CodeSystem: DataElementStringency

Official URL: http://hl7.org/fhir/dataelement-stringency Version: 3.0.2
Standards status: Trial-use Maturity Level: 1 Responsible: Orders and Observations Computable Name: DataElementStringency

Indicates the degree of precision of the data element definition.

This Code system is referenced in the content logical definition of the following value sets:

This case-sensitive code system http://hl7.org/fhir/dataelement-stringency defines the following codes in an undefined hierarchy:

LvlCodeDisplayDefinition
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.
