A malpractice ruling from the Minnesota Supreme Court is causing angst in the state’s medical and legal communities. The high court recently ruled a doctor can be sued for malpractice even if he or she is not directly treating a patient. The decision involves an Iron case in which a hospital doctor allegedly refused to admit a patient who was being treated by a nurse practitioner. The physician-based his decision on a 10-minute telephone call. The patient died several days later.
