Comparing 5G mobile stroke unit and emergency medical service in patients acute ischemic stroke eligible for t‐PA treatment: A prospective, single‐center clinical trial in Ya'an, China

Abstract

AbstractBackgroundThis study aims to assess and compare the functional outcomes of patients with acute ischemic stroke (AIS) eligible for tissue plasminogen activator (t‐PA) treatment who received care from either a fifth‐generation(5G) mobile stroke unit (MSU) or traditional emergency medical service (EMS).MethodThe study recruited patients between February 2020 and January 2022, with the final 90‐day follow‐up concluded in April 2022. Prior to enrollment, patients were assigned to either EMS or MSU care based on predetermined rules. The primary outcome measure was the Modified Rankin Scale (mRS) score at 90 days, with secondary outcome measures including time metrics, mRS and National Institutes of Health Stroke Scale scores at 7‐day follow‐up, and hospitalization costs.ResultsOf the 2281 enrolled patients, 207 were eligible for t‐PA treatment, with 101 allocated to MSU care and 106 to EMS care. The percentage of patients achieving a favorable mRS score (0–2) at 90 days was 82.2% in the MSU group compared to 72.6% in the EMS group (p < .05). Median times from symptom onset to thrombolysis were 146 min in the MSU group and 204 min in the EMS group, while median times from ambulance alert to computed tomography (CT) completion were 53 and 128 min, respectively. Hospitalization charges averaged approximately $3592 in the MSU group and $4800 in the EMS group.ConclusionsOur findings indicate that 5G MSU care significantly reduces the time from symptom onset to stroke diagnosis and intravenous thrombolysis in patients with AIS, resulting in improved functional outcomes compared to EMS care. As China continues its deployment of 5G technology and other digital infrastructures, the adoption of 5G MSU care on a broader scale may eventually supplant traditional stroke treatment approaches.
