12.18.9 Resource PlanDefinition - Operations

Clinical Decision Support Work Group

Maturity Level: 2

Trial Use

Compartments: Not linked to any defined compartments

This resource has 2 operations associated with it:

For more information about operations, including how they are invoked, see Operations.

12.18.9.1 Apply

The apply operation applies a PlanDefinition to a given context

The official URL for this operation definition is

 http://hl7.org/fhir/OperationDefinition/PlanDefinition-apply

Formal Definition (as a OperationDefinition).

URL: [base]/PlanDefinition/[id]/$apply

This is not an idempotent operation

The result of this operation is a CarePlan resource, with activities for each of the applicable actions based on evaluating the applicability condition in context. For each applicable action, the activitydefinition is applied as described in the $apply operation of the ActivityDefinition resource, and the resulting resource is added as an activity to the CarePlan. If the ActivityDefinition includes library references, those libraries will be available to the evaluated expressions. If those libraries have parameters, those parameters will be bound by name to the parameters given to the operation

12.18.9.1.1 Examples

Apply the low suicide risk order set to patient 124 (Request):

GET [base]/PlanDefinition/example/$apply?patient=124

Returned on successful application of the order set (Response):

HTTP/1.1 200 OK

12.18.9.2 Data Requirements

The data-requirements operation aggregates and returns the parameters and data requirements for the plan definition and all its dependencies as a single module definition library

The official URL for this operation definition is

 http://hl7.org/fhir/OperationDefinition/PlanDefinition-data-requirements

Formal Definition (as a OperationDefinition).

URL: [base]/PlanDefinition/[id]/$data-requirements

This is not an idempotent operation

The effect of invoking this operation is to determine the aggregate set of data requirements and dependencies for the plan definition. The result is a Library resource with a type of module-definition that contains all the parameter definitions and data requirements of the plan definition and any libraries referenced by it. Implementations SHOULD aggregate data requirements intelligently (i.e. by collapsing overlapping data requirements)

12.18.9.2.1 Examples

Request data requirements for the Zika Virus intervention plan definition (Request):

GET [base]/PlanDefinition/zika-virus-intervention/$data-requirements

Returned on successful evaluation (Response):

HTTP/1.1 200 OK
