Abstract
BACKGROUND: It is important to investigate the factors that may delay the diagnosis and treatment process of ischemic stroke. The aim of this study was to investigate whether in-hospital mortality increased in patients who presented to the emergency department out-of-hours and underwent thrombectomy. METHODS: A total of 59 patients who applied to the emergency department between January 1, 2018 and November 1, 2021 and underwent thrombectomy due to ischemic stroke were included in the study. Patient age, gender, thrombectomy success (successful recanalization), in-hospital mortality status, intracranial hemorrhage status after thrombectomy, and out-of-hours admission status were recorded and compared according to out-of-hours admission status. RESULTS: Twenty-seven (45.8%) patients were male, and the median age was 74 (61-81) years. Forty-two (71.2%) patients applied to the emergency department out-of-hours. In-hospital mortality occurred in 27 (45.8%) patients. There was no statistically significant difference in out-of-hours admission status between the non-survivor group and the survivor group (non-survivor: 24 [75%]; survivor: 18 [66.7%], p = 0.481). Nor was a statistically significant difference found in the intracranial hemorrhage complication rate of the patients admitted out-of-hours compared to the patients admitted during working hours (out-of-hours: 17 [40.5%]; during working hours: 6 [35.3%], p = 0.712). CONCLUSION: No statistically significant difference was found in the rate of in-hospital mortality and intracranial bleeding complications in patients who underwent thrombectomy out of working hours compared to during working hours.
