The deinstitutionalisation of mental health treatment refers to the transition of care away from acute care to community-based care.
Acute care refers to care occurring within a hospital (or ‘asylum’) where patients are admitted, sometimes involuntarily, and reside in the hospital for the duration of their treatment.
Community based care refers to non-residential treatment, typically occurring within outpatient clinics or the patient’s own home.
Relative to acute care, community care is less intense, occurring at most a few times a week, as opposed to every day. Since 1950, the number of UK acute beds has reduced from 150,000 to 27,000.
