Purpose
This guide provides an overview of the available standards and a recommended approach to support the Foreign Exam Management requirements as identified below. The intent is to simplify standards selection decisions in future projects and, in turn, to promote standardization of solutions across projects by providing useful information to support decision making in a readily consumable format.
Content in this guide was summarized from the Canadian XDS Affinity Domain Implementation Guide v1.1 20140527 to provide an accessible overview of the standards selected to support the listed Use Cases.
Business Context
Covered Use Cases
Recommended Approach
The following standards and related specifications were identified as candidates to support the in-scope requirements. Recommended standards are identified with summary of the rationale.
Areas of Standardization
Standardization Requirement | Options | Choice | Rationale |
Document and Image Sharing | IHE Cross-Enterprise Document Sharing - Imaging (XDS/XDS-I) | X | The IHE XDS-I.b profile specifies the use of existing standards including HL7 and DICOM to enable registration and sharing of images and reports. A Canadian XDS Affinity domain guide is available to support implementation of the profile. |
DICOM / HL7 |

Report Format | Clinical Document Architecture (CDA) R2 | X | It is the goal of the Canadian XDS Affinity domain that reports will be stored in HL7 CDA format (using the pan-Canadian header format) as these reports (a) support required metadata, and (b) can be transformed to all other formats.
* Raw text based HL7 ORU and DICOM SR are widely used and present in DI-R systems. |

Anatomic Region Code | Coarse Body Parts (SNOMED CT subset) | X | The DICOM CID 4 value set is very detailed and generally inconsistent with the general approach of “casting a wide net” employed when fetching content within the FEM use cases. |
