Resumen

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.

Descripción detallada

Outcomes for stroke patients are closely tied to how fast they receive treatment. 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. In the DTAS workflow stroke patients are diagnosed and treated in the interventional suite without interruption. The Cone-Beam CT (CBCT) capabilities of the interventional X-ray system are utilized to perform triage, directly followed by stroke treatment. The primary objective of the WE-TRUST study is to demonstrate that the DTAS triage workflow involving CBCT results in superior patient outcome in ischemic stroke patients with confirmed Large Vessel Occlusion as compared to the conventional CT/MR triage workflow. The WE-TRUST study will be running in 16+ sites to enroll 500+ patients globally.

Edad mínima: 18 YearsSexo: ALL

Criterios de inclusión

Subject is 18 years of age or older, or of legal age to give informed consent per state or national law.
Baseline NIHSS score obtained prior to randomization must be equal or higher than 10 points.
Subjects with no significant pre-stroke functional disability (modified Rankin scale 0 - 2).
Subjects suspected of acute ischemic stroke with an estimated arrival time at a stroke center (clinical investigational site participating in this study) \< 6 hours from symptom onset OR wake-up stroke with time last known well of \< 12 hours and symptoms discovered within 6 hours from arrival time at a stroke center. Symptom onset is defined as point in time the patient was last known well (at baseline).
Informed consent obtained from patient or his or her legally designated representative (if locally required).
Angiography suite immediately available.
Endovascular treatment team immediately available (Neurologist, Neurointerventionalist, Anesthesiologist, Nursing, Technicians as per local standard practice)

Criterios de exclusión

Unlikely to be available for 90-day follow-up (e.g. no fixed home address, visitor from overseas).
Known hemorrhagic diathesis, coagulation factor deficiency, or oral anticoagulant therapy with INR \> 3.0
Known baseline platelet count \< 30.000/μL
Baseline blood glucose of \< 50mg/dL (\< 2.78mmol/l)
For patients receiving thrombolysis: severe, sustained hypertension (SBP \> 185 mm Hg or DBP \> 110 mm Hg). Note: If the blood pressure can be successfully reduced and maintained at the acceptable level using AHA/ASA guidelines recommended medication (including IV antihypertensive drips), the patient can be enrolled.
Patients from a transfer center (Primary Stroke Center) with a CT/MR that is not required to be redone in the Comprehensive Stroke Center as per discretion of the physician or per local standards (e.g. CT/MR less than 90 minutes old).
Patients in coma (NIHSS item of consciousness \>1) defined as totally unresponsive; responding only with reflexes or being areflexic (Intubated patients for transfer could be randomized only in case an NIHSS is obtained by a neurologist prior transportation).
Patients with extreme vomiting
Patients that are extremely agitated
Seizures at stroke onset which would preclude obtaining a baseline NIHSS
Serious, advanced, or terminal illness with anticipated life expectancy of less than one year.
Patients acquired stroke while in-hospital
History of life-threatening allergy (more than rash) to contrast medium
Cerebral vasculitis
Patients with a pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations, mRS score at baseline must be ≤2. This excludes patients who are severely demented, require constant assistance in a nursing home type setting or who live at home but are not fully independent in activities of daily living (toileting, dressing, eating, cooking and preparing meals, etc.)
Patients with unstable clinical status who require emergent life support care
Any condition that, in the judgment of the investigator could impose hazards to the patient if study therapy is initiated or affect the participation of the patient in the study.
Subject participates in a potentially confounding drug or device trial during the course of the study.
Woman of childbearing potential who is known to be pregnant on admission.
Subject is Philips employee or their family members residing with this Philips employee.
