Clinical practice guidelines are developed under the aegis of the AGA Institute Clinical Guideline Committee and provide preferred approaches to specific medical problems or issues. 

These documents are not to be construed as standards of care. All decisions regarding the care of a patient should be made by the physician in consideration of all aspects of the patient's specific medical circumstances.

A comprehensive background paper, the technical review, provides the user of the clinical practice guideline with the evidence used to formulate a particular recommendation and the strength and character of that evidence.
