PatientIdentityHistory View
Loading
Identifies chain of PatientIDs that were merged into the current PatientID record. This view provides a slight API improvement over PatientMergeHistory as it also includes a LineNBR = 0 record which is the current PatientID record. Using this API, one can simply join to PatientIdentityHistory and get all valid PatientIDs associated with the patient record, including the current value.
This functionality allows analysts to take data exports that may contain PatientIDs that no longer exists in Epic.Patient.Patient and easily get the current PatientID record associated with that patient.
