RESUMO
About a quarter of a century after the introduction of the concept and principles of evidence-based medicine (EbM), some healthcare providers are still adamant that these are incompatible with knowledge gained through experience. Across the surgical disciplines, it is often argued EbM underestimates or neglects the importance of intuition and surgical skills. To put it bluntly, these assumptions are wrong and often characterized by a misunderstanding of the methodology of EbM. Even the best controlled trial cannot be properly interpreted or implemented without clinical reasoning; furthermore, clinicians of all disciplines are obligated to provide care according to the current state of scientific knowledge. In an era of revolutionary biomedical developments, exponential increase of research but incremental innovations, they must become familiar with pragmatic tools to appraise the validity and relevance of clinical study results, and to decide whether there is a need to adapt current beliefs and practices based on the new information. We herein use the recent example of a new medical device for the surgical treatment of rotator cuff tears and subacromial impingement syndrome to illustrate how important it is to interpret data in the context of a precise, answerable question and to combine clinical expertise with methodological principles offered by EbM.
