EBM is "the conscientious use of current best evidence in making clinical decisions about patient care". This original definition is attributed to this article by Sackett, et al.

EBP is a method of effectively translating EBM into clinical practice using the best existing evidence and research, knowledge of clinical experts, and patient preferences.

Nurses conduct Evidence-Based research to support Evidence-Based Practice. Nurses use EMP because nurses want the best outcomes for their patients. 

The Focus = finding evidence of the best methods, interventions and practices
The Evidence = found in the most current professional research literature
The Goal = best outcomes for the patient
