According to Mosby's Dictionary of Medicine, Nursing and Health Professions:
Evidence-based practice is "the practice of health care in which the practitioner systematically finds, appraises, and uses the most current and valid research findings as the basis for clinical decisions".
In order to promote the principles, teaching and implementation of evidence-based practice, a consensus statement was agreed by delegates at the second international conference of Evidence-Based Healthcare Teachers and Developers held in Sicily in September 2003. The group agreed that evidence-based practice (EBP) requires that decisions about healthcare are based on the best available, current, valid and relevant evidence. These decisions should be made by those receiving care, informed by the tacit and explicit knowledge of those providing care, within the context of available resources (Margaret Edwards, Key Concepts in Nursing, 2012).
EBP ranks the quality of evidence by levels as seen in the image to the right. As you move from Level VII at the bottom to Level I at the top, the quality of the evidence increases. For more information on the different Levels of Evidence, see the image to the right and the link below.
