A Large Surgical Registry for Abdominal Aortic Aneurysms (AAA) (AAA)

In the spirit of improving patient safety and quality of healthcare in our region, the Dallas-Fort Worth Hospital Council Education and Research Foundation (Foundation) and Baylor Research Institute sought and obtained federal funding support (AHRQ grant) to develop an Abdominal Aortic Aneurism (AAA) surgery registry in North Texas. Participating centers will directly benefit from this project and will have access to a de-identified version of the registry data through their collaboration. These data may be used for quality improvement initiatives and/or to conduct your own research. In summary, this effort represents a substantial investment (with no costs to facilities) in improving outcomes for patients with AAA.

Study Overview

• Status: Completed
• Conditions: Abdominal Aortic Aneurism
• Intervention / Treatment: Procedure: endovascular surgery

Detailed Description

Currently, little is known about who receives which type of surgery. What data are available are largely from single-centre studies, with study populations of a few hundred to a thousand patients, comparing outcomes for open and endovascular repair and collecting patient characteristic data largely for risk adjustment. Data on endovascular vs open AAA repair from the population-based registry will provide important information regarding the current use of these two treatment strategies, as well as allowing comparison of long-term outcomes for each according to different patient characteristics.

The proposed registry has the potential to provide means for internal quality assessment for the participating institutions. The de-identified registry will be made available to researchers at their request. This registry, focusing on AAA in the Dallas-Fort Worth metroplex, will provide data with the potential to improve treatments for more than 800,000 patients in the US.
