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.
For a more in-depth definition of EBM, see:
Gordon Guyatt; Roman Jaeschke; Mark C. Wilson; Victor M. Montori; W. Scott Richardson
For an oral history of EBM, see:
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?|
