      The Measure resource already has a scoringUnit element that supports specifying the expected UCUM unit for the score:

      https://hl7.org/fhir/R5/measure-definitions.html#Measure.scoringUnit

      There is also an R4 extension defined in the QM IG that can be used for this purpose.

      Scoring precision, however, is not currently supported.

      Propose adding:

      scoringPrecision positiveInt 0..1 How many decimals (The number of decimal places to include in the score when the score is a decimal-valued result)

    Description

      There is no clarity what level of precision/rounding the MeasureReport.group.measureScore should be expressed, or when to express it as a percentage or fraction.  While that could be in the Measure.definition or Measure.guidance, that is not computable.

      Propose to add .scoringPrecision that indicates the number of decimals to include, and .scoringUnitOfMeasure or simply .scoringPercentage as a boolean enabling automatic population of the desired value.
