McKee warns that even subtle changes in the information being sent can lead to incorrect diagnosis or prescriptions, or even extended hospital stays.
Although a highly complex attack and therefore one not likely to be proliferated en masse, McKee’s presentation points to a larger trend in medicine; namely how technology is beginning to create new and complex risks.
