•"Doing the right things right" (Craig & Smyth, 2002, p.4) •Used to improve the experiences associated with health care and illness •Early examples
oInfection control (aseptic technique)
oDVT (deep vein thrombosis) prevention

Development of the EBP Concept
•Began with medicine
oArchie Cochran, a British epidemiologist in 1972 published a book criticizing the medical profession for not reviewing medical research studies oBelieved that the strongest evidence came from RCT (randomized clinical trials). RCT are the most strict kind of research design. •A RCT has to have three things:

•Control group
•Placebo group
•Experimental group
oFounded the Cochran Foundation in 1992 after his death
•Defined as "the conscientious, explicit and judicious use of current best evidence in making decisions about the health care of patients" (Sackett, et al) •Focused on findings of randomized clinical trials only

•New definition: "the integration of best research evidence with clinical expertise and patient values (Sackett, et. al.)

Current Definition in Nursing
•"Evidence-based practice (EBP) is a problem solving approach to clinical practice that integrates the conscientious use of best evidence in combination with a clinician's expertise as well as patient preferences and values to make decisions about the type of care that is provided" (Melnyk, 2004)

Definition of Terms
•Best research evidence is patient centered research that is clinically relevant •Clinical expertise: the ability to use clinical skills and clinical decision-making to identify patients' health states and risks and benefits of interventions. •Patient Values: preferences, concerns and expectations that must be integrated into patients' health care.

Why Evidence-Based Practice?
•Despite an aggressive research movement, the majority of findings from research often are not integrated into practice. •It take approximately 17 hears to translate research findings into practice (if at all) •Without current best evidence, practice becomes rapidly out of date to the detriment of patients. •In order to keep up with the journals relevant to our practice, we need to review 19 articles a day, 365 days of the year!!! •Textbooks may be out of date by the time they are printed •Traditional continuing education conferences do not significannot ly improve clinical practice.

•To advance our profession and enhance life long learning
•In the near future, 3rd party payers will only provide reimbursement for healthcare practices that are supported with evidence. •Practice routed in tradition are often out dated and does not lead to the best patient outcomes oUse of soap and water to massage a bony coccyx or reddened heels in bed-ridden patients Exacerbated condition

oDaily changing of IV dressings every 24 hours
Now done every 72 hours
oPerineal shaves before child birth
Really did nothing
•Rule 5 of the 10 rules for healthcare in Crossing the Quality Chasm is "evidence-based decision making (IOM, 2001) •Competency 3 of the 5 core competencies deemed necessary by the recent Summit on healthcare Professions Education is oEmploy Evidence Based Practice!

What EBP is NOT
•NOT Cookbook care that has no latitude for clinical judgment •NOT Care that excludes patient preferences
•NOT Care that excludes a clinician's expertise
•NOT A process that ignores findings from qualitative and descriptive studies •NOT Something for academicians

Five Steps of EBP
1.Ask the burning clinical question – "Why do we do things this way?" oGive priority to questions that have the most important consequences oAlso give priority to questions that come up more frequently 2.Collect the best evidence

a.Comes from systematic reviews which are also previously called "a meta-analysis" 3.Critically appraise the evidence
oWhat were the results of the study?
oAre the...
