Return to Sep 2018 Proposals

Order Catalog

Submitting WG/Project/Implementer Group

  • Orders and Observations


Resources and Resource profiles needed to support catalogs of various types (lab compendia, medication formularies, healthcare service directories, etc) are in an early draft stage. These include a Catalog profile on Composition, a CatalogEntry resource, an ObservationDefinition resource, a SpecimenDefinition resource, and potentially a profile on ActivityDefinition. This connectathon track is intended to test the design approach and confirm the resource set meets the needs of the use case. The track is based on the September R4 ballot

This will inform the development of the catalog resources, with a goal of reaching FMM 1 for FHIR Release.

FHIR version used

For this connectathon the catalog track will be based on the current build of FHIR. The reason for that is that a number of resources used by Catalogs (CatalogEntry, ObservationDefinition, SpecimenDefinition) have evolved after the publication of the September ballot. And these late evolutions are needed for this testing session.

Expected participants

The following organizations have indicated an interest in participating in this track:

  • Phast (France) - a FHIR server supporting a clinical lab compendium.
  • University of Utah will participate with a FHIR client able to query a lab compendium.
  • Quest Diagnostics (US laboratory) acting as a client administrating a lab compendium
  • Medlinx/Helix (Russian laboratory) acting as a client administrating and querying a lab compendium


Please include information here regarding how much advance preparation will be required if creating a client and/or server.

Catalog Server

A FHIR Server should support the following resources for this track:

  • Catalog Profile of Composition
  • CatalogEntry
  • Content resources appropriate to the type of catalog. For Lab:
    • ActivityDefinition
    • SpecimenDefinition
    • ObservationDefinition

A FHIR server is available for testing with sample data

Catalog Consumer

  • University of Utah: Client browsing the content of a clinical laboratory compendium
  • Quest Diagnostics: Client administrating a clinical laboratory compendium


This connectathon track will test the following interactions based on a clinical laboratory compendium:

Administration of the catalog by a clinical laboratory

  • Creation of new catalog entries
  • Update of catalog entries
  • Retirement of a catalog entry and replacement by another one

All these interactions use Bundle of type "transaction" and "transaction-response"

Query and retrieval of catalog entries by a CPOE system

Search Catalog by title

GET [base]/composition?title=[Catalog.title]


Check Catalog by id

GET [base]/composition/[catalogId]


Search catalog entry by name of specialty

Example: search for virology orderable tests and panels

Search catalog entry by name of orderable service

Example: search all entries corresponding to orderable tests or panels containing the word "sodium"

Retrieve details for an orderable diagnostic service

GET [base]/CatalogEntry?_has:Composition:_id=2&_id=[CatalogEntry id]
