Chronic respiratory disease in adult outpatients in three African countries: a cross-sectional study

Primary Causes and Direct Medical Cost of Heart Failure Among Adults Admitted with Acute Decompensated Heart Failure in a Public Tertiary Hospital, Kenya

Background

Heart failure (HF) is a major contributor to cardiovascular morbidity and mortality. Adversely impacting health outcomes in Kenya and other developing countries, data on the direct medical cost of HF hospitalization remain limited.

Methods

This was a prospective study conducted at Moi Teaching and Referral Hospital. Patients with HF were identified by sequential medical chart abstraction. Primary causes were extracted from echocardiogram reports and adjudicated by a cardiologist. Direct medical cost of hospitalization was derived using activity-based and micro-costing methods, adopting payers' system perspective. Drivers of overall cost were explored using linear regression models.

Results

142 participants were consecutively recruited from September to November 2022. 51.4% were females, and the mean age was 54 (SD 20). The leading primary causes were cor pulmonale (CP), 28.9%; dilated cardiomyopathy (DCM), 26.1%; rheumatic heart disease (RHD), 19.7%; hypertensive heart disease (HHD), 16.9%; ischaemic heart disease (IHD), 6.3%; and pericardial disease (PD), 2.1%. Overall direct cost of HF hospitalization was KES 11,470.94 (SD 8,289.57) [USD 93.49 (67.56)] per patient per day, with the mean length of hospital stay of 10.1 (SD 7.1). RHD incurred the highest costs, KES 15,299.08 (SD 13,196.89) [USD 124.70 (107.56)] per patient per day; IHD, KES 12,966.47 (SD 6656.49) [USD 105.68 (54.25)]; and DCM, KES 12,268.08 (SD 7,816.12) [USD 99.99 (63.71)]. The cost of medications was the leading driver, β = 0.56 (0.55 - 0.56), followed by inpatient fees, β = 0.27 (0.27 - 0.28), and laboratory investigations, β = 0.19 (0.18 - 0.19).

Conclusion

Cor pulmonale, CM, RHD, and HHD were the major causes of HF. The overall direct medical cost of hospitalization was extremely expensive compared with the Kenyan average monthly household income per capita. Widespread comprehensive health insurance coverage is therefore recommended to cushion families against such catastrophic health expenditures besides public health measures aimed at addressing primary causes of HF.

Chronic obstructive pulmonary disease in East Africa: a systematic review and meta-analysis

Chronic obstructive pulmonary disease (COPD) is a common lung disease that causes restricted airflow and breathing problems. Globally, COPD is the third leading cause of death and low- and middle-income countries account for the majority of these deaths. There is limited information on COPD's prevalence in East Africa. Thus the purpose of this systematic review and meta-analysis is to estimate the pooled prevalence of COPD in East Africa.A computerized systematic search using multiple databases was performed in search of relevant English articles from the inception of the databases to August 2023. All the authors independently extracted the data. R and RStudio software were used for statistical analysis. Forest plots and tables were used to represent the data. The statistical heterogeneity was evaluated using I2 statistics. There was heterogeneity between the included articles. Therefore, a meta-analysis of random effects models was used to estimate the overall pooled prevalence of COPD in East Africa. A funnel plot test was used to examine possible publication bias.The database search produced 512 papers. After checking for inclusion and exclusion criteria, 43 full-text observational studies with 68 553 total participants were found suitable for the review. The overall pooled prevalence of COPD in East Africa was 13.322%. The subgroup analysis found the COPD pooled prevalence in the different countries was 18.994%, 7%, 15.745%, 9.032%, 15.026% and 11.266% in Ethiopia, Uganda, Tanzania, Malawi, Sudan, and Kenya, respectively. Additionally, the subgroup analysis of COPD by study setting among community-based studies was 12.132% and 13.575% for hospital-based studies.According to the study's findings, approximately one of every seven individuals in East Africa has COPD, indicating a notably high prevalence of the disease. Thus governments and other stakeholders working on non-communicable disease control should place an emphasis on preventive measures to minimize the burden of COPD.

Chronic respiratory disease in Indigenous peoples: a framework to address inequity and strengthen respiratory health and health care globally

Indigenous peoples around the world bear a disproportionate burden of chronic respiratory diseases, which are associated with increased risks of morbidity and mortality. Despite the imperative to address global inequity, research focused on strengthening respiratory health in Indigenous peoples is lacking, particularly in low-income and middle-income countries. Drivers of the increased rates and severity of chronic respiratory diseases in Indigenous peoples include a high prevalence of risk factors (eg, prematurity, low birthweight, poor nutrition, air pollution, high burden of infections, and poverty) and poor access to appropriate diagnosis and care, which might be linked to colonisation and historical and current systemic racism. Efforts to tackle this disproportionate burden of chronic respiratory diseases must include both global approaches to address contributing factors, including decolonisation of health care and research, and local approaches, co-designed with Indigenous people, to ensure the provision of culturally strengthened care with more equitable prioritisation of resources. Here, we review evidence on the burden of chronic respiratory diseases in Indigenous peoples globally, summarise factors that underlie health disparities between Indigenous and non-Indigenous people, propose a framework of approaches to improve the respiratory health of Indigenous peoples, and outline future directions for clinical care and research.

Non-communicable airway disease and air pollution in three African Countries: Benin, Cameroon and The Gambia

BACKGROUND

Air pollution exposure can increase the risk of development and exacerbation of chronic airway disease (CAD). We set out to assess CAD patients in Benin, Cameroon and The Gambia and to compare their measured exposures to air pollution.

METHODOLOGY

We recruited patients with a diagnosis of CAD from four clinics in the three countries. We collected epidemiological, spirometric and home air pollution data.

RESULTS

Of the 98 adults recruited, 56 were men; the mean age was 51.6 years (standard deviation ±17.5). Most (69%) patients resided in cities and ever smoking was highest in Cameroon (23.0%). Cough, wheeze and shortness of breath were reported across the countries. A diagnosis of asthma was present in 74.0%; 16.3% had chronic obstructive pulmonary disease and 4.1% had chronic bronchitis. Prevalence of airflow obstruction was respectively 77.1%, 54.0% and 64.0% in Benin, Cameroon, and Gambia. Across the sites, 18.0% reported >5 exacerbations. The median home particulate matter less than 2.5 μm in diameter (PM2.5) was respectively 13.0 μg/m3, 5.0 μg/m3 and 4.4 μg/m3. The median home carbon monoxide (CO) exposures were respectively 1.6 parts per million (ppm), 0.3 ppm and 0.4 ppm. Home PM2.5 differed significantly between the three countries (P < 0.001) while home CO did not.

CONCLUSION

Based on these results, preventive programmes should focus on ensuring proper spirometric diagnosis, good disease control and reduction in air pollution exposure.

Understanding the connections between climate change, air pollution, and human health in Africa: Insights from a literature review

Climate change and air pollution are two interconnected global challenges that have profound impacts on human health. In Africa, a continent known for its rich biodiversity and diverse ecosystems, the adverse effects of climate change and air pollution are particularly concerning. This review study examines the implications of air pollution and climate change for human health and well-being in Africa. It explores the intersection of these two factors and their impact on various health outcomes, including cardiovascular disease, respiratory disorders, mental health, and vulnerable populations such as children and the elderly. The study highlights the disproportionate effects of air pollution on vulnerable groups and emphasizes the need for targeted interventions and policies to protect their health. Furthermore, it discusses the role of climate change in exacerbating air pollution and the potential long-term consequences for public health in Africa. The review also addresses the importance of considering temperature and precipitation changes as modifiers of the health effects of air pollution. By synthesizing existing research, this study aims to shed light on complex relationships and highlight the key findings, knowledge gaps, and potential solutions for mitigating the impacts of climate change and air pollution on human health in the region. The insights gained from this review can inform evidence-based policies and interventions to mitigate the adverse effects on human health and promote sustainable development in Africa.

Fungal infections in Sudan: An underestimated health problem

Fungal diseases are associated with high morbidity and mortality, yet their epidemiology and burden are not well addressed. While deaths probably exceed 1.5 million per year, many cases remain undiagnosed and underreported. Estimating the burden of these diseases is needed for prioritization and implementation of effective control programs. Here we used a model based on population at risk to estimate the burden of serious fungal infections in Sudan. The prevalence of the susceptible population including HIV, TB, cancer, asthma, and COPD was obtained from the literature. Incidence and prevalence of fungal infections were calculated using local data when applicable and if not available then regional or international figures were used. In total, the estimated number of Sudanese suffering from fungal disease is 5 M (10% of the total population). Tinea capitis, recurrent vulvovaginitis and keratitis are estimated to affect 4,127,760, 631,261, and 6,552 patients, respectively. HIV-related mycosis is estimated to affect 5,945 oral candidiasis, 1,921 esophageal candidiasis, 571 Pneumocystis pneumonia, and 462 cryptococcal meningitis cases. Aspergillus infections are estimated as follow: 3,438 invasive aspergillosis, 14,950 chronic pulmonary aspergillosis, 67,860 allergic bronchopulmonary aspergillosis cases, while the prevalence of severe asthma with fungal sensitization and fungal rhinosinusitis was 86,860 and 93,600 cases, respectively. The neglected tropical disease eumycetoma was estimated to affect 16,837 cases with a rate of 36/100,000. Serious fungal infections are quite common in Sudan and require urgent attention to improve diagnosis, promote treatment, and develop surveillance programs.

Achieving Universal Health Coverage in Low- and Middle-Income Countries: Challenges for Policy Post-Pandemic and Beyond

Background

Achieving universal health coverage (UHC) is critical for ensuring equity, improving health, and protecting households from financial catastrophe. The COVID-19 pandemic derailed the progress made across primary health targets. This article aims to review the policy challenges to achieve UHC in a post-pandemic world.

Methods

A narrative review of 118 peer reviewed and grey literature was conducted. A total of 77 published articles were identified using an electronic search in PubMed and Scopus and a bibliographic search of relevant literature. Another 41 Reports, websites, blogs, news articles, and data were manually sourced from international agencies (WHO, World Bank, IMF, FAO, etc.), government agencies, and non-government organizations.

Findings

The challenges were identified and discussed under five broad findings: i) weak public health care systems ii) challenges to building resilient health systems, iii) health care financing and financial risk protection, iv) epidemiological and demographic challenges, and v) governance and leadership.

Conclusion

LMICs in Africa and South Asia face significant challenges to achieving UHC by 2030. As countries recover from the pandemic's aftermath, significant investments and innovations are needed to ensure progress toward UHC. Efficient resource mobilization through internal accruals, international cooperation, and resource sharing is needed.
