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.
The Limitations of Evidence-Based Practice Evidence-based practice does have limitations. One of the limitations alluded to above is its focus on the treatment of groups rather than individuals. Therefore, the evidence provides guidelines as to how patients, as a group, should be treated and in that way also provides some guidance as to how the individual patient should be treated.
