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 are integrated daily from the hospital information system into an CDW in i2b2 format.
Data integrated in i2b2 are loaded every 4 months into an CDW in OMOP-CDM format. 80% of data is mapped to standard terminologies.
Event triggering registration

Event triggering registration of a person in the data source

Other

Event triggering registration of a person in the data source, other

Hospital visit (in and outhospital)

Event triggering de-registration of a person in the data source

Other

Event triggering de-registration of a person in the data source, other

Patient opposition to secondary use of data

Event triggering creation of a record in the data source

Hospital encounter (in-hospital and out-hospital)
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, possible linkage

Probabilistic matching based on identity traits
(https://doi.org/10.1093/jamiaopen/ooab005)

Linked data source 1

Pre linked

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

No

Data source, other

French death registry (open data)

Linkage strategy

Probabilistic

Linkage variable

Last names, First Name, Birth date, Gender, Birth location, Birth country, Date of death, Last visit date

Linkage completeness

The recall and precision of our linkage strategy is 97.5% and 99.97%
2/3 of known deaths are derived from this external database.
