What is Evidence-Based Practice?
Evidence-based (EBP) is key to delivering the highest quality of healthcare
and ensuring the best possible outcomes.
Why Evidence-based Practice?
With the complexity of healthcare environment today, the call for an EBP
in the provision of care and management
of healthcare consumers is multi-factorial:
Healthcare consumers are demanding higher quality care
Third -party payers wants evidence-based interventions and treatment
The need to contain health care cost
The existence of Pay-for-performance( P4P)
As shown in the diagram below,when best evidence from best research
meets clinical information and patient
values, needs, characteristics,preferences, and expectations,optimal
patient outcome. This Venn diagram shows the relationships
among 5 concepts. Three circles in the middle of
the graphic overlap with each other: 1) “Best available
research evidence,” 2) “Resources, including practitioner
expertise,” and 3) “Populations characteristics, needs,
values, and preferences.” Overlapping these 3 circles
and in the center is the circle “Decision-making.” This group of 4 circles is surrounded by “Environment and
0. Cultivate a spirit of inquiry
1. Ask the burning question in PICOT format
2. Search for and collect the most relevant best evidence
3. Critically appraise the evidence( i.e., rapid critical appraisal, evaluation, & synthesis).
4. Integrate the best evidence with one’s clinical expertise and patience preferences,
expectations, needs and values in making a practice decision or change
5. Evaluate outcomes of the practice decision or change.
6. Disseminate the outcomes of the EBP decision or change
Level I: Evidence from a systematic review of all relevant randomized controlled trials (RCT’s),
Level II: Evidence obtained from at least one well-designed Randomized Controlled Trial (RCT)
Level III: Evidence obtained from well-designed controlled trials without randomization,
Level IV: Evidence from well-designed case-control and cohort studies
Level V: Evidence from systematic reviews of descriptive and qualitative studies
Level VI: Evidence from a single descriptive or qualitative study
Level VII: Evidence from the opinion of authorities and/or reports of expert committees
