Fundamentals and Method of Systematic Reviews
Fundamentos y Método de las Revisiones Sistemáticas
Main Article Content
Systematic reviews (SR) are qualitative and, sometimes, quantitative syntheses on the available evidence regarding a specific topic. This work contextualizes its origin in the evidence-based medicine movement and defines it as a type of health research aimed to identify, critically appraise and synthesize previous scientific knowledge. The SR method is presented here in a series of steps: objective, search and selection of studies, quality assessment, data extraction and analysis, meta-analysis and interpretation of results. The internal validity, precision and external validity of the results are explained as criteria to assess the quality of the evidence. The quality of the evidence, together with the quantity and consistency, are the basis on which recommendations can be made. The SR method is useful in professional practice, where the management of up-to-date scientific evidence is required to make decisions on diagnoses or interventions daily, as well as a type of research that can be implemented in undergraduate or graduate studies, since it could arrive at original results by synthesizing the previous knowledge.
