RESUMO

BACKGROUND: Soil-transmitted helminth infections (STH) are associated with substantial morbidity in low-and-middle-income countries, accounting for 2.7 million disability-adjusted life years annually. Current World Health Organization guidelines recommend controlling STH-associated morbidity through periodic deworming of at-risk populations, including children and women of reproductive age (15-49 years). However, there is increasing interest in community-wide mass drug administration (cMDA) which includes deworming adults who serve as infection reservoirs as a method to improve coverage and possibly to interrupt STH transmission. We investigated determinants of cMDA coverage by comparing high-coverage clusters (HCCs) and low-coverage clusters (LCCs) receiving STH cMDA in three countries. METHODS: A convergent mixed-methods design was used to analyze data from HCCs and LCCs in DeWorm3 trial sites in Benin, India, and Malawi following three rounds of cMDA. Qualitative data were collected via 48 community-level focus group discussions. Quantitative data were collected via routine activities nested within the DeWorm3 trial, including annual censuses and coverage surveys. The Consolidated Framework for Implementation Research (CFIR) guided coding, theme development and a rating process to determine the influence of each CFIR construct on cMDA coverage. RESULTS: Of 23 CFIR constructs evaluated, we identified 11 constructs that differentiated between HCCs and LCCs, indicating they are potential drivers of coverage. Determinants differentiating HCC and LCC include participant experiences with previous community-wide programs, communities' perceptions of directly observed therapy (DOT), perceptions about the treatment uptake behaviors of neighbors, and women's agency to make household-level treatment decisions. CONCLUSION: The convergent mixed-methods study identified barriers and facilitators that may be useful to NTD programs to improve cMDA implementation for STH, increase treatment coverage, and contribute to the successful control or elimination of STH. TRIAL REGISTRATION: The parent trial was registered at clinicaltrials.gov (NCT03014167).

RESUMO

OBJECTIVE: Across Africa, the impact of COVID-19 continues to be acutely felt. This includes Malawi, where a key component of health service delivery to mitigate against COVID-19 are the primary healthcare facilities, strategically placed throughout districts to offer primary and maternal healthcare. These facilities have limited infrastructure and capacity but are the most accessible and play a crucial role in responding to the COVID-19 pandemic. This study assessed health facility preparedness for COVID-19 and the impact of the pandemic on health service delivery and frontline workers. SETTING: Primary and maternal healthcare in Blantyre District, Malawi. PARTICIPANTS: We conducted regular visits to 31 healthcare facilities and a series of telephone-based qualitative interviews with frontline workers (n=81 with 38 participants) between August 2020 and May 2021. RESULTS: Despite significant financial and infrastructural constraints, health centres continued to remain open. The majority of frontline health workers received training and access to preventative COVID-19 materials. Nevertheless, we found disruptions to key services and a reduction in clients attending facilities. Key barriers to implementing COVID-19 prevention measures included periodic shortages of resources (soap, hand sanitiser, water, masks and staff). Frontline workers reported challenges in managing physical distancing and in handling suspected COVID-19 cases. We found discrepancies between reported behaviour and practice, particularly with consistent use of masks, despite being provided. Frontline workers felt COVID-19 had negatively impacted their lives. They experienced fatigue and stress due to heavy workloads, stigma in the community and worries about becoming infected with and transmitting COVID-19. CONCLUSION: Resource (human and material) inadequacy shaped the health facility capacity for support and response to COVID-19, and frontline workers may require psychosocial support to manage the impacts of the COVID-19 pandemic.

RESUMO

BACKGROUND: Declining malaria prevalence and pressure on external funding have increased the need for efficiency in malaria control in sub-Saharan Africa (SSA). Modelled Plasmodium falciparum parasite rate (PfPR) maps are increasingly becoming available and provide information on the epidemiological situation of countries. However, how these maps are understood or used for national malaria planning is rarely explored. In this study, the practices and perceptions of national decision-makers on the utility of malaria risk maps, showing prevalence of parasitaemia or incidence of illness, was investigated. METHODS: A document review of recent National Malaria Strategic Plans was combined with 64 in-depth interviews with stakeholders in Kenya, Malawi and the Democratic Republic of Congo (DRC). The document review focused on the type of epidemiological maps included and their use in prioritising and targeting interventions. Interviews (14 Kenya, 17 Malawi, 27 DRC, 6 global level) explored drivers of stakeholder perceptions of the utility, value and limitations of malaria risk maps. RESULTS: Three different types of maps were used to show malaria epidemiological strata: malaria prevalence using a PfPR modelled map (Kenya); malaria incidence using routine health system data (Malawi); and malaria prevalence using data from the most recent Demographic and Health Survey (DRC). In Kenya the map was used to target preventative interventions, including long-lasting insecticide-treated nets (LLINs) and intermittent preventive treatment in pregnancy (IPTp), whilst in Malawi and DRC the maps were used to target in-door residual spraying (IRS) and LLINs distributions in schools. Maps were also used for operational planning, supply quantification, financial justification and advocacy. Findings from the interviews suggested that decision-makers lacked trust in the modelled PfPR maps when based on only a few empirical data points (Malawi and DRC). CONCLUSIONS: Maps were generally used to identify areas with high prevalence in order to implement specific interventions. Despite the availability of national level modelled PfPR maps in all three countries, they were only used in one country. Perceived utility of malaria risk maps was associated with the epidemiological structure of the country and use was driven by perceived need, understanding (quality and relevance), ownership and trust in the data used to develop the maps.

RESUMO

BACKGROUND: The presence of low or hypo glycaemia in children upon admission to hospital in low income countries is a marker for poor outcome. Fasting during illness may contribute to low blood glucose and caretakers' feeding practices during childhood illnesses may thus play a role in the development of low or hypo glycaemia. This study aims to describe the caretaker's feeding practices and association of fasting with low or hypo glycaemia in sick children in Malawi. METHODS: A mixed method approach was used combining quantitative cross-sectional data for children aged 0-17 years admitted to Queen Elizabeth Central Hospital (QECH), a tertiary hospital in Malawi, with qualitative focus group discussions conducted with caretakers of young children who were previously referred to QECH from the five health centres around QECH. Logistic regression was used to analyse the quantitative data and thematic content analysis was conducted for qualitative data analysis. RESULTS: Data for 5131 children who were admitted through the hospital's Paediatric Accident and Emergency Department (A&E) were analysed whereof 2.1% presented with hypoglycaemia (< 2.5 mmol/l) and 6.6% with low glycaemia (≥2.5mmoll/l - < 5 mmol/l). Fasting for more than eight hours was associated with low glycaemia as well as hypoglycaemia with Adjusted Odds Ratios (AOR) of 2.9 (95% Confidence Interval (CI) of 2.3-3.7) and 4.6, (95% CI 3.0-7.0), respectively. Caretakers demonstrated awareness of the importance of feeding during childhood illness and reported intensified feeding attention to sick children but face feeding challenges when illness becomes severe causing them to seek care at a health facility. CONCLUSION: Results suggests that caretakers understand the importance of feeding during illness and make efforts to intensify feeding a sick child but challenges occur when illness is severe leading to fasting. Fasting among children admitted to hospitals may serve as a marker of severe illness and determine those at risk of low and hypoglycaemia.

RESUMO

BACKGROUND: Acutely sick children in resource-constrained settings who present with hypoglycaemia have poor outcomes. Studies have questioned the current hypoglycaemia treatment cut-off level of 2.5 mmol/l. Improved knowledge about health workers' attitudes towards and management of hypoglycaemia is needed to understand the potential effects of a raised cut-off level. OBJECTIVE: This research explored health workers' perceptions about managing acutely ill children with hypoglycaemia in a Malawian referral hospital. A secondary objective was to explore health workers' opinions about a potential increase in the hypoglycaemia cut-off level. METHODS: We used a qualitative design with semi-structured individual interviews performed with health workers in the Paediatric Accident and Emergency Unit at Queen Elizabeth Central Hospital, Malawi, in October 2016. Data were analysed using latent content analysis. Ethical approval was obtained from the University of Malawi, College of Medicine Research and Ethics Committee P.01/16/1852. RESULTS: Four themes were formed that described the responses. The first, 'Critical and difficult cases need easy treatment', showed that health workers perceived hypoglycaemia as a severe condition that was easily manageable. The second, 'Health system issues', revealed challenges relating to staffing and resource availability. The third, 'From parental reluctance to demand', described a change in parents' attitudes regarding intravenous treatments. The fourth, 'Positive about the change but need more information', exposed health workers' concerns about potential risks of a raised cut-off level for hypoglycaemia treatment, as well as benefits for the patients. CONCLUSIONS: Health workers perceived hypoglycaemia as a severe condition that is easy to manage when the required equipment and supplies are available. Due to the common lack of test equipment and dextrose supplies, health workers have adopted alternative strategies to diagnose and manage hypoglycaemia. A change to the hypoglycaemia treatment cut-off level raised concerns about potential risks, but was also thought to be of benefit for some patients.

RESUMO

BACKGROUND: Based on clinical trial results, the World Health Organization recommends infant HIV testing at age 4-6 weeks and immediate antiretroviral therapy (ART) initiation in all HIV-infected infants. Little is known about the outcomes of HIV-infected infants diagnosed with HIV in the first weeks of life in resource-limited settings. We assessed ART initiation and mortality in the first year of life among infants diagnosed with HIV by 12 weeks of age. METHODS: Cohort of HIV-infected infants in Kinshasa and Blantyre diagnosed before 12 weeks to estimate 12-month cumulative incidences of ART initiation and mortality, accounting for competing risks. Multivariate models were used to estimate associations between infant characteristics and timing of ART initiation. RESULTS: One hundred and twenty-one infants were diagnosed at a median age of 7 weeks (interquartile range, 6-8). The cumulative incidence of ART initiation was 46% [95% confidence interval (CI), 36%, 55%] at 6 months and 70% (95% CI 60%, 78%) at 12 months. Only age at HIV diagnosis was associated with ART initiation by age 6 months, with a subdistribution hazard ratio of 0.70 (95% CI 0.52, 0.91) for each week increase in age at DNA polymerase chain reaction test. The 12-month cumulative incidence of mortality was 20% (95% CI 13%, 28%). CONCLUSIONS: Despite early diagnosis of HIV, ART initiation was slow and mortality remained high, underscoring the complexity in translating clinical trial findings and World Health Organization's guidance into real-life practice. Novel and creative health system interventions will be required to ensure that all HIV-infected infants achieve optimal treatment outcomes under routine care settings.
