Time has a significant impact on the severity of patient outcomes in stroke. The earlier the patient is conclusively diagnosed and receives treatment, the more likely they are to make a meaningful recovery from the devastating effects of the disease.

By bringing the hospital to the patient, California’s first mobile stroke unit (MSU) provides unparalleled access to hyperacute diagnosis and treatment of stroke prior to hospital arrival. Since its launch in 2017, the UCLA Health MSU program, part of the UCLA Arline and Henry Gluck Stroke Rescue Program, has expanded to include collaborations with six Los Angeles County fire departments across three alternating geographic sites, administering clinical coverage of acute stroke dispatches 12 hours per day, six days per week.

Best Hospitals Neurology & Neurosurgery

The MSU is a specialized ambulance that offers highly advanced clinical care in the prehospital setting. It is staffed by a vascular neurologist, either in person or by telemedicine; critical care nurse; firefighter paramedic; and a computed tomography (CT) technologist. The MSU has resources for rapid turnaround laboratory testing as well as CT scan technology, enabling the examination of brain tissue and brain blood vessels in the vehicle prior to arrival at the hospital. After the CT scan demonstrates whether stroke symptoms are caused by vessel blockage and lack of blood flow or, alternatively, bleeding into the tissue of the brain, patients can be quickly treated with brain and lifesaving medications in the MSU and routed to the most appropriate level-of-care stroke center.


UCLA Health's mobile stroke unit is granted accreditation by the Intersocietal Accreditation Commission for its CT scanner

UCLA Health's Mobile Stroke Unit is the second program to obtain accreditation from the Intersocietal Accreditation Commission (IAC) and currently the only unit operating that holds the accreditation. Congratulations to all services and departments that helped support our successful inaugural accreditation.

Accreditation by IAC indicates that UCLA Health's Mobile Stroke Unit has undergone an intensive application and review process and is found to be in compliance with the published Standards, thus demonstrating a commitment to quality patient care in CT. Comprised of a detailed self-evaluation followed by a thorough review by a panel of medical experts, the IAC accreditation process enables both the critical operational and technical components of the applicant facility to be assessed, including representative case studies and their corresponding final reports.
