Case Study: University Hospitals Sussex NHS Foundation Trust achieves zero-downtime healthcare data modernization with Pythian

University Hospitals Sussex NHS Foundation Trust unifies regional healthcare data with Pythian and zero downtime

University Hospitals Sussex NHS Foundation Trust faced a challenge when merging two regional healthcare trusts, handling 1.5 million annual patient visits. Their expensive, end-of-support legacy reporting platforms threatened reporting continuity and created unsustainable operational risk. UHSussex needed a scalable cloud architecture to unify regional data and reduce operating costs, requiring a solution with zero downtime.

Pythian executed a zero-downtime migration of the trust's core systems to Oracle Cloud Infrastructure. The solution involved exporting on-premises databases to Oracle Autonomous Data Warehouse, refactoring analytics on Oracle Analytics Cloud, and upgrading financial planning with Oracle EPBCS. Pythian's work eliminated tedious maintenance, put AI-powered insights into clinicians' hands, and rapidly onboarded 1,000 new trust users post-merger with zero operational downtime during cutover.
