This finding raises important questions about how Long COVID is diagnosed, recorded, and managed in the NHS. Good data on Long COVID will be crucial for research into the prevalence of Long COVID, its causes and consequences, and to plan services effectively. It was built specifically to address privacy concerns around access to patient records for research. OpenSAFELY is the first service ever to run research analyses across the full GP records of almost the whole population. The research was jointly funded by UK Research and Innovation, the National Institute for Health Research, Asthma UK-BLF and the National Core Studies programme.
