What is Evidence-Based Medicine?

Evidence-Based Medicine is the practice of using high-quality research, clinical expertise, and patient values to make clinical decisions about prevention, treatment, or management of illness.

Evidence-Based Medicine Practice Model

Finding and using evidence to inform clinical decisions involves a five-step investigative process.  This Guide focuses on explaining steps 1-3.    

EBM Practice Model:  

1 Ask a well-defined, answerable clinical question.  Use the PICO framework to define the question.  
2 Acquire the best available evidence from the literature.   
3 Appraise the literature for relevancy, currency, validity, and applicability.  
4 Apply the evidence to the clinical situation.
5 Assess the effectiveness of the intervention.  Did it improve the outcome?
