Generated Narrative: CodeSystem dataelement-stringency This case-sensitive code system http://hl7.org/fhir/dataelement-stringency defines the following codes in an undefined hierarchy: Lvl Code Display Definition 1 comparable Comparable The data element is sufficiently well-constrained that multiple pieces of data captured according to the constraints of the data element will be comparable (though in some cases, a degree of automated conversion/normalization may be required). 2 fully-specified Fully Specified The data element is fully specified down to a single value set, single unit of measure, single data type, etc. Multiple pieces of data associated with this data element are fully comparable. 2 equivalent Equivalent The data element allows multiple units of measure having equivalent meaning; e.g. "cc" (cubic centimeter) and "mL" (milliliter). 2 convertable Convertable The data element allows multiple units of measure that are convertable between each other (e.g. inches and centimeters) and/or allows data to be captured in multiple value sets for which a known mapping exists allowing conversion of meaning. 3 scaleable Scaleable A convertable data element where unit conversions are different only by a power of 10; e.g. g, mg, kg. 1 flexible Flexible The data element is unconstrained in units, choice of data types and/or choice of vocabulary such that automated comparison of data captured using the data element is not possible.
Indicates the degree of precision of the data element definition.
The data element is sufficiently well-constrained that multiple pieces of data captured according to the constraints of the data element will be comparable (though in some cases, a degree of automated conversion/normalization may be required).
The data element is fully specified down to a single value set, single unit of measure, single data type, etc. Multiple pieces of data associated with this data element are fully comparable.
The data element allows multiple units of measure having equivalent meaning; e.g. "cc" (cubic centimeter) and "mL" (milliliter).
The data element allows multiple units of measure that are convertable between each other (e.g. inches and centimeters) and/or allows data to be captured in multiple value sets for which a known mapping exists allowing conversion of meaning.
A convertable data element where unit conversions are different only by a power of 10; e.g. g, mg, kg.
The data element is unconstrained in units, choice of data types and/or choice of vocabulary such that automated comparison of data captured using the data element is not possible.
