Petznick Stroke Center

About Our Program

At the Petznick Stroke Center, we are committed to providing excellent care, informing the community about prevention through control of risk factors, and finding new ways of treating and preventing stroke through research.

Barrow Neurological Institute at Dignity Health St. Joseph’s Hospital and Medical Center has one of the most experienced and comprehensive stroke programs in the country, caring for more stroke victims than any other center in the southwestern United States.

Barrow is the major stroke research center in the Southwest. Our team conducts more clinical stroke treatment and prevention research trials than any other institution in the region.

In addition, the Petznick Stroke Center has met the rigorous standards for designation as a Comprehensive Stroke Center by the Joint Commission in partnership with the American Heart Association and the American Stroke Association.

The Petznick Stroke Center is nationally certified by The Joint Commission. Additionally, we hold a Primary Stroke Center certification from the American Heart Association/American Stroke Association. 

This certification recognizes hospitals with state-of-the-art infrastructure, experienced staff with unique education, and competency standards to receive and treat patients with strokes. It is a testament to our ability meet stroke center standards and requirements. These include advanced imaging capabilities and 24/7 availability of subspecialized treatment.  

Our Stroke Center also received 2020 Get With The Guidelines Awards from the American Heart Association/American Stroke Association. They included the Gold Plus Quality Achievement, Target: Stroke Honor Roll, and Target: Stroke Advanced Therapy awards. These top honors highlight our adherence to achievement measures and our commitment to reducing treatment times.

We also voluntarily enter our clinical data into the Get With The Guidelines public reporting website and report outcomes for cases and procedures at our hospital. Our dedication to quality improvement and transparency by publicly reporting our outcomes sets us apart from other stroke centers.

Mobile Stroke Unit

Barrow is home to the first mobile stroke unit in the country to operate around the clock in a city with a population greater than 1 million. We launched the Barrow Emergency Stroke Treatment Unit in 2017 in partnership with the Phoenix Fire Department. Their 911 dispatchers deploy the unit whenever they receive a call about a possible stroke within the unit’s response radius. 

Our mobile stroke unit is staffed with a trained stroke team and functions like an emergency room on wheels. It is equipped with a portable lab, computed tomography (CT) scanner, and clot-dissolving drugs. The stroke team connects with an on-call vascular neurologist via telemedicine and can begin treatment on scene.

If it hadn’t been for Barrow Neurological Institute, I probably wouldn’t be sitting here doing this good right now.

I was looking at a computer laptop at a face of a neurologist that was asking me life-saving questions. They got me to the Barrow Neurological Stroke Center and took care of me. Within minutes, I was in a CAT scan and got a life-saving blood-thinner medication. I didn’t realize until later how serious it was. Thank God I was in their hands.
