Barriers that might hold nursing practice from achieving 90% of   practice be evidence-based by 2020 include priority and education   towards the practice itself.

Barriers that might hold nursing practice from achieving 90% of   practice be evidence-based by 2020 include priority and education   towards the practice itself.    A research done by a   group in Columbus, Ohio surveyed 276 chief nurse executives to see how   evidence based practice rank in their institutions.  The studies   states that even though it is known that evidence based practice has   resulted in high quality care and improve population health as well as   showing better patient experience and lowering costs it is not a   priority in most institutions.    (Nurse.com)

The priority focus in most institution that are not practicing   evidence-base practice is not evidence-based practice but other issues   such as quality of care and safety.  The mind set is that as soon   as they have a handle on quality of care and safety then the next   issue will be evidence-based practice.  I think institutions are   thinking that to compile evidence on issues and compare them is too   time consuming so they rather to focus on other issues. An example   used in the article is that Emergency Department continue to treat   children that present with asthma with nebulizers when there are   numerous studies that show that the outcome is better when a metered   bronchodilator is used.  “when patient get, evidence based   care, they have 28% better outcome.  (nurse.com)

Most of the chief nurses that were in the survey was unsure of how   to measure patient outcome.  This is where education comes   in.  Nurses are graduating with doctoral degrees.  There   curriculum needs to emphasize the importance of evidence-base practice   and how its use can facilitate better outcome.  In this way when   these nurses are practicing they will be more inclined to rely on   evidence-base practice.
