In the largest such study conducted in any country to date, academics at the University of Oxford and the London School of Hygiene & Tropical Medicine have analysed over 17 million COVID-19 patient records to better characterise the factors that put an individual at risk of dying from the disease. The study was published in the preprint journal medRxiv, and the main findings are as follows:
Data from patients hospitalised with COVID-19 was linked with GP records via the OpenSAFELY analytics platform. This system allowed the records to be linked where they are stored for individual care, lowering the security risks associated with transferring the data elsewhere. All identifiable data remains in control of the NHS and is pseudonymised researchers are able to access it.
In light of the findings, the authors suggest the increased risk to those from non-white backgrounds and deprived areas requires further investigation. They suggest that exploring occupational exposure and living conditions may provide a starting point for further studies.
