Use of the 11-Item Modified Frailty Index to Determine Accurate Prognosis and Revascularization Strategy in Patients Undergoing Vascular Bypass Surgery for Intermittent Claudication.

The mFI-11 was a helpful tool in predicting OS for patients with IC who underwent vascular bypass surgery. Those with H should not undergo open revascularization; however, for IC patients who have either not responded to a regimen of exercise and medication, or have specifically requested a more aggressive approach, obtaining a good score in frailty assessment is useful in determining whether or not bypass surgery would be a viable option.
