How does an employer determine which level of care an injured employee needs – the ER or the clinic?

When an employee is injured, rule number one: if something is broken, if there is a lot of blood or if they are unconscious, they immediately go to the emergency room.

But for minor injuries, some employers use a 24/7 nurse hotline to determine level of injury and then direct the employee to the closest approved MPN clinic, emergency room or pharmacy.
