Due to the federal government shutdown, the eCQI Resource Center has paused updates to site information including announcement requests. The digital Quality Measure (dQM) public comment period is also paused and will resume once normal government operations restart. The comment deadline will be extended to account for the length of the shutdown.

["Laboratory Test, Performed": "Bicarbonate lab test"]
Performance/Reporting Period
2021
Value Set Description from VSAC
Clinical Focus: This value set contains codes for lab tests commonly used for a blood/serum/plasma bicarbonate lab test.
Data Element Scope: This value set may use the Quality Data Model (QDM) datatype Laboratory Test, Performed. The intent of this data element is to identify patients who had a Bicarbonate lab test on a specimen source of blood/serum/plasma.
Inclusion Criteria: Includes only codes that represent bicarbonate lab test using the specimen source of blood/serum/plasma. Includes codes that represent both bicarbonate and carbon dioxide lab tests.
Exclusion Criteria: Excludes any codes which do not represent bicarbonate lab tests using a non-blood/serum/plasma source of blood.

Constrained to codes in the Laboratory Test, Performed: Bicarbonate lab test value set (2.16.840.1.113762.1.4.1045.139)
QDM Datatype and Definition
"Laboratory Test, Performed"
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.
A QDM Known Issue has been identified related to this datatype. To see this QDM known Issue, please click here.
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.
