La Princesa had an ambitious mandate: participate in the European Health Data Space by making its clinical imaging datasets available to researchers and institutions across Europe. The challenge was doing it without compromising patient privacy or moving sensitive data outside the hospital's own walls.
TietAI built the entire infrastructure on-premise, inside the hospital network. Hydra Platform sits across two hospital servers, ingesting radiology studies directly from the PACS system, applying clinical-grade anonymisation, and transforming the data into the OMOP common data model. A live EHDS metadata catalog then makes those datasets discoverable across the European Health Data Space, without any patient data ever leaving La Princesa.
All AI inference runs on local models. There are no external cloud dependencies, no third-party AI providers, and no compliance exceptions to negotiate. The hospital's data sovereignty is absolute.
