I've had that exact same type of call - I knew that something was definitely wrong with the patient, but I couldn't convince him to go to the hospital. Bad thing is, here in the States we don't have a roving band of psychs who can come in to check on a patient. Pretty much, if they don't want to go and they haven't expressed any desire to hurt themselves or others, and they're oriented to day/time/place, then I can't do anything for them.
