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. When a serious medical condition arises, a patient will be admitted to the closest hospital. A hospital may have many patients, but a patient will only be admitted to one hospital.

An individual is not considered a patient of the hospital unless they have been admitted to the hospital and are waiting to be treated.
