In 20 qualified hospitals, the number of patients with acute stroke treated with rt-PA thrombolysis increased from 568 to 802, and the rate of rt-PA thrombolysis increased from 8.3% to 9.7%. The number of patients treated with endovascular thrombectomy increased from 60 to 136, and the rate of patients treated with endovascular thrombectomy increased from 0.9% to 1.6%. Furthermore, the median time between receipt of the call and arrival on the scene decreased significantly. In Shenzhen Second People’s Hospital, the median onset-to-needle time and door-to-needle time for rt-PA-treated patients decreased by 26 min and 20 min, respectively. The proportion of rt-PA-treated patients within various geographical distances of Shenzhen Second People’s Hospital did not differ significantly.
