The 11-Item Modified Frailty Index as a Tool to Predict Unplanned Events in Traumatic Brain Injury.

Background: Frailty has been studied extensively in trauma, but there is minimal research detailing its impact on traumatic brain injury (TBI). We hypothesized that the 11-item modified frailty index (mFI-11) would predict complications and discharge outcomes in patients with TBI.

Methods: A retrospective review of our trauma quality improvement program (TQIP) registry was conducted for all patients with TBI.
