Workflow

The order-sign hook fires when a clinician is ready to sign one or more orders for a patient, (including orders for medications, procedures, labs and other orders). This hook is among the last workflow events before an order is promoted out of a draft status. The context contains all order details, such as dose, quantity, route, etc, although the order has not yet been signed and therefore still exists in a draft status. Use this hook when your service requires all order details.

This hook can also be used when an order or set of orders is being 're-signed' after revision (e.g. change to status, extending dates, or other changes allowed to signed orders within the system's workflow). In this case, the orders would typically have a status other than 'draft'. In some cases, the hook might fire with a mixture of new and revised orders.

This hook is intended to replace (deprecate) the medication-prescribe and order-review hooks.

A Note Concerning FHIR Versions

CDS Hooks is designed to be agnostic of FHIR version. For example, all versions of FHIR can represent in-progress orders but over time, the specific resource name and some of the important elements have changed. Below are some of the mosty commonly used FHIR resources for representing an order in CDS Hooks. This list is intentionally not comprehensive.

  • DSTU2 - FHIR Bundle of MedicationOrder, ProcedureRequest
  • STU3 - FHIR Bundle of MedicationRequest, ProcedureRequest
  • R4 - FHIR Bundle of MedicationRequest, ServiceRequest
