The context of an existing act that is being referenced should not be modified by the reference.  Consequently, sourceOf1.contextConductionInd should never have a value of “true” but retaining the attribute (even with a default of “false”) allows an invalid value to be transmitted.

Issue

Need to be able to convey more information about the nature of the relationships between Clinical Statements

Recommendation

Add the following attributes to ActChoice.sourceOf1 and ActChoice.sourceOf2/targetOf:

  • inversionInd - cardinality [1..1], conformance Mandatory and default of “false”
  • negationInd - cardinality [1..1], conformance Mandatory and default of “false”
  • seperatableInd - cardinality [1..1], conformance Mandatory and default of “true”

Rationale

All of these attributes are used by NPfIT

  • inversionInd allows the semantic of the relationship to be reversed without changing the clinical statement that is the source act and hence the supplier of the context to the relationship
  • negationInd allows the semantic of the relationship to be negated (does NOT have Cause)
  • seperatableInd allows the sender to state that the source act should not be interpreted without referring to the target act.
