National Guideline Clearinghouse guideline syntheses and comparisons.

As the number of clinical practice guidelines relevant to clinical practice continues to grow, nurse practitioners may find it confusing to choose from two or more guidelines on the same or similar topics. The National Guideline Clearinghouse provides two resources to assist clinicians in comparing multiple guidelines on similar topics: guideline syntheses and guideline comparisons. This column describes the features of these two resources, using examples from guidelines on acute pharyngitis.
