This document discusses the concept of medical doctors as designers. It describes how the author works at the intersection of design, health, and technology. It provides examples of participatory design projects focused on redesigning medical devices like EpiPens based on input from patients. These projects aim to address problems through an approach of empathy, defining problems based on patient needs, ideating solutions collaboratively, prototyping, and iterative user testing. The author advocates for integrating design practices into healthcare work flows and designing with diverse communities rather than just for them.
