This study used the Vascular Quality Initiative (VQI) abdominal aortic aneurysm (AAA) registries to determine current compliance with and impact of recent Society for Vascular Surgery (SVS) AAA guidelines. Recommendations from the SVS AAA guidelines were reviewed and assessed as to whether they could be evaluated with current VQI data sets. The degree of compliance with these individual recommendations was calculated by center and correlated with clinical outcomes. Data were analyzed by univariate analysis and mixed effects multivariable logistic regression. Statistical significance was measured at P < .05.

The results states that out Of the 111 SVS recommendations, 10 could be evaluated using VQI registries. The mean center-specific compliance rate ranged from 40% (smoking cessation 2 weeks before open AAA.
