Destination Field	Source field	Logic	Comment field
visit_occurrence_id		Incremental integer. Unique value per finngenid + 117000000000 (offset).	Generated
person_id	finngenid	person_id from person table where person_source_value equals finngenid	Calculated
visit_concept_id		concept_id_2 from concept_relationship table where concept_id_1 equals visit_source_concept_id and relationship_id equals “Maps to”.	Calculated NOTE: 0 when visit_source_concept_id is NULL
visit_start_date		approx_visit_date is calculated by extracting the date from visit_start_datetime.	Calculated
visit_start_datetime	approx_event_datetime	Copied from approx_event_datetime	Copied
visit_end_date		copied from visit_start_date	Copied
visit_end_datetime		copied from visit_start_datetime	Copied
visit_type_concept_id		Set 32879 - ‘Registry’ for all	Calculated
provider_id	coding_system_oid	provider_id from provider table where coding_system_oid equals speciality_source_value.
care_site_id		Set 0 for all	Info not available
visit_source_value		String build as “SOURCE=KANTA;INDEX=”	Calculated
visit_source_concept_id		omop_concept_id from fg_codes_info where source equals “KANTA”	Calculated using the fg_codes_info table.
admitted_from_concept_id		Set 0 for all	Info not available
admitted_from_source_value		Set NULL for all	Info not available
discharged_to_concept_id		Set 0 for all	Info not available
discharged_to_source_value		Set NULL for all	Info not available
