Door to CT Scan: Median Time

What are we measuring and why?

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. Timely administration of tPA is a critical intervention in treating ischemic stroke - an emergency that results from a blockage in the blood vessels of the brain. MGH tracks the amount of time it takes for IV tPA-eligible patients to receive brain imaging after their arrival to the Emergency Department (ED). This measure considers patients who arrive to MGH within 4.5 hours of their first stroke symptoms and receive tPA treatment.

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

In 2016, the median time from ED arrival to CT scan was 17 minutes for eligible stroke patients. Performance was higher than the median times for academic hospitals (14 minutes) and Massachusetts Primary Stroke Service (PSS) sites (15 minutes).

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 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 narrow the 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, common signals include sudden numbness or weakness of the face, arms, or legs, especially on one side of the body; confusion or trouble speaking/understanding others; difficulty seeing in one or both eyes; trouble walking, dizziness, or loss of balance/coordination; or, a 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.
