      Thank you for bringing this issue to our attention. The measure construct of age at the time of the index event was intentional for this longitudinal outcome measure. It does not necessarily fit well the an age strategy for a process measure such as CMS137 whose focus is the initiation of treatment during the measurement period.

      The CQL stratification definition for CMS159 and CMS160 select the patients birth date as the element to stratify against but the measure itself is patient based (the population clauses select a bool).  CMS137 correctly performs stratification against the birth date for a patient based measure where it also returns a Boolean value.The CQL stratification definition for CMS159 and CMS160 select the patients birth date as the element to stratify against but the measure itself is patient based (the population clauses select a bool).  CMS137 correctly performs stratification against the birth date for a patient based measure where it also returns a Boolean value.

      CMS159 

       

      Stratification 1
["Patient Characteristic Birthdate"] Birthdate 
   with "Index Depression Assessment" IndexAssessment 
      such that Global."CalendarAgeInYearsAt"(Birthdate.birthDatetime, IndexAssessment.authorDatetime)>= 12 
      and Global."CalendarAgeInYearsAt"(Birthdate.birthDatetime, IndexAssessment.authorDatetime)< 18

      CMS137v7 

      Stratification 1
exists ( ["Patient Characteristic Birthdate"] BirthDate where Global."CalendarAgeInYearsAt"(BirthDate.birthDatetime, start of "Measurement Period")>= 13 and Global."CalendarAgeInYearsAt"(BirthDate.birthDatetime, start of "Measurement Period")< 18)

      Note the presence of the exists operator at the root of the CQL statement in 137 and it's absence in 159 and 160.
