QDM Datatype and Definition (QDM Version 5.4)

"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: The Relevant Period addresses:

  • startTime – when the diagnostic study is initiated
  • stopTime – when the diagnostic study is completed

Examples:

  • 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
QDM Attributes

relevantPeriod

Relevant Period addresses the time between the start of an action to the end of an action. Each datatype using relevant period defines specific definitions for the start and stop time for the action listed.

result

The final consequences or data collected from the datatype. Results can be used in four ways, to express: (1) That a result is present in the electronic record but any entry is acceptable. (2) A numerical result is reported directly as a value. Values may be integers or decimal numbers without units, or as a quantity with a value and units. Examples: 100 mg/dL for a lab test, 140 mmHg for blood pressure, as a percentage (actually a quantity with % as units), as a ratio (e.g., 1:4, 1:80). (3) A result that matches one of a specific set of coded concepts in a value set or a code that matches a direct reference code. (4) A result as a dateTime (Assessment, Performed and components). Note: Measures use Clinical Quality Language (CQL) logic to express the mathematical operators to constrain desired results to those above or below a certain threshold.
