Key result
Endovascular and open abdominal aortic aneurysm repair had similar 30-day readmission rates (13.3% vs 12.8%); 1-year mortality was higher in readmitted patients (23.4% vs 4.5%, P<0.001).
Why the study?
Does endovascular aneurysm repair compared to open repair affect 30-day readmission rates in Medicare beneficiaries undergoing elective AAA repair?

Readmission after elective AAA repair identifies patients at high 1-year mortality risk regardless of approach; leaves open whether complication-targeted interventions alter outcomes.

Does endovascular aneurysm repair compared to open repair affect 30-day readmission rates in Medicare beneficiaries undergoing elective AAA repair?
Absolute Event Rate: 13.3% vs 12.8%
Early readmission after AAA repair is common regardless of surgical approach, is primarily driven by postoperative complications, and is associated with a markedly increased 1-year mortality.
Greenblatt et al. (2012) conducted a cohort in Abdominal aortic aneurysm (n=2,481). Endovascular aneurysm repair (EVAR) vs. Open aneurysm repair was evaluated on 30-day readmission. Endovascular and open abdominal aortic aneurysm repair had similar 30-day readmission rates (13.3% vs 12.8%); 1-year mortality was higher in readmitted patients (23.4% vs 4.5%, P<0.001).
