Guidelines

The AGA Institute utilizes the GRADE system (Grades of Recommendation Assessment, Development and Evaluation) to create evidence-based clinical recommendations. Click here to read the process by which AGA Institute clinical practice guidelines are developed.

Existing AGA guidelines are regularly reviewed by members to assess whether they are in need of updating. Read about the AGA Institute’s guideline update process here.

The AGA Institute may also endorse other societies’ guidelines that meet the rigorous criteria for evidence-based clinical recommendations set forth by the Institute of Medicine. Click here to read about the AGA Institute’s criteria and methods for endorsing guidelines.

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.
