Resource Profile: Observation Results - Radiology (IPS)

This profile represents the constraints applied to the Observation resource by the IPS project, which specifies a radiology observation for the international patient summary based on the FHIR standard R4.

This observation may represent the conclusions of a diagnostic procedure such a Chest RX, or it may group the set of results produced by that single or multi-modality procedure.

In the latter case, the main observation (this one) carries the overall conclusion of the study and/or a global interpretation by the observer of the study as value of this observation; and may reference the atomic results of the study as "child observations".

It allows also providing details about the related study using the partOf element referring to an ImagingStudy resource.

Usage:

• Use this Resource Profile: Bundle (IPS)
• Refer to this Resource Profile: Composition (IPS), DiagnosticReport (IPS) and Observation Results - Radiology (IPS)
