Decentralized Heart Failure Management in Neno, Malawi

Background: Cardiovascular disease (CVD) is a major cause of death in Malawi. In rural districts, heart failure (HF) care is limited and provided by non-physicians. The causes and patient outcomes of HF in rural Africa are largely unknown. In our study, non-physician providers performed focused cardiac ultrasound (FOCUS) for HF diagnosis and longitudinal clinical follow-up in Neno, Malawi. Objectives: We described the clinical characteristics, HF categories, and outcomes of patients presenting with HF in chronic care clinics in Neno, Malawi. Methods: Between November 2018 and March 2021, non-physician providers performed FOCUS for diagnosis and longitudinal follow-up in an outpatient chronic disease clinic in rural Malawi. A retrospective chart review was performed for HF diagnostic categories, change in clinical status between enrollment and follow-up, and clinical outcomes. For study purposes, cardiologists reviewed all available ultrasound images. Results: There were 178 patients with HF, a median age of 67 years (IQR 44 – 75), and 103 (58%) women. During the study period, patients were enrolled for a mean of 11.5 months (IQR 5.1–16.5), after which 139 (78%) were alive and in care. The most common diagnostic categories by cardiac ultrasound were hypertensive heart disease (36%), cardiomyopathy (26%), and rheumatic, valvular or congenital heart disease (12.3%). At follow-up, the proportion of New York Heart Association (NYHA) class I patients increased from 24% to 50% (p < 0.001; 95% CI: 31.5 – 16.4), and symptoms of orthopnea, edema, fatigue, hypervolemia, and bibasilar crackles all decreased (p < 0.05). Conclusion: Hypertensive heart disease and cardiomyopathy are the predominant causes of HF in this elderly cohort in rural Malawi. Trained non-physician providers can successfully manage HF to improve symptoms and clinical outcomes in limited resource areas. Similar care models could improve healthcare access in other rural African settings

An investment case for the prevention and management of rheumatic heart disease in the African Union 2021-30: a modelling study.

BACKGROUND: Despite declines in deaths from rheumatic heart disease (RHD) in Africa over the past 30 years, it remains a major cause of cardiovascular morbidity and mortality on the continent. We present an investment case for interventions to prevent and manage RHD in the African Union (AU). METHODS: We created a cohort state-transition model to estimate key outcomes in the disease process, including cases of pharyngitis from group A streptococcus, episodes of acute rheumatic fever (ARF), cases of RHD, heart failure, and deaths. With this model, we estimated the impact of scaling up interventions using estimates of effect sizes from published studies. We estimated the cost to scale up coverage of interventions and summarised the benefits by monetising health gains estimated in the model using a full income approach. Costs and benefits were compared using the benefit-cost ratio and the net benefits with discounted costs and benefits. FINDINGS: Operationally achievable levels of scale-up of interventions along the disease spectrum, including primary prevention, secondary prevention, platforms for management of heart failure, and heart valve surgery could avert 74 000 (UI 50 000-104 000) deaths from RHD and ARF from 2021 to 2030 in the AU, reaching a 30·7% (21·6-39·0) reduction in the age-standardised death rate from RHD in 2030, compared with no increase in coverage of interventions. The estimated benefit-cost ratio for plausible scale-up of secondary prevention and secondary and tertiary care interventions was 4·7 (2·9-6·3) with a net benefit of $2·8 billion (1·6-3·9; 2019 US$) through 2030. The estimated benefit-cost ratio for primary prevention scale-up was low to 2030 (0·2, <0·1-0·4), increasing with delayed benefits accrued to 2090. The benefit-cost dynamics of primary prevention were sensitive to the costs of different delivery approaches, uncertain epidemiological parameters regarding group A streptococcal pharyngitis and ARF, assumptions about long-term demographic and economic trends, and discounting. INTERPRETATION: Increased coverage of interventions to control and manage RHD could accelerate progress towards eradication in AU member states. Gaps in local epidemiological data and particular components of the disease process create uncertainty around the level of benefits. In the short term, costs of secondary prevention and secondary and tertiary care for RHD are lower than for primary prevention, and benefits accrue earlier.

Hochschulkommunikation in Online­-Medien und Social Media

Hochschulen kommunizieren zunehmend online und auf Social Media. Nichtsdestotrotz ist die Forschung, die sich mit Hochschulen als Kommunikatoren in der Online-Welt, den Inhalten ihrer Online-Kommunikation und mit deren Nutzung und Wirkung auseinandersetzt, noch stark fragmentiert und hinsichtlich zentraler Fragen begrenzt. Der vorliegende Beitrag erschliesst dieses Forschungsfeld, identifiziert Foki der entsprechenden Studien und stellt den Forschungsstand zu den Inhalten der Online-Kommunikation von Hochschulen, zu ihrer Rolle als Online- Kommunikatoren sowie zur Nutzung und Wirkung dieser Kommunikation dar. Er zeigt unter anderem, dass sich Hochschulen der Bedeutung unterschiedlicher Online-Medien bewusst sind und diese entsprechend bespielen, dass aber gerade Hochschulen im deutschsprachigen Raum diesbezüglich nicht zu den Vorreitern gehören. Online-Medien werden v.a. als zusätzliche Kanäle für traditionelle Inhalte genutzt. Diese Angebote richten sich überwiegend an Studierende und werden oft auf Basis einer marketingorientierten Perspektive aufbereitet. Der Beitrag macht zudem eine beträchtliche Zahl blinder Flecken in der Forschung deutlich: Er zeigt, dass sich Studien bis dato überwiegend auf den angloamerikanischen Raum und dessen Hochschulsystem beziehen, dass wenige Studien auf einer klaren theoretischen Grundlage operieren und die Nutzung von Online-Kommunikation selten gemeinsam mit übergeordneten Kommunikationsstrategien analysiert wird

Decentralization and integration of advanced cardiac care for the world’s poorest billion through the PEN-plus strategy for severe chronic non-communicable disease

See http://creativecommons.org/ licenses/by/4.0/.Rheumatic and congenital heart disease, cardiomyopathies, and hypertensive heart disease are major causes of suffering and death in low- and lower middle-income countries (LLMICs), where the world's poorest billion people reside. Advanced cardiac care in these counties is still predominantly provided by specialists at urban tertiary centers, and is largely inaccessible to the rural poor. This situation is due to critical shortages in diagnostics, medications, and trained healthcare workers. The Package of Essential NCD Interventions - Plus (PEN-Plus) is an integrated care model for severe chronic noncommunicable diseases (NCDs) that aims to decentralize services and increase access. PEN-Plus strategies are being initiated by a growing number of LLMICs. We describe how PEN-Plus addresses the need for advanced cardiac care and discuss how a global group of cardiac organizations are working through the PEN-Plus Cardiac expert group to promote a shared operational strategy for management of severe cardiac disease in high-poverty settings.The PEN-Plus Cardiac Expert group is supported through grant #192269 from the American Heart Association.info:eu-repo/semantics/publishedVersio
