Patients experiencing stroke are often transferred between hospitals to access advanced care or resources. In 2021, the Wisconsin Coverdell Stroke Program surveyed the Stroke Coordinators of Wisconsin to better understand transfer patterns between hospitals for patients experiencing stroke. Our Stroke Transfer Map visualizes that survey data to help partners gain insight and take action to improve stroke care.
Our Stroke Transfer Map can assist partners in the following ways:
- Hospitals and emergency medical services providers can identify where their stroke patients are frequently being transferred.
- Statewide stakeholders can help the Wisconsin Coverdell Stroke Program identify gaps in stroke care accessibility to hospitals and emergency medical services.
- Regional stroke coordinators can identify jurisdictions where stroke service may be inadequate and communicate with policymakers.

Understanding our data: What does this map mean?
Hospitals are represented on this map as points. The larger points are “hub” hospitals, and the smaller points are “spokes”. Spoke hospitals are community hospitals where stroke patients initially arrive. Hub hospitals are those where a stroke patient is transferred to when requiring a higher level of care, sometimes referred to as tertiary centers. Hospitals can receive stroke certifications from The Joint Commission or the Det Norske Veritas. Hospital stroke certification types are shown as different colors on the map, and include:
- Comprehensive stroke center (CSC)
- Primary stroke center (PSC)
- Acute stroke ready hospital (ASRH)
The lines on this map represent stroke patient transfers between hospitals. The lines join hospitals to show connections where spoke hospitals transfer stroke patients 25% or more of the time to hub hospitals. Driving distances and times were calculated using Esri's Network Analyst extension and the Street Smart Data Compression (SDC) Network Dataset in ArcMap 10.7. These data do not reflect emergency medical services driving distances or times. Please note that some stroke transfers occur by air. This map does not reflect those distances and times.
About our data: How did we measure this?
Wisconsin Coverdell Stroke Program staff surveyed eight stroke coordinators across the five Wisconsin Public Health regions. Stroke coordinators identified hospitals where stroke patients were transferred to 25% or more of the time. Data collection and review occurred December 2020 through March 2021. Wisconsin Coverdell Stroke Program staff and stroke coordinators will update this map annually to reflect transfer patterns.
