Social media enables an immediate exchange of information and ideas around shared areas of interest, and has fostered communication and collaboration among a global network of healthcare researchers, clinicians, patients, and learners. Social Media in Medicine reviews a range of topics, from research ethics to medical education, and includes personal reflections by clinicians and learners, representing diverse opinions about the role of social media in medicine. This book was originally published as a special issue of the International Review of Psychiatry.
