This handbook provides a guide to implementing HL7 Pathology messaging between pathology providers and health service providers in Australia using the HL7 Version 2.3.1 protocol.

Scope

This Handbook provides sufficient detail and discussion for the implementation of an HL7 based system for pathology messaging. It is intended that it be used as an implementation guide in conjunction with HL7 Version 2.3.1 and AS 4700.2-2004.
Pathology messaging implementation comprises both orders and results.
The guidelines are presented in three stages:
(a) Overview of HL7 structure and operation.
(b) Discussions on issues relating to pathology messaging in Australia.
(c) Detailed definition of HL7 message structures and segments.
The guidelines clarify the way a particular situation should be interpreted or handled. Implementers must adhere to the field definitions of AS 4700.2-2004. However, this guide describes methodologies and field structures and ways in which the content can be developed.
With regard to the actual content of some fields it is not mandatory to use the methods shown herein. They are suggestions and are used in the examples. Individuals or businesses wishing to use or develop their own proprietary methods should ensure that they meet the reasoning outlined in the relevant section. That is, they are not at cross-purposes with methods implemented by others with whom they are communicating.
The information included in this guide includes recommended actions, structures, content and values that are the preferred options. Using them increases the likelihood that conflicts can be avoided.
One aspect included in this guide and not covered by the HL7 protocol relates to the transfer of messages between the pathology providers and healthcare providers where the HL7 lower layer protocol is not appropriate (see HL7 Implementation Guide www.hl7.org.au/downloads). In many cases this will occur between private surgeries and private pathology laboratories. Relevant issues relating to file processing, and data encryption are discussed in some sections. Where this is not applicable to a real-time installation these sections can be ignored.
The processes of signing, encryption and transmission are not defined nor discussed in this guide.
