Shattuck hospital is where they generally send you when you need mental health care and well as physical health care needs to be addressed at the same time. I believe they do a lot of HIV/AIDS long term services and care as well as have a fairly comprehensive homeless transitional care center/substance abuse treatment program. A friend of mine did a rotation there a few years ago and said it was hell and full of scary deadbeats
Bridgewater State Prison is just that - a state prison. It has a state hospital in the complex for convicts detainees who need court ordered psychiatric care.
