Foundation

This Implementation Guide uses FHIR defined resources. For details on HL7 FHIR R4 see http://hl7.org/fhir/r4.

Because the Implementation Guide relies heavily on the FHIR Resources Questionnaire and QuestionnaireResponse, forms are addressed here as Questionnaires.

This Implementation Guide is derived from the Order & Referral by Form (ORF) Implementation Guide CH ORF which relies on HL7 Structured Data Capture Implementation Guide, see SDC IG and uses the Swiss Core Profiles, see CH Core.

Applications claiming for conformance with the CH RAD-Order Implementation Guide shall:

  • Render (and in case of the Questionnaire filler allow for data entry) all elements of a questionnaire in the user interface (e.g. on screen, in print).
  • For Clinical Information: Grouping of items and the order of items within shall be adequately reproduced according to the Questionnaire.

Actors, transcations and security considerations are covered in the corresponding sections of CH ORF.

Terminology

CH RAD-Order allows coding of the requested imaging service by means of LOINC/RSNA RADIOL0GY PLAYBOOK.

Systems such as PIS and KIS may not yet support RADIOLGY PLAYBOOK. For this reason, CH RAD-Order allows coding of the relevant dimensions by means of RADLEX.

The relevant dimensions are defined by PLAYBOOK such as:

  • Modality
  • Region
  • Focus
  • Laterlity
  • Maneuvre
  • Guidance for action (used for interventions)

Coding of these dimensions is done by RADLEX terms.

Value sets and coding are preliminary and not yet approved by eHealth Suisse.
