The DebugIT project partners have united to tackle the fast emergence of resistances among pathogens, misuse and overuse of antibiotics. For infectious diseases DebugIT (1) detects patient safety related patterns and trends, (2) acquires knowledge and (3) uses this for better quality healthcare. The DebugIT project uses clinical and operational information from Clinical Information Systems (CIS) across the EU through the ‘view’ of a virtualized, fully integrated Clinical Data Repository. Highly advanced new text, image and structured data mining on individual patients as well as on populations will render valuable informational and temporal patterns of patient harm.
