This is part four of the multi part standard EN 14822: Health informatics - General purpose information components with the following parts: Part 1: Overview Part 2: Non-Clinical Part 3: Clinical Part 4: Message headers According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. CEN/TS 14822-4:2005 Licensed CopyChinese University of Hong Kong, 20/10/2008 09:32, Uncontrolled Copy, (c) BSI 4 Introduction Many previous messaging 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 components 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 Specification 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 harmonisation 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 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 new 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 described 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 message header General Purpose Information Components. 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 about 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 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 to 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 Specification, 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. Longmans 1995 3.4 healthcare agent healthcare person, healthcare organisation, healthcare device or that performs a role in a healthcare activity 3.5 message communication in writing, speech or by signals 3.6 organisation unique framework of authority within which a person or persons act, or are designated to act towards some purpose NOTE Groupings or subdivisions of an organisation may also be considered as organisations where there is need to identify them for information interchange.

In particular, A conformant system that utilises a GPIC shall be able to receive and process information present in all classes and attributes, even where the attributes are specified as being optional. 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 GPIC (RelatedMessage) which in effect extends the functionality of the GPIC. This extension is informative in nature and shall not subject to conformance testing. 6 General Purpose Information Components CEN/TS 14822-4:2005 Licensed CopyChinese University of Hong Kong, 20/10/2008 09:32, Uncontrolled Copy, (c) BSI 7 6.1 Communicating Party 6.1.1 General Description GPIC Name CommunicatingParty GPIC_ID = 4.001 Description Information about the devices and the organisations that are using these devices in the sending and/or receiving of communications. Notes 1. Each communication shall have one device/organisation which is acting in the role of sender and at least one device/organisation which is acting as the recipient of the communication. 2. This GPIC is generally concerned with the transport of the message. Details of the persons that are acting as sender or recipient should be included in the content of the message. Examples Sending doctor, receiving laboratory UML Representation CommunicationFunction type_cd: CS (sender, receiver) External Interface GPIC Core 1 1* classCode: CS Identifier(s) for the organisation that is acting as a communication sender or receiver name O ST Name of the organisation telecom O Telecom One or more telecommunication numbers/addresses or the communicating organisation 6.2 Message Transmission 6.2.1 General Description GPIC Name MessageTransmission GPIC_ID = 4.002 Description The “envelope” into which a message is placed. Use This GPIC resides at the head of the message and therefore does not have a conventional GPIC interface requirement. However, the class ControlEvent is shown as the point at which the message content is to be attached. It is mandated that the ControlEvent class will interface to a class of general CEN/TS 14822-4:2005 Licensed CopyChinese University of Hong Kong, 20/10/2008 09:32, Uncontrolled Copy, (c) BSI 10 type ACT, i.e. the message content will always start with an ACT class or one of its specialisations. Notes The ControlAct class is not described here except to the extent that it is necessary that the instance of MessageTransmission will normally be associated with a message payload and where there is a payload, this shall always start with an Act class (ControlAct). Although the content of the ControlAct is not described here, the content should describe the act of message sending/receiving, i.e. provide information about the sender, receivers (as persons/organisations), the purpose of the message, date and time of its creation, etc. MessageTransmission is not associated directly with a payload (ControlAct) only where a message is merely being referred to as in the RelatedMessage GPIC.
