Use of a community-led prevention strategy to enhance behavioral changes towards Ebola virus disease prevention: a qualitative case study in Western Côte d'Ivoire

Decolonization and antiracism: intersecting pathways to global health equity

In this paper, as Black scholars, we address ways that interventions designed to promote equity in health can create pathways for coupling decolonization with antiracism by drawing on the intersection of the health of Africans and African Americans. To frame this intersection, we offer the Public Health Critical Race Praxis (PHCRP) and the PEN-3 Cultural Model as antiracism and decolonization tools that can jointly advance research on colonization and racism globally. We argue that racism is a global reality; PHCRP, an antiracism framework, and PEN-3, a decolonizing framework, can guide interventions to promote equity for Africans and African Americans.

Leveraging community health workers for COVID-19 response in Democratic Republic of Congo, Nigeria, Senegal, and Uganda: roles, barriers, and facilitators

BACKGROUND

The Corona Virus Disease 2019 (COVID-19) pandemic overwhelmed health systems and disrupted the delivery of health services globally. Community Health Workers (CHWs) play a critical role in linking communities to health systems, supporting the prevention and control of diseases in many low- and middle-income countries. However, their roles, barriers, and facilitators in the response and control of the COVID-19 pandemic have not been well documented. We described the roles of CHWs in the COVID-19 response, including the barriers and facilitators.

METHODS

A cross-sectional study design was used to assess the COVID-19 response in the Democratic Republic of Congo (DRC), Nigeria, Senegal, and Uganda. This involved 110 key informant interviews with policymakers, health facility managers, district health managers, and CHWs to understand the role of CHWs in the COVID 19 response, selected purposively. The total sample size was based on information saturation in each of the countries. A document review on the COVID-19 response was also conducted. We searched Google, Google Scholar, and PubMed for published and grey literature. Data from the selected documents were extracted into a Google master matrix in MS Excel and analyzed thematically.

RESULTS

In COVID-19 Control, CHWs supported community-based surveillance, contact tracing, risk communication, community mobilization, and home-based care. To support the continuity of other non-COVID-19 services, the CHWs conducted community mobilization, sensitizations, outreaches, referrals, and patient follow-ups. CHWs were challenged by movement restrictions, especially in the initial stages of the lockdown, inadequate PPE, increased workload, low allowances, and motivation. CHW were facilitated by trainings, the development of guidelines, development partners' support/funding, and the provision of personal protective equipment (PPE) and tools.

CONCLUSION

CHWs supported both the COVID-19 control and continuity of non-COVID-19 health care during the COVID-19 pandemic. CHWs are a critical resource that must be adequately supported to build resilient health systems.

Community health workers and Covid-19: Cross-country evidence on their roles, experiences, challenges and adaptive strategies

Community health workers (CHWs) are a key part of the health workforce, with particular importance for reaching the most marginalised. CHWs' contributions during pandemics have received growing attention, including for COVID-19. This paper contributes to learning about CHWs' experiences during COVID-19, based on evidence from India, Bangladesh, Pakistan, Sierra Leone, Kenya and Ethiopia. The paper synthesises evidence from a set of research projects undertaken over 2020-2021. A thematic framework based on the research focus and related literature was used to code material from the reports. Following further analysis, interpretations were verified with the original research teams. CHWs made important contributions to the COVID-19 response, including in surveillance, community education, and support for people with COVID-19. There was some support for CHWs' work, including training, personal protective equipment and financial incentives. However, support varied between countries, cadres and individual CHWs, and there were significant gaps, leaving CHWs vulnerable to infection and stress. CHWs also faced a range of other challenges, including health system issues such as disrupted medical supply chains, insufficient staff and high workloads, a particular difficulty for female CHWs who were balancing domestic responsibilities. Their work was also affected by COVID-19 public health measures, such as restrictions on gatherings and travel; and by supply-side constraints related to community access and attitudes, including distrust and stigmatization of CHWs as infectious or informers. CHWs demonstrated commitment in adapting their work, for example ensuring patients had adequate drugs in advance of lockdowns, and using their own money and time to address increased transport costs and higher workloads. Effectiveness of these adaptations varied, and some involved coping in a context of inadequate support. CHW are critical for effective response to disease outbreaks, including pandemics like COVID-19. To support CHWs' contribution and protect their wellbeing, CHWs need adequate resources, managerial support, and motivation.

Community Health Workers in Pandemics: Evidence and Investment Implications

Community health workers have long played a critical role in preventing, detecting, and responding to pandemics across the globe. To expand, improve, and institutionalize these services, changes in the approach to bi/multilateral aid and private philanthropic investments in low- and middle-income countries are required.

Rethinking development interventions through the lens of decoloniality in sub-Saharan Africa: The case of global health

There has been much talk about decolonizing global health lately. The movement, which has arisen in various communities around the world, suggests an interesting critique of the Western dominant model of representations. Building upon the 'decolonial thinking' movement from the perspective of Francophone African philosophers, we comment on its potential for inspiring the field of global healthinterventions. Using existing literature and personal reflections, we reflect on two widely known illustrations of global health interventions implemented in sub-Saharan Africa - distribution of contraceptives and dissemination of Ebola virus prevention and treatment devices - featuring different temporal backdrops. We show how these solutions have most often targeted the superficial dimensions of global health problems, sidestepping the structures and mental models that shape the actions and reactions of African populations. Lastly, we question the ways through which the decolonial approach might indeed offer a credible positioning for rethinking global health interventions.

Reflecting on knowledge translation strategies from global health research projects in Tunisia and the Republic of Côte d'Ivoire

OBJECTIVES

We describe the knowledge translation strategies in two projects and share lessons learned about knowledge sharing and uptake.

METHODS

To generate findings for dissemination: (1) the Republic of Côte d'Ivoire (RCI) project relied on a multiple case study design to document barriers and facilitators to implementing a community-led prevention strategy targeting Ebola virus disease; and (2) the Tunisia project used several designs to assess a mental health training's effectiveness, and a case study design to explore contextual factors that may influence anticipated outcomes.

RESULTS

To share findings with participants, the RCI project relied on workshops and a pamphlet, and the Tunisia project relied on a structured half-day dissemination workshop and research summary. Facilitators that may have encouraged sharing and using findings include involving champions in dissemination activities, ongoing collaboration, and developing/implementing context-specific knowledge sharing strategies. Barriers include omitting to assess strategies, limited consideration of a wider audience, and the exclusion of a knowledge translation training component.

CONCLUSIONS

Our experiences might be useful to contexts involved in global and public health research that wish to address the "know-do gap."

Community-Based Surveillance in Côte d'Ivoire

Community-based surveillance can be an important component of early warning systems. In 2016, the Côte d'Ivoire Ministry of Health launched a community-based surveillance project in 3 districts along the Guinea border. Community health workers were trained in detection and immediate reporting of diseases and events using a text-messaging platform. In December 2017, surveillance data from before and after implementation of community-based surveillance were analyzed in intervention and control districts. A total of 3,734 signals of priority diseases and 4,918 unusual health events were reported, of which 420 were investigated as suspect diseases and none were investigated as unusual health events. Of the 420 suspected cases reported, 23 (6%) were laboratory confirmed for a specific pathogen. Following implementation of community-based surveillance, 5-fold and 8-fold increases in reporting of suspected measles and yellow fever clusters, respectively, were documented. Reporting incidence rates in intervention districts for suspected measles, yellow fever, and acute flaccid paralysis were significantly higher after implementation, with a difference of 29.2, 19.0, and 2.5 cases per 100,000 person-years, respectively. All rate differences were significantly higher in intervention districts (p < 0.05); no significant increase in reporting was noted in control districts. These findings suggest that community-based surveillance strengthened detection and reporting capacity for several suspect priority diseases and events. However, the surveillance program was very sensitive, resulting in numerous false-positives. Learning from the community-based surveillance implementation experience, the ministry of health is revising signal definitions to reduce sensitivity and increase specificity, reviewing training materials, considering scaling up sustainable reporting platforms, and standardizing community health worker roles.

Integrating the prevention of mother-to-child transmission of HIV into primary healthcare services after AIDS denialism in South Africa: perspectives of experts and health care workers - a qualitative study

Background

Integrating Prevention of Mother-to-Child Transmission (PMTCT) programmes into routine health services under complex socio-political and health system conditions is a priority and a challenge. The successful rollout of PMTCT in sub-Saharan Africa has decreased Human Immunodeficiency Virus (HIV), reduced child mortality and improved maternal health. In South Africa, PMTCT is now integrated into existing primary health care (PHC) services and this experience could serve as a relevant example for integrating other programmes into comprehensive primary care. This study explored the perspectives of both experts or key informants and frontline health workers (FHCWs) in South Africa on PMTCT integration into PHC in the context of post-AIDS denialism using a Complex Adaptive Systems framework.

Methods

A total of 20 in-depth semi-structured interviews were conducted; 10 with experts including national and international health systems and HIV/PMTCT policy makers and researchers, and 10 FHCWs including clinic managers, nurses and midwives. All interviews were conducted in person, audio-recorded and transcribed. Three investigators collaborated in coding transcripts and used an iterative approach for thematic analysis.

Results

Experts and FHCWs agreed on the importance of integrated PMTCT services. Experts reported a slow and partial integration of PMTCT programmes into PHC following its initial rollout as a stand-alone programme in the aftermath of the AIDS denialism period. Experts and FHCWs diverged on the challenges associated with integration of PMTCT. Experts highlighted bureaucracy, HIV stigma and discrimination and a shortage of training for staff as major barriers to PMTCT integration. In comparison, FHCWs emphasized high workloads, staff turnover and infrastructural issues (e.g., lack of rooms, small spaces) as their main challenges to integration. Both experts and FHCWs suggested that working with community health workers, particularly in the post-partum period, helped to address cases of loss to follow-up of women and their babies and to improve linkages to polymerase-chain reaction (PCR) testing and immunisation.

Conclusions

Despite organised efforts in South Africa, experts and FHCWs reported multiple barriers for the full integration of PMTCT in PHC, especially postpartum. The results suggest opportunities to address operational challenges towards more integrated PMTCT and other health services in order to improve maternal and child health.

Community Health Workers and Pandemic Preparedness: Current and Prospective Roles

Despite the importance of community health workers (CHWs) to health systems in resource-constrained environments, relatively little has been written about their contributions to pandemic preparedness. In this perspective piece, we draw from the response to the 2014 Ebola and 2015 Zika epidemics to review examples whereby CHWs contributed to health security and pandemic preparedness. CHWs promoted pandemic preparedness prior to the epidemics by increasing the access to health services and products within communities, communicating health concepts in a culturally appropriate fashion, and reducing the burdens felt by formal healthcare systems. During the epidemics, CHWs promoted pandemic preparedness by acting as community-level educators and mobilizers, contributing to surveillance systems, and filling health service gaps. Acknowledging the success CHWs have had in these roles and in previous interventions, we propose that the cadre may be better engaged in pandemic preparedness in the future. Some practical strategies for achieving this include training and using CHWs to communicate One Health information to at-risk communities prior to outbreaks, pooling them into a reserve health corps to be used during public health emergencies, and formalizing agreements and strategies to promote the early engagement of CHWs in response actions. Recognizing that CHWs already play a role in pandemic preparedness, we feel that expanding the roles and responsibilities of CHWs represents a practical means of improving pandemic and community-level resilience.
