Patient dumping or homeless dumping is the practice of hospitals and emergency services inappropriately releasing homeless or indigent patients to public hospitals or on the streets instead of placing them with a homeless shelter or retaining them, especially when they may require expensive medical care with minimal government reimbursement from Medicaid or Medicare. The term homeless dumping has been used since the late 19th century and resurfaced throughout the 20th century alongside legislation and policy changes aimed at addressing the issue. Studies of the issue have indicated mixed results from the United States' policy interventions and have proposed varying ideas to remedy the problem.

Deinstitutionalisation is the process of replacing long-stay psychiatric hospitals with less isolated community mental health services for those diagnosed with a mental disorder or developmental disability. In the late 20th century, it led to the closure of many psychiatric hospitals, as patients were increasingly cared for at home, in halfway houses and clinics, in regular hospitals, or not at all.
