Comments

Critically Appraised Topics (CAT) are valuable tools for providers. Unlike a clinical practice pathway, a CAT answers one specific question.  As needed a CAT may be updated or revised as new evidence is published. Primary files will always be the most current CAT. Previous revisions are available upon request from Children’s Mercy Library Services.
