Demonstration: Creating a Custom Schema

In this demonstration, you create a custom schema based on the HL7 version 2.3 schema. You will customize a single message structure, ADT_A01, to include a Z segment (ZWG) which contains information regarding the wing of the hospital to which the patient is assigned. The structure of the ADT_A01 message type in the custom schema will be defined by the new ADT_A01 message structure. Here is a summary of the important details:

  • New Schema: TutorialSchema

  • Base Schema: 2.3

  • Customized Message Types(Structures): ADT_A01(ADT_A01)

  • Customization: Addition of trailing ZWG segment.
