Visualizing Chronic Health (SXSW 2015)

  1. 1. VISUALIZING CHRONIC HEALTH CONDITIONS Brian Sherwell
  2. 2. SETTING THE STAGE
  3. 3. WHAT IS DATA VISUALIZATION? Data visualization is the creation and study of the visual representation of data. or “just draw it”
  4. 4. WHY VISUAL? Approximately 70% of the body’s sense receptors reside within the eyes. It is not just the amount of information collected, but also the subtlety of the information. HUE LENGTH ORIENTATION AREA LOCATION COLOR WIDTH SHAPE
  5. 5. WHAT IS DIABETES? a metabolic disease in which the body’s inability to produce any or enough insulin causes elevated levels of glucose in the blood. Type1vsType2vsGestational
  6. 6. DIABETES TREATMENT Blood Sugar Monitoring – Single Read & Continuous Treatment through oral mediations and Insulin 105
  7. 7. TYPICAL INSULIN DOSING ROUTINE 0 2 4 6 8 10 12 14 16 18 20 22 24 bolus dose basal dose
  8. 8. 18.8M children and adults in the United States have diabetes25.8M(8.3%) 81 83 85 87 89 91 93 95 97 99 01 03 05 07 09 11 2 4 6 8 10 12 14 16 18 20 1.9 MILLION NEW CASES diagnosed in people aged 20 years and older in 2010 WHY SHOULD WE CARE? diagnosed undiagnosed 7.0M prediabetes 79M Diabetes continues to be the leading cause of kidney failure, nontraumatic lower-extremity amputations, and blindness among adults, aged 20 – 74.7 years. – Center for Disease Control
  9. 9. WHY SHOULD WE CARE? $245 billion The total estimated cost of diagnosed diabetes in 2012 – American Diabetes Association $176 billion direct medical costs $69 billion reduced productivity
  10. 10. MY AH-HA MOMENT
  11. 11. APPALACHIAN TRAIL TREKKING 3 days 40.5 miles 122,713 steps 42.7lbs pack weight Calories burned: Insane!! Georgia
  12. 12. WHAT WERE THE EFFECTS? Calories consumed daily: 3500++ Average Blood Sugar Level: normally needed Basal Bolus 26 50 needed for this trip Basal Bolus 12 0-6 Amount of insulin per day 76
  13. 13. INSULIN USAGE VS ACTIVITY 0 10 20 30 40 50 60 70 80 10k 20k 30k 40k ACTIVITY (steps) My normal daily average
  14. 14. INSULIN EFFICIENCY VS ACTIVITY 0 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 10k 20k 30k 40k ACTIVITY (steps) My normal daily average
  15. 15. APPLICATION
  16. 16. COMPARING INSULIN TYPES rapid acting short acting intermediate acting long acting basal Starts 5–15 mins 15–30 mins 1–2 hrs 1–3 mins .75–1.5 hrs 2–3 hrs 4–8 hrs 6–12 hrs 3–5 hrs 4–6 hrs 12–18 hrs 20–24 hrs Peaks Lasts
  17. 17. VISUAL: COMPARING INSULIN TYPES 0 2 4 6 8 10 12 14 16 18 20 22 24 rapid acting short acting intermediate acting long acting basal
  18. 18. The glycemic index is a measure of how quickly blood glucose levels (i.e., blood sugar) rise after eating a particular type of food. The effects that different foods have on blood glucose levels vary considerably. GLYCEMIC INDEX Baguette 95 Pop tart 70 Yogurt 33
  19. 19. VISUAL: GLYCEMIC INDEX 0 1 2 3 4 Baguette Pop tart Yogurt
  20. 20. GLYCEMIC INDEX 0 1 2 3 4 Baguette
  21. 21. ALIGNMENT Rapid acting insulin (relative dose) 0 1 2 3 4 Baguette
  22. 22. 0 1 2 3 4 Pasta ALIGNMENT
  23. 23. 0 1 2 3 4 Pasta Rapid acting insulin (relative dose) ALIGNMENT
  24. 24. 0 1 2 3 4 Pasta Rapid acting insulin (relative dose) ALIGNMENT
  25. 25. WHAT ABOUT PREDICTION Power of data visualization is that it is a great way to show the future
  26. 26. CURRENT PREDICTIONBloodSugar
  27. 27. BETTER PREDICTIONActivityBloodSugar Alert! Low blood sugar predicted based on current activity Inputs activity insulin dosage food intake gsr blood pressure
  28. 28. CONCLUDING THOUGHT visualization is key to understanding complex health issues
