Crossing state lines, a man arrives alone in San Francisco, having traveled by bus on a 1-way ticket provided by a psychiatric hospital in his home state. He is disoriented,with few possessions,lacks medications and medical records, and calls 911 as he was instructed. He is brought to the county psychiatric emergency service, which,hectic and often over capacity,treats nearly 6000 patients annually (of which 39% are not San Francisco residents).The patient needs housing,a psychiatrist,case manager, primary care provider, and transfer of Medicaid or general assistance—a package known colloquially astheSan Francisco Special.Placements are challenging— the county hospital reduced its acute inpatient psychiatrycapacity50% in thelast 5years owing to budget short-falls—yet out-of-state visitors are not turned away. Shipping patients across state lines on 1-way bus fares without a treatment plan or identified residence is referred to as bus therapy, a form of patient dumping. In April 2013, the Sacramento Bee reported that more than 1500 mentally ill and questionably discharged patients from Nevada were transported by Greyhound bus to states across the country in the past 5 years.1 One-third were sent to California—San Francisco and Los Angeles counties initiated formal investigations. Patient dumping is not new. In the 1970s, with US mental health deinstitutionalization, psychiatric beds were reduced, uninsured patients were often turned away, and more patients sought emergency care. The 1986 Emergency Medical Treatment and Active Labor Act was intended to reduce patient dumping, by requiring emergency departments to screen and stabilize presenting patients (a subjective process). With continued reductions in inpatient capacity (4000 acute beds reduced nationally between 2010-2012), the impact on emergency services is expected to grow.2 People with mental illness have the right to relocate willingly and preferably when in stable condition and with facilitated continuity of care.On the other hand,patient dumping has many implications for psychiatric patients, especially the severely mentally ill. Obvious ones are potential harms owing to decompensation,poor self-care, loss of support networks, vulnerability to victimization, and/or failure to access care. In 2009, 40% of adults with serious mental illness went untreated.3
