QResearch is a database of anonymised health records of over 35 million patients being utilised to answer urgent questions about COVID-19 and inform the response to the pandemic. GP data from EMIS is linked to cancer, death, hospital, intensive care, and COVID-19 data from Public Health England, NHS Digital, and ICNARC.

QResearch is currently working on a number of projects to tackle the COVID-19 pandemic looking at; predicting the risk of adverse outcomes from COVID-19, COVID-19 vaccine uptake and safety, the association between COVID-19, ethnicity, and mortality, the impact of COVID-19 on the cancer diagnosis, obesity and smoking in relation to COVID-19 severity, and the economic costs of COVID-19 to healthcare.
