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)?

Yes

Biospecimen access conditions

Request to the "Centro Risorse Biologiche" (CRB) which coordinates the activities of the POLI-MI biobank.

Access to subject details

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

No

Description of data collection

Every week a ETL procedure import automatically data from the Health Information System od the hospital (Hospitalization, Outpatients visits, Laboratory test, Therapies, Radiology and Anatomic Pathology) to an OMOP database
Event triggering registration

Event triggering registration of a person in the data source

Disease diagnosis
Other
Start of treatment

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

Laboratory tests or outpatients visits

Event triggering creation of a record in the data source

Outpatient: access to the hospitals: Inpatients: closure of hospitalization
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

For each hospitalization we search if that admission is subsequent of an ER access. In that case we link the ER access to the hospitalization visit.

Linked data source 1

Pre linked

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

Yes

Data source, other

ER (Emergency Room) - Hospitalization

Linkage strategy

Deterministic

Linkage variable

variable = data_dimissione, id_paz. Data dimissione = dimission's date from ER, id_paz = id of the patient

Linkage completeness

Only for patients that are hospitalized in the same day of an ER access
Data management specifications that apply for the data source

Data source refresh

Monthly

Informed consent for use of data for research

Required for intervention studies

Possibility of data validation

Can validity of the data in the data source be verified (e.g., access to original medical charts)?

Yes

Data source preservation

Are records preserved in the data source indefinitely?

No

Data source preservation length

30 years

Approval for publication

Is an approval needed for publishing the results of a study using the data source?

Yes

Data source last refresh

Common Data Model (CDM) mapping

CDM mapping

Has the data source been converted (ETL-ed) to a common data model?

Yes
