DIN EN ISO 13606-5:2010-09

This standard series specifies the information architecture required for interoperable communications between systems and services that need or provide EHR (electronic health record) data. This standard series does not specify the internal architecture or database design of such systems. The subject of the record or record extract to be communicated is an individual person, and the scope of the communication is predominantly with respect to that person's care. Uses of healthcare records for other purposes such as administration, management, research and epidemiology, which require aggregations of individual people's records, are not the focus of this standard, but such secondary uses could also find this document useful. Part 5 of this standard defines a set of interfaces to request and provide: an EHR EXTRACT for a given subject of care as specified in part 1 of this standard series; one or more ARCHETYPE(s) as specified in the part 2 of this standard series; an EHR AUDIT LOG EXTRACT for a given subject of care as specified in part 4 of this standard series. Part 5 specifies a set of interactions for requesting each of these artifacts, and for providing the requested data or declining requests. An interface to query an EHR or populations of EHRs, for example for clinical audit or research, is beyond its scope, although provision is made for certain selection criteria to be specified when requesting an EHR EXTRACT which might also serve for population queries. Part 5 defines the computational viewpoint for interfaces, without specifying or restricting particular engineering approaches to implement these as messages or as service interfaces. Part 5 effectively defines the payload to be communicated at each interface. It does not specify the particular information that different transport protocols will additionally require, nor the security or authentication procedures that might be agreed between the communicating parties or required by different jurisdictions.
