Dr. Robert Harrington (@HeartBobH), current Director of the DCRI and soon-to-be Chair of Medicine at Stanford, is a passionate advocate of the 3 Cs: Connectivity, Collaboration, and Communication. These principles and tools like social media have enormous potential to solve problems in health care if they are applied appropriately.  We need to do a better job of engaging patients in clinical research, disseminating evidence and guidelines,  and forming patient communities.  These are all possible with tools now available.  Recognizing the importance of communication and information dissemination, the ACC was very forward-thinking in having Dr. Harrington speak on the future of social media in medicine and clinical research.  In the spirit of his message, we have posted his talk here.  Pass it along!
