Utilisation of mobile phone interventions to improve the delivery of maternal health services in sub-Saharan Africa: A scoping review protocol

INTRODUCTION

There has been significant progress in maternal health outcomes in the sub-Saharan African region since the early 1990s, in part due to digital and mobile health interventions. However, critical gaps and disparities remain. Mobile phones in particular have potential to reach underserved, hard-to-reach populations with underdeveloped infrastructure. In spite of the opportunities for mobile phones to address maternal mortality in the region, there is no extensive mapping of the available literature on mobile phone interventions that aim to improve access of maternal care in sub-Saharan Africa. The proposed scoping review aims to map literature on the nature and extent of mobile phones interventions designed to improve maternal care health services in the region.

METHODS

Conduct of this scoping review will be guided by the Joanna Briggs Institute approach. Literature searches will be conducted in multiple electronic databases, including MEDLINE, Embase, CINAHL, APA PsycInfo, Cochrane Central Register of Controlled Trials, Global Health, African Index Medicus, Web of Science, and Applied Social Sciences Index & Abstracts. Grey literature will also be identified. Keyword searches will be used to identify articles. Two reviewers will independently screen eligible titles, abstracts and full articles with a third reviewer to help resolve any disputes. We will extract data on general study characteristics, population characteristics, concept, context, intervention details, study results, gaps and recommendations.

DISCUSSION

Understanding use of mobile phones among underserved, hard-to-reach populations with underdeveloped infrastructure to address maternal mortality in developing countries is very critical to informing health systems on potential effective strategies. This review will complement the evidence base on utilisation of mobile phone interventions to improve the delivery of maternal health services in sub-Saharan Africa.

A case report of Trichinella spiralis pericarditis: an unusual cause of pericardial effusion and cardiac tamponade in an immunocompetent urban black African

Background

Cardiac trichinellosis is unusual and it is associated with high mortality. We report a case of Trichinella pericarditis complicated by a large pericardial effusion and cardiac tamponade in a setting where the aetiologic diagnosis of pericardial disease is challenging.

Case summary

A 27-year-old immune-competent male patient from Cameroon consulted for pleuritic chest pain associated with fever, dry cough, and gradually worsening dyspnoea on exertion of 1-month duration. Upon admission, his blood pressure was 100/73 mmHg, the heart rate was 130/min. The clinical examination revealed a pericardial friction rub, jugular venous distension, and tender hepatomegaly. There was no lower extremity oedema. The diagnosis of pericarditis was made. A two-dimensional transthoracic echocardiogram performed showed a moderate fibrinous circumferential pericardial effusion with echocardiographic signs of tamponade. Pericardiocentesis was performed and analysis of the fluid revealed multiple, motile, roundworms which were identified as Trichinella spiralis, a nematode parasite. There was no eosinophilia on complete blood count. He was treated with Albendazole 800 mg daily per os. His clinical condition improved with resolution of the symptoms and a reduction in the size of the pericardial effusion.

Discussion

Trichinella spiralis is a rare cause of pericarditis which can be life-threatening. With the existing challenges in diagnosing the aetiology of pericardial disease in African resource-limited setting, the diagnosis can be missed leading to fatal outcomes.

Prevalence, correlates and in-hospital outcomes of kidney dysfunction in hospitalized patients with heart failure in Buea-Cameroon

Background

Kidney dysfunction is common in patients with heart failure (HF) and has been associated with poor outcomes. This study aimed to determine the prevalence, correlates, and prognosis of kidney dysfunction in patients with HF in Cameroon, an understudied population.

Methods

We conducted a cross-sectional study in consecutive patients hospitalized with HF between June 2016 and November 2017 in the Buea Regional Hospital, Cameroon. Kidney dysfunction was defined as an estimated glomerular filtration rate < 60 ml/min/1.73m². Prognostic outcomes included death and prolonged hospital stay (> 7 days). We also performed a sensitivity analysis excluding racial considerations.

Results

Seventy four patients (86.1% of those eligible) were included. Their median age was 60 (interquartile range: 44–72) years and 46.0% (n = 34) were males. Half of patients (n = 37) had kidney dysfunction. Correlates of kidney dysfunction included previous diagnosis of HF (adjusted odds ratio [aOR]4.3, 95% CI: 1.1–17.5) and left ventricular hypertrophy (aOR3.4, 95% CI: 1.1–9.9). Thirty-six (48.9%) had prolonged hospital stay, and seven (9.5%) patients died in hospital. Kidney dysfunction was not associated with in-hospital death (aOR 0.4, 95% CI: 0.1–2) nor prolonged hospital stay (aOR 2.04, 0.8–5.3). In sensitivity analysis (excluding racial consideration), factors associated with Kidney dysfunction in HF were; anemia (aOR: 3.0, 95% CI: 1.1–8.5), chronic heart failure (aOR: 4.7, 95% CI: 0.9–24.6), heart rate on admission < 90 bpm (aOR: 3.4, 95% CI: 1.1–9.1), left atrial dilation (aOR: 3.2, 95% CI: 1.04–10), and hypertensive heart disease (aOR: 3.1, 95% CI: 1.2–8.4). Kidney dysfunction in HF was associated with hospital stay > 7 days (OR: 2.6, 95% CI: 1–6.8).

Conclusion

Moderate-to-severe kidney dysfunction was seen in half of the patients hospitalized with HF in our setting, and this was associated with a previous diagnosis of HF and left ventricular hypertrophy. Kidney dysfunction might not be the main driver of poor HF outcomes in this population. In sensitivity analysis, this was associated with anemia, chronic heart failure, heart rate on admission less than 90 bpm, left atrial dilatation, and hypertensive heart disease. Kidney dysfunction was associated with hospital stay > 7 days.

Scoping review protocol to understand the conceptualisation, implementation and practices of health promotion within the context of primary healthcare in Africa

INTRODUCTION

The ongoing COVID-19 pandemic has highlighted the importance of health promotion in empowering and sustaining communities, as well as the need to build resilient health systems and work collectively with other sectors to protect and promote health. The WHO has mainstreamed health promotion in the Global health agenda. However, the definition and practices of health promotion in Africa are not well understood and documented, with often, an interchangeable use of the concept of health promotion and health prevention. This scoping review is to explore how health promotion is defined and practised in Africa and identify gaps in its implementation within the framework of the Ottawa Charter.

METHODS AND ANALYSIS

The scoping review will employ the approach described by Arksey and O'Malley in 2005. The approach consists of five stages: (1) formulating the research questions, (2) identifying relevant studies, (3) selecting eligible studies, (4) charting the data and (5) collating, summarising and reporting the results. This protocol employed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P). The review will apply the PRISMA extension for scoping reviews to present the results. The scoping review will adapt the five principles set forth in the Ottawa Charter to categorise the outcomes and uses its strategies to define the interventions. Data bases searched are Ovid Medline, Embase, Cochrane Library, CINAHL, SCOPUS, CABI, JBI Evidence Synthesis and grey literature. The database last searched was January 2021.

ETHICS AND DISSEMINATION

This review does not require ethics approval. Our dissemination strategy includes peer review publication, policy brief, presentation at conferences and relevant stakeholders.
