The Construction of Expertise in the Age of the Internet: Psychotropic Drug Knowledge in Online Consumer Accounts Shannon Hughes, MSW, Ph.D. Candidate Florida International University, Miami, FL Non-presenting author: David Cohen, Ph.D. Medicine 2.0 , Toronto, Ontario September 4-5, 2008
Speech of Drug User is Fundamental
Psychoactive agents with overall effects
No physiological markers for diagnosis
For psychotropic drugs, there is “difficulty in applying valid and sensitive measures of therapeutic effect”
Brunton, Lazo, & Parker (2006). Goodman & Gilman’s The Pharmacological Basis of Therapeutics, 11 th ed.
Randomized Controlled Trial (RCT) Mutes Users’ Voices
Investigator-rated measures
Narrowly defined outcomes
Few opportunities for unstructured speech
Limited investigator/participant interaction
Methodological problems, including lack of methods for assessing adverse events
Pharma Funds 70% of Research
42 published head-to-head antipsychotic trials:
33 (78.6%) were funded by a pharma company
90% reported outcomes favoring the sponsor’s drug
Analysis of 12 antidepressants :
94% of published articles reported positive outcomes,
51% of outcomes were positive according to FDA reviews
Hundreds and thousands of unmediated, direct accounts
Brain shivers: Example of adverse event “discovered” online
Potential of consumer sites is virtually unexplored
Typology of Sites
Expert-run
Expert health: www.webmd.com
Consumer-centric : www.revolutionhealth.com
Consumer-run
High structure: www.askaptient.com
Moderate structure: www.crazymeds.us
Little structure: www.theicarusproject.net
Where Can You Get The Full Drug Story?
Expert-run
Unitary discourse
Accept mainstream/official accounts
Consumer-run
Heterogeneous discourses/perspectives
Accept/reject mainstream/official accounts
Are Consumer Drug Accounts Credible?
Are persons with vested interests contributing drug reviews?
Pharma literature on Direct-to-Consumer Advertising suggests an interest in online “patient communities”
- O'Neill, 2007
Head of Operations of a consumer-centric site:
“… pharma personnel are ‘discouraged’ from visiting these websites because if they see an unreported SAE, they would be bound to report it to the FDA”
“ What happens at the rep level, however, is tough to monitor. That said, with 250,000+ individuals enrolled in [our website], its hard to think that ‘sales representatives going against FDA/company policies’ can skew the data significantly”
Owner/moderator of a consumer-run forum:
“ We had someone from Cephalon come by. The person was easy to spot. Again I'm fine with it. It's just like science. They have to defend their positions and we have to defend ours”
“ Given that they have set up their own sites I seriously doubt if they are going to bother with peer-to-peer sites / user generated media …”
Gauging Pharma Activity using Wikiscanner
Between 2002-2007, over 34.5 million anonymous Wikipedia edits ( ~ 18-21% of all edits)
187,529 different orgs made at least 1 edit
7% of a database of over 2.6 million org IP addresses
Astra Zeneca edit deleting a sentence about suicidal thinking/behavior
Pharma Wikipedia Edits, 2002-2007 Omeprazole : Deleted sentence about heavy marketing of Nexium in the face of generic competition; Added summaries of several studies where Nexium outperforms Prilosec Drotrecogin alfa : Deleted word “deceptive” before “marketing campaign” ; Deleted 6 contraindications GlaxoSmithKline : Added paragraph about “Good Works” of company Total Edits Edits related to meds/pharma Example edited entries Astra Zeneca 949 23 (2.4%) quetiapine ; omeprazole Eli Lilly 832 38 (4.6%) drotrecogin alfa; Talk:fluoxetine GSK 1,148 31 (2.7%) GlaxoSmithKline
Authenticity is unresolved and evolving
Pharma Wikipedia edits were relatively infrequent and innocuous
As consumer sites increase in importance, stakes for pharma to shape perception rise
Research, Clinical, Consumer Implications
Post-marketing surveillance using consumer sites
Content of expert/consumer sources should be compared and related to informational needs of treatment decision-makers
Allow space for “consumer-run” sites in order to maintain heterogeneity of perspectives and discourses
