Hi Team,

Consider the below statements :

Global.EmergencyDepartmentArrivalTime(Encounter "Encounter, Performed") :
start of First(("HospitalizationLocations"(Encounter))HospitalLocation
        where HospitalLocation.code in "Emergency Department Visit"
        sort by start of locationPeriod
).locationPeriod

Global.HospitalDepartureTime(Encounter "Encounter, Performed") :
end of Last(("HospitalizationLocations"(Encounter))HospitalLocation
        sort by start of locationPeriod
).locationPeriod

Query :

We are checking the first and last datetime of same entity whether it is in encounter or in  location period to evaluate ED Departure with Transfer to Acute Care Facility Within 45 Minutes of Arrival condition.

Kindly let us know if this interpretation is correct.

Thank you.
