ValueSet: ActUncertainty

Official URL: http://terminology.hl7.org/ValueSet/v3-ActUncertainty				Version: 2.0.0
Active as of 2014-03-26			Computable Name: ActUncertainty
Other Identifiers: id: urn:oid:2.16.840.1.113883.1.11.16899

A code indicating whether the Act statement as a whole, with its subordinate components has been asserted to be uncertain in any way.

Examples: Patient might have had a cholecystectomy procedure in the past (but isn’t sure).

Constraints: Uncertainty asserted using this attribute applies to the combined meaning of the Act statement established by all descriptive attributes (e.g., Act.code, Act.effectiveTime, Observation.value, SubstanceAdministration.doseQuantity, etc.), and the meanings of any components.

Discussion:This is not intended for use to replace or compete with uncertainty associated with a Observation.values alone or other individual attributes of the class. Such pointed indications of uncertainty should be specified by applying the PPD, UVP or UVN data type extensions to the specific attribute. Particularly if the uncertainty is uncertainty of a quantitative measurement value, this must still be represented by a PPD in the value and NOT using the uncertaintyCode. Also, when differential diagnoses are enumerated or weighed for probability, the UVP or UVN must be used, not the uncertaintyCode. The use of the uncertaintyCode is appropriate only if the entirety of the Act and its dependent Acts is questioned.

Note that very vague uncertainty may be thought related to negationInd, however, the two concepts are really independent. One may be very uncertain about an event, but that does not mean that one is certain about the negation of the event.

Explanation of the columns that may appear on this page:

Level	A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System	The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code	The code (used as the code in the resource instance)
Display	The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition	An explanation of the meaning of the concept
Comments	Additional notes about how to use the code
