Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services (BEST-MSU Study), United States, 2014-2022 (ICPSR 39547)
The standard care of hospital or emergency department patients experiencing an acute ischemic stroke includes intravenously administered tissue plasminogen activator (tPA). Mobile stroke units (MSUs) are ambulances equipped with staff and a computed tomographic scanner that can allow for tPA to be administered more quickly. This comparative effectiveness trial examined clinical outcomes in stroke patients who received either an earlier diagnosis and treatment using an MSU or standard triage and transport by Emergency Medical Services (EMS). The sample included multicenter cohorts with randomized deployment weeks and blinded assessment of both trial entry and clinical outcomes.

Imaging tests, such as X-rays and MRIs, can help find health problems. When assessing how well the tests work, accuracy is important. But other benefits and harms, such as having pain from the test or relieving worry by knowing test results, may also matter to patients.
In this study, the research team wanted to learn what effects of imaging tests matter to patients.
