The everyday political economy of health: community health workers and the response to the 2015 Zika outbreak in Brazil

Enhancing the capacity of community health workers in prevention and control of epidemics and pandemics in Wakiso district, Uganda: evaluation of a pilot project

BACKGROUND

Community Health Workers (CHWs) play a crucial role in outbreak response, including health education, contact tracing, and referral of cases if adequately trained. A pilot project recently trained 766 CHWs in Wakiso district Uganda on epidemic and pandemic preparedness and response including COVID-19. This evaluation was carried out to generate evidence on the outcomes of the project that can inform preparations for future outbreaks in the country.

METHODS

This was a qualitative evaluation carried out one year after the project. It used three data collection methods: 30 in-depth interviews among trained CHWs; 15 focus group discussions among community members served by CHWs; and 11 key informant interviews among community health stakeholders. The data was analysed using a thematic approach in NVivo (version 12).

RESULTS

Findings from the study are presented under four themes. (1) Improved knowledge and skills on managing epidemics and pandemics. CHWs distinguished between the two terminologies and correctly identified the signs and symptoms of associated diseases. CHWs reported improved communication, treatment of illnesses, and report writing skills which were of great importance including for managing COVID-19 patients. (2) Enhanced attitudes towards managing epidemics and pandemics as CHWs showed dedication to their work and more confidence when performing tasks specifically health education on prevention measures for COVID-19. (3) Improved health practices such as hand washing, vaccination uptake, and wearing of masks in the community and amongst CHWs. (4) Enhanced performance in managing epidemics and pandemics which resulted in increased work efficiency of CHWs. CHWs were able to carry out community mobilization through door-to-door household visits and talks on community radios as part of the COVID-19 response. CHWs were also able to prioritize health services for the elderly, and support the management of patients with chronic diseases such as HIV, TB and diabetes by delivering their drugs.

CONCLUSIONS

These findings demonstrate that CHWs can support epidemic and pandemic response when their capacity is enhanced. There is need to invest in routine training of CHWs to contribute to outbreak preparedness and response.

Evidence of community health workers' delivery of physical rehabilitation services in sub-Saharan Africa: a scoping review

OBJECTIVES

To map the evidence and scope of physical rehabilitation services delivered by community health workers (CHWs) in sub-Saharan Africa (SSA).

DESIGN

Scoping review DATA SOURCES: PubMed, Scopus, Cochrane Central and databases within the EBSCOhost platform. We also searched other literature sources including reference lists, conference presentations and organisational websites such as WHO, Ministries of Health and non-governmental organisations in SSA.

ELIGIBILITY CRITERIA FOR SELECTION OF STUDIES

Articles presenting evidence on CHWs' delivery of physical rehabilitation services in SSA from September 1978 to June 2023.

DATA EXTRACTION AND SYNTHESIS

Screening was conducted by two reviewers and was guided by the inclusion criteria. Thematic content analysis of data was employed. The results are presented according to the Preferred Reporting Items for Systematic Review and Meta-Analysis extension for scoping reviews.

RESULTS

A total of 6996 articles were identified through various databases, with only 20 studies qualifying for data extraction. Evidence was presented by Eritrea, Ethiopia, Malawi, Mauritius, Namibia, South Africa and Uganda. Assessments, case management, health education, community liaison with support, health systems linkage and administration were the CHWs' scope of practice identified. The review identified home-based, community-based, community and facility-based, home and community-based and facility-based as modes of delivery. The barriers experienced are resources, societal and community attitudes, governance, geographical barriers and delivery capacity, while proximity to the community, positive job attitude and support with collaboration facilitated service delivery.

CONCLUSION

Training and integrating CHWs in national health care systems, with careful selection of existing CHWs, would minimise the barriers faced.

The intersectionality of health (in)security: Healthcare, disposable workers, and exposure within Brazil's pandemic politics

Brazil has suffered severe consequences from the Covid-19 pandemic, currently ranking second globally in terms of total fatalities, with more than 682,000 lives lost. This article critically outlines how a 'health security' framework overlooks processes of intersectionality and the varying impacts of the virus on different segments of society, or what we term health insecurity. We organize our analysis around three aspects of the pandemic that have become salient in Brazilian society, namely access to healthcare, disposable workers, and exposure to the virus, and delineate the intersectional impact of gendered inequality, neoliberal ideologies, and racial hierarchies within these three themes. Our methodology employs media and scholarly interpretations of Covid-19, and other secondary empirical and statistical data, to outline the virus's impacts on differently positioned bodies throughout Brazilian society. Our main findings reveal that during the pandemic, women's labor and health concerns have been undervalued, exploitative working conditions have been exacerbated, and Afro-Brazilians have been put in situations of higher exposure to the virus in both public and private spaces. This article underscores the need to better examine how public health, systems of oppression and exclusion, and (in)security overlap with each other.

Democratizing Public Health: Participatory Policymaking Institutions, Mosquito Control, and Zika in the Americas

The Zika virus is a mosquito-borne virus spread primarily by Aedes mosquitoes. Zika cases have been detected throughout the mosquito's range, with an epidemic occurring from 2015 to 2017 in Brazil. Many Zika cases are mild or asymptomatic, but infections in pregnant women can cause microcephaly in children, and a small percentage of cases result in Guillan-Barré syndrome. There is currently little systematic information surrounding the municipal spread of the Zika Virus in Brazil. This article uses coarsened exact matching with negative binomial estimation and ordinary least squares estimation to assess the determinants of Zika incidence across the ~280,000 cases confirmed and recorded by Brazil's Ministry of Health in 2016 and 2017. These data come from Freedom of Information Act (FOIA) requests in Brazil and have not been published. We use data on the universe of individual Zika cases in Brazil and Geographic Information Systems (GIS) software to examine the virus at the municipal level across 5570 municipalities and construct a unique, unusually rich dataset covering daily Zika transmission. Additionally, our dataset includes corresponding local data on democratic governance, mosquito control efforts, and environmental conditions to estimate their relationship to Zika transmission. The results demonstrate that the presence of subnational democratic, participatory policymaking institutions and high levels of local state capacity are associated with low rates of Zika contraction. These models control for local healthcare spending and economic conditions, among other factors, that also influence Zika contraction rates. In turn, these findings provide a better understanding of what works for local health governance and mosquito control and makes important data public so that scholars and practitioners can perform their own analyses. Stronger models of Zika transmission will then inform mosquito abatement efforts across the Global South, as well as provide a blueprint for combatting Dengue fever, which is also transmitted by Aedes mosquitoes.

The impact of the COVID-19 pandemic in the frontline health workforce: Perceptions of vulnerability of Brazil's community health workers

The COVID-19 pandemic has resulted in calls for an increased integration of community health workers (CHWs) into the health system response. Historically, CHWs can play an important role in ensuring the sustainability of health policy implementation - by addressing social determinants of health and maintaining care for ongoing health problems. Their frontline work, with close contact to populations, places CHWs in a position of increased vulnerability to becoming infected and to being the target of abuse and violence. These vulnerabilities compound underlying problems faced by CHWs, who often come from poor backgrounds, are insufficiently paid and receive inadequate training. Speaking to a scarcity of studies on how CHWs are impacted by the pandemic, this paper conducts a systematic study of CHWs in Brazil. Based on quantitative and qualitative data collected during June and July 2020, it considers perceptions and experiences of CHWs, comparing them with other health professionals. We study the extent to which the pandemic added to existing vulnerabilities and created new problems and imbalances in the work of CHWs. We conclude that COVID-19 led to a deterioration of the working conditions of CHWs, of their relations with other health professionals, and of their ability to carry out their essential work in the public health system.

Inequality in the middle of a crisis: an analysis of health workers during the COVID-19 pandemic from the profession, race, and gender perspectives

Abstract Studies show that people in vulnerable conditions and some social groups such as women and black people have suffered more intensely from the COVID-19 pandemic impacts. This expression of inequality also manifests itself among healthcare workers, with greater exposure of some specific groups. This paper analyzes the effect of COVID-19 on health care workers and the working conditions in the Brazilian public health system, analyzed from professional, gender, and race perspectives. Data were collected from an online survey of 1,829 health workers conducted in March 2021. Indeed, we identified inequalities in health workers’ experiences during the health crisis generated by COVID-19, which are marked by the profession of each worker and are traversed by their gender and race traits.

Desigualdade em meio à crise: uma análise dos profissionais de saúde que atuam na pandemia de COVID-19 a partir das perspectivas de profissão, raça e gênero

Resumo Estudos mostram que pessoas em condições de vulnerabilidade têm sofrido de forma mais intensa os impactos da pandemia de COVID-19, assim como alguns grupos sociais, como mulheres e negros. Essa expressão de desigualdade também se manifesta entre os trabalhadores da saúde, com maior exposição de alguns grupos específicos. Este artigo analisa a incidência da COVID-19 sobre os trabalhadores da saúde a partir das perspectivas de profissão, gênero e raça. Os dados foram coletados por uma survey online com 1.829 trabalhadores da saúde, realizada no mês de março de 2021. Encontramos que, efetivamente, há desigualdades nas experiências dos trabalhadores da saúde durante a crise sanitária gerada pela COVID-19. Essas desigualdades estão marcadas pela profissão de cada trabalhador e são atravessadas por suas características de gênero e raça.

Are community health programmes always benign? Community health worker perceptions and the social construction of users in Brazil’s primary healthcare policy

We examine how community health workers (CHWs), while working as links between doctors, nurses and vulnerable groups, participate in the social construction of citizens in the implementation of Brazil's primary healthcare policy. Drawing on interviews and a vignette experiment with CHWs in the city of São Paulo, we show that perceptions of CHWs about the vulnerability and agency of health system users impact upon their referrals to other levels of service. Judgments about the socioeconomic, cultural and moral conditions of families determine different referrals - on the one hand, to practices based on persuasion and respect for individual choices; on the other, to 'top-down' or forcible interventions. While implementing the same healthcare policy, CHWs construct users as (responsible) agents or (helpless) targets, thus determining different pathways in the health system and shaping the relationship between citizens and the state. Brazil's primary health policy, while seeking to tackle vulnerability, is also a site where social representations are reproduced that contribute to the denial of the agency of citizens deemed more vulnerable and to the definition of their bodies as sites for state intervention.

MEWAR: Development of a Cross-Platform Mobile Application and Web Dashboard System for Real-Time Mosquito Surveillance in Northeast Brazil

Mosquito surveillance is a crucial process for understanding the population dynamics of mosquitoes, as well as implementing interventional programs for controlling and preventing the spread of mosquito-borne diseases. Environmental surveillance agents who performing routine entomological surveys at properties in areas where mosquito-borne diseases are endemic play a critical role in vector surveillance by searching and destroying mosquito hotspots as well as collate information on locations with increased infestation. Currently, the process of recording information on paper-based forms is time-consuming and painstaking due to manual effort. The introduction of mobile surveillance applications will therefore improve the process of data collection, timely reporting, and field worker performance. Digital-based surveillance is critical in reporting real-time data; indeed, the real-time capture of data with phones could be used for predictive analytical models to predict mosquito population dynamics, enabling early warning detection of hotspots and thus alerting fieldworker agents into immediate action. This paper describes the development of a cross-platform digital system for improving mosquito surveillance in Brazil. It comprises of two components: a dashboard for managers and a mobile application for health agents. The former enables managers to assign properties to health workers who then survey them for mosquitoes and to monitor the progress of inspection visits in real-time. The latter, which is primarily designed as a data collection tool, enables the environmental surveillance agents to act on their assigned tasks of recording the details of the properties at inspections by filling out digital forms built into the mobile application, as well as details relating to mosquito infestation. The system presented in this paper was co-developed with significant input with environmental agents in two Brazilian cities where it is currently being piloted.

Gender and Race on the Frontline: Experiences of Health Workers in Brazil during the COVID-19 Pandemic

Studies on the differential effects of health emergencies have largely overlooked women health workers. Whilst the literature has shown the impact of Coronavirus disease-19 (COVID-19) on women and on healthcare workers, little research has considered the gendered effects of the health workforce. This article analyses the impact of COVID-19 on healthcare workers and working conditions in Brazil's public healthcare system, through consideration of gendered and racialized understandings of care and work. Data were taken from an online survey of 1,263 health workers, undertaken between September and October 2020, disaggregated by sex and by race in order to understand health workers' experiences of the pandemic in one of the countries most significantly affected by the crisis.

Working through the fog of a pandemic: Street-level policy entrepreneurship in times of crises

Imposing significant challenges for both street-level implementation and policy (re)design, crises alter the environment for street-level policy entrepreneurship (SLPE), wherein street-level bureaucrats engage in policy formulation processes to secure future policy outcomes. Nevertheless, like street-level implementation in general, SLPE is studied during ordinary times but rarely during crises. Focusing on community-health workers in Brazil during the Covid-19 crisis uncovered a defensive motivation for SLPE, which aimed to legitimize community healthcare as an integral part of pandemic treatment, reforming the government's hitherto neglectful approach to community health services. Moreover, the continuing crisis created an unusually prolonged window of opportunity for securing community healthcare provision. By utilizing collective efforts and drawing on powerful politicians' mobilization, SLPE during crisis shares similarities with, yet differs from, SLPE during ordinary times, while further closing the interstices between local, professional, and political perspectives in the formulation of policy decisions.

Public health messages on arboviruses transmitted by Aedes aegypti in Brazil

BACKGROUND

The outbreak of Zika virus in Brazil in 2015 followed the arrival of chikungunya in 2014 and a long history of dengue circulation. Vital to the response to these outbreaks of mosquito-borne pathogens has been the dissemination of public health messages, including those promoted through risk communication posters. This study explores the content of a sample of posters circulated in Brazil towards the end of the Zika epidemic in 2017 and analyses their potential effectiveness in inducing behaviour change.

METHODS

A content analysis was performed on 37 posters produced in Brazil to address outbreaks of mosquito-borne pathogens. The six variables of the Health Belief Model were used to assess the potential effectiveness of the posters to induce behaviour change.

RESULTS

Three overarching key messages emerged from the posters. These included (i) the arboviruses and their outcomes, (ii) a battle against the mosquito, and (iii) a responsibility to protect and prevent. Among the six variables utilised through the Health Belief Model, cues to action were most commonly featured, whilst the perceived benefits of engaging in behaviours to prevent arbovirus transmission were the least commonly featured.

CONCLUSIONS

The posters largely focused on mosquito-borne transmission and the need to eliminate breeding sites, and neglected the risk of the sexual and congenital transmission of Zika and the importance of alternative preventive actions. This, we argue, may have limited the potential effectiveness of these posters to induce behaviour change.

How do community health workers institutionalise: An analysis of Brazil's CHW programme

Community health workers (CHWs) are framed as the link between communities and the formal health system. CHWs must establish trusting relationships with the community and with the broader health service. How to find the optimal balance between the various strands of work for CHWs, and how to formalise this, has been the focus of different studies. We performed an extensive documentary analysis of federal legislation in Brazil to understand the institutionalisation of the CHW workforce in Brazil over the last 3 decades. The paper offers three contributions to the literature: the development and application of an analytical framework to consider the institutionalisation process of CHWs; a historical analysis of the professional institutionalisation of CHW in Brazil; and the identification of the paradoxes that such institutionalisation faces: firstly, institutionalisation focused on improving CHW remuneration created difficulties in hiring and paying these professionals; when CHW are incorporated within state bureaucracy they start to lose their autonomy as community agents; and that the effectiveness of CHW programmes depends on the improvement of clinical services in the most deprived areas.

The vulnerabilities of the Brazilian health workforce during health emergencies: Analysing personal feelings, access to resources and work dynamics during the COVID-19 pandemic

Public health emergencies are a test of resilience for health systems, which depend on health workforces that are well managed and cared for. The COVID‐19 pandemic exposed the weakness of many health systems in preparing their health workforces. The crisis also exacerbated the unequal conditions between different professions, an issue that is still understudied in the workforce literature. This paper analyzes the consequences of the COVID‐19 pandemic for different health professionals, considering the ways in which Brazil's the health system does or does not protect them. We also analyse the role of pre‐existing inequalities between different professions and social groups within the workforce in shaping their different experiences of the pandemic. We present data comparing the perceptions of different health professionals facing the pandemic in Brazil: physicians, nurses, and community health workers. Data were collected in an online survey in Brazil with 1630 health care workers between June 15th and July 1st. Findings suggest that none of the professions felt well prepared to work under emergencies. However, differences relating to professional background were exacerbated during the pandemic, creating unequal conditions for different health workers. These inequalities may pose new challenges for the post‐pandemic scenario.

Desafios para a Atenção Primária à Saúde no Brasil: uma análise do trabalho das agentes comunitárias de saúde durante a pandemia de Covid-19

Resumo As fragilidades da Atenção Primária à Saúde podem ser reconhecidas por meio da análise do trabalho das agentes comunitárias de saúde. Uma vez que a situação enfrentada por essas profissionais representa desafios estruturais do sistema de saúde, este artigo tem como objetivo analisar a situação das profissionais em questão no enfrentamento à pandemia de Covid-19 no Brasil. Analisamos seus desafios com base nos dados coletados em um inquérito online e em netnografia. Para a realização da análise dos dados, optamos pela análise de conteúdo, inspirada na grounded-theory. Observamos três dimensões que representam como as agentes comunitárias de saúde experienciam a pandemia: mudanças nas práticas de trabalho, bem como nas interações entre trabalhadores e usuários e a expectativa do futuro no trabalho pós-pandemia. As análises mostram que para resguardar essas profissionais e garantir o funcionamento da Atenção Primária à Saúde é necessário contar com novas estratégias para viabilizar as dinâmicas locais de trabalho.

Neoliberal economics, planetary health, and the COVID-19 pandemic: a Marxist ecofeminist analysis

Planetary health sees neoliberal capitalism as a key mediator of socioecological crises, a position that is echoed in much COVID-19 commentary. In this Personal View, I set out an economic theory that emphasises some of the ways in which neoliberal capitalism's conceptualisation of value has mediated responses to COVID-19. Using the intersection of ecological, feminist, and Marxist economics, I develop an analysis of neoliberal capitalism as a specific historical form of the economy. I identify the accumulation of exchange value as a central tendency of neoliberal capitalism and argue that this tendency creates barriers to the production of other forms of value. I then analyse the implications of this tendency in the context of responses to COVID-19. I argue that resources and labour flow to the production of exchange value, at the expense of production of other value forms. Consequently, the global capitalist economy has unprecedented productive capacity but uses little of this capacity to create the conditions that improve and maintain people's health. To be more resilient to coming crises, academics, policy makers, and activists should do theoretical work that enables global economies to recognise multiple forms of value and political work that embeds these theories in societal institutions.

A rights-based approach to public health emergencies: The case of the 'More Rights, Less Zika' campaign in Brazil

During health emergencies, the security agenda tends to impose itself over the human rights agenda. That happened when Brazil became the Zika-related PHEIC epicentre in 2016. While the federal government promoted a 'war against the mosquito' Aedes aegypti, some social actors emphasised the social determinants of health and women's rights. This article presents the United Nations Population Fund (UNFPA) led campaign 'More Rights, Less Zika' as a consistent example of the positive effects the coordination between global and local actors might have on health initiatives. We conducted field research in Recife, Northeast of Brazil, one of the campaign's target cities, where we interviewed main local actors. The campaign focussed on disseminating women's sexual and reproductive rights as an alternative to the strategy of the federal government, primarily focussed on controlling the vector, postponing pregnancies, and the use of repellent. Despite its scale limitations, the campaign demonstrates that a right-based approach can contribute to increasing the security of communities during health emergencies. The case also suggests that coordinating global actors' actions with local actors improves the quality of global health initiatives, which is particularly important when a conservative agenda opposing women's rights gains leverage in Brazil and other States.
