HL7 Configurator

HL7 (Health Level 7) is a standard for electronic data interchange in healthcare environments, with an emphasis on hospitals. HL7 refers to the highest level of the OSI, or Open System Interconnection, model from the ISO, or International Standards Organization. In the OSI conceptual model, communications software and hardware functions are separated into seven layers, or levels. The HL7 standard is primarily focused on the issues that happen within the seventh layer, or application level.

HL7 does not specifically conform to ISO-defined elements of the OSI seventh level. It also does not specify a set of ISO approved specifications to occupy levels 1-6 under HL7's abstract message specifications. HL7 conforms to the conceptual definition of an application-to-application interface.

The HL7 standard addresses the interfaces among various systems that send or receive ADT (Admissions, Discharge, and Transfer) data, queries, orders, results, and billing data. For more information about this standard, refer to Health Level Seven: An Application Protocol For Electronic Data Exchange In Healthcare Environments, available from Health Level Seven, Inc.

Variants

Using the HL7 Configurator, you specify HL7 variants as necessary for a given connection or site.

By creating variants, you add vendor-specific data to the standard definitions. For example, you can create Z segments or modify message definitions.

Variants are based on the standard message layouts.

Add or modify fields, segments, and messages within these specific variants.

Note:  v3 CDA 1.0 and 2.0 do not automatically display as existing variants. CDA is an XML-based message and is supported by importing the schemas/DTDs with the XML Package Manager.
