Barriers to prompt and effective malaria treatment among the poorest population in Kenya

Antiplasmodial potential of compounds isolated from Ziziphus mucronata and their binding to Plasmodium falciparum HGXPRT using biophysical and molecular docking studies

The increasing resistance of Plasmodium parasites to currently available antiplasmodial therapies poses a significant challenge in treating malaria. Since ancient times, plants have served as a primary source of novel pharmacologically active compounds for drug development. Therefore, this study aimed to explore the antiplasmodial properties of pentacyclic triterpenes isolated from Ziziphus mucronata bark, with an emphasis on their mechanism of action. Dichloromethane and ethyl acetate extracts of the stem bark were subjected to silica gel column chromatography, which led to the isolation of three known triterpenoids: betulinic acid, methyl betulinate, and lupeol. The compounds were then evaluated for antiplasmodial activity against Plasmodium falciparum NF54 strains using the Plasmodium lactate dehydrogenase (pLDH) assay. In silico evaluation of the isolated compounds was conducted through molecular docking and further validated with in vitro experiments against a purified protein target, Plasmodium falciparum hypoxanthine-guanine-xanthine phosphoribosyltransferase (PfHGXPRT). Betulinic acid, methyl betulinate, and lupeol exhibited potent antiplasmodial activities with IC50 values of 20, 10.11, and 7.56 µg/mL, respectively. Lupeol exhibited the highest binding energy of - 7.6 kcal/mol. Differential scanning fluorimetry revealed that lupeol decreases the Tm of PfHGXPRT, thus decreasing the protein's thermal stability. At high concentrations, lupeol also increased protein absorbance, indicating the detection of hydrophobic amino acids and protein unfolding. This study proves that Z. mucronata could serve as a reservoir of effective agents for treating malaria, while also scientifically validating its use in traditional medicine. However, further experimental studies are required to substantiate its relevant therapeutic effects.

Who benefits from the donor-supported malaria programme in Enugu State, Nigeria? A benefit incidence analysis

Nigeria bears the highest global burden of malaria, accounting for 25% of cases and 19% of deaths worldwide. Development partners provide substantial support for malaria prevention and treatment in Nigeria. This study examines the financial burden of malaria on households and the benefit incidence of donor-supported bed net services in Enugu State, Nigeria. We conducted an interview-administered household survey in urban, semi-urban and rural regions in Enugu State in 2020. We collected data on the use of malaria services and out-of-pocket (OOP) payments. Socioeconomic status (SES) was estimated using household assets ownership. The benefits of malaria services were calculated by multiplying the unit cost of services while the net benefit was calculated by subtracting OOP payment from the benefits. A concentration index was used to assess equity in spending on malaria across socioeconomic quintiles. We estimated the gross and net benefit incidences for malaria services by deducting the OOP payment from the gross benefits. Most respondents were women, married, and had attained secondary education. Over 53.9% of surveyed households owned bed net. About 31.6% of households used malaria drugs in the past months. All users paid OOP for malaria drugs, sprays and lab services and over one-third of households incurred OOP costs for bed nets. The total OOP expenditure for malaria in the past month was $0.53 per household. The gross benefit incidence for malaria services was $1836.7. The net benefit and donor benefit were $1679.5 and $705.4, respectively. Both gross and net benefit for malaria services favored less-poor households. Households in Enugu State incur OOP expenses for malaria diagnosis and treatment, and less-poor households benefit more from government- and donor- subsidized malaria services, including bed nets. It is imperative to improve the accessibility and affordability of malaria diagnosis and treatment in Nigeria to ensure equitable access to malaria services.

How much could health worker absenteeism impact health outcomes? A modeling study of malaria in Kenya

When health workers are not at their posts, health care does not happen. Health worker absenteeism in Kenya was 53.8% in 2018 according to the World Bank Service Delivery Indicators Survey. Absenteeism is especially impactful for treatment of malaria where delays in treatment can lead to deadly consequences especially among the most vulnerable. Human resources management and development strengthening interventions using digital tools like iHRIS, IntraHealth International's open-source, human resource information system, can enable data-driven decision making to plan and budget for health workers and dynamically redistribute them. These promising approaches can reduce systemic absenteeism, but little is known how much impact reduced absenteeism can have on health outcomes. In this study, the Spectrum Malaria tool, a dynamic malaria transmission model developed by Avenir Health, was used to test three scenarios of reduced absenteeism (5, 10 and 15%) to quantify the potential impact of absenteeism on malaria cases and deaths averted and Plasmodium falciparum (P. falciparum) prevalence among children ages 2-9 years in Kenya between 2023 and 2030. A small, 5% increase in effective coverage of treatment of uncomplicated cases of malaria with artemisinin combination therapy could result in a 12% decrease in uncomplicated cases, a 15% reduction in severe cases, and a 13% reduction in deaths among the population and a 24% reduction in P. falciparum prevalence among children aged 2-9 years. Stemming health worker absenteeism is a critical intervention in the fight against malaria and digital tools like iHRIS for health workforce planning can help reduce absenteeism.

RESUMEN

Cuando los prestadores de salud no están en sus puestos, el cuidado de la salud no ocurre. El ausentismo entre los prestadores de salud en Kenia fue de 53.8% en 2018, según las encuestas de los Indicadores de Prestación de Servicios (IPS) del Banco Mundial. Ausentismo como este entraña un impacto especialmente fuerte en el tratamiento de la malaria, donde la demora puede tener consecuencias letales, especialmente entre los más vulnerables. Intervenciones con herramientas digitales que fortalecen la gestión y desarrollo de recursos humanos, como iHRIS (el sistema de información de recursos humanos de código abierto de IntraHealth International), hacen posible tomar decisiones basadas en datos en torno a la planificación y presupuestación de la fuerza laboral de prestadores de salud y a cómo distribuirla de forma dinámica. Estos prometedores enfoques pueden reducir el ausentismo sistémico, pero se sabe poco acerca del tamaño del impacto que esta reducción puede tener en los resultados de salud. En este estudio usamos Spectrum-Malaria (un modelo dinámico de transmisión de la malaria, desarrollado por Avenir Health) como herramienta para examinar tres escenarios de ausentismo reducido (del 5, 10, y 15%) a fin de cuantificar el impacto potencial del ausentismo sobre el número de casos y fallecimientos evitados, y la prevalencia de Plasmodium falciparum (P. falciparum) en niños de 2-9 años de edad en Kenia entre 2023 y 2030. Un incremento pequeño, de 5%, en la cobertura efectiva de casos de malaria con tratamientos combinados con artemisinina (TCA), podría resultar en una reducción de 12% en el número de casos sin complicaciones, una reducción de 15% en los casos severos, y una reducción de 13% en el número de muertes entre la población, además de suponer una reducción de 24% en la prevalencia de P. falciparum en niños de 2-9 años de edad. Restringir el ausentismo de los prestadores de salud es una intervención crítica en la lucha contra la malaria, y el uso de herramientas digitales de planificación de la fuerza laboral, como iHRIS, puede ayudar a reducir este ausentismo.

RESUMO

Quando os profissionais de saúde não estão nos seus postos, os cuidados de saúde não são prestados O absentismo dos profissionais de saúde no Quénia foi de 53,8% em 2018, de acordo com o Inquérito de Indicadores de Prestação de Serviços do Banco Mundial. O absentismo tem um impacto especial no tratamento da malária, onde os atrasos no tratamento podem ter consequências mortais, especialmente entre os mais vulneráveis. As intervenções de gestão de recursos humanos e de reforço do desenvolvimento que utilizam ferramentas digitais como o iHRIS, o sistema de informação de recursos humanos de fonte aberta da IntraHealth International, podem permitir a tomada de decisões baseadas em dados para planear e orçamentar os profissionais de saúde e redistribuí-los dinamicamente. Estas abordagens promissoras podem reduzir o absentismo sistémico, mas pouco se sabe sobre o impacto que a redução do absentismo pode ter nos resultados sanitários. Neste estudo, a ferramenta Spectrum Malaria, um modelo dinâmico de transmissão da malária desenvolvido pela Avenir Health, foi utilizada para testar três cenários de redução do absentismo (5, 10 e 15%), para quantificar o impacto potencial do absentismo nos casos de malária e mortes evitadas e na prevalência de Plasmodium falciparum (p falciparum) entre crianças dos 2 aos 9 anos de idade no Quénia entre 2023 e 2030. Um pequeno aumento de 5% na cobertura efectiva do tratamento de casos não complicados de malária com ACT poderia resultar numa diminuição de 12% nos casos não complicados, numa redução de 15% nos casos graves e numa redução de 13% nas mortes entre a população, bem como numa redução de 24% na prevalência de p falciparum entre crianças dos 2 aos 9 anos de idade. Travar o absentismo dos profissionais de saúde é uma intervenção fundamental na luta contra a malária e ferramentas digitais como o iHRIS para o planeamento da força de trabalho no sector da saúde podem ajudar a reduzir o absentismo.

RÉSUMÉ

Lorsque les agents de santé ne sont pas à leur poste, les soins de santé ne sont pas dispensés. L'absentéisme des agents de santé au Kenya était de 53,8% en 2018, selon l'enquête sur les Indicateurs de prestation de services de la Banque mondiale. L'absentéisme a un impact particulièrement important pour le traitement du paludisme, où les retards dans le traitement peuvent avoir des conséquences mortelles, en particulier parmi les plus vulnérables. Les interventions de renforcement de la gestion et du développement des ressources humaines utilisant des outils numériques comme iHRIS, le système d'information sur les ressources humaines open source d'IntraHealth International, peuvent permettre une prise de décision fondée sur les données pour planifier et budgétiser la gestion des agents de santé et les redistribuer de manière dynamique. Ces approches prometteuses peuvent réduire l'absentéisme systémique, mais on sait peu de choses sur l'impact qu'une réduction de l'absentéisme peut avoir sur les résultats de santé. Dans cette étude, l'outil Spectrum Malaria, un modèle dynamique de transmission du paludisme développé par Avenir Health, a été utilisé pour tester trois scénarios de réduction de l'absentéisme (5, 10 et 15%) afin de quantifier l'impact potentiel de l'absentéisme sur les cas de paludisme et les décès évités. et sur la prévalence de Plasmodium falciparum (P. falciparum) chez les enfants âgés de 2 à 9 ans au Kenya entre 2023 et 2030. Une légère augmentation de 5% de la couverture efficace du traitement des cas de paludisme non compliqués par l'ACT pourrait entraîner une diminution de 12% de ceux-ci, une réduction de 15% des cas graves et une réduction de 13% des décès au sein de la population, ainsi qu'une réduction de 24% de la prévalence de P. falciparum chez les enfants âgés de 2 à 9 ans. Réduire l'absentéisme des agents de santé est une intervention essentielle dans la lutte contre le paludisme et les outils numériques comme iHRIS pour la planification des personnels de santé peuvent contribuer à réduire l'absentéisme.

Prevalence of unqualified sources of antimalarial drug prescription for children under the age of five: A study in 19 low- and middle-income countries

BACKGROUND

Antimalarial drug resistance poses a severe danger to global health. In Low- and Middle-Income Countries (LMICs), there is a lack of reliable information on antimalarial prescriptions for recent malarial fever in children under five. Our study aims to determine the prevalence of unqualified sources of antimalarial drug prescription for children under the age of five in 19 low- and middle-income countries.

METHODS

We performed a cross-sectional study of the Malaria Indicator Survey (MIS) datasets (n = 106265) across 19 LMICs. The recent MIS datasets were used, and the study only included children under five who had taken an antimalarial drug for a recent malarial fever. The outcome variable was classified into two distinct categories: those who had taken antimalarial drugs for malarial fever from qualified sources and those who did not.

FINDINGS

Among LMICs, we found that 87.1% of children under five received an antimalarial prescription from unqualified sources who had recently experienced malarial fever. In several LMICs (Tanzania, Nigeria, and Ghana), a substantial portion of recent antimalarial prescriptions for malaria was taken from unqualified sources (about 60%). Some LMICs (Guinea (31.8%), Mali (31.3%), Nigeria (20.4%), Kenya (2.6%), and Senegal (2.7%)) had low rates of antimalarial drug consumption even though children under five received a high percentage of antimalarial prescriptions from qualified sources for a recent malarial fever. Living in rural areas, having mothers with higher education, and having parents with more wealth were frequently taken antimalarial from qualified sources for recent malarial fever in children under five across the LMICs.

INTERPRETATION

The study draws attention to the importance of national and local level preventative strategies across the LMICs to restrict antimalarial drug consumption. This is because antimalarial prescriptions from unqualified sources for recent malarial fever in children under five were shockingly high in most LMICs and had high rates of unqualified prescriptions in certain other LMICs.

The Malaria Burden: A South African Perspective

Malaria is a deadly disease caused by protozoan pathogens of the Plasmodium parasite. Transmission to humans occurs through the bite of an infected female Anopheles mosquito. According to the World Health Organization (WHO), an estimated 247 million cases of malaria were recorded worldwide in 2021, with approximately 619 000 malaria deaths. The initial signs of malaria can be mild and challenging to diagnose due to the signs and symptoms being similar to those of other illnesses. The malaria burden remains largely concentrated in the WHO sub-Saharan African region and has been recognised as a significant contributor to morbidity and mortality. This review aims to contribute to the existing knowledge on malaria in South Africa, a region within sub-Saharan Africa, focusing on the epidemiology and life cycle of the malaria parasite as well as diagnostic approaches for detecting malaria. In addition, nonpharmacological and pharmacological interventions for treating and preventing malaria infections will also be discussed herein. While there has been a significant reduction in the global burden of this disease, malaria remains a public health issue in South Africa. As such, the implementation of effective preventative measures and strategies, early diagnosis, and appropriate treatment regimens are crucial to reducing the malaria burden in South Africa.

Examining the disparities of anti-malarial drug consumption among children under the age of five: a study of 5 malaria-endemic countries

BACKGROUND

Malaria is one of the most prominent illnesses affecting children, ranking as one of the key development concerns for many low- and middle-income countries (LMICs). There is not much information available on the use of anti-malarial drugs in LMICs in children under five. The study aimed to investigate disparities in anti-malarial drug consumption for malaria among children under the age of five in LMICs.

METHODS

This study used recent available cross-sectional data from the Malaria Indicator Survey (MIS) datasets across five LMICs (Guinea, Kenya, Mali, Nigeria, and Sierra Leone), which covered a portion of sub-Saharan Africa. The study was carried out between January 2, 2023, and April 15, 2023, and included children under the age of five who had taken an anti-malarial drug for malaria 2 weeks before the survey date. The outcome variable was anti-malarial drug consumption, which was classified into two groups: those who had taken anti-malarial drugs and those who had not.

RESULTS

In the study of LMICs, 32,397 children under five were observed, and among them, 44.1% had received anti-malarial drugs. Of the five LMICs, Kenya had the lowest (9.2%) and Mali had the highest (70.5%) percentages of anti-malarial drug consumption. Children under five with malaria are more likely to receive anti-malarial drugs if they are over 1 year old, live in rural areas, have mothers with higher education levels, and come from wealthier families.

CONCLUSION

The study emphasizes the importance of developing universal coverage strategies for anti-malarial drug consumption at both the national and local levels. The study also recommends that improving availability and access to anti-malarial drugs may be necessary, as the consumption of these drugs for treating malaria in children under the age of five is shockingly low in some LMICs.

Malaria diagnosis in rural healthcare facilities and treatment-seeking behavior in malaria endemic settings in western Kenya

Accurate malaria diagnosis and timely treatment are requirements for effective management of the disease. However, treatment efficacy may be significantly reduced in resource-constrained healthcare facilities with poorly equipped laboratories and frequent drug and rapid diagnostic test kit (RDT) stock-outs. Furthermore, patient may avoid seeking treatment from such facilities. The study's goal was to determine treatment-seeking behavior, malaria diagnosis and treatment quality, and likely treatment-seeking determinants in the local population. Passive case detection, which targeted all patients with suspected malaria cases, was conducted in ten public healthcare facilities over a three-month period. Monthly malaria cases, methods of diagnosis and antimalarial drug availability were assessed. A household-based survey was also carried out. Structured questionnaires were used to collect knowledge, attitude and practice (KAP) data from household heads. Malaria knowledge, treatment seeking behavior, and predictors of malaria treatment-seeking were all determined. Three of the seven dispensaries lacked a laboratory to conduct microscopy- diagnosis. These three dispensaries also experienced frequent RDT stock-outs, which resulted in depending on clinical signs as diagnosis for malaria. The majority of local residents with fever (50.3%) purchased antimalarial drugs from a chemist. About 37% of fever patients sought treatment at healthcare facility while the remaining 12.7% did not treat their fevers. In irrigated areas, 45.5% (46/64) of fever patients sought treatment at healthcare facilities, compared to 25% (18/64) in non-irrigated areas (p = 0.009). Most children aged below 5 who had fever (77.7%) were taken to healthcare facility for treatment compared to 31.4% of children aged 5-14 years or 20.9% of adults (0.0001). Predictors of treatment seeking included access to healthcare facility (OR = 16.23, 95% CI: 2.74-96.12), and ability to pay hospital bills (OR = 10.6, 95% CI: 1.97-57). Other factors that influenced health-seeking behavior included the severity of symptoms, the age of the patient and knowledge of malaria symptoms.

Perceptions on use of insecticide-treated bed nets to prevent malaria: a qualitative assessment in two rural districts of Zambézia province in Mozambique

Background

Malaria prevention in Africa merits particular attention as the world strives toward a better life for the poorest. The insecticide-treated bed nets (ITNs) are one of the malaria control strategies that, due to their cost effectiveness, are largely used in the country. Data on the actual coverage and usage of bed nets is unreliable, as it is based only on administrative data from distributed ITNs.

Objective

This study assesses knowledge about malaria and bed net use in two areas of high malaria transmission.

Methods

A qualitative study was conducted in 6 (six) rural communities in two malaria high-burden districts in Zambézia province. About 96 adults were recruited from the communities and enrolled to participate in focus group discussions. Data were transcribed verbatim, coded, and thematically analyzed using Nvivo11.0.

Results

Participants mentioned the mosquito as the only cause of malaria and that the use of bed nets was highlighted as the most proficient protection against mosquito bites and malaria. Children and pregnant women were described as being the priority groups to sleep under a bed net protection in the household. The use of bed nets was common among households, although not sufficient for the number of household members. In addition, the preservation of the nets was considered inadequate.

Conclusions

The findings of this study highlight the need to increase public knowledge about malaria and nets and to strengthen the communication and logistics component of the net distribution campaign to ensure that households have enough nets for their members and use them appropriately.

Reliability and validity of an innovative high performing healthcare system assessment tool

BACKGROUND

Universal Health coverage (UHC) is the mantra of the twenty-first century yet knowing when it has been achieved or how to best influence its progression remains elusive. An innovative framework for High Performing Healthcare (HPHC) attempts to address these issues. It focuses on measuring four constructs of Accountable, Affordable, Accessible, and Reliable (AAAR) healthcare that contribute to better health outcomes and impact. The HPHC tool collects information on the perceived functionality of health system processes and provides real-time data analysis on the AAAR constructs, and on processes for health system resilience, responsiveness, and quality, that include roles of community, private sector, as well as both demand, and supply factors affecting health system performance. The tool attempts to capture the multidimensionality of UHC measurement and evidence that links health system strengthening activities to outcomes. This paper provides evidence on the reliability and validity of the tool.

METHODS

Internet survey with non-probability sampling was used for testing reliability and validity of the HPHC tool. The volunteers were recruited using international networks and listservs. Two hundred and thirteen people from public, private, civil society and international organizations volunteered from 35 low-and-middle-income countries. Analyses involved testing reliability and validity and validation from other international sources of information as well as applicability in different setting and contexts.

RESULTS

The HPHC tool's AAAR constructs, and their sub-domains showed high internal consistency (Cronbach alpha >.80) and construct validity. The tool scores normal distribution displayed variations among respondents. In addition, the tool demonstrated its precision and relevance in different contexts/countries. The triangulation of HPHC findings with other international data sources further confirmed the tool's validity.

CONCLUSIONS

Besides being reliable and valid, the HPHC tool adds value to the state of health system measurement by focusing on linkages between AAAR processes and health outcomes. It ensures that health system stakeholders take responsibility and are accountable for better system performance, and the community is empowered to participate in decision-making process. The HPHC tool collects and analyzes data in real time with minimum costs, supports monitoring, and promotes adaptive management, policy, and program development for better health outcomes.

Self-Reported Symptoms at Last Febrile Illness as a Predictor of Treatment-Seeking in Western Kenya: A Cross-Sectional Study

Timely treatment-seeking behavior can reduce morbidity and mortality due to infectious diseases. Patterns of treatment-seeking behavior can differ by access to health care, and perceptions of disease severity and symptoms. We evaluated the association between self-reported symptoms at last illness and the level of treatment-seeking behaviors. We analyzed cross-sectional data from 1,037 participants from the lowlands and highlands of Western Kenya from 2015 using logistic regression models. There was considerable heterogeneity in the symptoms and treatment-seeking behaviors reported among individuals who were febrile at their last illness. A greater number of self-reported categories of symptoms tended to be associated with a higher likelihood of treatment-seeking in both sites. Participants were significantly more likely to seek treatment if they reported fever, aches, and digestive symptoms at last illness than just fever and aches or fever alone, but the frequency of treatment-seeking for fever in combination with aches and respiratory symptoms did not follow a consistent pattern. Among those who sought treatment, most used a formal source, but the patterns were inconsistent across sites and by the number of symptoms categories. Understanding the drivers of treatment-seeking behavior after febrile illness is important to control and treat infectious diseases in Kenya.

Choice of health providers and health-seeking behaviour among forest goer population in Myanmar: findings from a cross-sectional household survey

BACKGROUND

In Myanmar, malaria still poses a significant burden for vulnerable populations particularly forest goers even though impressive progress has been made over the past decade. Limited evidence existed related to forest goers' health-seeking behaviour and factors that drive decision making for providers' choice to support national malaria programmes towards elimination. In response to that, this research is conducted to identify who they preferred and what are the factors associated with providers' choice in malaria febrile illness and Rapid Diagnostic Testing (RDT).

METHODS

A cross-sectional study applying quantitative household survey was completed with 479 forest goer households in 20 malaria endemic townships across Myanmar. The household data was collected with the types of providers that they consulted for recent and previous febrile episodes. To identify the factors associated with providers' choices, univariate and multivariate multinomial logistic regressions were done using Stata version 14.1. Statistical significance was set as p = 0.05.

RESULTS

A total of 307 individuals experienced fever within one month and 72.3% sought care from providers. Also, a total of 509 forest goers reported that they had a previous febrile episode and 62.6% received care from a provider. Furthermore, 56.2% said that they had RDT testing during these previous febrile illnesses. They consulted public facilities and public health staff, private facilities, private and semi-private providers, community health volunteers or workers in their residing village and those located outside their villages but majority preferred those within their villages. On multivariate analyses, second richest quintile (public, RRR = 12.9) (semi-private, RRR = 17.9), (outside, RRR = 8.4) and access to 4 and above nearby providers (public, RRR = 30.3) (semi-private, RRR = 1.5) (outside, RRR = 0.5) were found to be significantly associated with provider choice for recent fever episode. Similar findings were also found for previous febrile illness and RDT testing among forest goers.

CONCLUSIONS

It was highlighted in this study that in forest goer households, they preferred nearby providers and the decision to choose providers seemed to be influenced by their access to number of nearby providers and socio-economic status when they sought care from a provider regardless of fever occurrence location. It was important that the national programmes considere involving these nearby providers in elimination efforts.

Developing and implementing National Health Insurance: learnings from the first try in Benin

In 2008, Benin government launched a national health insurance scheme, but this had been suspended in 2017. We aim to understand how existing ideas and institutions, stakeholders' behaviour and their interests shaped policy-making process and policy content, from its launch to its suspension.

METHODS

We used a case study design, framed by the policy triangle of Walt and Gilson. We collected data through document review, quantitative data extraction from routine information, and interviews with 20 key informants. We performed a content analysis using both complementarily deductive and inductive analysis.

RESULTS

This study confirms the keen interest for national health insurance scheme in Benin among various stakeholders. Compared with user fee exemption policies, it is considered as more sustainable, with a more reliable financing, and a greater likelihood to facilitate population's access to quality healthcare without financial hardships.Exempting the poor from paying health insurance premiums was however considered as an equitable mean to facilitate the extension of the health insurance to informal sector workers.The whole arrangements failed to deliver appropriate skills, tools, coordination and incentives to drive the policy implementers to make individual and organisational changes necessary to adjust to the objectives and values of the reform. These deficiencies compromised the implementation fidelity with unintended effects such as low subscription rate, low services utilisation and sustainability threats.

CONCLUSION

Supporting countries in documenting policy processes will ease learning across their tries for progressing towards Universal Health Coverage, as more than one try will be necessary.

Ethical considerations in deploying triple artemisinin-based combination therapies for malaria: An analysis of stakeholders’ perspectives in Burkina Faso and Nigeria

Background

Artemisinin-based combination therapies (ACTs) are the recommended treatment for uncomplicated Plasmodium falciparum malaria in all malaria endemic countries. Artemisinin resistance, partner drug resistance, and subsequent ACT failure are widespread in Southeast Asia. The more recent independent emergence of artemisinin resistance in Africa is alarming. In response, triple artemisinin-based combination therapies (TACTs) are being developed to mitigate the risks associated with increasing drug resistance. Since ACTs are still effective in Africa, where malaria is mainly a paediatric disease, the potential deployment of TACTs raises important ethical questions. This paper presents an analysis of stakeholders’ perspectives regarding key ethical considerations to be considered in the deployment of TACTs in Africa provided they are found to be safe, well-tolerated and effective for the treatment of uncomplicated malaria.

Methods

We conducted a qualitative study in Burkina Faso and Nigeria assessing stakeholders’ (policy makers, suppliers and end-users) perspectives on ethical issues regarding the potential future deployment of TACTs through 68 in-depth interviews and 11 focus group discussions.

Findings

Some respondents suggested that there should be evidence of local artemisinin resistance before they consider deploying TACTs, while others suggested that TACTs should be deployed to protect the efficacy of current ACTs. Respondents suggested that additional side effects of TACTs compared to ACTs should be minimal and the cost of TACTs to end-users should not be higher than the cost of current ACTs. There was some disagreement among respondents regarding whether patients should have a choice of treatment options between ACTs and TACTs or only have TACTs available, while ACTs are still effective. The study also suggests that community, public and stakeholder engagement activities are essential to support the introduction and effective uptake of TACTs.

Conclusion

Addressing ethical issues regarding TACTs and engaging early with stakeholders will be important for their potential deployment in Africa.

Review of the Current Landscape of the Potential of Nanotechnology for Future Malaria Diagnosis, Treatment, and Vaccination Strategies

Malaria eradication has for decades been on the global health agenda, but the causative agents of the disease, several species of the protist parasite Plasmodium, have evolved mechanisms to evade vaccine-induced immunity and to rapidly acquire resistance against all drugs entering clinical use. Because classical antimalarial approaches have consistently failed, new strategies must be explored. One of these is nanomedicine, the application of manipulation and fabrication technology in the range of molecular dimensions between 1 and 100 nm, to the development of new medical solutions. Here we review the current state of the art in malaria diagnosis, prevention, and therapy and how nanotechnology is already having an incipient impact in improving them. In the second half of this review, the next generation of antimalarial drugs currently in the clinical pipeline is presented, with a definition of these drugs' target product profiles and an assessment of the potential role of nanotechnology in their development. Opinions extracted from interviews with experts in the fields of nanomedicine, clinical malaria, and the economic landscape of the disease are included to offer a wider scope of the current requirements to win the fight against malaria and of how nanoscience can contribute to achieve them.

Factors impacting test-based management of suspected malaria among caregivers of febrile children and private medicine retailers within rural communities of Fanteakwa North District, Ghana

Background

Prompt diagnosis and treatment prevents a mild case of malaria from developing into severe disease and death. Unfortunately, parasitological testing of febrile children is greater in the public and formal private sector than in the informal private sector in sub-Saharan Africa.

Methods

A mixed method study was carried out to determine factors limiting test-based management of suspected malaria cases among caregivers of febrile children and Over-the-Counter medicine sellers (OTCMS) in eight rural communities in Ghana. Structured questionnaires were used to interview 254 adult caregivers. Fourteen in-depth interviews were conducted with OTCMS. The interviews were audio-recorded, transcribed verbatim, and analysed thematically.

Results

The most frequently sought health providers by caregivers of febrile children in descending order were Community Health-Based Planning Services (CHPS) compounds; drug vendors; and OTCMS. Malaria parasitological testing rate of febrile children was highest (94.9%) at the CHPS compound and lowest (10.5%) at the OTCMS shops. Proportion of febrile children not subjected to malaria blood test is 28.3%. Among caregivers who did not ask for malaria blood test, 15.2% reported that healthcare provider did not offer a malaria blood test; 21.7% were financially handicapped to visit the Health Centre; and 63% lacked knowledge of malaria blood test and where to get it. From OTCMS point of view, clients’ inability to pay for malaria blood test, community perception that OTCMS are unqualified to perform malaria blood test, financial loss when unused RDT kits expires, clients’ demand for half dose of ACT, and activities of drug peddlers are factors limiting adherence to WHO recommended policy on testing before treating uncomplicated malaria cases.

Conclusion

The study results suggest the need to implement community friendly interventions aimed at improving test-based management of suspected malaria in febrile children. These may include educating caregivers and community members on the need to test and confirm malaria in febrile children before treating them, and supply of subsidized RDT kits to OTCMS and re-training them to provide testing services to their clients. Further studies pertaining to influence of gender roles on healthcare seeking attitude for febrile children is also suggested.

Sub-national disparities in accessing anti-malarial drug treatment in eastern Indonesia

BACKGROUND

Poor access to health care providers was among the contributing factors to less prompt and ineffective malaria treatment. This limitation could cause severe diseases in remote areas. This study examined the sub-national disparities and predictors in accessing anti-malarial drug treatment among adults in Eastern Indonesia.

METHODS

The study analyzed a subset of the 2018 National Basic Health Survey conducted in all 34 provinces in Indonesia. We extracted socio-demographic data of 4655 adult respondents diagnosed with malaria in the past 12 months in five provinces in Eastern Indonesia. The association between socio-demographic factors and the access to anti-malarial drug treatment was assessed using logistic regression.

RESULTS

Over 20% of respondents diagnosed with malaria within last 12 months admitted that they did not receive anti-malarial drug treatment (range 12-29.9%). The proportion of untreated cases was 12.0% in East Nusa Tenggara, 29.9% in Maluku, 23.1% in North Maluku, 12.7% in West Papua, and 15.6% in Papua. The likelihood of receiving anti-malarial drug treatment was statistically lower in Maluku (adjusted OR = 0.258; 95% CI 0.161-0.143) and North Maluku (adjusted OR = 0.473; 95% CI 0.266-0.840) than those in Eastern Nusa Tenggara (reference). Urban respondents were less likely to receive malaria treatment than rural (adjusted OR = 0.545; 95% CI 0.431-0.689).

CONCLUSIONS

This study found that there were sub-national disparities in accessing anti-malarial drug treatment in Eastern Indonesia, with a high proportion of untreated malaria cases across the areas. Findings from this study could be used as baseline information to improve access to anti-malarial drug treatment and better target malaria intervention in Eastern Indonesia.

Undernutrition and malaria among under-five children: findings from the 2018 Nigeria demographic and health survey

Malaria and undernutrition have independently contributed to mortality and morbidity among the under-five population of Nigeria. However, there remains complexity in their association. This study evaluates the association between stunting, underweight, wasting, and malaria among under-five Nigerian children while assessing the effects of sociodemographic factors. Cross-sectional data from the 2018 Nigeria Demographic and Health Survey were used, which included a study population of 12,996 children aged 0-59 months. Stunting (HAZ<-2.0 SD), underweight (WAZ<-2.0 SD), wasting (WHZ<-2.0 SD), malaria test results, and sociodemographic factors were obtained and examined. Logistic regression modeling was used to determine the associations between undernutrition, malaria, and sociodemographic factors. The prevalence of stunting was 37.0%, with 22.0% underweight, 6.9% wasting, and 22.6% tested positive for malaria. Stunting was frequent among 24-35 months old, 12-23 months old were mostly underweight and wasted, and 48-59 months old frequently suffered from malaria. Undernutrition and malaria frequently occurred among males, residents of rural areas, the poorest wealth quintile, and children of mothers with no formal education. The odds of having malaria was 89% higher among under-five stunted children (AOR = 1.89, 95% CI = 1.00,1.40; p-value = <0.0001). However, underweight (AOR = 1.11, 95% CI = 0.91,1.36; p-value = 0.2982) and wasting (AOR = 0.89, 95% CI = 0.67,1.19; p-value = 0.4519) were not significantly associated with malaria. The development of appropriate strategies, especially in rural areas and for less-educated mothers are critical to combat undernutrition and malaria.

Ethical, Regulatory and Market related aspects of Deploying Triple Artemisinin-Based Combination Therapies for Malaria treatment in Africa: A study protocol

Introduction: According to the World Malaria Report 2019, Africa accounts for 94% of the global malaria deaths. While malaria prevalence and mortality have declined over the years, recent reports suggest that these gains may stand the risk of being reversed if resistance to Artemisinin Combination Therapies (ACTs) spreads from Southeast Asia to Africa. Efforts are being made to develop new treatments that will address the looming threat of ACT resistance, including the development of triple artemisinin combination therapies (TACTs). The proposed study seeks to explore the views of stakeholders on the key ethical, regulatory and market-related issues that should be considered in the potential introduction of triple artemisinin combination therapies (TACTs) in Africa. Methods: The study employed qualitative research methods involving in-depth interviews and focus group discussions (FGDs) with stakeholders, who will be directly affected by the potential deployment of triple artemisinin combination treatments, as regulators, suppliers and end-users. Participants will be purposively selected and will include national regulatory authorities, national malaria control programs, clinicians, distributors and retailers as well as community members in selected districts in Burkina Faso and Nigeria. Discussion: The proposed study is unique in being one of the first studies that seeks to understand the ethical, social, regulatory and market position issues prior to the development of a prospective antimalarial medicine.

The Relationship Between Market Environment Dimensions and Availability of Malaria Pills in Uganda

Introduction

This study sought to examine the contribution of relationship building (in terms of collaboration, information sharing and supply chain interdependence) on the availability of malaria treatment pills in public hospitals in Sub-Saharan Africa using data from Uganda.

Methods

By means of a cross-sectional survey research design, the study used a questionnaire strategy to collect quantitative data. Out of the 320 questionnaires that were distributed in 40 public hospitals, 283 were answered and returned, which yielded an 88% response rate. Structural equation modelling (SEM) was used to establish the relationship between measured variables and latent constructs.

Results

Drawing on the survey results, the confirmatory factor analysist and the Structural Equation Modelling clearly demonstrate that relationship building (in terms of collaboration, information sharing and supply chain interdependence) significantly influences the availability of Artemisinin-based combination therapies in public general hospitals in Uganda.

Conclusion

Policy-makers should focus on developing cheaper information technology tools to exchange information regarding stock levels, forecasting, quantification, orders, and dispensing. This study developed a measurement model for an inter-hospital relationship, using relational view theory, and it employs dimensions in terms of information sharing and supply chain interdependence to predict and explain the availability of malaria pills in government hospitals.

Strengthening community and stakeholder participation in the implementation of integrated vector management for malaria control in western Kenya: a case study

Background

Integrated vector management (IVM) is defined as a rational decision-making process for the optimal use of resources for vector control. The IVM approach is based on the premise that effective control of vectors and the diseases they transmit is not the sole preserve of the health sector. It requires the collaboration and participation of communities and other stakeholders in public and private sectors. Community participation is key to the success of IVM implementation at the local level.

Case description

The study was conducted in Nyabondo, a rural area of Kenya where malaria is endemic. The objective of the project was to promote adoption and sustainability of IVM and scale up IVM-related activities as well as increase community participation and partnership in malaria control through outreach, capacity-building and collaboration with other stakeholders in the area. Collaboration was pursued through forging partnership with various government departments and ministries, particularly the fisheries department, ministry of education, ministry of health, forestry department and the social services. In total, 33 community-based organizations working within the area were identified and their role documented. Through distribution of information, education and communication (IEC) materials alone, the project was able to reach 10,670 people using various social mobilization methods, such as convening of sensitization meetings—dubbed 'mosquito days'—mainly spearheaded by primary school pupils. A total of 23 local primary schools participated in creating awareness on malaria prevention and control during the project phase. The collaboration with other departments like fisheries led to stocking of more than 20 fishponds with a total of 18,000 fingerlings in the years 2017 and 2018. Fish ponds provided an opportunity for income generation to the community. In partnership with the county government health department, the project was able to re-train 40 CHVs on IVM and malaria case management in the area. Additionally, 40 fish farmers were re-trained on fish farming as part of income generating activity (IGA) while 10 CBOs made up of 509 members received both eucalyptus and Ocimum kilimandscharicum seedlings that were distributed to four CBOs composed of 152 members. Four primary schools made up of 113 health club members also received eucalyptus seedlings as part of IGA in addition to fish farming. In total, around 20,000 eucalyptus seedlings were distributed to the community as part of IGA initiatives. By the end of 2018, the project was able to reach 25,322 people in the community during its two-year advocacy and social mobilization initiatives.

Conclusion

Through advocacy and social mobilization, the IVM strategy improved inter-sectoral collaboration, enhanced capacity building and community participation. However, more IVM related activities are needed to effectively mobilize available resources and increase community participation in malaria control.

Estimating the Fraction of Severe Malaria among Malaria-Positive Children: Analysis of Household Surveys in 19 Malaria-Endemic Countries in Africa

To date, the only robust estimates of severe malaria cases include children who present to the formal healthcare system. It is a challenge to use these data because of varying age ranges of reporting, different diagnosis techniques, surveillance methods, and healthcare utilization. This analysis examined data from 37 Demographic and Health Surveys and Malaria Indicator Surveys across 19 countries in sub-Saharan Africa collected between 2011 and 2018. The outcome of interest is a proxy indicator for severe malaria, defined as a proportion of children aged 6–59 months with at least one self-reported symptom of severe illness including loss of consciousness, rapid breathing, seizures, or severe anemia (hemoglobin < 5 g/dL) among those who were positive for malaria. The study includes a weighted descriptive, country-level analysis and a multilevel mixed-effects logistic regression model to assess the determinants of severe malaria. Among children positive for malaria across all surveys, 4.5% (95% CI: 4.1–4.8) had at least one sign or symptom of severe malaria, which was significantly associated with age, residence, wealth, and year of survey fieldwork at a P-value less than 0.05. This analysis presents a novel and an alternative approach of estimating the fraction of severe malaria cases among malaria-positive children younger than 5 years in malaria-endemic countries. Estimating severe malaria cases through population-based surveys allows countries to estimate severe malaria across time and to compare with other countries. Having a population-level estimate of severe malaria cases helps further our understanding of the burden and epidemiology of severe malaria.

Factors associated with access and adherence to artemisinin-based combination therapy (ACT) for children under five: a secondary analysis of a national survey in Sierra Leone

BACKGROUND

Access and adherence to artemisinin-based combination therapy (ACT) are key challenges to effective malaria treatment. A secondary analysis of the Sierra Leone malaria Knowledge, Attitudes, and Practices (mKAP) survey was conducted to investigate access and adherence to ACT for the treatment of fever in children under-five.

METHODS

The mKAP was a nationally representative, two-stage cluster-sample survey, conducted in 2012. Thirty primary sampling units per district were randomly selected using probability proportionate to size, based on national census estimates; 14 households were subsequently randomly selected and enrolled per sampling unit. The analysis was restricted to children under-five with fever in the past two weeks. Factors associated with access and adherence were assessed using multivariate logistic regression.

RESULTS

Of 5169 enrolled households, 1456 reported at least one child under-five with fever in the past two weeks. Of the 1641 children from these households, 982 (59.8%) received any treatment for fever and were analysed for access to ACT; 469 (47.6%) received ACT and 466 were analysed for treatment adherence. Only 222 (47.4%) febrile children received ACT and completed 3-day treatment. In an adjusted analysis, factors associated with ACT access included knowledge of ACT (odds ratio [OR] 2.78, 95% CI 2.02-3.80; p < 0.001), knowledge of insecticide-treated nets (ITNs) (OR 1.84, 95% CI 1.29-2.63; p = 0.001), source of care (public health facility vs. other; OR 1.86, 95% CI 1.27-2.72, p = 0.001), geographic region (East vs. West; OR 2.30, 95% CI 1.20-4.44; p = 0.025), and age (24-59 vs. 0-23 months; OR 1.45, 95% CI 1.07-1.96; p = 0.016). The only factor associated with ACT adherence was time to treatment; children treated within 24 h were less likely to adhere (OR 0.55, 95% CI 0.34-0.89; p = 0.015).

CONCLUSIONS

In 2012, access and adherence to ACT remained low in Sierra Leone. Knowledge of ACT and ITNs, and seeking care in the public sector, were most strongly associated with ACT access. National surveys provide important information on anti-malarial access and could be expanded to measure treatment adherence.

Constructing a malaria-related health service readiness index and assessing its association with child malaria mortality: an analysis of the Burkina Faso 2014 SARA data

Background

The Service Availability and Readiness Assessment surveys generate data on the readiness of health facility services. We constructed a readiness index related to malaria services and determined the association between health facility malaria readiness and malaria mortality in children under the age of 5 years in Burkina Faso.

Methods

Data on inpatients visits and malaria-related deaths in under 5-year-old children were extracted from the national Health Management Information System in Burkina Faso. Bayesian geostatistical models with variable selection were fitted to malaria mortality data. The most important facility readiness indicators related to general and malaria-specific services were determined. Multiple correspondence analysis (MCA) was employed to construct a composite facility readiness score based on multiple factorial axes. The analysis was carried out separately for 112 medical centres and 546 peripheral health centres.

Results

Malaria mortality rate in medical centres was 4.8 times higher than that of peripheral health centres (3.5% vs. 0.7%, p < 0.0001). Essential medicines was the domain with the lowest readiness (only 0.1% of medical centres and 0% of peripheral health centres had the whole set of tracer items of essential medicines). Basic equipment readiness was the highest. The composite readiness score explained 30 and 53% of the original set of items for medical centres and peripheral health centres, respectively. Mortality rate ratio (MRR) was by 59% (MRR = 0.41, 95% Bayesian credible interval: 0.19–0.91) lower in the high readiness group of peripheral health centres, compared to the low readiness group. Medical centres readiness was not related to malaria mortality. The geographical distribution of malaria mortality rate indicate that regions with health facilities with high readiness show lower mortality rates.

Conclusion

Performant health services in Burkina Faso are associated with lower malaria mortality rates. Health system readiness should be strengthened in the regions of Sahel, Sud-Ouest and Boucle du Mouhoun. Emphasis should be placed on improving the management of essential medicines and to reducing delays of emergency transportation between the different levels of the health system.

Self-medication practice with antimalarials & the determinants of malaria treatment-seeking behavior among postpartum mothers in a rural community in Nigeria

BACKGROUND

The majority of the population has inappropriate malaria treatment-seeking behavior and little is known about self-medication practice with antimalarials among postpartum mothers.

AIM & OBJECTIVES OF STUDY

The study, therefore, aims to determine the prevalence of self-treatment practice with antimalarials and identify factors that determine inappropriate treatment-seeking practice in this susceptible group.

RESEARCH METHODS

The study is a cross-sectional study that was conducted using a purposive sampling technique. In the study, 150 respondents were administered questionnaires by one-on-one interviews, and results were presented as frequencies and proportions. A chi-square test was done to determine the association between independent categorical variables and the dependent variable.

RESULTS

In the study, 91 (60.7%) of the women claimed they did malaria screening tests in the laboratory/clinic before treatment, while only half of them sought professional care for treatment after the screening test. Additionally, most of the participants claimed they practice self-medication with antimalarials for themselves (64, 42.7%), and their newborn children (34, 22.7%). The experience of adverse effects (χ² = 4.790, df = 1, p = .029) drug prescription by doctors (χ² = 10.26, df = 1, p = .001) and the experience of malaria in the rainy season (χ² = 4.86, df = 2, p = .027) was significantly related to receiving malaria treatment in the clinic/hospital.

CONCLUSION

The study has shown that the practice of self-medication and inappropriate malaria treatment behavior is common in postpartum women in rural settings hence public health intervention that will develop standardized self-treatment guidelines for uncomplicated malaria will be useful in promoting appropriate self-treatment practice in this population. Highlights Self-medication practice with antimalarials among postpartum mothers both for themselves and their newborn child was 42.7% and 22.7% respectively One of the reasons adduced for such practice is that malaria is expensive to treat (37, 24.7%) Artemether/lumefantrine combination was the most commonly used drug for treatment (75.3%), and most of the participants preferred parenteral medication (68%) to oral drugs The experience of adverse effects was significantly related to receiving treatment in the clinic/hospital Of the 60.7% of women who claimed they did malaria screening test, only half of them sought professional care after the test.

Tracking health commodity inventory and notifying stock levels via mobile devices: a mixed methods systematic review

BACKGROUND

Health systems need timely and reliable access to essential medicines and health commodities, but problems with access are common in many settings. Mobile technologies offer potential low-cost solutions to the challenge of drug distribution and commodity availability in primary healthcare settings. However, the evidence on the use of mobile devices to address commodity shortages is sparse, and offers no clear way forward.

OBJECTIVES

Primary objective To assess the effects of strategies for notifying stock levels and digital tracking of healthcare-related commodities and inventory via mobile devices across the primary healthcare system Secondary objectives To describe what mobile device strategies are currently being used to improve reporting and digital tracking of health commodities To identify factors influencing the implementation of mobile device interventions targeted at reducing stockouts of health commodities SEARCH METHODS: We searched CENTRAL, MEDLINE Ovid, Embase Ovid, Global Index Medicus WHO, POPLINE K4Health, and two trials registries in August 2019. We also searched Epistemonikos for related systematic reviews and potentially eligible primary studies. We conducted a grey literature search using mHealthevidence.org, and issued a call for papers through popular digital health communities of practice. Finally, we conducted citation searches of included studies. We searched for studies published after 2000, in any language.

SELECTION CRITERIA

For the primary objective, we included individual and cluster-randomised trials, controlled before-after studies, and interrupted time series studies. For the secondary objectives, we included any study design, which could be quantitative, qualitative, or descriptive, that aimed to describe current strategies for commodity tracking or stock notification via mobile devices; or aimed to explore factors that influenced the implementation of these strategies, including studies of acceptability or feasibility. We included studies of all cadres of healthcare providers, including lay health workers, and others involved in the distribution of health commodities (administrative staff, managerial and supervisory staff, dispensary staff); and all other individuals involved in stock notification, who may be based in a facility or a community setting, and involved with the delivery of primary healthcare services. We included interventions aimed at improving the availability of health commodities using mobile devices in primary healthcare settings. For the primary objective, we included studies that compared health commodity tracking or stock notification via mobile devices with standard practice. For the secondary objectives, we included studies of health commodity tracking and stock notification via mobile device, if we could extract data relevant to our secondary objectives.

DATA COLLECTION AND ANALYSIS

For the primary objective, two authors independently screened all records, extracted data from the included studies, and assessed the risk of bias. For the analyses of the primary objectives, we reported means and proportions where appropriate. We used the GRADE approach to assess the certainty of the evidence, and prepared a 'Summary of findings' table. For the secondary objective, two authors independently screened all records, extracted data from the included studies, and applied a thematic synthesis approach to synthesise the data. We assessed methodological limitation using the Ways of Evaluating Important and Relevant Data (WEIRD) tool. We used the GRADE-CERQual approach to assess our confidence in the evidence, and prepared a 'Summary of qualitative findings' table.

MAIN RESULTS

Primary objective For the primary objective, we included one controlled before-after study conducted in Malawi. We are uncertain of the effect of cStock plus enhanced management, or cStock plus effective product transport on the availability of commodities, quality and timeliness of stock management, and satisfaction and acceptability, because we assessed the evidence as very low-certainty. The study did not report on resource use or unintended consequences. Secondary objective For the secondary objectives, we included 16 studies, using a range of study designs, which described a total of eleven interventions. All studies were conducted in African (Tanzania, Kenya, Malawi, Ghana, Ethiopia, Cameroon, Zambia, Liberia, Uganda, South Africa, and Rwanda) and Asian (Pakistan and India) countries. Most of the interventions aimed to make data about stock levels and potential stockouts visible to managers, who could then take corrective action to address them. We identified several factors that may influence the implementation of stock notification and tracking via mobile device. These include challenges tied to infrastructural issues, such as poor access to electricity or internet, and broader health systems issues, such as drug shortages at the national level which cannot be mitigated by interventions at the primary healthcare level (low confidence). Several factors were identified as important, including strong partnerships with local authorities, telecommunication companies, technical system providers, and non-governmental organizations (very low confidence); availability of stock-level data at all levels of the health system (low confidence); the role of supportive supervision and responsive management (moderate confidence); familiarity and training of health workers in the use of the digital devices (moderate confidence); availability of technical programming expertise for the initial development and ongoing maintenance of the digital systems (low confidence); incentives, such as phone credit for personal use, to support regular use of the system (low confidence); easy-to-use systems built with user participation (moderate confidence); use of basic or personal mobile phones to support easier adoption (low confidence); consideration for software features, such as two-way communication (low confidence); and data availability in an easy-to-use format, such as an interactive dashboard (moderate confidence).

AUTHORS' CONCLUSIONS

We need more, well-designed, controlled studies comparing stock notification and commodity management via mobile devices with paper-based commodity management systems. Further studies are needed to understand the factors that may influence the implementation of such interventions, and how implementation considerations differ by variations in the intervention.

Assessment of Malaria Predisposing Factors among Crop Production Farmers Attending the Ndop District Hospital, Northwest Region of Cameroon

The widespread impacts of malaria in the tropical regions of the developing world are not only on healthcare issues but also an agricultural output. Malaria causes manpower loss when it strikes farmers at critical planting, weeding, and harvesting times. Given the above, the expected outcome to malaria prevention programs in farming communities remains a far cry, especially where the predisposing factors are not properly identified and long-lasting solutions proffered. Consequently, this study was designed to assess the malaria predisposing factors among the crop production farmers attending the Ndop District Hospital. The microscopy method was used to determine the presence of malaria parasitaemia. The following categorical variables were considered predisposing factors: Sex, history on malaria illness/treatment, use of long-lasting insecticide nets (LLINs) and knowledge on malaria transmission/prevention. A four-point Likert-type rating scale was adopted for the scoring of the responses given on the predisposing factors, while Fisher's exact test was used to assess the associations between malaria and each of the predisposing factors. The prevalence of malaria parasitaemia among the crop production farmers was 20% (143/715). The predisposing factors tested were found to be significantly associated to the occurrence of malaria among the crop production farmers. Therefore, the combination of improved existing and innovative malaria control strategies may possibly ensure sustained malaria decrease among the farmers in the Ndop Health District.

Proactive community case management in Senegal 2014-2016: a case study in maximizing the impact of community case management of malaria

The Senegal National Malaria Control Programme (NMCP) introduced home-based malaria management for all ages, with diagnosis by rapid diagnostic test (RDT) and treatment with artemisinin-based combination therapy (ACT) in 2008, expanding to over 2000 villages nationwide by 2014. With prise en charge à domicile (PECADOM), community health workers (CHWs) were available for community members to seek care, but did not actively visit households to find cases. A trial of a proactive model (PECADOM Plus), in which CHWs visited all households in their village weekly during transmission season to identify fever cases and offer case management, in addition to availability during the week for home-based management, found that CHWs detected and treated more cases in intervention villages, while the number of cases detected weekly decreased over the transmission season. The NMCP scaled PECADOM Plus to three districts in 2014 (132 villages), to a total of six districts in 2015 (246 villages), and to a total of 16 districts in 2016 (708 villages). A narrative case study with programmatic results is presented. During active sweeps over approximately 20 weeks, CHWs tested a mean of 77 patients per CHW in 2014, 89 patients per CHW in 2015, and 90 patients per CHW in 2016, and diagnosed a mean of 61, 61 and 43 patients with malaria per CHW in 2014, 2015 and 2016, respectively. The number of patients who sought care between sweeps increased, with a 104% increase in the number of RDTs performed and a 77% increase in the number of positive tests and patients treated with ACT during passive case detection. While the number of CHWs increased 7%, the number of patients receiving an RDT increased by 307% and the number of malaria cases detected and treated by CHWs increased 274%, from the year prior to PECADOM Plus introduction to its first year of implementation. Based on these results, approximately 700 additional CHWs in 24 new districts were added in 2017. This case study describes the process, results and lessons learned from Senegal’s implementation of PECADOM Plus, as well as guidance for other programmes considering introduction of this innovative strategy.

Malaria Case Fatality Rate among Children under Five in Burkina Faso: An Assessment of the Spatiotemporal Trends Following the Implementation of Control Programs

Reducing the 2015 level of malaria mortality by 90% by 2030 is a goal set by the World Health Organization (WHO). In Burkina Faso, several malaria control programs proven to be effective were implemented over the last decade. In parallel, the progressive strengthening of the health surveillance system is generating valuable data, which represents a great opportunity for analyzing the trends in malaria burden and assessing the effect of these control programs. Complementary programs were rolled out at different time points and paces, and the present work aims at investigating both the spatial and temporal pattern of malaria case fatality rate (mCFR) by considering the effect of combining specific and unspecific malaria control programs. To this end, data on severe malaria cases and malaria deaths, aggregated at health district level between January 2013 and December 2018, were extracted from the national health data repository (ENDOS-BF). A Bayesian spatiotemporal zero-inflated Poisson model was fitted to quantify the strength of the association of malaria control programs with monthly mCFR trends at health district level. The model was adjusted for contextual variables. We found that monthly mCFR decreased from 2.0 (95% IC 1.9-2.1%) to 0.9 (95% IC 0.8-1.0%) deaths for 100 severe malaria cases in 2013 and 2018, respectively. Health districts with high mCFR were identified in the northern, northwestern and southwestern parts of the country. The availability of malaria rapid diagnosis tests (IRR: 0.54; CrI: 0.47, 0.62) and treatment (IRR: 0.50; CrI: 0.41, 0.61) were significantly associated with a reduction in the mCFR. The risk of dying from malaria was lower in the period after the free healthcare policy compared with the period before (IRR: 0.47; CrI: 0.38, 0.58). Our findings highlighted locations that are most in need of targeted interventions and the necessity to sustain and strengthen the launched health programs to further reduce the malaria deaths in Burkina Faso.

Socio-economic inequality and inequity in use of health care services in Kenya: evidence from the fourth Kenya household health expenditure and utilization survey

Background

Kenya is experiencing persistently high levels of inequity in health and access to care services. In 2018, decades of sustained policy efforts to promote equitable, affordable and quality health services have culminated in the launch of a universal health coverage scheme, initially piloted in four Kenyan counties and planned for national rollout by 2022. Our study aims to contribute to monitoring and evaluation efforts alongside policy implementation, by establishing a detailed, baseline assessment of socio-economic inequality and inequity in health care utilization in Kenya shortly before the policy launch.

Methods

We use concentration curves and corrected concentration indexes to measure socio-economic inequality in care use and the horizontal inequity index as a measure of inequity in care utilization for three types of care services: outpatient care, inpatient care and preventive and promotive care. Further insights into the individual and household level characteristics that determine observed inequality are derived through decomposition analysis.

Results

We find significant inequality and inequity in the use of all types of care services favouring richer population groups, with particularly pronounced levels for preventive and inpatient care services. These are driven primarily by differences in living standards and educational achievement, while the region of residence is a key driver for inequality in preventive care use only. Pro-rich inequalities are particularly pronounced for care provided in privately owned facilities, while public providers serve a much larger share of individuals from lower socio-economic groups.

Conclusions

Through its focus on increasing affordability of care for all Kenyans, the newly launched universal health coverage scheme represents a crucial step towards reducing disparities in health care utilization. However in order to achieve equity in health and access to care such efforts must be paralleled by multi-sectoral approaches to address all key drivers of inequity: persistent poverty, disparities in living standards and educational achievement, as well as regional differences in availability and accessibility of care.

Challenges in Treatment for Fever among School-Age Children and Adults in Malawi

Prompt and effective treatment is key to malaria control and prevention, as it reduces disease morbidity and mortality and minimizes the number of transmission reservoirs. Transmission reduction may be particularly important among school-age children (SAC, 5-15 years old), who have the highest prevalence of Plasmodium falciparum infection in southern Malawi. We hypothesized that one factor contributing to this difference in prevalence is that SAC are less likely to seek appropriate treatment for fever than children younger than 5 years. In this study, we assessed treatment-seeking behaviors of people of all ages between 2012 and 2014 in Malawi. During each of the five cross-sectional surveys, all members of ∼900 households reported on fever and treatment-seeking in the previous 2 weeks. Multilevel logistic regression was used to analyze predictors of whether febrile people sought treatment and whether they did so at formal (government/private clinics) or informal sources (primarily shops). Twenty-two percent of participants (3,579/16,621) reported fever, and 2,715 of those (75.9%) sought treatment. Seeking treatment exclusively from local shops remains a common practice, although use of recommended diagnostic testing and antimalarial drugs was infrequently reported there. Although SAC were not significantly less likely than children aged < 5 years to seek treatment, SAC and adults (age ≥ 16 years) were significantly less likely to use formal sources. Our results indicate that encouraging treatment at government/private clinics and increasing retail access to appropriate antimalarial testing and treatment, especially among SAC, could help remedy inadequate treatment of symptomatic disease and potentially reduce Plasmodium transmission in Malawi.

Proximity to a community health worker is associated with utilization of malaria treatment services in the community among under-five children: a cross-sectional study in rural Uganda

BACKGROUND

In rural areas of sub-Saharan Africa, health facilities are difficult to access for prompt treatment of malaria. Community health workers (CHWs) have been trained and equipped to treat malaria. Utilization of their service has not been adequately evaluated. The aim of this study was to determine the level of utilization of CHWs, and whether distance and other factors influence the utilization.

METHODS

The authors conducted a cross-sectional study among households with a child below 5 y of age and interviewed caregivers in Sheema district, rural western Uganda. Logistic regression was used to calculate adjusted ORs (aOR) for factors associated with use of CHW services.

RESULTS

Among 547 households, 64% (338/528) reported using CHWs as the first point of consultation for their febrile children. Factors associated with the use of CHWs services were lower asset index (aOR=1.9, p=0.02), mother being the decision maker for site of first consultation (aOR=1.9, p=0.01), distance to nearest CHW of <3 km (aOR=2.1, p=0.03) compared to >3 km, and trust for CHWs services (aOR=7.8, p<0.001).

CONCLUSION

Proximal location to a CHW is associated with use of CHW services. Programs should ensure that CHW are well located to enable easy access.

The effect of subsidized malaria treatment among under-five children in the Buea Health District, Cameroon

Introduction

Access to free diagnoses and treatments has been shown to be a major determinant in malaria control. The Cameroon government launched in 2011 and 2014 the exemption of the under-fives' simple and severe malaria treatment policy to increase access to health care and reduce inequality, so as to reduce the mortality related to malaria among the under-fives. This study assessed the effect of providing free malaria treatment in the Buea health district.

Methods

This retrospective and cross sectional study was carried out in the Buea health district. Aggregated monthly data from (2008-2010) before and (2012-2014) after the implementation of free malaria treatment was compared, to assess the attributable outcomes of free treatment. A semi-structure questionnaire was also used to assess barriers faced in providing free malaria treatment services by health care workers. Data was collected using a semi-structure questionnaire and a data review summary sheet. The data was analysed using Epi-Info 7, Excel and SPSS (Statistical Package for the Social Sciences) version 20.0 for Windows. All statistical tests were performed at 95% confidence interval (significance level of 0.05).

Results

Increase utilisation of health care; as general and malaria related consultations (by 5.7% (p=0.001) witnessed an increase after the implementation of free malaria treatment services. Severe malaria hospitalisation also increased, indicating that most caregivers used the health facility when complications had already set in, which could have led to no significant reduction in mortality due to malaria among under-five children (4.4%, p=0.533).

Conclusion

Utilisation of health care increased; as consultation and morbidity rate increased after the implementation of free malaria treatment services. Communication strategy should therefore be strengthened so as to better disseminate information, so as to enhance the effectiveness of the program. There is the need to make a large-scale study to assess the impact of subsidized malaria treatment.

Examination of malaria service utilization and service provision: an analysis of DHS and SPA data from Malawi, Senegal, and Tanzania

Background

Ensuring universal access to malaria diagnosis and treatment is a key component of Pillar 1 of the World Health Organization Global Technical Strategy for Malaria 2016–2030. To achieve this goal it is essential to know the types of facilities where the population seeks care as well as the malaria service readiness of these facilities in endemic countries.

Methods

To investigate the utilization and provision of malaria services, data on the sources of advice or treatment in children under 5 years with fever from the household-based Demographic and Health Surveys (DHS) and on the components of malaria service readiness from the facility-based Service Provision Assessment (SPA) surveys were examined in Malawi, Senegal and Tanzania. Facilities categorized as malaria-service ready were those with: (1) personnel trained in either malaria rapid diagnostic testing (RDT), microscopy or case management/treatment of malaria in children; (2) national guidelines for the diagnosis and treatment of malaria; (3) diagnostic capacity (available RDT tests or microscopy equipment as well as staff trained in its use); and, (4) unexpired artemisinin-based combination therapy (ACT) available on the day of the survey.

Results

In all three countries primary-level facilities (health centre/health post/health clinic) were the type of facility most used for care of febrile children. However, only 69% of these facilities in Senegal, 32% in Malawi and 19% in Tanzania were classified as malaria-service ready. Of the four components of malaria-service readiness in the facilities most frequented by febrile children, diagnostic capacity was the weakest area in all three countries, followed by trained personnel. All three countries performed well in the availability of ACT.

Conclusions

This analysis highlights the need to improve the malaria-service readiness of facilities in all three countries. More effort should be focused on facilities that are commonly used for care of fever, especially in the areas of malaria diagnostic capacity and provider training. It is essential for policymakers to consider the malaria-service readiness of primary healthcare facilities when allocating resources. This is particularly important in limited-resource settings to ensure that the facilities most visited for care are properly equipped to provide diagnosis and treatment for malaria.

Assessing the causes of under-five mortality and proportion associated with pneumococcal diseases in Cameroon. A case-finding retrospective observational study: 2006-2012

BACKGROUND

Vital registration data outlining causes of deaths (CoD) are important for a sustainable health system, targeted interventions and other relevant policies. There is data paucity on vital registration systems in developing countries. We assessed the leading causes and proportions of under-five deaths, and particularly those related to pneumococcal infections in Yaoundé, Cameroon, using hospital registration data.

METHODS

A retrospective case-finding observational study design was used to access and identify data on 817 death cases in children under-five years of age recorded in health facilities in Yaoundé, within the period January 1, 2006 and December 31, 2012. Patients' files were randomly selected and needed information including demographic data, date of admission, clinical and laboratory diagnosis, principal and/or underlying causes of death were abstracted into structured case report forms. The International Classification of Diseases and Clinical Modifications 10th revision (ICD-10-CM) codes (ICD10Data.com 2017 edition) were used to classify the different CoD, retrospectively. Ascertainment of CoD was based on medical report and estimates were done using the Kaplan-Meier procedure and descriptive statistics.

RESULTS

Of the 817 death records assessed, malaria was the leading CoD and was responsible for 17.5% of cases. Meningitis was the second largest CoD with 11.0%; followed by sepsis (10.0%), Streptococcus pneumoniae infections (8.3%), malnutrition (8.3%), gastro-enteritis / diarrhoea (6.2%), anaemia (6.1%) and HIV (3.5%), respectively.

CONCLUSION

The main CoD in this population are either treatable or vaccine-preventable; a trend consistent with previous reports across developing countries. Besides, the health effects from non-communicable infections should not be neglected. Therefore, scaling-up measures to reduce causes of under-five deaths will demand sustainable efforts to enhance both treatment and disease prevention strategies, to avoid a decline in the progress towards reducing under-five deaths by 2/3 from the 1990 baseline.

Effectiveness of antimalarial interventions in Nigeria: Evidence from facility-level longitudinal data

OBJECTIVE

To evaluate the effectiveness of a program of antimalarial interventions implemented in 2010-2013 in Niger State, Nigeria.

DATA SOURCES

Utilization reports from 99 intervention and 51 non-intervention health facilities from the Niger State Malaria Elimination Program, supplemented by data on facility-level characteristics from the Niger State Primary Health Care Development Agency and Local Government Malaria Control units.

STUDY DESIGN

Estimated with mixed-effects negative binomial modeling, a difference-in-differences method was used to quantify the impact of the program on the number of febrile illness cases and confirmed malaria cases. Potential confounding factors, non-stationarity, seasonality, and autocorrelation were explicitly accounted for.

DATA EXTRACTION METHODS

Data were retrieved from hard copies of utilization reports and manually inputted to create a panel of 5550 facility-month observations.

PRINCIPAL FINDINGS

The program was implemented in two phases. The first phase (August 2010-June 2012) involved the provision of free artemisinin-based combination therapies, long-lasting insecticidal nets, and intermittent preventive treatments. In the second phase (July 2012-March 2013), the program introduced an additional intervention: free parasite-based rapid diagnostic tests. Compared to the pre-intervention period, the average number of monthly febrile illness and malaria cases increased by 20.876 (P < 0.01) and 22.835 (P < 0.01) in the first phase, and by 19.007 (P < 0.05) and 19.681 (P < 0.05) in the second phase, respectively. The results are consistent across different evaluation methods.

CONCLUSIONS

This study suggests that user-fee removal leads to increased utilization of antimalarial services. It motivates future studies to cautiously select their investigative methods.

Challenges for the diagnosis and treatment of malaria in low transmission settings in San Lorenzo, Esmeraldas, Ecuador

BACKGROUND

Ecuador is on the verge of eliminating malaria according to the World Health Organization criteria. Nevertheless, active transmission foci still persist in the country, and these represent an important challenge for achieving the objectives set out. Diagnosis and treatment are a mainstay in the control and elimination of this disease. This study aimed to explore the barriers hindering the implementation of malaria diagnosis and treatment strategies in a focus of active transmission in the San Lorenzo canton, Ecuador.

METHODS

Using a convergent mixed methods design during 2017, the researchers assessed the physical and human resources of the services network at the primary level of care along with the quality assurance activities, patient access to healthcare services and perceptions regarding the care provided to patients with malaria.

RESULTS

The programme's administrative transition from the National Service of Vector-borne Diseases to the Ministry of Public Health is perceived from the interviewed participants to have weakened the diagnosis network established in recent years. A mean of 6.4 ± 0.88 months was found for anti-malarial medication shortage at the primary level of care. Likewise, there was high healthcare staff turnover (permanence, Me = 7 months; IQR = 5-16) and a deficit of general knowledge on the disease among the entirety of healthcare staff, as only 29% of physicians were aware of the correct first-line treatment for malaria by Plasmodium falciparum and Plasmodium vivax. It was evidenced that 95.7% of patients were hospitalized to receive anti-malarial treatment. Both patients and healthcare staff considered the area to be difficult to reach due to its geography and the presence of groups outside the law. They also identified the lack of personnel and microscopy posts in this border area as the main barrier.

CONCLUSION

The network of diagnostic services for malaria is weak in San Lorenzo, and socio-economic, political and historical factors hinder the implementation of the universal malaria elimination strategy based on diagnosis and treatment.

Community-informed research on malaria in pregnancy in Monrovia, Liberia: a grounded theory study

BACKGROUND

Liberia is a West African country that needs substantial investment to strengthen its National Malaria Control Programme (NMCP), which was disrupted during the 2014-2016 Ebola epidemic. As elsewhere, Liberian pregnant women are especially vulnerable to malaria. Understanding prevention and treatment-seeking behaviours among the population is crucial to strategize context-specific and women-centred actions, including locally-led malaria research, to improve women's demand, access and use of NMCP strategies against malaria in pregnancy.

METHODS

In 2016, after the Ebola crisis, a qualitative inquiry was conducted in Monrovia to explore populations' insights on the aetiology, prevention and therapeutics of malaria, as well as the community and health workers' perceptions on the utility of malaria research for pregnant women. In-depth interviews and focus group discussions were conducted among pregnant women, traditional community representatives and hospital staff (n = 38), using a feminist interpretation of grounded theory.

RESULTS

The narratives indicate that some Liberians believed in elements other than mosquito bites as causes of malaria; many had a low malaria risk perception and disliked current effective prevention methods, such as insecticide-treated nets; and some would resort to traditional medicine and spiritual care to cure malaria. Access to clinic-based malaria care for pregnant women was reportedly hindered by lack of financial means, by unofficial user fees requested by healthcare workers, and by male partners' preference for traditional medicine. The participants suggested that malaria research in Liberia could help to design evidence-based education to change current malaria prevention, diagnostic and treatment-seeking attitudes, and to develop more acceptable prevention technologies.

CONCLUSION

Poverty, insufficient education on malaria, corruption, and poor trust in healthcare establishment are structural factors that may play a greater role than local traditional beliefs in deterring Liberians from seeking, accessing and using government-endorsed malaria control strategies. To increase access to and uptake of preventive and biomedical care by pregnant women, future malaria research must be informed by people's expressed needs and constructed meanings and values on health, ill health and healthcare.

Improving prompt access to malaria diagnostics and treatment in rural remote areas using financial benefit for community health workers in Kilosa district, Tanzania

PURPOSE

Improving access to malaria treatment in rural remote areas remains a major challenge facing innovative strategies, such as Accredited Drug Dispensing Outlets (ADDOs) and Community Health Workers (CHWs) programs in Tanzania. This study tested the effectiveness of a financial benefit approach to motivate CHWs to improve prompt access to malaria treatment.

PATIENTS AND METHODS

We applied a quasi-experimental study design in rural-remote areas in Kilosa district, Tanzania. Febrile children in selected intervention areas were provided access to malaria diagnostic and treatment at a minimal fee to CHWs and compared with non-intervention areas. We measured impact using difference in differences (DID) analysis.

RESULTS

At baseline, 870 children <5 years of age were recruited and 1,127 in post-intervention. The DID in prompt access to malaria diagnostics and treatment was 28.0% in favor of intervention. A net pre and post decrease (DID=24.1%) in seeking care from public facilities was observed, signifying decrease in workload. Incidentally, knowledge on malaria treatment increased in intervention area (DID 11%-21%).

CONCLUSION

Using the financial benefit approach, CHWs were able to significantly improve prompt access to malaria diagnostics and treatment in rural remote areas. Scaling up of the strategy might speed up the pace toward achieving national target of accurate diagnosis and appropriate treatment by 80% in 2020.

Malaria vector abundance is associated with house structures in Baringo County, Kenya

Malaria, a major cause of morbidity and mortality, is the most prevalent vector borne disease in Baringo County; a region which has varied house designs in arid and semi-arid areas. This study investigated the association between house structures and indoor-malaria vector abundance in Baringo County. The density of malaria vectors in houses with open eaves was higher than that for houses with closed eaves. Grass thatched roof houses had higher density of malaria vectors than corrugated iron sheet roofs. Similarly, mud walled houses had higher vector density than other wall types. Houses in the riverine zone were significantly associated with malaria vector abundance (p<0.000) possibly due to more varied house structures. In Kamnarok village within riverine zone, a house made of grass thatched roof and mud wall but raised on stilts with domestic animals (sheep/goats) kept at the lower level had lower mosquito density (5.8 per collection) than ordinary houses made of same materials but at ground level (30.5 mosquitoes per collection), suggestive of a change in behavior of mosquito feeding and resting. House modifications such as screening of eaves, improvement of construction material and building stilted houses can be incorporated in the integrated vector management (IVM) strategy to complement insecticide treated bed nets and indoor residual spray to reduce indoor malaria vector density.

Community-based training of medical students is associated with malaria prevention and treatment seeking behaviour for children under 5 years in Uganda: a study of MESAU-MEPI COBERS in Uganda

BACKGROUND

Four university medical training institutions in Uganda have trained students at off-site health facilities under community-based education and Research Service (COBERS) programme for over 5 years. One of the major components of COBERS placement is for the students to provide health education in the communities about malaria as a major public health disease in Uganda. This study seeks to assess if targeted community-based medical education programme is associated with better prevention and treatment seeking behaviours in the management of malaria, a leading cause of morbidity and mortality of children under five in Uganda.

METHODS

A cross-sectional survey was done to compare communities around health facilities where medical students were placed at COBERS sites with communities around similar health facilities where medical students were not placed (non-COBERS sites). We randomly selected two villages near each health facility and consecutively selected 10 households per village for interviews using nearest-neighbour method. We used a structured questionnaire to interview household heads on malaria prevention and treatment seeking behaviour for children under 5 years. We performed univariate analysis to determine site and demographic characteristics and performed a multivariate logistic regression to assess association between dependant and independent variables.

RESULTS

Five hundred twenty-three (66.8%) of the children under 5 years in COBERS communities slept under Insecticide Treated Nets (ITNs) the night before survey compared with 1451 (57.8%) in non-COBERS communities (AOR = 0.66, p = 0.017). 100 (60.0%) of children under 5 years in COBERS communities sought care for fever within 24 h of onset compared with 268 (47.0%) in non-COBERS communities (AOR = 0.71, P = 0.009).

CONCLUSION

The presence of COBERS in communities is associated with improved malaria prevention and treatment-seeking behaviour for parents of children under 5 years. Further study needs to be done to determine the long-term impact of COBERS training program on malaria control and prevention in Uganda, along with other effects of COBERS.

Factors associated with treatment-seeking for malaria in urban poor communities in Accra, Ghana

BACKGROUND

In Ghana, about 3.5 million cases of malaria are recorded each year. Urban poor residents particularly have a higher risk of malaria mainly due to poor housing, low socio-economic status and poor sanitation. Alternative treatment for malaria (mainly African traditional/herbal and/or self-medication) is further compounding efforts to control the incidence of malaria in urban poor communities. This study assesses factors associated with seeking alternative treatment as the first response to malaria, relative to orthodox treatment in three urban poor communities in Accra, Ghana.

METHODS

This cross-sectional study was conducted in three urban poor localities in Accra, Ghana among individuals in their reproductive ages (15-59 years for men and 15-49 years for women). The analytic sample for the study was 707. A multinomial regression model was used to assess individual, interpersonal and structural level factors associated with treatment-seeking for malaria.

RESULTS

Overall, 31% of the respondents sought orthodox treatment, 8% sought traditional/herbal treatment and 61% self-medicated as the first response to malaria. At the bivariate level, more males than females used traditional/herbal treatment and self-medicated for malaria. The results of the regression analysis showed that current health insurance status, perceived relative economic standing, level of social support, and locality of residence were associated with seeking alternative treatment for malaria relative to orthodox treatment.

CONCLUSIONS

The findings show that many urban poor residents in Accra self-medicate as the first response to malaria. Additionally, individuals who were not enrolled in a health insurance scheme, those who perceived they had a low economic standing, those with a high level of social support, and locality of residence were significantly associated with the use of alternative treatment for malaria. Multi-level strategies should be employed to address the use of alternative forms of treatment for malaria within the context of urban poverty.

Low use of artemisinin-based combination therapy for febrile children under five and barriers to correct fever management in Benin: a decade after WHO recommendation

Background

Artemisinin-based combination therapy (ACT), used to treat uncomplicated malaria cases, is one of the main strategies of malaria control and elimination. One of the main objectives of the Benin National Malaria Control Program’s (NMCP) strategic plan is to ensure that at least 80% of uncomplicated malaria is treated with ACT within 24 h. Therefore, it was of great interest to measure whether the country case management of fever amongst children under five, adhered to the NMCP’s strategic plan and look into the barriers to the use of ACT.

Methods

A cross-sectional survey based on a cluster and multi-stage sampling was conducted in two rural health districts in Benin. We recruited 768 and 594 children under five years were included in the northern and in the southern respectively. Data was collected on the general use of ACT and on the correct use of ACT that adheres to the NMCP’s strategy, as well as the barriers that prevent the proper management of fever amongst children. To assess the certain predictors of ACT usage, logistic regression was used, while taking into account the cluster random effect.

Results

Among febrile children aged 6 to 59 months, 20.7% in the south and 33.9% in north received ACT. The correct use of ACT, was very low, 5.8% and in southern and 8.6% northern areas. Caregivers who received information on ACT were 3.13 time more likely in the south and 2.98 time more likely in the north to give ACT to their feverish child, PPR = 3.13[1.72–4.15] and PPR = 2.98 [2.72–3.11] respectively. Chloroquine and quinine, other malaria treatments not recommended by NMCP, were still being used in both areas: 12.3 and 3.3% in the south and 11.4 and 3.0% in the north.

Conclusion

In Benin, the use and the correct use of ACT for febrile children remains low. The study also showed that having received information about the use of ACT is positively associated with the use of ACT. This point highlights the fact that efforts may not have been sufficiently integrated with social communication, which should be based on the behavioural determinants of populations.

Care-seeking patterns among families that experienced under-five child mortality in rural Rwanda

Background

Over half of under-five deaths occur in sub-Saharan Africa and appropriate, timely, quality care is critical for saving children’s lives. This study describes the context surrounding children’s deaths from the time the illness was first noticed, through the care-seeking patterns leading up to the child’s death, and identifies factors associated with care-seeking for these children in rural Rwanda.

Methods

Secondary analysis of a verbal and social autopsy study of caregivers who reported the death of a child between March 2013 to February 2014 that occurred after discharge from the child’s birth facility in southern Kayonza and Kirehe districts in Rwanda. Bivariate analyses using Fisher’s exact tests were conducted to identify child, caregiver, and household factors associated with care-seeking from the formal health system (i.e., community health worker or health facility). Factors significant at α = 0.10 significance level were considered for backwards stepwise multivariate logistic regression, stopping when remaining factors were significantly associated with care-seeking at α = 0.05 significance level.

Results

Among the 516 eligible deaths among children under-five, 22.7% (n = 117) did not seek care from the health system. For those who did, the most common first point of contact was community health workers (45.8%). In multivariate logistic regression, higher maternal education (OR = 3.36, 95% CI: 1.89, 5.98), having diarrhea (OR = 4.21, 95%CI: 1.95, 9.07) or fever (OR = 2.03, 95%CI: 1.11, 3.72), full household insurance coverage (3.48, 95%CI: 1.79, 6.76), and longer duration of illness (OR = 22.19, 95%CI: 8.88, 55.48) were significantly associated with formal care-seeking.

Conclusion

Interventions such as community health workers and insurance promote access to care, however a gap remains as many children had no contact with the health system prior to death and those who sought formal care still died. Further efforts are needed to respond to urgent cases in communities and further understand remaining barriers to accessing appropriate, quality care.

"We were being treated like the Queen": understanding trial factors influencing high paediatric malaria treatment adherence in western Kenya

BACKGROUND

Adherence to anti-malarial medication is highly variable but frequently suboptimal. Numerous interventions with a variety of methodological approaches have been implemented to address the problem. A recently conducted, randomized, controlled trial in western Kenya evaluated the effects of short message service (SMS) reminders on paediatric adherence to artemether-lumefantrine (AL) and found over 97% adherence rates in both intervention and control arms. The current study was undertaken to explore participants' experiences in the trial and identify the factors contributing to the high adherence rates.

METHODS

In July 2016, 5 months after the trial completion, focus group discussions (FGDs) were undertaken with caregivers of children who had been treated in the intervention (n = 2) or control (n = 2) arms and who, post-trial, had received malaria treatment from the same facilities. The FGDs explored similarities and differences in perceptions and experiences of the care they received during and after the trial.

RESULTS

Intervention-arm participants reported that SMS messages were effective dosing reminders. Participants from both arms reported that trial instructions to keep empty AL packs for verification during a home visit by a health worker affected their dosing and adherence practices. Differences between trial and post-trial treatment experiences included: administration of the first AL dose by health workers with demonstration of dispersible tablets dilution; advice on what to do if a child vomited; clear instructions on timing of dosing with efforts made to ensure understanding; and, information that dose completion was necessary with explanation provided. Participants reported that after the trial AL was not available at facilities, constraining their ability to adhere to recommended malaria treatment. They emphasized receiving respectful and personal treatment from trial health workers contributing to perceptions of high quality care and enhanced readiness to adhere to dosing instructions.

CONCLUSIONS

This study highlights the complex range of factors that influence AL adherence. The results suggest that in addition to standardized definitions and measurement of adherence, and the influence of enrolment procedures, AL adherence trials need to take account of how intervention impact can be influenced by differences in the quality of care received under trial and routine conditions.

Anemia was an Uncommon Complication of Severe Malaria in a High-Transmission Rural Area of Western Uganda

The clinical epidemiology of severe malaria among patients presenting to peripheral health centers has not been well described. We conducted a prospective, observational cohort study to describe the epidemiology and clinical manifestations of severe malaria in a highland area of declining transmission intensity in Western Uganda. Individuals presenting with a history of fever were screened with a malaria rapid diagnostic test (RDT). We prepared blood smears and conducted clinical and laboratory testing for those with a positive RDT. We defined severe malaria in accordance with World Health Organization guidelines for research and epidemiological studies. A total of 6,641 individuals underwent testing for malaria. Ninety-six of 1,462 (6.6%) participants with confirmed parasitemia satisfied the criteria for severe malaria. The incidence of severe malaria peaked between 2 and 3 years of age (incidence rate ratio = 17.1, 95% confidence interval = 8.4-34.9, P < 0.001) and then declined steadily until age 10. However, we also found a second peak among those ≥ 50 years of age. Severe anemia was uncommon, detected in only 5.3% of cases. Instead, shock (22.2%) and lactic acidosis (19.4%) were most frequently encountered. Our results suggest that the clinical characteristics of severe malaria presenting to rural, peripheral health centers may be different than previously observed in referral centers. These findings merit further investigation into the optimal methods for identification and management of severe malaria in rural health centers in the region.
