This is a new era for inpatient psychiatric treatment. The vast majority of inpatient episodes today are short term (less than seven days), and patients are admitted to the hospital primarily to reduce harm to themselves or others. The primary criterion for admission and discharge is focused on risk and dangerousness. Inpatient treatment today is crisis stabilization, reevaluation of medication and psychosocial interventions, and prompt discharge. Most treatment occurs outside of the hospital in day hospitals, outpatient treatment, supported housing, and other community-based programs.
