Definitions for the codexrt-radiotherapy-uniform-fractionation extension.
Guidance on how to interpret the contents of this table can be found here.
| 1. Extension | |
| Definition | This flag is true if the fractionation was uniform (i.e., treated with same modality and dose per fraction) and false if the fractionation was mixed. Treatment technique may vary in uniform fractionation. If the fractionation was uniform, then the correspondence between the physical and biologically effective dose can be determined at the course level. If the fractionation was not uniform, then the correspondence between the physical and biologically effective dose has to be determined per the phase level. The flag was introduced to support determination of whether fractionation was uniform when viewing the Radiotherapy Course Summary (without first checking the details of each treatment phase). This is important in registry use cases to efficiently assess whether checking phase level information is needed. Optional Extension Element - found in all resources. |

| Control | 0..1* 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.extension | |
| Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element. 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 can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Control | 0..0* |
| Type | Extension |
| Summary | false |
| Alternate Names | extensions, 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. |
| 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:
|
| 3. Extension.url | |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| XML Representation | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 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/fhir/us/codex-radiation-therapy/StructureDefinition/codexrt-radiotherapy-uniform-fractionation |
| 4. Extension.value[x] | |
| Definition | Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |
| Control | 0..1 |
| Type | Choice of: boolean, date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, Coding, SampledData, id, positiveInt, Distance, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, CodeableConcept, ParameterDefinition, dateTime, code, string, Contributor, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, Expression, Signature, unsignedInt, time |
