Clinical trial Recruiting at 2 sites Observational Ages 18 and up

AI-based tools to help diagnose, treat and predict stroke outcomes across multiple hospitals

Official title: Unleashing a CoMprehensive, Holistic and Patient Centric Stroke Management for a Better, Rapid, AdvancEd and PersonaLised Stroke Diagnosis, TreAtment and Outcome Prediction (UMBRELLA) - Prospective Clinical Study

Run by Hospital Universitari Vall d'Hebron Research Institute · NCT07924371 · Data updated 2026-11-12

This study tests AI-powered tools on real-world stroke patients to see if they can improve pre-hospital triage, diagnosis, and outcome prediction while data stay securely within each hospital.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with a clinical suspicion of acute stroke or TIA who can provide informed consent or have a legally authorized representative.

Probably not a fit

Patients not fitting into the specific sub-studies or whose data do not contribute to the AI models may not directly benefit.

What this trial studies

This is a multicentre, prospective observational study involving seven university hospitals across six European countries. It collects routine clinical, imaging, lab, ECG, and patient-reported data, then harmonises these data to the OMOP Common Data Model. AI models are trained and validated using a federated learning approach so patient data never leave the hospital sites. A retrospective data harmonisation phase precedes prospective validation to test the models on new, independently collected data. The study includes sub-projects focused on pre-hospital triage, rapid reperfusion decisions, emergent intracerebral hemorrhage management, and other stroke-related outcomes.

Why it matters

Potential benefit: If successful, the AI tools could streamline stroke workflows, improve triage accuracy, and enhance treatment decisions without compromising patient privacy.

How similar studies have gone: Federated, data-harmonised AI approaches in stroke care have shown promise in earlier studies, though this exact multicentre federated setup is innovative.
