Abstract
OBJECTIVE: To investigate the effect of emergency medical service (EMS) on the prognosis of ischemic stroke patients treated with intravenous thrombolysis. METHODS: Clinical data of 2123 ischemic stroke patients treated with intravenous thrombolysis in 70 hospitals in Zhejiang province were retrospectively analyzed. There were 808 patients sent to the hospital by ambulance (EMS group) and 1315 patients by other transportations (non-EMS group). Good outcome was defined as modified Rankin Scale (mRS) ≤ 2 at 3-month. The onset to needle time (ONT), onset to door time (ODT), door to needle time (DNT) and outcome were compared between EMS group and non-EMS group. Binary logistic regression was used to explore the influencing factors for the outcome at 3-month. RESULTS: Compared with the non-EMS group, patients in the EMS group were older, with higher baseline National Institute of Health Sroke Scale (NIHSS) score, and had a higher proportion of atrial fibrillation (all P<0.05), but there were no significant differences in ONT, ODT and DNT between two groups (all P>0.05). Binary logistic regression showed that EMS was not independently associated with good outcome (OR=0.856, 95%CI:0.664-1.103, P>0.05). CONCLUSIONS: EMS had not improve the outcome of patients receiving intravenous thrombolysis in Zhejiang province.
