Abstract

Background: Pre-hospital delay was a critical factor affecting stroke patients receiving intravenous thrombolytic therapy. The aim of this study was to explore the factors associated with pre-hospital delay and thrombolysis in China.

Methods: Patient data were obtained from emergency department (ED), and the factors of patient pre-hospital delay were recorded through a well-designed form.

Results: A total of 630 patients were eventually included in the study. 317 patients were admitted to the ED during the thrombolysis time window, and only 105 patients received intravenous thrombolytic therapy. In the univariate analysis, transportation (OR: 0.15; 95% CI: 0.44 - 0.518; p = 0.001), atrial fibrillation (OR: 0.555; 95% CI: 0.372-0.828; p = 0.004) and response of symptoms (OR: 0.002; 95% CI: 0.000-0.013; p = 0.000) were associated with early arrival. Speech disturbances (OR: 2.095; 95% CI: 1.294-3.391; p = 0.002), smoking (OR: 2.563; 95% CI: 1.527-4.304; p = 0.000), alcohol consumption (OR: 2.155; 95% CI: 1.159-4.005; p = 0.014) and referral presentation (OR: 2.837; 95% CI: 1.584-5.082; p = 0.000) were associated with thrombolysis. In the logistic regression analysis, direct visiting to the hospital after onset and rushing to emergency after onset were independent predictor of early arrival of AIS and intravenous thrombolytic.

Conclusions: The pre-hospital delay of acute ischemic stroke in China was still serious. Strengthening the ability to identify stroke-related symptoms and establishing a mutual referral medical support service model between lower and upper hospitals may effectively shorten the pre-hospital delay of stroke patients.
