British hospitals are running out of surgeons as they try to prepare for new rules that will cut doctors' working hours, leading medics warn. The Association of Surgeons in Training surveyed 1,096 trainee surgeons, and 90% said they were working more than the maximum of 58 hours a week. Under the European Working Time Directive, this will be cut to 48 hours beginning in August. The Royal College of Surgeons warns that staff levels may be cut too much.
