Definitions for the dhb extension.
| 1. Extension | |
| Definition | District Health Board relating to a NZ Healthcare Service, Location (Facility) or Patient (primary, physical home address). |
| 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())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| 2. Extension.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. Extension.extension | |
| Definition | An Extension |
| Control | 0..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 Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
| 4. Extension.url | |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |
| Fixed Value | http://hl7.org.nz/fhir/StructureDefinition/dhb |
| 5. Extension.value[x] | |
| Definition | NZ District Health Boards as defined in the NZ Health Provider Index Listing published by the NZ Ministry of Health each month. |
| Control | 0..1 |
| Binding | The codes SHALL be taken from District Health Board Identifer; other codes may be used where these codes are not suitable NZ HPI-ORG Values for DHBs |
| Type | CodeableConcept |
| [x] Note | See Choice of Data Types for further information about how to use [x] |
| Requirements | The NzDHB ValueSet should be used as this provides the correct NZ HPI-ORG ID for each of the 20 District Health Boards.The binding strength is extensible as this is the most suitable option for a Codeable Concept data type. |
| Example | Waikato DHB:<valueCodeableConcept xmlns="http://hl7.org/fhir"> <coding> <system value="https://standards.digital.health.nz/ns/dhb-code"/> <version value="1.0"/> <code value="G00027-C"/> <display value="Waikato"/> </coding> </valueCodeableConcept> |
