If this is like a patient first center or Urgent care center with mainly non-urgent patients 6-1 is about the norm around here. If this is however a true ER anything above 1-4 can be a serious liability. Does this place actually have a triage system or are the patients taken on a first come, first serve basis?
If this is a true ER, with medics bringing in patients I would suggest you look elseware where you would have more resources.
