The University of Colorado Hospital in Aurora says it will close its inpatient psychiatric unit in January to free up more beds for other services.
The hospital says it's facing an overall shortage of beds and increasing demands in other areas, including cancer treatment, transfers of severely ill patients and emergency services.
In a written statement, the hospital board also blames "diminishing public resources for behavioral health."
Officials say the hospital served 735 people through inpatient psychiatric services last year.
The hospital will continue to offer outpatient psychiatric services.
