Workflow

The order-select hook occurs after the clinician selects the order and before signing.

This hook occurs when a clinician initially selects one or more new orders from a list of potential orders for a specific patient (including orders for medications, procedures, labs and other orders). The newly selected order defines that medication, procedure, lab, etc, but may or may not define the additional details necessary to finalize the order.

order-select is among the first workflow events for an order entering a draft status. The context of this hook may include defaulted order details upon the clinician selecting the order from the order catalogue of the CPOE, or upon her manual selection of order details (e.g. dose, quantity, route, etc). CDS services should expect some of the order information to not yet be specified. Additionally, the context may include previously selected orders that are not yet signed from the same ordering session.

This hook is intended to replace (deprecate) the medication-prescribe hook.

Ordering Flow Diagram

Context

Decision support should focus on the 'selected' orders - those that are newly selected or currently being authored. The non-selected orders are included in the context to provide context and to allow decision support to take into account other pending actions that might not yet be stored in the system (and therefore not queryable). The context of this hook distinguishes between the list of unsigned orders from the clinician's ordering session, and the one or more orders just added to this list. The selections field contains a list of ids of these newly selected orders; the draftOrders Bundle contains an entry for all unsigned orders from this session, including newly selected orders.

Field Optionality Prefetch Token Type Description
userId REQUIRED Yes string The id of the current user.
For this hook, the user is expected to be of type Practitioner or PractitionerRole.
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
selections REQUIRED No array The FHIR id of the newly selected order(s).
The selections field references FHIR resources in the draftOrders Bundle. For example, MedicationRequest/103.
draftOrders REQUIRED No object A Bundle of FHIR request resources with a draft status, representing orders that aren't yet signed from the current ordering session.

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
