Learn how stroke alert response at the facility was vastly improved after the kaizen event.

The Study

Recently, Sheridan's radiology department completed a Kaizen event to improve critical IV-tPA workflows in both the ER and radiology departments of a hospital. Periodic delays between the time when a stroke alert was called and when the final radiologist has signed off so that the ED can determine the appropriate tPA, posed an ongoing problem.


The team established standard time allotments for each step of the stroke alert process during the Golden Hour IV-tPA cycle. Visual representation of each step helped set benchmarks for the group.


Working with both departments, the Sheridan Radiology team identified communication issues and other opportunities for improvement. Tactical changes were then introduced to help streamline the process and reduce response times.


After the Kaizen event, stroke alert response at the facility was vastly improved.

  • The IV-tPA cycle time was reduced by 20%
  • Visual controls were also placed at the facility for daily use
