QDM Datatype and Definition (QDM Version 5.5 Guidance Update)

"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.


  • 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.


  • 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.
