Definition of  "evidence based medicine"


  1. Evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. 
  2. Evidence-based practice is “the conscientious and judicious use of current best evidence in conjunction with clinical expertise and patient values to guide health care decisions.”  (Titler, 2008).


How are evidence based medicine and evidence based nursing different?


Both evidence-based medicine and evidence-based nursing are forms of evidence-based practice.  However, nursing’s approach to evidence-based practice may differ from the biomedical model. Nurses provide holistic care, treating and working with patients rather than working on them. When nurses make clinical decisions about therapeutic interventions, they frequently consider not only effectiveness of treatment, but also cost-effectiveness and acceptability to the patient.

EBM Pyramid


Consider the pyramid to be a visual representation of the entirety of clinical biomedical information. 

  • The list of resources on the Evidence-Based Resources tab above are listed hierarchically top to bottom based on the pyramid. 
  • Start at the top of the list and move down until you find a resource that answers your question – you can then feel confident that you have discovered the Best Evidence available on your topic.
  • Moving up the pyramid, resources are developed using more robust methodology which lessens bias and leads to stronger Evidence-Based findings but are fewer in number.  Resources at the bottom of the pyramid are plentiful but are not necessarily Evidence-Based in their approach or findings. 


Evidence-based nursing practice is a 5 step systematic process which leads the DNP to apply quality evidence from research to make effective decisions about clinical and other healthcare problems. 


These steps include:

  • Asking the Clinical Question
  • Evidence Acquisition
  • Evidence Appraisal
  • Evidence Application
  • Outcome Evaluation
