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.

How does Iguana support different HL7 messages types?

Does your project involve sending and receiving multiple types of HL7 Messages? Or are you working with one specific type of message? In that case, you may find yourself looking for an easy solution to process HL7 messages. Developed by iNTERFACEWARE, Iguana is a data integration platform that allows you to easily transform the format, structure, and values of your HL7 messages. Whether your data is incoming or outgoing, Iguana allows you to manipulate any HL7 message type.
