The following study states that The Agency for Healthcare Research and Quality Patient Safety Indicators (PSI) are quality improvement indicators used to determine hospital performance and, increasingly, to rank surgical programs. The American College of Surgeons National Surgical Quality Improvement Program and the Society for Vascular Surgery Vascular Quality Improvement databases are also frequently used to compare outcomes, but definitions of complications vary between the systems and the optimal system for tracking complications in complex endovascular repair remains unclear. Herein we assess the three outcome tracking systems and their ability to capture complications after fenestrated endovascular abdominal aortic aneurysm repair (FEVAR) and open aortic aneurysm repair in a large complex aortic program. Demographic and operative data for patients undergoing repair of juxtarenal or pararenal aortic aneurysms between 2004 and 2018 via both open and FEVAR approaches at the Johns Hopkins Medical Institutions were compiled in a prospectively maintained retrospective database.
