Hospital and Surgeon Annual Volume Thresholds Associated With Improved 30-Day Mortality After Fenestrated and Branched Aortic Repair

Key Result

Higher hospital and surgeon annual volumes are significantly associated with improved 30-day mortality after fenestrated and branched aortic repair.

Key Points

The study investigates how hospital and surgeon annual volumes affect 30-day mortality rates after aortic repair procedures.
Analyzed volume-outcome data from hospitals performing fenestrated and branched aortic repairs.
Assessed the association between annual hospital and surgeon volumes and patient outcomes after surgery.
Higher annual volumes are linked to lower 30-day mortality rates after fenestrated and branched aortic repairs.
Establishing volume thresholds can help guide the use of these aortic repair technologies.

Structured PICO

Does high hospital and surgeon annual volume improve 30-day mortality in patients undergoing F/BEVAR?

Population

Patients undergoing Fenestrated and Branched Aortic Repair (F/BEVAR)

Intervention

High hospital and surgeon annual volume

Comparator

Low hospital and surgeon annual volume

Outcome

30-day mortalityhard clinical

Higher hospital and surgeon annual volumes are associated with improved 30-day mortality after fenestrated and branched aortic repair.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

There is a significant volume-outcome relationship after F/BEVAR. As commercially available devices become available, volume thresholds may provide an opportunity to guide dissemination of the technology while ensuring acceptable patient outcomes.
