      Thank you for your inquiry regarding CMS1074v2 and CMS1206v2, Excessive Radiation Dose or Inadequate Image Quality for Diagnostic Computed Tomography (CT) in Adults (Facility IQR) and Excessive Radiation Dose or Inadequate Image Quality for Diagnostic Computed Tomography (CT) in Adults (Facility OQR). Yes, AlaraCommon.CT Scan Qualifies is calling the function AlaraCommon.Qualifies for each type of scan with the appropriate noise and dose thresholds for the scan type. For your example, Qualifies"(Study, "Abdomen and Pelvis Low Dose", 64, 598), 64 is noiseThreshold Decimal and 598 is sizeDoseThresold Decimal and "Abdomen and Pelvis Low Dose" is the code.

      Please let us know if you have any outstanding questions.

    • CMS1074v2

      I have a few questions regarding Excessive Radiation Dose or Inadequate Image Quality for Diagnostic Computed Tomography (CT) in Adults (Facility IQR) (https://ecqi.healthit.gov/sites/default/files/ecqm/measures/CMS1074v2.html) and Excessive Radiation Dose or Inadequate Image Quality for Diagnostic Computed Tomography (CT) in Adults (Facility OQR) (https://ecqi.healthit.gov/sites/default/files/ecqm/measures/CMS1206v2.html) numerator logic.

       

      Numerator

      • "Qualified Scan with Values" CTScan
          where AlaraCommon."CT Scan Qualifies" ( CTScan )

       

      Referencing the following function:

      • AlaraCommon.CT Scan Qualifies(Study "Diagnostic Study, Performed")
      • "Qualifies"(Study, "Abdomen and Pelvis Low Dose", 64, 598)
          or "Qualifies"(Study, "Abdomen and Pelvis Routine Dose", 29, 644)
          or "Qualifies"(Study, "Abdomen and Pelvis High Dose", 29, 1260)
          or "Qualifies"(Study, "Cardiac Low Dose", 55, 93)
          or "Qualifies"(Study, "Cardiac Routine Dose", 32, 576)
          or "Qualifies"(Study, "Chest Low Dose", 55, 377)
          or "Qualifies"(Study, "Chest Routine Dose", 49, 377)
          or "Qualifies"(Study, "Cardiac High Dose or Chest High Dose", 49, 1282)
          or "Qualifies"(Study, "Head Low Dose", 115, 582)
          or "Qualifies"(Study, "Head Routine Dose", 115, 1025)
          or "Qualifies"(Study, "Head High Dose", 115, 1832)
          or "Qualifies"(Study, "Extremity", 73, 320)
          or "Qualifies"(Study, "Neck or Cervical Spine", 25, 1260)
          or "Qualifies"(Study, "Thoracic or Lumbar Spine", 25, 1260)
          or "Qualifies"(Study, "Simultaneous Chest and Abdomen and Pelvis", 29, 1637)
          or "Qualifies"(Study, "Simultaneous Thoracic and Lumbar Spine", 25, 2520)
          or "Qualifies"(Study, "Simultaneous Head and Neck Routine Dose", 25, 2285)
          or "Qualifies"(Study, "Simultaneous Head and Neck High Dose", 25, 3092)

       

      However AlaraCommon.CT Scan Qualifies references "Qualifies" and NOT "AlaraCommon.Qualifies(Study "Diagnostic Study, Performed", code System.Code, noiseThreshold Decimal, sizeDoseThreshold Decimal)

       

      AlaraCommon.Qualifies(Study "Diagnostic Study, Performed", code System.Code, noiseThreshold Decimal, sizeDoseThreshold Decimal)

      • Study.result ~ code
          and ( "Global Noise Value"(Study) >= noiseThreshold
              or "Size Adjusted Value"(Study) >= sizeDoseThreshold
          )

      Questions:

      1. My assumption is in function AlaraCommon.CT Scan Qualifies we should be referencing function AlaraCommon.Qualifies for "Qualifies"? Is this correct? If so, in a future release could this be more clear?
      2. If 1 is true is AlaraCommon.CT Scan Qualifies parameters for "Qualifies" missing a parameter?
      3. For example "Qualifies"(Study, "Abdomen and Pelvis Low Dose", 64, 598).  I assume 64 is noiseThreshold Decimal and 598 is sizeDoseThresold Decimal but there is no parameter for code System.Code. Should there be a value there and there should be an additional parameter in that string?
      4. What was the intent of code System.Code?
