Mortality among 5 to 19-year-olds in rural Mali
The unique healthcare needs of 5 to 9-year-olds and adolescents (10 – 19 years) in low- and middle-income countries have been largely neglected. We generated estimates of 5 to 9-year-old and adolescent mortality in rural Mali, a setting with high under-five mortality, and aimed to define associated individual and household risk factors. We analysed cross-sectional baseline household survey data from the ProCCM trial (NCT02694055) conducted in Ban…
Cost-effectiveness analysis of proactive home visits compared with site-based community health worker care on antenatal care outcomes in Mali
INTRODUCTION: Despite recommendations from the WHO, antenatal care (ANC) coverage remains low in many low-income and middle-income countries (LMICs). Community health workers (CHWs) can play an important role in expanding ANC coverage through pregnancy identification, provision of health education, screening for complications, delivery of therapeutic care and referral to higher levels of care. However, despite the success of CHW programmes in var…
Qualified, skilled or trained delivery care provider
box This commentary highlights various definitions of maternal and newborn health care providers used globally and demonstrates the considerable effect of a definition on study findings
Community case management to accelerate access to healthcare in Mali
The Proactive Community Case Management (ProCCM) trial in Mali reinforced the health system across both arms with user fee removal, professional community health workers (CHWs) and upgraded primary health centres (PHCs)—and randomized village-clusters to receive proactive home visits by CHWs (intervention) or fixed site-based services by passive CHWs (control). Across both arms, sick children’s 24-hour treatment and pregnant women’s four or more …
Effect of community health worker home visits on antenatal care and institutional delivery
INTRODUCTION: Though community health workers (CHWs) have improved access to antenatal care (ANC) and institutional delivery in different settings, it is unclear what package and delivery strategy maximises impact. METHODS: This study reports a secondary aim of the Proactive Community Case Management cluster randomised trial, conducted between December 2016 and April 2020 in Mali. It evaluated whether proactive home visits can improve ANC access …
Effects of proactive vs fixed community health care delivery on child health and access to care
Background: Professional community health workers (CHWs) can help achieve universal health coverage, although evidence gaps remain on how to optimise CHW service delivery. We conducted an unblinded, parallel, cluster randomised trial in rural Mali to determine whether proactive CHW delivery reduced mortality and improved access to health care among children under five years, compared to passive delivery. Here we report the secondary access endpoi…
Effect of mobile application user interface improvements on minimum expected home visit coverage by community health workers in Mali
BACKGROUND: Proactive community case management (ProCCM) has shown promise to advance goals of universal health coverage (UHC). ProCCM community health workers (CHWs) face operational challenges when pursuing their goal of visiting every household in their service area at least twice monthly to proactively find sick patients. We developed a software extension (UHC Mode) to an existing CHW mobile application featuring user interface design improve…
Compensation models for community health workers
BACKGROUND: , there is an urgent need to better understand the types of CHW payment models and their implications. METHODS: This study examines the legal framework on CHW compensation in five countries: Brazil, Ghana, Nigeria, Rwanda, and South Africa. In order to map the characteristics of each approach, a review of the regulatory framework governing CHW compensation in each country was undertaken. Law firms in each of the five countries were en…
Household factors and under-five mortality in Bankass, Mali
U5 mortality is very high in Bankass and is associated with living a greater distance from healthcare and several other household factors that may be amenable to intervention or facilitate program targeting
Prioritising the role of community health workers in the Covid-19 response
COVID-19 disproportionately affects the poor and vulnerable. Community health workers are poised to play a pivotal role in fighting the pandemic, especially in countries with less resilient health systems. Drawing from practitioner expertise across four WHO regions, this article outlines the targeted actions needed at different stages of the pandemic to achieve the following goals: (1) PROTECT healthcare workers, (2) INTERRUPT the virus, (3) MAIN…
Improving Community Health Worker performance by using a personalised feedback dashboard for supervision
BACKGROUND: Countries across sub-Saharan Africa are scaling up Community Health Worker (CHW) programmes, yet there remains little high-quality research assessing strategies for CHW supervision and performance improvement. This randomised controlled trial aimed to determine the effect of a personalised performance dashboard used as a supervision tool on the quantity, speed, and quality of CHW care. METHODS: We conducted a randomised controlled tri…

INTRODUCTION: Despite decades of experience with community health workers (CHWs) in a wide variety of global health projects, there is no established conceptual framework that structures how implementers and researchers can understand, study and improve their respective programs based on lessons learned by other CHW programs. OBJECTIVE: To apply an original, non-linear framework and case study method, 5-SPICE, to multiple sister projects of a lar…
