November 2020 Working on behalf of NHS England, this paper used the OpenSAFELY platform to investigate the effectiveness of hydroxychloroquine for prevention, as opposed to treatment, of COVID-19 mortality. We found no evidence of benefit or harm after adjusting for important differences between people with the same health conditions prescribed hydroxychloroquine or not.

December 2020. Working on behalf of NHS England, this study investigates which people were switched from warfarin to DOACs following national guidance during the first wave of the COVID-19 pandemic; seeks to identify potentially unsafe co-prescribing of anticoagulants; and assesses whether abnormal clotting results have become more frequent during the pandemic.
November 2020. Working on behalf of NHS England, this study investigates whether risk of infection with SARs-CoV-2 and severe outcomes differed between adults living with and without children

October 2020. This protocol reports details of a planned study to explore the extent to which incorporating time-varying measures of infection burden over time improves the quality of risk prediction models for COVID-19 death in a large population of adult patients in England.
September 2020. Working on behalf of NHS England, the aim of this study was to identify ethnic differences in the risk of COVID-19 infection, hospitalisation and mortality using a large general population cohort in England.
August 2020 Working on behalf of NHS England, this paper used the OpenSAFELY platform to investigate the association between NSAID use and deaths from COVID-19. We found no evidence of a harmful effect of NSAIDs on COVID-19 related deaths. Risks from COVID-19 do not need to influence decisions about therapeutic use of NSAIDs.
Post-publications supplement to Williamson, E.J., Walker, A.J., Bhaskaran, K. et al. OpenSAFELY: factors associated with COVID-19 death in 17 million patients. Nature (2020). https://doi.org/10.1038/s41586-020-2521-4
August 2020. In the above paper, working on behalf of NHS England, we estimated associations between a wide range of individual-level factors including demographics and comorbidities, and risk of COVID-19 death, but we did not explore interactions between variables. It is plausible that associations may depend on age, and evaluating this would inform more accurate risk prediction. The purpose of this supplement is therefore to present associations between individual-level factors and COVID-19 death,stratified by age group.
