Meet Our Stroke Care Experts

We started with our own stroke program in Baltimore, Maryland, then identified the need for expertise in developing stroke programs nationally and internationally. We take the best evidence-based practice and help adapt it to the local environment for maximum efficiency and efficacy.


Dr. Victor Urrutia

Victor C. Urrutia, M.D.

Victor Urrutia is a professor of neurology at the Johns Hopkins University School of Medicine. He serves as director of the Comprehensive Stroke Center at The Johns Hopkins Hospital and is a medical director with Johns Hopkins Medicine International. He is founder and director of the Global Center for Organized Stroke Care and Johns Hopkins Medicine International stroke program consulting.

Dr. Urrutia’s interests are acute treatment, stroke prevention and improving delivery of care. He led the organization of the Johns Hopkins Hospital Comprehensive Stroke Center, of which he has been the medical director since 2010, as well as the Stroke Prevention Clinic (2011). As the chair of the Stroke Quality Improvement Committee at the Maryland Institute of Emergency Medical Services and Systems, Dr. Urrutia oversaw implementation of interhospital transfer guidelines, adoption of the LAMS score by emergency medical services personnel and creation of a quality improvement process for interhospital transfers.

He has consulted on and conducted mock stroke center surveys that led to successful accreditation of primary and comprehensive stroke centers in New York, Utah and Maryland.

Internationally, Dr. Urrutia works with Johns Hopkins Medicine International as medical director for the affiliate in Panama, and has consulted on and led the organization of stroke programs in Colombia, Panama (both achieving Joint Commission International certification) and Bermuda; he is currently working on projects in Saudi Arabia and the United Arab Emirates. He led the creation of and manages the Bermuda Telestroke program, an international collaboration to provide acute stroke expertise to Bermuda.

Dr. Urrutia’s clinical trials include SAIL ON (NCT01643902), a trial of intravenous tPA for wake-up stroke up to 4.5 hours from awakening and OPTIMIST (NCT02039375), a novel clinical monitoring protocol for patients treated with intravenous alteplase, which is now launching into a multinational stepped wedge cluster randomized clinical trial, of which he is the deputy chair of the steering committee and principal investigator of the U.S. region. Dr. Urrutia led the Maryland Acute Stroke EMS Routing Pilot Study that resulted in a change in emergency medical services routing policy in Maryland, by which patients suspected of large artery occlusion are transported directly to hospitals capable of providing thrombectomy treatment.

Mona Bahouth

Mona Bahouth, M.D., Ph.D.

Mona Bahouth is an assistant professor of neurology and medical director of the brain rescue unit at The Johns Hopkins Hospital. She has experience in system science, outcomes research and the integration of clinically meaningful technologies into stroke care. She received her medical degree from the University of Maryland School of Medicine and neurology training at the Johns Hopkins University School of Medicine, where she completed her stroke fellowship. She is passionate about systems of stroke care and delivering the highest quality, high-value care to all patients who have had a stroke.

Dr. Bahouth has designed and led numerous acute stroke clinical trials. Her clinical research agenda focuses on understanding physiological readiness for activity after stroke, team science and techniques to improve recovery after stroke in the early treatment period. She has been funded by the National Institutes of Neurological Diseases, National Institutes of Aging, Fogarty International Center and the American Heart Association. Through innovative systems of care and research, we can do better to eliminate the mark of stroke.
