EVS-EN ISO 21549-4:2014

This International Standard is applicable to situations in which such data is recorded on or transported by patient healthcare data cards compliant with the physical dimensions of ID-1 cards defined by ISO 7810. This International Standard specifies the basic structure of the data contained within the data object extended clinical data, but does not specify or mandate particular data-sets for storage on devices. In order to facilitate interoperability, whenever an application is built for use in the healthcare domain in compliance with this International standard, data items required for that application shall be drawn from the list of objects (some of which are extensible) as provided in clauses 6 to 8. These shall then be used in conjunction with other data defined in other parts of this International Standard. The detailed functions and mechanisms of the following services are not within the scope of thisInternational Standard, (although its structures can accommodate suitable data objects elsewhere specified): - the encoding of free text data - security functions and related services which are likely to be specified by users for data cards depending on their specific application, for example: confidentiality protection, data integrity protection, and authentication of persons and devices related to these functions; - access control services which may depend on active use of some data card classes such as microprocessor cards; - the initialisation and issuing process (which begins the operating lifetime of an individual data card, and by which the data card is prepared for the data to be subsequently communicated to it according to this Draft international standard). The following topics are therefore beyond the scope of this International Standard: - physical or logical solutions for the practical functioning of particular types of data cards; - how the message is processed further ‘downstream’ of the interface between two systems; - the form which data takes for use outside the data card, or the way in which such data is visibly represented on the data card or elsewhere.
