Community health workers during the Ebola outbreak in Guinea, Liberia, and Sierra Leone

The effectiveness of rural community health workers in improving health outcomes during the COVID-19 pandemic: a systematic review

BACKGROUND

Rural community health workers [CHWs] play a critical role in improving health outcomes during non-pandemic times, but evidence on their effectiveness during the COVID-19 pandemic is limited. There is a need to focus on rural CHWs and rural health systems as they have limited material and human resources rendering them more vulnerable than urban health systems to severe disruptions during pandemics.

OBJECTIVES

This systematic review aims to describe and appraise the current evidence on the effectiveness of rural CHWs in improving access to health services and health outcomes during the COVID-19 pandemic in low-and middle-income countries [LMICs].

METHODS

We searched electronic databases for articles published from 2020 to 2023 describing rural CHW interventions during the COVID-19 pandemic in LMICs. We extracted data on study characteristics, interventions, outcome measures, and main results. We conducted a narrative synthesis of key results.

RESULTS

Fifteen studies from 10 countries met our inclusion criteria. Most of the studies were from Asia [10 of 15 studies]. Study designs varied and included descriptive and analytical studies. The evidence suggested that rural CHW interventions led to increased household access to health services and may be effective in improving COVID-19 and non-COVID-19 health outcomes. Overall, however, the quality of evidence was poor due to methodological limitations; 14 of 15 studies had a high risk of bias.

CONCLUSION

Rural CHWs may have improved access to health services and health outcomes during the COVID-19 pandemic in LMICs but more rigorous studies are needed during future pandemics to evaluate their effectiveness in improving health outcomes in different settings and to assess appropriate support required to ensure their impact at scale.

The role of community engagement toward ensuring healthy lives: a case study of COVID-19 management in two Ghanaian municipalities

Introduction

Community engagement is one of the important requirements for strengthening health delivery in communities in a bid to achieve sustainable development goal 3, target 3.3 (SDG 3.3). The World Health Organization has strongly encouraged the use the five levels of community engagement, which are informing, consulting, planning, collaborating, and empowering communities in order to build resilience and to enable them contribute to the fight against diseases and for the uptake of health interventions. This study sought to explore and describe from the view of government institutions in Ghana how they engaged communities in COVID- 19 management and vaccine acceptance and how the communities within two municipalities also perceived the engagement process as well as the lessons that can be learned in engaging communities to deal with other health challenges and interventions toward the attainment of SDG 3 target 3.3.

Materials and methods

This case study qualitative research project employed in-depth interviews among 36 respondents composed of government officials (the Ghana Health Service (GHS), the Information Services Department (ISD), the National Commission on Civic Education (NCCE) and two Municipal Assemblies), and community leaders and 10 focus group discussions among 87 men and women most of whom were natives and some migrants in two administrative municipalities in Ghana. Data were collected from June to September 2021. Audio interviews were transcribed and uploaded to Nvivo 12 to support triangulation, coding, and thematic analysis. Ethical approval was obtained from the University of Health and Allied Sciences' Research Ethics Committee and all COVID-19 restrictions were observed.

Results

The findings revealed that all the four government institutions educated and informed the communities within their municipalities on COVID-19 management and vaccine acceptance. However, the Ghana Health Service was the most effective in the engagement spectrum of the other four; consulting, involving, collaborating, and empowering communities in the process of COVID-19 management and vaccine acceptance. The GHS achieved that through its CHPS program, which ensured a decentralized health service provision system with multiple programs and leveraging on its multiple programs to reach out to the communities. Government institutions such as the NCCE and the ISD faced challenges such as limited funding and support from the government to be able to carry out their tasks. Additionally, they were not involved with the communities prior to the pandemic and for that matter, they did not have access to community systems such as committees, and existing groups to facilitate the engagement process.

Discussion

Using communities to support Ghana's attainment of the SDG 3 target 3.3 is possible; however, the government needs to provide funds and resources to the institutions responsible to enable them to carry out community engagement effectively. Also, promoting decentralization among institutions can strengthen community engagement processes. It is important that state institutions continue to strategize to empower communities in order to promote their participation in healthcare interventions and in the fight against infectious diseases in Ghana.

From policy to practice: a qualitive study exploring the role of community health workers during the COVID-19 response in Sierra Leone

BACKGROUND

During the COVID-19 pandemic, community health workers (CHWs) were required to help their communities respond to the outbreak in Sierra Leone. The Government of Sierra Leone released a policy that provided an interim guidance on the specific role of CHWs during the pandemic including support required to maintain continuity of routine and essential services during the COVID-19 response. This study explores how CHWs adapted their roles during the COVID-19 pandemic in Sierra Leone and the support they received from families, communities, and the health system.

METHODS

A qualitative exploratory study was conducted in two districts in Sierra Leone. We conducted eight key informant interviews with district and community level managers and leaders and four focus group discussions with CHWs. Thematic data analysis and synthesis were guided by the interim guidance released by the Government of Sierra Leone at the onset of the COVID-19 pandemic and supported by NVivo 11.

RESULTS

CHWs quickly took on COVID-19 frontline roles which included surveillance, contact tracing, social mobilization, and provision of psychosocial support. CHWs were trusted with these responsibilities as they were recognized as being knowledgeable about the community, were able to communicate effectively with community members and had experience of dealing with other outbreaks. Despite the release of the interim guidance aimed to optimize CHW contribution, motivate CHWs, ensure continuity of core and essential community-based services alongside COVID-19 services, CHWs faced many challenges in their work during the pandemic including heavy workload, low financial remuneration, lack of mental health support, and shortages of protective equipment, communication and transportation allowances. However, they were generally satisfied with the quality of the training and supervision they received. Support from families and communities was mixed, with some CHWs experiencing stigma and discrimination.

CONCLUSION

During the COVID-19 pandemic, CHWs played a critical role in Sierra Leone. Although, a policy was released by the government to guide their role during the crisis, it was not fully implemented. This resulted in CHWs being overworked and under supported. It is important that CHWs are provided with the necessary training, tools and support to take on their vital roles in managing health crises at the community level. Strengthening the capacity of CHWs will not only enhance pandemic response, but also lay the foundation for improved primary health care delivery and community resilience in the face of future health emergencies.

The importance of community health workers as frontline responders during the COVID-19 pandemic, Somalia, 2020-2021

Introduction

We examined the contribution of community health workers as frontline responders for the community-based surveillance in Somalia during the first year of the COVID-19 pandemic for detection of COVID-19 cases and identification of contacts.

Methods

We retrieved COVID-19 surveillance data from 16 March 2020 to 31 March 2021 from the health ministry's central database. These data were collected through community health workers, health facilities or at the points of entry. We compared the number of suspected COVID-19 cases detected by the three surveillance systems and the proportion that tested positive using the chi-squared test. We used logistic regression analysis to assess association between COVID-19 infection and selected variables.

Results

During the study period, 154,004 suspected cases of COVID-19 were detected and tested, of which 10,182 (6.6%) were positive. Of the notified cases, 32.7% were identified through the community-based surveillance system, 54.0% through the facility-based surveillance system, and 13.2% at points of entry. The positivity rate of cases detected by the community health workers was higher than that among those detected at health facilities (8.6% versus 6.4%; p < 0.001). The community health workers also identified more contacts than those identified through the facility-based surveillance (13,279 versus 1,937; p < 0.001). The odds of COVID-19 detection generally increased by age. Community-based surveillance and health facility-based surveillance had similar odds of detecting COVID-19 cases compared with the points-of-entry surveillance (aOR: 7.0 (95% CI: 6.4, 7.8) and aOR: 7.5 (95% CI: 6.8, 8.3), respectively).

Conclusion

The community health workers proved their value as first responders to COVID-19. They can be effective in countries with weak health systems for targeted community surveillance in rural and remote areas which are not covered by the facility-based surveillance system.
