    • A system reporting on CMS832, CMS529 and CMS844 may need to report (in QRDA I) the same data elements (e.g., ["Physical Exam, Performed": "Heart rate”]) differently for CMS832 as it would for CMS529 and CMS844.

      The logic for CMS832 is looking for the heart rate as a unitless decimal. The logic for CMS529 and CMS844 is looking for the heart rate as a quantity with a recommended unit of

      {Beats}

      /min. This also impacts the blood pressure readings, body temperature and respiratory rate.

      Its likely one would need to report a heart rate like this for CMS529 and CMS844

      Note that there is no default conversion of a quantity to decimal in CQL. A decimal can be converted to a unitless quantity.

      Should the 3 eCQMs use the same casting, either "result as Decimal" or "result as Quantity?"
