BT Clinical Computing aims at structuring the existing data of medical and hospital information systems into a SNOMED CT repository from where the data can be reused for secondary coding (ICD10), data extraction for Patient Summary, Personal Health Record and clinical research. The intelligent SNOMED CT-repository can feed decision support systems and business intelligence. Structured and unstructured source data are normalised to postcoordinated SNOMED CT expressions and are converted from there to multiple targets (ICD, registries, clinical trials).
