HL7 Data Feeds

CareEvolution relies on minimal lower layer protocol (MLLP) as the standard for transmitting HL7 v2 messages over TCP/IP connections within a network. The receiving system, HIEBus, will set up an HL7 v2 listener over an IP/Port that will be shared with the HL7 v2 sender. MLLP itself does not describe any security standards and thus it is a requirement to secure the transport over a VPN connection. VPN connectivity is a separate set up between the sending system and CareEvolution.

The CareEvolution HIEBus HL7 v2 listener receives the HL7 message and sends an ACK back if its stored correctly to the inbound processing queue. Failure to persist the message for any reason results in a NACK back to the sending system. Persisted messages are later processed in the order they were received and errors in processing are reported back to the sending source. The sending system is expected to send messages in the correct order as the last message received on a patient or encounter will be assumed to have the most recent and up to date information.
