The EBP Process

2. Acquire: Acquire clinical evidence using EBP resources.3. Appraise: Critically evaluate the evidence you have collected.

Purpose of  the study

Study Design

(RCT, Qualitative, Quantitative, Mixed)

Theory/ Framework

Study Sample

Instrument/ Means of Collecting Data

Study FIndings


Compare lab rats to other potential study control groups, [i.e. alley cats, sharks, attorneys, mice, etc.] for suitability in terms of cost and potential emotional attachment to the subjects


Erickson, Tomlin & Swain, Modeling

& Role­Modeling

Theory (MRM)

N= 30

30 question survey

Slight increase in emotional attachment to smaller, furrier subjects. More research is needed to confirm.

From the Centre for Evidence Based Medicine website:

 "no evidence ranking system or decision tool can be used without a healthy dose of judgment and thought."1

That said, the CEBM Levels of Evidence, 2011 edition, provides something more than the traditional pyramid progressions of various research or study types. The pyramid is still a very useful graphic, but the CEBM table provides a bit more nuance while acting as a shortcut for busy clinicians, patients and others.
