OHDSI Denmark


The vision for establishing a Danish national OHDSI node is to help improve patient care through reliable evidence facilitated through the OMOP CDM with best practice methods and tools. The node will serve as a national forum where stakeholders can jointly identify needs and develop solutions needed to advance the OHDSI mission and vision and coordinate activities between national and international collaborators. A special emphasis will be made to identify common areas of expertise that will facilitate quality control processes that can ensure the highest possible health data quality for research and clinical implementation.  


  • Build the Danish OHDSI Denmark community
  • Establish national standards for data transformation into the OMOP CDM to support clinical grade evidence and support the use of OMOP standardization for the deployment of data-driven medicine
  • Advance the use of the OMOP CDM in Denmark and facilitate international collaboration
