The troubling U.S. incarceration rate ñ a direct result of the governmental policy of overcriminalization ñ has been a frequent topic on this blog (here, here, here, here, here,here, here, here, here, here and here).

In this post from last fall, Scott Henson notes that Kings College in London now has available here its latest "World Prison Population List" that reflects that the United States remains a world leader in incarceration rate by a large margin:

The United States has the highest prison population rate in the world, 756 per 100,000 of the national population, followed by Russia (629), Rwanda (604), St Kitts & Nevis (588), Cuba (c.531), U.S. Virgin Is. (512), British Virgin Is. (488), Palau (478), Belarus (468), Belize (455), Bahamas (422), Georgia (415), American Samoa (410), Grenada (408) and Anguilla (401).

Americaís dubious drug prohibition policy is one of the reasons for the high incarceration rate. However, as this Houston Politics/Chronicle blog post notes, this National Sheriffsí Association survey (H/T Doug Berman) reports that the United States imprisons many more mentally ill citizens than treating them in hospitals. This press release on the survey summarizes the sad story:

Americans with severe mental illnesses are three times more likely to be in jail or prison than in a psychiatric hospital, according to "More Mentally Ill Persons Are in Jails and Prisons Than Hospitals: A Survey of the States," a new report by the Treatment Advocacy Center and the National Sheriffs’ Association.

"America’s jails and prisons have once again become our mental hospitals," said James Pavle, executive director of the Treatment Advocacy Center, a nonprofit dedicated to removing barriers to timely and effective treatment of severe mental illnesses. "With minimal exception, incarceration has replaced hospitalization for thousands of individuals in every single state."

The odds of a seriously mentally ill individual being imprisoned rather than hospitalized are 3.2 to 1, state data shows. The report compares statistics from the U.S. Department of Health and Human Services and the Bureau of Justice Statistics collected during 2004 and 2005, respectively. The report also found a very strong correlation between those states that have more mentally ill persons in jails and prisons and those states that are spending less money on mental health services.

Severely mentally ill individuals suffering from diseases of the brain, such as schizophrenia and bipolar disorder, often do not receive the treatment they need in a hospital or outpatient setting. The consequences can be devastating ñ homelessness, victimization, incarceration, repeated hospitalization, and death.

"The present situation, whereby individuals with serious mental illnesses are being put into jails and prisons rather than into hospitals, is a disgrace to American medicine and to common decency and fairness," said study author E. Fuller Torrey, M.D., a research psychiatrist and founder of the Treatment Advocacy Center. "If societies are judged by how they treat their most disabled members, our society will be judged harshly indeed."

Recent studies suggest that at least 16 percent of inmates in jails and prisons have a serious mental illness. According to author and National Sheriffs’ Association Executive Director Aaron Kennard, "Jails and prisons are not designed for treating patients, and law enforcement officials are not trained to be mental health professionals."

Ratios of imprisonment versus hospitalization vary from state to state, as the report indicates. On the low end, North Dakota has an equal number of mentally ill individuals in hospitals as in jails or prisons. By contrast, Arizona and Nevada have 10 times as many mentally ill individuals in prisons and jails than in hospitals.

Among the study’s recommended solutions are for states to adopt effective assisted outpatient treatment laws to keep individuals with untreated brain disorders out of the criminal justice system and in treatment. Assisted outpatient treatment is a viable alternative to inpatient hospitalization because it allows courts to order certain individuals with brain disorders to comply with treatment while living in the community. Studies show assisted outpatient treatment drastically reduces hospitalization, homelessness, arrest, and incarceration among people with severe psychiatric disorders, while increasing adherence to treatment and overall quality of life.  .   .   .
