Resumo

Introdução: O sistema de graduação de qualidade de evidência e força de recomendação, denominado Grading of Recommendations, Assessment, Development and Evaluation (GRADE), tem sido adotado por organizações para o desenvolvimento de diretrizes e por revisores sistemáticos para análise da qualidade da evidência. Esse artigo tem como objetivo descrever os princí­pios e a abordagem do sistema GRADE. Método: Revisão de literatura utilizando as bases de dados Medline, CINAHL e Web of Science. Resultados: O sistema classifica a qualidade da evidência em alta, moderada, baixa e muito baixa, de acordo com fatores que consideram: a metodologia dos estudos, a consistência e a precisão dos resultados, o direcionamento da evidência e o viés de publicação. A força da recomendação é graduada em forte ou fraca e baseia-se não apenas na qualidade da evidência, mas no equilí­brio entre benefí­cio e malefí­cio da intervenção, valores e preferências do paciente e utilização dos recursos e custos. Os achados apresentados por esse sistema refletem a extensão da confiabilidade de que as estimativas dos efeitos encontradas estão corretas. Conclusão: O entendimento do sistema GRADE facilita a interpretação crí­tica de revisões sistemáticas e diretrizes que o utilizam e espera-se que haja um aumento da sua incorporação na produção desses estudos na área da fisioterapia.

Palavras-chave: prática clí­nica baseada em evidências, revisão, guia de prática clí­nica.
