Door to CT Scan: Percent (%) within 25 Minutes

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 percent of IV tPA-eligible patients who arrive in the Emergency Department (ED) less than 2 hours from the time they were last known well and who receive brain imaging by CT scan within 25 minutes of their arrival.

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

In 2015, 29% of eligible stroke patients at MGH receive their CT scan within 25 minutes of ED arrival. This is lower than the average rates for Academic Hospitals and Massachusetts Primary Stroke Service (PSS) Hospitals, which were 37% and 39% respectively.

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. In 2009, MGH implemented an "ED2CT" pager notification, which alerts all members of the Acute Stroke Team to the arrival of an acute stroke patient in the ED. This system helps 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.
