Screening and Managing Abdominal Aortic Aneurysms at the Ochsner Clinic: Suggested Algorithm and Method of Derivation

An algorithm for screening and management of abdominal aortic aneurysms was developed at the Ochsner Medical Institutions to address the considerable variation identified in clinical practice. A consensus panel of physicians whose opinions differed regarding the management of abdominal aortic aneurysms was convened to develop the algorithm. Based on a literature review and clinical experience, the panel established criteria to determine how frequently and by which methodologies patients with abdominal aortic aneurysms should be followed and when a referral to a vascular surgeon is appropriate. The algorithm developed by the consensus panel method was used to establish practice guidelines that are flexible enough to address individual patient needs yet structured enough to eliminate inappropriate care. Data are being collected and analyzed in real time to determine whether elements of the algorithm should be revised.
