Key result
Patients with aneurysmal subarachnoid hemorrhage admitted between 2007-2011 had a lower rate of favorable functional outcome compared to those admitted between 2001-2006 (51% vs 57%, p<0.03), largely due to being older and in worse clinical condition at admission.

Admission severity and age explain temporal outcome differences; supports prioritizing baseline risk factors over treatment modality in aneurysmal subarachnoid hemorrhage research.

Functional outcome after aneurysmal subarachnoid hemorrhage is primarily determined by patient age, initial clinical condition, and bleeding severity rather than the specific modality of aneurysm treatment.
Ronne-Engström et al. (2013) conducted a cohort in Aneurysmal spontaneous subarachnoid haemorrhage (n=1,124). Admission between 2007-2011 vs. Admission between 2001-2006 was evaluated on Favourable functional outcome (Glasgow Outcome Scale 4-5) (p=<0.03). Patients with aneurysmal subarachnoid hemorrhage admitted between 2007-2011 had a lower rate of favorable functional outcome compared to those admitted between 2001-2006 (51% vs 57%, p<0.03), largely due to being older and in worse clinical condition at admission.
