Frailty predicts worse outcomes after intracranial meningioma surgery irrespective of existing prognostic factors.

Objective: Frailty has been recognized as a predictor of adverse surgical outcomes across multiple surgical disciplines, but until now the relationship between frailty and intracranial meningioma surgery has not been studied. The goal of the present study was to determine the relationship between increasing frailty (determined using the modified Frailty Index [mFI]) and intracranial meningioma resection outcomes (including hospital length of stay [LOS], discharge location, and reoperation and readmission rates).

Methods: This is a single-center retrospective cohort study of patients who underwent intracranial meningioma resection between August 2012 and May 2018.
