"Evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients" - Sackett et al.
It is is a process which combines the individual doctor's expertise, the best available external clinical evidence and the patient's preferences when making decisions about the patient's health care.
