R6 Ballot (1st Draft)

14.10 Resource EventDefinition - Content

Clinical Decision Support icon Work GroupMaturity Level: 0 Trial UseSecurity Category: Anonymous Compartments: No defined compartments

The EventDefinition resource provides a reusable description of when a particular event can occur.

14.10.1 Scope and Usage

This resource is a definition resource from a FHIR workflow perspective - see Workflow, specifically Definition.

The EventDefinition provides a reusable description of an event. The resource supports describing different kinds of events, including named events, periodic events, and data-based events. For each of these, the resource also supports a formal description of the event. For example, a 'monitor-emergency-admissions' event can be a named event, but also provide a formal description of the event as monitoring for encounters that occur in emergency department locations.

Implementation Note: The EventDefinition resource is a candidate for removal from the specification. The resource was proposed prior to the development of the current subscriptions approach and the functionality it supports has been replaced by the SubscriptionTopic resource. We are seeking feedback on whether there would be any gaps left open by removing the EventDefinition in favor of making use of the SubscriptionTopic resource.

14.10.2 Boundaries and Relationships

The EventDefinition resource is intended to be used to provide a reusable description of events for use by other resources that require event definition, such as Subscription. EventDefinition is a definition of an event that could occur, whereas Subscription is asking for notification of events when they occur.

14.10.4.1 Terminology Bindings

PathValueSetTypeDocumentation
EventDefinition.versionAlgorithm[x] VersionAlgorithm Extensible

Indicates the mechanism used to compare versions to determine which is more current.
EventDefinition.status PublicationStatus Required

The lifecycle status of an artifact.
EventDefinition.subject[x] ParticipantResourceTypes Extensible

All Resource Types that represent participant resources
EventDefinition.jurisdiction JurisdictionValueSet Extensible

This value set defines a base set of codes for country, country subdivision and region for indicating where a resource is intended to be used.

Note: The codes for countries and country subdivisions are taken from ISO 3166 icon while the codes for "supra-national" regions are from UN Standard country or area codes for statistical use (M49) icon.
EventDefinition.topic DefinitionTopic Example

High-level categorization of the definition, used for searching, sorting, and filtering.
