Outpatient commitment—also called assisted outpatient treatment (AOT) or community treatment orders (CTO)—refers to a civil court procedure wherein a legal process orders an individual diagnosed with a severe mental disorder to adhere to an outpatient treatment plan designed to prevent further deterioration or recurrence that is harmful to themselves or others.

This form of involuntary treatment is distinct from involuntary commitment in that the individual subject to the order continues to live in their home community rather than being detained in hospital or incarcerated. The individual may be subject to rapid recall to hospital, including medication over objections, if the conditions of the order are broken, and the person's mental health deteriorates. This generally means taking psychiatric medication as directed and may also include attending appointments with a mental health professional, and sometimes even not to take non-prescribed illicit drugs and not associate with certain people or in certain places deemed to have been linked to a deterioration in mental health in that individual.

The criteria and process for outpatient commitment are established by law, which vary among nations and, in the U.S. and Canada, among states or provinces. Some jurisdictions require court hearings, where a judge will make a court order, and others require that treating psychiatrists comply with a set of requirements before compulsory treatment is instituted. When a court process is not required, there is usually a form of appeal to the courts or appeal to or scrutiny by tribunals set up for that purpose. Community treatment laws have generally followed the worldwide trend of community treatment. See mental health law for details of countries which do not have laws that regulate compulsory treatment.

Terminology In the United States the term "assisted outpatient treatment" (AOT) is often used and refers to a process whereby a judge orders a qualifying person with symptoms of severe untreated mental illness to adhere to a mental health treatment plan while living in the community. The plan typically includes medication and may include other forms of treatment as well. Patients are often monitored and assigned to case managers or a community dedicated to treating mental health known as assertive community treatment (ACT).

Australia, Canada, England, and New Zealand use the term "community treatment order" (CTO).

Comparison to inpatient commitment

The terminology, "outpatient commitment", and legal construction often equate outpatient commitment with inpatient commitment but providing the patient more freedom. In practice, outpatient commitment may be used in situations where commitment would not be used because it is cheaper than inpatient commitment; seen as less draconian; and protects mental health professionals from moral, civil or criminal liability.

Preventive use

Outpatient commitment is used in some countries to prevent relapse of mental disorders, as many mental disorders are episodic in nature (for example bipolar disorder or schizophrenia) and it can be difficult to predict whether a mental disorder will reoccur. Some countries use outpatient commitment for first episode psychosis (FEP).

Implementation Discussions of "outpatient commitment" began in the psychiatry community in the 1980s following deinstitutionalization, a trend that led to the widespread closure of public psychiatric hospitals and resulted in the discharge of large numbers of people with mental illness to the community.

Europe Denmark Denmark introduced outpatient commitment in 2010 with the Mental Health Act ().

Germany In Germany, CTOs were resumed in 2015 (formerly only for forensic psychiatry). Laws regarding implementations are distincts between lander.

France The CTOs are renewed every month. They were introduced under Nicolas Sarkozy presidency. Persons committed are registered on a national file accessible by police, even if they are not suspected of breaking the law.

The Netherlands Dutch law provides for community treatment orders, and an individual who does not comply with the terms of their CTO may be subject to immediate involuntary commitment.

Norway When Norway introduced outpatient commitment in the 1961 Mental Health Act, it could only be mandated for individuals who had previously been admitted for inpatient treatment. Revisions in 1999 and 2006 provided for outpatient commitment without previous inpatient treatment, but this provision is seldom used.

Sweden In Sweden, the Compulsory Psychiatric Care Act () provides for an administrative court to mandate psychiatric treatment to prevent harm to the individual or others. The law was created in 1991 and revised in 2008.

England and Wales Changes in service provision and amendments to the Mental Health Act in England and Wales have increased the scope for compulsion in the community. The Mental Health Act 2007 introduced community treatment orders (CTOs). CTOs are legally defined as a form of outpatient leave for individuals detained under section 3 of the Mental Health Act. As such, only members of the medical community are involved in issuing a CTO, though both the section 3 detention underlying the CTO and the CTO itself can be appealed to the Mental Health Tribunal where a panel consisting of medical doctors and a judge will make a decision.The legislation in the UK specifically allows CTOs to be issued after a single admission to hospital for treatment. However, the Royal College of Psychiatrists suggested limiting CTOs to patients with a history of noncompliance and hospitalization, when it reviewed the current mental health legislation.

John Mayer Chamberlain argues that this legislation was triggered by the Killing of Jonathan Zito by an individual who had interactions with mental health services prior this event, which led the then conservative government to argue for CTOs.

A review of patient data in London found that the average duration of a CTO in the UK was 3 years. Black people in the UK are more than ten times as likely to be under a CTO as white people. Concerns have been raised about the inability of Independent mental health advocates (IHMAs) to provide services to those under CTOs, since IMHAs cannot make contact with service users under CTOs and case workers could act as gatekeepers not providing referrals.

In a 2021 paper reviewing the mental health act, the UK government proposed a new form of indefinite outpatient commitment allowing for deprivation of liberties an continuous supervision termed supervised discharge. This discharge would be reviewed yearly, and only apply to individuals who would not benefit from treatment in a hospital setting and would be based on risk. Further, this legislation would only apply to restricted patients who have been diverted to the mental health care system from courts.

Scotland

Scotland has a different community commitment regime from England and Wales introduced in the 2003 Mental Health Act. There is ongoing debate in the UK on the place of coercion and compulsion in community mental health care.

Luxembourg Patients may be recalled if they don't abide to conditions on residence or medical supervision decided by a psychiatrist on discharge for 3 months after having been released from an involuntary commitment.

North America In the last decade of the 20th century and the first of the 21st, "outpatient commitment" laws were passed in a number of U.S. states and jurisdictions in Canada.

Canada

In the mid-1990s, Saskatchewan became the first Canadian province to implement community treatment orders, and Ontario followed in 2000. New Brunswick was the only province without legislation that provided for either CTOs or extended leave.

United States

44 U.S. states had enacted some version of an outpatient commitment law. In some cases, passage of the laws followed widely publicized tragedies, such as the murders of Laura Wilcox and Kendra Webdale.

Oceania Australia and New Zealand introduced community treatment orders in the 1980s and 1990s.

Australia In the Australian state of Victoria, community treatment orders last for a maximum of six months but can be renewed after review by a tribunal.

Controversy

Proponents have argued that outpatient commitment improves mental health, increases the effectiveness of treatment, lowers the incidence of homelessness, arrest, incarceration, and hospitalization, and reduces costs. Opponents of outpatient commitment laws argue that they unnecessarily limit freedom, force people to ingest dangerous medications, impede their human rights, or are applied with racial and socioeconomic biases.

Arguments for and proponents

While many outpatient commitment laws have been passed in response to violent acts committed by people with mental illness, most proponents involved in the outpatient commitment debate also make arguments based on the quality of life and cost associated with untreated mental illness and "revolving door patients" who experience a cycle of hospitalization, treatment and stabilization, release, and decompensation. While the cost of repeated hospitalizations is indisputable, quality-of-life arguments rest on an understanding of mental illness as an undesirable and dangerous state of being. Outpatient commitment proponents point to studies performed in North Carolina and New York that have found some positive impact of court-ordered outpatient treatment. Proponents include: Substance Abuse and Mental Health Services Administration (SAMHSA), U.S. Department of Justice, Agency for Healthcare Research and Quality (AHRQ), U. S Department of Health and Human Services, American Psychiatric Association, National Alliance on Mental Illness, International Association of Chiefs of Police. SAMHSA included Assisted Outpatient Treatment in their National Registry of Evidence Based Program and Practices. Crime Solutions: Management Strategies to Reduce Psychiatric Readmissions. The Treatment Advocacy Center are an advocacy group that campaign for the use of outpatient commitment.

A systematic review in 2016 looked at around 200 papers investigating the effectiveness of CTOs for patient outcomes. It found that non-randomized trials had dramatically varying results and that no randomized controlled trials showed any benefits to the patient for outpatient commitment apart from a reduction in the risk of being the victim of crime.

Due to legal, bureaucratic, and social factors, the same interventions can have different effects in different countries.

Cost

Research published in 2013 showed that Kendra's Law in New York, which served about 2,500 patients at a cost of $32 million, had positive results in terms of net cost and reduced arrests. About $125 million is also spent annually on improved outpatient treatment for patients who are not subject to the law. In contrast to New York, despite the wide adoption of outpatient commitment, the programs were generally not adequately funded.

"Although numerous AOT programs currently operate across the United States, it is clear that the intervention is vastly underutilized."

Arrests, danger, and violence The National Institute of Justice considers assisted outpatient treatment an effective crime prevention program. Some studies in the US have found that AOT programs have reduced the chances of arrest. Kendra's Law has lowered the risk of violent behaviors and reduced thoughts about suicide.

Outcomes and hospital admissions AOT "programs improve adherence with outpatient treatment and have been shown to lead to significantly fewer emergency commitments, hospital admissions, and hospital days as well as a reduction in arrests and violent behavior."
