Evidence based pharmacy, like evidence based medicine, is a shift from the
traditional paradigm of practice, which was grounded in intuition, clinical experience,
and pathophysiological rational to new paradigm which stresses the importance of
best evidence from clinical research. The evidence based practice requires integrating
individual clinical experience with the best available external clinical evidence and
patient values. The evidence based practice process can be described in five steps: 1)
asking a focused question; 2) acquiring the best evidence by searching the literature; 3)
appraising the literature testing for validity, relevance, and applicability; 4) applying the
results in clinical practice; 5) assessing the outcomes. A set of skills is needed in order
to practice evidence based pharmacy, such as literature searching skills and critical
apprasing skills, but personal attitude and commitment to change could be equally
important
