Validation of a modified Frailty Index to predict mortality in vascular surgery patients

The mFI was a better discriminator of mortality than other risk indices; however this was only significant for the open cohort. The mFI was also a better discriminator of class IV complications for the open and endovascular AAA repair groups. These data suggest that mFI should be used in place of previously recognized risk indices to define perioperative mortality after open vascular surgery and risk of major complications after aneurysm repair.
