Usage scenarios

The following are supported usage scenarios for this profile:

• Query for diagnostic imaging results for a patient
• Query for category of diagnostic imaging results (e.g. all x-ray)
• Record or update diagnostic imaging results belonging to a patient

Profile specific implementation guidance

• Observation.category provides an efficient way of supporting system interactions, e.g. restricting searches. Implementers need to understand that data categorisation is somewhat subjective. The categorisation applied by the source may not align with a receiver’s expectations.
• The observations MAY have additional codes that translate or map to the Observation code or category codes. For example:
  • providing a local code
  • providing a more specific code
• The Observation resource can represent a result using one or both of a single value with Observation.value, or set of results using either Observation.component.value or Observation.hasMember.
  • Although all are marked as must support, sending systems are not required to support all choices, but they SHALL support at least one of these elements
  • A receiving or persisting system SHALL support both elements
• Observation.identifier may contain the same identifier as in the order or report connecting the resources that are related to a single request fulfilment workflow

• Differential Table
• Key Elements Table
• Snapshot Table
• Statistics/References
• All
