The Confidence 95 range of a measurable quantity.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
Source of the definition for the extension code - a logical name or a URL.
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.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R4/extensibility.html) for a list).
low.unit.exists() and high.unit.exists() and low.unit = high.unit
Additional content defined by implementations
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.
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 low limit. The boundary is inclusive.
If the low element is missing, the low boundary is not known.
Numerical value (with implicit precision)
The value of the measured amount. The value includes an implicit precision in the presentation of the value.
The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books).
Precision is handled implicitly in almost all cases of measurement.
PQ.value, CO.value, MO.value, IVL.high or IVL.low depending on the value
< | <= | >= | > - how to understand the value
Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology.
If there is no comparator, then there is no modification of the value
This is labeled as "Is Modifier" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value
How the Quantity should be understood and represented.
The unit should be the same as the unit of the quantity this applies to.
There are many representations for units of measure and in many contexts, particular representations are fixed and required. I.e. mcg for micrograms.
The identification of the system that provides the coded form of the unit.
Need to know the system that defines the coded form of the unit.
CO.codeSystem, PQ.translation.codeSystem
A computer processable form of the unit in some unit representation system.
The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system.
Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest.
PQ.code, MO.currency, PQ.translation.code
The high limit. The boundary is inclusive.
If the high element is missing, the high boundary is not known.
