Delivering effective, comprehensive, multi-exercise component cardiac rehabilitation (CR) for chronic heart failure patients in low resource settings in sub-Saharan Africa: Queen Elizabeth Central Hospital-(QECH-CR) randomised CR study, Malawi.

BACKGROUND: The delivery of Cardiac Rehabilitation (CR) and attaining evidence-based treatment goals are challenging in developing countries, such as Malawi. The aims of this study were to (i) assess the effects of exercise training/ CR programme on cardiorespiratory and functional capacity of patients with chronic heart failure (CHF), and (ii) examine the effectiveness of a novel, hybrid CR delivery using integrated supervised hospital- and home-based caregiver approaches. METHODS: A pre-registered (UMIN000045380), randomised controlled trial of CR exercise therapy in patients with CHF was conducted between September 2021 and May 2022. Sixty CHF participants were randomly assigned into a parallel design-exercise therapy (ET) (n = 30) or standard of care (n = 30) groups. Resting hemodynamics, oxygen saturation, distance walked in six-minutes (6MWD) and estimated peak oxygen consumption (VO2 peak) constituted the outcome measures. The exercise group received supervised, group, circuit-based ET once weekly within the hospital setting and prescribed home-based exercise twice weekly for 12 weeks. Participants in both arms received a group-based, health behaviour change targeted education (usual care) at baseline, 8-, 12- and 16-weeks. RESULTS: Most of the participants were female (57%) with a mean age of 51.9 ±15.7 years. Sixty-five percent (65%) were in New York Heart Association class III, mostly with preserved left ventricular ejection fraction (HFpEF) (mean Left Ventricular Ejection Fraction 52.9 ±10.6%). The 12-weeks ET led to significant reductions in resting haemodynamic measures (all P <0.05). The ET showed significantly higher improvements in the 6MWD (103.6 versus 13.9 m, p<0.001) and VO2 peak (3.0 versus 0.4 ml·kg-1·min-1, p <0.001). Significant improvements in 6MWD and VO2 peak (both p<0.001), in favour of ET, were also observed across all follow-up timepoints. CONCLUSION: This novel, randomised, hybrid ET-based CR, delivered to mainly HFpEF patients using an integrated hospital- and home-based approach effectively improved exercise tolerance, cardiorespiratory fitness capacities and reduced perceived exertion in a resource-limited setting.

Quality of life of primary caregivers of children living with cerebral palsy at two clinics in Blantyre, Malawi.

Introduction: In Malawi, Primary Caregivers (PCGs) of children living with Cerebral Palsy report challenges such as physical strain and lack of resources that affect care giving. Although such experiences affect the PCGs' Quality of Life (QoL), there is paucity of data for Malawi. Understanding their QoL would inform establishment of holistic intervention(s) tailored to meet their needs. Therefore, the purposes of this study were to determine QoL of PCGs of the children who were receiving rehabilitation at Queen Elizabeth Central Hospital (QECH) and Feed the Children (FtC), to identify PCG's and children's socio-demographic factors that may attribute to the perceived QoL, and to compare the PCGs' QoL between the sites. Methods: A cross-sectional study was conducted from January to April 2019 on 142 PCGs of children aged between 2 and 18 years of age. All PCGs who were employed for the child-care, or had a chronic sickness were excluded. QoL was assessed using the World Health Organization Brief questionnaire, with a cut-off point of <60% for poor QoL. The severity of children's impairments was assessed using Gross Motor Function Classification System. Descriptive and inferential statistics were conducted to analyze the data. The PCGs' age, sex, marital status and level of education, and child's severity of impairment were compared with QoL. Results: The majority of PCGs (61.30%) had poor QoL, and there was no significant difference in overall QoL of the PCGs between the sites (p<0.31). The PCGs at QECH had significantly higher physical domain mean scores than at FtC (U=1906, p<0.01). The overall QoL differed significantly across the marital statuses of the PCGs (p<0.03). Conclusion: The study has established that most PCGs at both sites possess poor QoL. However, there is need to investigate how the rehabilitation institutions and workers influence the QoL of the PCGs within and between the facilities.

Effects of cardiac rehabilitation treatment modalities in Sub-Saharan Africa: A systematic review.

Purpose: Although Cardiac Rehabilitation (CR) implementation models recommend delivery of any CR treatment component, Sub-Saharan Africa (SSA) constitutes only 17% of globally available CR programs. The aims of this review were to assess the benefits of employing any CR treatment modality in SSA, and evaluate if this approach should be encouraged in this resource-constrained region. Methodology: Records were identified electronically via CINAHL, MEDLINE, Cochrane library, African journal online, PubMed, Web of science and google scholar, and grey literature was hand-searched. Articles reporting effectiveness of any CR treatment modality were included if participants had any cardiovascular disease and if the study was conducted in SSA. Quality assessment for each enrolled study was done using Downs and Black (1998) checklist and data was extracted using a modified standard tool. Results: Searches identified 1666 records, 24 full text articles were examined and 10 were included for the review; 60%, 30% and 10% of the enrolled studies were done in South Africa, Nigeria and Benin respectively. The studies implemented exercise, psychosocial and education treatment modalities of CR, and the approach of delivery was either comprehensive or modified. Comprehensive CR and delivery of combined aerobic and resistance exercises improved physical (13%, p=0.001), social (40%, p=0.001) and mental aspects of quality of life and reduced anxiety (-12%, p<0.05) and depression (-6%, p<0.001) respectively. Comprehensive CR and aerobic training both reduced systolic blood pressure (range of mean reduction [RMR] -6 to -14mmHg), diastolic blood pressure (RMR -4 to -6mmHg) and resting heart rate (RMR -7 to -17bpm). Overall, all types of exercises showed a 1-5ml.kg-1.min-1 increase in peak oxygen consumption. Conclusion: The findings support delivery of exercise treatment modality and comprehensive delivery of CR in SSA. However, efficacy of independent implementation of education and psychosocial therapeutic components of CR remains unclear; hence the need for further investigations.
