Data elements that meet criteria using this datatype should document the Condition/Diagnosis/Problem and its corresponding value set. The onset dateTime corresponds to the implicit start dateTime of the datatype and the abatement dateTime corresponds to the implicit stop dateTime of the datatype. If the abatement dateTime is not present, then the diagnosis is considered to still be active. When this datatype is used with timing relationships, the criterion is looking for an active diagnosis for the time frame indicated by the timing relationships.

Timing: The prevalencePeriod references the time from the onset date to the abatement date.

Data elements that meet criteria using this datatype should document a request by a clinician or appropriately licensed care provider to an appropriate provider or organization to perform the diagnostic study indicated by the QDM category and its corresponding value set. The request may be in the form of a consultation or a direct order to the organization that performs the diagnostic study. Diagnostic studies are those that are not performed in the clinical laboratory. Such studies include, but are not limited to, imaging studies, cardiology studies (electrocardiogram, treadmill stress testing), pulmonary function testing, and vascular laboratory testing.

Timing: The time the order is signed; author dateTime.

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.

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 5.5 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 a request to a pharmacy to provide the medication indicated by the QDM category and its corresponding value set.

Timing:

• relevantPeriod addresses the time referenced in the dosage instruction indicating when the medication administration should start and end.
• In the initial publication of QDM 5.5, relevantPeriod referenced the validity period, i.e., the time period for which the ordered supply is authorized by the prescription authorizing the dispensing event.
• For clarification, see Appendix 6.4 with additional guidance for referencing relevantPeriod updating the definition for Medication, Order, "Medication Dispensed", and "Substance, Order".
• author dateTime references the date and time the medication order (prescription) is authored.

Notes:

• When calculating cumulative medication duration, the stopTime may be present directly in the medication order. If the stopTime is not available, the duration in days is the difference between the relevantPeriod start and stop times multiplied by (1 + the number of refills).
• 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 Appendix A (Section 5.7) for scenarios to consider in calculating cumulative medication duration.

The "Patient Characteristic Birthdate" should document the patient’s date of birth.

Timing: The "Patient Characteristic, Birthdate" is a single point in time representing the date and time of birth. It does not have a start and stop time.

Note: "Patient Characteristic Birthdate" is fixed to LOINC code 21112-8 (Birth date) and therefore cannot be further qualified with a value set.

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.

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

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

Timing:

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

Notes:

• Timing refers to a single instance of a physical examination activity. If a measure seeks to evaluate multiple physical examination activities over a period of time, the measure developer should use CQL logic to represent the query request.
• 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.
