Stroke Treatment in Critical “Golden Hour” More Likely in Mobile Stroke Units

March 25, 2021
By Nancy Melville YORK, Me -- March 24, 2021 -- Patients who receive stroke treatment in a mobile stroke unit are significantly more likely to receive potentially life-saving clot-buster treatment, to receive treatment within 1 hour of stroke onset, and to achieve a full recovery than those treated in a standard ambulance, according to a study presented at the 2021 Virtual International Stroke Conference (ISC). “More widespread deployment of mobile stroke units may have a major public health impact on reducing disability from stroke,” said James C. Grotta, MD, Clinical Institute for Research and Innovation at Memorial Hermann, Texas Medical Center, Houston, Texas. “Although mobile stroke units are costly to equip and staff, they reduce the time to treatment. We also expect that more treatment via mobile stroke units can reduce the need for downstream utilisation of long-term care.” The study, part of the ongoing Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit (BEST-MSU) study, involved 1,047 patients who had experienced an ischaemic stroke and were transported to the emergency department either in a mobile stroke unit (n = 617) or by standard emergency medical services (n = 430). The patients, all eligible for treatment with tissue plasminogen activator (tPA), were treated between 2014 and 2020 at 7 centres around the United States. Although nearly all (97.1%) patients transported in the mobile stroke unit who qualified for tPA received the treatment within 4.5 hours of symptom onset, the rate was only 79.1% among those transported in a standard ambulance (PP = .002). The odds of achieving a complete recovery, with a mRS of 0 to 1 after 3 months, was 2.43 in favour of patients treated by the mobile stroke unit (P[Presentation title: Benefits of Stroke Treatment Delivered by a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services (BEST-MSU Study).
