12.18 12.21 Resource ActivityDefinition - Content

Responsible Owner: Clinical Decision Support icon Work Group   Normative Maturity Level : 2   Trial Use Security Category : Anonymous Compartments : Not linked to any No defined compartments

This resource allows for the definition of some activity to be performed, independent of a particular patient, practitioner, or other performance context.

12.18.1 12.21.1 Scope and Usage

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

An ActivityDefinition is a shareable, consumable description of some activity to be performed. It may be used to specify actions to be taken as part of a workflow, order set, or protocol, or it may be used independently as part of a catalog of activities such as orderables.

For more information on how activity definitions can be used to construct request resources, see the Realizing Applying an ActivityDefinition topic below.

12.18.2 12.21.2 Boundaries and Relationships

In general, an activity definition is simply a conceptual description of some specific action that should be taken. An instance of an ActivityDefinition does not indicate that any action has been performed (as an event resource does), nor does it indicate the actual intent to carry out any particular action (as a request resource does). Instead, an activity definition provides a reusable template that can be used to construct specific request resources such as ProcedureRequest ServiceRequest and MedicationRequest . This is different than a DataElement in that ActivityDefinitions are generally broader than data elements, which are typically used to describe more granular elements, such as a blood pressure, or the answer to a particular question.

Note that this is conceptually similar to the Task resource as well, with the distinction being that ActivityDefinition represents the description of a task in the abstract, while the Task resource is used to track a specific instance of a task as it moves through the steps of a workflow.

This is an arbitrary value managed by the activity definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0).

This SHALL be a URL, SHOULD be globally unique, unique and SHOULD be an a literal address at which an authoritative instance of this activity definition is (or will be) published. The This URL SHOULD include can be the major version target of a canonical reference. It SHALL remain the same when the activity definition.

This is an arbitrary value managed by the activity definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0).

This is the path on the resource that will hold the result of the calculation defined by the expression path : string [0..1] expression. The media specified path SHALL be a FHIRPath resolvable on the specified target type of the language for ActivityDefinition, and SHALL consist only of identifiers, constant indexers, and a restricted subset of functions. The path is allowed to contain qualifiers (.) to traverse sub-elements, as well as indexers ([x]) to traverse multiple-cardinality sub-elements (see the expression [Simple FHIRPath Profile](fhirpath.html#simple) for full details) language path : string [0..1] [1..1] An expression specifying the value of the customized element expression : string Expression [0..1] [1..1] Indicates who should participate in performing the action described participant [0..*] Dynamic values that will be evaluated to produce values for elements of the resulting resource. For example, if the dosage of a medication must be computed based on the patient's weight, a dynamic value would be used to specify an expression that calculated the weight, and the path on the intent request resource that would contain the result dynamicValue [0..*]

12.21.4.3 Applying an ActivityDefinition

An ActivityDefinition resource provides a description, or template, of an action to performed. These actions can be purely text-based descriptions of the action to be performed, only interpretable by a human user, or they can be structured definitions with enough information to construct a resource to represent the request or activity directly. This process of converting the ActivityDefinition into a specific request resource in a particular context is performed with the $apply operation.

In the simplest case, the process maps the elements specified in the ActivityDefinition to the corresponding elements on the request a resource of the appropriate type, using the kind element of the definition to determine the type of resource to be created.

More dynamic scenarios can be achieved in one of two ways, either by providing dynamicValue expressions, or by specifying a StructureMap that transforms the definition into the appropriate request resource.

Note that systems will likely vary widely in the degree of support they provide for the $apply operation. In particular, the fact that a system supports applying definitions of one category, does not imply that it supports applying definitions for all categories. For example, a service focused on medication order sets may have sophisticated support for MedicationRequest activities, but no support at all for the ProcedureRequest ServiceRequest activities.

The following diagram illustrates the relationship between the PlanDefinition and ActivityDefinition resources, as well as a typical realization application to CarePlan, RequestGroup, RequestOrchestration, and Request resources:

relationship-between-action-and-activity-definition

To accommodate the variability in systems and use cases, this specification is not prescriptive about exactly how an ActivityDefinition is applied to produce target request resources. However, the approach depicted above provides a general framework for the process, and the following steps provide more detail on the potential approach:

  1. Create the target resource of the type specified by the kind element and focused on the Patient in context
  2. Set the status of the target resource to draft
  3. Set the intent of the target resource to Note option
  4. Apply the structural elements of the ActivityDefinition to implementers: There the target resource such as code , timing , doNotPerform , product , quantity , dosage , and so on
  5. Resolve the participant element based on the user in context
  6. Resolve the location element based on the location in context
  7. If the transform element is some overlap between specified, apply the content transform to the resource. Note that can be specified the referenced StructureMap may actually construct the resource, rather than taking an instance. See the StructureMap for more information
  8. Apply any dynamicValue elements (in the order in which they appear in PlanDefinition.actionDefinition and the ActivityDefinition resource. Part resource) by evaluating the expression and setting the value of the work for FHIR Release 4 will be appropriate element of the target resource (as specified by the dynamicValue.path element)

Note that the parameters to resolve the overlap $apply operation are available within dynamicValue CQL and this will likely FHIRPath expressions as context variables, accessible by the name of the parameter prefixed with a percent (%) symbol. For example, to access the subject given to the apply, use the expression %subject .

In addition, the subject element establishes the context for CQL expressions evaluated during the operation, as discussed in the Evaluation Context discussion in the Using Expressions topic.

Note that result of this operation is transient (i.e. none of the resources created by the operation are persisted in some minor changes the server, they are all returned as contained resources in the result). The result effectively represents a proposed set of activities, and it is up to the structures. caller to determine whether and how those activities are actually carried out.

12.21.4.4 Event Resources

The kind element may only specify Request resource types to facilitate considering user input as part of processing the result of any automated clinical reasoning processes. To support creation of event resources, such as Observations, RiskAssessments, and DetectedIssues, use a Task resource with the focus of the task set to the event resource to be created.

12.18.3.3 12.21.4.5 Profiling ActivityDefinition

Because the ActivityDefinition resource can be used to describe many different types of request resources, profiles of the resource will be useful in communicating additional constraints and expectations about how the resource should be used in a particular context. For example, a profile of ActivityDefinition may specify that it is intended to describe medication orders within an order set. Such a profile would indicate that the quantity element should not be used, but the dosage element must be.

The following sections provide FHIR Mapping Language snippets for mapping ActivityDefinition instances to each kind of Request resource that can be created.
