RESUMO
Os ensaios clínicos controlados e randomizados (ECCR) são considerados o padrão ouro da medicina baseada em evidências na atualidade, sendo importantes para direcionar a conduta médica através de observações científicas consistentes. Passos como seleção dos pacientes, randomização e cegamento são fundamentais na realização de um ECCR e apresentam algumas dificuldades extras nos ensaios que envolvem procedimentos cirúrgicos, como é comum na Ortopedia. O objetivo deste artigo é destacar e discutir algumas dificuldades e eventuais limitações dos ECCR na área cirúrgica.
ABSTRACT
Randomized controlled clinical trials (RCTs) are considered to be the gold standard for evidence-based medicine nowadays, and are important for directing medical practice through consistent scientific observations. Steps such as patient selection, randomization and blinding are fundamental for conducting an RCT, but some additional difficulties are presented in trials that involve surgical procedures, as in common in orthopedics. The aim of this article was to highlight and discuss some difficulties and possible limitations on RCTs within the field of surgery.
