HISTORIC MOMENT
Today at 14:40 Dr Mark Russell from KCL pressed the button to execute the first ever job on the new OpenSAFELY service. Until today, OpenSAFELY was COVID only. Now we are open to critical analyses that improve all patient care, on GP records, securely, at scale.
PICS!
THREAD!
Just went to The Music Box on Cowley Rd to get my guitar fixed. I bought it in 1990 aged 16 for £85, from him. Now he's the only instrument shop left in Oxford. No smiling photos because (a) I'm not like that (b) as you'd hope from a great guitar shop he's appalled at the prospect of more customers.
OpenSAFELY opened for non-COVID work in February. We got 100 applications in two months. We hope we can open to applications in England again very soon!
We're also building OpenSAFELY tools in other countries.

Because of that, you can watch every line of code from Mark Russell as it executes in the system, live. He pressed the button with us all on a call (cheers! tearfulness!) at 1440. As of 1536, the dataset for incidence analyses is done, 3 more are running. Go!

How you pop to the shops, if it's minus 64° Celsius in your town. This is what I want from the internet, and culture: other people's fascinating lives. Not lies about crime in London invented by boring racists.

My old friend Patrick Mthews @HoxtonBeach slogged for years to build up a few small struggling cafes in London parks. Now they're a success, so the parks are rewarding him by giving the cafes to someone who offered them more money

PING!
We've won the Queen Elizabeth Prize for Education with our work on OpenSAFELY, inventing new methods that let researchers analyse NHS GP data while protecting everyone's privacy, and with complete transparency, in a hugely productive platform!
