'Our health data is about to flow more freely, like it or not': big tech's plans for the NHS

Last December, I had an abortion. Most unwanted pregnancies set a panic-timer ticking, but I was almost counting down the seconds until I had to catch a flight from London, where I live, to Texas, where I grew up, and where the provision of abortion care was recently made a felony. You bleed for a while after most abortions, and I was still bleeding when I boarded the plane home for Christmas. Going to Texas so soon after the procedure made me consider where the record of my abortion – my health data – would end up. When I phoned an abortion clinic in late November to book an appointment, one of the first questions staff asked was: "May we share a record of your treatment with your GP?" It's not just that a complete health record helps my GP treat me. My Texan parents, both scientists, taught me that sharing information with organisations like the NHS can help it plan services and research ways to improve care. I've joined clinical studies in the past. But I also help run a legal campaign group, Foxglove, that takes action against the government and tech companies when they infringe people's rights. In a series of cases about NHS data since the start of the pandemic, we have defended people's right to a say about who sees their medical information. This work has exposed me to worrying details about how our medical data can be used, including the Home Office practice of tracking migrants using their health records. For decades the government has required GPs to store patients' records in a standardised way: as well as longhand notes, every interaction with a GP is saved on a computer database in a simple, consistent code.
