A History of Mobile Stroke Units and Review of Literature
Journal Title: American Journal of Interventional Radiology - Year 2018, Vol 2, Issue 9
Abstract
Using intravenous tissue plasminogen activator (IV tPA), improved functional outcomes are seen with earlier initiation of treatment. Recent studies have shown endovascular revascularization to be a revolutionary and effective treatment. There have been many initiatives focused on improving public education and awareness of stroke symptoms. The concept of a mobile stroke unit (MSU) was created as a way of bringing treatment to patients. Earlier CT scans, delivery of tPA, proper triage and on-scene goal-directed care were the primary goals with these units. It was thought that rapid implementation would shorten hospital stay and improve outcomes. The University of Saarland found a decrease of 41 minutes from stroke alarm to therapeutic decision when an MSU was used. A second trial found a decrease of 25 minutes in time to treatment, an increase in the rate of thrombolysis utilization, and no change in the rates of intracranial hemorrhage or 7-day mortality when an MSU was employed. In 2016, a Lancet article showed that 3 month modified Rankin Scale (mRS) and 3-month mortality were improved in MSU patients. Finally, starting thrombolytic therapy in the MSU was associated with higher probability of mRS of 0-3 but not an improved 3-month survival rate. Long-term results are thus far not available precluding an effective cost-benefit analysis. Many study results are not generalizable as they compare a single hospital system and specialized MSU team to conventional care delivered by a multiple healthcare systems. Future studies will target these limitations.
