Stroke Outcomes

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

Comparison of Median Time in Minutes to Give Alteplase Treatment

Timing is critical for treating patients with ischemic stroke. The table below compares Sparrow Hospital’s median time of 48 minutes to give Alteplase (tPA) treatment to the American Heart Association goal (less than 60 minutes); the national benchmark of 43 minutes; and the Michigan Benchmark of 45 minutes.

The chart also shows Sparrow Hospital’s percentage of eligible patients treated within 60 minutes of arrival (89%) and 45 minutes of arrival (42%) as compared to the AHA goal (75% and 50%) national benchmark (84.2% and 56%.) and Michigan benchmark (82.5% and 51.9%).

Measure American Heart Association Goal Sparrow National Benchmark 2019 Michigan Benchmark 2019
Alteplase (clot busting medication) treatment Median time in minutes <60 minutes 48 43 45
Percentage of eligible patients treated within 60 minutes of arrival 85% 89% 84.2% 82.5%
Percentage of eligible patients treated within 45 minutes of arrival 75% 42% 56.0% 51.9%
Percentage of eligible patients treated within 30 minutes of arrival 50% 22% 21.7% 17.4%


 2019 Procedure Outcomes

Those who are not getting better with clot-busting medication can be considered for minimally invasive procedures to remove the clot from clogged vessels.

The procedure outcomes below show Sparrow Hospital's percentage of major complications as compared to the Joint Commission target for four stroke-related procedures:

  • Symptomatic carotid endarterectomy and carotid artery stenting: 1/73 = 1.4% as compared to Joint Commission target of <6%
  • Asymptomatic carotid endarterectomy and carotid artery stenting: 2/53 = 3.8% as compared to Joint Commission target of <3%
  • Diagnostic angiogram: 1/178 = 0.6% as compared to Joint Commission target of <1%

2019 Procedure Outcome

Procedures Complications Patients % TJC benchmark
2019 Asymptomatic Carotid Stent and Carotid Endartectomy 2 53 3.8% <3%
2019 Symptomatic Carotid Sstent and Carotid Endartectomy 1 73 1.4% <6%
Diagnostic Angiogram 1 178 0.6% <1%
