FHIR Document (Bundle)

The CH ELM exchange format is defined as a document type that corresponds to a Bundle as a FHIR resource. A Bundle has a list of entries. The first entry is the Composition, in which all contained entries are then referenced.

The exchange format defines the FHIR document for reporting to the FOPH so that one document per organism per patient is submitted.

Fig. 2: Laboratory Report

Each CH ELM document requires

• a Composition resource with the metadata for the document
• a DiagnosticReport resource indicating for which organism the report is

Here you will find an overview of the resources and their references to each other for which profiles are defined to represent the CH ELM laboratory report.
