QDM Datatype and Definition

"Medication, Order"

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.
  • author dateTime references the date and time the medication order (prescription) is authored.

Notes:

  • The medication order (prescription) is unlikely to indicate a relevantPeriod, the time period for which the ordered supply is to be administered/taken including all refills. Therefore, to determine the number of days covered by a single dispensing event, use the daysSupplied attribute and the relevant dateTime of the event to determine when the ordered medication will run out. If daysSupplied is not available, derive it from the supply (quantity of medication ordered) divided by the dosage (amount of medication to be taken at a single administration) times the frequency (number of units per time period – e.g., per day):
    daysSupplied = supply / (dosage x frequency)
    And multiply the daysSupplied per dispensing event multiplied by one plus the number of refills to determine the total daysSupplied ordered.
    daysSupplied x (1 + #refills)
    Starting with the relevant dateTime add the total daysSupplied (including refills) to determine when the ordered medication quantity will run out.
  • 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.
