The Digital Child Health Event Message Bundle Structure
To enable a standardised structure to carry information regarding event messages within the scope of the Digital Child Health Events specification, the Bundle and the Message Header resources combine to make up the initial event message bundle structure:
This is consistent with the FHIR specification for the Bundle resource, which states that ‘A message bundle (type = “message”) consists of a series of entries, the first of which is a MessageHeader.’
MessageHeader focus
The root class of the MessageHeader is fulfilled using the ‘focus’ element in the resource. For Digital Child Health events this will reference the Encounter resource.
