ABSTRACT
BACKGROUND: Globally, rheumatic heart disease (RHD) is a major contributor to the burden of cardiovascular disease. Major gaps in RHD prevention and treatment have been documented at all levels of health systems in low- and middle-income countries. Task sharing is an approach that could prove effective in remediating bottlenecks in RHD-related care. OBJECTIVES: This study conducted a systematic review to assess the state of the evidence for the use of task sharing in the diagnosis, prevention, and management of RHD. METHODS: Guided by a previously published protocol, we searched various databases using a systematic search strategy including MeSH and free-text terms for (1) group A streptococcus, acute rheumatic fever, and RHD and (2) strategies of task sharing in limited-resource settings. Two investigators independently screened the search outputs, selected the studies, extracted the data, and assessed the risk of bias, resolving discrepancies by discussion and consensus. RESULTS: The publications search yielded 212 records, of which 18 articles were deemed as potentially eligible for inclusion. None of the studies, however, met with the inclusion criteria. CONCLUSIONS: There is a lack of evidence for the use of task-sharing approaches in scaling up RHD prevention and treatment services in limited-resource settings. Considering the persistent burden of group A streptococcus, acute rheumatic fever, and RHD in low- and middle-income countries, this work highlights the urgent need to develop and test models of RHD-related care utilizing an evidence-based approach to task sharing.
