BackgroundTime has shown to be a relevant factor in the prognosis for a multitude of clinical conditions. The current analysis aimed to establish whether delayed admission to specialized care is a risk factor for increased mortality in case of high-grade aneurysmal subarachnoid hemorrhage.Material And MethodsConsecutive patients with aneurysmal subarachnoid hemorrhage were enrolled retrospectively if they had a World Federation of Neurological Surgeons Grading System grade of 5. Predictor variables for in-hospital mortality reflecting demographic, spatial, temporal treatment, and neurological factors were recorded from hospital medical records and emergency physicians' reports. We performed statistical analysis on the influence between the predictor variables and in-hospital mortality.ResultsThe study included 61 patients with an average age of 58 years. The overall in-hospital mortality rate was 28% (17/61 patients). A delayed transport to specialized neurosurgical care was associated with increased in-hospital mortality. Transportation time was mainly prolonged in cases where an alternative diagnosis was made by the emergency physician. Mortality was highest in patients with cardiovascular complications of subarachnoid hemorrhage.ConclusionDelayed admission to specialized care is associated with a higher mortality rate in patients with high-grade aneurysmal subarachnoid hemorrhage. Accompanying non-neurosurgical, mainly cardiac complications might be a significant factor leading to delayed admission. The emergency physician should be aware that cardiovascular abnormalities are a relevant complication and sometimes the first identified clinical feature of high-grade subarachnoid hemorrhage.Copyright © 2016 Elsevier Inc.
