[Evidence Based Medicine is] the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients.1
[EBM is] a process of turning clinical problems into questions and then systematically locating, appraising, and using contemporaneous research findings as the basis for clinical decisions.2
