Rheumatic heart disease (RHD) is an important cause of disability and death in low- and middle-income countries. However, evidence-based interventions have not been implemented systematically in many countries. We present a RHD Needs Assessment Tool (NAT) that can be used at country or regional levels to systematically develop and plan comprehensive RHD control programs and to provide baseline data for program monitoring and evaluation. The RHD NAT follows a mixed-methods approach using quantitative and qualitative data collection instruments. Evidence is mapped to a conceptual model that follows a patient through the natural history of RHD. The NAT has 4 phases: 1) situational assessment; 2) facility-based assessment of epidemiology and health system capacity; 3) patient and provider experience of RHD using ethnographic methods; and 4) intervention planning, including stakeholder mapping and development of a monitoring and evaluation framework. The RHD NAT is designed to paint a comprehensive picture of RHD care in an endemic setting and to identify the major gaps to disseminating and implementing evidence-based interventions.
IntroductionCongenital and acquired heart diseases are highly prevalent in developing countries despite limited specialised care. Namibia established a paediatric cardiac service in 2009 with significant human resource and infrastructural constraints. Therefore, patients are referred for cardiac interventions to South Africa.ObjectivesTo describe the diagnoses, clinical characteristics, interventions, post-operative morbidity and mortality, and follow-up of patients referred for care.MethodsDemographics, diagnoses, interventions, intra- and post-operative morbidity and mortality, as well as longitudinal follow-up data of all patients referred to South Africa, were recorded and analysed.ResultsThe total cohort constituted 193 patients of which 179 (93%) had CHD and 7% acquired heart disease. The majority of patients (78.8%) travelled more than 400 km to Windhoek before transfer. There were 28 percutaneous interventions. Palliative and definitive surgery was performed in 27 and 129 patients, respectively. Out of 156 patients, 80 (51.3%) had post-operative complications, of which 15 (9.6%) were a direct complication of surgery. Surgical mortality was 8/156 (5.1%, 95% confidence interval 2.2–9.8), with a 30-day mortality of 3.2%. Prolonged ICU stay was associated with a 5% increased risk of death with hazard ratio 1.05, 95% confidence interval 1.02–1.08, p=0.001. Follow-up was complete in 151 (78%) patients for more than 7 years.ConclusionsDespite the challenges associated with a cardiac programme for referring patients seeking intervention in a neighbouring country and the adverse characteristics of multiple lesions and complexity associated with late presentation, we report good surgical and interventional outcomes. Our goal remains to develop a comprehensive sustainable cardiac service in Namibia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
