Abstract: Objective To evaluate whether improving emergency medical procedures can impact the door-to- needle time(DNT), the time required when acute ischemic stroke patients have been hospitalised to be treated by intravenous thrombolysis. Methods During January to April in 2015, the experimental group consists of the acute ischemic stroke patients treated by intravenous thrombolysis with recombinant tissue plasminogen activator(rt-PA). After starting the green channel, nurses have to immediately mark the patients clearly, write the triage nurse’s screen into the management process and move the rt-PA thrombolytic place from ward to the emergency room simultaneously. The acute ischemic stroke patients treated by intravenous thrombolysis with rt-PA before the process improvement during January to April in 2015 are considered as the control group. Then we evaluate the DNT between the two groups. Results In control group, the median duration of DNT is 133(80-174) min, while the experimental group’s DNT median duration is 102(56-168) min, the two groups have significantly difference( P =0.011). Conclusion Adopt the integrated implementation carried out by multi-disciplinary cooperation and optimize the emergency medical treatment process can reduce the in-hospital delays of rt-PA intravenous thrombolysis.
