This code system http://hl7.org/fhir/trigger-type defines the following codes:

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.
