The grants awarded to data partners will be paid from the EHDEN Harmonization Fund. EHDEN foresees three different type of grants, depending on the current situation of the data partner:
- Full mapping
This activity is intended for data partners that have not mapped their data to the OMOP common data model (CDM) yet. It includes the data partner profiling, development and implementation of the extraction-transform-load (ETL) process and quality control assessments. Additionally, the EHDEN framework and OHDSI tools will be deployed at the local site and the data custodian will receive training. Finally, the data partner will be included in the Data Catalogue and can participate in the federated data network. This exercise can be supported by an SME that is certified by EHDEN or can be performed by the data partner itself if it fulfils the same certification requirements.
- Mapping Extension
This activity is intended for data partners that are already partially mapped to the CDM, to add additional domains (e.g. measurements, procedures) or add new partner vocabulary mappings. The financial support will also be used for quality assessment of the ETL, tool deployment, training, and the inclusion in the Database Catalogue. This activity would enable the already growing number of data partners that are being mapped in Europe to leverage the expertise in EHDEN to further improve and extend their CDM mapping.
- Mapping Validation
This activity consists of a standardized procedure developed in EHDEN which needs to be applied by a certified SME to ascertain the quality of the ETL and its documentation. Note that the quality ascertainment is not a requirement to be part of the data network, any data partner that is mapped to the CDM can participate. However, this financially supported activity is intended to inform others that the quality checks have been performed. If the quality of the mapping is below the standard the data partner could apply for additional funding to remedy this.
Overall, a maximum of 100.000 Euro per third party can be made available for financial support. The main aspect determining the actual amount of funding is the person hours spent on the mapping process by an SME or similar, which is largely dependent on the complexity of the data and the type of grant (full mapping, mapping extension, mapping validation). The following components will be taken into account when determining complexity:
- If the data source is in a data structure for which an adapter is already available (e.g. another CDM) the complexity of the mapping is assumed to be lower.
- If there are source vocabularies that are not yet available in the Standardized Vocabularies this will increase the complexity level.
- If the source data structure is not fully normalized (e.g. a single field has multiple meanings) this will increase the complexity level.
- The data domains that will be included in the activity will drive its complexity, for example measurements are much more complex than conditions.
