I found a really interesting paper on the development of a dashboard for an emergency room in Seoul. The researchers designed the dashboard iteratively (over several rounds) then tested its usability. The paper is:

There were 2 subprojects: a dashboard for providers and a dashboard for patients and families. The dashboards fell under a Happiness project at the institution (called “Happinovation” – Happy innovation) that sought to enhance patient and provider happiness through process and hardware innovations.
There were three dashboard principles: (1) Anytime, Anywhere, at a Glance, (2) Minimal Interruption to Workflow, and (3) Protect Patient Privacy. And, there were three design principles: (1) Geographical Layout, (2) Patient-Level Alert, and (3) Real-Time Summary Data.
The researchers used the System Usability Scale (SUS) to obtain and measure participants’ views on the usability of the dashboard. The SUS score was a high 67.6 points.
There was a lot of data to include in the dashboards so they were a little crowded/busy. I personally felt that they were too dark, but the dark color made the numbers pop (more visible).
