AbstractThe Cochrane Collaboration provides growing and readily accessible resources to help ensure that medical decision-making is based on detailed, methodical, and up-to-date reviews of the best available evidence. We analyzed systematic reviews in the field of pediatric cardiology published by the Cochrane Collaboration's 50 Collaborative Review Groups. We found a total of 20 systematic reviews: 13 published by the Cochrane Neonatal Group, 6 by the Cochrane Heart Group, and 1 by the Cochrane Peripheral Vascular Disease Group. Systematic reviews in pediatric cardiology appear infrequently. They only concern evidence-based decision-making in the therapeutic management of patent ductus arteriosus and arterial hypotension in preterm infants, and in the management of children with Kawasaki disease. The quality of the clinical trials contained in the systematic reviews of acute rheumatic fever or obesity in children is limited. Consequently, the reviewers' conclusions provide an inadequate basis for inferring probable effects in clinical practice. In pediatric cardiology, many therapies continue to be used without supportive evidence. We found no systematic reviews of important cardiologic topics in childhood such as heart failure, shock, hypertension, congenital cardiopathy, and arrhythmia. Clinical practice guidelines complement systematic reviews, which can recommend only strategies that are supported by strong evidence or suggest further research when scientific evidence is inadequate.
