This publication is not to be regarded as a British Standard. It is being issued in the Draf
3、t for Development series of publications and is of a provisional nature. It should be applied on this provisional basis, so that information and experience of its practical application can be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience ca
4、n be reported to the European organization responsible for its conversion to a European standard. A review of this publication will be initiated not later than three years after its publication by the European organization so that a decision can be taken on its status. Notification of the start of t
5、he review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the Technical
6、Specification or to withdraw it. Comments should be sent to the Secretary of the responsible BSI Technical Committee at British Standards House, 389 Chiswick High Road, London W4 4AL. The UK participation in its preparation was entrusted to Technical Committee IST/35, Health informatics. A list of o

19、g and information structure standards for health have overlapping parts with a number of objects being defined in separate documents, sometimes with small variations making implementation of conformant applications more difficult. It therefore makes sense to define a set of general purpose component
20、s that can be used for definition of message structures for different purposes. This approach was suggested and approved as a strategy for CEN/TC 251 in the Short Strategic Study on message standards alignment in 1999 examining a set of five European Standards for messages. This Technical Specificat
21、ion is aiming to provide such a set of components and has been developed jointly with a new European Standard for Service Request and Report messages that is using the components defined herein. Another important background to the development of this Technical Specification has been the wish for a h
22、armonisation of information models for health developed in Europe and the USA expressed in the collaboration agreement entered March 2000 between CEN/TC 251 and HL7 (Health Level Seven, Ann Arbor. Michigan). The goal was set for a maximum degree of alignment while maintaining their independence and
23、need to serve the business requirements of the respective markets but also to make the results available to ISO for possible international standardization. HL7 have adapted a general strategy similar to CEN/TC 251 using information modelling expressed in UML (Unified Modelling Language) for their ne
24、w standards and a lot of interaction and information sharing has occurred between CEN experts and HL7 in an open spirit of collaboration. This Technical Specification includes a large number of objects which are technically identical to descriptions in draft documents of HL7, although partly describ
25、ed differently due to the fact that CEN is following the ISO rules for drafting and presentation of standards which HL7 is not. CEN wishes to express its gratitude towards HL7 experts for generously sharing their models with the European expert team. This part 4 document is definition of a set of me

CEN/TS 14822-4:2005 Licensed CopyChinese University of Hong Kong, 20/10/2008 09:32, Uncontrolled Copy, (c) BSI 5 1 Scope It is now widely or even universally accepted that computer systems that are used within healthcare to record information abou
27、t the care given to patients need to share that information with other computer systems and their users. In order that computer systems may share information effectively there is a requirement that the communicating parties, and particularly their computer systems have a common understanding of how
28、the information which they are sharing is represented. This sharing of representation needs to take place at a number of levels, most notably at the data representation or syntactic level which is the subject of CEN/TS 14796, but also at the macro or semantic level where groupings of data are used t
29、o provide a context or set of contexts for the data. This part 4 of the standard is limited to descriptions of components concerned with messaging, and in particular the message and batch headers. 2 Normative References Not applicable. 3 Terms and Definitions For the purposes of this Technical Speci
30、fication, the following terms and definitions apply. 3.1 batch collection of messages 3.2 communicating party person, organisation or device which acts in the role of a sender or receiver of a communication 3.3 communication techniques for the effective transmission of information, ideas, etc. Longm

In particular, A conformant system that utilises a GPIC shall be able to receive and process information present i

A conformant system that utilises a GPIC to send information shall not be obliged to populate optional attributes. 5.2 One of the GPICs described (MessageTransmission) in this part may be associated with another
