HL7 Message Types: Challenges

From HL7 ADT messages containing patient demographics, to HL7 ACK containing protocol acknowledgement information, HL7 messages come in many different types, each containing its own unique set of segments and fields. As they move through your healthcare ecosystem, each type of message requires its own specific handling procedure to ensure that the data is routed, received and sent correctly from one system to the other.
