Door to CT Scan: Median Time

What are we measuring and why?

A computerized tomography (CT) scan provides critical information on the type of stroke a patient is having, and helps clinicians determine whether tissue plasminogen activator (tPA) should be given. Timely administration of tPA is a critical intervention in treating an ischemic stroke, a stroke where a blockage in the blood vessels in the brain causes damage to brain tissue. MGH tracks the median time from Emergency Department (ED) arrival to initiation of brain imaging by CT scan. The median time is the time by which half of the patients have been scanned (lower times are better).

How are we doing and how do we compare to best practices?

In 2015 the median time at MGH from ED arrival to CT scan was 20 minutes for those patients last seen well within 3 hours. For this same time period, the median times for Academic Hospitals and Massachusetts Primary Stroke Service (PSS) Hospitals was 18 minutes each.

What are we doing to improve?

The MGH Acute Stroke Quality Task Force routinely monitors time from ED arrival to CT scan and shares data - both with internal team members and ambulance personnel - to drive improvement. MGH promotes advanced hospital notification by ambulance personnel, and now uses an "ED2CT" pager notification, which alerts all members of the Acute Stroke Team to the arrival of an acute stroke patient in the ED. These systems help to reduce time to CT scan and, most importantly, tPA treatment.

What can you do?

It is important to learn the signs and symptoms of a stroke. According to the American Stroke Association, these signs include sudden numbness or weakness of the face, arm or leg, especially on one side of the body; sudden confusion, trouble speaking or understanding; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, loss of balance or coordination; or, sudden severe headache with no known cause.

If you think you might be having a stroke, call 911. Patients who arrive by ambulance get treated faster.
