Predictors for Functional Outcome in Patients with Aneurysmal Subarachnoid Hemorrhage Who Completed In-Hospital Rehabilitation in a Single Institution

Background: Although many studies evaluated independent prognosis factors of functional outcome in patients with subarachnoid hemorrhage (SAH) at a suitable time point, some patients take a long time to get functional improvement. The purpose of this study is to evaluate predictors for functional outcome in SAH patients who underwent surgical clipping and in-hospital rehabilitation in our single institution using Modified Rankin Scale (MRS) and Barthel Index (BI). Methods: Two-hundred fifty-one SAH patients were admitted to our hospital from January 2008 to December 2017. Of them, 144 patients who diagnosed aneurysmal SAH, underwent surgical clipping within 72 hours, and completed subsequent in-hospital rehabilitation were included in this study. We explored their clinical variables and evaluated the relationships between those factors and functional outcome using MRS and BI. Results: In multivariate analysis, independent prognostic factors of both MRS and BI were age, World Federation of Neurologic Surgeons grade, and symptomatic vasospasm. Conclusions: We suggest that age, SAH severity, and symptomatic vasospasm are associated with functional outcome in patients with aneurysmal SAH who completed surgical clipping and in-hospital rehabilitation.
