Cardiac rehabilitation delivery in Africa

Unmet Needs for Cardiac Rehabilitation in Africa: A Perennial Gap in the Management of Individuals with Cardiac Diseases

Cardiac rehabilitation (CR) is a standard model of care, and an established component of comprehensive care that has been proven to reduce mortality and morbidity in patients with cardiac diseases. International clinical practice guidelines routinely recommend that cardiac patients participate in CR programs for comprehensive secondary prevention. However, there is scant guidance on how to deliver these programs in low-resourced settings. This dearth of clinical practice guidelines may be an indication of low emphasis placed on CR as a component of cardiac health services in low-income countries, especially in Africa. Indeed, CR programs are almost non-existent in Africa despite the unmet need for CR in patients with ischemic heart disease in Africa reported to be about one million. This figure represents the highest unmet need of any World Health Organization region, and is colossal given the projected accelerated increases in incidence of cardiovascular diseases (CVD) in the region. This narrative review explored the availability of CR programs, potential barriers to CR and strategies that can mitigate such barriers in Africa.

Exercise-based rehabilitation for major non-communicable diseases in low-resource settings: a scoping review

INTRODUCTION

While there is substantial evidence for the benefits of exercise-based rehabilitation in the prevention and management of non-communicable disease (NCD) in high-resource settings, it is not evident that these programmes can be effectively implemented in a low-resource setting (LRS). Correspondingly, it is unclear if similar benefits can be obtained. The objective of this scoping review was to summarise existing studies evaluating exercise-based rehabilitation, rehabilitation intervention characteristics and outcomes conducted in an LRS for patients with one (or more) of the major NCDs.

METHODS

The following databases were searched from inception until October 2018: PubMed/Medline, Embase, CINAHL, Cochrane Library, PsycINFO and trial registries. Studies on exercise-based rehabilitation for patients with cardiovascular disease, diabetes, cancer or chronic respiratory disease conducted in an LRS were included. Data were extracted with respect to study design (eg, type, patient sample, context), rehabilitation characteristics (eg, delivery model, programme adaptations) and included outcome measures.

RESULTS

The search yielded 5930 unique citations of which 60 unique studies were included. Study populations included patients with cardiovascular disease (48.3%), diabetes (28.3%), respiratory disease (21.7%) and cancer (1.7%). Adaptations included transition to predominant patient-driven home-based rehabilitation, training of non-conventional health workers, integration of rehabilitation in community health centres, or triage based on contextual or patient factors. Uptake of adapted rehabilitation models was 54%, retention 78% and adherence 89%. The majority of the outcome measures included were related to body function (65.7%).

CONCLUSIONS

The scope of evidence suggests that adapted exercise-based rehabilitation programmes can be implemented in LRS. However, this scope of evidence originated largely from lower middle-income, urban settings and has mostly been conducted in an academic context which may hamper extrapolation of evidence to other LRS. Cost-benefits, impact on activity limitations and participation restrictions, and subsequent mortality and morbidity are grossly understudied.
