+`order-discontinue`
+
+!!! info
+    This page defines a workflow [hook](../../specification/current/#hooks) for the purpose of providing clinical decision support using CDS Hooks. This is a build at the level of [Draft](http://hl7.org/fhir/versions.html#std-processs).
+
+| Metadata | Value
+| ---- | ----
+| specificationVersion | 1.0
+| hookVersion | 0.1.0
+| hookMaturity | [0 - Draft](../../specification/current/#hook-maturity-model)
+
+## Workflow
+
+The `order-discontinue` fires when a signed order is manually discontinued by a clinician (including orders for medications, procedures, labs and other orders). Note that this hook does not fire when an order expires "naturally", for example at a predictable time, such as a a medication prescription's refills completing.
+
+## Context
+CDS Services should consider retreiving or prefetch'ing the `toBeDiscontinued` order, and should focus decisions support on the discontinuation of this order.
+
+Field | Optionality | Prefetch Token | Type | Description
+----- | -------- | ---- | ---- | ----
+`userId` | REQUIRED | Yes | *string* | The id of the current user.<br />For this hook, the user is expected to be of type [Practitioner](https://www.hl7.org/fhir/practitioner.html) or [PractitionerRole](https://www.hl7.org/fhir/practitionerrole.html).<br />For example, `PractitionerRole/123` or `Practitioner/abc`.
+`patientId` | REQUIRED | Yes | *string* |  The FHIR `Patient.id` of the current patient in context
+`encounterId` | OPTIONAL | Yes | *string* |  The FHIR `Encounter.id` of the current encounter in context
+`toBeDiscontinued` | REQUIRED | No| *object* | FHIR Bundle with the orders resources bring discontinued.  <br/ > DSTU2 - FHIR Bundle of MedicationOrder, DiagnosticOrder, DeviceUseRequest, ReferralRequest, ProcedureRequest, NutritionOrder, VisionPrescription. <br/ > STU3 - FHIR Bundle of MedicationRequest, ReferralRequest, ProcedureRequest, NutritionOrder, VisionPrescription. <br/ > R4 - FHIR Bundle of DeviceRequest, MedicationRequest, NutritionOrder, ServiceRequest, VisionPrescription.
