[The six steps necessary in elaborating critically appraised topics].

Area of Science:

• Diagnostic Imaging Evidence Appraisal
• Clinical Decision Support

Background:

• Critically Appraised Topics (CATs) are essential for synthesizing evidence in diagnostic imaging.
• CATs can address diverse questions, including test comparisons, screening efficacy, economic analyses, and therapeutic implications.

Purpose of the Study:

• To outline the six fundamental steps involved in elaborating a CAT.
• To describe the nuances of each step tailored to different study designs within diagnostic imaging.

Main Methods:

• Defining the clinical question.
• Conducting systematic and efficient bibliographic searches.
• Appraising levels of evidence and critically reading selected articles.
• Applying findings to clinical context and formulating recommendations.

Main Results:

• The study details a structured six-step methodology applicable to various CAT types.
• It highlights how study design selection (e.g., clinical trials vs. systematic reviews) impacts evidence relevance and conclusion strength.

Conclusions:

• A standardized six-step process facilitates the creation of robust CATs in diagnostic imaging.
• Tailoring the approach based on the specific clinical question and available evidence ensures the generation of clinically relevant recommendations.
