In October 2011 I participated in a workshop and speaker panel coordinated by the Center for Health Design. The Design for Patient Safety Seminar included experts from healthcare, architecture and humman factors; and I served as the sole representative from product design.
The speaker videos from the event are available online and include my presentation on the similarities and differences in how safety is considered in the design of products versus healthcare environments. It may surprise you to learn which area is more safety-focused.
My presentation starts around the 15:00 minute mark in the presentation.
