Biospecimen access

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

Yes

Biospecimen access conditions

Hospital biobank can collect all kinds of biospecimen in different phases of the treatment based on patients' concent. E.g. DNA, serum, and plasma samples, fresh frozen tumor samples, SCF-samples and FFPE samples. https://helsinginbiopankki.fi

Access to subject details

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

Yes

Description of data collection

All patients who visit the hospital are recorded in our IT system. All visits, all procedures and given treatments have been recorded systematically in the electronic format. We use more than hundred different operational IT systems. For secondary use, the individual level data is pooled into a data lake. Data relevant for research is then collected through an ETL-process and provided to dedicated secure analytics environments for a specific research purpose (project). Furtehr, we have the OMOP mapping and ETL processes built in collaboration with the other Finnish University Hospitals and the Institute of Health and Welbeing (FinOMOP Consortium). Patient events are mainly of the following types: outpatient visit (with a specific start and end time), inpatient episodes (with a specific start and end time) or additional clinical events (lab, radiology, procedure) with specific timestamps. The observation period for a patient starts from the earliest event and end at the latest event.

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

Information about deaths.

Pre linked

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

No

Data source, other

Data from many nation-wide health registries such as drug purchase, visual impairment, cancer, retirement due to a disease registries and many others, can be combined to the Tampere University Hospital patient registry. The combination needs a specific research plan and data permit.
