For practices who don't agree sharing their de-identified data with the PHN but agree to share the PIP QI related, aggregated report only, PAT CAT provides a configuration option. This is configured on the 'Practices' tab, for full details see Enrol Practices in PIP QI
The settings for practices who only want to submit PIP QI related data will have to match the screenshot below - the 'Enrolled to PIP QI' needs to be ticked and the 'Submitting Data' unticked.
A practice configured as above in PAT CAT will be able to upload the data from CAT4 and PAT CAT will import the extract, create the PIP QI related reports and then delete the extract. No other reports will be available to the PHN, no other data will be stored or made available otherwise to the PHN.
