If you discover you have duplicate patient records, you can use the Merge Patients button to remove the duplicates and re-link all existing exam forms to a single patient ID. For example, assume there is a single patient with three separate records in the NRDR patient dictionary:
Patient ID 11111, has 2 exams in LCSR
Patient ID 22222, has 3 exams
Patient ID 33333, has 1 exam
