Overview

Hospital volume may warrant prioritization for thoracic aortic referrals; leaves open optimal thresholds and causal mechanisms for prospective study.

Hospital volume, rather than individual surgeon volume, is associated with reduced mortality in thoracic aortic surgery, emphasizing the importance of institutional and team organization.

Limitations

  • Volume itself is a proxy measure for other factors
  • Mortality is often used as the sole end-point, ignoring morbidity and quality of life
  • High-volume centers may develop unorthodox behaviors due to workload
