why are the acutes in the hospital and why dont they leave

The inmates who have treatable conditions. The hospital expects that they someday will be able to return to functioning in society. They are generally the most lucid of the inmates and the ones who can take care of themselves. The worst possible punishment is for an Acute to be turned over to the Chronic ward, such as if the nurse notices a consistent thread of disobedience that suggests the patient is not going to recover--or if a vindictive nurse just wants it to seem that way. Many don't leave because they have developed routines and friends which keeps them from getting woese.

Here is my last sentence with less errors!

Many don't leave because they have developed routines and are able to live off the state.
