March 12, 2007 Although cellular telephone use has been prohibited in hospitals because of concerns of interference with medical devices, a new study by Mayo Clinic researchers shows that calls made on cellular phones have no negative impact on hospital medical devices, dispelling the long-held notion that they are unsafe to use in health care facilities. Three hundred tests were performed over a five-month period in 2006 using two cellular phones, which used different technologies from different carriers and 192 medical devices. Not a single problem was found. The study's authors say the findings should prompt hospitals to alter or abandon their bans on cell phone use.
