Since the assignments relate to the doctor's area of specialty, a doctor may not always have patients assigned to them. One doctor will be given the position of the Chief Doctor at the Hospital. A doctor will only be the Chief Doctor for one hospital at a time. Every hospital must have a Chief Doctor. Not all doctors in the area will be a Chief Doctor for a Hospital in the area.
