R4 Ballot #2 (Mixed Normative/Trial use)

This page is part of the FHIR Specification (v3.5.0: R4 Ballot #2). The current version which supercedes this version is 5.0.0. For a full list of available versions, see the Directory of published versions . Page versions: R4B R4 R3 R2

10.2 Resource Media - Content

Orders and Observations

Work Group

Maturity Level: 1

Trial Use

Compartments: Device, Patient, Practitioner

A photo, video, or audio recording acquired or used in healthcare. The actual content may be inline or provided by direct reference.

10.2.1 Scope and Usage

Trial-Use Note: The Orders and Observations workgroups wants to make the balloter aware than observations that require the attachment data types are represented by the Media resource instead of Observation. There have been several significant changes to the Media resource in order to align it with Observation and the workflow event pattern including:

The addition of the partOf and issued elements.

The required type was changed an optional category and the subtype element was renamed to modality.

Additional reference targets added to the subject,operator, and basedOn elements

The additions of several standard event extensions.

The Media resource contains photos, videos, and audio recordings. It is used with media acquired or used as part of the healthcare process. Here are some typical usages:

Photos and videos of diagnostic or care provision procedures for recording purposes
Images contained in diagnostic reports

10.2.2 Boundaries and Relationships

This resource captures a specific type of Observation - an Observation whose value is audio, video or image data. This resource is the preferred representation of such forms of information as it exposes the metadata relevant for interpreting the information. However, in some legacy environments, media information may occasionally appear in Observation instead. Systems should be aware of this possibility.

The Media resource is able to contain medical images in a DICOM format. These images may also be made accessible through an ImagingStudy resource, which provides a direct reference to the image to a WADO-RS server.

For such images, the WADO-RS framework is a preferred method for representing the images - the WADO-RS service may include rendering the image with annotations and display parameters from an associated DICOM presentation state, for instance.

On the other hand, the media resource allows for a robust transfer of an image across boundaries where the WADO-RS service is not available. For this reason, medical images can also be represented in a Media resource, but the Media.content.url should provide a reference to a source WADO-RS service for the image.

This resource is referenced by AdverseEvent, ClinicalImpression, DeviceUseStatement, DiagnosticReport, ImagingStudy, MedicationKnowledge and Observation

10.2.3.2 Implementation Notes

The media resource contains several date/times:

Media.created[x] - The date(/time) of collection, or the period over which collection occurred
Media.duration - The duration of the media. The duration might differ from createdPeriod if recording was paused
Media.content.creation - This should be consistent with the Media.created[x] but might be different due to partial / edited recordings

This resource can embed the image information directly through the attachment.data element. However, good practice is generally to use the attachment.url element to point to a Binary resource. Servers will frequently be able to persist Binary resources in purpose-dedicated repositories more suitable to potentially large artifacts.
