Electronic health record systems are often closed, proprietary and contain incomplete and unstructured data. The result is that the wealth of information potentially available within health records is often inaccessible and underused. CogStack is an information retrieval and extraction platform which implements best-of-breed enterprise search, natural language processing, analytics and visualisation technologies to unlock the health record and assist in clinical decision making and research.

CogStack implements new data mining techniques within NHS Trusts – specifically, the ability to search any clinical data source (unstructured and structured), and Natural Language Processing applications developed to automate information extraction of medical concepts. This project will use CogStack and perform a detailed analysis of patient pathways and outcomes of patients with neurological disorders.
