eHN Imaging Studies and Reports Guidelines

This model is (still) based on a logical model based on the eHN Imaging Studies and Reports. It will need to be updated to the XtEHR Imaging Logical Model
Update the model

Overview

The European eHealth Network "Guideline on the electronic exchange of health data under Cross-Border Directive 2011/24/EU Medical imaging studies and reports, release 1.1" is addressed to the Member States of the European Union and applies to the implementation of interoperable cross-border exchange of imaging study reports in order to support safe and efficient provisioning of care services in another member state.

It could also serve as a guiding principle for the national development and implementation of imaging study reports.

eHN Imaging Studies and Reports guidelines logical model

The eHN Imaging Studies and Reports guidelines in section 4 specifies a DATASET, which is a simplified logical model of a imaging study manifest and report. The data set comprises of several basic parts as visualized in the diagram below.

Figure: eHN Imaging Study and Report dataset

The following table lists the HL7 FHIR logical models used to represent this dataset. To facilitate the references with the eHN Imaging Studies and Reports guidelines data sets the short description of each element reports the label of the eHN element (e.g., A.1.7.2 Result validator name).

The HL7 FHIR logical model requires that element cardinality is specified, while the eHN Imaging Studies and Reports guidelines data set doesn't define them on purpose. For this reason the elements' cardinality of the following FHIR Logical Model should be interpreted with this in mind, thus they should not be considered as "normative".

TitleDescription
B Imaging study manifest data set (eHN)

The data set defines the contents of the key information about the imaging study as conveyed by the imaging study manifest data set. The imaging study manifest contains key information about the imaging study that is referenced, including the “pointers” that allow access to the series of images. It is important to note that the metadata used in expressing the filters associated with the querying for a list of imaging studies and/or imaging reports are defined in Section 2 Article 10: Selection List and filtering Parameters. These parameters are expressed as coded values from standardised value sets to ensure a robust search for a list of relevant imaging studies. Such metadata filtering parameters are associated with imaging studies, but may not be present in the content of the imaging study manifest.

Result validator

A.2 Order information

Note: an imaging report could respond to multiple orders.

A.5.3 Adverse reaction

A.5.5 Conclusion

A concise and clinically contextualised summary including interpretation/impression of the diagnostic report

A.5 Examination Report

Examination Report

A.5.1 Imaging procedure description

Note: this part records the technical details of the performed procedures and may include information about protocol, imaging phases, imaging device, anatomical location, performer, place, date and time of performance.

A.5.2 Medication

Medication section includes information about medication administered during the medical imaging examination (contrast, sedation, stress agents), etc.

A.5.6 Recommendation

Recommendation

A.5.4 Results

Note: The results summarise the findings and observations by the health professional following the imaging study. Note: this part includes textual as well as structured results or findings of the imaging investigation.

Key images associated with this report

A.8 Presented form

Presented form

A.3 Order Reason

Note: an imaging report could respond to multiple reasons.

A.4 Specimen information

Note: a specimen (not attached to a body) can be used for diagnostic, forensic and medical research purposes.

Logical model mapping onto HL7 FHIR

The following FHIR ConceptMaps describe the way the logical model has been mapped onto the FHIR profiles defined in this specification.

TitleDescription
A.1.1 Identification of the patient/subject mapping

This concept map defines the mapping between the A.1.1 Identification of the patient/subject section and the FHIR profiles.

A.1.2 Patient/subject related contact information mapping

This concept map defines the mapping between the A.1.2 Patient/subject related contact information section and the FHIR profiles.

A.1.3 Health Insurance and Payment Information mapping

This concept map defines the mapping between the A.1.3. Health Insurance and Payment Information section and the FHIR profiles.

A.1.4 Information Recipient

This concept map defines the mapping between the A.1.4 Information Recipient section and the FHIR profiles.

A.1.5 Information Author

This concept map defines the mapping between the A.1.5 Information Author section and the FHIR profiles.

A.1.6 Legal Authenticator

This concept map defines the mapping between the A.1.6 Legal Authenticator section and the FHIR profiles.

A.1.7 ResultValidator

This concept map defines the mapping between the A.1.7 Result Validator section and the FHIR profiles.

A.1.8 Document Metadata

This concept map defines the mapping between the A.1.8 Document Metadata section and the FHIR profiles.

A.2 Order Information to FHIR profiles

This concept map defines the mapping between the A.2 Order Information section and the FHIR profiles.

A.3 Order Reason to FHIR profiles

This concept map defines the mapping between the A.3 Order Reason section and the FHIR profiles.

A.4 Specimen

This concept map defines the mapping between the A.3 Order Reason section and the FHIR profiles.

The Specimen relates to a different type of information stored in a PACS: digital pathology. This has to analysed in more detail before inclusion in the IG. One of the things that might be impacted is the structure of the report.

A.5.1 Imaging Procedure Description

This concept map defines the mapping between the A.3 Order Reason section and the FHIR profiles. The rationale related to representing procedure phases can be found in Design consideration: Procedure Phases.

A.5.2 Imaging Procedure Medication

This concept map defines the mapping between the eHN A.5.2-ImagingProcedureMedication section and the FHIR profiles. The medication information is mapped on the FHIR Medication resource. The use of the medication is modelled using MedicationDispense. Links to these resource are added to the composition resource.

A.5.3 Adverse reaction

This concept map defines the mapping between the eHN A.5.3 Adverse reaction section and the FHIR profiles. In FHIR, adverse reactions are modelled using the AdverseEvent resource.

A.5.4 Results

This concept map defines the mapping between the eHN A.5.4 Results section and the FHIR profiles. In FHIR, these are mapped on Observation resources.

A.5.5 Conclusion

This concept map defines the mapping between the eHN A.5.5 Conclusion section and the FHIR profiles. The coded conclusions and narrative are mapped directly on DiagnosticReport, they are also present in Composition.section.text. In FHIR, these are mapped on Observation and Condition resources.

A.5.6 Recommendation

This concept map defines the mapping between the eHN A.5.6 Recommendation section and the FHIR profiles. The eHN Guideline requires narrative recommendations only. It also states that in the future it is expected to also contain structured and coded recommendations. In order to support a transition towards a structured and coded format, the mapping is defined to the FHIR CarePlan resource. This also prevents akward mappings on the text field of Composition.section.

A.6 Key images associated with this report

This concept map defines the mapping between the eHN A.6 Key images associated with this report section and the FHIR profiles.

A key choice in modelling this dataset is the resources to use, the model is based on the design consideration on key image representation, both the DocumentReference and ImagingSelection resources are used to represent the key images.

A.7 Comparison Study

This concept map defines the mapping between the eHN A.7 Comparison Study section and the FHIR profiles.

A.8 Comparison Study

This concept map defines the mapping between the eHN A.8 Comparison Study section and the FHIR profiles.

B Comparison Study

This concept map defines the mapping between the eHN B Comparison Study section and the FHIR profiles.
