Researchers from the USC Schaeffer Center for Health Policy and Economics have linked tighter Medicaid policies governing antipsychotic drugs with increased incarceration rates for schizophrenic individuals.
The study comes amid media scrutiny over whether cutbacks in mental health actually save money, when other costs are taken into account.
Some health plans require an extra approval step before tests or treatments can be ordered for patients. This step - called prior authorization - is intended to encourage physicians to select cost-effective options by requiring justification for the selection of more expensive options. Likewise, prior authorization policies adopted by state Medicaid programs aim to reduce costs associated with some medications, especially those drugs used to treat schizophrenia. However, an unintended consequence of these policies may be that more mentally-ill patients are being incarcerated, raising questions about the "cost-effectiveness" of these formulary restrictions.
In a study published today in The American Journal of Managed Care, researchers found that states requiring prior authorization for atypical antipsychotics had less serious mental illness overall but higher shares of inmates with psychotic symptoms than the national average. The study concluded that prior authorization of atypical antipsychotics was associated with a 22 percent increase in the likelihood of imprisonment, compared with the likelihood in a state without such a requirement.
"This paper demonstrates that our policies around schizophrenia may be penny-wise and pound foolish," says Dana Goldman, director of the Leonard D. Schaeffer Center for Health Policy & Economics at the University of Southern California. "Limiting access to effective therapy may save States some Medicaid money in the short run, but the downstream consequences -- including more people in prisons and more criminal activity -- could be a bad deal for society."
The study examined survey data from 16,844 prison inmates in states with and without restrictive authorization requirements overlaid with state Medicaid policies and data as well as usage rates of atypical antipsychotics (a newer drug class that is frequently targeted by prior authorization requirements).
The study's findings come amid a wave of scrutiny surrounding the cost and consequences of failing to adequately provide for mental health care, including the nexus between shortchanging mental health and rising prison expenditures.
"The media has picked up on how incarcerating the mentally ill raises a range of troubling concerns, from the high cost of incarceration, to the inadequate treatment of mentally ill inmates, and the potential for self-inflicted harm among these patients," says Darius Lakdawalla, Quintiles Chair in Pharmaceutical Development and Regulatory Innovation, and a professor at the Schaeffer Center at USC. "At the same time, the American public is increasingly worried about untreated mental illness triggering violent behavior in the community. Our study suggests state Medicaid policies may be part of the solution to these problems."

About the Journal
The American Journal of Managed Care, now in its 20th year of publication, is the leading peer-reviewed journal dedicated to issues in managed care. Other titles in the AJMC family of publications are The American Journal of Pharmacy Benefits, which provides pharmacy and formulary decision makers with information to improve the efficiency and health outcomes in managing pharmaceutical care. In December 2013, AJMC introduced The American Journal of Accountable Care, which publishes research and commentary devoted to understanding changes to the healthcare system due to the 2010 Affordable Care Act. AJMC's news publications, the Evidence-Based series, bring together stakeholder views from payers, providers, policymakers and pharmaceutical leaders in the areas of oncology, diabetes management, and immunology and infectious disease.
