ERM? Did you mean the emergency department? https://carle.org/locations/carle-foundation-hospital/emergency-services
You can ask at the front desk of the emergency department where you check in how long your wait will be. I visited the emergency room about a hundred times and my wait times have been anywhere from 5 minutes to 4 hours. This hospital overvalues everything it does so often the waiting list for everything are far longer than you can possibly imagine.
I have not had that type of visit. But usually My wait times for any appt is about 5-15 minutes.
