The "Do-It-Yourself Pancreas System" (#DIYPS) and the "Open Source Artificial Pancreas System" (#OpenAPS) movements were founded by Dana Lewis, who is also a fervent supporter of patient-centered, patient-driven, and patient-designed research. In order to increase the volume of her personal continuous glucose monitor (CGM) alarms, Dana originally invented #DIYPS in December 2013. Dana actively promoted #DIYPS online and encouraged community members from #WeAreNotWaiting to collaborate, notably on the creation of the Nightscout Project. Using the fundamental algorithm from the #DIYPS and combining it with commercially available hardware, other open source software, and tools to communicate directly with her insulin pump, she was able to "close the loop" and develop a hybrid closed loop artificial pancreas system to automate microadjustments of insulin delivery. In addition to a series of children's books like "Understanding Automated Insulin Delivery: A Basic Book for Kids, Family, and Friends of People Living with Diabetes," Dana authored the book "Automated Insulin Delivery: How Artificial Pancreas "Closed Loop" Systems can Aid You in Living with Diabetes" to help more people understand automated insulin delivery systems. Her work has been cited or discussed in numerous major media sources, including Nature, The Lancet, WNYC's "Only Human" podcast, The Wall Street Journal, Popular Science, WebMD, Diabetes Forecast, USA Today, and others.
