Patients were classified as or weekdays admission groups. Dates in-hospital mortality one-year obtained Death Registry. Results no difference group weekday with aneurysm (45.4% vs 45.3%, adjusted odds ratio [OR] 1.01, 95% confidence interval [CI] 0.87–1.17, p = 0.93), infarction (15.8% 16.2%, OR 0.98, CI 0.95–1.00, 0.10), stroke (4.1% 4.2%, 0.99, 0.96–1.03, 0.71), (14.6% 14.6%, 1.02, 0.92–1.15, 0.66). results remained for 1 year all emergencies.
