CH ELM (R4), published by Federal Office of Public Health FOPH. This guide is not an authorized publication; it is the continuous build for version 1.7.0-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/ahdis/ch-elm/ and changes regularly. See the Directory of published versions
The CH ELM exchange format defines a FHIR document representing a coherent set of information specific to the transmission of laboratory data. This FHIR document is based on the CH Lab report document which is part of the CH LAB-Report Project.
The exchange format expects a separate FHIR document per patient, organism and test performed.
The FHIR document consists of a bundle-resource of type "document" (the terms "FHIR document" and "Bundle" are synonymous in the context of the CH ELM project).
The bundle resource contains a consistent set of entries representing FHIR resources specific for the transmission of laboratory data:
| { | ||||||
| "resourceType": "Bundle", | ||||||
| "entry": [ | ||||||
| { "resourceType": "Composition" }, |
parameters like date, language, title, author, and referring to the different resources | |||||
| { "resourceType": "DiagnosticReport" }, |
represents the laboratory report as a result of a lab order, with references to all other resources | |||||
| { "resourceType": "Patient" }, |
the person from whom the specimen was taken | |||||
| { "resourceType": "Observation" }, |
defines the analyzed organism with the laboratory test result-values, interpretation, and test execution date | |||||
| { "resourceType": "Specimen" }, |
the specimen material with collection date | |||||
| { "resourceType": "ServiceRequest" }, |
the lab order with the laboratory order ID, the requester, and performer of the laboratory test | |||||
| { "resourceType": "PractitionerRole" }, |
the orderer of the laboratory test containing a practitioner and/or organization | |||||
| { "resourceType": "Practitioner" }, |
the person ordering the laboratory test | |||||
| { "resourceType": "Organization" }, |
the organization ordering the laboratory test | |||||
| { "resourceType": "Organization" } |
the performing laboratory | |||||
| ] | ||||||
| } | ||||||
The FHIR document is generic and applicable for all types of organisms and reporting scenarios (use cases). For each resource within the FHIR document, a resource profile is defined to meet specific data needs depending on the context and use case.
Resource profiles are a way to customize and constrain FHIR resources to meet specific requirements depending on a particular context. These rules might restrict the allowable values for certain elements, specify additional mandatory elements, or define extensions to capture additional data beyond the standard FHIR resources. In the CH ELM Implementation Guide multiple profiles can exist based on the same FHIR resource.
Example: the FHIR resource «organization» is used to map the sender of the FHIR Document, the performing laboratory and the orderer of the laboratory test – each of which having its own profile.
The diagram “Resource Overview” illustrates the connections between the individual resource-profiles of a FHIR document.
See the examples in chapter 2.2 to learn how to use the resource profiles for different use cases and data requirements.
