  11. surgeons were given detailed diagnoses & asked if patients should get surgery … half said yes … the other half said no … when asked again two years later, 40% of the docs gave a different answer Source: http://jama.jamanetwork.com/article.aspx?articleid=380215

  12. four cardiologists were asked to diagnose stenosis in patients using high-quality angiograms … … they disagreed 60% of the time …and disagreed with themselves (on re-reads) 8-37% of the time

  13. fifty-eight experts’ estimates of the chance of an outcome of an important procedure 0% 0.2% 0.5% 1% 1% 1% 1.5% 1.5% 2% 3% 3% 4% 5% 5% 5% 5% 5% 5% 5% 6% 6% 6% 8% 10% 10% 10% 10% 13% 13% 15% 15% 18% 20% 20% 20% 25% 25% 25% 30% 30% 40% 50% 50% 50% 62% 70% 73% 75 75% 75% 75% 80% 80% 80% 80% 80% 80% 100% what does a consensus of a group whose perceptions might vary from 0% to 100% even mean?

  15. conventional wisdom and the “tradition of medicine” • should fever be reduced in critically ill patients? • “there were seven deaths in people getting standard treatment and only one in those allowed to have fever” • “the team felt compelled to call a halt, feeling it would be unethical to allow any more patients to get standard treatment” Source: http://www.newscientist.com/article/mg20727711.400-fever-friend-or-foe.html

  16. nearly half of all american adults have difficulty understanding and acting upon health information institute of medicine of the national academies, 2004 http://www.nap.edu/openbook.php?record_id=10883&page=1

  17. there is good reason to challenge the assumption that every individual practitioner's decision is necessarily correct eddy, et al., jama, 1990

  18. for most study designs and settings,it is more likely for a research claim to be false than true ioannidis, plos med, 2005

  19. inescapable conflicts of interest… …most physicians are motivated to deliver quality care… …but the typical physician response also includes a desire to protect high salaries… http://online.wsj.com/article/SB10001424052702303983904579093252573814132.html

  20. entrepreneurs will ask the naïve questions that uncover hidden assumptions… …and move us to the grey zone of “speculations”

  22. 80% of what MDs do can be replaced (with better care than the average MD)… …but not every MD function will be replaced

  23. the “human” element of care can be provided by the most “humane” humans (and MDs can be humane)

  24. machines are better at integrative medicine… …across “all symptoms”, demeanor, patient history, phone activity, 1000s of data points, genomics, population management guidelines, … …and machines won’t have to win every time… …they’ll just be better overall

  25. Lifecom CHAMP in acute care I …distributed care with medical assistants were 91% accurate without labs, imaging, or exams II …“safe triage” with 75% physician bypass rate for acute care encounters

  26. isabel II matched expert diagnoses 91-95% of the time

  27. dr. algorithm v0

  28. the transition will start with “toddler MDs” and digital first-aid kits

  29. Cellscope: ENT+ derm images… Eyenetra: auto-optometrist Alivecor: frequent EKG+ analysis Quanttus: physiological metrics (HR, BP, SV, CO, RR, T, …) Ginger.io: mental health Adamant: breath analysis Kyron: practice based evidence Medgle: graph of medicine Healthtap, Crowdmed: crowdsourced answers Jawbone, Misfit: wellness wearables

  30. don’t wait days to take your daughter to the hospital… …check her ear infection as soon as it hurts CellScope *a khosla ventures investment

  31. don’t go to the hospital and get connected to a bunch of electrodes… …take your own ecg for less than a buck… …and know you have heart disease before you have an attack! AliveCor *a khosla ventures investment

  32. don’t go to the optometrist… …get measured for glasses at home EyeNetra *a khosla ventures investment

  33. don’t guess what’s going on inside your body… …get vital intelligence Quanttus *a khosla ventures investment

  34. don’t wait for an asthma attack… …know when it’s coming NOx: 40ppm Adamant Technologies Adamant *a khosla ventures investment

  36. graph the world of medicine… …and see where you fit MEDgle *a khosla ventures investment

  37. evidence-based medicine isn’t enough… …think practice-based evidence … use data-mining to learn ethnicity-specific drug interactions (e.g. statins work differently in Indians) Kyron *a khosla ventures investment

  38. thousands of physicians… …no waiting room HealthTap *a khosla ventures investment

  39. ...and your innovation here (call us)

  40. healthcare service stations & digital first aid kits

  41. keep people out of the doctor’s office… …with point innovations in cardiology, dermatology, optometry, psychiatry, internal medicine, …

  42. innocuous point innovations… …will evolve into a wave and explode into a tsunami

  43. dr. algorithm v0 v1 – 2015 v2 – 2017 v3 – 2019 v4 – 2021 v5 – 2023 v6 – 2025 …

  44. we’ll start with clumsy point innovations like alivecor, cellscope, adamant, ginger.io, neurotrek, consumer physics, jawbone, misfit, … …“insighted” by machine learning… …leading us to discover things we never knew were right in front of us

  45. the best MDs will train systems over 10 years… …systems will symbiotically provide “bionic assist” and “AMPLIFY” MDs

  46. dr. house+++ will be the trainer for dr. algorithm …no manners required! …but manners learned!

  47. findings thanks to data using statins for in-hospital stroke patients reduced the death rate by 40%! kaiserpermanente

  48. the practice of medicine the science of medicine

  49. I will be wrong on the specifics but directionally right

  50. the shift to “computerization” has already happened in other areas… …airline pilots, stock trading, car driving
