3. What is evidence-based medicine? Evidence-based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.
The practice of evidence-based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research.
Sackett DL et al. Evidence based medicine: what it is and what it isn't. BMJ 1996 Jan 13; 312 (7023): 71-2. 3 Evidence-based practice uses the results of scientific studies whenever possible and expert opinion and extensive experience when data are lacking.
Evidence-based practice uses the results of scientific studies whenever possible and expert opinion and extensive experience when data are lacking.
4. Evidence-Based Medicine 4
5. What makes good evidence? Based on scientific research
RCT
Systematic review
Meta-analysis
Clinical guidelines Expert opinion
Consensus
Because its been done this way for 100 years 5 What info qualifies as evidence-based?
Evidence-based sources contain information that has been consistently and systematically identified, evaluated, selected and synthesized.
Based on solid scientific research
Synthesized to increase the validity of the conclusions
What is not evidence?
A journal article about one study an RCT or a case study isnt necessarily evidence on its own.
However, that article can be added to a number of other articles investigating the same question and included in a synthesis of the research.
That evaluation and synthesis is the key to what informs evidence-based summary resources.

6. EBP Implications for Nursing Are U.S. nurses ready for evidence-based practice?
Many dont understand or value research
Many have little of no training to help find evidence on which to base their practice
Pravikoff DS, Tanner AB, Pierce ST. Readiness of U.S. nurses for evidence-based practice. American Journal of Nursing 2005 Sep;105(9):
40-52.
Failure to use evidence results in lower quality, less effective and more expensive care.
Berwick DM. Disseminating innovations in health care. JAMA 2003 Apr 16;289(15):1969-75. 6 Are nurses ready for evidence-based practice?
Results in better pt outcomes
Barriers to nurses using EBP:
-Lack of time
-Lack of value of research in practice
-Lack of understanding of electronic databases
-Lack of computer skills
-Difficulty understanding research articles
