnographic work on health systems. We conceptualize the anthropology of health systems as a field; review the history of this body of knowledge; and outline emergent literatures on policymaking, HIV, hospitals, Community Health Workers, health markets, pharmaceuticals, and metrics. High-quality ethnographic work is an excellent way to understand the complex systems that shape health outcomes, and provides a critical vantage point for thinking about global health policy and systems. As theory in this space develops and deepens, we argue that anthropologists should look beyond the discipline to think through what their work does and why it matters.

Community-based health workers implementing universal access to HIV testing and treatment: lessons from South Africa and Zambia-HPTN 071 (PopART)

The global expansion of HIV testing, prevention and treatment services is necessary to achieve HIV epidemic control and promote individual and population health benefits for people living with HIV (PLHIV) in sub-Saharan Africa. Community-based health workers (CHWs) could play a key role in supporting implementation at scale. In the HPTN 071 (PopART) trial in Zambia and South Africa, a cadre of 737 study-specific CHWs, working closely with government-employed CHW, were deployed to deliver a ‘universal’ door-to-door HIV prevention package, including an annual offer of HIV testing and referral services for all households in 14 study communities. We conducted a process evaluation using qualitative and quantitative data collected during the trial (2013–2018) to document the implementation of the CHW intervention in practice. We focused on the recruitment, retention, training and support of CHWs, as they delivered study-specific services. We then used these descriptions to: (i) analyse the fidelity to design of the delivery of the intervention package, and (ii) suggest key insights for the transferability of the intervention to other settings. The data included baseline quantitative data collected with the study-specific CHWs (2014–2018); and qualitative data from key informant interviews with study management (n = 91), observations of CHW training events (n = 12) and annual observations of and group discussions (GD) with intervention staff (n = 68). We show that it was feasible for newly recruited CHWs to implement the PopART intervention with good fidelity, supporting the interpretation of the trial outcome findings. This was despite some challenges in managing service quality and CHW retention in the early years of the programme. We suggest that by prioritizing the adoption of key elements of the in-home HIV services delivery intervention model—including training, emotional support to workers, monitoring and appropriate remuneration for CHWs—these services could be successfully transferred to new settings.

Emerging from the Shadows: Intrinsic and Extrinsic Factors Facing Community Health Workers in Western Cape, South Africa

Community health workers (CHWs) have been identified as a key component of the health workforce in South Africa. However, the efficacy of CHW programs continues to be limited by a poor understanding of facilitators and barriers to CHW engagement. This study explores intrinsic and extrinsic factors that CHWs face. We conducted in-depth interviews with 20 CHWs in order to understand the challenges they may face as they implement their duties linked to the primary health care strategy in the Western Cape, South Africa. All interviews were audiotaped, transcribed verbatim, coded and analyzed using NVivo 12. Drawing on narratives of CHWs, we illustrate the complex issues surrounding CHW outreach in poor rural communities. The CHWs identified five key areas of challenges with respect to personal health, gender issues, poor community understanding of CHWs roles, environmental challenges and lack of patient adherence. These all hinder the ability of CHWs to meet their personal and familial needs, as well as those of the community members they support. There is a need to address the intrinsic needs of CHWs in order to ensure their emotional and physical well-being, as well as a need to create an awareness of the roles of CHWs.

'A poverty in understanding': Assessing the structural challenges experienced by community health workers and their clients

Community health workers (CHWs) are crucial intermediaries between marginalised populations and health and social services. Among their unique repertoire of services includes their commitment to advocacy, a crucial skill that aids clients in addressing the social determinants of health that deleteriously affect their wellbeing. However, a plethora of structural barriers encountered by their clients complicates the caregiving of these workers. Drawing on data from a year-long ethnographic research project situated in Indiana, I analyse the diverse structural challenges experienced by these workers and their clients and assess the parallels encountered by CHWs at the global scale. Among the key barriers encountered by CHWs included difficulty in accessing resources for clients, lack of effective public transportation, barriers within the professional workforce, and the overarching negative impact of structural violence on client motivation. In spite of these issues, CHWs can positively address these barriers through a wider adoption of a structural competency approach, which further elucidates and addresses the harmful effects of structural violence.

The trouble with difference: Challenging and reproducing inequality in a biomedical HIV research community engagement process

Community engagement in biomedical trials is to ensure ethical conduct in research, yet it has been criticised regarding power and exploitation of vulnerable communities where trials take place. This makes community engagement processes complex. We report on one example of how the global politics of biomedical research and local issues of contemporary politics and identities intertwine in a community engagement process. These issues emerged during observations in staff training at a biomedical HIV prevention trial centre in South Africa from September to November 2015. Within the practices of the training sessions, the sessions had an unintended and not explicitly discussed purpose, termed the hidden project of creating a safe space for participants to discuss issues of difference. Examples are culture and greeting practices, culture and respect and the politics of language. Creating a space during training sessions where issues of power may be discussed is a prime example of community engagement. Engagement includes creating the space to discuss differences and collaborative bases. Processes of meaningful community stakeholder engagement, as illustrated by the training sessions, may contribute to combination prevention of HIV by promoting the integration of behavioural, sociocultural and biomedical efforts, and by a more developed understanding of power.

Does volunteer community health work empower women? Evidence from Ethiopia’s Women’s Development Army

Of the millions of Community Health Workers (CHWs) serving their communities across the world, there are approximately twice as many female CHWs as there are male. Hiring women has in many cases become an ethical expectation, in part because working as a CHW is often seen as empowering the CHW herself to enact positive change in her community. This article draws on interviews, participant observation, document review and a survey carried out in rural Amhara, Ethiopia from 2013 to 2016 to explore discourses and experiences of empowerment among unpaid female CHWs in Ethiopia’s Women’s Development Army (WDA). This programme was designed to encourage women to leave the house and gain decision-making power vis-à-vis their husbands—and to use this power to achieve specific, state-mandated, domestically centred goals. Some women discovered new opportunities for mobility and self-actualization through this work, and some made positive contributions to the health system. At the same time, by design, women in the WDA had limited ability to exercise political power or gain authority within the structures that employed them, and they were taken away from tending to their individual work demands without compensation. The official rhetoric of the WDA—that women’s empowerment can happen by rearranging village-level social relations, without offering poor women opportunities like paid employment, job advancement or the ability to shape government policy—allowed the Ethiopian government and its donors to pursue ‘empowerment’ without investments in pay for lower-level health workers, or fundamental freedoms introduced into state-society relations.

Not a duty but an opportunity: exploring the lived experiences of community health workers in Indiana through photovoice

Few studies have conducted photovoice projects to explore themes related to the lived experiences of community health workers (CHWs). As a relatively unknown segment of the health care workforce in the United States, CHWs are typically members of the communities they work within and fulfill unique and complementary roles through health education, health prevention, community outreach, and advocacy. This article documents a photovoice project that assessed the strengths, challenges, impacts, and what it means to be a CHW in Indiana. In this project, CHWs participated in the method of photovoice in two formal meetings – one to introduce the method and another to analyze the photographs. Participants displayed photographs, interpreted these images, and co-constructed their lived experiences. Several key themes emerged from discussion of the photographs including: participant descriptions of building individual and character traits, conceptualizations of this position, and how participants connect disparate resources for their clients. Themes and findings from this research can be utilized to reach out to potential employers and policy makers regarding the integration of CHWs into the workforce. Overall, this project documents the lived experiences of CHWs and highlights their voices as they become an accepted member within the broader workforce.

She knows that she will not come back: tracing patients and new thresholds of collective surveillance in PMTCT Option B

BACKGROUND

Malawi, Uganda, and Zimbabwe have recently adopted a universal 'test-and-treat' approach to the prevention of mother-to-child transmission of HIV (Option B+). Amongst a largely asymptomatic population of women tested for HIV and immediately started on antiretroviral treatment (ART), a relatively high number are not retained in care; they are labelled 'defaulters' or 'lost-to-follow-up' patients.

METHODS

We draw on data collected as part of a study looking at ART decentralization (Lablite) to reflect on the spaces created through the instrumentalization of community health workers (CHWs) for the purpose of bringing women who default from Option B+ back into care. Data were collected through semi-structured interviews with CHWs who are designated to trace Option B+ patients in Uganda, Malawi and Zimbabwe.

FINDINGS

Lost to follow up women give a range of reasons for not coming back to health facilities and often implicitly choose not to be traced by providing a false address at enrolment. New strategies have sought to utilize CHWs' liminal positionality - situated between the experience of living with HIV, having established local social ties, and being a caretaker - in order to track 'defaulters'. CHWs are often deployed without adequate guidance or training to protect confidentiality and respect patients' choice.

CONCLUSIONS

CHWs provide essential linkages between health services and patients; they embody the role of 'extension workers', a bridge between a novel health policy and 'non-compliant patients'. Option B+ offers a powerful narrative of the construction of a unilateral 'moral economy', which requires the full compliance of patients newly initiated on treatment.

"Contract to Volunteer": South African Community Health Worker Mobilization for Better Labor Protection

In this paper, we explore the increasing activity around labor rights for South African community health workers (CHWs). Contextualizing this activity within broader policy and legal developments, we track the emergence of sporadic mobilizations for decent work (supported by local health activist organizations) and subsequently, the formation of a CHW union. The National Union of Care Workers of South Africa (NUCWOSA) was inaugurated in 2016, hoping to secure formal and secure employment through government and the consequent labor and occupational health protections. Various tensions were observed during fieldwork in the run up to NUCWOSA's formation and raise important questions about representation, legitimacy, and hierarchies of power. We close by offering suggestions for future research in this developing space.

Community health workers, recipients' experiences and constraints to care in South Africa - a pathway to trust

Community health workers (CHWs) affiliated with community-based organisations are central to the implementation of primary health care in district health services in South Africa. Here, we explore factors that affect the provision of and access to care in two provinces - Gauteng and Eastern Cape. Drawing on narratives of care recipients and the CHWs who support them, we illustrate the complex issues surrounding health maintenance and primary care outreach in poor communities, and describe how the intimate interactions between providers and recipients work to build trust. In the study we report here, householders in Gauteng Province had poor access to health care and other services, complicating the impoverished circumstances of their everyday lives. The limited resources available to CHWs hindered their ability to meet householders' needs and for householders to benefit from existing services. CHWs in the Eastern Cape were better able to address the needs of poor householders because of the organisational support available to them. Based on an ethos of integrated and holistic care, this enabled the CHWs to address the recipients' context-related needs, and health and medical needs, while building greater levels of trust with their clients.
