ADT^A48
ADT/ACK - Change alternate patient ID
Patient Administration
Event A48 has been retained for backward compatibility only, corresponding with PID-4 - alternate Patient ID-PID, which is also retained for backward compatibility. From V2.3.1 onwards, event A47 (change patient identifier list) should be used instead. A change has been done at the alternate patient identifier level. That is, a PID-4 - alternate patient ID-PID has been found to be incorrect and has been changed.
An A48 event is used to signal a change of an incorrectly assigned alternate patient identifier value. The "incorrect source alternate patient ID" value is stored in the MRG segment (MRG-2 - prior alternate patient ID) and is to be changed to the "correct target alternate patient ID" value stored in the PID segment (PID-4 - alternate patient ID-PID).
