1	cdmTableName	cdmFieldName	isRequired	cdmDatatype	userGuidance	etlConventions	isPrimaryKey	isForeignKey	fkTableName	fkFieldName	fkDomain	fkClass
2	episode	episode_id	Yes	bigint	A unique identifier for each Episode.		Yes	No
3	episode	person_id	Yes	bigint	The person_id of the person for whom the episode is recorded.		No	Yes	person	person_id
4	episode	episode_concept_id	Yes	integer	The episode_concept_id represents the kind abstraction related to the disease phase, outcome or treatment.	Choose a concept in the Episode domain that best represents the ongoing disease phase, outcome, or treatment. Please see [article] for cancers and [article] for non-cancers describing how these are defined. [Accepted Concepts](https://athena.ohdsi.org/search-terms/terms?domain=Episode&page=1&pageSize=15&query=)	No	Yes			Episode
5	episode	episode_start_date	Yes	date	The date when the Episode beings.	Please see [article] for how to define an Episode start date.	No	No
6	episode	episode_start_datetime	No	datetime	The date and time when the Episode begins.		No	No
7	episode	episode_end_date	No	date	The date when the instance of the Episode is considered to have ended.	Please see [article] for how to define an Episode end date.
8	episode	episode_end_datetime	No	datetime	The date when the instance of the Episode is considered to have ended.		No	No
9	episode	episode_parent_id	No	bigint	Use this field to find the Episode that subsumes the given Episode record. This is used in the case that an Episode are nested into each other.	If there are multiple nested levels to how Episodes are represented, the episode_parent_id can be used to record this relationship.	No	No
10	episode	episode_number	No	integer	For sequences of episodes, this is used to indicate the order the episodes occurred. For example, lines of treatment could be indicated here.	Please see [article] for the details of how to count episodes.	No	No
11	episode	episode_object_concept_id	Yes	integer	A Standard Concept representing the disease phase, outcome, or other abstraction of which the episode consists. For example, if the episode_concept_id is [treatment regimen](https://athena.ohdsi.org/search-terms/terms/32531) then the episode_object_concept_id should contain the chemotherapy regimen concept, like [Afatinib monotherapy](https://athena.ohdsi.org/search-terms/terms/35804392).	Episode entries from the 'Disease Episode' concept class should have an episode_object_concept_id that comes from the Condition domain. Episode entries from the 'Treatment Episode' concept class should have an episode_object_concept_id that scome from the 'Procedure' domain or 'Regimen' concept class.	No	Yes	concept	concept_id	Procedure, Regimen
12	episode	episode_type_concept_id	Yes	integer	This field can be used to determine the provenance of the Episode record, as in whether the episode was from an EHR system, insurance claim, registry, or other sources.	Choose the episode_type_concept_id that best represents the provenance of the record. [Accepted Concepts](https://athena.ohdsi.org/search-terms/terms?domain=Type+Concept&standardConcept=Standard&page=1&pageSize=15&query=).	No	Yes	concept	concept_id	Type Concept
13	episode	episode_source_value	No	varchar(50)	The source code for the Episdoe as it appears in the source data. This code is mapped to a Standard Condition Concept in the Standardized Vocabularies and the original code is stored here for reference.		No	No
14	episode	episode_source_concept_id	No	integer	A foreign key to a Episode Concept that refers to the code used in the source.	Given that the Episodes are user-defined it is unlikely that there will be a Source Concept available. If that is the case then set this field to zero.	No	Yes	concept	concept_id
15	episode_event	episode_id	Yes	bigint	Use this field to link the episode_event record to its episode.	Put the episode_id that subsumes the episode_event record here.	No	Yes	episode	episode_id
16	episode_event	event_id	Yes	bigint	This field is the primary key of the linked record in the database. For example, if the Episode Event is a Condition Occurrence, then the condition_occurrence_id of the linked record goes in this field.	Put the primary key of the linked record here.	No	No
17	episode_event	episode_event_field_concept_id	Yes	integer	This field is the concept_id that identifies which table the primary key of the linked record came from.	Put the concept_id that identifies which table and field the event_id came from. [Accepted Concepts](https://athena.ohdsi.org/search-terms/terms?vocabulary=CDM&conceptClass=Field&page=1&pageSize=15&query=)	No	Yes	concept	concept_id	Metadata
18	measurement	modifier_of_event_id	No	bigint	If the Measurement record is related to another record in the database, this field is the primary key of the linked record.	Put the primary key of the linked record, if applicable, here.	No	No
19	measurement	modifier_of_field_concept_id	No	integer	If the Measurement record is related to another record in the database, this field is the concept_id that identifies which table the primary key of the linked record came from.	Put the concept_id that identifies which table and field the modifier_of_event_id came from.
