16、700.3:2002 2PREFACEThis Standard was prepared by the Joint Standards Australia/Standards New ZealandCommittee IT-014, Health Informatics, in response to requests from the health informaticscommunity. It covers implementation of the Health Level Seven (HL7) Version 2.3.1protocol, for communication in
17、 Australia and New Zealand between prescribers, dispensersand their healthcare trading partners.This Standard is a revision of AS/NZS 4700.3:1999, based on changes between HL7Version 2.3 and HL7 Version 2.3.1. The 1999 edition will remain available for 12 monthsafter the publication of this revision
18、.The previous edition of this Standard was based on an object-oriented data model thatidentified the players that needed to communicate with each other in a preferred electronicfuture. Since then, the Standard has been implemented and its value confirmed.Information transferred between the objects a
19、re known as interchanges, for theconvenience of system users, and these are grouped together into functional messages, forthe benefit of systems developers. The main groups of data required for each functionalmessage were identified before consideration of message syntax.HL7 is a healthcare applicat
20、ion protocol accredited as a Standard by the American NationalStandards Institute (ANSI). Level Seven refers to the highest level of the InternationalOrganization for Standardization (ISO) communications model for Open SystemsInterconnection (OSI)the application level. Issues within the application
21、level includedefinition of the data to be exchanged, the timing of the exchange and communication ofcertain errors to the application. This level supports such functions as security checks,identification of the participants, availability checks, negotiating exchange mechanismsand, importantly, struc
22、turing the data exchanges themselves.HL7 focuses on the interface requirements of the entire healthcare organization. It allowsdevelopment along the fastest possible track to the unique requirements of already installedhospital and departmental systems, some of which use mature technologies.Australi
23、a and New Zealand already have an existing base of healthcare institutions that usethe HL7 protocol to exchange key sets of data between different computer applicationsystems. While HL7 is concerned with addressing immediate needs, there is a very strongfocus on convergence with other Standards deve
24、lopment activities in the United States ofAmerica and international HL7 initiatives in countries such as Canada, Finland, Germany,India, Japan, the Netherlands, South Africa and the United Kingdom.The HL7 protocol is a collection of standard formats that specify the implementation ofinterfaces betwe
25、en computer applications. It is not rigid. Flexibility is built into theprotocol to allow compatibility for specialized data sets that have facility-specific needs.One of HL7s strengths is its inbuilt flexibility. However, that flexibility is also one of itsweaknesses. It is open to misinterpretatio
26、n in its structure and format. HL7 is based on thehealth environment in the USA. Implementation of the HL7 Version 2.3.1 Standard in theAustralian and New Zealand health environments requires a common and consistentapproach.A number of meetings were convened involving representatives from a wide ran
27、ge oforganizations in the health sector and from others interested in the health sector. Theorganizations represented in pharmacy came from State Pharmacy Boards, thePharmaceutical Society of Australia, Pharmacy Guild, Society of Hospital Pharmacists,various levels of the pharmaceutical industry, co
28、mmunity and Defence pharmacy. Themedical profession was represented by clinicians and administrators, and other healthAccessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on 05 Sep 2005AS/NZS 4700.3:20023professionals were represented at various times. The software industry, businessconsult
29、ancies, academia, the engineering profession and the Consumer Health Forum alsoparticipated. A very thorough object model was developed to identify all potentialinformation interchanges between participants, not only directly in the passing ofprescriptions, but also in the seeking and providing drug
30、 information, reporting adversedrug reactions, and seeking authorization and notifying dispensing of specific drugs.The purpose of this model was to determine how well HL7 would address Australian andNew Zealand needs, which were deliberately ambitious, and then to determine how eachidentified requi
31、rement would be satisfied by HL7.An arbitrary border was placed around the area of interest, since it is conceivable that everypiece of knowledge is in some way related to a medical prescription! It was decided that themanufacturer of drugs lay on the border, and that advising the manufacturer of an
32、 adversedrug reaction lay inside the area of interest, but that ordering supplies from a manufacturerlay outside. The purpose of this limitation was to limit the interchanges consideredit inno way limits HL7 usage per se.In this document, frequent reference is made to AS 4700.12001, Implementation o
33、fHealth Level Seven (HL7) Version 2.3.1 Part 1: Patient administration which covers theimplementation of HL7 Version 2.3.1 for patient administration within and betweenAustralian healthcare settings. AS 4700.1 provides an important foundation for the buildingof most clinical healthcare messages.The
34、IT-014-06-04, Prescription Messages working group has reviewed and interpreted datasegments and data elements that are mandatory (required), conditional (required, based on acondition) or optional, and relevant usage notes in the Australian and New Zealand healthenvironments.In preparation of this S
35、tandard, cognizance was taken of the work being done by otherparties with regard to patient confidentiality and adverse drug reactions.Accessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on 05 Sep 2005AS/NZS 4700.3:2002 4CONTENTSPage1 SCOPE 52 APPLICATION. 53 REFERENCED AND RELATED DOCUMEN

38、tions with suppliers.This Standard provides consistent use of data definitions as well as commentary andreferences to the International Organization for Standardization (ISO) and the NationalHealth Data Dictionary.For the purposes of this Standard, only human patients are considered.2 APPLICATION2.1
39、 GeneralThis Standard is a guide for use by health authorities, healthcare providers, healthcareinstitutions, health information technology vendors, health information technologyconsultants, the health informatics community and the general public.Australia and New Zealand already have an existing ba
40、se of healthcare institutions that usethe HL7 protocol to exchange key sets of data between different computer applicationsystems. However, because of HL7s inbuilt flexibility, it is open to misinterpretation instructure and format. Implementation of the HL7 Standard in the Australian and NewZealand
41、 health environments requires a common and consistent approach.This is not a stand-alone document. A good understanding and, preferably, workingknowledge of HL7 is essential, as this Standard is based on and frequently refers to the HL7Version 2.3.1 Protocol.2.2 Alert Variance to HL7 2.3.1 Field Len
42、gthsThe Better Medication Management System (BMMS) specifies either the exact or maximumlengths that are acceptable to BMMS applications. In some instances these exceed HL72.3.1 length but are within the specified field lengths as defined in Version 2.4. Theseoccurrences are notated in the specifica
43、tions. For all other instances developers need toensure that no more than the BMMS maximum lengths are sent as truncation will occur.Accessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on 05 Sep 2005AS/NZS 4700.3:2002COPYRIGHT6The following have been highlighted as being outside the HL7 2.
