This course is part of the Iguana Training Series, a set of private courses that cover an array of interfacing concepts in Iguana. The exercises in this course presume you have completed the Working In Iguana course, which leads you through the process of building three channels that take in and send out HL7 messages.

 

HL7's version 2 messaging standard continues to play a major role in health care interoperability. In this course, we will learn how to build basic HL7 interfaces.

Some of the concepts we will cover include:

  • How do we parse incoming data and what is┬áthe role of .vmd files in parsing HL7 messages?
  • How do we perform mapping and transformation?
  • How do we filter messages?
  • How do we troubleshoot errors?
  • What are some design best practices to consider?
  • How do we tie in monitoring and alerting to interface logic?
