Upon his or her discharge from, or upon leaving, an approved public or private treatment facility, a patient who was receiving treatment for alcoholism or for drug addiction or dependency shall be encouraged to consent to appropriate outpatient, intermediate care, or other after-care treatment. If it appears to the administrator in charge of the treatment facility, upon the advice of the attending physician, that the patient is an alcoholic or drug addict who requires such help, the division shall make a reasonable effort to arrange for assistance in obtaining supportive services and residential facilities for the patient, such as maintenance in a hotel or halfway house operated by the division or by any other public or private agency.
