Data elements that meet criteria using this datatype should document that the encounter indicated by the QDM category and its corresponding value set is in progress or has been completed.

The "Encounter, Performed" participant references the primary participant.

Previous versions of QDM included an attribute principal diagnosis, defined as the condition that, after study, was determined to be the principal cause of the admission. QDM version 5.6 addresses that concept using the diagnosis rank=1.

Timing:

• The relevantPeriod addresses:
  • startTime - The time the encounter began (admission time).
  • stopTime - The time the encounter ended (discharge time).
• author dateTime references the time the action was recorded.
• Refer to the eCQM expression to determine allowable timings to meet measure criteria.

Notes:

• 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.
• The locationPeriod is an attribute of the attribute facility location that addresses:
  • startTime - the time the patient arrived at the location. The time the encounter began (admission time).
  • stopTime - the time the patient departed from the location.

Data elements that meet criteria using this datatype should document the laboratory test indicated by the QDM category and its corresponding value set was performed.

Timing:

• relevant dateTime references the time the laboratory test is performed when the laboratory test occurs at a single point in time.
• relevantPeriod references a start and stop time for a laboratory test that occurs over a time interval. relevantPeriod addresses:
  • startTime - The time the laboratory test begins.
  • stopTime - The time the laboratory test ends.
• author dateTime references the time the action was recorded.
• Refer to the eCQM expression to determine allowable timings to meet measure criterion.

Examples:

• Initiation of a venipuncture for a fasting blood glucose to the time venipuncture for the fasting blood glucose is completed – use relevant dateTime to reference this single point in time for many specimen collections
• Initiation of a 24-hour urine collection for measured creatinine clearance until completion of the 24-hour urine collection – use relevantPeriod to reference the start to stop time for this event.

Notes:

• The time that the result report is available is a separate attribute than the time of the study (specimen collection).
• 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.

Data elements that meet criteria using this datatype should document that the medication indicated by the QDM category and its corresponding value set was actually administered to the patient.

Timing:

• relevant dateTime references the time the medication is administered if it was given or taken at a single point in time.
• relevantPeriod references a start and stop time for medication administration if the administration event occurred over a time interval (e.g., an intravenous infusion). The relevantPeriod addresses:
  • startTime - when a single medication administration event starts (e.g., the initiation of an intravenous infusion).
  • stopTime - when a single medication administration event ends (e.g., the end time of the intravenous infusion).
• author dateTime references the time the action was recorded.
• Refer to the eCQM expression to determine allowable timings to meet measure criterion.

Notes:

• Measure developers should address multiple administrations over a period of time using CQL logic.
• 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.

Refer to Special Cases in Section 5.7 for scenarios to consider in calculating cumulative medication duration.

Data elements that meet criteria using this datatype should document that the patient has one or more of the ethnicities indicated by the QDM category and its corresponding value set.

Timing: Ethnicity does not have a specific timing. Measures using "Patient Characteristic, Ethnicity" should address the most recent entry in the clinical record.

Data elements that meet criteria using this datatype should document that the patient has one or more of the payers indicated by the QDM category and its corresponding value set.

Timing:

The relevantPeriod addresses:

• startTime – the first day of insurance coverage with the referenced payer.
• stopTime – the last day of insurance coverage with the referenced payer.

Data elements that meet criteria using this datatype should document the patient’s race.

Timing: Race does not have a specific timing. Measures using "Patient Characteristic, Race" should address the most recent entry in the clinical record.

Data elements that meet criteria using this datatype should document that the patient's sex matches the QDM category and its corresponding value set.

Timing: Birth (administrative) sex does not have a specific timing.
