Frequently Asked Questions

How do I know whether I need mental health hospitalization?

Hospital-level or structured behavioral health care may be appropriate when symptoms, substance use, trauma, or a psychiatric crisis significantly affect safety or daily functioning. An admissions consultation and clinical assessment can help determine the appropriate level of care. If someone is in immediate danger or may harm themselves or others, seek emergency assistance rather than waiting for a routine consultation.
