There are many barriers to promoting evidence based practice. The first of which would be the practitioner's ability to critically appraise research. This includes having a considerable amount of research evaluation skills, access to journals, and clinic/hospital support to spend time on EBN.
Evidence based practice seeks to replace practice as usual, with practice guided by rigorous outcome-oriented research, ideally randomized controlled trials. It also seeks to make practice a less subjective enterprise, and to raise it to a higher level of accountability. It is associated with efforts to identify best practices in nursing and other disciplines. The limitations of evidence-based practice for nursing are not routinely discussed or considered by many clinicians. In this article the author raises several critical questions about the use of evidence-based practice in nursing.
