A deal between the National Health Service Somerset Foundation Trust and Sensyne Health, under which 1.1 million medical records will be sold, is raising privacy concerns, BBC News reports. The trust said only anonymized data will be shared with Sensyne Health, but privacy advocates claim information could still be used to identify patients. Sensyne Health CEO Paul Drayson said the agreement will improve patient care through research “by helping to grow our overall data set to over 5.6 million patients.”
