How open source is changing healthcare. Closing the loop: How open source is changing healthcare. @DanaMLewis

Getting diagnosed with a chronic disease is like being struck by lightning. @DanaMLewis

Food, hormones, sickness, stress Insulin, exercise, sickness, stress @DanaMLewis

In diabetes, insulin is the “gas” pedal. @DanaMLewis

@DanaMLewis An artificial pancreas is the closest thing to “cruise control” for diabetes.

The current tools are not perfect…. Insulin Pump Continuous Glucose Monitor (CGM) @DanaMLewis

Because this is what it takes: @DanaMLewis

Leaving us often with this:

If we can’t change existing devices… what if we could add *new* tools? @DanaMLewis

Enter open source (and social media). @DanaMLewis

From reactive to predictive: an “open loop” @DanaMLewis

We already have in our pockets the tools needed for an “artificial pancreas”. @DanaMLewis

#OpenAPS is an open and transparent effort to make safe and effective basic Artificial Pancreas System (APS) technology widely available to reduce the burden of Type 1 diabetes. @DanaMLewis

#OpenAPS: @DanaMLewis Taking the DIY, artificial pancreas from (n=1) to (n=1)*many by: Focusing on safety Limiting dosing ability in hardware and software Using same dosing calculations a person would use Responding (or not) to unexpected data Tolerating communication failures Failing back safely to standard device operation @DanaMLewis

Who is regulating this activity? Users are. Most users “test” their own medical devices. The QA approach is even stronger when utilizing open source tools made with/by/for the community. (Individual experiments with “off label” use of medical devices are not a regulated activity.) @DanaMLewis

people with DIY closed loops in the world. There are now (n=1)*683++ people with DIY closed loops in the world. (That’s something like 4,700,000+ hours of DIY closed loop experience.) @DanaMLewis

It’s not rocket science.. @DanaMLewis

Not traditional.. But yet we are: @DanaMLewis Engineers Engineers Programmers Scientists Researchers Rocket Scientists Engineers Developers Scientists Researchers Inventors @DanaMLewis

Traditional innovation @DanaMLewis

Traditional innovation @DanaMLewis User-driven innovation

We are changing the future of health care innovation with open source. @DanaMLewis

This matters:

Imagine what else is possible if you use your open source knowledge and skills to partner with someone in your life? --- With open source, there are endless opportunities to improve lives of those we love. - @DanaMLewis

There are 10 kinds of people in the room. Those who will consider using open source skills to solve healthcare problems, and those who will not. @DanaMLewis
