Mandatory and Must Support Data Elements

The following data-elements are mandatory (i.e., data MUST be present) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each must have:

1. A logical id
2. A type code of "message"
3. A timestamp
4. An entry for the MessageHeader
5. An entry for the event or request resource reference by 'MessageHeader.focus'

Additional Profile specific implementation guidance:

The elements Bundle.total, Bundle.entry.search, Bundle.entry.request, and Bundle.entry.response are Cardinality = 0..0 (in other words, constrained out) because of the invariants bdl-1.bdl-3.bdl-3. and bdl-4 defined in the FHIR Bundle resource.

Examples

For examples of this profile within a bundle, see these message Bundles examples:

• Admit Notification Intermediate Translate Bundle
• Admit Notification Intermediate Transmit Bundle
• Admit Notification Message Bundle 01
• Admit Notification Message Bundle 02
• Discharge Notification Message Bundle
• Transfer Notification Message Bundle
