New major study shows AOT cuts costs in half
The Cost of Assisted Outpatient Treatment:
Requiring Some Patients to Get Mental Health Treatment Saves Money
DURHAM, N.C. – Mandating outpatient treatment for certain people with severe mental illness, results in substantial cost savings by cutting hospitalizations and increasing outpatient care, according to a financial analysis led by researchers at Duke Medicine
The finding – focusing on a program in New York termed Assisted Outpatient Commitment (AOT), or "Kendra's Law" ("Laura's Law in California)- provides a key piece of information in the ongoing policy debate about appropriate treatment approaches for people with serious mental illness. The issue has been particularly important in light of recent mass shootings by gunmen who have had mental health diagnoses.
Appearing July 30, 2013, in the American Journal of Psychiatry, the study found that treatment costs for a group of frequently hospitalized patients declined 50 percent in New York City after the first year of an outpatient commitment program, and dropped another 13 percent the second year. Even larger cost savings were reported in five other New York counties that were also part of the analysis.
All but a handful of states have some form of assisted outpatient treatment program, which requires certain high-risk patients to participate in community-based treatments. But the programs have only been used sporadically in most states. Impediments include concerns about costs, potential coercion of vulnerable people and liability for patients who harm themselves or others.
"At least from a cost standpoint, our evidence shows that outpatient commitment programs could be an effective policy," said lead author Jeffrey W. Swanson, PhD., M.A., a professor in psychiatry and behavioral sciences at Duke University.
Swanson and colleagues conducted a comprehensive cost analysis of New York's assisted outpatient treatment program, which mandates community-based care for severely mentally ill patients who have a history of revolving-door admissions to psychiatric hospitals. Such admissions are the most expensive component of mental health services.
The researchers analyzed services used by 634 patients under court order to participate in community care, including 520 patients in New York City and 114 from other counties.
Psychiatric hospitalization rates fell steeply among participants in the program. During the year before mandated community treatment, 180 of the 520 New York City participants were admitted to a state psychiatric hospital, and 373 were admitted to a psychiatric unit at other hospitals. In the year after starting the program, 70 were admitted to a state psychiatric hospital and 245 were admitted at other hospitals. Similar declines occurred in counties outside of New York City.
As hospitalizations fell, so did costs. People selected for the program had incurred, on average, more than $104,000 in mental health service costs during the preceding year. These costs declined to $59,924 per patient in New York City, and $53,683 among the other county participants, in the first year of the program. In the second year of the program, costs continued to decline, to $52,386 for the New York City participants and $39,142 for those in the counties.
The savings were realized even as expenses for outpatient services more than doubled, with patients increasingly using case management support and transportation services, making clinical visits, seeking addiction treatments and refilling prescriptions for medications.
"You wind up preventing the crises by keeping people in community treatment, and that's much less expensive," Swanson said. "You don't have to prevent that many hospitalizations to have a big cost offset, because hospitalizations are so expensive compared to outpatient treatments and services."
While patients in the mandatory program used more mental health services, the program had a mixed impact on criminal justice system involvement, which affects many people with untreated serious mental illness. Fewer of the study participants were arrested and jailed after initiating mandatory outpatient treatment, but the costs associated with their incarcerations were roughly the same.
Swartz said the research adds context to policy debates about how to care for people with severe mental illness, particularly in times of tight public budgets, and suggests that involuntary outpatient treatment programs might serve as an alternative to high-cost involuntary hospital admissions.
"If applied to the right targeted population, mandatory outpatient treatment can have a dramatic impact on the cost of mental health services," Swartz said.
Objective: The authors assessed a state’s net costs for assisted outpatient treatment, a controversial court-ordered program of community-based mental health services designed to improve outcomes for persons with serious mental illness and a history of repeated hospitalizations attributable to nonadherence with outpatient treatment.
Method: A comprehensive cost analysis was conducted using 36 months of observational data for 634 assisted outpatient treatment participants and 255 voluntary recipients of intensive community-based treatment in New York City and in five counties elsewhere in New York State. Administrative, budgetary, and service claims data were used to calculate and summarize costs for program administration, legal and court services, mental health and other medical treatment, and criminal justice involvement. Adjusted effects of assisted outpatient treatment and voluntary intensive services on total service costs were examined using multivariate time-series regression analysis.
Results: In the New York City sample, net costs declined 50% in the first year after assisted outpatient treatment began and an additional 13% in the second year. In the five-county sample, costs declined 62% in the first year and an additional 27% in the second year. Psychotropic drug costs increased during the first year after initiation of assisted outpatient treatment, by 40% and 44% in the city and five-county samples, respectively. Regression analyses revealed significant declines in costs associated with both assisted outpatient treatment and voluntary participation in intensive services, although the cost declines associated with assisted outpatient treatment were about twice as large as those seen for voluntary services.
Conclusions: Assisted outpatient treatment requires a substantial investment of state resources but can reduce overall service costs for persons with serious mental illness. For those who do not qualify for assisted outpatient treatment, voluntary participation in intensive community-based services may also reduce overall service costs over time, depending on characteristics of the target population and local service system.
