Resumo

CONTEXTO E OBJETIVO: A tomada de decisão em saúde é complexa e deve envolver o profissional de saúde, o paciente e a evidência de melhor nível. A velocidade de geração da informação cria barreiras para manter-se atualizado. Diante disso, metodologistas propuseram um novo tipo de estudo, as overviews de revisões sistemáticas (OoRs). O objetivo é introduzir e demonstrar o papel das OoRs na síntese de informações para profissionais da área da saúde, gestores, pesquisadores e pacientes. TIPO DE ESTUDO E LOCAL: Estudo de série temporal realizado no Centro Cochrane do Brasil, em conjunto com o Programa de Pós-Graduação em Medicina Interna e Terapêutica da Disciplina de Medicina de Urgência e Medicina Baseada em Evidências do Departamento de Medicina da Universidade Federal de São Paulo. MÉTODOS: Para mostrar o crescimento das publicações que fornecem evidência com alto nível e assim justificar a importância das OoRs na síntese e integração das informações, três filtros para desenhos de estudos foram aplicados em duas bases de dados. Uma equação de predição do número esperado de publicações foi desenvolvida e aplicada. RESULTADOS: Na presente década, o número de ensaios clínicos randomizados no Medline poderá chegar a 2.863.203 e o número de revisões sistemáticas poderá chegar a 174.262. Nove OoRs e 15 protocolos de OoRs foram publicados na Biblioteca Cochrane. CONCLUSÕES: Com o crescimento exponencial das publicações, demonstrado neste estudo, um novo tipo de estudo, direcionado especialmente aos decisores em saúde, foi proposto, a OoRs, o qual poderá reduzir incertezas para a tomada de decisão e gerar uma nova hierarquia na pirâmide de evidências.
