What is Evidence-Based Nursing?

Evidence-Based Nursing is a form of Evidence-Based Practice, which is defined as the integration of best research evidence with clinical expertise and patient values (Sackett et al. 1996).

Evidence-Based Nursing (EBN) has been defined many ways; Scott and McSherry (2009) reviewed and summarized the literature on EBN to create the following, composite definition: Evidence-based nursing is “an ongoing process by which evidence, nursing theory and the practitioners’ clinical expertise are critically evaluated and considered, in conjunction with patient involvement, to provide delivery of optimum nursing care for the individual” (p 1089). 

Not every action taken by a nurse needs to be an occasion to consult the best evidence of effectiveness, and in some cases, evidence of effectiveness for a particular care plan or practice may not exist. Rather than being a strict formula, EBN is an approach to practice that is intended to improve the safety and effectiveness of nursing care and practices.
