Overview of Evidence Based Practice (EBP)
Evidence Based Practice (EBP) was shifted from the term evidence based medicine that was emerged to exemplify several approaches to determine best practices using scientific evidences. Reason behind the shift in the term was the recognition of the importance of scientific evidences by many clinicians not only physicians in various clinical decision making process. Evidence based practice was given greater emphasis in order to improve the health level that can be offered to patients (Fineoutoverholt, E, et al., 2005). Sackett DL, Rosenberg et al, (1996) and Forest JL (2002) has described EBP as most accurate integration of current best evidence, clinical research, and decision making process concerning about the health values of the patients. However, Bidwell SR (2004) and Jettle DU et al. (2003) has identified the lack of knowledge of such integration into patient values as one of the greatest barriers for implementation and adaption of evidence based practices by many clinicians.
In order to have better understanding of EBP approach, it is important to know how this approach is related to nursing and how it is beneficial for practice. McEwen (2002) has suggested that ritual, isolated and unsystematic clinical experiences can be de-emphasized by evidence based practice in nursing and it can un-ground the different opinions and research traditions. Nursing profession was acknowledged and considered as a disciplined practice sanctioned by the people in the society (Estabrooks, 1998). He further concluded in his research that evidence based practice in nursing consist various forms of practice knowledge and thus it is more than just using the research. In other words, evidence based nursing was acknowledged as a discipline where current research evidences approved, by clinical policies and guidelines, are adapted by nurses to make clinical decision in the best value of the patients (Ciliska, Pineli et.al, 2001; Ervin, 2002 and Rycroft-Malone et al., 2004).
