OpenSAFELY

OpenSAFELY is an interface to NHS patient records which enables statistical analysis of them by medical researchers. Initially, it has been used to make an analysis of the risk factors associated with deaths from COVID-19 in hospital in the UK.[1] This is significant because the dataset is especially large – 20 billion rows of data for about 24 million patients.[2]

This article is about the medical records statistical platform. For the machinery communication protocol, see OpenSAFETY.

The platform interfaces with a secure database of pseudonymized primary care records, and only aggregated results are viewable by researchers. This allows researchers to access a large dataset necessary for identifying potential risk factors without the risks of exposing personal patient information.[3]
