Minnesota Electronic Health Record Consortium COVID-19 Project Informing Pandemic Response Through Statewide Collaboration Using Observational Data

The authors developed a federated data network in March 2020 using electronic health record (EHR) data from 8 multispecialty health systems in Minnesota to track COVID-19 positivity rates by various demographic variables, including rurality, ethnicity, and language. This process demonstrated the ease and importance of developing similar syndromic surveillance systems using EHR data.
