Data elements that meet criteria using this datatype should document the laboratory test indicated by the QDM category and its corresponding value set was performed.
Timing:
- relevant dateTime references the time the laboratory test is performed when the laboratory test occurs at a single point in time.
- relevantPeriod references a start and stop time for a laboratory test that occurs over a time interval. relevantPeriod addresses:
- startTime - The time the laboratory test begins.
- stopTime - The time the laboratory test ends.
- author dateTime references the time the action was recorded.
- Refer to the eCQM expression to determine allowable timings to meet measure criterion.
Examples:
- Initiation of a venipuncture for a fasting blood glucose to the time venipuncture for the fasting blood glucose is completed – use relevant dateTime to reference this single point in time for many specimen collections
- Initiation of a 24-hour urine collection for measured creatinine clearance until completion of the 24-hour urine collection – use relevantPeriod to reference the start to stop time for this event.
Notes:
- The time that the result report is available is a separate attribute than the time of the study (specimen collection).
- 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.
