I often get asked for real examples of what some people feel is theory only - basically, how are healthcare organisations using the variety fo social media possibilities to help creat/capture knowledge as well as transfer it / enable change. There are many of these - you can do your own searches and find things specific to you. I have listed below a few interesting ones:
a) Facebook: South Central Health Authority in England has an organisational profile on Facebook. Anyone can become a fan of the organisation (a novel thought in itself!) and then through Facebook - as a fan - I receive details of its public health campaigns (photos etc) and I have also been targetted through Facebook to answer a survey (which I then passed on to some of my Facebook friends).
b) at http://www.trainingpod.co.uk/ is an example of a hospital using audio podcasts to reduce training costs
c) Derby hospital in the England is handing out iPods preloaded with video instructions to their Radiology students as a means of enhancing the textbooks and the learning process http://news.bbc.co.uk/2/hi/science/nature/7780647.stm
d) A good example of a wiki is one supported by the National Library for Health (UK) which is focused on developing support materials for the commissioning process http://news.bbc.co.uk/2/hi/science/nature/7780647.stm ANyone can log in and add their twopennyworth and experience.
Social media is a practice not a theory...
