How is Evidence-Based Design Different from Research-Based Design?
That’s a good question. Research-based design―research about the environment―has been around for a very long time and I think thoughtful architects and designers have for many years employed research in an informal way when they’re designing spaces. I would say the best architects and designers have very good intuition as well that feeds into that. But just using research does not mandate in and of itself that you’re going to embark upon a formal process.
When we’re talking about evidence-based design, there is a formal process that one has to follow and this is outlined in the book. You start with the hypothesis, here’s what I think will be true if we design the nursing unit this way, and then, if you’re an architectural firm, one of the best things to do is find a consultant who is perhaps associated with an academic institution, a researcher, to work with you to develop this. I am vastly simplifying the process in this description but it starts with a literature review and figuring out with hospital leadership the best issues to study—those with the greatest leverage—then creating hypotheses and eventually developing the metrics by which you’re going to measure this at six months and 12 months after occupancy. You look at the data and what it tells you, maybe everything wasn’t successful, but some aspect of it was successful. Now you publish the outcomes—what worked and what didn’t work—and then the next hospital, or next 20 or 40 hospitals, doesn’t make that same mistake. They can look at what you did and say, “that was really effective for this sub-group of patients, which was great.”
And over time, I’m sure it will take at least 10 years to have a large enough database built-up, one learns from another and another—as the knowledge base grows. One sees greater rigor coming from Medicare; you see it in clinical care the past few years, the work that IHI, the Institute for Healthcare Improvement, has embarked upon. That’s where we’re going and design has to follow, it has to be as rigorous.
