PreambleI believe that people are drawn to ideas that reflect imagination and vision.Up until recently, the field of health IT has lacked such an idea, one that would unite all the stakeholders and attract the brightest minds from a range of disciplines.By the end of this hour, I hope to convince you that the Learning Health System is that key idea.

The Plight in Words
• Spending 18% of GDP on health, which is unsustainable– 25% of which is “wasted”
• 45th in infant mortality. Japan and Sweden have a rate 40% of ours.
• New estimate: 200,000 to 400,000 die each year in hospitals due to medical errors
• Among five highly developed nations, the U.S. is last or next-to-last on five indicators of a “high functioning” health system 5

A High Functioning LHS Will Make These (and Other) Things Possible“17 years to 17 months, or maybe 17 weeks or even 17 hours…“
• Over time, the best “personalized” dosage of a new drug is learned based on patient experience. The current optimal dosage algorithm is automatically implemented nationwide in EHR systems.
• During an epidemic, new cases are reported directly from EHRs and the spread of the disease is predicted. Clinicians are alerted as the epidemic approaches their practice areas.
• A patient facing a difficult medical decision describes her case. She discovers the experiences of other patients like her. 13

The LHS: One Infrastructure that Supports
• Research– Clinical– Comparative effectiveness– Translational
• Public Health– Surveillance– Situational Awareness
• Quality Improvement– Health process and outcomes research– Best practice dissemination
• Consumer Engagement– Knowledge-driven decision making

The LHS as Currently Envisioned
• A federation– Not a centralized database
• Grounded in public trust and patient engagement
• Participatory governance• An “Ultra Large Scale” System
– “Just enough” standardization– Supports innovation around standards

• At every level of scale, it looks pretty much the same
• Local, regional, national, global• A system of like sub-systems

• Perspective: Jan 3, 2013• “Code Red and Blue — Safely Limiting Health
Care’s GDP Footprint”Arnold Milstein, M.D., M.P.H.
…U.S. health care needs to adopt new work methods, outlined in the Institute of Medicine’s vision for a learning health system… Such methods would enable clinicians and health care managers to more rapidly improve value by continuously examining current clinical workflows, management tools from other service industries, burgeoning databases, and advances in applied sciences (especially health psychology and information, communication, and materials technologies). They could then use the insights gained to design and test innovations for better fulfilling patients’ health goals with less spending and rapidly scaling successful innovations. 20

Progress: Learning “Islands”
• Organizations that have become Learning Health Systems at their level of scale.
• But don’t routinely connect with other islands.

Progress: Grassroots Movement• National “Summit” convened in May 2012 to
envision LHS as set of shared beliefs• A Dumbarton Oaks conference for the LHS• ~ 70 organizations represented at the National
Press Club• Resulted in 10 consensus Core Values• 56 organizations have formally endorsed
• Giving rise to a Learning Health Community

Approaching a “First” National System
1. Words: calls and reports
2. “Learning Islands”
3. Data federations and networks
4. Grant programs
5. A grassroots coalition of the willing
But this “first” system will not turn the Titanic. We need to set our sights on a higher-functioning system.

A High-Functioning LHS
Would meet four system-level requirements:1. Trusted and Valued by All Stakeholders2. Economically Sustainable and Self-
Governing3. Stable, Rapidly-Functioning, Certifiable,
Adaptable, and Self-Improving4. Capable of Engendering a Virtuous
Cycle of Health Improvement
30

Workshop Findings at Two Levels
1. What we were asked to do: the research questions that must be addressed to meet LHS system level requirements
– 106 questions organized into four categories and 19 sub-categories
2. Something transcendent: A vision of a science of learning systems necessary to address these questions (and achieve the LHS) 31
![Page 32: Informatics for the Nationwide Learning Health System Charles P. Friedman Professor of Information and Public Health University of Michigan University.](https://reader034.fdocuments.us/reader034/viewer/2022052701/56649ccd5503460f94997553/html5/thumbnails/32.jpg)
Sample Questions (2/106)• An LHS that is Trusted and Valued by All All
Stakeholders– What properties of heterogeneous, routinely
collected clinical data, including methods in place to manage and curate them, will engender confidence and trust in the knowledge generated by the LHS?
• An LHS that is Economically Sustainable and Self-Governing– What ingredients essential to standing up and
sustaining the LHS have no private rationale for funding or are unlikely to be funded privately, and therefore should be considered for catalysis stemming from public funding? 32
![Page 33: Informatics for the Nationwide Learning Health System Charles P. Friedman Professor of Information and Public Health University of Michigan University.](https://reader034.fdocuments.us/reader034/viewer/2022052701/56649ccd5503460f94997553/html5/thumbnails/33.jpg)
Sample Questions (2/106)• An LHS that is Stable, Rapidly-Functioning,
Certifiable, Adaptable, and Self-Improving– How do we make data sufficiently self-
describing so that, for example, the system might be able to identify, without human intervention, data that are most relevant to addressing a question?
• An LHS that is Capable of Engendering a Virtuous Cycle of Health Improvement– How do we build an LHS that is smart enough
to explain its own inferences: how it learns, what it learns, and what it has already learned?

History Lesson: the Panama Canal
37
They tried to build the Panama Canal the same way, and failed. They didn’t have the right perspective on the problem.
The French built the Suez Canal as a ditch in the desert.

The Transcendent Workshop Product
• The right perspective for the LHS challenge• The LHS makes the irrefutable case for a science of
cyber-social ecosystems that will be a science of learning systems closely aligned with informatics
• Fundamental principles to enable the effective design, analysis, construction, governance, operation and evolution of ultra-large systems such as the LHS
39
![Page 40: Informatics for the Nationwide Learning Health System Charles P. Friedman Professor of Information and Public Health University of Michigan University.](https://reader034.fdocuments.us/reader034/viewer/2022052701/56649ccd5503460f94997553/html5/thumbnails/40.jpg)
Key Precepts of Cyber-Social Ecosystems
• Complex learning processes are effected by networks of people, institutions, and digital computing machines.
• These networks self-organize and evolve.• The system components are loosely coupled and
generally operate in their own self-interest• The system as a whole, not just the digital
infrastructure, but also networks of people and institutions, will have to be understood as parts of an information processing ecosystem.
40
![Page 41: Informatics for the Nationwide Learning Health System Charles P. Friedman Professor of Information and Public Health University of Michigan University.](https://reader034.fdocuments.us/reader034/viewer/2022052701/56649ccd5503460f94997553/html5/thumbnails/41.jpg)
This Framing is Mission Critical• The cyber-social ecosystem perspective must
drive the achievement of the LHS– Otherwise, we will fail like the French attempt to
build the Panama Canal• Key implications for Utah and the nation:
– Take an evolutionary approach (less is more)– Design for adaptation– Embrace the fractal– Attend to all parts of the virtuous cycle– Attend to all domains (care, empowerment, public
health, research)– Engage all stakeholders
41

In Sum
• Our health system is headed directly for the iceberg
• A high-functioning LHS, a single multi-purpose infrastructure, can turn the “Titanic”
• A science of cyber-social ecosystems, a science of learning systems, can guide achievement of the high functioning LHS 42
![Page 43: Informatics for the Nationwide Learning Health System Charles P. Friedman Professor of Information and Public Health University of Michigan University.](https://reader034.fdocuments.us/reader034/viewer/2022052701/56649ccd5503460f94997553/html5/thumbnails/43.jpg)
And…
As the University of Utah becomes a learning entity, it should:• Adopt the cyber-social ecosystem perspective
to achieve a high-functioning system• Engage with the national movement (and not
be an island)
