The Mass General Stroke Service
Mass General’s Stroke Service provides comprehensive care, including diagnosis, prevention and treatment, for patients with stroke and other cerebrovascular diseases.
What Are We Measuring?

Ischemic stroke, which account for about 87% of all strokes, occurs when a blockage in the blood vessels to the brain causes damage to brain tissue. Immediate treatment may minimize long-term disability and even death from a stroke.
How Are We Performing?
At Massachusetts General Hospital, we track several measures related to ischemic stroke, including:
IV tPA - Arrive by 2 Hour, Treat by 3 Hour
See the percentage of eligible stroke patients who receive tPA treatment (anti-clotting drugs) within 3 hours of the start of stroke symptoms (that is, the time they were last known well).
Door to IV tPA: Percent (%) within 60 Minutes
See the percentage of eligible stroke patients who were treated with tPA within 60 minutes of ED arrival.
Door to IV tPA: Median Time
See the percentage of eligible stroke patients who were treated with tPA within 60 minutes of ED arrival.
Door to CT Scan: Percent (%) within 25 Minutes
See the percentage of patients treated with tPA who received brain imaging within 25 minutes of ED arrival.
Door to CT Scan: Median Time
See the median time in minutes from ED arrival to administration of tPA for ischemic stroke patients.
30-Day Mortality Rates
See the percentage of ischemic stroke patients who died within 30 days of admission to the hospital, and the rates of stroke or death within the 30 days for patients that underwent a Carotid Endarterectomy (CEA) procedure.
