In VTE4 and VTE5 the following logic exists in the denominator:

AND:
OR: "Diagnostic Study, Result: VTE Diagnostic Test (result: 'VTE Confirmed')" <= 2 day(s) starts before start of "Occurrence A of Encounter, Performed: Inpatient Encounter"
OR: "Diagnostic Study, Result: VTE Diagnostic Test (result: 'VTE Confirmed')" during "Occurrence A of Encounter, Performed: Inpatient Encounter"
OR:
AND: "Occurrence A of Encounter, Performed: Inpatient Encounter (admission datetime)" <= 1 hour(s) starts after end of "Occurrence A of Encounter, Performed: Emergency Department Visit (facility location departure datetime)"
AND:
OR: "Diagnostic Study, Result: VTE Diagnostic Test (result: 'VTE Confirmed')" <= 2 day(s) starts before start of "Occurrence A of Encounter, Performed: Emergency Department Visit (facility location arrival datetime)"
OR: "Diagnostic Study, Result: VTE Diagnostic Test (result: 'VTE Confirmed')" during "Occurrence A of Encounter, Performed: Emergency Department Visit"
OR: "Diagnostic Study, Result: VTE Diagnostic Test (result: 'VTE Confirmed')" during "Occurrence A of Encounter, Performed: Inpatient Encounter"

The last line in this section of logic is redundant, since it is only looking for the VTE Diagnostic Test result, regardless of if there was a preceding ED encounter, they would already be included due to having a VTE Confirmed during the inpatient encounter.

(NOTE, the same extra logic in VTE3 is necessary due to the addition of the Warfarin check, so it should not be removed there.)
