It's started! And right in our backyard! From 3 March the Heywood, Middleton and Rochdale Primary Care Trust is to run OOH GP services at the Heaton Park (Greater Manchester) branch of the supermarket Sainsburys. Two more are likely to open soon in the centre of Rochdale.
The Sainburys OOH GP service is being run by a private company aptly named Doctors in Store. And they'll have access to your medical records via computer!
