Usage

The primary use of the DocumentReference in this IG is to exchange binary .content (attachments to ServiceRequests) in DirectMessaging integrations.

In the referral workflow multiple, large binary files could potentially be referenced as ServiceRequest.supportingInfo. To reduce message size, message performance and scalability, implementers are strongly recommended to use .content.attachment.url to enable asyncronous retrieval of binary attachments from a secure server instead of passing attachments within a message as base64 .content.attachment.data. For further background and discussion about potential approaches see: https://infocentral.infoway-inforoute.ca/en/resources/docs/3551-documentreference/view-document

Notes

.id

  • used to uniquely identify the resource
  • if a persistent identity for the resource is not available to use when constructing a message Bundle for transmission via Direct Messaging, a UUID SHOULD be used in this element (with a corresponding value in Bundle.entry.fullUrl)

.meta.profile

  • used to declare conformance to this profile
  • populate with a fixed value: http://ehealthontario.ca/fhir/StructureDefinition/ca-on-eReferral-profile-DocumentReference|1.0.0

.identifier

  • business identifier(s)

.status

  • populate with a fixed value "current"

.subject

  • MAY be used to associate the DocumentReference with the Patient it is about
  • where .subject is populated, it SHALL reference the same Patient resource as ServiceRequest.subject
  • for DirectMessaging integrations, the Patient resource SHALL be included in the message as a Bundle.entry and, if a persistent resource is available, MAY also be resolvable at a RESTful FHIR endpoint

.date

  • populate with the instant in time when the DocumentReference was created for transmission to the recipient
  • format: YYYY-MM-DDThh:mm:ss.sss+zz:zz (e.g. 2015-02-07T13:28:17.239+02:00 or 2017-01-01T00:00:00Z).
