The specifications for the two VTE eCQM measures state that the numerator includes documentation of a reason why no VTE prophylaxis was given between arrival and hospital admission. The CQL appears to use "FromDayOfStartOfHospitalizationToDayAfterAdmission" but it is unclear how this CQL statement relates to patients that are seen in the ED and/or admitted to Observation prior to Acute Care hospitalization Admission Date? Does "FromDayOfStartOfHospitalizationToDayAfterAdmission" include the presence of a reason for no VTE prophylaxis found when a patient is in the Emergency Department and/or during an Observation Encounter prior to Acute Care Inpatient Admission?
