Slides from Daniel Ghinn's presentation at DIA (Drug Information Association) 4th Annual Clinical Forum, Lisbon, 13 October 2010. This session was part of the Medical Information & Communications track, and was aimed at orientating medical information professionals to the role of social media in healthcare engagement. It's a basic introduction to the changing roles of healthcare stakeholders and especially the 'e-Patient'; and includes examples of social media's role in healthcare engagement including a brand new case study of Pfizer's 'Can you feel my pain' strategy in Europe.
