What are the differences between a critically appraised topic CAT paper and a systematic review?
A critically appraised topic (or CAT) is a short summary of evidence on a topic of interest, usually focussed around a clinical question. A CAT is like a shorter and less rigorous version of a systematic review, summarising the best available research evidence on a topic.
How do you write a critical appraisal topic?
These steps are:
- Asking a focused and answerable question that translates uncertainty to an answerable question.
- Searching for the best available evidence.
- Critically appraising the evidence for validity and clinical relevance.
- Applying the results to clinical practice.
How many databases should be searched for a systematic review?
It is important to search two to five databases individually. Only searching one database or using the Library’s MegaSearch is not acceptable. Which databases and how many you choose to search depends on the topic of the systematic review.

- Is the study question relevant to my field?
- Does the study add anything new to the evidence in my field?
- What type of research question is being asked?
- Was the study design appropriate for the research question?
- Did the methodology address important potential sources of bias?

What is the best database for systematic reviews?
Optimal searches in systematic reviews should search at least Embase, MEDLINE, Web of Science, and Google Scholar as a minimum requirement to guarantee adequate and efficient coverage.
Is Google Scholar good for systematic review?
A further study (Bramer et al, 2016) concludes “Despite its vast coverage of the scholarly literature, Google Scholar (GS) is not sufficient to be used on its own as a single database to support SR searching. The reason for this is not low precision in GS searching, which is comparable to traditional databases.

When professionals summarise a single study, the outcome is a critically appraised paper (or CAP). CATs and CAPs are one way for busy clinicians to collate and share their appraisals. Because they are client-centered and based on “real-life” clinical scenarios, CATs should appeal to clinical learners at all levels.
What should be included in the critical appraisal process?
During the critical appraisal process, you will be assessing each study’s risk of bias. See many of the links below to tools often used to critically appraise research studies.
