Quality Measures

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 E.W. Sparrow Hospital compares against state and national benchmarks as well as American Heart Association recommendations.

Timing is critical for treating patients with ischemic stroke. The table below compares E.W. Sparrow Hospital’s median time of 40 minutes to give Thrombolytic treatment to the American Heart Association goal (less than 60 minutes); the national benchmark of 45 minutes; and the Michigan Benchmark of 45 minutes.

The chart also shows E.W. Sparrow Hospital’s percentage of eligible patients treated within 60 minutes of arrival (95.2%), 45 minutes of arrival (81.2%), and 30 minutes of arrival (29.5%) as compared to the AHA goal (85%, 75%, and 50%) national benchmark (86.4%, 65%, and 22.9%) and Michigan benchmark (84.8%, 60.8%, and 31.6%).

Comparison of Median Time in Minutes to Give Thrombolytic Treatment
Measure American Heart Association Goal Sparrow 2022 National Benchmark 2022 Michigan Benchmark 2022
Thrombolytic (clot busting medication) treatment Median time in minutes <60 minutes 40 45 45
Percentage of eligible patients treated within 60 minutes of arrival 85% 95% 86.4% 84.8%
Percentage of eligible patients treated within 45 minutes of arrival 75% 81.2% 65% 60.8%
Percentage of eligible patients treated within 30 minutes of arrival 50% 29.5% 22.9% 31.6%

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 E.W. 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: 1/59 = 1.7% as compared to Joint Commission target of <6%
  • Asymptomatic carotid endarterectomy and carotid artery stenting: 1/46 = 2.2% as compared to Joint Commission target of <3%
  • Diagnostic angiogram: 1/176 = 0.5% as compared to Joint Commission target of <1%
2022 Procedure Outcome
Procedures Complications Patients % TJC benchmark
2022 Asymptomatic Carotid Stent and Carotid Endartectomy 1 46 2.2% <3%
2022 Symptomatic Carotid Stent and Carotid Endartectomy 1 59 1.7% <6%
2022 Diagnostic Angiogram 1 176 0.5% <1%
