Challenge of Predicting Anything Human 9


Слайд 9

What Should We Expect In Healthcare? Machines are predictable; humans aren’t 10 “People are influenced by their environment in innumerable ways. Trying to understand what people will do next, assumes that all the influential variables can be known and measured accurately. People's environments change even more quickly than they themselves do. Everything from the weather to their relationship with their mother can change the way people think and act. All of those variables are unpredictable. How they will impact a person is even less predictable. If put in the exact same situation tomorrow, they may make a completely different decision. This means that a statistical prediction is only valid in sterile laboratory conditions, which suddenly isn't as useful as it seemed before.” Gary King, Harvard University and the Director of the Institute for Quantitative Social Science

Concepts & Principles of Predictive Analytics 12


Слайд 12

Semantics, Ssschmantics Predictive Analytics and Predictive Models: These terms have their origins in statisticians; e.g., understanding real-world phenomena such as healthcare, retail sales, customer relationship management, voting preferences, etc. Machine Learning Algorithms: This term has its origins in computer scientists; e.g., natural language processing, speech recognition, image recognition, adaptive control systems in manufacturing, robots, satellites, automobiles and aircraft, etc. 13 As it turns out, the latter can be applied to the former, so the two schools of thought are now generally interchangeable. Don’t let vendors fool you into thinking that “machine learning” is more sophisticated or better than predictive modeling.

Слайд 15

The Basic Process of Predictive Analytics 16


Слайд 16

A Big & Common Mistake: Over Fitting 17 You train the model to be very specific on a given data set, but the model cannot adapt to a new, unknown data set


Слайд 17

Specificity vs. Sensitivity: Trading One For Another Specificity: The true negative rate. For example, the percentage of diabetic patients identified who will not have a myocardial infarction Sensitivity: The true positive rate. For example, the percentage of diabetic patients that will have a myocardial infarction


Слайд 18

Receiver Operating Characteristic (ROC) Plot 19 Tuning radar receivers in WWII Maximum radar receiver sensitivity led to many false positives… too many alarms Lower radar receiver sensitivity led to many false negatives… missed threats Same challenge in airport security screening systems and spam filters Concept has been applied heavily in diagnostic medicine True Positive Rate vs. False Positive Rate


Слайд 19

Data Volume vs. Predictive Model “But invariably, simple models and a lot of data trump more elaborate models based on less data.” “The Unreasonable Effectiveness of Data”, March 2009, IEEE Computer Society; Alon Halevy, Peter Norvig, and Fernando Pereira, Google

Predictive Precision vs. Data Content 23


Слайд 23

Thank you for the graphs, PreSonus Healthcare and patients are continuous flow, analog process and beings But, if we sample that analog process enough, we can approximately recreate it with digital data 24 Remember Your Calculus Digital Sampling Theory?


Слайд 24

We are asking physicians and nurses to act as our “digital samplers”… and that’s not going to work 25

“Mr. Sanders, while your 9-year tenure as an inmate has been stellar, our analytics models predict that you are 87% likely to become a repeat offender if you are granted parole. Therefore, your parole is denied.” - 2014, 80% of parole boards now use predictive analytics for case management* * The Economist, “Big data can help states decide whom to release from prison” April 19, 2014 27

Common applications being marketed today Identifying preventable re-admissions: COPD, MI/CHF, Pneumonia, et al Sepsis Risk of decubitus ulcers LOS predictions in hospital and ICU Cost-per-patient per inpatient stay Cost-per-patient per year by disease and comorbidity Risk of ICU mortality Risk of ICU admission Appropriateness of C-section Emerging: Genomic phenotyping 34

Слайд 35

Not all patients can functionally participate in a protocol At Northwestern (2007-2009), we found that 30% of patients fell into one or more of these categories: Cognitive inability Economic inability Physical inability Geographic inability Religious beliefs Contraindications to the protocol Voluntarily non-compliant Socioeconomic Data Matters 36


Слайд 36

The key to predictive analytics in the future of health care will be the ability to answer this two-part question: What’s the probability of influencing this patient’s behavior towards our desired outcome and how much effort (cost) will be required for that influence? Return on Engagement (ROE)

Wrapping Up 50


Слайд 50

Key Questions To Ask Of Vendors and Your Analytics Teams 51 What is your formal training, education, and practical experience in this field? What are the input variables to the model? What model and/or algorithms are you using and why? How are you going to train the model? Are you using our data or other organizations’ data for training? Why? If you are using other organizations’ data, how are you going to customize the model to our specific data environment?


Слайд 51

52 Action matters: What is the return in investment for intervention? Are we prepared to invest more... or say “no”… to patients who score low on predicted engagement? Human unpredictability: The mathematical models of human behavior are relatively immature. Socio-economics: Can today’s healthcare ecosystem expand to make a difference? Missing data: Without patient outcomes, the PA models are open loop. Social controversy: How much do we want to know about the future of our health, especially when the predictive models are uncertain? Wisdom of crowds: Suggestive analytics from “wise crowds” might be easier and more reliable than predictive analytics, until our data content improves Closing Thoughts and Questions
