Where the untreated went
Deinstitutionalization was not a failure of idea but of execution. The Community Mental Health Act of 1963 envisioned 2,000 community mental health centers. Fewer than half were ever built, and most were underfunded within a decade.
The IMD exclusion — a Medicaid provision barring federal payment for psychiatric hospitals with more than 16 beds — created a perverse incentive: states saved money by closing hospitals and shifting costs to jails, ERs, and the streets.
The result is a system of transinstitutionalization: patients moved not from institutions to communities, but from one form of institutional confinement to another. The three largest psychiatric facilities in the United States are now the Los Angeles County Jail, Cook County Jail, and Rikers Island.
