What this team seems to be doing is essentially refining the triage procedures to take ER-environment emergent problems into account, which sounds great to me. I'm sure that could be expanded to include populations other than the elderly over time, but they are obviously especially vulnerable.
I've encountered many people with complaints of ER waiting times, or being seen for 2 minutes only to be sent back to the waiting room for another hour. And I always tell them the same thing: be very happy that you get to wait in the ER, it's a good sign. If you come in and don't have to wait, you are likely in very deep shit, and the staff there will do everything they can to keep you alive.
While I'm on my soap box: some people actively abuse the ER to gain access to care more quickly, this should be actively fought and avoided. But a lot of people end up in an ER because they fear that something is bad and urgent when it's not (e.g. precordial catch + anxiety vs heart attack). Those aren't emergencies, but can be hard to distinguish from them, and so ER staff will be very happy help you.
