EBM is the acronym for "Evidence Based Medicine". The British Medical Journal defines EBM as "the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research."

The following links provide additional information and explanation of EBM:
