["Laboratory Test, Performed": "Human Immunodeficiency Virus (HIV) Laboratory Test Codes (Ab and Ag)"]

Performance/Reporting Period
2021
Value Set Description from VSAC
Clinical Focus: This value set contains concepts that represent laboratory tests used for Human Immunodeficiency Virus screening.
Data Element Scope: This value set may use the Quality Data Model (QDM) datatype related to Laboratory Test. Used for HIV screening.
Inclusion Criteria: Includes only relevant concepts associated with laboratory tests for HIV-1 and HIV-2 antibodies or antigens.
Exclusion Criteria: Excludes tests and procedures that might be associated with HIV infection that are not used for screening or testing to establish an HIV diagnosis, which would include home/self HIV testing, HIV genotyping tests, HIV RNA tests, HIV cultures, clinical codes used to document care provided to HIV-infected patients.

Constrained to codes in the Laboratory Test, Performed: Human Immunodeficiency Virus (HIV) Laboratory Test Codes (Ab and Ag) value set (2.16.840.1.113762.1.4.1056.50)

QDM Datatype and Definition (QDM Version 5.5 Guidance Update)

"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.

relevantDateTime

Relevant dateTime addresses the time an activity occurs as a single point in time. If the activity occurs over a period of time, use Relevant Period.
