What is a CAT?



A Critically Appraised Topic (CAT) is a structured, short (3-4 pages max) summary of evidence on a topic of interest, usually focused around a practical problem or question. A CAT is like a “quick and dirty” version of a systematic review, summarizing the best available research evidence on a topic. Usually more than one study is included in a CAT.


Key parts of a CAT include:


1)      Question

2)      Background

3)      PICOC

4)      Search strategy

5)      Results

6)      Conclusion

7)      Limitations

8)      Recommendation

9)      References
