      Thank you for your inquiry specific to CMS871v2 Hospital Harm – Severe Hyperglycemia. Both values are evaluated regardless of sort order to determine if at least one of them meets the measure’s criteria. For example, one of the ways to meet the measure’s initial population (IPP) is to have at least one blood glucose value >=200 mg/dL at any time during the encounter. The following scenarios meet the IPP criteria because at least one of the glucose test result values is 200mg/dL:

      Scenario 1:
      Inpatient hospitalization start datetime: 10/23/23 8:00am
      Inpatient hospitalization end datetime: 10/27/23 8:15am
      Glucose lab test relevant datetime: 10/24/23 8:00am Result: 199 mg/dL
      Glucose lab test relevant datetime: 10/24/23 8:00am Result: 200 mg/dL

      Scenario 2:
      Inpatient hospitalization start datetime: 10/23/23 8:00am
      Inpatient hospitalization end datetime: 10/27/23 8:15am
      Glucose lab test relevant datetime: 10/24/23 8:00am Result: 200 mg/dL
      Glucose lab test relevant datetime: 10/24/23 8:00am Result: 199 mg/dL

      We have data where there are two glucose labs with different results but identical relevantDatetime values.  The CQL specification says "When the sort elements do not provide a unique ordering (i.e. there is a possibility of duplicate sort values in the result), the order of duplicates is unspecified.".  CMS871v2 does not provide a second attribute to sort the data elements.  

      What is the intended behavior for this clause?
