Hi Team,

Consider the below definition:

SDE Oxygen 60 Minutes Or Less Prior To ED Admission Or During ED 

"Initial Population"  InpatientEncounter
   let LastEDVisit: LastEDEncounter(InpatientEncounter),
    Oxygen: (["Intervention, Order": "Non Invasive Oxygen Therapy by Nasal Cannula or Mask"] 
     union ["Intervention, Performed": "Non Invasive Oxygen Therapy by Nasal Cannula or Mask"]
      union ["Device, Order": "Non Invasive Oxygen Therapy Device Codes"]) Oxygen
       where (Coalesce (start of Global."NormalizeInterval"(Oxygen.relevantDatetime, Oxygen.relevantPeriod), Oxygen.authorDatetime) during LastEDVisit.relevantPeriod
         or Coalesce (start of Global."NormalizeInterval"(Oxygen.relevantDatetime, Oxygen.relevantPeriod), Oxygen.authorDatetime) 60 minutes or less before or on start of LastEDVisit.relevantPeriod)

 
Query:

The above statement appears to be non-referenced by any of the Initial Patient Population definitions or downstream logic within the measure. 

Could you please confirm if the above statement is a part of measure logic. 

If it is intended to be included, how should it be evaluated using AND or OR logic? 

Request you to respond at the earliest as our client deliverables are dependent on it.
