The document discusses evidence-based medicine and sources for clinicians to find high-quality evidence. It defines evidence-based medicine as integrating the best available research evidence, clinical expertise, and patient values. Randomized controlled trials are considered the gold standard for assessing new interventions. The document recommends searching multiple sources of varying methodological rigor, from the Cochrane Library which systematically reviews randomized trials, to UpToDate, Clinical Evidence, evidence-based guidelines, and PubMed. The key is finding the best evidence available to answer clinical questions and apply results to patients.
