Abstract
Objective
Spontaneous hemorrhagic stroke is a devastating disease with high mortality and grave neurological outcomes worldwide. This study aimed to evaluate the association between the elapsed time from emergency department (ED) visit to emergency neurosurgery and clinical outcomes in patients with spontaneous hemorrhagic stroke.
Methods
A nationwide cross-sectional study was conducted using the nationwide emergency database in Korea. Spontaneous hemorrhagic stroke patients who received neurosurgery within 12 hours of ED visit between January 2018 and December 2019 were enrolled. The main exposure was time to neurosurgery and the primary outcome was in-hospital mortality. Multivariable logistic regression was conducted.
Results
Among 2,602 study populations (incidence rate: 2.5 per 100,000 person-years, 15.8% of SAH, 78.6% of ICH, and 5.6% of mixed type), 525 (20.2%) patients received surgery in the ultra-early (0–2 hours) group, 1,093 (42.0%) in the early (2–4 hours) group, and 984 (37.8%) in the late (4–12 hours) group. The early group showed better survival outcomes than the ultra-early and late group (in-hospital mortality 22.2% vs. 26.5% and 26.1%, p = 0.06). Compared to the late group, adjusted OR (95% CI) for in-hospital mortality was 0.78 (0.63–0.96) for the early group, while there was no significant difference in the ultra-early group (0.90 (0.69–1.16)).
Conclusions
Early neurosurgery within 2–4 hours of the ED visit was associated with favorable survival outcomes in patients with spontaneous hemorrhagic stroke.
