BackgroundHeart failure (HF) in pediatric populations is a major public health concern. It is associated with high rates of hospital admissions, disability, and mortality in high-income countries (HIC), but its burden is poorly documented in low- and middle-income countries (LMICs). We present a protocol for a systematic review and meta-analysis to summarize available data on the prevalence, incidence, etiologies, treatment, and outcomes including hospital admission and mortality and economic burden of HF in neonates, infants, children, and adolescents in LMICs.MethodsA comprehensive search of articles published between January 01, 2000, and December 31, 2017, will be performed in PubMed/MEDLINE, EMBASE, Global Index Medicus, and Web of Science. All cross-sectional, cohort studies and case-control studies reporting on the prevalence, incidence, etiologies, treatment, prognosis, admission rates, mortality, and economic burden of HF in pediatric populations in LMICs will be included in the review. The methodological quality of included studies will be appraised accordingly. For prognosis data, the Quality in Prognosis Studies (QUIPS) tool will be used. The symmetry of funnel plot and Egger's test will be used to identify publication bias. An overall summary estimate of prevalence/incidence of pediatric HF across studies will be obtained from study-specific estimates pooled through a random-effect model. Heterogeneity of studies will be assessed by the χ2 test on Cochrane's Q statistic. A p value less than 0.05 will be considered significant for factors that predict mortality. This systematic review and meta-analysis will be reported following the PRISMA guidelines.DiscussionThis study will report and summarize epidemiology data, as well as the economic burden of HF in neonates, infants, children, and adolescents of LMICs. Limitations will mainly arise from the heterogeneity in the diagnostic of HF.Systematic Review RegistrationPROSPERO CRD42017070189.
