Episte…what?
EPISTEMONIKOS(ΕΠΙΣΤΗΜΟΝΙΚΟΣ )
What is worth knowing
Who we areEpistemonikos is a nonprofit organization based in Santiago, Chile
Our mission is “to bring high quality information closer to health decision making”
The problem: information overload
New oral anticoagulants in atrial fibrillation
The problem is you dont know the secrets of PubMed
("Atrial Fibrillation"[Mesh] OR "Atrial Flutter"[Mesh] OR ((atrial OR auricular) AND (fibrillation* OR flutter*)) OR AF[Text Word]) AND ("Factor Xa/antagonists AND inhibitors"[Mesh] OR ((factor xa OR factors 10a OR fXa OR autoprothrombin c OR thrombokinase) AND inhibit[Text Word]) OR (activated AND (factor x OR factors 10) AND inhibitor*) OR xabans[Text Word] OR (antistasin OR apixaban OR betrixaban OR du 176b OR eribaxaban OR fondaparinux OR idraparinux OR otamixaban OR razaxaban OR rivaroxaban OR aygin OR ym 150 OR ym150 OR LY517717 OR darexaban OR edoxaban OR SSR126517E) OR ((dabigatran OR BIBR1048) OR ximelagatran OR AZD0837))
Oooops…..but you can search
“systematic reviews” [best evidence]
Much better, ah?Yoy can start reading
…see ya!
8 systematic reviews for my question
Wake up!!! You have to read them, compare which
studies they include….and beg they are well conducted, say the same thing and address the same
studies. Out of bed, sleepyhead!!!
The challenge: to separate the wheat from the chaff
23,000,000 records only in PubMed
• 0,25% are systematic reviews
Our goal
TO AGGREGATE ALL THE RELEVANT HEALTH EVIDENCE (FOR DECISION-MAKING) INTO A SINGLE DATABASE.

What evidence?
Systematic reviewsOverviews of reviewsHigh-quality structured summariesPrimary studies included in systematic reviews
Systematic reviews (SR) at the centre
• The average SR takes about 1-year of work
• We rescue that effort by storing identified studies
From: http://www.navigatingeffectivetreatments.org.au/understanding_systematic_reviews.html The Centre for Health Communication and Participation with support from the Australasian Cochrane Centre
All that effort into a single database
If the reviewers found it, we’ve got it
Unpublished!!!
Where do we search? 19 databases
How do we feed Epistemonikos?
• Combination of machine technology and human collaboration
Automatic search and upload
Selection of actual systematic reviews by a network of collaborators
Extraction of the studies included in the systematic review

How Epistemonikos compares to existing resources?
Let’ see an example
New oral anticoagulants in atrial fibrillation
All the evidence (systematic reviews and studies) for our question *The matrix of evidence is expected to be released at the end of this year
Conclusions
• One-stop shop for evidence• Multilingual database• User friendly• Relation between articles answering a similar
question• Visualisation of ‘all the evidence’ for a specific
question
