EBP is the integration, by clinicians, of clinical expertise which is meticulous, explicit and uses current clinically appraised professional knowledge (Eizenberg, 2011; Kenny, Richard, Ceniceros, & Blaize, 2010). EBP accommodates patient preferences, views and values; while also guiding, supporting, validating and answering health care workers clinical judgements, practices, and questions (Eizenberg, 2011; Kenny et al., 2010; Matula, 2005; Wolf, 2005). EBP is a process of asking a clinical question; searching for clinical evidence; critically appraising this evidence and then expertly integrating this evidence with patient’s values, views and preferences; evaluation of how the changes to practice have had on outcomes; and finally disseminating the results that the EBP or change had on patient outcomes (Melnyk, Fineout-Overholt, Stillwell, & Williamson, 2010).
The definition of EBP and EBNP and the implementation of EBNP appear to be straightforward and easily accomplished; however, EBNP implementation is far removed from being easy (Brim & Schoonover, 2009; Cullen, Titler, & Rempel, 2011; Eizenberg, 2011; Kenny et al., 2010; Tolson, Booth, & Lowndes, 2008). Nursing research has uncovered numerous challenges and barriers which the implementation of EBNP faces. These challenges and barriers can be classified
