CAUTION: HFA II-i series system software 5.x and the 15.0 system software release for
HFA II instruments create a different database structure than previous versions that is
not fully compatible with previous software releases.
WARNING: Every patient has an identifier that consists of Name, Date of Birth, Patient
ID, and Issuer of ID. To avoid unintentional automatic merging of patient records,
VERIFY a unique combination of Name, Date of Birth, Patient ID, and Issuer of ID
exists when patients are copied, transferred, retrieved from an archive, or restored
from a backup. There is no way to separate the combined records of erroneously
merged patients. Automatic merging of patient records occurs when a patient exists
in the local database with the EXACT SAME Name, Date of Birth, Patient ID, and
Issuer of ID as a patient that is copied, transferred, retrieved from an archive, or
restored from a backup.
For example, consider the following scenario:
Patient A: This patient is currently on the local HFA database and was automatically
assigned a unique Patient ID by the instrument because it was a blank field prior to a
software upgrade to V5.x software or during an import to the HFA through a copy,
transfer, retrieval from archive, or a restore from backup.
