Forensic psychiatric inpatients served in the United States: regional and system differences

This research note presents data about regional and system variations in psychiatric inpatient services for forensic patients provided in state operated psychiatric inpatient programs in the United States in 1986. Patient census by legal status and service provision information were collected from state forensic directors. In 1986, about 5,400 patients found not guilty by reason of insanity (NGRI) and 3,200 patients found incompetent to stand trial (IST) were being served in state operated inpatient units. About 70 percent of both groups were being served in designated forensic beds. There were wide differences among the states in the volume and rates for NGRI, IST, forensic exams, and dangerous civil patients (DCP). The regional analyses revealed large variability among states within each region.
