PrescribeIT® Specification and Guide Version 5.0

This is the common identifier that represents a paper order. It may be shared by multiple Task instances for various Medication Orders, reflecting multiple requests that are authorized simultaneously for a patient by a single prescriber

Usage Note: This business identifier is assigned by the sending application and is used to group tasks together that need to be processed and managed together. The following scenarios provide further detail:

Scenario 1) Single Task allowed within a Bundle: There are some business scenarios where a given task will be managed individually and only a single task is allowed in a bundle. This is true for the Adapt (p170) and the Pharmacist Prescribe (p190). Multiple tasks of the same type are not allowed, nor are any other task type.

Scenario 2) Single Task is sent. For any task type, the source system may send a single task within the bundle.

Scenario 3) In either scenario 1 or 2, the task will be assigned its own Group Identifier and will be handled as a group of one.

Scenario 4) Bundle restricted to same task type only: There are cases when only tasks of the same type can be grouped together. This is true for the cancel request (e140), Dispense Notifications (p200), Cancel RX Dispense Notification (p210). In this scenario, no other task types are allowed within the bundle.

Scenario 5) Same or Mixed Task Types within a single group: There are cases when either all the tasks within a group happen to have the same task type (p160) which are not necessary restricted due to 4 or certain task types that are different can be grouped together. This is true for new (e110) and renewal (e120) where these are part of the same prescription. Another scenario is that renewal responses (e161, e162, e163, e164) may be sent with an e110 and/or an e120.

Scenario 6) In either scenario 4 and 5, the same Group Identifier must be assigned to the multiple tasks as they are all part of the same group. All task resources sharing a Group Identifier must be transmitted in the same message bundle and should be treated as a group by the receiving system.

Scenario 7) The p160 task type can only be sent within it's own bundle.

Multiple Group Identifiers within the same Bundle is not allowed.

The Task.extension:groupIdentifier.valueIdentifier.system element will be an OID of the form [Vendor root].[Application instance node].3 expressed as a uri (e.g. urn:oid:1.2.3.4). The branch “.3” is appended to create a unique namespace for the Group Identifer. The Task.extension:groupIdentifier.valueIdentifier.value element will be assigned by the sending system and must be a unique business identifier.

An Extension

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

Fixed value: http://hl7.org/fhir/StructureDefinition/extension-Task.groupIdentifier

Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).

• type @ $this

The group that this particular task was initiated as part of

Links multiple separate MedicationOrder, DeviceRequest and other requests that originated at the same time. In PrescribeIT® v2.0, this was formerly called Requisition Identifier.

unique id for the element within a resource (for internal references).

May be used to represent additional information that is not part of the basic definition of the element. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

The purpose of this identifier.

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one. Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

Allows users to make use of identifiers when the identifier system is not known.

This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

Establishes the namespace in which set of possible id values is unique.

There are many sequences of identifiers. To perform matching, we need to know what sequence we're dealing with. The system identifies a particular sequence or set of unique identifiers.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension.

Time period during which identifier is/was valid for use.

Organization that issued/manages the identifier.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.
