The following logic is invoked for all encounters where it should be invoked one encounter at a time:
_First Blood Glucose Within 1 Hour Prior To and 6 Hours After Encounter Start
First(["Laboratory Test, Performed": "Glucose Lab Test Mass Per Volume"] FirstBloodGlucose
with("Qualifying Encounter")InpatientEncounter
such that FirstBloodGlucose.relevantDatetime during Interval[(start of Global."HospitalizationWithObservation"(InpatientEncounter)- 1 hour),(start of Global."HospitalizationWithObservation"(InpatientEncounter)+ 6 hours)]
sort by relevantDatetime
)_

We saw a case with two encounters that each had BloodGlucose measurements in the time period between an hour before and 6 hours after the start of their hospitalizations.

• The BloodGlucose value was less than 1000 during 1 hour before to 6 hours after the start of the first encounter.
• The BloodGlucose was greater than 1000 during 1 hour before to 6 hours after the start of the second encounter.

The FIRST of these BloodGlucose is selected by the above logic, that occurs during the first encounter, yet is applied to all of the encounters. The greater than 1000 BloodGlucose is never chosen because all encounters are considered. Encounter 2 should have had a final state of DENEX. This affects the Overall outcomes calculation.

Denominator Exclusion logic for HH02 then uses the FIRST BloodGlucose value (<1000) to decide whether the first and second Encounter have a final state of DENEX:
_Encounter With First Blood Glucose Greater Than or Equal to 1000
"Qualifying Encounter" InpatientHospitalization
with "First Blood Glucose Within 1 Hour Prior To and 6 Hours After Encounter Start" FirstGlucoseResult
such that FirstGlucoseResult.result >= 1000 'mg/dL'_

A possible solution would be to change First Blood Glucose Within 1 Hour Prior To and 6 Hours After Encounter Start to a function with argument "Encounter, Performed" so that only Labs starting between 1 hour before to 6 hours after the specific encounter are considered when FIRST is chosen.
