Shared Health Specification and Guide Version 3.0 Revision C

Allows a reference to identify the target prescription, dispense or task by business identifier rather than URL

When this is present, the reference is typically omitted.

Usage Note: This provides the medication order identifier that the dispense is associated with

Usage Note: In the context of p160 and p200, PMS's will populate this identifier value with the appropriate value

Usage Note: In the context of p200, EMRs need to use this value to find the corresponding medication order in their local system in order to associate the incoming dispense it to.

Usage Note: In the context of p160, EMRs can use either this value or the MedicationOrder.identifier:EMR-id to find the corresponding medication order in their local system which is related to the medication order which is asking to be renewed.

Usage Note: The URL for this extension does not refer to an existing web-page as is a pre-adoption extension. Refer to the Shared Health implementation Guide for more information.

An Extension

Source of the definition for the extension code - a logical name or a URL.

Fixed value: http://hl7.org/fhir/StructureDefinition/extension-Reference.identifier

Allows a reference to identify the target prescription, dispense or task by business identifier rather than URL

When this is present, the reference is typically omitted.

Comments:

In the context of a p200 this will represent the mediation order identifier of the original electronic prescription (e110, e120, e162, e163, e180) which the dispense is associated with.

In the context of a p160 this will represent either the mediation order identifier of the original electronic prescription (e110, e120, e162, e163, e180) which is the dispense is associated with or it will be the pharmacies own medication order identifier when the dispense is associated with a previous non-electronic order (i.e. paper or fax).

Usage: EMR's should use the identifier.system and identifier.value to determine whether medication order relates to an order within the local application. The identifier.system value represents the application (application instance id) that assigned the identifier and identifier.value represents the actual medication order value. When the system value does NOT match the local application then this identifier was assigned by another application and should be treated like a non-electronic (i.e. paper or fax) order. When the system value matches the local application then this identifier was assigned by this application and the system should then proceed to find the value. If the value cannot be found it should be treated like a non-electronic (i.e. paper or fax) order. Only when both the system and value match a local medication order can the application treat it as a electronic medication order.
