Abstract

Background While endovascular procedures can be performed by neurosurgeons and neuroradiologist compared to microsurgery that can only be performed by neurosurgeons, we hypothesize that patients with aneurysmal subarachnoid hemorrhage on weekdays have better functional outcomes on follow-up compared to those treated on weekends.

Objective Compare functional outcomes up to 3 months of follow-up in patients treated on weekends and weekdays for aneurysmal subarachnoid hemorrhage. Methods: This is a retrospective review of ruptured aneurysms presenting with aneurysmal subarachnoid hemorrhage on weekdays and weekends between 2017 and 2022 at our institution.

Results The study cohort comprised of 583 patients divided into 422 receiving treatments on weekdays vs 161 on weekends. There were no significant differences in patient and aneurysmal characteristics between both cohorts except that mean aneurysm height was significantly higher in the weekday cohort (4.5±2.9 mm vs 4±1.9 mm, p=.02). Functional outcome at discharge, 1 month of follow-up and 3 months of follow-up was comparable between both cohorts. Also, the rate of open and endovascular treatment was comparable between both cohorts (open: weekday 9% vs weekend 6.2%, endovascular: weekday 91% vs weekend 93.8%, p=.27). Lastly, the rate of complications, mortality, aneurysmal occlusion, recurrence, and retreatment was comparable between both cohorts.

Conclusion Our study demonstrated that treatment of aneurysmal subarachnoid hemorrhage on weekends or weekdays did not affect functional outcome up to 3 months of follow-up. Large tertiary centers with multidisciplinary teams on call are therefore recommended in order to safeguard patient outcomes regardless of admission date.
