This is reminiscent of an experience we had at ClearHealth with managed hospital aesthetics. Not a scientific study in any sense, but as part of rebranding a hospital group, the color scheme was changed from a neutral green to a much brighter orange. The change coincided with a small but meaningful increase in mortality for procedures done on the associated floor. Enough that we reverted to the older aesthetic. The mortality change reverted as well. Chalked it up to coincidence. This process then repeated at two other separate campuses. I can't rule out this was some sort of reverse "Hawthorne Effect" where our communications about the change were the source of the problem but it bothered me enough to mostly put an end to our appetite for large scale aesthetic redesigns.
