The NHS England OpenSAFELY COVID-19 Service is a secure, transparent, open-source software platform for analysis of electronic health data. The system provides access to de-identified (pseudonymised) personal data to support Approved Users (academics, analysts, and data scientists) to undertake approved projects for COVID-19 research, COVID-19 clinical audit, COVID-19 service evaluation and COVID-19 health surveillance purposes.
The purposes for processing are to identify medical conditions and medications that affect the risk or impact of COVID-19 infection on individuals; this will assist with identifying risk factors associated with poor patient outcomes as well as information to monitor and predict demand on health services.
