Resources and information relevant to the topics discussed in NURS 7220-OL.


Evidence based practice (EBP) is the conscientious use of current best evidence in making decisions about patient care (Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000).

5 steps to the EBP Process: 

    ASK a Clinical Guiding Question
    ACQUIRE the Best Evidence 
    APPRAISE the evidence 
    APPLY the Evidence with One’s Clinical Expertise 
    ASSESS the Outcomes of the EBP Practice Decision

Levels of evidence pyramid

The levels of evidence pyramid provides a way to visualize both the quality of evidence and the amount of evidence available. For example, systematic reviews are at the top of the pyramid, meaning they are both the highest level of evidence and the least common. As you go down the pyramid, the amount of evidence will increase as the quality of the evidence decreases.
