The process may be summarised as follows:

  1. Data is collected from the clinical information system to create and saved as an encrypted extract file
  2. Data is de-identified via the FAT CAT process G-tags are assigned to the data(Filtering and Anonymisation Tool for CAT)
  3. The de-identified data is tagged with a unique and encrypted code that can be matched with a geographical location in PAT CAT
  4. Data is aggregated .in PAT CAT
