Acceptability of the R21/Matrix-M malaria vaccine alongside existing malaria interventions in the trial context
BACKGROUND: The R21/Matrix-M malaria vaccine has been shown to provide high protective efficacy against malaria in a phase III trial, and has been recommended for use by WHO. The vaccine will soon be deployed at scale in sub-Saharan Africa. This study aimed to understand the caregiver and community acceptability of the R21/Matrix-M vaccine alongside existing malaria prevention interventions, according to the communities of participants in the sea…
How, why, and under what circumstances can supportive supervision programs improve malaria case management? A realist program theory
Supportive supervision (SS) programs aim to enhance the quality of care by strengthening the performance of health providers. Commonly part of broader quality improvement efforts, SS programs are increasingly used in low-and middle-income countries to improve malaria case management. Despite substantial investments and some positive outcomes, little is known about what drives their effectiveness. A realist evaluation was conducted in Tanzania and…
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 …
Delivery strategies for malaria vaccination in areas with seasonal malaria transmission
Background Seasonal vaccination with the RTS,S/AS01 E malaria vaccine given alongside seasonal malaria chemoprevention (SMC) substantially reduces malaria in young children. The WHO has recommended the use of RTS,S/AS01 E , including seasonal vaccination, in areas with seasonal malaria transmission. This study aimed to identify potential strategies to deliver RTS,S/AS01 E , and assess the considerations and recommendations for delivery of seasona…
An absence of evidence breeds contempt
Poor-quality medicines pose a significant challenge for health systems in low- to middle-income countries (LMICs),with recent deaths in multiple countries following ingestion of substandard cough syrups emphasising the need for quality-assurance of medicines in our increasingly interconnected global markets. Research also suggests that the source (country of manufacture) and type of medicine (generic/brand) are perceived to be associated with med…
RTS,S/AS01 malaria vaccine pilot implementation in western Kenya
Caregivers in this study believed the RTS,S/AS01 to be effective and were motivated to have their children vaccinated. Despite these positive perceptions of the malaria vaccine, uptake was substantially hindered by persistent health system constraints. Negative provider attitudes emerged as a powerful deterrent to attending immunisation services and hampered uptake of the vaccine. Strategies that focus on improving interpersonal communication ski…
Integrated delivery of family planning and childhood immunisation services
Evidence suggests that integrating family planning (FP) services with childhood immunisations can increase postpartum contraceptive use by providing timely contact with FP services during the year following childbirth. However, little is known about clients' experiences of FP services within this context. Systems thinking was applied to examine the responsiveness of FP services that were integrated with childhood immunisations in routine outreach…
Integrated delivery of family planning and childhood immunization services
Evidence from several countries in sub-Saharan Africa suggests that the integration of family planning (FP) with childhood immunization services can help reduce the unmet need for FP among postpartum women without undermining the uptake of immunizations. However, the quality and responsiveness of FP services that are integrated with childhood immunizations remain understudied. A qualitative study was conducted in two districts of Malawi, which ex…
Interventions to improve district-level routine health data in low-income and middle-income countries
What mechanisms drive uptake of family planning when integrated with childhood immunisation in Ethiopia? A realist evaluation
Linking context and intervention components to the mechanisms they triggered helped explain the intervention outcomes, and more broadly how and for whom the intervention worked. Linking empirical mechanisms to constructs of implementation related theoretical frameworks provided a level of abstraction through which findings could be cumulated across time, space, and conditions by theorising middle-range mechanisms
Adoption of evidence-based global policies at the national level
In 2012, the World Health Organization (WHO) updated its policy on intermittent preventive treatment in pregnancy with sulphadoxine–pyrimethamine (IPTp-SP). A global recommendation to revise the WHO policy on the treatment of malaria in the first trimester is under review. We conducted a retrospective study of the national policy adoption process for revised IPTp-SP dosing in four sub-Saharan African countries. Alongside this retrospective study,…
Competing interests, clashing ideas and institutionalizing influence
This article explores how malaria control in sub-Saharan Africa is shaped in important ways by political and economic considerations within the contexts of aid-recipient nations and the global health community. Malaria control is often assumed to be a technically driven exercise: the remit of public health experts and epidemiologists who utilize available data to select the most effective package of activities given available resources. Yet resea…
Understanding evidence use from a programmatic perspective
Background: Conceptualisations of what it means to use evidence in policymaking often appear divided between two extremes. On the one side are works presenting it as the implementation of research findings – particularly evaluations of intervention effect. In contrast stand theoretically informed works exploring the multiple meanings of evidence use, political complexities, and the constructed nature of research evidence itself. The first perspec…
Effectiveness of two community-based strategies on disease knowledge and health behaviour regarding malaria, diarrhoea and pneumonia in Ghana
Both iCCM and CHPS were associated with disease knowledge and health behaviour, but this was more pronounced for iCCM and in the Northern Region. HBC should continue to be considered as the strategy through which community-IMCI is implemented
The relative roles of ANC and EPI in the continuous distribution of LLINs
BACKGROUND: The continuous distribution of long-lasting insecticidal nets (LLINs) for malaria prevention, through the antenatal care (ANC) and the Expanded Programme on Immunizations (EPI), is recommended by the WHO to improve and maintain LLIN coverage. Despite these recommendations, little is known about the relative strengths and weaknesses of the ANC and EPI-based LLIN distribution. This study aimed to explore and compare the roles of the ANC…
Setting Priorities in Global Child Health Research Investments
This article provides detailed guidelines for the implementation of systematic method for setting priorities in health research investments that was recently developed by Child Health and Nutrition Research Initiative (CHNRI). The target audience for the proposed method are international agencies, large research funding donors, and national governments and policy-makers. The process has the following steps: (i) selecting the managers of the proce…
Delivery systems for insecticide treated and untreated mosquito nets in Africa
INTRODUCTION: Coverage of insecticide-treated nets (ITNs) in sub-Saharan Africa is still low despite their proven efficacy, effectiveness and cost-effectiveness. Delivery systems for ITNs have been hotly debated, but there has been no structured approach to assessing their relative effectiveness. This paper aims to: propose a categorization of ITN and mosquito net delivery systems; classify existing systems according to this categorization; criti…
