If you ever need to look back to see how the record looked at a certain date you can do this in SystmOne.
Go to the top menu
Patient > Patient Locator
Type in the patient details
At the top is a button called ‘Audit Trail’
Click on that – type in the date that you want to view
And the record will be retrieved as it was on that date
This is a read only view in the audit trail view. As soon as you discard you are taken back to today.
