Practice A to Practice B to Practice C
As patients move about, they can transfer from practice A to practice B and then on to practice C. This has an implication for degraded records. It may well be that practice C receives records that were previously degraded when practice B received them. Looking on the Import Summary tab displays Item was previously downgraded in the scenario.
See Next step - review the record and What happens when the patient is not registered at the previous practice.
