Diagnostic point-of-care ultrasound in medical inpatients at Queen Elizabeth Central Hospital, Malawi: an observational study of practice and evaluation of implementation

Background: In less well-resourced settings, where access to radiology services is limited, point-of-care ultra-sound (POCUS) can be used to assess patients and guide clinical management. The aim of this study was to describe ultrasound practice in the assessment of medical inpatients at Queen Elizabeth Central Hospital, Blantyre, Malawi, and evaluate uptake and impact of POCUS following the introduction of a training programme at the college of Medicine, Blantyre, Malawi. Methods: A weekly prospective record review of sequential adult medical inpatients who had received an ultrasound examination was conducted. Results: Of 835 patients screened, 250 patients were included; 267 ultrasound examinations were performed,of which 133 (50%) were POCUS (defined as performed by a clinician at the bedside). The time from request toperformance of examination was shorter for POCUS examinations than radiology department ultrasound (RDUS)(median 0 [IQR 0–2, range 0–11] vs 2 [IQR 1–4, range 0–15] d, p=0.002); 104/133 (78.2%) POCUS and 90/133(67.7%) RDUS examinations were deemed to have an impact on management. Conclusion: Following the introduction of a training programme in POCUS, half of all ultrasound examinations were delivered as POCUS. POCUS was performed rapidly and impacted on patient management. POCUS may relieve the burden on radiology services in less well-resourced settings

Estimating the economic burden of typhoid in children and adults in Blantyre, Malawi: A costing cohort study.

BackgroundTyphoid causes preventable death and disease. The World Health Organization recommends Typhoid Conjugate Vaccine for endemic countries, but introduction decisions depend on cost-effectiveness. We estimated household and healthcare economic burdens of typhoid in Blantyre, Malawi.MethodsIn a prospective cohort of culture-confirmed typhoid cases at two primary- and a referral-level health facility, we collected direct medical, non-medical costs (2020 U.S. dollars) to healthcare provider, plus indirect costs to households.ResultsFrom July 2019-March 2020, of 109 cases, 63 (58%) were 40% of non-food monthly household expenditure, occurred in 48 (44%) households.ConclusionsTyphoid can be economically catastrophic for families, despite accessible free medical care. Typhoid is costly for government healthcare provision. These data make an economic case for TCV introduction in Malawi and the region and will be used to derive vaccine cost-effectiveness

Lessons learnt from the rapid implementation of reusable personal protective equipment for COVID-19 in Malawi

The SARS-CoV-2 pandemic has challenged health systems and healthcare workers worldwide. Access to personal protective equipment (PPE) is essential to mitigate the risk of excess mortality in healthcare providers. In Malawi, the cost of PPE represents an additional drain on available resources. In the event of repeated waves of disease over several years, the development of sustainable systems of PPE is essential. We describe the development, early implementation and rapid scale up of a reusable gown service at a tertiary-level hospital in Blantyre, Malawi. Challenges included healthcare worker perceptions around the potential of reduced efficacy of cotton gowns, the need to plan for surge capacity and the need for ongoing training of laundry staff in safety and hygiene procedures. Benefits of the system included increased coverage, decreased cost and reduced waste disposal. The implementation of a reusable cotton gown service is feasible, acceptable and cost-effective in tertiary centres providing specialist COVID-19 care at the height of the pandemic. This innovation could be expanded beyond low-income settings

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
