Question 1

What standard vocabularies does Tiviztech use for semantic mapping?

Accepted Answer

Tiviztech uses the standard vocabularies recommended by OHDSI: SNOMED-CT for diagnoses and clinical findings, RxNorm for medications, LOINC for laboratory results, ATC for therapeutic classification, and ICD-10 as a source vocabulary. Mapping is carried out with tools such as Usagi and specialised clinical review.

Question 2

What is Computerised System Validation (CSV) and why is it necessary?

Accepted Answer

Computerised System Validation (CSV) is a regulatory process that demonstrates a computer system is fit for its intended use in GxP environments. It includes Installation Qualification (IQ), Operational Qualification (OQ) and Performance Qualification (PQ). It is mandatory for EDC systems such as REDCap when used in clinical trials regulated by the FDA or the EMA.

Question 3

What technologies does Tiviztech use for ETL pipelines?

Accepted Answer

Tiviztech develops ETL pipelines with Python and R, using PostgreSQL as the target database, Docker/K8s for deployment infrastructure, and OHDSI ecosystem tools such as White Rabbit, Rabbit-in-a-Hat and Usagi for source data analysis and mapping.

Question 4

What EHDS requirements must a hospital in Spain meet?

Accepted Answer

Centres within the Spanish National Health System (SNS) will need to standardise their data under interoperable models (OMOP CDM, HL7 FHIR), implement data governance mechanisms, ensure data traceability and quality, and appoint health data officers. Tiviztech advises on the full technical preparation required for EHDS compliance.
