History description 2014-03-26: Lock all vaue sets untouched since 2014-03-26 to trackingId 2014T1_2014_03_26
description:
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<PQ> in
the value and NOT using the uncertaintyCode. Also, when differential diagnoses are
enumerated or weighed for probability, the
UVP<CD> or UVN<CD> 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.
