Stroke Outcomes

The performance measures in the tables below were developed by the Joint Commission in collaboration with the American Heart Association/American Stroke Association (AHA/ASA) and show how Michigan Medicine compares against state and national benchmarks as well as American Heart Association recommendations.

Comparison of Median Time to Give tPA Treatment

Timing is critical for treating patients with ischemic stroke. The table below compares Michigan Medicine's median time of 34 minutes to give tPA (clot-busting medication) treatment to the American Heart Association goal (less than 60 minutes); the national benchmark of 40 minutes; and the Michigan Benchmark of 45 minutes.

The chart also shows Michigan Medicine's percentage of eligible patients treated within 60 minutes of arrival (100%) as compared to the AHA goal (85%), national benchmark (89.4%) and Michigan benchmark (82.6%).
