QDM Datatype and Definition

"Diagnostic Study, Performed"

Data elements that meet criteria using this datatype should document the completion of the diagnostic study indicated by the QDM category and its corresponding value set.

Timing:

  • relevant dateTime references the time the diagnostic study is performed if it occurs at a single point in time.
  • relevantPeriod references a start and stop time for an assessment that occurs over a time interval:
    • startTime - when the diagnostic study is initiated.
    • stopTime - when the diagnostic study is completed.
  • author dateTime references the time the action was recorded.
  • Refer to the eCQM expression to determine allowable timings to meet measure criterion.

Examples using relevantPeriod:

  • Initiation of a treadmill stress test to the time the treadmill stress test has completed
  • Initiation of the ultrasound study until completion of the ultrasound study

Note: negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod.
