Looking for Iguana v.5 or v.6? Learn More or see the Help Center.
Rather than thinking of discrete HL7 messages such as ADT^A01, ADT^A03 or ADT^A08, it can be much more useful to group several distinct HL7 messages that you are receiving into one logical message. This can be done through the use of regular expressions to match the codes that you are expecting. For more information, see Using Regular Expressions. |
