When an Encounter/Procedure/Observation/MedicationAdministration/MedicationStatement/Condition resource is read in, the job first tries to delete possible already existing records in OMOP CDM using `fhir_logical_id` or `fhir_identifier`. If the resource is marked as 'deleted', no further transfomation will be occured. Otherwise the read resource is processed as a new resource (analog bulk load).

If the resource is marked as 'deleted', no further transformation will be occurred. Otherwise, the read resource is processed as a new resource (analog bulk load).
The job checks whether the referenced Patient resource already exists in OMOP CDM. This is done in PERSON and table using `fhir_logical_id` or `fhir_identifier`. If the referenced Patient resource is not available in OMOP CDM, the read Encounter/Procedure/Observation/MedicationAdministration/MedicationStatement/Condition resource is skipped. If the referenced Patient resource already exists in OMOP CDM, the existing `person_id` will be used. After this step, the further processing of the read resource is done analog to bulk load.
