The Medical Records Chart processor validates incoming chart data to ensure that duplicate records are not created. When a message is received which prompts the creation, updating, or merging of a chart, the MRN and MPI of the incoming message are checked against existing charts. If the MRN in the incoming message matches the MRN of an existing chart but the MPIs associated with the two do not match, the incoming chart data is determined to be duplicate, and rejected.
If an incoming message has an MRN which matches an existing chart but includes no MPI at all, the charts are merged without error.
The HL7 Listener can be configured to send one of the following acknowledgment codes in response to receiving a duplicate chart:
-
AR (Rejected)
-
AE (Error)
-
AA (Success)
By default, the HL7 Listener sends an acknowledgment code of AR (Rejected) when a duplicate chart is received. This ensures that the sending application is aware that the message failed and was not processed. However, an AR code may interrupt your system's normal functioning. If you are aware that duplicate charts are being encountered and rejected and don't want the interruption caused by an AR code, you can configure the HL7 Listener to respond to duplicates with an AE or AA code instead.
If you select AA (Success), a message is displayed warning that sending applications will not be aware that their messages have failed. However, error report emails will still be sent if configured, and the failure will be logged.
To configure the acknowledgment code for import failures:
- Select a setting under If Chart Processor detects duplicates, respond with MSA.1 set to.
