Evidence-Based Medicine (EBM) as a subset of Evidence-Based Practice (EBP) is the "conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients" (Sackett, et al.). Using available evidence, or "grounds for belief" in the form of "facts or observations adduced in support of a conclusion" (OED), EBM takes into consideration available research in the biomedical sciences in conjunction with the clinical expertise of medical professionals alongside patient values and preferences.

EBM has come to be accepted as the most effective method of using available biomedical knowledge in the everyday practice of medicine. With rapid changes in medical knowledge and practice, understanding how to effectively integrate research and practice makes it easier to find, appraise, and apply evidence during busy clinical schedules. It further supports the ongoing research efforts of physicians and medical professionals whose career relies on continued scholarship.
Put in another way, "EBM requires clinicians to understand how uncertainty about clinical research evidence intersects with an individual patient's predicament and preferences" (Guyatt, et al.) This is further underscored in the three fundamental principles of EBM:
1) Awareness of the evidence on which one's practice is based.
2) Guidance and discernment to decide whether evidence is valid and reliable
3) Ability to further determine the risks, burden, and costs associated with standard or alternative management strategies alongside the consideration of patient values and preferences
