Mapping of Core Information Model Classes

Bitte markieren Sie Kommentare zu diesem Abschnitt mit dem Code {MdaBs.01}

This section defines the XDS-Metadata bindings for the classes of the EFA core information model.

The following table describes how EFA classes MUST be mapped to classes and object types of IHE ITI.

EFA core information model IHE ITI
Patient Patient
eCR CaseRecord Set of Folder-objects, that have values of Folder.patientID and Folder.codeList in common
eCR Partition Folder
eCR Medical Data Object DocumentEntry for metadata, Document for binary data

The object type SubmissionSet of IHE ITI has no corresponding class of the EFA core information model. Therefore, SubmissionSet SHALL be used as specified in IHE ITI but it MUST NOT have EFA semantics.

Mapping of PIM Classes

Bitte markieren Sie Kommentare zu diesem Abschnitt mit dem Code {MdaBs.01}

This section defines the XDS-Metadata bindings for the classes of the EFA platform independent model.

Instances of ECR PIM Classes are shared through XD* transactions and within XD* metadata. The following table shows the respective binding of these classes to IHE XD* message arguments and ebRS metadata slots/elements.

EFA PIM IHE ITI Metadata Model Comments
patientID Folder.patientId

DocumentEntry.patientId

-
communityID DocumentEntry.homeCommunityId

Folder.homeCommunityId

-
purpose Folder.codeList see XDS Folder Metadata
consentInfo Document ECR consentInfo objects are represented as structured, coded documents. See "Leitfaden Patienteneinwilligung" for details. The binding of consentInfo is not subject to the EFA Specification. An EFA domain must agree on a specific binding. Implementation Guide for CDA®, Release 2: Consent Directives, Release 1 MAY be used.
consentDoc Document Consent documents are represented as documents of a format that is to be agreed by each ECR domain (e.g. PDF/A).
partitionID Folder.uniqueId see IHE ITI TF Vol3 section 4.1.9.1 for details
partitionList set of Folder objects -
ecrRef Folder.patientId

Folder.codeList

Folder.homeCommunityId

Folders that have the same patient ID and the same purpose codes form a distinct case record. The homeCommunityId indicates the XDS Affinity Domain where the reference is valid.
partitionInfo Folder see XDS Folder Metadata for details
docMetadata DocumentEntry see XDS Document Metadata for details
docRelationship Document Relationship see Append and Replace in IHE ITI TF-3#4.1.2
documentID DocumentEntry.uniqueId

DocumentEntry.repositoryUniqueId

shall be used for document retrieval (retrieveDocument transaction).
DocumentEntry.entryUUID shall be used for document referral (associations between registry entries)

MountPoint

Instances of the EFA PIM class MountPoint SHALL be bound to DocumentEntry as follows:

ECR PIM MountPoint attribute IHE XDS Metadata Attribute Comments
patientID DocumentEntry.patientId
sourcePatientID DocumentEntry.sourcePatientId
communityID DocumentEntry.homeCommunityId

The DocumentEntry SHALL be a member of a Folder. This Folder SHALL have a codeList classification containing

  • (code="ECR-mountpoint", codeSystem="IHE-D-Cookbook-FolderClassCode") and
  • a purpose code.

ecrStatus

The EFA PIM class ecrStatus MUST be implemented by means of access policies. The values of ecrStatus MUST correspond to access policies and system configuration as follows:

Open
The access policy implements the patient's consent.
Suspended
The access policy implements the patient's consent with the exception that only the consented case record manager and their substitutes are authorized.
Retired
No access policy permits access to the case record.
Archived
No XDS metadata and no documents reside in the EFA system.
