QDM Datatype and Definition

"Assessment, Performed"

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

Timing:

  • relevant dateTime references timing for an assessment that occurs at a single point in time.
  • relevant Period references a start and stop time for an assessment that occurs over a time interval
  • author dateTime references the time the action was recorded.
  • Refer to the eCQM expression to determine allowable timings to meet measure criterion.

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.

QDM Attributes

iD

The identifier of a specific instance of any QDM data element. CQL logic uses the id reference to specify that a query expects a specific instance of an element to be retrieved.

See Section 5.8 for examples for using id to indicate specific instances of QDM data elements in CQL statements with the relatedTo attribute.

relevantDateTime

relevant dateTime addresses the time an activity occurs as a single point in time. If the activity occurs over a period of time, use relevantPeriod.

relevantPeriod

relevantPeriod addresses the time between the start of an action to the end of an action. Each QDM datatype using relevantPeriod defines specific definitions for the start and stop time for the action listed.

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

result

The final consequences or data collected from the datatype. results can be used in four ways to express:

  • That a result is present in the electronic record but any entry is acceptable
  • 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:
    • 100mg/dL for a lab test
    • 140 mmHg for blood pressure
    • as a percentage (actually as a quantity with % as units)
    • as a titer or ratio (e.g., 1:4, 1:80)
  • 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
  • A result as a dateTime ("Assessment, Performed" and components)
