Resource Media - Content6.2

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

The resource name as it appears in a RESTful URL is [root]/media/

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 of patients and staff for identification purposes
  • Photos and videos of diagnostic or care provision procedures for recording purposes
  • Storing scans and faxes of paper documents where not enough metadata exists to create a DocumentReference
  • Images on diagnostic reports

Although the Media resource is allowed to contain images collected by a DICOM based system, DICOM images would preferentially be made available in a FHIR ecosystem by provision of an ImagingStudy resource with references to a WADO-RS server.
