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.

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.
