Acute Stroke Triage, Thrombectomy Selection, and Message Center Decision Support
AI clinical decision support spanning EMS identification of severe or large-vessel-occlusion stroke, routing to thrombectomy-capable or comprehensive stroke centers, prediction of futile recanalization risk after mechanical thrombectomy for patient selection and care planning, and EHR message center assistance for triaging prescription renewal, lab result, and symptom-related patient messages with chart context.
Business Blueprint
GROUNDEDAI decision support helps acute stroke teams assess futile-recanalization risk after mechanical thrombectomy and bring that risk estimate into clinical decision-making.
The Problem
In acute ischemic stroke caused by large vessel occlusion, mechanical thrombectomy is a primary treatment, but the likelihood of futile recanalization at 90 days post-treatment remains high; clinicians need a practical way to assess that risk for patients undergoing thrombectomy.
Neurology clinicians
They must assess futile-recanalization risk for acute ischemic stroke patients with large-vessel occlusion who undergo mechanical thrombectomy, where poor 90-day outcome despite recanalization remains a known concern.
Stroke care teams
They are managing acute ischemic stroke patients with anterior-circulation large-vessel occlusion after mechanical thrombectomy, where the primary outcome of concern is futile recanalization.
Cost of Inaction
Continued high likelihood of futile recanalization at 90 days post-mechanical thrombectomy without a deployed clinical tool to help clinicians assess that risk.
Process Fit
Diagnostic & decision supportAs-Is
Stroke teams treat large-vessel-occlusion ischemic stroke with mechanical thrombectomy while facing a persistent risk that recanalization will be futile at 90 days; risk assessment is a clinical judgment point rather than a consistently available AI-supported step.
To-Be
A clinician opens a clinical web application, reviews a patient-specific futile-recanalization risk estimate with explanation, and uses it as decision support for thrombectomy-related selection, counseling, and care planning while retaining final clinical accountability.

Systems Touched
Business Cycle
Upstream
- A defined acute stroke pathway for large-vessel-occlusion patients undergoing mechanical thrombectomy.
- Availability of the patient features needed to calculate and explain futile-recanalization risk.
Downstream
- More structured clinician assessment of 90-day futile-recanalization risk for patients considered for or treated with mechanical thrombectomy.
- Better-supported discussions about prognosis, care planning, and escalation decisions for high-risk patients.
Value Evidence
- Futile-recanalization prediction performanceIMPROVED
accurately predicting FR in both internal (area under the curve (AUC)=0.915) and temporal (AUC=0.930) validations.
- Clinical availability of the risk-assessment toolIMPROVED
Adoption Journey
LEVEL 1 — QUICK WIN
Gate: Prove value on retrospective and temporally separated thrombectomy cohorts.
Outcome: The stroke team gains confidence that the risk signal is strong enough to review in a controlled clinical setting.
LEVEL 2 — STANDARD
Gate: Prove clinicians can use the web application at the point where futile-recanalization risk is reviewed.
Outcome: Risk assessment becomes an available clinical decision-support step rather than a research-only result.

Risk & Governance
Clinical overreliance on an AI risk score in high-stakes stroke treatment decisions.
Posture: Keep the tool as decision support only: clinicians must review the risk estimate and remain accountable for thrombectomy selection and care planning.
Model performance may not hold as patient mix, timing, or treatment practice changes.
Posture: Monitor outcomes and periodically compare current performance with the validated internal and temporal performance before broadening use.
Clinicians may not trust or act on an unexplained risk estimate.
Posture: Present the score with patient-level explanation and require documentation of how it was considered in the clinical decision.

How it works
AI runs the first three steps autonomously.
Humans own every decision.
The system gets smarter each cycle.

Real-World Use Cases
AI-assisted EMS routing for suspected large-vessel-occlusion stroke
When someone may be having a severe stroke, the system helps decide whether the ambulance should go straight to a hospital that can remove the clot or first go to a closer hospital for initial treatment and transfer later.
AI severity triage to identify stroke patients needing comprehensive stroke center resources
The system estimates whether a possible stroke is severe enough that the ambulance should consider routing the patient to a hospital with advanced stroke capabilities.
Explainable ML web app to predict futile recanalization after mechanical thrombectomy
A web tool uses patient data to estimate whether reopening a blocked brain artery after stroke treatment is unlikely to lead to good recovery, and shows doctors which factors drove the prediction.
