New Mobile Stroke Unit Programs Aim to Improve Outcomes

Now well-established throughout Europe, mobile stroke unit (MSU) programs are in the early stages of development in the United States. The concept aims to improve outcomes by bringing diagnostic capabilities and clot-busting care to the patients experiencing stroke, thereby reducing the time to treatment. In October, New York Presbyterian/Weill Cornell Medical Center in New York became the first medical center on the East Coast to deploy an MSU, and in July, the University of Tennessee College of Medicine in Memphis deployed a first-of-its-kind MSU that is larger and more robust than other MSUs currently in use. In the first month of operation, the MSU in New York responded to 29 calls and brought 12 patients to the hospital with suspected strokes. Two of these patients received tissue plasminogen activator in the field and both made full recoveries by the next day. The MSU deployed in Memphis is larger and carries more sophisticated diagnostic equipment than other MSUs. The program also replies on doctorally prepared, vascular neurology fellowship-trained nurse practitioners, instead of relying on telemedicine connections to external experts. Now operating with the assistance of grant funding, leaders of both programs hope that strong outcomes will prove convincing to hospitals and prayers, although the U.S. healthcare model complicates the establishment of a reimbursement structure for MSUs.
