The researchers in the Informatics team based at Glasgow, Dundee and Strathclyde Universities have constructed linked data sets using routine healthcare data in Scotland to derive risk prediction models for the main health care associated infections - S.aureus bacteraemia, E.colibacteraemia and Clostridium difficile. For all three organisms there are now prototype risk factor analyses and risk prediction models. The implementation of these models in clinical practice is developing, and studies have taken place with practitioners on the most appropriate ways to incorporate the predictions into clinical practice. The team has also investigated delivery mechanisms for the risk prediction models through mobile phone applications, internet web pages and embedding within GP software.
