Access and validation

Governance details

Documents or webpages that describe the overall governance of the data source and processes and procedures for data capture and management, data quality check and validation results (governing data access or utilisation for research purposes).

Biospecimen access

Are biospecimens available in the data source (e.g., tissue samples)?

No

Access to subject details

Can individual patients/practitioners/practices included in the data source be contacted?

No

Description of data collection

Data collection for the national registers that provide data for the described data source, is the responsibility of the National Health Data Authority. Hospital data originate from electronic health records systems in all Danish hospitals. Filled prescriptions are reported from all danish pharmacies
Event triggering registration

Event triggering creation of a record in the data source

Any hospital encounter results in data being recorded in the national registers. Similarly, any filled prescription results in a record in the national prescription register
Data source linkage

Linkage

Is the data source described created by the linkage of other data sources (prelinked data source) and/or can the data source be linked to other data source on an ad-hoc basis?

Yes

Linkage description, pre-linked

Linkage by unique person identifier

Linked data source 1

Pre linked

Is the data source described created by the linkage of other data sources?

No

Data source, other

As our OMOP ETL is gradually expanded, we expect to be able to include additional Danish health registers into the data source. This could e.g. be the national causes of death register
