BackgroundThe number of elderly patients with aneurysmal subarachnoid hemorrhage (aSAH) admitted to intensive care units (ICUs) has increased. We aimed to analyze the characteristics and outcomes of such patients in a tertiary university hospital during a 5-year period.MethodsA retrospective single-center analysis was performed of patients with aSAH ≥70 years old admitted to a tertiary neuro-ICU during January 2014-May 2019 based on medical records and computed tomography scans. The primary outcome was functional outcome at 12 months. We used multivariable logistic regression to assess factors associated with unfavorable outcome (Glasgow Outcome Scale score 1-3 and institutionalized).ResultsOf 117 included patients, 49% had a favorable outcome at 12 months, and mortality was 41%. In multivariable analysis, poor-grade aSAH and intraventricular hemorrhage were predictors of poor outcome (odds ratio, 4.7, 95% confidence interval, 1.7-12.5 and odds ratio, 2.8, 95% confidence interval, 1.1-7.2, respectively). None of the patients with a Glasgow Coma Scale (GCS) motor score of 1-3 three days after admission was alive at 12 months. In contrast, 65% of those with a GCS motor score 6 had favorable outcome.ConclusionsHalf of elderly patients with aSAH admitted to a neuro-ICU were able to live at home after 12 months. Mortality was significant, but the number of severely disabled patients was low. Clinical status at admission was the strongest predictor of outcome, whereas intraventricular hemorrhage increased the risk of poor outcome as well. GCS motor score 3 days after admission seemed to predict mortality and outcome.Copyright © 2020 Elsevier Inc. All rights reserved.
