NordDRG updating and maintenance processes
The annual maintenance and updating of the NordDRG system is performed according to agreed protocol and yearly timetable

The updating process of the NordDRG system
- NordDRG definition tables are directly based on the primary classifications and are designed to be readily accessible and transparent
- The Board of the Nordic Casemix Centre formally approves any proposed changes to the definition tables
- The updating process is carried out by qualified experts and staff to meet the needs of key stakeholders in NordDRG user countries.
- New DRGs and modified grouping rules or features are accepted only if they meet established clinical, statistical, and economic criteria
- Modifications are validated against clinical and financial data to ensure that both economic and clinical homogeneity are maintained or improved
- Regular updates to the NordDRG system are essential to reflect advances in clinical practice, revisions to primary classifications, and other changes within the healthcare system.
- The NordDRG system is designed to preserve comparability over time whenever possible
- The development of other international casemix systems is closely monitored for insights that may guide future enhancements to the NordDRG system
Development / innovation principles
- Experts from NordDRG user countries are invited to collaborate in joint projects
- Participating countries are expected to share their expertise in the casemix field with other NordDRG user countries
- The Board of the Nordic Casemix Centre supports the development and innovation related activities


Information sharing and educational principles
- The importance of information sharing has an increasing value for the NordDRG cooperation
- There is a clear need for education of different stakeholder groups within the NordDRG user countries
- Continuous information sharing and educational activities are part of a routine work
