Individual and population level costs and health-related quality of life outcomes of third-generation cephalosporin resistant bloodstream infection in Blantyre, Malawi.

Data which accurately enumerate the economic costs of antimicrobial resistance (AMR) in low- and middle- income countries are essential. This study aimed to quantify the impact of third-generation cephalosporin resistant (3GC-R) bloodstream infection (BSI) on economic and health related quality of life outcomes for adult patients in Blantyre, Malawi. Participants were recruited from a prospective, longitudinal cohort study of hospitalised patients with bloodstream infection caused by Enterobacterales at Queen Elizabeth Central Hospital (QECH). Primary costing studies were used to estimate the direct medical costs associated with the inpatient stay. Recruited participants were asked about direct non-medical and indirect costs associated with their admission and their health-related quality of life was measured using the EuroQol EQ-5D questionnaire. Multiple imputation was undertaken to account for missing data. Costs were adjusted to 2019 US Dollars. Cost and microbiology surveillance data from QECH, Blantyre was used to model the annual cost of, and quality-adjusted life years lost to, 3GC-R and 3GC-Susceptible BSI from 1998 to 2030 in Malawi. The mean health provider cost per participant with 3GC-R BSI was US$110.27 (95%CR; 22.60-197.95), higher than for those with 3GC-S infection. Patients with resistant BSI incurred an additional indirect cost of US$155.48 (95%CR; -67.80, 378.78) and an additional direct non-medical cost of US$20.98 (95%CR; -36.47, 78.42). Health related quality of life outcomes were poor for all participants, but participants with resistant infections had an EQ-5D utility score that was 0.167 (95% CR: -0.035, 0.300) lower than those with sensitive infections. Population level burden estimates suggest that in 2016, 3GC-R accounted for 84% of annual societal costs from admission with bloodstream infection and 82% of QALYs lost. 3GC-R bloodstream infection was associated with higher health provider and patient level costs than 3GC-S infection, as well as poorer HRQoL outcomes. We demonstrate a substantial current and future economic burden to society as a result of 3GC-R E. coli and Klebsiella spp. BSI, data urgently needed by policy makers to provide impetus for implementing strategies to reduce AMR.

Comparative whole genome analysis reveals re-emergence of human Wa-like and DS-1-like G3 rotaviruses after Rotarix vaccine introduction in Malawi.

G3 rotaviruses rank among the most common rotavirus strains worldwide in humans and animals. However, despite a robust long-term rotavirus surveillance system from 1997 at Queen Elizabeth Central Hospital in Blantyre, Malawi, these strains were only detected from 1997 to 1999 and then disappeared and re-emerged in 2017, 5 years after the introduction of the Rotarix rotavirus vaccine. Here, we analysed representative twenty-seven whole genome sequences (G3P[4], n = 20; G3P[6], n = 1; and G3P[8], n = 6) randomly selected each month between November 2017 and August 2019 to understand how G3 strains re-emerged in Malawi. We found four genotype constellations that were associated with the emergent G3 strains and co-circulated in Malawi post-Rotarix vaccine introduction: G3P[4] and G3P[6] strains with the DS-1-like genetic backbone genes (G3-P[4]-I2-R2-C2-M2-A2-N2-T2-E2-H2 and G3-P[6]-I2-R2-C2-M2-A2-N2-T2-E2-H2), G3P[8] strains with the Wa-like genetic backbone genes (G3-P[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1), and reassortant G3P[4] strains consisting of the DS-1-like genetic backbone genes and a Wa-like NSP2 (N1) gene (G3-P[4]-I2-R2-C2-M2-A2-N1-T2-E2-H2). Time-resolved phylogenetic trees demonstrated that the most recent common ancestor for each ribonucleic acid (RNA) segment of the emergent G3 strains was between 1996 and 2012, possibly through introductions from outside the country due to the limited genetic similarity with G3 strains which circulated before their disappearance in the late 1990s. Further genomic analysis revealed that the reassortant DS-1-like G3P[4] strains acquired a Wa-like NSP2 genome segment (N1 genotype) through intergenogroup reassortment; an artiodactyl-like VP3 through intergenogroup interspecies reassortment; and VP6, NSP1, and NSP4 segments through intragenogroup reassortment likely before importation into Malawi. Additionally, the emergent G3 strains contain amino acid substitutions within the antigenic regions of the VP4 proteins which could potentially impact the binding of rotavirus vaccine-induced antibodies. Altogether, our findings show that multiple strains with either Wa-like or DS-1-like genotype constellations have driven the re-emergence of G3 strains. The findings also highlight the role of human mobility and genome reassortment events in the cross-border dissemination and evolution of rotavirus strains in Malawi necessitating the need for long-term genomic surveillance of rotavirus in high disease-burden settings to inform disease prevention and control.

Cost-effectiveness analysis of typhoid conjugate vaccines in an outbreak setting: a modeling study

BackgroundSeveral prolonged typhoid fever epidemics have been reported since 2010 throughout eastern and southern Africa, including Malawi, caused by multidrug-resistant Salmonella Typhi. The World Health Organization recommends the use of typhoid conjugate vaccines (TCVs) in outbreak settings; however, current data are limited on how and when TCVs might be introduced in response to outbreaks.MethodologyWe developed a stochastic model of typhoid transmission fitted to data from Queen Elizabeth Central Hospital in Blantyre, Malawi from January 1996 to February 2015. We used the model to evaluate the cost-effectiveness of vaccination strategies over a 10-year time horizon in three scenarios: (1) when an outbreak is likely to occur; (2) when an outbreak is unlikely to occur within the next ten years; and (3) when an outbreak has already occurred and is unlikely to occur again. We considered three vaccination strategies compared to the status quo of no vaccination: (a) preventative routine vaccination at 9 months of age; (b) preventative routine vaccination plus a catch-up campaign to 15 years of age; and (c) reactive vaccination with a catch-up campaign to age 15 (for Scenario 1). We also explored variations in outbreak definitions, delays in implementation of reactive vaccination, and the timing of preventive vaccination relative to the outbreak.ResultsAssuming an outbreak occurs within 10 years, we estimated that the various vaccination strategies would prevent a median of 15–60% of disability-adjusted life-years (DALYs). Reactive vaccination was the preferred strategy for WTP values of $0–300 per DALY averted. For WTP values > $300, introduction of preventative routine TCV immunization with a catch-up campaign was the preferred strategy. Routine vaccination with a catch-up campaign was cost-effective for WTP values above $890 per DALY averted if no outbreak occurs and > $140 per DALY averted if implemented after the outbreak has already occurred.ConclusionsCountries for which the spread of antimicrobial resistance is likely to lead to outbreaks of typhoid fever should consider TCV introduction. Reactive vaccination can be a cost-effective strategy, but only if delays in vaccine deployment are minimal; otherwise, introduction of preventive routine immunization with a catch-up campaign is the preferred strategy.

Characterising paediatric mortality during and after acute illness in Sub-Saharan Africa and South Asia: a secondary analysis of the CHAIN cohort using a machine learning approach

A better understanding of which children are likely to die during acute illness will help clinicians and policy makers target resources at the most vulnerable children. We used machine learning to characterise mortality in the 30-days following admission and the 180-days after discharge from nine hospitals in low and middle-income countries (LMIC). A cohort of 3101 children aged 2-24 months were recruited at admission to hospital for any acute illness in Bangladesh (Dhaka and Matlab Hospitals), Pakistan (Civil Hospital Karachi), Kenya (Kilifi, Mbagathi, and Migori Hospitals), Uganda (Mulago Hospital), Malawi (Queen Elizabeth Central Hospital), and Burkina Faso (Banfora Hospital) from November 2016 to January 2019. To record mortality, children were observed during their hospitalisation and for 180 days post-discharge. Extreme gradient boosted models of death within 30 days of admission and mortality in the 180 days following discharge were built. Clusters of mortality sharing similar characteristics were identified from the models using Shapley additive values with spectral clustering. Anthropometric and laboratory parameters were the most influential predictors of both 30-day and post-discharge mortality. No WHO/IMCI syndromes were among the 25 most influential mortality predictors of mortality. For 30-day mortality, two lower-risk clusters (N=1915, 61%) included children with higher-than-average anthropometry (1% died, 95% CI: 0-2), and children without signs of severe illness (3% died, 95% CI: 2-4%). The two highest risk 30-day mortality clusters (N=118, 4%) were characterised by high urea and creatinine (70% died, 95% CI: 62-82%); and nutritional oedema with low platelets and reduced consciousness (97% died, 95% CI: 92-100%). For post-discharge mortality risk, two low-risk clusters (N=1753, 61%) were defined by higher-than-average anthropometry (0% died, 95% CI: 0-1%), and gastroenteritis with lower-than-average anthropometry and without major laboratory abnormalities (0% died, 95% CI: 0-1%). Two highest risk post-discharge clusters (N=267, 9%) included children leaving against medical advice (30% died, 95% CI: 25-37%), and severely-low anthropometry with signs of illness at discharge (46% died, 95% CI: 34-62%). WHO clinical syndromes are not sufficient at predicting risk. Integrating basic laboratory features such as urea, creatinine, red blood cell, lymphocyte and platelet counts into guidelines may strengthen efforts to identify high-risk children during paediatric hospitalisations.

A qualitative study exploring hand hygiene practices in a neonatal unit in Blantyre, Malawi: implications for controlling healthcare-associated infections

Background: Neonatal sepsis is responsible for a considerable burden of morbidity and mortality in sub-Saharan African countries. Outcomes from neonatal sepsis are worsening due to increasing rates of antimicrobial resistance. Sub-optimal Infection Prevention and Control (IPC) practices of health care workers and caregivers are important drivers of infection transmission. The Chatinkha Neonatal Unit at Queen Elizabeth Central Hospital, Blantyre, Malawi has experienced multiple outbreaks of neonatal sepsis, associated with drug resistant Klebsiella pneumoniae. We aimed to understand the barriers to implementation of optimal IPC focusing on hand hygiene practice. Methods: We used a qualitative research methodology to meet the study aim. Combining participant observation (PO) over a seven-month period with semi structured interviews (SSI) to provide an in-depth understanding of activities relating to hygiene and IPC existing on the ward. Results: While most staff and some caregivers, had a good understanding of ideal IPC and understood the importance of good handwashing practices, they faced substantial structural limitations, and scarce resources (both material and human) which made implementation challenging. For staff, the overwhelming numbers of patients meant the workload was often unmanageable and practicing optimal IPC was challenging. Caregivers lacked access to basic amenities, including linen and chairs, meaning that it was almost impossible for them to maintain good hand hygiene. Limited access to soap and the erratic water supply for both caregivers and healthcare workers further worsened the situation. Communication challenges between different cadres of staff and with patient caregivers meant that those handling neonates and cleaning the wards were often unaware of outbreaks of drug resistant infection. Conclusion: For IPC to be improved, interventions need to address the chronic shortages of material resources and create an enabling environment for HCWs and patient caregivers.

Ultrasound appearance of the kidney among radiology department attendees of a tertiary centre in Malawi.

Background: Diagnostic and therapeutic decisions in nephrology in low-resource settings are frequently based on ultrasound assessment of kidney size. An understanding of reference values is critical, particularly given the rise of non-communicable disease and the expanding availability of point-of-care ultrasound. However, there is a paucity of normative data from African populations. We determined estimates of kidney ultrasound measures, including kidney size based on age, sex, and HIV status, among apparently healthy outpatient attendees of Queen Elizabeth Central hospital radiology department, Blantyre, Malawi. Methods: We performed a cross-sectional cohort study of 320 adults attending the radiology department between October 2021 and January 2022. Bilateral kidney ultrasound was performed on all participants using a portable Mindray DP-50 machine and a 5MHz convex probe. The sample was stratified by age, sex, and HIV status. Predictive linear modelling was used to construct reference ranges for kidney size estimating the central 95 percentiles of 252 healthy adults. Exclusion criteria for the healthy sample were known kidney disease, hypertension, diabetes, BMI > 35, heavy alcohol intake, smoking and ultrasonographic abnormalities. Results: There were 162/320 (51%) male participants. The median age was 47 (interquartile range [IQR] 34-59). Among people living with HIV 134/138 (97%) were receiving antiretroviral therapy. Men had larger average kidney sizes: mean 9.68 cm (SD 0.80 cm), compared to 9.46 cm (SD 0.87 cm) in women ( p = 0.01). Average kidney sizes in people living with HIV were not significantly different from those who were HIV-negative, 9.73 cm (SD 0.93 cm) versus 9.58 cm (SD 0.93 cm) ( p = 0.63). Conclusions: This is the first report of the apparently healthy kidney size in Malawi. Predicted kidney size ranges may be used for reference in the clinical assessment of kidney disease in Malawi.

Invasiveness potential of pneumococcal serotypes in children after introduction of PCV13 in Blantyre, Malawi

IntroductionThe introduction of PCV13 to the Malawi infant immunization schedule in 2011 has been associated with reduced disease from Streptococcus pneumoniae. Improved understanding of serotypes with high invasive potential can guide future vaccination interventions. We aimed to estimate pneumococcal serotypes associated with acute respiratory infection (ARI) and invasive pneumococcal disease (IPD) in hospitalized children in Blantyre, Malawi.MethodsWe analysed data from healthy children under 5 years in the community in Blantyre and children admitted to Queen Elizabeth Central Hospital with ARI between 2015 and 2018. Nasopharyngeal swabs from children were tested for S. pneumoniae and serotyped by latex agglutination if positive. We analysed culture-positive blood and cerebrospinal fluid samples from admitted children between 2012 and 2018 to identify cases of IPD after the introduction of PCV13. We calculated the age-adjusted odds ratio (OR) of carriage for S. pneumoniae vaccine serotypes (VT) comparing those with ARI to healthy children. We also calculated age-adjusted ORs comparing serotypes causing IPD to carriage in the community with OR > 1 indicating high invasive potential.ResultsSerotypes 5 (OR 24.73 [95% CI 7.90–78.56] p < 0.001), 1 (OR 23.38 [95% CI 9.75–56.06] p < 0.001), and 6B (OR 4.73 [95% CI 1.66–11.64] p = 0.001) had high invasive potential. Serotype 6B was no longer significant (OR 1.34 [95% CI 0.07–6.87] p = 0.777) in a sensitivity analysis accounting for year of recruitment. The prevalence of S. pneumoniae carriage in the community was 72.6% [95% CI 71.3–74.0] (3078/4238) and 23.4% (719/3078) of positive community samples were VT. The carriage prevalence in those hospitalised with ARI was 45.5% [95% CI 42.1–48.9] (389/855) and 43.8% of hospital attendees reported antibiotic use prior to admission. We did not identify significant associations with carriage of any serotypes in those with ARI.ConclusionsPneumococcal serotypes 5 and 1 are associated with high invasive potential. Despite high community pneumococcal carriage, pre-hospital antibiotic usage likely reduces pneumococcal detection among children admitted in this setting and further research is needed to investigate serotypes associated with ARI. Data from this study can guide future preventative vaccination strategies in Malawi.

‘It is the child with the big head’ – Primary healthcare providers’ perceptions of paediatric hydrocephalus in Blantyre, Malawi: A qualitative study

ABSTRACT Children in Africa are disproportionately burdened by the neurosurgical condition hydrocephalus. In Blantyre, Malawi, paediatric hydrocephalus represents the majority of surgical procedures performed in the neurosurgical department at Queen Elizabeth Central Hospital. To reduce morbidity and mortality, timely detection followed by referral from surrounding primary health centres is crucial. Aiming to explore perceptions and identify enablers and barriers to detection and referral, we conducted a qualitative study among primary healthcare providers (n = 30) from ten health centres in Blantyre district. Using a semi-structured interview-guide, we audio-recorded and transcribed the interviews before conducting a thematic analysis. One main finding is that there is a potential to improve detection through head circumference measurements, which is the recommended way to detect hydrocephalus early, yet healthcare providers did not carry this out systematically. They described the health passport provided by the Malawian Ministry of Health as an important tool for clinical communication. However, head circumference growth charts are not included. To optimise outcomes for paediatric hydrocephalus we suggest including head circumference growth charts in the health passports. To meet the need for comprehensive management of paediatric hydrocephalus, we recommend more research from the continent, focusing on bridging the gap between primary care and neurosurgery.

High prevalence of dyslipidaemia among persons with diabetes mellitus and hypertension at a tertiary hospital in Blantyre, Malawi

BackgroundDyslipidaemia drives the process of atherosclerosis, and hence a significant modifiable risk factor complicating hypertension and diabetes. In Malawi, the prevalence, screening and management of dyslipidaemia among persons with diabetes mellitus have not been reported. This study aimed to investigate the prevalence, biochemical characteristics, screening and management practices for dyslipidaemia among persons with diabetes mellitus, hypertension, and diabetes mellitus and hypertension comorbidity at Queen Elizabeth Central hospital in Blantyre, Malawi.MethodsThis was a cross-sectional study conducted in 2021. A total of 256 adult participants (diabetes mellitus = 100); hypertension = 100; both conditions = 56) were included. Medical data and anthropometric measurements were recorded. Blood samples were analysed for HbA1C and serum lipids. Associated risk factors for dyslipidaemia were also assessed.ResultsDyslipidaemia was prevalent in 58%, 55%, and 70% of participants with diabetes mellitus, hypertension, and both conditions. Low-density lipoprotein cholesterol (LDL-C) dyslipidaemia was the most common in all participant groups. Participants with both diabetes and hypertension had 2.4 times (95% CI 1.2–4.6) increased risk of LDL-C dyslipidaemia than those with diabetes alone (p < 0.02). Being overweight or obese and age over 30 years were risk factors for dyslipidaemia in participants with diabetes mellitus alone (OR 1.3 (95% CI 1.1–1.6), p < 0.04, and OR 2.2 (95% CI 1.2–4.7) (p < 0.01), respectively. Overweight and obesity predicted LDL-C dyslipidaemia in hypertensive patients (OR 3.5 (95% CI 1.2–9.9) p < 0.001). Poorly controlled hypertension and the use of beta-blockers and thiazide diuretics predicted dyslipidaemia among patients with both diabetes mellitus and hypertension (OR 6.50 CI 1.45–29.19; and OR 5.20 CI 1.16–23.36 respectively). None of the participants had a lipogram performed before the study or were on lipid-lowering therapy.ConclusionsDyslipidaemia with LDL-C derangement was highly prevalent, especially in individuals with both diabetes mellitus and hypertension, and there was absent use of lipid-lowering therapy. Screening and managing dyslipidaemia should be reinforced to reduce the risk of cardiovascular complications in this population at increased risk.

Prevalence of Dyslipidaemia, Obesity and Vitamin d Insufficiency Among Patients Attending the Diabetic Clinic at Queen Elizabeth Central Hospital in Malawi

BackgroundDyslipidaemia, obesity and vitamin D insufficiency are important risk factors for cardiovascular disease and may increase the risk for severe COVID-19 among individuals with Diabetes mellitus. ObjectiveTo investigate the prevalence of dyslipidaemia, obesity and vitamin D insufficiency among patients attending the diabetes clinic at Queen Elizabeth Central Hospital in Blantyre, Malawi. MethodsA total of 102 participants were included in the cross-sectional study. Medical data were collected, and anthropometric measurements were performed. Blood samples were collected for HbA1C, serum lipogram and vitamin D analyses. Associated risk factors for dyslipidaemia and vitamin D insufficiency were assessed. ResultsA proportion of 74% of the participants had dyslipidaemia. Low-density lipoprotein-cholesterol dyslipidaemia was the most common form of dyslipidaemia (52%). Overweight and obesity was prevalent in 58% of the participants. The median (IQR) HBA1C level was 11% (9-14 %). Overweight or obesity and age over 30 years were risks for dyslipidaemia (RR 1.3 (95% CI 1.1 – 1.6), p=0.04, and RR 2.2 (95% CI 1.2 – 4.7) p=0.003, respectively. The prevalence of vitamin D insufficiency in the study group was 76%. HBA1C of > 7% was positively associated with vitamin D insufficiency (RR 1.6 (CI 1.0 – 2.8), p=0.02). ConclusionsDyslipidaemia, obesity, and vitamin D insufficiency were highly prevalent in the study group. Poorly controlled blood glucose was associated with vitamin D insufficiency. The high prevalence of dyslipidaemia, obesity and vitamin D deficiency are the possible precipitating factors for the increasing rates of cardiovascular events and COVID-19 severity among patients with diabetes in Malawi.

Health care workers and key policy informant's knowledge of the use of calcium and low dose aspirin for prevention of preeclampsia in Malawian women.

This study investigated health care workers and key policy informant's knowledge, and barriers to the use of calcium and aspirin for preventing preeclampsia in Blantyre and Lilongwe, Malawi. A descriptive cross-sectional formative study using semi-structured In-Depth Interview (IDIs) was conducted at Queen Elizabeth Central Hospital (QECH), Reproductive Health Directorate, and the United Nations Population Development Fund (UNFPA) Office in 2021. Data was analyzed using NVIVO™ software. Thematic content analysis was used to analyze and interpret the findings. Emerging themes were then developed inductively and deductively. Doctors had greater knowledge of the use of calcium and aspirin for prevention of preeclampsia compared to nurses and key policy informants. Lack of knowledge, patient's late presentation, scarcity of calcium tablets and delays in implementing new guidelines were the barriers to use identified. This study shows that there are health care worker and policy level barriers that affect the implementation of calcium and aspirin use for the prevention of preeclampsia in Malawian women.

Ultrasound appearance of the kidney among radiology department attendees of a tertiary centre in Malawi.

Background: Diagnostic and therapeutic decisions in nephrology in low-resource settings are frequently based on ultrasound assessment of kidney size.

Of those whose HIV status was known and positive, 138/308 (45%), 134/138 (97%) were receiving antiretroviral therapy. Men had larger average kidney sizes: mean 9.68 cm (SD 0.80 cm), compared to 9.46 cm (SD 0.87 cm) in women ( p = 0.01). Average kidney sizes in HIV-positive participants were not significantly different from those who were HIV-negative, 9.73 cm (SD 0.93 cm) versus 9.58 cm (SD 0.93 cm) ( p = 0.63). Conclusions: This is the first report of the apparently healthy kidney size in Malawi. Predicted kidney size ranges may be used for reference in the clinical assessment of kidney disease in Malawi.

Effect of resistance to third-generation cephalosporins on morbidity and mortality from bloodstream infections in Blantyre, Malawi: a prospective cohort study

The burden of antimicrobial resistance is a major threat to global health; however, prospective clinical outcome data from Africa are scarce. In Malawi, third-generation cephalosporins are the antibiotics of choice in patients admitted to hospital despite a rapid proliferation of resistance to these drugs. We aimed to quantify the effect of resistance to third-generation cephalosporins on mortality and length of hospital stay among patients with bloodstream infections. We did a prospective cohort study of patients admitted to Queen Elizabeth Central Hospital in Blantyre, Malawi. Patients of all ages who had positive blood cultures for Enterobacterales were included, with the exception of those from the genus Salmonella, and were followed up for 180 days. We characterised blood culture isolates using whole-genome sequencing and used Cox regression models to estimate the effect of resistance to third-generation cephalosporins on length of hospital stay, in-hospital mortality, and survival. Between Jan 31, 2018, and Jan 13, 2020, we recruited 326 patients, from whom 220 (68%) of 326 isolates were resistant to third-generation cephalosporins. The case fatality proportion was 45% (99 of 220) in patients with bloodstream infections that were resistant to third-generation cephalosporins, and 34% (36 of 106) in patients with bloodstream infections that were sensitive to third-generation cephalosporins. Resistance to third-generation cephalosporins was associated with an increased probability of in-hospital mortality (hazard ratio [HR] 1·44, 95% CI 1·02-2·04), longer hospital stays (1·5 days, 1·0-2·0) and decreased probability of discharge alive (HR 0·31, 0·22-0·45). Whole-genome sequencing showed a high diversity of sequence types of both Escherichia coli and Klebsiella pneumoniae. Although isolates associated with death were distributed across clades, we identified three E coli clades (ST410, ST617, and ST648) that were isolated from 14 patients who all died. Resistance to third-generation cephalosporins is associated with increased mortality and longer hospital stays in patients with bloodstream infections in Malawi. These data show the urgent need for allocation of resources towards antimicrobial resistance mitigation strategies in Africa. Wellcome Trust and Wellcome Asia and Africa Programme.

An audit of Heart failure management among ambulatory adult patients at Queen Elizabeth Central Hospital (QECH), Malawi.

There are limited data on the clinical characteristics and use of guideline directed medical therapy among patients with heart failure in Malawi. We conducted a study to assess patient characteristics and clinical management given to heart failure patients at Queen Elizabeth Central hospital in Malawi. In a cross sectional study, patients with a diagnosis of heart failure who were followed up in the adult chest clinic at QECH were recruited to ascertain their characteristics and the therapy they were receiving. Echocardiograms and electrocardiograms were performed to identify abnormalities. A total of 79 patients were recruited and 62% (49 out of 79) were female. The median age was 60 years (IQR 40.5-70.5). Most patients were hypertensive with NYHA (New York Heart Association) class I and II symptoms. Left ventricular(LV) systolic dysfunction was found in 55% (36 out of 65), with 68% (39 out of 65) having features of left ventricular remodeling. Most patients were on at least a single neurohormonal drug with 77% (61 out of 79) on ACEI (angiotensin converting enzyme inhibitor), 52% (42 out of 79) on a beta blocker and 34%(27 out of 79) on aldosterone antagonists. The recommended doses of medications were achieved in 14% (9 out 61), 24% (10 out 42), 22% (6 out of 27) on ACEI, beta blockers and aldosterone antagonists respectively. Hypertension is the commonest comorbidity in patients with heart failure, who are mostly females with NYHA class I or II symptoms. Most had LV remodeling changes and are on at least one neurohormonal antagonist but most remain sub optimally treated.

Quality of life of primary caregivers of children living with cerebral palsy at two clinics in Blantyre, Malawi.

In Malawi, Primary Caregivers (PCGs) of children living with Cerebral Palsy report challenges such as physical strain and lack of resources that affect care giving. Although such experiences affect the PCGs' Quality of Life (QoL), there is paucity of data for Malawi. Understanding their QoL would inform establishment of holistic intervention(s) tailored to meet their needs. Therefore, the purposes of this study were to determine QoL of PCGs of the children who were receiving rehabilitation at Queen Elizabeth Central Hospital (QECH) and Feed the Children (FtC), to identify PCG's and children's socio-demographic factors that may attribute to the perceived QoL, and to compare the PCGs' QoL between the sites. A cross-sectional study was conducted from January to April 2019 on 142 PCGs of children aged between 2 and 18 years of age. All PCGs who were employed for the child-care, or had a chronic sickness were excluded. QoL was assessed using the World Health Organization Brief questionnaire, with a cut-off point of <60% for poor QoL. The severity of children's impairments was assessed using Gross Motor Function Classification System. Descriptive and inferential statistics were conducted to analyze the data. The PCGs' age, sex, marital status and level of education, and child's severity of impairment were compared with QoL. The majority of PCGs (61.30%) had poor QoL, and there was no significant difference in overall QoL of the PCGs between the sites (p<0.31). The PCGs at QECH had significantly higher physical domain mean scores than at FtC (U=1906, p<0.01). The overall QoL differed significantly across the marital statuses of the PCGs (p<0.03). The study has established that most PCGs at both sites possess poor QoL. However, there is need to investigate how the rehabilitation institutions and workers influence the QoL of the PCGs within and between the facilities.

Establishing neurosurgery in Malawi – the story of a fruitful collaboration

Until 2011 there was no neurosurgical service in Malawi apart from simple shunt surgery. Since then, little by little, a neurosurgical unit has been built up at Queen Elizabeth Central Hospital in Blantyre, with support from Oslo University Hospital.&#x0D; Today, the neurosurgical unit has one operating room and a 6-bed high dependency unit for postoperative care. Three neurosurgeons, two young trainees, and a team of dedicated nurses and assistants perform a total of 400 surgeries annually. Three quarters of the patients are children. An increasing proportion of the operations are craniotomies.&#x0D; A CT scanner was installed in December 2020 and will probably lead to increased demand for general neurosurgery, in particular for trauma surgery. A second operating room and a 30-bed unit are needed in the near future. Two more trainees will start in 2022.&#x0D; The plan is to have a sustainable, self-supporting service in 5-10 years’ time.

Meeting demand-Obstetric hemorrhage and blood availability in Malawi, a qualitative study.

Postpartum haemorrhage (PPH) is the leading cause of maternal mortality in Malawi. Despite the presence of a centralized institution supplying blood and blood products for hospitals across the country, a lack of timely blood transfusion has been identified as a critical barrier to successful PPH management. This study aims to understand the factors that affect the blood delivery pipeline and adequate access to blood products for postpartum haemorrhage patients. Qualitative data were collected through in-depth interviews with key stakeholders across the blood delivery pipeline. Interviews were conducted from July 2020 to January 2021 at Queen Elizabeth Central Hospital and Mulanje District Hospital, a referral and district hospital respectively, as well as the Malawi Blood Transfusion Service. Line by line, open coding was used to perform a thematic analysis of the data using Nvivo and Atlas.ti software. Five key themes were identified: 1) Lack of blood availability due to an inadequate donor pool, 2) Transportation of blood products and PPH patients is impeded by distance to target sites and competing interests for blood delivery vehicles, 3) The Malawi Blood Transfusion Service has difficulty meeting demand for blood products due to inadequate funding and difficulty retaining blood donors, 4) Current PPH management protocols and practices lead to delays due to inconsistent guidelines on delivery and analysis of patient samples, and 5) Communication between health cadres is inconsistent and affected by a lack of adequate resources. Barriers to timely blood transfusion for PPH patients exist across the blood delivery pipeline. While an investment of infrastructure would alleviate many obstacles, several solutions identified in this study can be implemented without additional resources, such as establishing joint department meetings to improve communication between health cadres. Ultimately, given a resource limited setting, it may be worth considering de-centralizing the blood supply.
