The concept of "co-creation," borrowed from the business sector, integrates patients into the process of developing health care products and systems, so that their perspective and input can ultimately inform the care they receive. It's a simple but revolutionary idea, and it's being applied across health care sectors – including in the way health care is designed. This month on Ethics Talk, we talk with designer John Meyer about what it means to think about design in health care, hear from Laura Webb, a patient who has taken a central role in creating a health care application that directly benefits her, and explore how "design thinking" can transform medical education with Dr. Bon Ku.
