I think they're just asking to see if you're interested! It's an "oh by the way, since you may have trouble coming to appointments, we have an inpatient program that might be easier for you, what do you think?" sort of mention. If you're interested, see if you can get a "tour" or information about it, if you're not, just say, "no thank you." I was in outpatient therapy through a hospital too a long time ago, Georgetown University Hospital in the District of Columbia. But I never thought about outpatient. If you are too uncomfortable, I'd get another, "private" therapist?
