The Covid-19 Research Data Commons (CoRDaCo) is an efficient, effective way of quickly generating datasets for Covid-19 related research. CoRDaCo integrates multiple sources of clinical and social determinants data into one central repository, which can be leveraged for many uses. Creating a curated collection of data elements specific to Covid-positive patients and stored in a structured way allows for rapid creation of study-specific data sets.

Additionally, creating this central repository allows for use of applications that will give researchers direct access to generate data sets.

CoRDaCo leverages Regenstrief’s unique access to clinical elements from a variety of sources, utilizing data from the health information exchange, state laboratory reporting, and direct access to the electronic health records of two health systems.
