This study aims to elucidate the impact of frailty on spontaneous intracranial hemorrhage (SICH) patient outcomes in the United States.This is a single center retrospective chart review of all adult patients (≥18 years old) admitted with a primary diagnosis of SICH due to hypertension, amyloid angiopathy, and coagulopathy from 2014-2017. The studied variables included length of stay, age, sex, ICH score variables, medications, and frailty as measured by the modified Frailty Index (mFI).A total of 240 patients with 248 SICH were included in the analysis. In this study, mFI was not predictive of overall mortality (p = 0.12). To further investigate this issue, patients with ICH scores of 2 or 3 were separately analyzed to assess the impact of mFI on moderate ICH cases. However, mFI was also not associated with increased hospital mortality in moderate ICH cases (p = 0.812). In bivariate Spearman analysis, mFI significantly correlated with several outcome measures including modified Rankin Scale (MRS) at discharge (p = 0.01), but ICH score also correlated with these outcomes (p 0.001). Although ICHmFI scores were both predictive of MRS with linear regression, multivariate demonstrated that the ICH score was the only independent risk factor for MRS (p = 0.698, p 0.001 respectively).Frailty, as measured by the mFI, was not an independent risk factor for increased mortality or worse outcomes in SICH patients. This study does not support incorporating the mFI score for SICH patients for prognostication.
