HL7 Transformation

In this tutorial, you will set up an Iguana channel with scripted transformation enabled. By definition, scripted transformation is a method of transforming one HL7 format to another. It is very fast and results in less mapping code if the transformation only involves changing a subset of the total fields. It is also a very useful application for building a utility to remove confidential data from a set of HL7 messages (e.g. patient name). This tutorial only shows a small sample of the capability of scripted transformation. For more information, see Scripted Transformation in the Chameleon section of the manual.

The focus of this tutorial is to show you how to remove a patient's name from the contents of the HL7 message using scripted transformation.

In this tutorial, you will:

• Acquire some sample messages;
• Set up the VMD file you need to perform scripted transformation in Chameleon;
• Send HL7 messages to a message filter; and
• Get the message filter (with scripted transformation enabled) to send the messages to two destinations (e.g. LLP client and to a file).

The resulting messages sent to the LLP client and to a file will have the Z-segments removed. In addition, the patient name fields will be replaced with the text string fff.
