Evidence-based surgery is an exciting project is underway that serves SOURCE’s goals to increase awareness of the importance of evidence-based surgery among surgeons and to increase the dissemination of surgical outcomes research findings. This is the evidence-based series of surgery.
Fortunately, evidence-based medicine in surgery has now been thoroughly accepted; sophisticated researchers are applying a variety of study designs and methodological techniques to answer an expansive number of important clinical questions. Nonetheless, despite the diversity of high-quality research being performed, many continue to contend that the randomized controlled trial is the only valid source of evidence, whereas observational research is assumed to be only preliminary work. The need and legitimacy of both experimental and observational studies deserve to be highlighted.
