Constrained to codes in the Medication, Active: Low Intensity Statin Therapy value set (2.16.840.1.113883.3.526.3.1574)
"Medication, Active"
Data elements that meet criteria using this datatype should document that the medication indicated by the QDM category and its corresponding value set is being taken by the patient. Keep in mind that when this datatype is used with timing relationships, the criterion is looking for a medication being taken for the time frame indicated by the timing relationships.
Timing:
- relevant dateTime references the time the medication is active on the medication record if it was given or taken at a single point in time.
- relevantPeriod references a start and stop time for an active medication on the medication record that is given or taken over a time interval:
- The relevantPeriod addresses:
- startTime - when the medication is first known to be used (generally the time of entry on the medication list).
- stopTime - when the medication is no longer active.
In the original QDM 5.5 publication, stopTime stated: when the medication is discontinued (generally, the time discontinuation is recorded on the medication list). See Appendix 6.3 for clarification regarding definition of "Medication, Active" relevantPeriod stopTime.
relevantDateTime
relevantPeriod
Relevant Period addresses the time between the start of an action to the end of an action. Each datatype using relevant period defines specific definitions for the start and stop time for the action listed.
Note: negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatyperelated actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod
