HB 262-2012

This Handbook provides support for AS4700.2-2007, which is the Standard for implementing external messaging using HL7 between diagnostics providers and all health service providers in Australia, using HL7Version 2.4.

This Handbook provides sufficient detail and discussion for the implementation of an HL7 based system for diagnostics messaging. It is intended that it be used as an implementation guide in conjunction with AS 4700.2 and HL7 V2.4.Diagnostics messaging implementation comprises both orders and results.The guidelines are presented in three stages:Overview of HL7 structure and operation.Discussions on issues relating to diagnostics messaging in Australia.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. However, this Handbook describes methodologies and field structures and ways in which the content can be developed.One aspect which is included and not covered by the HL7 protocol relates to the transfer of messages between diagnostics 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 clinics and private diagnostic facilities. 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.
