Act Mood and Inert Vs. Descriptive Properties of Acts

Introduction

Question - How does the "isDocumentCharacteristic" property adopted to clarify negation intersect with the way that attribute interpretations "morph" in different moods. Arises because "status code" is considered part of a criterion description, rather than the status of the criterion Act itself. Have same issue around participations.

The RIM still discusses inert vs. descriptive properties as it relates to mood, but it does not clearly indicate what attribues are inert vs. descriptive. The RIM is also contradictory regarding what participations are considered inert vs. descriptive. Finally, what happens to participations that are conducted into a Criteria act, can they change from one to the other when conducted into the criteria act?

It's my understanding that act.statusCode is an inert attribute of an act, meaning that it does not follow the mood of the act, rather it is a property of the class itself. Act.statusCode represents the state of the underlying object. If statusCode is used as suggested in the eMeasure ballot, then we can never unambiguously communicate about the state of the act criteria object, i.e., we can't document it in new, vs. active, vs. suspended, vs. nullified, vs. completed.

  • Participation RIM inconsistency
    • The RIM in one place, documenting act.negationInd, states:
      • The negationInd negates the Act as described by the descriptive properties (including Act.code, Act.effectiveTime, Observation.value, Act.doseQty, etc.) and any of its components. The inert properties such as Act.id, Act.moodCode, Act.confidentialityCode, and particularly the Author-Participation are not negated.
    • In RIM documentation for act.moodCode it states:
      • In Event Criterion (not to be confused with Criterion) mood, an author considers a certain class of "obtaining blood glucose" possibly with a certain value (range) as outcome. The Participations constrain the criterion, for instance, to a particular patient.

We may have closed this for actionNegationInd, but clearly have not done so around criterion. This is most obvious for Mood codes under _ActMoodPredicate.

This is directly related to the previous Inert vs. descriptive properties of Acts Closed Hot Topic.

Resolution

January 2010 WGM, Sunday Q3

These issues were addressed via an approved harmonization proposal to introduce new .CRT mood codes. As well, all attributes and associations have been updated to identify which are inert and descriptive.
