The “Guide to Evidence-Based Art” was published in 2008. In ten years, a lot of new data, new questions, and new ideas have made it clear that the guide must be updated. The consequences are real.

This guide acts as a sort of specification system for hospital systems and architects who seek qualified professional art consultants to outfit their new spaces with healing art programs. The guide does not set rules, but it is still treated as a sort of rule-book, entirely contrary to the first principle of evidence-based design.
