Very Bad Idea
The purpose of an Emergency Room is supposedly Emergency Medical care. Anything that can be arranged by reservation already has coverage, it is called the Family Physician's appointment schedule. Emergency Physicians' roles are to treat life and limb threatening emergencies, not things such as a cold. The reason for a backlog seeing people with minor ailments is because they are placed at the lowest point of triage. Legally an ER cannot send anyone away without evaluation. Please ditch this idea and promote appropriate utilization of the Family Physician.
