Definitions for the StructureDefinition-au-ihi Profile.
| 1. Identifier | |
| Definition | Individual Healthcare Identifier (IHI) assigned under the HI Service to a patient. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) inv-ihi-value-0: IHI shall be an exactly 16 digit number (: value.matches('^([0-9]{16})$')) inv-ihi-value-1: IHI prefix is 800360 (: value.startsWith('800360')) inv-ihi-value-2: IHI shall pass the Luhn algorithm check (: (((select(value.substring(0,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(1,1).toInteger())+(select(value.substring(2,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(3,1).toInteger())+(select(value.substring(4,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(5,1).toInteger())+(select(value.substring(6,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(7,1).toInteger())+(select(value.substring(8,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(9,1).toInteger())+(select(value.substring(10,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(11,1).toInteger())+(select(value.substring(12,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(13,1).toInteger())+(select(value.substring(14,1).toInteger()).select(iif($this<5, $this*2, (($this*2)-9))))+(value.substring(15,1).toInteger()))mod 10=0)) |
| 2. Identifier.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| 3. Identifier.extension | |
| Definition | An Extension |
| Control | 0..* |
| Type | Extension |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| Slicing | This element introduces a set of slices on Identifier.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
| 4. Identifier.extension:ihiStatus | |
| SliceName | ihiStatus |
| Definition | IHI number status associated with an IHI identifier. |
| Control | 0..1 |
| Type | Extension(IHIStatus) (Extension Type: Coding) |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| 5. Identifier.extension:ihiRecordStatus | |
| SliceName | ihiRecordStatus |
| Definition | Known IHI record status associated with an IHI identifier. |
| Control | 0..1 |
| Type | Extension(IHIRecordStatus) (Extension Type: Coding) |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| 6. Identifier.extension:ihiVerifiedDate | |
| SliceName | ihiVerifiedDate |
| Definition | The date, and optionally time, that the IHI was verified with HI Services. |
| Control | 0..1 |
| Type | Extension(IHIVerifiedDate) (Extension Type: dateTime) |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| 7. Identifier.use | |
| Definition | The purpose of this identifier. |
| Control | 0..1 |
| Binding | The codes SHALL be taken from IdentifierUse Identifies the purpose for this identifier, if known . |
| Type | code |
| Is Modifier | true |
| Requirements | Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers. |
| Comments | Applications can assume that an identifier is permanent unless it explicitly says that it is temporary. |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
| 8. Identifier.type | |
| Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose. |
| Control | 1..1 |
| Binding | The 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. |
| Type | CodeableConcept |
| 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. |
| Pattern Value | <valueCodeableConcept xmlns="http://hl7.org/fhir"> <coding> <system value="http://terminology.hl7.org/CodeSystem/v2-0203"/> <code value="NI"/> </coding> </valueCodeableConcept> |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
| 9. Identifier.system | |
| Definition | Establishes the namespace for the value - that is, a URL that describes a set values that are unique. |
| Control | 1..1 |
| Type | uri |
| Requirements | There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers. |
| Comments | Identifier.system is always case sensitive. |
| Fixed Value | http://ns.electronichealth.net.au/id/hi/ihi/1.0 |
| Example | General:http://www.acme.com/identifiers/patient |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
| 10. Identifier.value | |
| Definition | The portion of the identifier typically relevant to the user and which is unique within the context of the system. |
| Control | 1..1 |
| Type | string |
| 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. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe. |
| Max Length | 16 |
| Example | General:123456 IHI:8003608833357361 |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
| 11. Identifier.period | |
| Definition | Time period during which identifier is/was valid for use. |
| Control | 0..1 |
| Type | Period |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
| 12. Identifier.assigner | |
| Definition | Organization that issued/manages the identifier. |
| Control | 0..1 |
| Type | Reference(Organization) |
| Comments | 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. |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
