The U.K. National Health Service postponed its patient data sharing program indefinitely due to a wave of patient opt outs, the Guardian reports. The sharing scheme was initially postponed from July to September and now has no set launch date. While the total number of opt outs to this point is unknown, 1,275,153 individuals opted out in June alone. Phil Booth, coordinator of medConfidential, acknowledged there are "legitimate, ethical, research and planning uses that can be made" for the program, but "it just has to be done right."
