1 Big Data: How Can it Guide Practice and Health Care Reform Eric D. Peterson, MD,MPH Executive Director, Duke Clinical Research Institute April 2015

2 The Best of Times The Worst of Times Science and IT are advancing at incredible speeds, but: Yet Poor transition of bench to bedside Lack of evidence for much of what is done in medicine Slow adoption of useful therapies Medical costs rising exponentially All Rights Reserved, Duke Medicine 2007 sb/strategy & Innovation Group 2

8 How Big is Big Data Just in 2010, 4 exabytes (4 x ) of unique data was generated, which was more than in the preceding 5,000 years altogether "Every 2 days we now create as much information as we did from the dawn of civilization up to 2003 (Eric Schmidt, Google CEO) The amount of new data is now doubling every 13 months -and will soon double every 12 hours according to IBM For college students in technical degree, half of what they learn in their first year of study will be outdated by their third year Brett King, Huff Post Tech; June 4, 2014 [ Ray Kurzweil, The Law of Accelerating Returns; March 7, 2001 [ David Russell Schilling, Knowledge Doubling Every 12 Months, Soon to be Every 12 Hours; industry tap into news, April 19th, 2013 [ All Rights Reserved, Duke Medicine 2007 sb/strategy & Innovation Group 8

9 Data Driven Medicine: Not a New Concept Collecting Data, Asking Questions, & Translating it to Practice Chronic diseases can be studied, but not by the methods of the past. If one wishes to create useful data computer technology must be exploited. Eugene Stead, MD 1969 Led to the concept of computerized textbook of medicine Formed foundation of the Duke Databank for CV Diseases Spurred a generation of clinical and quantitative researchers All Rights Reserved, Duke Medicine 2007 sb/strategy & Innovation Group 9

10 Value of Aggregated Medical Data Database Size Examples Clinician s Experience s Osler, Harvey Single Center Database 1,000-10,000 s Duke, Emory Epidemiological Cohort 10,000 s Framingham, MESA National Registries 1,000,000 s AHA, ACC, STS EHR / patient-powered Registries 10,000,000 s PCORnet, Health eheart registry All Rights Reserved, Duke Medicine 2007

16 IT and Healthcare Promise and Challenges DATA INTEGRATION ANALYTICS ACTION 90% of world s data has been created in the last 2 years. But 80% of that data is unstructured and stored in separate systems. Big data analytics is coming to medicine: Google, IBM Watson Will need to integrate these data into practice.

Below that in purple, another indicator of economic status. The bottom layer maps the county boundary and streets. Vertical green spines longitude ad lattitude coordinates of where diabetes patients live and locations of key social or commercial institutions, that can be used to link all of these disparate data sets together based on shared geography.

34 Conclusion: The Future of Big Data, Practice and Policy In the past, clinicians were limited by existing technologies and therapeutic options. Today, our clinical, research & IT capacities can drive amazing progress. However, progress will not occur without the development of novel IT and informatics, more efficient research, and more rapid and effective learning health systems We need to harness the emerging data deluge to create new knowledge and translate this into better care All Rights Reserved, Duke Medicine 2007 sb/strategy & Innovation Group 34
