Introduction Pharmacovigilance (PV) systems to monitor drug and vaccine safety are often inadequate in sub-Saharan
Africa. In Malawi, a PV enhancement initiative was introduced to address major barriers to PV.
Objective The objective of this initiative was to improve reporting of adverse events (A
...
Es) by strengthening passive safety
surveillance via PV training and mentoring of local PV stakeholders and healthcare providers (HCPs) at their own healthcare
facilities (HCFs).
Methods An 18-month PV training and mentoring programme was implemented in collaboration with national stakeholders,
and in partnership with the Ministry of Health, GSK and PATH. Two-day training was provided to Expanded Programme on
Immunisation coordinators, identified as responsible for AE reporting, and four National Regulatory Authority representa-
tives. Abridged PV training and mentoring were provided regularly to HCPs. Support was given in upgrading the national
PV system. Key performance indicators included the number of AEs reported, transmission of AE forms, completeness of
reports, serious AEs reported and timeliness of recording into VigiFlow.
Results In 18 months, 443 HCPs at 61 HCFs were trained. The number of reported AEs increased from 22 (January 2000 to
October 2016) to 228 (November 2016 to May 2018), enabling Malawi to become a member of the World Health Organization
Programme for International Drug Monitoring. Most (98%) AE report forms contained mandatory information on reporter,
event, patient and product, but under 1% were transmitted to the national PV office within 48 h.
Conclusion Regular PV training and mentoring of HCPs were effective in enhancing passive safety surveillance in Malawi,
but the transmission of reports to the national PV centre requires further improvement.

Little is known about asthma control in the rising number of African children who suffer from this condition. The Achieving Control of Asthma in Children in Africa (ACACIA) study is an observational study collecting evidence about paediatric asthma in urban areas of Ghana, Malawi, Nigeria, South Afr
...
ica, Uganda and Zimbabwe. The primary objectives are: (1) to identify 3000 children aged between 12 years and 14 years with asthma symptoms; and (2) to assess their asthma control, current treatment, knowledge of and attitudes to asthma and barriers to achieving good control. Secondary objective is to develop interventions addressing identified barriers to good symptom control.
Each centre will undertake screening to identify 500 school children with asthma symptoms using questions from the Global Asthma Network’s questionnaire. Children identified to have asthma symptoms will fill in a digital survey, including: Asthma Control Test, questions on medication usage and adherence, medical care, the Brief-Illness Perception questionnaire and environmental factors. Exhaled nitric oxide testing and prebronchodilator and postbronchodilator spirometry will be performed. A subgroup of children will participate in focus group discussions. Results will be analysed using descriptive statistics and comparative analysis. Informed by these results, we will assess the feasibility of potential interventions, including the adaption of a UK-based theatre performance about asthma attitudes and digital solutions to improve asthma management.

The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. To reach this goal in children with asthma, ongoing monitoring is essential. While all components of asthma, such as symptoms, lung function, bronchial hyperresponsiveness and inflammation, may exist i

n various combinations in different individuals, to date there is limited evidence on how to integrate these for optimal monitoring of children with asthma. The aims of this ERS Task Force were to describe the current practise and give an overview of the best available evidence on how to monitor children with asthma.
22 clinical and research experts reviewed the literature. A modified Delphi method and four Task Force meetings were used to reach a consensus.
This statement summarises the literature on monitoring children with asthma. Available tools for monitoring children with asthma, such as clinical tools, lung function, bronchial responsiveness and inflammatory markers, are described as are the ways in which they may be used in children with asthma. Management-related issues, comorbidities and environmental factors are summarised.
Despite considerable interest in monitoring asthma in children, for many aspects of monitoring asthma in children there is a substantial lack of evidence.

owing and rescue bronchodilator use and thus reduce the risk of life-threatening exacerbations and long-term morbidity. The importance of including all aspects of control in the assessment of individual patients was emphasised by a recent factor analysis which showed that clinical asthma is composed of distinct components which are not closely correlated with each other.6 However, in some studies it may not be possible to collect airway calibre or short-acting β2-agonists data. Previous analysis of non-clinical trial data suggested that when ACQ scores are analysed as group data, the heterogeneity of the way in which individual patients present with inadequate control is lost in the estimation of the mean and the need to measure each individual component of asthma control may become unnecessary. In this analysis, ACQ data from a clinical trial was used to evaluate the measurement properties (reliability, responsiveness, validity and interpretability), of three shortened versions of the ACQ. In addition, we have examined whether the precision and accuracy of estimating the effect of the intervention on asthma control was maintained when the two questions concerning airway calibre and short-acting β2-agonists use were omitted from the trial analysis.

Several challenges face asthma management in Egypt, including the high percentage of uncontrolled patients, inadequate compliance, and overuse of short-acting beta-agonists (SABAs) leading to increased asthma-related morbidity and mortality. In this regard, the recent Global Initiative for Asthma (G

Asthma is the most common non-communicable disease in children and remains one of the most common throughout the life course. The great majority of the burden of this disease is seen in low-income and middle-income countries (LMICs), which have disproportionately high asthma-related mortality relati

ve to asthma prevalence. This is particularly true for many countries in sub-Saharan Africa. Although inhaled asthma treatments (particularly those containing inhaled corticosteroids) markedly reduce asthma morbidity and mortality, a substantial proportion of the children, adolescents, and adults with asthma in LMICs do not get to benefit from these, due to poor availability and affordability. In this review, we consider the reality faced by clinicians managing asthma in the primary and secondary care in sub-Saharan Africa and suggest how we might go about making diagnosis and treatment decisions in a range of resource-constrained scenarios. We also provide recommendations for research and policy, to help bridge the gap between current practice in sub-Saharan Africa and Global Initiative for Asthma (GINA) recommended diagnostic processes and treatment for children, adolescents, and adults with asthma.

Most of the global burden of sepsis occurs in low- and middle-income countries (LMICs), but the prevalence and etiology of sepsis in LMICs are not well understood. In particular, the lack of laboratory infrastructure in many LMICs has historically precluded an assessment of the pathogens leading to

sepsis. A recent systematic review found that data describing antimicrobial resistance were absent for 43% of countries in Africa, and only two countries have national antimicrobial resistance plans. In addition, small studies have identified indiscriminate antibiotic use both in and out of hospital settings in sub-Saharan Africa. The absence of microbiological data and lack of antibiotic stewardship complicate sepsis management and almost certainly worsens outcomes, particularly in low-resource systems. The purpose of this study was to examine the prevalence, etiology, and outcomes of sepsis among a cohort of critically ill patients in a referral hospital of Malawi, with a focus on the prevalence of culture-confirmed bacteremia and urinary tract infections.

But just h

ow much of health aid is cost-effective? In this paper, we examine projects in the Organisation for Economic Co-operation and Development (OECD) Creditor Reporting System, the standard dataset that measures and characterizes development assistance for health, for the
years 2019 to 2021, and count the number of projects that refer to interventions from a list of highly cost-effective interventions as defined by the Disease Control Priorities Project, third edition. This exploratory quantitative analysis indicates that 61% of projects used a key word/phrase of a costeffective intervention. There were 11.9 interventions mapped per project on average. There is little evidence that donors tailor the set of interventions to country income levels by cost-effectiveness.
Policymakers may benefit from reviewing the full portfolio of interventions covered by domestic and external resources.

space for health, the pursuit of efficiency gains and exploring innovative health financing for health seem attractive. This paper sought to synthesize available evidence on the nature of innovative health financing instruments, mechanisms and policies implemented in Africa. We further reviewed the factors that hinder or facilitate implementation, the lessons learnt on the structure, the development process and the implementation.

Rwanda’s mountainous topography makes ground transportation of medical supplies unreliable — some roads stretching into rural areas remain uncared for and unpaved. Between 25 and 40 per cent of all temperature-sensitive medical supplies sent from urban centres to rural health clinics are wasted

because of an unreliable cold-chain infrastructure. Rural clinics are also often subject to stockouts, and patients in need of specialized blood products, drugs and other supplies are unable to acquire them. Zipline, a US-based health logistics company, aims to address the issue of access to medical supplies, largely leapfrogging traditional modes of transportation and various obstacles. Zipline uses drones to deliver blood and other routine and emergency medical supplies from distribution centres to district hospitals and rural health centres.
Although the company has been celebrated in the media for its operations, there is little scholarly work on its operations and performance. This has led to some confusion over its scale. We aimed to gain insight into the details of Zipline’s business model, including the infrastructure, regulations and government support that make Zipline possible, and to understand its impact on health outcomes in Rwanda. Our work was entirely based on published materials since our research was conducted during the COVID-19 pandemic.
