ORLANDO, Fla.The social media train has left the station, according to Safwan S. Halabi, MD, of Henry Ford Health System in Detroit. Practices need to get onboard, he said. Otherwise, physicians and medical practices will be defined, perhaps negatively, by outsiders. During a June 7 session at the annual meeting of the Society for Imaging Informatics in Medicine (SIIM), Halabi urged attendees to understand and control social media.
