OHDSI Finland – National Node
Local Collaboration. European Impact.
FinOMOP is an initiative started in 2021 with the aim of creating and maintaining mappings to enable the use of the OMOP CDM in Finland. Currently the community provides knowledge and support for Finnish OMOP users and data partners.
FinOMOP and the OMOP common data model conversion projects started in 2019, funded by an EU IMI2 EHDEN data partnership and local funds. The first data partners to convert their data to OMOP were some of the Finnish university hospitals and FinnGen. In 2022, the Finnish Institute for Health and Welfare (THL) joined and helps to coordinate the effort.
Our vision is a comprehensive population-based health data infrastructure for Finland by 2025. Primary health care registries, specialist care data, and national genomic resources are being aligned to the OMOP CDM to support reliable, transparent, and real-time evidence generation by harmonized data applications.

Objectives
- Enable high-quality, granular mapping of key Finnish medical data sources to the OMOP CDM.
- Support comprehensive national coverage across primary, secondary, and specialist care.
- Hold regular FinOMOP meetings and task-specific meetings for the analytics, vocabulary, and extract-transform-load workgroups.
- Maintain a common mapping codebase through a shared GitHub repository and version-controlled USAGI files for each national vocabulary.
- Engage with and contribute to the OHDSI, EHDEN, and Nordic OMOP collaboration communities.

Focus areas
National priorities
- Mapping electronic medical records, governmental registries, and genome sequencing projects to the OMOP CDM
- Comprehensive population-based health data coverage in Finland
- Reliable, transparent, and real-time evidence generation through harmonized data applications
- National vocabulary mappings maintained through shared GitHub infrastructure
- Coordination of analytics, CDM, and vocabulary work
Current context
- Primary health care is covered by legislation-mandated population registries governed by the Finnish Institute for Health and Welfare (THL).
- Mapping of governmental registries has been initiated since 2022, including HILMO, avoHILMO, and FinRegistry.
- Secondary and tertiary care is covered by five university hospitals, with three out of five having completed OMOP conversion and covering more than 70% of the Finnish population.
- FinnGen, a national public-private partnership genome project covering 500,000 biobank participants, has adopted the OMOP CDM.
- ETL coding has been outsourced to EHDEN-certified SMEs.
