Definitions for the ext-task-group-identifier Extension

1. Extension
Definition

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. Refer to the PrescribeIT® Version 5.0 Jurisdictional Rules and Task Grouping Excel spreadsheet rules for a full set of scenarios.

Definition

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

8. Extension.value[x]:valueIdentifier.extension
Definition

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.

Alternate Namesextensions, user content
Comments

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.

9. Extension.value[x]:valueIdentifier.use
Definition

The purpose of this identifier.

Control0..1
BindingThe codes SHALL be taken from IdentifierUse Identifies the purpose for this identifier, if known .

Typecode
Is Modifiertrue
Requirements

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

Comments

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.

10. Extension.value[x]:valueIdentifier.type
Definition

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

Control0..1
BindingThe codes SHALL be taken from Identifier Type Codes; other codes may be used where these codes are not suitable A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.

TypeCodeableConcept
Requirements

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

Comments

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.

11. Extension.value[x]:valueIdentifier.system
Definition

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

Control1..1
Typeuri
Must Supporttrue
Requirements

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.

Example
General:http://www.acme.com/identifiers/patient or urn:ietf:rfc:3986 if the Identifier.value itself is a full uri
InvariantsDefined on this element
groupIdentifier-branch-3: This must be an OID ending in .3 (: $this.matches('^urn\\:oid\\:(\\d+\\.)+3$'))
12. Extension.value[x]:valueIdentifier.value
Definition

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

Control1..1
Typestring
Must Supporttrue
Comments

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.

14. Extension.value[x]:valueIdentifier.assigner

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.
