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).
基于证据的实践（EBP）概述
以证据为基础的实践（EBP）是从长期的循证医学证据，出现了几种方法来确定最佳做法是使用科学证据。在长期的移动的原因是科学的重要性的认识的证据被许多临床医生不仅医生在临床决策过程。循证实践是为了更大的重视，提高健康水平，可以提供给患者（fineoutoverholt，E，等。，2005）。萨克特DL，罗森伯格等人，（1996）和森林（2002）描述了JL EBP作为当前的最佳证据，最精确的集成的临床研究，和决策过程中对病人的健康价值观。然而，比德韦尔Sr（2004）和jettle杜等人。（2003）已确定这种集成到病人的价值认识不足作为实施和被许多临床医生的证据基础实践适应的最大障碍。
为了更好地了解EBP方法，重要的是要知道如何这种方法涉及到的护理，有利于实践。麦克尤恩（2002）提出了仪式，隔离和杂乱无章的临床经验，可在循证实践强调护理可以联合国地不同的见解和研究传统。护理专业是公认的，视为一个有纪律实践的社会认可（Estabrooks，1998）。他进一步得出结论，在他的研究中说，在护理实践基础的证据，包括各种形式的实践知识，因此它不仅仅是利用研究。换句话说，循证护理被公认为一门学科，目前的研究证据和临床指南的批准，政策，适应的护理使患者的最佳值的临床决策（ciliska，pineli等人，2001；2002，克罗夫特欧文，马隆等人。，2004）。
