Stroke Quality Scores
An ischemic stroke occurs when the blood supply to the brain is blocked or severely reduced, depriving the brain of the oxygen it needs to work properly.
The quality scores below tell you how well hospitals in the Duke University Health System follow the guidelines set by the American Heart Association/American Stroke Association (AHA/ASA) in treating ischemic strokes.
90-day Thrombolytic Therapy (t-PA) Outcomes
Percentage of patients in the 0-3 range as measured by Modified Rankin Score (see explanation below)
Modified Rankin Score (mRS) measures how well a patient functions at a certain period after treatment. In this measure, the time period is 90 days.
The mRS score ranges from 0-6.
- 0 refers to someone who has returned to normal activity as if the stroke never happened.
- 3 refers to someone who requires some help to walk, such as with a cane or walker, but not with another person’s assistance.
- 6 refers to someone who has died in this time period.
0-3 mRS is considered a good outcome range.
Duke University Hospital | Duke Regional Hospital | Duke Raleigh Hospital | North Carolina Hospitals* | |

Average Number of Minutes from Hospital Arrival to Initiation of t-PA
The faster we treat you, the better your chance of a positive outcome and recovery. The NC hospitals figure indicates how we compare to our peers. The American Heart/American Stroke Association benchmark is 60 minutes.
Duke University Hospital | Duke Regional Hospital | Duke Raleigh Hospital | North Carolina Hospitals* | |

Carotid Endarterectomy
0% complication rate (30-day post-procedure stroke and death rate)
Carotid endarterectomy is a procedure to improve blood flow through a major blood vessel that feeds the brain. Your surgeon makes an incision in the neck to remove plaque clogging your artery. While all procedures have a risk, Duke University Hospital reports that in the past year no patient suffered a stroke or death in the 30 days following this procedure.
Time period: July 2017 - June 2018
