The Deducted Patient Record in Consultation Manager
For patients whose records have transferred to a new practice, there is a Journal entry of Read code 92 Patient de-registration. The patient's registration status remains as permanent until deducted in the usual way. You could add a manual reminder that the patient's records have been transferred.
The Read code of 92 allows you to do regular searches for patients whose records have been transferred recently (Search for patients with transferred records).
