|The geo-coding process is achieved by the following steps:
To ensure patient privacy, all mapping of patient data in PAT CAT is of aggregated data, individual patients are never shown. In fact it requires at least five patients to be present within a map segment (SA2) for any information to be shown.
|The data de-identification and geocoding process occurs through the De-identify Dataset / Add GTAGs functionality included in CAT4.
When an extract is run through the De-identify Dataset / Add GTAGs functionality;
de-identified data refers to patient clinical data (e.g. diagnosis, measurements, pathology etc) that does not contain information that can be used to reverse identify the patient. De-identified data is permissible for use where is is not practicable to obtain informed consent for use of data. PEN CS has provided tools within CAT4 that can be run by the practice to create a de-identified patient data set. These tools are collectively known as FAT CAT, the Filtering and Anonymisation Tool for CAT. They are incorporated into CAT4.
FAT CAT ensures that the de-identified data extract produced by Classic CAT strictly adheres to the National Privacy Principles.
Classic CAT de-identified data files that have been through the FAT CAT process are tagged as “certified”. PAT CAT recognises FAT CAT “certified” data files and these are the only data files that PAT CAT will import and display and rejects the files that were not FAT CAT "certified".
