Presentation Looks into the Future of Oncology Nursing in a Digital Age

  1. 1. The Future of Oncology in a Digital Age Kent Bottles, MD Chief Medical Officer, PYA Analytics Thomas Jefferson University School of Population Health April 1, 2014 Scofield Advanced Oncology Nursing Conference Coralville, Iowa
  2. 2. The End of Illness David Agus, New York: Free Press, 2011 • “Take a moment to imagine what it would be like to live robustly to a ripe old age of one hundred or more. Then, as if your master switch clicked off, your body just goes kaput. You die peacefully in your sleep after your last dance that evening. You don’t die of any particular illness, and you haven’t gradually been wasting away under the spell of some awful, enfeebling disease that began years or decades earlier.”
  3. 3. Jeff Goldsmith on Digital Future • “David never spent a day in the hospital, and had one home and two office visits with his physicians during the course of treatment, which consisted in its entirety of six weeks’ worth of home infusion therapy.
  4. 4. Jeff Goldsmith on Digital Future • The bill for all these services was created, evaluated, and paid electronically, with David’s nominal portion of the cost billed to his Visa card, per agreement with his health plan. He never saw a paper bill, though he could view the billing process in real time on his health plan’s website.”
  5. 5. Traditional Medicine • Diagnose and treat • Health is defined as absence of disease • Patient story is subjective and untrustworthy • Lab results are objective and true • Pathologists are the most important doctors • Clinicians are paralyzed until lab provides dx
  6. 6. Traditional Medicine • Biomedical model reduces every illness to a biological mechanism of cause and effect • Attention on acute episodic illness • Generalists replaced by specialists • Focus on individuals • Cure as uncompromised goal • Focus on disease • Antibiotics & infectious disease
  7. 7. Digital Medicine of Present & Future • Predict and Prevent • Health is a state of complete physical, mental, and social well-being and not merely absence of disease • Patient story is essential for development of personal metrics which will be unique to each individual • Pathologist sadly becomes less important
  8. 8. Systems Biology Yields New Therapies http://www.nytimes.com/2012/06/03/business/geneticists-research-finds-his-own- diabetes.html?_r=1&pagewanted=print • Michael Snyder sequenced his genome that showed he was at high risk for Type 2 Diabetes • Blood tests every 2 months of 40,000 molecules • After 7 months showed he had developed DM • Early detection, early treatment • “This study is a landmark for personalized medicine.” Eric Topol
  9. 9. Digital Medicine • Digitizing a human being – Genome – Remotely, continuously monitor vital signs, mood, activity – Image any part of body, 3D reconstruction, print an organ – Readily available on your smartphone, integrated with traditional medical record, constantly updated
  10. 10. Digital Medicine Convergence • Genomics • Wireless sensors • Imaging • Information Systems • Social networks • Ubiquity of smartphones • Unlimited computing power via cloud server farms
  11. 11. Rules vs. Complex Tasks • Tasks that require application of rules by use of algorithms • Information processing tasks that cannot be boiled down to rules – Pattern recognition – Complex communication • The New Division of Labor by Frank Levy and Richard Murnane, 2004
  12. 12. The Digital Age • Exponential • Digital • Combinatorial
  13. 13. The Digital Age • Exponential – “The greatest shortcoming of the human race is our inability to understand the exponential function.” Albert A. Bartlett – Chess invented in sixth century CE, Gupta Empire – “Place one single grain of rice on first square of the board, two on the second, four on the third, and so on.” – 18 quintillion grains of rice; taller than Mt. Everest – Numbers so big they are inconceivable
  14. 14. The Digital Age • Exponential – ASCI Red fastest computer in world in 1996 ($55 million and 1600 square feet of floor space) – 1.8 teraflops of computer speed – Sony PlayStation 3 in 2005 ($500 and less than a tenth of a square meter): Sold 64 million units – 1.8 teraflops of speed
  15. 15. The Digital Age • Exponential – Second machine age – Second half of the chess board – “into a time when what’s come before is no longer a particularly reliable guide to what will happen next”
  16. 16. The Digital Age • Digitalization of everything – Waze tells you what route is best right now due to network effort – Information is non-rival and close to zero marginal cost of reproduction – Products are free, perfect, and instant – “Information is costly to produce but cheap to reproduce.” Carl Shapiro and Hal Varian – “I keep saying that the sexy job in the next ten years will be statisticians. And I’m not kidding.”
  17. 17. The Digital Age • Digitalization of everything – Waze tells you what route is best right now due to network effort – Information is non-rival and close to zero marginal cost of reproduction – Products are free, perfect, and instant – “Information is costly to produce but cheap to reproduce” Carl Shapiro and Hal Varian – “I keep saying that the sexy job in the next ten years will be statisticians. And I’m not kidding.”
  18. 18. Digital Age • Combinatorial – Combining things that already exist – Kary Mullis 1993 Nobel Prize in Chemistry PCR – “I thought it had to be an illusion…It was too easy…There was not a single unknown in the scheme. Every step involved had been done already.” – Crowdscourcing with Innocentive or Kaggle – Waze
  19. 19. The Digital Age • The emergence of AI and connection of most of the people on globe via common digital network • Computers can now demonstrate broad abilities in pattern recognition and complex communication
  20. 20. Moravec’s Paradox • “It is comparatively easy to make computers exhibit adult-level performance on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a one-year old when it comes to perception and mobility.” • “Contrary to traditional assumptions, high-level reasoning requires very little computation, but low-level sensorimotor skills require enormous computational resources.”
  21. 21. The Digital Age • Watson, Jeopardy, and Medicine • Human doctor would need to read 160 hours every week to keep up with relevant new literature • Freestyle chess tournaments: teams have any combination of human and digital players • Weak human + machine + better process superior to strong computer or strong human + machine + inferior process
  22. 22. Something Computers Cannot Do • Ideation • Coming up with new good ideas or concepts • Partnership between Dr. Watson and a human doctor will be far more creative and robust than either of them working alone • “You’ll be paid in the future based on how well you work with robots.” Kevin Kelly
  23. 23. Something Computers Cannot Do • Jeffrey Dyer and Hal Gregersen interviewed 500 prominent innovators • Disproportionate number went to Montessori • Not following rules • Self motivation • Questioning • Doing things a bit differently
  24. 24. Big Data Viktor Mayer-Schonberger & Kenneth Cukier, 2013 • Big data refers to things one can do at a large scale that cannot be done at a smaller one, to extract new insights or create new forms of value, in ways that change markets, organizations, the relationship between citizens and governments. • Causality is replaced by correlation • Not knowing why but only what
  25. 25. The Amount of Data Available is Truly Big • The International Data Corporation reported that the amount of digital data exceeded 1 zetabyte in 2010. • In 2011 this number was almost 2 zetabytes. • Google’s Eric Schmidt claims that every two days we create as much information as we did from the dawn of civilization up until the year 2003.
  26. 26. Sizing Up Big Data Steve Lohr, NY Times, June 20, 2013 • Bundle of technologies – Web pages, browsing habits, sensor signals, social media, GPS location data, genomic information, surveillance videos – Advances in data storage and processing – Machine learning/AI software to find actionable correlations from the big data
  27. 27. Sizing Up Big Data Steve Lohr, NY Times, June 20, 2013 • Philosophy about how decisions should be made – Decisions based on data and analysis – Less based on experience and gut intuition – Eliminates anchoring bias and confirmation bias • Revolution in measurement – Digital equivalent of the telescope – Digital equivalent of the microscope

  36. 36. Digital Medicine of Present & Future • Agus consulted on treatment of Steve Jobs • Jobs had both his cancer and normal cells sequenced for molecular targeted therapy • Oncologists customized his chemotherapy to target specific defective molecular pathways in his tumor • Treatment changed when tumor mutated during therapy
  37. 37. Digital Medicine of Present & Future • One of Steve Jobs’ doctors said there was hope that his cancer would soon be considered a manageable chronic disease, which could be kept at bay until he died of something else. • “I’m either going to be one of the first to be able to outrun a cancer like this, or I’m going to be one of the last to die from it. Either among the first to make it to shore, or the last to get dumped.”

The Hidden Biases of Big Data http://blogs.hbr.org/cs/2013/04/the_hidden_biases_in_big_data.html • Big Data vs. Data with Depth • “With enough data, the numbers speak for themselves.” Chris Anderson • Can numbers actually speak for themselves? Sadly, they can't. Data and data sets are not objective; they are creations of human design. We give numbers their voice, draw inferences from them, and define their meaning through our interpretations. • Hidden biases in both the collection and analysis stages

Vinod Khosla (Sun Microsystems) http://techcrunch.com/2012/01/10/doctors-or-algorithms/ • Being part of the healthcare system is a disadvantage to disrupting the status quo • Machine learning system will be cheaper, more accurate, and more objective than physicians • Machine expertise would need to be in the 80th percentile of human physician expertise
  65. 65. Vinod Khosla (Sun Microsystems) http://techcrunch.com/2012/01/10/doctors-or-algorithms/ • Do we need doctors or algorithms • “Health is like witchcraft and just based on tradition” • 80% of physicians will be replaced by machines • 80% of doctors are below the top 20% • We will not need average doctors. • Still need “doctors like Gregory House who solve biomedical puzzles beyond our best input ability”
  66. 66. Will Robots Steal Your Job? http://www.slate.com/articles/technology/robot_invasion/2011/09/will_robots_steal_your_job_3.single.ht ml • “At this moment, there's someone training for your job. He may not be as smart as you are—in fact, he could be quite stupid—but what he lacks in intelligence he makes up for in drive, reliability, consistency, and price. He's willing to work for longer hours, and he's capable of doing better work, at a much lower wage. He doesn't ask for health or retirement benefits, he doesn't take sick days, and he doesn't goof off when he's on the clock.What's more, he keeps getting better at his job.”

We’re there because we’re sick…, and we’re hoping this arrogant, hurried, credentialed genius can tell us what’s wrong. We go to doctors not because they’re great empaths, but because we’re hoping medical school has made them into the closest thing the human race has developed into robots.”
