RESUMO
BACKGROUND: Rheumatic heart disease (RHD) remains endemic in less-resourced regions and countries and results in high medical and non-medical costs to households, health systems, and society. This scoping review maps out the available evidence on the economic impact of RHD and its antecedents and suggests future research priorities. METHOD: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. We identified articles through systematic electronic database search supplemented by expert knowledge of unpublished literature. Studies were included if they collected empirical RHD-related costing data as a primary or secondary objective and if the data were collected from 2000 onward. Main quantitative findings by intervention, costing perspective, and location were charted, and a standardized quality assessment tool was used to appraise included studies. RESULTS: The index search identified 2519 electronic records and two grey-literature graduate theses. Six full texts were included in the review. Primary prevention costs were modest, while secondary and especially tertiary prevention were more costly. Most estimates were of health sector costs and for tertiary interventions. Only two studies described RHD-related costs in non-high-income countries. Most studies were of adequate methodological quality. CONCLUSION: Research into the costs of RHD has mostly been done in wealthy countries. Costs from the household perspective, which are particularly important in countries with limited public healthcare finance, are lacking. To inform advocacy and guide implementation of the 2018 World Health Assembly resolution on RHD, high-quality, local cost estimates will be needed from a range of representative, RHD-endemic countries.
