Abstract: Background and Objective: The aim was to investigate reasons for a pre-hospital delay in patients with acute ischemic stroke (AIS) and patients within the thrombolytic window who did not receive thrombolysis. Subjects and Methods: This study was conducted on AIS patients admitted to the stroke center through interviews and questionnaires. Results: Of the 160 consecutive patients included, 67 (41.9%) arrived at the emergency department (ED) within 4.5 h, and 93 (58.1%) were delayed. The early arrival patients had shorter median onset-to-arrival times ( P < 0.001). Of the 93 delayed patients, 70 (75.3%) were unaware of the occurrence of a stroke, and 17 (18.3%) had the stroke onset during sleeping. Multivariate logistic regression analysis showed that private car odds ratio (OR) 4.310, 95% confidence interval (CI) 1.732–10.728 and other traffic tools (OR 6.189, 95%CI 1.843–20.786) were independent of a delayed arrival, whereas symptomatic remission, symptomatic aggravation, education of stroke, and the Oxfordshire Community Stroke Project classification were independently related to early arriving at the hospital after a stroke. Of the 67 patients, 33 (49.3%) who arrived within the window time did not receive thrombolytic therapy. Except for minor stroke ( n = 9/27.3%) and contradictions ( n = 2/6.1%), the main reasons for pre-hospital delay were patients’ refusal ( n = 12/36.4%) and misdiagnosis on the part of the physician due to atypical symptoms ( n = 4/12.1%). Conclusions: Lack of stroke education, symptom stabilization, and non-emergency medical system utilization were the main reasons for the pre-hospital delay. Patients’ refusal and misdiagnosis were the main reasons of patients who were eligible for thrombolytic treatment but did not finally receive thrombolysis.
