Intravenous news: The BBC report “Patients should double-check that medical staff have got the right person before they willingly receive blood, says a new campaign. NHS Blood and Transplant says although rare, errors do happen, and most are due to mistaken identity. In 2012, out of three million blood transfusions in England and Wales there were nearly 250 incidents where the wrong blood was given. The Department of Health says mistakes such as these should never happen. Misidentification of patients and transfusing incompatible blood are on their list of ‘never events’ – situations they say should be entirely avoidable.
