The impact of insanity acquittees on Missouri's public mental health system.

Even though state departments of mental health have primary responsibility for the care, custody, and treatment of insanity acquittees, the impact of insanity acquittees on the public mental health system is generally lacking in policy discussions and as a topic for policy research. This issue has received increased attention in Missouri, where insanity acquittees now occupy half of the long-term public psychiatric hospital beds. This article examines the presence of Missouri's insanity acquittees on the state's public mental health system and includes the impact on goals, fiscal costs, inpatient and community psychiatric services, and inpatient treatment staff. As states consider managed care and other cost containment measures, it remains to be seen if the high costs associated with extensive use of hospitalization of insanity acquittees to promote public safety will influence policy changes to more community-based insanity acquittee systems.
