Background

This is the CC-HIC data dictionary. It is a comprehensive overview of all the data elements contributed to CC-HIC. All data elements are mapped to standardised medical ontologies so that it is very clear on what a data element is and what it is not.

This data dictionary is to be used when writing the ETL process from your local hospital EHR to the standardised OHDSI version 6 format (often colloquially called OMOP for historical reasons)
