Generated Narrative: CodeSystem trigger-type

This case-sensitive code system http://hl7.org/fhir/trigger-type defines the following codes in an undefined hierarchy:

Lvl	Code	Display	Definition
1	named-event	Named Event	The trigger occurs in response to a specific named event, and no other information about the trigger is specified. Named events are completely pre-coordinated, and the formal semantics of the trigger are not provided.
1	periodic	Periodic	The trigger occurs at a specific time or periodically as described by a timing or schedule. A periodic event cannot have any data elements, but may have a name assigned as a shorthand for the event.
1	data-changed	Data Changed	The trigger occurs whenever data of a particular type is changed in any way, either added, modified, or removed.
2	data-added	Data Added	The trigger occurs whenever data of a particular type is added.
2	data-modified	Data Updated	The trigger occurs whenever data of a particular type is modified.
2	data-removed	Data Removed	The trigger occurs whenever data of a particular type is removed.
1	data-accessed	Data Accessed	The trigger occurs whenever data of a particular type is accessed.
1	data-access-ended	Data Access Ended	The trigger occurs whenever access to data of a particular type is completed.
1	subscription-topic	Subscription Topic	The trigger occurs as defined by a subscription topic.
