    Introduction

    -

    This tables below contain an overview of which standard OHDSI tools -make use of which OMOP CDM fields. The goal is to inform ETL developers, -tooling developers and CDM extensions.

    -
      -
    • For ETL developers it helps to have guidance on which fields to -prioritise in the mapping. Most value will be gained from populating -fields support across the OHDSI tooling.
      • -
    • For OHDSI tooling developers, this page provides insight in the gaps -of support and can drive future development efforts.
      • -
    • For CDM extensions, it helps to known what it means for an OMOP CDM -table/field to be part of the standard. In other words: what OHDSI -tooling do we at least expect to support the new extensions?
      • -
    -

    Currently four OHDSI tools have been evaluated: DataQualityDashboard, -Achilles, Atlas (Data Sources and Cohort creation) and Feature -Extraction.

    ToolSupports CDM Field ifLink to resource used
    DataQualityDashboardPart of Field Level checkshttps://github.com/OHDSI/DataQualityDashboard/blob/main/inst/csv/OMOP_CDMv5.4_Field_Level.csv
    AchillesCovered by at least one Achilles analysishttps://github.com/OHDSI/Achilles/blob/main/inst/csv/achilles/achilles_analysis_details.csv
    Atlas Data SourcesA statistic based on the field is shown in a ‘Data Sources’ -visualisationhttps://atlas-demo.ohdsi.org/
    Atlas CohortUsed in te Atlas User Interface for cohort definition criteria -(directly, or via ‘Add attribute’)https://atlas-demo.ohdsi.org/
    Feature ExtractionUsed in one of the Feature Extraction analyseshttps://github.com/OHDSI/FeatureExtraction/blob/main/inst/csv/
    -

    General criteria: - ✔️ if the field essential for OMOP CDM definition -(Primary Key, Foreign Key) e.g. person_id not explicitly used, but -essential. (if the PK is marked as False, it typically means the whole -table is not used in the tool e.g. _source_value fields -that are used for traceability in ETL) - ❗ if field is used by the -tool, but not in a meaningful way. e.g. provider_id in -Achilles only checked for a valid foreign key to the provider table.

    By Maxim Moinat and the Themis Working Group

    +

    The Themis Working Group convened on October 6th and December 7th +2023 to discuss the creation this convention for creating custom +concepts.

    +
    +

    Introduction

    +

    While the OMOP vocabularies are very comprehensive, it is not always +possible to use concepts existing in the OMOP vocabularies. For example, +when using a vocabulary that is only used in your institution or having +custom defined variables. In these cases, custom concepts can be used. +Custom concepts are concepts that are not part of the OMOP vocabularies, +and are only used in your institution. There are two main reasons to +define custom concepts in your local OMOP CDM vocabulary. The first is +that they are available in your local Atlas instance, which has several +use cases: - When viewing a standard concept, you can see which custom +concepts are mapped to it. This allows you to better understand what the +standard concept represents in your institution. - You can search for a +custom concept and find which standard concepts it is mapped to, to +include in your standard concept set. - For studies only using your +local data, you can define cohorts using custom concepts (through ‘Add +attribute’->‘Add … Source Concept’). The second reason is using the +custom concepts in your ETL. By creating both the custom concept, and +the ‘Maps to’ relationship (example below), we can use this in the same +way as mapping other source vocabularies.

    +

    Custom concepts are only defined locally. These cannot be +used for network research. Therefore it remains very important to map to +standard concepts.

    +
    +
    +

    Conventions

    +

    It is important to follow a set of conventions when creating custom +concepts, to avoid negatively impacting network studies. The conventions +are as follows:

    +
      +
    • Custom concepts have a concept_id larger than +2,000,000,000. This is to avoid clashes with existing +concepts.†
      • +
    • Custom concepts are always non-standard +(concept.standard_concept = NULL).
      • +
    • Custom concepts can only be used in the +_source_concept_id fields +(e.g. procedure_source_concept_id)
      • +
    • If the field _source_concept_id does not exist, add a +custom column to your table (e.g. a +drug_exposure.route_source_concept_id)1. If +there is a wide need in the community, a proposal can be submitted to +the CDM Working Group to add these fields in a future OMOP CDM +version.
      • +
    • Always add custom concepts to a new vocabulary specifically for your +source (see example below). If you have a need to add concepts to an +existing vocabulary, please contact the OHDSI Vocabulary Working +Group.
      • +
    • Do NOT add custom concepts to the hierarchy of existing vocabularies +(either in the concept_ancestor table or +subsumes/is a relations in the +concept_relationship table). This is to avoid descendant +concepts to differ between sites.
      • +
    +

    In addition, it is recommended to follow these suggestions:

    +
      +
    • For the domain_id, choose an appropriate existing value +from the domain table (‘Condition’, ‘Drug’, ‘Procedure’, etc.). Note +that this determines the target table the concept can be used in.
      • +
    • For the concept_class_id, it is not required to create +new classes for your source vocabulary. To leave the class empty +explicitly, use class ‘Undefined’. It is also allowed to reuse existing +concept classes (e.g. SNOMED’s ‘Clinical Finding’ for conditions or +RxNorm drug classes ‘Ingredient’, ‘Clinical Drug’, ‘Branded Drug’ +etc.).
      • +
    • In the new vocabulary record, the vocabulary_concept_id +can be set to 0, as this is often not used in the OMOP CDM.
      • +
    • Create mappings between custom concepts and standard concepts. This +can be done by adding rows to the concept_relationship +table, with the Maps to relation. The reverse relation, +Mapped from, should also be added. This allows for easy +navigation between custom and standard concepts2. The ‘mapped +to’ concept should be a standard concept.
      • +
    • Officially, concept_hierarchy is only for standard +concepts. However, if you local use case requires this (e.g. for +selection of descendants of custom concepts), the custom concepts can be +added into their own, isolated, hierarchy. ## Example In this example, +we will add one custom concept for the ‘DHD Diagnose Thesaurus’. This is +a Dutch vocabulary, which is not part of the OMOP vocabularies. We will +add the concept ‘diabetes mellitus type 1’. This concept has a mapping +to the standard concept ‘Diabetes mellitus type 1 (disorder)’, +concept_id 3341872.
      • +
    +

    After creating these records, we can use the custom concept in our +ETL to populate the condition_source_concept_id field.

    Getting your vocabulary into the OMOP vocabularies

    +

    If you think your custom concepts are useful for others, you can +submit them to the OMOP vocabularies. This could be as a supported +source vocabulary (like ICD) or a new vocabulary with standard concepts +(like LOINC). This is a separate process from the conventions described +above. Please see the this +support page.

For example, when using a vocabulary that is only used in your institution or having custom defined variables. In these cases, custom concepts can be used. Custom concepts are concepts that are not part of the OMOP vocabularies, and are only used in your institution. +There are two main reasons to define custom concepts in your local OMOP CDM vocabulary. The first is that they are available in your local Atlas instance, which has several use cases: + - When viewing a standard concept, you can see which custom concepts are mapped to it. This allows you to better understand what the standard concept represents in your institution. + - You can search for a custom concept and find which standard concepts it is mapped to, to include in your standard concept set. + - For studies only using your local data, you can define cohorts using custom concepts (through 'Add attribute'->'Add ... Source Concept'). +The second reason is using the custom concepts in your ETL. By creating both the custom concept, and the 'Maps to' relationship (example below), we can use this in the same way as mapping other source vocabularies. + +**Custom concepts are only defined locally. These cannot be used for network research. Therefore it remains very important to map to standard concepts.** + +## Conventions + +It is important to follow a set of conventions when creating custom concepts, to avoid negatively impacting network studies. The conventions are as follows: + +- Custom concepts have a `concept_id` larger than 2,000,000,000. This is to avoid clashes with existing concepts.† +- Custom concepts are always non-standard (`concept.standard_concept = NULL`). +- Custom concepts can only be used in the `_source_concept_id` fields (e.g. `procedure_source_concept_id`) +- If the field `_source_concept_id` does not exist, add a custom column to your table (e.g. a `drug_exposure.route_source_concept_id`)1. If there is a wide need in the community, a proposal can be submitted to the CDM Working Group to add these fields in a future OMOP CDM version. +- Always add custom concepts to a new vocabulary specifically for your source (see example below). If you have a need to add concepts to an existing vocabulary, please contact the OHDSI Vocabulary Working Group. +- Do NOT add custom concepts to the hierarchy of existing vocabularies (either in the `concept_ancestor` table or `subsumes`/`is a` relations in the `concept_relationship` table). This is to avoid descendant concepts to differ between sites. + +In addition, it is recommended to follow these suggestions: + +- For the `domain_id`, choose an appropriate existing value from the domain table ('Condition', 'Drug', 'Procedure', etc.). Note that this determines the target table the concept can be used in. +- For the `concept_class_id`, it is not required to create new classes for your source vocabulary. To leave the class empty explicitly, use class 'Undefined'. It is also allowed to reuse existing concept classes (e.g. SNOMED's 'Clinical Finding' for conditions or RxNorm drug classes 'Ingredient', 'Clinical Drug', 'Branded Drug' etc.). +- In the new vocabulary record, the `vocabulary_concept_id` can be set to 0, as this is often not used in the OMOP CDM. +- Create mappings between custom concepts and standard concepts. This can be done by adding rows to the `concept_relationship` table, with the `Maps to` relation. The reverse relation, `Mapped from`, should also be added. This allows for easy navigation between custom and standard concepts2. The 'mapped to' concept should be a standard concept. +- Officially, `concept_hierarchy` is only for standard concepts. However, if you local use case requires this (e.g. for selection of descendants of custom concepts), the custom concepts can be added into their own, isolated, hierarchy. +## Example +In this example, we will add one custom concept for the 'DHD Diagnose Thesaurus'. This is a Dutch vocabulary, which is not part of the OMOP vocabularies. We will add the concept 'diabetes mellitus type 1'. This concept has a mapping to the standard concept 'Diabetes mellitus type 1 (disorder)', concept_id 3341872. + +After creating these records, we can use the custom concept in our ETL to populate the `condition_source_concept_id` field. + +### Custom vocabulary + +| Field | Value | +|-------|-------| +| vocabulary_id | DHD Diagnose Thesaurus | +| vocabulary_name | Dutch Hospital Data Diagnosethesaurus | +| vocabulary_reference | https://www.dhd.nl/producten-diensten/diagnosethesaurus/Paginas/diagnosethesaurus.asp | +| vocabulary_version | 2023-04-20 | +| vocabulary_concept_id | 0 | + +### Custom concept + +| Field | Value | +|-------|-------| +| concept_id | 2 000 000 001 | +| concept_name | diabetes mellitus type 1 | +| domain_id | Condition | +| vocabulary_id | DHD Diagnose Thesaurus | +| concept_class_id | Undefined | +| standard_concept | `NULL` | +| concept_code | 0000002630 | +| valid_start_date | 2017-08-01 | +| valid_end_date | 2099-12-31 | +| invalid_reason | `NULL` | + +### Mapping relationship + +| Field | Value | +|-------|-------| +| concept_id_1 | 2 000 000 001 | +| concept_id_2 | 3341872 | +| relationship_id | Maps to | +| valid_start_date | 2017-08-01 | +| valid_end_date | 2099-12-31 | +| invalid_reason | `NULL` | +| Field | Value | +|-------|-------| +| concept_id_1 | 3341872 | +| concept_id_2 | 2 000 000 001 | +| relationship_id | Mapped from | +| valid_start_date | 2017-08-01 | +| valid_end_date | 2099-12-31 | +| invalid_reason | `NULL` | + +See the [Source To Standard query](https://ohdsi.github.io/CommonDataModel/sqlScripts.html#Source_to_Standard) to map a code in the source data to a standard concept. + +## Getting your vocabulary into the OMOP vocabularies + +If you think your custom concepts are useful for others, you can submit them to the OMOP vocabularies.
