Background: Research has demonstrated the sooner a patient is treated, the better the outcome. Midwest Stroke Action Alliance (MSAA) began sharing best practices among the Chicago Region area hospital stroke centers in 2007. As MSAA has become a more formal organization, following the ever changing guidelines has been a priority to ensure the outreach in the community matches the current clinical practice guidelines and certification requirements. As the bar has increasingly been raised, this group has consistently met those challenges by sharing barriers and action plans that have been developed across hospitals.

Methods: This poster will demonstrate retrospective analysis of patients from Q1 2013 through Q1 2016. The patients represent 35 hospitals in the Chicago regions (7, 8, 9, 10 and 11). Key areas of impact include increasing the percentage of patients receiving tPA in 60 minute or less and a brief look at 45 minutes or less and how pre-notification from EMS helps activate the stroke teams to treat quicker.

Results: In Q1 2013, pre-notification occurred in 64% of patients with resulting DTN times in <60 minutes 33% of the time. In Q12016, pre-notification increased to 73% with subsequent DTN times under 60 minutes occurring 75% of the time. Of note, in Q12013, there was a treatment rate of 6% in DTN <45 minutes, whereas in Q12016, this number rose to 32%.
