Successful involuntary psychiatric outpatient treatment requires identifying patients who are suited to such treatment and ensuring that the service system is able to deliver the treatment. Based on his clinical experience, the author has developed ten sequential guidelines that can help clinicians identify patients who are appropriate for involuntary outpatient treatment. The sequential order of the guidelines means that a patient must meet the criteria for each guideline before being evaluated on subsequent guidelines. The guidelines assume that the patient has a chronic mental illness and a history of dangerousness to self or others because of that illness. The author believes that achieving consensus about who should receive involuntary outpatient treatment is an important first step in permitting evaluation of the efficacy of the approach.
