Our guest on ST Medical Monday is Dr. Bon Ku, an ER doc and Assistant Dean for Health and Design at the Sidney Kimmel Medical College at Thomas Jefferson University. Dr. Ku is also the co-author of a new book, "Health Design Thinking: Creating Products and Services for Better Health." This novel and fascinating work argues that the principles of human-centered design can and should be applied to today's health care challenges. The book's focal points range from the design of drug packaging and exam rooms to the use of internet-connected devices for early detection of breast cancer. As Dr. Ku tells us, health design thinking uses play and experimentation -- rather than a fixed methodology -- and thus employs interviews, observations, diagrams, storytelling, physical models, and role playing; design teams focus not on technology but on real-world problems faced by patients and clinicians.
