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: The Relevant Period addresses: startTime = when a single medication administration event starts (e.g., the initiation of an intravenous infusion, or administering a pill or IM injection to a patient); stopTime = when a single medication administration event ends (e.g., the end time of the intravenous infusion, or the administration of a pill or IM injection is completed - for pills and IM injections, the start and stop times are the same) NOTE – Measure developers should address multiple administrations over a period of time using CQL logic. Refer to Special Cases in Appendix A (Section A.3) for scenarios to consider in calculating cumulative medication duration.
