(Request a copy)Background and Purpose- Whether maximal treatment should be offered to elderly patients suffering from poor-grade aneurysmal subarachnoid hemorrhage (aSAH) is controversial. The survival of patients in this subgroup beyond the usual outcome measurements 6 to 12 months after aSAH is unclear. The purpose of this study is to provide survival and outcome data to support clinicians making decisions on treatment for this subgroup of patients. Methods- We performed a retrospective analysis of the Bernese SAH database for poor-grade (World Federation of Neurosurgical Societies grade IV and V) elderly patients (age ≥60 years) suffering from aSAH admitted to our institution from 2005 to 2017. Patients were divided into 3 age groups (60-69, 70-79, and 80-90 years). Survival analysis was performed to estimate mean survival and hazard ratios for death. Binary logarithmic regression was used to estimate the odds ratio for favorable (modified Rankin Scale score of 0-3) and unfavorable (modified Rankin Scale score of 4-6) outcome. Results- Increasing age was associated with an increasing risk of death after aSAH. The hazard ratio increased by 6% per year of age ( P<0.001; hazard ratio, 1.06; 95% CI, 1.03-1.09) and 76% per decade ( P<0.001; hazard ratio, 1.76; 95% CI, 1.35-2.29). Mean survival was 56.3±8 months (patients aged 60-69 years), 31.6±7.6 months (70-79 years), and 7.6±5.8 months (80-90 years). Unfavorable outcomes 6 to 12 months after aSAH were strongly related to older age. The odds ratio increased by 11% per year of age ( P<0.001; odds ratio, 1.11; 95% CI, 1.05-1.18) and 192% per decade ( P<0.001; odds ratio, 2.92; 95% CI, 1.63-5.26). Conclusions- Risk for death and unfavorable outcome increases markedly with older age in elderly patients with poor-grade aSAH. Despite a high initial mortality, treatment resulted in a reasonable proportion of favorable outcomes up to 79 years of age and only a small number of patients who were moderately or severely disabled 6 to 12 months after aSAH. Mean survival and proportion of favorable outcomes decreased markedly in patients older than 80 years.
