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.

A computerized tomography (CT) scan provides clinicians with insight into the type of stroke a patient is having and helps determine whether tissue plasminogen activator (tPA) should be given. While time from onset to imaging is important, the most critical metric is timely administration of the clot-dissolving drug tPA.

Massachusetts General Hospital tracks the percentage of IV tPA-eligible patients who receive brain imaging within 25 minutes of their arrival to the emergency department. This measure considers patients who arrive to Mass General within 4.5 hours of their first stroke symptoms and receive tPA.
