About We Trust Study

What is the WE TRUST study

The WE-TRUST Study is a multi-center randomized clinical trial to assess the impact of a ‘Direct to Angio Suite’ (DTAS) workflow on stroke patient outcomes.

In the DTAS workflow stroke patients are diagnosed and treated in the interventional suite without interruption.Triage imaging is usually performed in the CT/MR suite after which the patient is sent to the interventional suite for treatment. In DTAS approach/workflow the Cone-Beam CT (CBCT) capabilities of the interventional X-ray system are utilized to perform triage, directly followed by stroke treatment. The study will be running in 16 sites to enroll 500+ patients globally.

Primary objective:
To demonstrate that the DTAS triage workflow involving CBCT results in superior patient outcome (90 day mRS) in ischemic stroke patients with confirmed Large Vessel Occlusion as compared to the conventional CT/MR triage workflow.

Why was this study performed?

Outcomes for stroke patients are closely tied to how fast they receive treatment: Every 30 minutes delay before treatment reduces the chance of a good outcome by 14%*, and every hour of delay ages the brain by 3.6 years compared to a normally aging brain*.

Currently, when a possible stroke patient arrives at the Emergency Department, typically first a CT or MRI exam is acquired for stroke triage. In case of an ischemic stroke the patient is then treated in an interventional suite. Several studies have indicated that a Direct to Angio Suite (DTAS) workflow can reduce the time to treatment and improve patient outcomes. The WE-TRUST (Workflow optimization to rEduce Time to endovascular ReperfUsion in Stroke Treatment) study aims to provide the most comprehensive assessment to-date that the DTAS triage workflow involving CBCT results in faster treatment and thereby improved patient outcome.
