What is EBP?

Evidence Based Practice (EBP) is "the use of best research evidence, along with clinical expertise, available resources, and the patient's preferences to determine the optimal management options in a specific situation" (Liamputtong, 2013, p. 453). 


EBP is about making clinical decisions based on the best available evidence from scientific research. In addition, the knowledge and experience of the care provider and the values and norms of the individual patient are also important.

What is CAT?

A Critically Appraised Topic (CAT) is a concise summary of the existing evidence on a particular (medical) topic, and an analysis of how strong this evidence is. A well-written CAT forms a basis from which Evidence Based Practice is possible.


At the beginning of a CAT you formulate a PICO question. PICO stands for Patient, Intervention, Comparison and Outcome. Read more about drafting PICO questions here.


Based on your PICO question, you will look for the strongest evidence in the scientific literature. You do this by thinking carefully about relevant search terms and searching in the right place. Thanks to your own formulated inclusion and exclusion criteria, you are left with a small number of suitable scientific sources to copy your CAT.


Assessing the strength of a particular source is done on the basis of Critical Appraised Tools, which are checklists for different types of sources with which you can assess the quality. Here you will find more information about various Critical Appraised Tools.
