3. Social media and web based AE reporting in pharmacovigilance; is it the future? YES Should we apply the current laws and regulations to AEs in social media? NO Everything else to follow is an attempt to provide some perspectiveâŚ
4. âThe strange thing about living through a revolution is that it's very difficult to see what's going on... âŚOnly with the benefit of hindsight will we get a clear idea of what was going on. But the clarity that hindsight bestows is also misleading, because it understates how confusing things appeared to people at the time⌠ââŚSo it is with us now. We're living through a radical transformation of our communications environment. Since we don't have the benefit of hindsight, we don't really know where it's taking us. And one thing we've learned from the history of communications technology is that people tend to overestimate the short-term impact of new technologies â and to underestimate their long-term implications.â Naughton, John âThe internet: Everything you ever need to knowâ guardian.co.uk | The Observer Sunday 20 June 2010 Web 14Sep2010 http://www.guardian.co.uk/technology/2010/jun/20/internet-everything-need-to-know Naughton, John âThe internet: Everything you ever need to knowâ guardian.co.uk | The Observer Sunday 20 June 2010 Web 14Sep2010 http://www.guardian.co.uk/technology/2010/jun/20/internet-everything-need-to-know
5. âSocial Mediaâ Social media is media designed to be disseminated through social interaction, created using highly accessible and scalable publishing techniques. ...en.wikipedia.org/wiki/Social_media Any website or web service that utilizes a 'social' or 'Web 2.0' philosophy. This includes blogs, social networks, social news, wikis, etc.webtrends.about.com/od/web20/a/web20-glossary_2.htm Software tools that allow groups to generate content and engage in peer-to-peer conversations and exchange of content (examples are YouTube, Flickr, Facebook, MySpace etc)www.bottlepr.co.uk/glossary.html A million different definitions from a million different people. But over at Duct Tape Marketing they say â[s]ocial media is the use of technology combined with social interaction to create or co-create value.âwww.no2pen.com/blog/2010/01/social-media-dictionary-for-small-businesses/ media that is created to be shared freelyen.wiktionary.org/wiki/social_media The term social media describes media that is posed by the user and can take many different forms. Some types of social media are forums, message boards, blogs, wikis and podcasts. Social media applications include Google, Facebook and YouTube.www.searchenginepartner.com/SEO-glossary.html Social media is any form of online publication or presence that allows end users to engage in multi-directional conversations in or around the content on the website.www.onlinematters.com/glossary.htm Social media are primarily Internet- and mobile-based tools for sharing and discussing information among human beings.[1] The term most often refers to activities that integrate technology, telecommunications and social interaction, and the construction of words, pictures, videos and audio. ...www.creativemediafarm.com/information/glossary A category of sites that is based on user participation and user-generated content. They include social networking sites like LinkedIn or Facebook, social bookmarking sites like Del.icio.us, social news sites like Digg or Reddit, and other sites that are centered on user interaction.searchenginewatch.com/define Social media are works of user-created video, audio, text or multimedia that are published and shared in a social environment, such as a blog, wiki or video hosting site.www.capilanou.ca/help/login-page/active-cms/glossary.html
6. âSocial Mediaâ Web sites Social networking (e.g., Facebook, MySpace, LinkedIn) Wikis (Wikipedia) Blogs (web logs) Customer forums Micro Blogs (e.g., Twitter) Social bookmarking (e.g., digg) Location-based services (e.g., Foursquare) Virtual Worlds (e.g., Second Life) Patient Networking (e.g., PatientsLikeMe) by exampleâŚ
7. Is there a common characteristic to all this that will help us sort out how to view it vis a vis pharmacovigilance? I submit it is not some common characteristic in social media Rather, it is a characteristic that goes deeper (or wider or longer) than social media We can use this to anchor our discussion How to make sense of this..?

30. made possible by digitized healthcare data These new business models look like they can improve the way we do safety⌠they can improve public safety
34. The underlying problem is that weâre using rules and regulations and concepts which were developed when data was hard to find⌠âŚbut weâre trying to use them in a world that no longer matches the one in which they were developed hard to find no longer matches
35. "A design representation suitable to a world in which the scarce factor is information may be exactly the wrong one for a world in which the scarce factor is attention.â Herbert Simon The Sciences of the Artificial p.144
36. Weâve got a safety (and regulatory) system built on sparse, hard to get safety data.But weâre entering a world of abundant, easy to get safety data.
37. So what do we do? What we donât do is take each case as a unique âone-offâ situation⌠Should we monitor/collect from web sites? Should we monitor/collect from Facebook? Should we monitor/collect from Twitter? O, that way madness liesâŚ
40. Fallacy⌠Adverse event reports are not lilies in the field⌠there is not necessarily a finite number AE reports are the product of awareness and having a framework to observe them One of the determinants of the number of AE reports is how much news coverage the particular AE is getting So, the rate of AEs found by Nielson is not a rate set by nature, but a rate set by social interaction and awareness, and therefore subject to radical swings in frequency
41. A Twitter Daemon⌠Script written that would post from a Twitter account ⌠Script uses random names, dates, drugs, AEs, and always has the 4 elements For example⌠âMy uncle is 67 got terrible red rash from Xâ âMom took X lost feeling in her right armâ Could post one tweet per minute, 24 x 7, continuously
42. Iâm not saying we shouldnât collect AEs in social media⌠Iâm saying we need to call them something different than âseriousâ or ânonseriousâ AEs Maybe call them âPotential AE Lead Reportsâ ⌠This data clearly could be very valuable⌠âŚbut this is where our old concepts clash with the new world
43. Even better.. Designate the information from social media as a âpublic goodâ ⌠Allow searching and matching of potential adverse event âpointersâ by pharma, academics, others, with no attempt to apply todayâs regulations on reporting Reserve those regulations for specific programs a manufacturer runs on itâs drug ⌠This could address not only collection issues, but data privacy issues as well
46. 1946⌠Mr. Causby, of Greensboro, N.C., owned 2.8 acres consituting a chicken farm and residence near an airport outside of Greensboro, North Carolina. The flight path of planes was such that they may pass as low as 83 feet over his property. The airport was used by United States Military bombers, transports and fighters. They sometimes came close enough to the tops of the trees as to 'blow the old leaves off' the trees. "As many as six to ten of their chickens were killed in one day by flying into the walls from fright." They had to abandon their chicken business. They lost sleep and general health, becoming '...nervous and frightened...'

48. âestsolumejusestusque ad coelumâ âIt is ancient doctrine that at common law ownership of the land extended to the periphery of the universeâŚâ
49. ââŚBut that doctrine has no place in the modern world. The air is a public highway, as Congress has declared. Were that not true, every transcontinental flight would subject the operator to countless trespass suits. Common sense revolts at the idea. To recognize such private claims to the airspace would clog these highways, seriously interfere with their control and development in the public interest, and transfer into private ownership that to which only the public has a just claim."
50. ââŚThe farmer can't make money, e.g., by charging plane who travel in his airspace - but he is entitled to compensation for damages which occurred from the invasion of his airspace, because "...the land is appropriated as directly and completely as if it were used for the runways themselves."
52. Consider designating the social media information space a public good Formulate new rules to govern the use of this space Consider new classes of reports on drug safety Information lead Recurring syndrome Well-formed adverse event Serous adverse event Convene groups of informed individuals from pharma, government, academia, to start figuring out how to create the âCausby Solutionâ for drug safety in the world of digitized healthcare Some suggestions
