Data elements that meet criteria using this datatype should document completion of the assessment indicated by the QDM category and its corresponding value set.
- relevant dateTime references timing for an assessment that occurs at a single point in time.
- relevant Period references a start and stop time for an assessment that occurs over a time interval
- author dateTime references the time the action was recorded.
- Refer to the eCQM expression to determine allowable timings to meet measure criterion.
Note: 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.
