Study design
t‐PA
This study employed a prospective design to compare the outcomes of patients with AIS who received 5G MSU care with those who did not. The 5G MSU is equipped with non‐spiral computerized tomography (CT) and related diagnostic instruments, serving as a prehospital emergency system that integrates neurological examination, CT diagnosis, and intravenous thrombolytic therapy. Prior to enrollment, patients were assigned to receive either EMS or 5G MSU care. Ambulance services were provided by Ya'an People's Hospital. For practical reasons, a two‐shift schedule was implemented for both 5G MSU and EMS, with day shifts from 8 a.m. to 8 p.m. and night shifts from 8 p.m. to 8 a.m. The 5G MSU and EMS shifts alternated weekly. Follow‐up assessments of patients were scheduled at day 7 and day 90 post‐discharge, with follow‐up data collected through the WeChat app on their phones. Group assignment was not blinded for data collection. Participants were excluded if they were ineligible for tissue plasminogen activator (t‐PA) treatment or if they were not accessible for follow‐up data (Figure Flow chart of the experiment.
